Objectives:
The University of Leeds requires access to NHS England data for the purpose of the following research project: Yorkshire Cancer Research Bowel Cancer Improvement Programme (YCRBCIP). The overall aims of this programme are to evaluate how much bowel cancer outcomes can be improved by engaging with multidisciplinary teams (MDTs), by collecting, and feeding back to them high quality performance data and providing training and supervision for specialists where a need is identified.
The programme involves both retrospective and prospective data collection. Part of the prospective element involves the collection of two data components covered by one consent process: Patient Reported Outcome Measures (PROMs) and tissue samples. Bowel cancer patients are recruited from the 14 Colorectal Cancer MDTs based in the 14 hospital trusts across Yorkshire and the Humber. PROMs data are collected by asking participants to complete questionnaires covering a range of generic, cancer-specific and bowel cancer specific measures in addition to socio-demographic characteristics at three time points: baseline, twelve months post diagnosis and around three years post diagnosis. Tissue sample data are collected from some of their tissue that is excess to that required for diagnosis and treatment, and sent to the research team to undertake additional novel biomarker testing.
To increase the amount and depth of diagnostic and treatment information available, the prospective data need to be linked with existing routine datasets held by NHS England on an annual basis over the term of the agreement, including:
NDRS National Cancer Registration Dataset
NDRS Hospital Episodes Statistics (admissions)
NDRS National Radiotherapy Dataset
NDRS Systemic Anticancer Therapy Dataset
NDRS Diagnostic Imaging Dataset
NDRS Rapid Registration Dataset
The quantum of data required is to allow the research team an integrated dataset
which provides basic information about bowel cancer care in Yorkshire and high quality intelligence about the management of such patients.
The resulting linked dataset held by the University of Leeds will be identifiable. The data requested will be limited to the cohort of 2100 consented patients rising to 2500 patients by the end of recruitment in September 2024 who have consented to the PROMs and tissue study and to the data items required to answer the study aims. All patients are aged over 18 with a diagnosis of bowel cancer (ICD 10 code C18, 19 or C20) from 01/01/2018 onwards.
All episodes of data are requested 30 days prior diagnosis to 36 months after diagnosis (with the exception of NDRS HES which is requested 24 months prior to diagnosis and NDRS DIDs which is requested 36 months prior to diagnosis).
The University of Leeds is the research sponsor and the data controller responsible for ensuring that the data will only be processed for the purpose described above. The research is funded by Yorkshire Cancer Research with funding in place until September 2025. This programme of work will likely be extended until 2030 with subsequent funding requests to be submitted. The funder will have no ability to suppress or otherwise limit the publication of findings.
The lawful basis for processing personal data under the UK GDPR is:
Article 6(1)(e) - processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.
The lawful basis for processing special category data under the UK GDPR is:
Article 9(2)(j) - processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law which shall be proportionate to the aim pursued, respect the essence of the right to data protection and provide for suitable and specific measures to safeguard the fundamental rights and the interests of the data subject.
Processing is in the public interest as the funding from Yorkshire Cancer Research involved peer review and the study received ethical approval from the West Midlands Solihull Research Ethics Committee (17/WM/0374) both of which provide reassurance that the research is in the public interest. The study was also approved by the Health Research Authority and granted approval for inclusion in the National Institute for Health Research's portfolio of studies in December 2017 (Project ID 227673).
This processing is in the public interest because it adheres to the UK Policy Framework for Health and Social Care Research and aims to produce generalisable and publicly available information to inform future decisions over patients treatments or care.
University of Leeds are the joint data processor with Microsoft via the Leeds Analytic Secure Environment for Research (LASER) at the University of Leeds where data will be processed and stored. Microsoft Limited provides IT hosting services and IT back up services to the University of Leeds and will store copies of the data as contracted by the University of Leeds.
Members of the project steering group include individuals from Nuffield Department of Population Health at the University of Oxford and Leeds Teaching Hospitals NHS Trust. The individuals act only in an advisory capacity and will not be accessing the data. Data will only be accessed by employees and postgraduate students (PhD or MSc) registered with the University of Leeds. A student seeking access for their own purpose (eg: Masters project) is not covered under this permission.
Two patients and one carer are involved with the PROMs study and have been actively involved in discussing questionnaire content. They have provided feedback on the study protocol and documentation (cover and reminder letters, Information sheet and Consent form). They are members of the PROMs advisory group. In addition, the wider Yorkshire Cancer Research Bowel Cancer Improvement Programme (YCRBCIP) Project Group has a patient representative member who attends monthly meetings.
The national data opt-out does not apply where explicit consent has been obtained from the patient for the specific purpose.
Where individuals have opted out of disease registration by the National Disease Registration Service (NDRS), their data has been permanently removed from the registry and therefore will not be disseminated under this Data Sharing Agreement (DSA). https://digital.nhs.uk/ndrs/patients/opting-out
Expected Benefits:
The findings of this research programme are expected to inform best practice to improve the care, treatment, experience, and outcomes of bowel cancer patients across the Yorkshire and Humber region. The programme hopes to contribute to the knowledge and understanding of the reasons for differences in outcomes across the region. The PROMs data will enrich other study data and allow for an in-depth description of what life is really like for patients with bowel cancer at diagnosis and subsequently.
The use of the data could:
help the system to better understand the health and care needs of bowel cancer patients.
lead to the identification or improvement of treatments or interventions, or health and care system design to improve health and care outcomes or experience.
advance understanding of regional and national trends in health and social care needs.
inform planning health services and programmes, for example to improve equity of access, experience and outcomes.
provide a mechanism for checking the quality of care. This could include identifying areas of good practice to learn from, or areas of poorer practice which need to be addressed.
support knowledge creation or exploratory research (and the innovations and developments that might result from that exploratory work).
At present, the patient voice is not measured routinely as part of clinical practice, neglecting the impact of illness and treatment on the everyday lives of patients. This work aims to capture patient-reported information and feed it back to clinical teams to inform, and ultimately improve, outcomes. Looking to the future, such information can inform the integration of PROMs administration into clinical practice. The PROMs used in this study have been selected with input from experts in colorectal cancer and psychosocial care: patients, clinical nurse specialists and doctors. Although the length of the questionnaire would not be feasible to administer in everyday practice, information on which PROMs provide the most meaningful data will be obtained. In the future, risk-stratified follow-up may incorporate clinical indicators and key quality of life indicators to inform the best supportive care.
The funder, Yorkshire Cancer Research, are fully aware of the work undertaken within the programme and will be regularly updated on the results generated. Where it aligns with their priorities, actions can be taken to optimise the potential public benefits from the use of the data and to advertise the findings to a wider audience.
Outputs:
The study team will examine quality of life outcomes of bowel cancer patients across the region, identify areas where outcomes could be improved and develop educational programmes and interventions to address them. Regular updates will be provided to participating Hospital Trusts about the outcomes of the patients they treat.
The expected outputs include:
Reports sent to the MDTs across Yorkshire and to Yorkshire Cancer Research (the funder) - annual reports plus ad hoc in-depth reports
Submissions to peer reviewed journals at least 1 each year
Presentations to the wider YCRBCIP team (monthly steering group and annual workstream events).
Presentations at appropriate colorectal cancer or PROMs conferences (annually at The Association of Coloproctology of Great Britain and Ireland ACPGBI in July) (UK national PROMS conference in June)
Publication of results on YCRBCIP website https://ycrbcip.leeds.ac.uk/
The outputs will only contain aggregated information with small numbers suppressed in line with the relevant disclosure rules for the dataset(s) from which the information was derived.
The outputs will be communicated to relevant recipients through the following dissemination channels:
Journals
Educational events open to clinical teams, patients and carers
Social media (through YCRBCIP, University of Leeds, Yorkshire Cancer Research)
Direct engagement with MDTs across the study region
Annual study event highlighting programme progress and key achievements
Presentations/posters at appropriate conferences such as The UK Patient Reported Outcome Measures (PROMs) Research Conference, Cancer Research UK Data-driven cancer research conference and The Association of Coloproctology of Great Britain and Ireland (ACPGBI) Annual Meeting.
Press/media engagement in response to publication of journal articles and/or other outputs
Reports given to Yorkshire Cancer Research to provide information on the outcomes of bowel cancer patients across Yorkshire, to inform their future activities
Target dates for production and dissemination of the outputs are from Spring 2024 onwards. The programme is currently funded until October 2025.
Processing:
The University of Leeds will transfer data to NHS England. The data will consist of identifying details (specifically NHS Number, Date of Birth, Study ID and date of consent) for the cohort to be linked with NHS England data.
NHS England will provide the relevant records from the routine datasets (National Cancer Registration Dataset, Hospital Episodes Statistics, National Radiotherapy Dataset, Systemic Anticancer Therapy Dataset, Diagnostic Imaging Dataset, Rapid Registration Dataset) to the University of Leeds. The data will contain no direct identifying data items but will contain a unique study ID which can be used to link the data with other record level data already held by the research team. The data will not be transferred to any other location.
The disseminated data will be stored within the Leeds Analytic Secure Environment for Research (LASER), a secure Microsoft Azure cloud-based system provided by the University of Leeds. LASER meets Data Protection Toolkit (DSPT) regulations and ISO 27001 certifications.
LASER uses Microsoft Azure Backup Service to enable backup and restore of data from the Azure cloud.
The data will be accessed by members of the study analysis team via remote access, which comply with the following remote access obligations:
-Remote access will only be from secure locations situated within the territory of use (as further restricted elsewhere within the DSA if so done) stated within this DSA;
-Access controls granting users the minimum level of access required are in place;
-Remote access is only via secure connections (e.g., VPNs or secure protocols) to protect data;
-Multifactor authentication (MFA) is required for remote access;
-Device security, including up-to-date software and operating systems, antivirus software, and enabled firewalls are utilised for the remote access;
Access is restricted to employees and postgraduate students (PhD or MSc) registered with the University of Leeds who have authorisation from the Principal Investigator. All personnel accessing the data have been appropriately trained in data protection and confidentiality. It is prohibited to download or copy data to local devices.
The data will remain within LASER at all times. The data will not leave England/Wales at any time.
The data will be linked at person level. Patients are asked to consent to the collection of the PROMs data and collection of tissue samples within the same consent process. The PROMs data and the tissue data use the same study IDs allowing linkage without the need to access to any identifiable data.
The identifying details of consented patients will be stored in a separate environment to the linked dataset used for analysis. The environment storing identifiable data is only accessible to a limited number of the study team (not the same individuals with access to the linked pseudonymised data, where there will be no requirement and no attempt to reidentify individuals). Access to the identifiable data is via safe rooms on the University of Leeds campus and there is no access to external systems or the internet. Imports and exports are managed by the University of Leeds Institute for Data Analysis (LIDA) who manage the LASER platform. All imports and exports are verified, and an audit log kept.
Researchers from the University of Leeds will analyse the data for the purposes described above.

Objectives:
The Data Recipient will process linked cancer registration Live and Bladder Cancer (LABC) response data for an ethically approved research study into health related quality of life (HRQL) in bladder cancer patients from Yorkshire, Humber, South Tees and North Derbyshire. The study consists of consented cohort. Patients were recruited through hospitals in Yorkshire, South Tees and Chesterfield (Airedale, Barnsley, Bradford, Calderdale and Huddersfield, Chesterfield, Doncaster, Harrogate, Hull, Leeds, Mid Yorks, North Lincs, Rotherham, Sheffield, South Tees, York). However, they could be resident anywhere in England. This agreement seeks to extend the term of the DSA for 12 months.
This research aims to:
- Describe the health-related quality of life (HRQL) of people living with and beyond bladder cancer in Yorkshire, Humber, South Tees and North Derbyshire
- Gain a deeper understanding of the variation in outcomes
- To explore if and how HRQL is associated with or predicted by disease treatment and/or patient characteristics with a view to informing service delivery in order to better meet patient needs.
- Understand differences between newly diagnosed patients, those undergoing treatment and those having completed treatment for bladder cancer in Yorkshire and compare different treatments and healthcare providers
- Identify unmet needs.
The following pseudonymised datasets were previously disseminated by Public Health England to the University of Leeds.
NDRS Cancer Registrations
NDRS Linked HES APC
NDRS Linked HES Outpatient
NDRS National Radiotherapy Dataset (RTDS)
NDRS Systemic Anti-Cancer Therapy Dataset (SACT)
The national data opt-out does not apply where explicit consent has been obtained from the patient for the specific purpose.
Where individuals have opted out of disease registration by the National Disease Registration Service (NDRS), their data has been permanently removed from the registry and therefore will not be disseminated under this Data Sharing Agreement (DSA). https://digital.nhs.uk/ndrs/patients/opting-out
Yielded Benefits:
Expected Benefits:
The results will be made available to patients, their partners/spouses/carers, the funders, NHS, social care, voluntary sector organisations and other researchers through public and professional reporting. Comparative reports of service provider performance outcomes will also be produced. Reports will be disseminated through engagement with professional and patient representative bodies.
Knowledge of PROMs for patients with a new diagnosis of BC, those undergoing treatment for BC or following treatment will deliver several potential key benefits for patient care.
Firstly, it will be understood what matters most to patients. This will allow healthcare providers to develop strategies and to invest in pathways that address these concerns. Secondly, it will identify areas of excellent practice that can be highlighted for other services to learn from and will identify areas where more resources are needed.
Thirdly, changes over time following BC treatment will be understood. This knowledge will be used to better educate new patients about treatment choices and likely expectations. Finally, a BC PROMs tool will be developed that, hopefully, could be used nationally to improve the care of all patients with BC.
Outputs:
The LABC team and collaborators will continue to analyse the data from the Life and Bladder Cancer PROMs questionnaires.
Papers in progress include analysis of the longitudinal questionnaire data, decision regret and social difficulties.
Colleagues would access the LABC PROMs study dataset to explore how PROMs questionnaires could guide treatment choice.
It is anticipated that the work will be completed by 4th September 2024.
The following outputs are envisaged:
· Empirical knowledge of key clinical, socio-demographic and psychosocial factors that predict patients generic and cancer-specific HRQL. Findings will be disseminated through a series of reports, academic papers (open-access) and conference presentations, and all findings will be available on the dedicated study website.
· The electronic report and toolkit will be available to key stakeholders to provide detailed anonymised information. The toolkit will enable each NHS Trust, Clinical Commissioning Group and Strategic Clinical Network to visualise the results for their organisation and to compare them against the national average.
· A validated survey tool for the collection of health outcomes of BC survivors. This would be made available for use by other organisations and researchers (dependent upon appropriate conditions of use).
Processing:
The data was previously supplied by Public Health England (PHE) and the processing activities are below. Quality Health Ltd were involved at the start of the study but are no longer processing any survey data (and never had access to any NHS England data).
1. The NDRS had already obtained information on patients who have a diagnosis of bladder cancer (BC). This information is obtained in accordance with Section 251 of the Health and Care Act.
2. NDRS and the Study team wrote to the participating Trusts with information relating to the study along with a copy of the proposed PROM questionnaire and covering letter was sent out to survey participants. The Chief Executive and bladder cancer Multi-Disciplinary Team (MDT) lead was written to and their permission to survey people treated by their Trust was sought. Trusts were offered the chance to see the list of patients that were proposed to be surveyed. In this way Trusts were offered the chance to verify that the identified patients have had a diagnosis of BC and will have the opportunity to filter any patients where it is thought not appropriate that contact be made.
3. Once the lists had been agreed (after amendment by NDRS if required) they were sent to Quality Health Ltd (approved survey provider). Quality Health Ltd sent this list to NHS Digital, who cleaned the list, removing patients who have registered type 2 objections and deceased patients. The death checks were performed using the NHS Demographic Batch Service, operated by NHS Digital.
4. The updated list was sent to Quality Health Ltd, who obtained up-to-date addresses and prepared the survey packs for participants.
5. Quality Health Ltd contacted NHS England so that an additional death check can be performed immediately prior to sending the survey packs.
6. Quality Health Ltd sent out the survey packs. The questionnaire was sent out with a covering letter from the treating NHS Trusts Chief Executive and BC MDT lead, a summary PIS and a full version of the PIS, so that participants have more details about the study and instructions for how to complete the questionnaire online if they would prefer. The questionnaire had a unique study identification number but contained no other identifiable information in its uncompleted form. By completing the questionnaire, the participant is consenting to take part in the study.
7. The questionnaires were returned to Quality Health Ltd either in a freepost envelope, by completing the questionnaire online or over the telephone. If people did not wish to participate, they were advised to return the blank questionnaire or contact the free survey helpline to inform them that they do not wish to complete the questionnaire.
8. The unique questionnaire identification number was linked back to the original patient list in order to keep track of which people have returned the questionnaire or have opted out (by returning the questionnaire blank or phoning the dedicated questionnaire helpline). One reminder will be sent (with additional death checks performed).
9. The questionnaire data was cleaned and anonymised by Quality Health Ltd to remove any identifying information.
10. The cleaned data was sent back to NDRS using a secure transfer mechanism. NDRS linked the questionnaire data back to the necessary patient, disease and treatment information contained within the cancer systems.
11. NDRS forwarded the dataset of pseudonymised questionnaire responses, disease and treatment information alongside a study identification number (only) to the study team in Leeds for analysis. The data will be stored within the secure environment at the Leeds Institute for Data Analytics (LIDA).
The pseudonymised data will be stored within the Leeds Analytic Secure Environment for Research (LASER), a secure Microsoft Azure cloud-based system provided by the University of Leeds. LASER meets Data Protection Toolkit (DSPT) regulations and ISO 27001 certifications.
LASER uses Microsoft Azure Backup Service to enable backup and restore of data from the Azure cloud.
The data will be accessed by members of the study analysis team at the University of Leeds via remote access, which comply with the following remote access obligations:
-Remote access will only be from secure locations situated within the territory of use (as further restricted elsewhere within the DSA if so done) stated within this DSA;
-Access controls granting users the minimum level of access required are in place;
-Remote access is only via secure connections (e.g., VPNs or secure protocols) to protect data;
-Multifactor authentication (MFA) is required for remote access;
-Device security, including up-to-date software and operating systems, antivirus software, and enabled firewalls are utilised for the remote access;
The Data will not be linked with any other data
There will be no requirement and no attempt to reidentify individuals when using the Data.
Analysts/researchers from the University of Leeds will process/analyse the Data for the purposes described above. All personnel accessing the Data have been appropriately trained in data protection and confidentiality.
Understanding the outcomes of patients with cirrhosis and hepatocellular carcinoma (HCC) in the England ( ODR1718_432 ) — DARS-NIC-656823-G0Q2C
Type of data: information not disclosed for TRE projects

Legal basis: Health and Social Care Act 2012 s261(2)(a)
Purposes: No (Academic)

Objectives:
Cirrhosis is a major risk factor for the development of hepatocellular carcinoma (HCC). Diagnosis and treatment of HCC in the setting of cirrhosis is complex and depends not only of the stage of cancer but also on the severity of underlying cirrhosis and other patient factors
Objectives:
1. Which baseline factors determine treatment allocation and overall survival in HCC?
2. How is HCC treatment allocation associated with overall survival and decompensation of cirrhosis?
3. What is the nature of regional variation in baseline factors and treatment allocation in HCC?
Project aim include hypotheses if relevant
To exploit routine health data to investigate how variation in baseline characteristics at HCC diagnosis and geographical location influence treatment allocation and clinical outcomes. In addition to overall survival, the rate of progression of underlying liver disease will also be investigated, to understand the competing mortality of HCC and cirrhosis.
Expected Benefits:
We hope that the project will inform future research and ongoing work within the HCC-UK/ NCRAS partnership on understanding variation in access to treatments and clinical trials, as well as cost-effectiveness analyses. An understanding of the natural history of cirrhosis in the setting of HCC provided by our analysis will inform the planning of surveillance programmes for HCC in cirrhosis. These analyses have the potential to identify variations in clinical practice and therefore to improve future resource allocation and clinical outcomes
Outputs:
The study team expect that the development of the Baveno stage SOP will be applicable to a wide number of future population-based studies that require an assessment of cirrhosis severity.
We expect to publish these findings in peer reviewed scientific journals and present at scientific conferences. The two main publications include the description of regional variation in HCC treatment and survival (adjusted for cirrhosis severity) and the competing risk analysis of HCC treatment outcomes.
Processing:
HCC will be defined using ICD-10 code C22.0. The cohort of patients will be defined by those patients with a new diagnosis of HCC between 01/01/2007 and 31/12/2016. This dataset will be linked to the Hospital Episode Statistics (HES) database. A HES extract will be obtained containing information on Finished Consultant Episodes (FCEs) for those individuals in the HCC cohort. This extract period will start from 5 years prior to the HCC diagnosis date and continue until death or the end of the study period.
A focussed HES extract will be retrieved and analysed in order to achieve the specific aims of the study, as described in the following sections:
Which baseline factors determine treatment allocation and overall survival in HCC?
In order to assess the baseline factors, the following non-identifiable data will be extracted:
Age at diagnosis in 5 year age bands (from Cancer Registry)
Sex (from Cancer Registry)
Ethnic category and broad ethnic group (from Inpatient HES).
This is required because it may be associated with some aetiologies of liver disease, including viral hepatitis which is more common in migrant populations.
Cancer stage (using Best registry stage at diagnosis of the tumour from Cancer Registry)
There is an expectation that the data quality of HCC cancer stage is poor due missing values, but this will be included to comparison purposes.
Medical co-morbidities
Diagnostic codes related to medical comorbidities contained within Inpatient HES will be extracted, along with the time interval from HCC diagnosis date to the start of the associated episode. In addition to Inpatient HES Charlson Index, codes for individual co-morbidities will be extracted because they impact the progression of liver disease.
Aetiology of underlying liver disease
Specific diagnostic codes relating to different liver disease aetiologies will be extracted from episodes contained within the total study period.
Presence of cirrhosis at HCC diagnosis
Specific diagnostic and procedure codes relating to cirrhosis or its complications (ascites, oesophageal or gastric varices and hepatic encephalopathy) will be extracted from episodes within the total study period. The time interval from HCC diagnosis to the start of the associated episode will be extracted. If these codes appear at any point during the study, it will be assumed that the HCC occurred in the background of cirrhosis.
Cirrhosis stage at HCC diagnosis
Diagnosis and procedure codes specific to cirrhosis-related complications (along with the time interval from HCC diagnosis to the start of the associated episode) will be extracted from Inpatient HES. Analysing a time interval from 5 years before HCC diagnosis to 3 months after will enable the calculation of the baseline Baveno stage. We expect that this algorithm will generate a new SOP for the classification of liver disease severity from Inpatient HES for use by others:
Stage 1: No varices, no ascites
Stage 2: Varices, no ascites
Stage 3: Ascites +/- varices
Stage 4: Bleeding +/- ascites
Overall survival in relation to these baseline factors will be established by extracting the time interval from HCC diagnosis date to death from the Cancer Registry. The certified cause of death and underlying cause of death will be extracted from the Cancer Registry.
How is HCC treatment allocation associated with overall survival and decompensation of cirrhosis?
An Inpatient HES extract spanning the total study period will be used to identify specific HCC-related treatments. The procedure codes and time interval from HCC diagnosis to the episode containing the treatment will be recorded. The site code of treatment will also be collected.
In order to assess the use of sorafenib, data held within the cancer registry (AV_treatment) and within the Systemic Anti-Cancer Therapy Data Set (SACT) will be analysed. Sorafenib will be searched within the raw regimen data item in SACT, along with the time interval from HCC diagnosis until the start of the drug regimen. The organisation code of provider will be recorded to identify the treating centre.
Clinical outcomes will be determined including:
Overall survival
Survival post-treatment will be inferred from the time interval from HCC diagnosis date to death and the interval from HCC diagnosis to each HCC treatment
Rate of decompensation of cirrhosis following different treatments
Diagnosis and procedure codes specific to complications of cirrhosis which occur after the HCC diagnosis will be extracted, along with the time interval from HCC diagnosis date to the start of the associated episode. An updated cirrhosis stage will be calculated using the new Baveno stage SOP.
What is the nature of regional variation in baseline factors and treatment allocation in HCC?
Baseline factors at HCC diagnosis (in collaboration with the University of Liverpool)
The broader geographical area and index of multiple deprivation (IMD) quintiles will be extracted from Inpatient HES. The baseline factors for each area will be assessed using the data items extracted in Section 1.
HCC Treatment allocation at different centres
The code of the NHS Trust in which the HCC treatment took place (site code of treatment) will be extracted from the Inpatient HES episode associated with the specific HCC treatment. This is a necessary additional data item to a patients broader geographical area because it will also demonstrate where patients actually receive their HCC treatment. The variation in treatment allocation at different specialist centres can then be established and this will be correlated with the baseline factors.
c. Apply the described variation in baseline factors and treatment allocation to understand regional differences in survival (in collaboration with the University of Liverpool)
The factors described above will be used to identify predictors of regional variation in survival that may relate for instance to stage of liver disease at presentation or differences in treatment allocation.
Statistical Analysis
For each of the study sections, the following statistical analysis will be performed:
This analysis will be informed by the Cohort Overview, undertaken by the HCC-UK partners in Bristol (AB), which will describe the patient characteristics. Descriptive statistics will be used to characterise the baseline factors of the HCC cohort, assessing for significant associations between variables.
A two-state disease model (dead or alive) will be used for standard survival analysis: univariate analysis will be performed using the Kaplan-Meier method, with patients stratified by the baseline factors of interest such as cirrhosis stage. A Cox proportional hazards regression will be used to calculate a hazard ratio for the baseline determinants of overall survival.
a. Survival analysis will be performed using the Kaplan-Meier method, stratified by treatment allocation. Survival between the groups will be compared using the log-rank test. Patient numbers are expected to be large enough to allow further stratification by baseline factors of interest, such as liver disease aetiology.
b. The rate of decompensation of cirrhosis following different HCC treatments will be determined by calculating the risk of hospital readmission with complications of decompensated cirrhosis within 30 days. The baseline characteristics of those patients who have decompensation events will be compared using multivariate logistic regression in order to identify predictive factors.
A competing risk analysis will be performed using a cumulative incidence function (CIF) to describe the rate of cirrhosis decompensation events admission following different HCC treatments. The clinical states used in a multi-state disease model will be: compensated cirrhosis, decompensated cirrhosis, death related to HCC and death related to liver disease (from death certification).
a. The baseline factors will be cross-tabulated with broader geographical area and tested for significant associations. Analysis performed by HCC-UK partners in Liverpool (VK, TC, DP) will lead to an estimate of the median overall survival for each broader geographical area and linked IMD and travel time to destination. Significant differences in median survival between areas and the association with IMD quintile will be tested and adjusted for the variation in baseline factors.
b. For each centre treating patients with HCC, the proportion of patients receiving different HCC modality will be calculated. The statistical significance of any variation in treatment allocation between centres will be tested and adjusted for baseline characteristics.
c. Baseline factors and treatment allocation will be used in Cox proportional hazard models to investigate the potential differences in survival.

Objectives:
University of Leeds requires access to NHS England data for the purpose of the following research project:
Is the survival of teenagers and young adults with cancer associated with the dose and intensity of chemotherapy that they receive?
The following is a summary of the aims of the research project provided by University of Leeds:
This is a study to investigate whether the dose intensity of systemic anticancer agents (chemotherapy) received by Teenagers and Young Adults (TYA) with cancer impacts on their survival. It will also determine whether any factors exist which influence a patients ability to receive the ideal amount of chemotherapy.
This study will use data from NCRAS to determine whether the amount of chemotherapy received by TYA cancer patients affects their length of life. The specific objectives are to:
1. To obtain detailed chemotherapy treatment history for all patients aged 12-29 years old treated with chemotherapy for chemo-sensitive cancers in the UK using existing linkage between the Systemic Anti-Cancer Therapy (SACT) dataset and the National Cancer Registry.
2. Analyse this data to investigate whether the dose and intensity of chemotherapy administered to patients affect one-year and three-year survival.
3. To investigate patient factors which act as barriers to receiving optimal treatment delivery. Variables include; gender, age, ethnicity, the distance that the patient lives from the treatment centre, stage at diagnosis, tumour site, socioeconomic background and treatment centre (i.e. whether specialist TYA unit or paediatric or adult unit).
4. To explore the SACT dataset for data relating to treatment toxicity, for example, dose modification and dose time delay, and determine whether the level of toxicity experienced has an impact on the total dose of chemotherapy received and patient outcome (in terms of one and three-year survival).
The following NHS England data will be accessed:
Cancer Registration
Systemic Anti-Cancer Therapy Data Set (SACT)
The level of the data will be pseudonymised.
The data will be minimised as follows:
Limited to data between April 1st 2014 2020. For each individual patient, data will only be provided from patient ages between 12 to 29 years old at diagnosis.
Limited to conditions relevant to the study identified by specific ICD or OPCS codes;
o ICD10 codes C00 C97, D32-D33
Limited to the following geographic area(s): England
The University of Leeds is the controller as the organisation responsible for ensuring that the data will only be processed for the purpose described above.
The lawful basis for processing personal data under the UK GDPR is:
Article 6(1)(e) - processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.
The lawful basis for processing special category data under the UK GDPR is:
Article 9(2)(j) - processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law which shall be proportionate to the aim pursued, respect the essence of the right to data protection and provide for suitable and specific measures to safeguard the fundamental rights and the interests of the data subject.
This processing is in the public interest because the findings are important to TYA cancer patients and have the potential to impact survival rates and the quality of survivorship. In addition, emerging findings from this research outline ways in which this data could be improved, which would be of benefit to the public.
The funding is provided by the National Institute for Health and Care Research (NIHR). The funding is specifically for the study described. Funding is in place until 31/12/2023.
Funding to continue the work described will be sought on an ongoing basis.
The funder(s) will have no ability to suppress or otherwise limit the publication of findings.
Microsoft Azure (LASER) provides IT hosting services to University of Leeds and will store the data as contracted by the University of Leeds.
Data will be accessed by a PhD student employed by University of Leeds and a clinical trainee working under honorary contract. The individuals have completed mandatory data protection and confidentiality training and is subject to University of Leedss policies on data protection and confidentiality. The individuals accessing the data will do so under the supervision of a substantive employee of University of Leeds. University of Leeds would be responsible and liable for any work carried out by the study team. The study team would only work on the data for the purposes described in this Agreement.
The data controller engages members of the public and participants through the presentations of the study results. Feedback from families and cancer survivors have shown that they are hugely grateful for the Register and research carried out on their behalf. Those attending these presentations felt that they had been sufficiently informed about the research and are comfortable and supportive of the need to collect and process this data without informed consent. The study team have carried out local and national PPI workshops which have enabled the study team to ensure that the research questions are important and relevant to patients and their families/ carers.
In line with the National data opt-out policy, opt-outs are not applied because the data is not Confidential Patient Information as defined in section 251(10) and (11) of the National Health Service Act 2006
Where individuals have opted out of disease registration by the National Disease Registration Service (NDRS), their data has been permanently removed from the registry and therefore will not be disseminated under this Data Sharing Agreement (DSA). https://digital.nhs.uk/ndrs/patients/opting-out
Yielded Benefits:
Data for this study has previously been shared when the data were controlled and managed by Public Health England (PHE). Due to COVID delays in data dissemination the study team is now just reaching the point of producing outputs from the data and so expect the benefits to be yielded shortly.
Expected Benefits:
There is evidence being gathered that there may be a case for de-escalation trials in some patient groups. This may have potential to reduce effects caused through chemotherapy, reducing the treatment burden on the NHS and improving quality of life for the patients.
The outcome of this project could lead to changes in the recommended management of these patients and improve patient outcomes. The hope is that where dose matters for outcomes, identification of barriers to patients receiving optimal chemotherapy can guide NHS interventions to optimise the treatment that patients receive.
The study team are also able to access whether patients in this age category are achieving optimum doses of chemotherapy within real world NHS care.
This study will also determine how useful this data is for use in the Teenage and Young Adult Cancer population and any improvements that could be made.
The research team work with both local and national Patient and Public Involvement (PPI) groups. These groups ensure that the research questions being asked are important and relevant to the target patient groups and aid dissemination. The study team have carried out national PPI workshops alongside the Teenage and Young Adult (TYAC)/ Children's Cancer and Leukaemia Group (CCLG) charities and organisations such as UseMyData with the aim of improving public confidence in the use of children and young adults cancer data for research purposes, hoping to reduce the number of opt outs. This work has been written up for publication. If the results were felt to warrant attention the study team will disseminate these results via these charities.
In the coming months the study team are working alongside the local Childrens cancer charity Candlelighters at a University open day showcasing the work to the public.
The work will also be disseminated internationally at relevant conferences such as SIOP or the AYA international congress.
Outputs:
The expected outputs of the processing will be:
Three publications dates are estimated and may be subject to slight changes.
- July 2023 - first publication submitted focusing national treatment of germ cell tumours.
- Dec 2023 - second publication submitted focusing on bone tumours.
- January 2024 - third publication focusing on the comparison of what data is available at a national and regional level (comparing data [but not sharing or linking data] from this agreement with a separate dataset held by the research team, the Yorkshire Specialist Register of Cancer in Children and Young People).
An abstract was presented at the International Data Linkage conference on use of this data in the TYA population in September 2022.
An abstract was presented at advances in Ewings sarcoma conference in October 2022.
The outputs will not contain NHS England data and will only contain aggregated information with small numbers suppressed as appropriate in line with the relevant disclosure rules for the dataset(s) from which the information was derived.
The outputs will be communicated to relevant recipients through the following dissemination channels: research journals, conferences, presentations at relevant organisational meetings, social media (e.g. twitter).
Outputs generated by the data thus far;
Presentation of an abstract at the International Data Linkage conference in Edinburgh in September 2022.
Presentation of an abstract at the International SIOP conference in Barcelona in September 2022. This work was in collaboration with DATA-CAN and the CCLG exploring the views of young people and carers of young people with cancer regarding the use of medical data for research. This work is currently being written up for publication.
In October 2022 presentation of an abstract at the Advances in Ewing Sarcoma Research conference which won a prize for best poster.
Processing:
No data will flow to NHS England for the purposes of this Agreement.
NHS England provided the relevant records from the Cancer Registration and SACT datasets to the University of Leeds. The data contained no direct identifying data items but contained a unique person ID which can be used to link the data with other record level data already held by the recipient.
The data will not be transferred to any other location.
All data is held on a secure, encrypted Microsoft Azure cloud platform (LASER) at the University of Leeds, (see https://lida-data-analytics-team.github.io/laserdocs/docs/laser_info/laser.html).
In 2023/2024 there is a planned migration from Microsoft Azure cloud platform (LASER) at the University of Leeds to AIMES trusted research environment (TRE) an encrypted private cloud service. At this point the following physical precautions will be in place to protect the data and the University of Leeds will submit an amendment to NHS England to reflect the transfer of data processor.
The University of Leeds currently stores data and all daily backups on the Cloud provided by Microsoft Azure servers. Backups are for a 12-month period. The backup retention policy can be found at https://lida-data-analytics-team.github.io/laserdocs/docs/laser_info/backups.html
The data will be accessed by authorised personnel via remote access. The data will remain on the servers at Microsoft data servers at all times (until the migration to AIMES). All users of the Microsoft Azure cloud platform (LASER) system must sign a confidentiality agreement, which includes stipulating that security and confidentiality must be maintained. Certain breaches of security could lead to disciplinary and legal action being taken.
Personnel are prohibited from downloading or copying data to local devices.
The data will not leave England/Wales at any time.
Access is restricted to employees or agents of University of Leeds and an academic clinical trainee working under an honorary contract who have authorisation from the Principal Investigator. All persons accessing the data will be required to complete the Universitys Information Governance training.
Only those essential members of staff who work on the Register and require direct access to the database are granted authorisation from the Principal Investigator.
No NHS Digital data will be transferred outside of the University of Leeds or shared with any third-party individual or organisation.
This data will not be linked to any other data sources outside the scope of this agreement. The data will be analysed as a complete dataset.
There will be no requirement and no attempt to reidentify individuals when using the data.
Researchers from the University of Leeds will analyse the data for the purposes described above. Data will only be used for the purposes described in this Agreement.
The data requested in this agreement is not considered confidential under the Health and Social Care Act 2012 and therefore is not subject to a duty of confidence, as such the national data opt-out is not applied.
Where individuals have opted out of disease registration by the National Disease Registration Service (NDRS), their data has been permanently removed from the registry and therefore will not be disseminated under this Data Sharing Agreement (DSA). https://digital.nhs.uk/ndrs/patients/opting-out

Objectives:
The following summarises the purpose of processing previously approved by the Public Health England (PHE) Office for Data Release (ODR):
This application is to link the data collected by LAPCD as part of the survey of men with prostate cancer, with routine data from PHE. With the objectives:
1) ensure maximum exploitation of LAPCD survey data through linkage with existing health datasets;
2) identify factors associated with good/poor QoL outcomes to inform future service delivery.
The request relates to data linkage (workstream 3 of the protocol) which will then be fed into benchmarking (workstream 4) and health economics (workstream 5). This will utilise several routine datasets to maximise the amount of clinical and treatment information available. Some of these datasets have already been linked through work done by NCRS and the National Cancer Intelligence Network (NCIN).
The University of Leeds has now ceased processing data for this purpose, however, wishes to retain it as they intend to submit a request to re-use the data for a new purpose.
Processing is permitted to support the secure retention of the data only.
Yielded Benefits:
The LAPCD study collected data on quality of life from mean with prostate cancer across the UK. In summary, the study team published 15 peer-reviewed articles, sent reports to each clinical team across the UK and published data on the Cancer Stats website. See https://www.lifeafterprostatecancerdiagnosis.com/academic-publications-and-toolkits/ for details. The data were also used by Movember to create the Men like me webtool (https://truenorth.movember.com/en-gb/men-like-me) to help men understand whats normal after treatment for prostate cancer. Specific benefits include: Helping the system to better understand the health and care needs of populations tailored reports were sent to each NHS Trust or Health Board across the UK detailing the survey results for the men diagnosed in that Trust/Board. This allowed clinicians to see what issues and difficulties men were facing after their treatment and also to compare with the country as a whole. Advancing understanding of regional and national trends in health and social care needs work was published examining regional variations in outcomes across the UK and highlighted areas with higher and lower quality of life and functional issues. Better informing those planning health services and programmes, for example, initiatives to improve equity of access, experience and outcomes in the short or long term several publications highlighted areas where improved access to services was required. For example, results showed that half of men were not offered services for sexual dysfunction and half of those who were offered did not find it helped. Another example was men taking hormone therapy reporting high levels of side-effects and needing increased support to deal with weight gain, hot flushes and depression. Advancing understanding of the needs of carers supporting family members interviews were undertaken with partners of men with prostate cancer and analysis gave insights into the issues they faced and how they felt they could be better supported.

Liaison psychiatry (LP) involves the provision of mental health services in non-psychiatric settings, in this case in general hospitals. Liaison services exist because there are higher rates of most mental health problems in general hospitals than there are in the general population. The two main questions asked of them are: do they improve outcomes for the people referred to them and if so can they do so in a cost-effective way? It has even been claimed that LP saves the NHS money by reducing inappropriate use of expensive general hospital stays and treatment for people who are best helped in other ways. The challenge in answering these questions is that liaison services vary greatly in how they are set up, in the sort of referrals they see, and in how they deliver care. Liaison psychiatry for the elderly does not cover the same ground as that for working age adults. So asking whether liaison services are cost effective is not like asking whether a cardiac surgery service is cost-effective but more like (on a smaller scale) asking if general practice is.
A major challenge in assessing the cost-effectiveness of liaison psychiatry services resides in the variability in their case-mix and also in how they are configured. There is also considerable diversity in external (demographic and other service) factors that influence outcomes for liaison psychiatry. LP-MAESTRO is a project at the University of Leeds, which has been funded by the National Institute for Health Research and Health Services and Delivery Research (NIHR HS&DR) as part of a commissioned call (13/58 Organisation, quality and cost-effectiveness of psychiatric liaison services in acute settings), to develop an approach based upon economic modelling and using routinely-collected NHS data, that allows the University to evaluate the cost-effectiveness and efficiency of particular configurations of liaison psychiatry service for specified target populations.
The overall aim of LP-MAESTRO is to evaluate the cost-effectiveness and efficiency of particular configurations of liaison psychiatry service for specified target populations. To do this, an innovative approach based upon linking routinely collected patient-level data and using economic modelling with the resulting aggregated data will be developed and evaluated.
Under the General Data Protection Regulation (GDPR), a legal basis is required for processing of personal data. The legal basis under which data is processed within the project Liaison Psychiatry Measurement and Evaluation of Service Types, Referral Patterns and Outcomes (LP-MAESTRO) is:
Article 6 (1) (e) processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller;
Processing of data concerning health (and other special categories of data) requires the fulfilment of an additional condition under GDPR. The specific condition fulfilled by the processing of such data within LP-MAESTRO is:
Article 9 (2) (j) processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law which shall be proportionate to the aim pursued, respect the essence of the right to data protection and provide for suitable and specific measures to safeguard the fundamental rights and the interests of the data subject.
The overall aim is to evaluate the cost-effectiveness and efficiency of particular configurations of liaison psychiatry service for specified target populations. The purposes described in this agreement amount to a sub-study of the LP-MAESTRO project.
LP-MAESTRO is a collaboration between academics and practitioners at the University of Leeds, University of Manchester and Imperial College, Peninsula Schools of Medicine & Dentistry, The Centre for Mental Health, The Royal College of Psychiatrists and Leeds York Partnership Foundation Trust. Leeds University are the Data Controllers for this work described under this agreement - the other organisations noted in the collaboration do not have any influence over the outputs generated. The other collaborators listed provide contributions to the main LP-MAESTRO project DARS-NIC-77953-C4M3T-v1.3. These organisations have no direct role in the processing of the data received under this agreement for the sub-study of LP-MAESTRO
Leeds University will have rights to the data disseminated for this project to relate to the processing of the data. Only staff at the University of Leeds will be involved in the processing of the data received from NHS Digital.
LP-MAESTRO has three work packages as a whole. The current work as described in this agreement was originally intended as pre-protocol preparation for Work Stream 2 of the LP-MAESTRO Project. However, delays in data release mean it has been subsumed into that work stream, demonstrating the value but also the significant drawbacks of using single datasets like HES to attempt to evaluate liaison services.
The work packages within this agreement do not directly relate to the work being undertaken in Workstream 2 which has its own agreement in place - DARS-NIC-77953-C4M3T-v1.3
Workstream 2 Phase 1 (WS2P1) focuses on 11 acute hospitals in England that were identified within Workstream 1 of LP-MAESTRO and the Liaison Psychiatry Survey England 2015 as not having a Liaison Psychiatry service.
Workstream 2 Phase 2 (WSP21) focuses on hospitals in England that were identified within Workstream 1 of LP-MAESTRO and the Liaison Psychiatry Survey England 2015 as having a particular configuration of Liaison Psychiatry service. To enable pathways to be constructed for patients attending these hospitals that consider the interaction of patients with the Liaison Psychiatry services in these hospitals, data is additionally
required from the NHS trusts that run these services.
The work-packages in this agreement relate to the preparation for work-stream 2.
Record-level data supplied under this agreement will only be held, processed and stored by the University of Leeds. Other collaborators and partners mentioned above will only have access to aggregated outputs with small numbers suppressed in line with the HES analysis guide.
The data requested under this agreement includes the Hospital Episode Statistics (HES) inpatient episodes for patients (aged 16 years or over) who have attended two specific hospitals in Birmingham over a 5 year period (2007-2011):
o City Hospital Birmingham
o Queen Elizabeth Hospital Birmingham (University Hospitals)
For each episode, the following data items were requested and have been received:
o Patient pseudonym
o Duration of spell
o Diagnostic codes
o Treatment speciality
o Provider code
o Date of admission
o Method of admission
The episodes in the two hospitals have been compared in terms of:
o Length of spell
o Readmission within 12 months from discharge
Figures have been compared (for different patient subgroups) across the hospitals using standard statistical methods.
Special statistical techniques (multilevel negative binomial model) were used to deal with the two challenges:
- [1] length of stay are very unevenly distributed with some people staying only one day and some staying many weeks,
- [2] a single patient may account for several inpatient episodes, complicating interpretation.
This has enabled the estimation of whole hospital effects over time (for the five-year study period) and comparison between hospitals. The data have allowed the study to answer an important question about liaison psychiatry services and their effect on lengths of stay in a general hospital; this was a key part of the logic of the project and is therefore useful to the overall research programme. The analysis indicated a number of factors of relevance in understanding the project as a whole: the inaccuracy of mental health coding in HES (mainly under-reporting); striking differences between hospitals in terms of coding rates and of lengths of inpatient stay (LOS); a time trend for LOS with a linear reduction over a 5 year period this pattern is extremely important in understanding claims that liaison services reduce hospital lengths of stay; lack of an obvious effect of introduction of a Rapid Assessment Interface and Discharge (RAID) liaison psychiatry service on hospital-wide lengths of stay once the background trend is taken into account.
Data will not be used for any other purpose that is not defined in this agreement. No attempts will be made to re identify individuals with data provided under this agreement.
There will be no data linkage undertaken with NHS Digital data provided under this agreement that is not already noted in the agreement.
Yielded Benefits:
The data so far have allowed the study to answer an important question about liaison psychiatry services and their effect on lengths of stay in a general hospital; this was a key part of the logic of the project and is therefore useful to the overall research programme. Preliminary results have been presented at a Rapid Assessment, Intervention and Discharge (RAID) network conference in Chester in April 2017. The purpose of this updated application is to extend the data sharing agreement relating to this data for a further year (until 30/06/2020) to enable analysis to be finalised and prepared for publication.
Expected Benefits:
The results of this application will be used to determine the cost-effectiveness and efficiency of a particular liaison psychiatry service configuration. They are planned for later this year with two groups in Royal College of Psychiatrists and Centre for Mental Health.
Benefits include:
- Illustration of a value of a particular approach (interrupted time series - which is analysis using a quantitative, statistical method in which multiple (sometimes as many as 40 or 50) repeated observations are made at regular intervals before and after intervention) in evaluating impact of new services.
- Recommendation to commissioners on an approach to evaluating services using routine data.
Project collaborators in Royal College of Psychiatrists and the Centre for Mental Health are conducting interviews and focus groups with service commissioners, to identify the best form and content for materials generated by the project when the aim of those materials is to inform decision-making. These are planned for later this year with two groups in Royal College of Psychiatrists and Centre for Mental Health.
In Work Stream 3 of LP-MAESTRO (a further stage) the study will then generate those materials. The impact on health and social care of any one piece of research is necessarily limited by the impact of competing claims including policy imperatives that are based upon values rather than evidence. Nonetheless, this work should be influential because it is only the second attempt in the UK to evaluate the effect of liaison psychiatry services on acute hospital lengths of stay.
The study has developed groups of committed and informed members of the public who are all people with experience of long term physical illness and awareness of mental health issues. They are drawn from patient organisations such as Diabetes UK, Breatheasy and Heartline. and have experience of membership of steering committees, development of participant information resources, research websites, patient interventions and dissemination of research findings. These organisations provide representation for patients with physical health problems. Such patients may experience mental health problems during the course of a hospital admission and require care from a liaison psychiatry service.
Outputs:
The data so far have allowed the study to answer an important question about liaison psychiatry services and their effect on lengths of stay in a general hospital; this was a key part of the logic of the project and is therefore useful to the overall research programme. Preliminary results have been presented at a Rapid Assessment, Intervention and Discharge (RAID) network conference in Chester in April 2017, but the main dissemination activity is as below.
There are a number of audiences for the outputs of this research clinical service providers in liaison psychiatry and general hospital managers, both groups who wish to plan the most effective provision of psychiatric services; commissioners of healthcare in Clinical Commissioning Groups (CCG's) and their associated Commissioning Support Units; data scientists who are interested in the challenges of data-linkage and the information it can yield.
For clinicians and academics in liaison psychiatry and health services researchers the study will produce standard academic publications the NIHR report, papers and conference presentations. The study will disseminate these outputs via academic and clinical publications . The Centre for Mental Health will produce two publications related to the findings these are disseminated widely to non-academic audiences.
For non-academics in management the study will produce a synopsis of findings. These will be prepared in paper format and in the form of mini-tutorials that the study will make available by links to the website.
The study will signpost these outputs through articles in newsletters and via professional discussion forums such as the liaison psychiatry jisc-mail group (JISC-Mail provides email discussion lists for education and research) and economic associations mailing lists.
To ensure that the research reaches as wide an audience as possible the study plan to develop a series of interactive webinars that will be free to view. After the live webinar, the presentation recording will be available free to download, hosted on the university leading the research and the project webpage and will be publicised via mailing lists and social media such as Twitter.
At the end of the project the study will hold a specialist conference the aim of which will be to review current knowledge in the underpinning areas of whole-service evaluations of cost-effectives as relevant to liaison services and the use of data linkage to evaluate services that cut across sectors, and the specific content area - what the study have learned about cost-effectiveness in liaison psychiatry.
An Academic paper to a health services research or mental health journal will be submitted by the end of 2017 (The previous version of this agreement requested an extension to the agreement end date in order to facilitate the required analysis and enable generation of research outputs. The date for this output has not changed from the previous version of the agreement).
Use of the data will be included in the final report of main project. The end date of the project was previously 31st December 2017. However, a request is currently under consideration by the funder of the main project (NIHR HS&DR) to extend the project for a further 12 months (30th June 2020).
A discussion paper will be produced for mental health service commissioners.
The Birmingham findings will be presented as described in this section, as part of the wider LP MAESTRO findings
A paper published in a medical academic journal will be read mainly by clinicians in liaison psychiatry and by applied health researchers, and this will influence national debates about the nature of liaison provision, which take place in professional forums such as the Royal College of Psychiatrists. Mental Health Service commissioners influence services by the way they fund structures and require certain outcomes; the project will inform the approach to service evaluation when services are commissioned with the aim of reducing hospital lengths of stay. The project has influenced the overall approach in LP-MAESTRO by indicating the need to have patient-level data to evaluate the impact of liaison services.
All outputs will consist of aggregate data with small numbers suppressed in line with the HES Analysis Guide. No record level data will be shared with any third party.
Processing:
All organisations party to this agreement must comply with the Data Sharing Framework Contract requirements, including those regarding the use (and purposes of that use) by Personnel (as defined within the Data Sharing Framework Contract ie: employees, agents and contractors of the Data Recipient who may have access to that data.
Data is stored securely in an infrastructure provided by the Leeds Institute for Clinical Trials Research (LICTR). Access to the data is restricted to specific members of the research team authorised by the Principal Investigator and granted access by the administrator(s) of the LICTR infrastructure.
Data relating to this project is backed up to the University of Leeds Central Backup Service on University of Leeds owned and managed servers, located within University of Leeds managed data centres. For disaster recovery purposes this data is mirrored to University of Leeds owned and managed servers located in the TFTA Data Centre at University of York. At no point does the University of York or its staff have access to view or process this data. UoY are renting secure rack space for servers to the University of Leeds. The servers themselves, their storage, access and management are all maintained exclusively by UoL staff. Therefore University of York are not considered to be Data Processors.
Data was initially processed to derive the analytical variables of interest. Special statistical techniques (multilevel negative binomial model) were then used to deal with the two challenges: [1] length of stay are very unevenly distributed with some people staying only one day and some staying many weeks, [2] a single patient may account for several inpatient episodes, complicating interpretation. This has enabled the estimation of whole hospital effects over time (for the five-year study period) and comparison between hospitals. The data supplied has been (and will be) solely used for the purpose outlined within this agreement. Data will be securely destroyed prior to the end date of the data sharing agreement (subject to any further extensions).
This data captured the admissions details for two specific hospitals in Birmingham over a 5 year period to facilitate their comparison.

Objectives:
Most people now understand the need for a cost-effective NHS, but seek reassurance that this will not reduce the standard of care. This is particularly true of older people, who are the group most likely to be affected by this research.
Total joint replacement provides considerable improvement in quality of life to people suffering with severe joint damage and in 2013 over 150,000 total hip and knee replacements were conducted. Due to increasing ageing and obesity in the UK population, this number is likely to increase each year. Sometimes, problems can develop with the replaced joint over time and a small percentage of people require further surgery. Because joint failure is not always associated with symptoms, follow-up care is provided to ensure that problems are identified as early as possible.
Towards UK post Arthroplasty (the surgical reconstruction or replacement of a joint) Follow-up recommendations (UK-SAFE) is funded by the National Institute for Health Research (NIHR) - Health Services and Delivery Research (HS&DR) with reference 14/70/146
(see https://www.journalslibrary.nihr.ac.uk/programmes/hsdr/1470146).
The project will examine the requirements for arthroplasty follow-up and produce evidence and consensus-based recommendations as to how, when and on whom follow-up should be conducted. The University of Leeds have assembled a highly experienced multi-disciplinary team from the Leeds and Oxford NIHR Musculoskeletal Biomedical Research Units with the necessary academic expertise to tackle the methodological challenges in undertaking this work to ensure the project yields meaningful results that are accepted by key stakeholders.
UK-SAFE is a research project sponsored by the University of Leeds and funded by the National Institute of Health Research (NIHR) Health Services and Delivery Research Programme (see https://www.fundingawards.nihr.ac.uk/award/14/70/146).
UK-SAFE comprises of a number of Work Packages, which are led by co-applicants from different institutions, including the University of Leeds and the University of Oxford.
The specific work package to which this application relates - UK-SAFE WP2a (RO-HES) - is being undertaken at the University of Leeds. University of Leeds is the data controller in respect of the data within this work package. University of Oxford is not a data controller or processor in respect of any data for UK-SAFE WP2a (RO-HES).
Further information regarding the Work Packages can also be found on the UK-SAFE Project Web site (see https://leedsbrc.nihr.ac.uk/uk-safe-project/).
Work Package 2 of the UK-SAFE project focuses on 'determining when, which and how patients present for revision surgery' and is itself divided into two Work Packages:
1. Work Package 2a which focuses on analysis of data from routine datasets. Work Package 2a is further sub-divided into three Work Packages:
i) Work Package 2a (CPRD-HES) - led by the University of Oxford
ii) Work Package 2a (RO-HES) - led by the University of Leeds
iii) Work Package 2 (NJR-HES-PROMS) - led by the University of Oxford
2. Work Package 2b which focuses on analysis of a prospective cohort.
The 3 Work Packages within Work Package 2a have been designed to provide different, complementary views on 'when, which and how patients present for revision surgery' by drawing on different routine datasets. Work Package 2a (CPRD-HES) and Work Package 2a (RO-HES) provide different, complementary views that include consideration of primary care. Inclusion and exclusion criteria for cohorts and data items, and analytical techniques to apply to these data, have been determined by the research teams at the University of Oxford and the University of Leeds to ensure the comparability of results between Work Package 2a (CPRD-HES) and Work Package 2a (RO-HES).
This application (DARS-NIC-147997-R8B9S) relates only to Work Package 2a (RO-HES), which is led by the University of Leeds. University of Oxford is separately responsible for Work Package 2a (CPRD-HES) and the other Work Packages within the UK-SAFE project for which they provide the leadership.
The University of Leeds is the Data Controller for the data referenced in this application, and the data is processed at the locations listed in 'Section 1c - Data Processor(s)' of the application. Analysis of the data supplied from this application will be undertaken by a team of researchers based at the University of Leeds only. Aggregated results from analysis will then be reviewed by the Study Management group.
The UK SAFE project will examine the requirements for arthroplasty follow-up and produce evidence and consensus-based recommendations as to how, when and on whom follow-up should be conducted.
UK SAFE comprises of 3 complementary evidence synthesis work-packages to inform a final consensus process.
Work packages 1-3 will be discrete research projects, conducted independently. However, knowledge and information from each will feed into and inform the other work streams with some tasks being conducted in parallel.
This project aims to investigate whether good after-care is expensive, in terms of time and money on the part of both patient and hospital staff, and whether individual patient-centred follow-up can better identify potential problems in a timely fashion, to the benefit of all concerned.
Membership of the Study Management Group (SMG) comprises all co-investigators of the UKSAFE programme. The SMG provides advice on the conduct, delivery and dissemination across all work packages in the programme. Under the conditions of funding, the Principal Investigator, (University of Leeds) has responsibility from the National Institute of Health Research (NIHR) for the delivery of the UKSAFE programme. Within this programme, University of Leeds has the sole responsibility for the delivery of the particular work package of the UKSAFE programme to which this application relates (WP2a RO-HES). The purpose for, and means by which this work package is to be delivered have been specified and agreed in accordance with the NIHR funding process. Any comments received from the SMG in respect of the work package are advisory.
This agreement is for data that will be used on Work Package 2a (RO-HES) which is being undertaken at the University of Leeds.
Work Package 2a (RO-HES) has the following objective:
- To determine when, which and how patients present for revision surgery
To fulfil this objective, Work Package 2a (RO-HES) will undertake a retrospective cohort study using the following sources of routine NHS data:
1. Hospital Episode Statistics (HES) : a database provided by NHS Digital containing patient data relating to A&E, inpatient and outpatient episodes
2. ResearchOne : a research database containing de-identified patient data from primary care settings that use the SystmOne clinical information system.
For patients with an inpatient admission (Index Episode) to a hospital in England within the defined index period (1st April 2000 31st March 2015) for one of the following procedures:
i) hip replacement
ii) hip revision
iii) knee replacement
iv) knee revision,
The following data will be obtained from Hospital Episode Statistics (HES) for the period from 1st April 2000 to 31st March 2015:
- A&E attendances with
i) a diagnosis of "dislocation/fracture/joint injury/amputation"
ii) a diagnosis (anatomical area) of Hip, Groin, Thigh, Knee or Lower Leg.
- Inpatient admissions with a treatment specialty of:
i) Trauma and Orthopaedics
ii) Rheumatology.
- Outpatient appointments with a treatment specialty of:
i) Trauma and Orthopaedics
ii) Rheumatology.
For patients included within the HES data, the study will determine whether primary care data exists for the patients within TPP's ResearchOne database. If so, a defined set of primary care data will be obtained for these patients for the period prior to 1st April 2015. Additionally, a mapping file will be produced by NHS Digital and supplied to the University of Leeds to enable the HES data for a specific patient to be linked to the corresponding primary care data (if present).
From the linked data, longitudinal records covering primary and secondary care will be constructed for patients.
Based on data provided within the National Joint Registry (NJR) Annual Report, 800,683 primary hip replacements, 89,023 hip revisions, 875,585 primary knee replacements and 54,278 knee revisions were reported (subject to specific inclusion and exclusion criteria) the period from 1 April 2003 to 31 December 2015. Therefore, for a comparable period within the study, it is anticipated that around 900,000 hip replacements and 1,000,000 knee replacements (1,900,000 joint replacements in total) will be identified.
The scope of all hospitals in England has been chosen to enable variation in follow-up for hip and knee replacements and revisions between hospitals to be analysed. The time period of 15 years over which patients will be identified has been chosen to enable variation in follow-up for hip and knee replacements and revisions for patients over time to be analysed.
The legal basis under which data is processed within UK-SAFE Work Package 2a (RO-HES) is:
Article 6 (1) (e) - "processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller;"
The University of Leeds (as it is formally and legally known) is an independent corporation established by Royal Charter. Its objects, powers and framework of governance are set out in the Charter and its supporting statutes, amendments. The University of Leeds received its Charter as an independent institution from Edward VII in 1904. The royal charter under section II states that The University shall have the powers following:
To provide for instruction in such branches of learning as the University may think fit, and also to make provision for research and for the advancement and dissemination of knowledge.
Processing of data concerning health (and other special categories of data) requires the fulfilment of an additional condition under GDPR. The specific condition fulfilled by the processing of such data within UK-SAFE Work Package 2a (RO-HES) is:
Article 9 (2) (j) - "processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law which shall be proportionate to the aim pursued, respect the essence of the right to data protection and provide for suitable and specific measures to safeguard the fundamental rights and the interests of the data subject."
The data are required for research purposes in the public interest - meeting the conditions in the DPA 2018 Schedule 1 Part 1 (4) - which GDPR Recital 52(2) determines is an appropriate derogation from the prohibition on processing special categories of personal data.
Expected Benefits:
Benefits as described in the NIHR funding application.
Upon completion, this research will have major immediate effect on national NHS planning and budgeting and patient well-being. The outputs will be evidence-based support for timing of followup and identification of the most cost-effective follow-up model. This fits directly within the NHS framework for improving outcomes from elective procedures. Rationalising current diversity of followup practices should enable substantial savings for the NHS. Novel follow-up strategies, such as creating a rapid access pathway after joint replacement for symptomatic patients will be examined. The University of Leeds envisage outputs to be readily applicable to the wider NHS, not only hip and knee but also other joint replacements.
The impact will be to reduce the burden on patients and the NHS in terms of outpatient visits and clinical tests that do not add benefit, while optimising detection of potential problems. From an NHS perspective, this work will provide NHS managers with economic and clinical information on arthroplasty follow-up to inform service planning and delivery, and the role of arthroplasty practitioners in this service; provide orthopaedic surgeons with guidance on follow-up, including patient and economic considerations of factors involved; produce arthroplasty follow-up guidelines for adoption by the relevant specialist societies and inclusion with information for their members. From a patient perspective, this work will help to inform patients about follow-up practice and empower them to make choices about future healthcare relating to their joint arthroplasty.
At the end of the project, a policy document will be created with support of the relevant societies, NHS England, CCGs and patient representation. It is anticipated that this will include a stratification algorithm to determine appropriate follow-up for an individual patient, taking into account, for example, implant type and patient factors, and that recommended follow-up pathways for hip may differ to those for knee. This advisory document will be disseminated to all stakeholders, including orthopaedic surgeons, arthroplasty surveillance professionals and NHS managers. With the committed support of these key organisations, it is anticipated that these guidelines will be positively received and that implementation will be widespread. It is the University of Leeds's ambition for the recommended follow-up pathway/s defined by this programme of work to be adopted for all hip and knee replacement patients in the UK and internationally.
Outputs:
This project may deliver the first research-supported, best-for-patient, joint-specific, cost-effective recommendations for follow-up care, providing a gold standard for clinical excellence, and follow-up advice for patients, surgeons, purchasers and health services. Value is not limited to the UK, but has massive global potential.
Nationally, (if successful) the outputs, in the form of an executive summary statement of the agreed pathway/s will be disseminated through appropriate NHS Networks, the NHS England Elective Orthopaedics Subcommittee, the NHS Institute for Innovation and Improvement and professional societies. Dissemination will be key to developing a culture of finding the best way of doing something and doing it everywhere to significantly reduce wastage of clinical resources and optimise NHS spend. The University of Leeds have support of the British Hip Society (BHS), British Orthopaedic Association (BOA), British Association for Surgery of the Knee (BASK), NHS England, Arthroplasty Care Practitioners Association (ACPA), the National Joint Registry and three Leeds-based CCGs for this research and for dissemination activities. This includes individuals from these organisations sitting on the project Independent Advisory Group and attendance of representatives from each organisation at the final dissemination meeting in order to promote further cascading of study results. They will not influence the results in any way - just advise on how is best to cascade accordingly.
Support from these organisations in this context refers to broad agreement with the aims and objectives of the project and an interest in the outputs generated by the project. These organisations have no data controller or processor responsibilities in respect of the data from NHS Digital.
The study may put forward the consensus statement to each societys AGM for adoption as a resolution (if successful).
Internationally, dissemination platforms are already in place through the International Society of Arthroplasty Registers (ISAR) and the European Federation of National Associations of Orthopaedics and Traumatology (EFORT).
Overall and individual work-packages findings may be disseminated through a variety of media. Abstracts may be submitted to major British and international orthopaedic conferences, and separate relevant meetings, including the Health Economics Study Group and Exploiting Existing Data for Health Research conference. The University of Leeds will look to present at the NIHR Methodology Conference and NHS Management conferences and events. Manuscripts will be submitted to appropriate peer-reviewed journals, including general medical, orthopaedic and management journals if appropriate.
Patient dissemination will be supported through the Leeds Biomedical Research Centre Patient and Public Involvement (LBRC PPI) forum and website. Patients with relevant lived experience of the conditions will be involved throughout the programme of work, including one PPI co-applicant and two lay members of the study Independent Advisory Group (both patients with relevant lived experience). The University of Leeds (if appropriate) will hold a PPI conference at the end of the study and will encourage the PPI representatives to be involved in presentations, with support from research staff, to help ensure conference material is appropriate. With lay representatives the University of Leeds will write a lay summary for publication in a patient publication such as The Patient or Inspire (if the project is successful).
To minimise any risk that data published by the research team discloses the identity or attributes of specific patients.
All published outputs from WP2a (RO-HES) will be assessed against the NHS Anonymisation Standard (see http://www.isb.nhs.uk/documents/isb-1523/amd-20-2010/1523202010sp ec.pdf) and ICO's Anonymisation: managing data protection risk - code of practice (see https://ico.org.uk/media/1061/anonymisation-code.pdf) and approved by the Principal Investigator prior to publication.
Any published outputs generated using the data from NHS Digital will contain only aggregated data with small numbers suppressed in line with the HES Analysis Guide
Processing:
A summary of the data flows, which are performed using either: i) NHS Digital's Secure File Transfer (SEFT) or ii) University of Leeds LICTR's Secure File Transfer (SFT), is provided below. This list below explains the TRANSFER MECHANISM - further details of the full flow are included later on in this section.
1. University of Leeds provides TPP (SystmOne) with the cryptographic salt (via SFT)
2. University of Leeds provides NHS Digital with the cryptographic salt (via SFT)
3. NHS Digital provides the University of Leeds with HES A&E, Inpatient and Outpatient data according to specified criteria with patients referenced by HESID (via SEFT)
4. NHS Digital provides TPP (ResearchOne) with a set of patient pseudonyms (via SEFT).
5. TPP (ResearchOne) provides University of Leeds with primary care data for patients identified from the set of patient pseudonyms supplied by NHS Digital with patients referenced by ROID (via SEFT).
6. TPP (ResearchOne) provides NHS Digital with a mapping from each patient pseudonym to a unique ROID (via SEFT)
7. NHS Digital provides University of Leeds with a mapping file that maps a unique HESID to a unique ROID identifier (via SEFT)
The data which will be accessed by the University of Leeds will be pseudonymised. They will have no access to identifiers. They are not permitted to use the data provided to try and re-identify any individual.
Importantly, University of Leeds do not receive any pseudonyms from NHS Digital or ResearchOne.
University of Leeds receives: i) data from NHS Digital where patients are referenced by a HESspecific identifier, ii) data from ResearchOne where patients are referenced by a RO-specific identifier, and iii) a file from NHS Digital which maps HES-specific identifiers to RO-specific identifiers. Linkage of the HES-specific identifier to RO-specific identifier is undertaken at NHS Digital.
ResearchOne has been separated out in the summary above to TPP (ResearchOne) and TPP (SystmOne). Project documentation (Protocol) refers only to ResearchOne to emphasise that the project will use only data from the ResearchOne database. The Phoenix Partnership (TPP) are responsible for SystmOne, ResearchOne, and for ensuring the necessary separation of duties for staff working on SystmOne and ResearchOne.
NHS Digital and TPP will transfer the set of patient pseudonyms (via SEFT) in line with the correct procedures . The ResearchOne database is stored and processed inside the data centres which host the SystmOne production environment. The databases are in Tier 3 data centres that have been accredited by the NHS for storing and processing clinical data. There is a disaster recovery site (hosted to exactly the same standards as the live site) which is used as a back-up location in the event of any failures at the main site. Documentation relating to ResearchOne can be found at:
http://www.researchone.org/documentation/.
University of Leeds generates and supplies a salt key that is used in the generation of pseudonyms by NHSD and TPP (SystemOne). To ensure that the identifier used to generate the pseudonyms (NHS number) cannot be recovered by the University of Leeds, the University of Leeds does not receive any pseudonyms generated using the supplied salt key.
The salt key is a random string. The salt key is generated for this specific project by the University of Leeds and securely transferred to NHS Digital and TPP. The key is then used by NHS Digital and TPP in conjunction with NHS number to generate pseudonyms for patients. These pseudonyms are used by TPP to determine whether patients are present in ResearchOne and by NHS Digital to generate a mapping file that is provided to the University of Leeds.
The salt file represents a random string of defined length that is used as an additional input to the pseudonym generation process to reduce the risk
that: i) NHS numbers could be recovered from pseudonyms, and ii) pseudonyms generated from NHS numbers for different projects (and any associated data) could be matched. Use of the salt key in the pseudonym generation process provides a safeguard against the potential recovery of the NHS number from a pseudonym by a brute-force attack where pseudonyms are generated for all possible NHS numbers as such an attack would also require to the attacker to have access to the salt key.
Data extracts from ResearchOne contain unique references for each patient that are project-specific i.e. the reference for a given patient will be different in any two data extracts from ResearchOne. The terms ROID or ResearchOne ID are used for these references within the project documentation.
o For a given data extract, these project-specific unique references are created and assigned as part of the extract generation process.
o To facilitate linkage with data from NHS Digital for this project, TPP will also generate a pseudonym for each patient as part of the extract generation process, using the salt supplied by UoL and the NHS number contained in the SystmOne data (from which ResearchOne data is generated). (Point 1 + 2 + 3 above)
o NHS Digital will supply a list of pseudonyms to TPP which will represent those patients to include in the data extract from ResearchOne. (Point 4 above)
o TPP will determine those patients for whom data exists within ResearchOne by matching pseudonyms in this list with those created as part of the extract generation process.
o TPP will then supply NHS Digital with a file that maps pseudonyms to ROIDs for the subset of patients who are present in ResearchOne. (point 6)
o NHS Digital will use the file supplied by TPP to generate a file that maps HESIDs to corresponding ROIDs. The file generated by NHS Digital will be supplied to UoL to enable data relating to a given patient to be determined in both the HES and ResearchOne data. (Point 7 above)
o TPP will also supply UoL with a data extract containing the required data items where each patient is uniquely referenced by a ROID. TPP does not supply the pseudonyms to UoL. (Point 5)
The University of Leeds receives the following:
i) HES data referenced by a HES ID
ii) ResearchOne data referenced by a RO ID
iii) a mapping file from HES ID to RO ID.
The linkage methodology has been developed so that the University of Leeds is responsible for the generation and supply of the salt key, and subsequent data flows to the University of Leeds do not contain any data that could be re-identified by the knowledge of the salt key. Additionally, the salt key is used only a one-time basis, such that any pseudonyms generated cannot be matched across data sets obtained for different usages. Approvals for the project (including NHS Ethics) have been obtained on the basis of the proposed linkage methodology.
NHS Digital will identify patients based on the presence of an inpatient admission (Index Episode) to a hospital in England within the defined index period (1st April 2000 31st March 2015) for one of the following procedures: i) hip replacement, ii) hip revision, iii) knee replacement, or iv) knee revision. For these patients, NHS Digital will identify any of the following in the period for 1st April 2000 31st March 2015:
- A&E attendances with i) a diagnosis of "dislocation/fracture/joint injury/amputation" or ii) a diagnosis (anatomical area) of Hip, Groin, Thigh, Knee or Lower Leg.
- Inpatient admissions with a treatment specialty of i) Trauma and Orthopaedics or ii) Rheumatology.
- Outpatient appointments with a treatment specialty of i) Trauma and Orthopaedics or ii) Rheumatology.
This data will be provided directly to the University of Leeds with patients uniquely referenced by a unique HESID. Additionally, NHS Digital will generate a pseudonym for each included patient, according to the methodology described above, and supply this list of pseudonyms to TPP (ResearchOne).
TPP will generate pseudonyms for all patients in the ResearchOne database by applying the same methodology as NHS Digital and using the salt key supplied to TPP (SystmOne). TPP (ResearchOne) will then determine those patients whose pseudonyms are present in the list provided by NHS Digital. Selected primary care data will be extracted from ResearchOne for these patients for the period prior to and including 31st March 2015.
Primary care data will only be obtained where:
- the GP practice to which the patient is registered using TPP's SystmOne clinical information system and
- has opted-in to ResearchOne (and the patient has not individually opted-out).
TPP (ResearchOne) will provide primary care data directly to University of Leeds. Each patient will be uniquely referenceable in this data using a unique ROID. No pseudonyms will be included in the data provided by ResearchOne to the University of Leeds. TPP (ResearchOne) will also provide NHS Digital with a file that maps each pseudonym present in the list provided by NHS Digital and in the ResearchOne database to its corresponding ROID.
NHS Digital will use the mapping file provided by TPP (ResearchOne) to map the HESID of each patient in the HES data to the ROID identifier of each patient in the ResearchOne data. NHS Digital will supply the resulting mapping file to the University of Leeds who will use it to match the data for a particular patient in HES data to the data for that patient in the RO data (and vice-versa).
Survival analysis will be used to model time to revision. To determine the follow up time of revision, a smoothed Nelson-Aalen cumulative hard rate will be examined to identify any peak in the mid-long term risk of revision. Survival analysis is a statistical technique used to analyse the time until a particular event happens. In this case, the particular event would be a hip/knee revision.
To identify patients most likely to require revision, proportional hazards regression will be used to identify pre-, peri- and post- operative predictors of mid-late term revision.
The project seeks to determine those factors that predict mid-late term revision. The factors are categorised by the time at which their value is determined relative to the operation: pre (before) peri (during) and post (after). Cox proportional hazards regression modelling is a statistical technique used to determine associations between the time of an event happening (e.g. revision) and these factors.
The date of the first incidence of a subject's hip or knee replacement will be used as the start time. The event of interest in all time-to-event models will be the first recorded revision operation. Cox proportional hazards regression modelling will be used to identify pre-, peri- and post- operative predictors of midlate term revision (defined as more than 5y post primary surgery). Should testing reveal that the proportional hazards assumption is not valid, then parametric modelling will be used instead. Shared frailty will be modelled with a random effect for hospitals/providers and another for general practice, since it is anticipated that both hospital practice regarding follow-up and GP behaviour regarding referral will influence the survival time of the primary joint replacement. Competing risks, including mortality and comorbidities following primary surgery will be considered. Linearity of continuous predictors will be assessed using fractional polynomial regression modelling or splines. Analysis will assess the extent to which the relationship between the value of continuous predictors (i.e. predictors whose values might be, for instance, decimal numbers) and time can be represented by a linear function (straight line).
Missing data will be handled by using multiple imputation methods using the ICE (Imputation by Chained Equations) procedure.
Inclusion and exclusion criteria for patients and data items were determined by members of the project team who provided clinical, technical and statistical input. Only those patients and data items determined to be necessary and sufficient to answer the research question were included.
UK-SAFE WP2a (RO-HES) is not part of a PhD project.

Objectives:
The COVID-19 pandemic is a major global challenge, whose impacts on the population’s health, healthcare systems and services and the wider economy will be apparent for many years.
During the first wave of the pandemic dramatic reductions were detected in the demand for, and supply of, cancer services which did not fully recover prior to the arrival of the COVID-19 second wave. These may contribute, over a 1-year time horizon, to substantial excess mortality among people with cancer and multimorbidity. It is a matter of great urgency to understand how the recovery of general practitioner, oncology and other hospital services might best mitigate these long-term excess mortality risks
The indirect impacts on the presentation, diagnosis, management and prognosis of cancer resulting from the response by governments and health services to the COVID-19 pandemic also need to be examined. A deeper understanding of the nature and extent of these unintended consequences, including the range of conditions affected, variation by patient characteristics (such as age, sex, ethnicity, and deprivation) and geography (both within and between regions), effects on different in- and out-patient services and treatments, and changes over time in response to mitigating actions (e.g. regional and national government advice), is urgently needed to inform government and NHS policy.
Under this Agreement, employees of the University of Leeds and Leeds Teaching Hospitals NHS Foundation Trust (LTHT) will use the Cancer Trusted Research Environment (TRE) service for England to enable analyses of linked, nationally collated healthcare datasets to enumerate the impact of COVID-19 on cancer pathways. The research questions will delineate the precise impact of the COVID-19 pandemic on cancer systems and cancer patients. This requires access to both historical data (pre-2020) and near real-time data on patients referred with (i) a suspicion of cancer and (ii) those diagnosed with and/or managed for cancer.
The specific aims are to examine the effects of COVID-19 on:
• Cancer referral (including those which lead to a cancer diagnosis and those where cancer is excluded);
• Cancer diagnosis (including date, tumour site, stage, grade, morphology and key molecular/genetic/ phenotype);
• Cancer treatment (including surgical procedures, chemotherapy/targeted therapy and radiotherapy);
• Clinical trial activity including recruitment to and active treatment within trials;
• Outcomes (including both hospital admission, survival, mortality and cause of death) and;
• COVID status (including COVID testing (Pillar 1&2) and results, acute hospitalisation and related direct COVID deaths in cancer patients).
• Rates of COVID infection, hospitalisation and death in discrete health care regions
This programme requires access to both historical data (pre 2020) and near real-time data on patients referred with (i) a suspicion of cancer and (ii) those diagnosed with and/or managed for cancer. A comparison of activity from 2019 and 2020 will be undertaken but this will include patients diagnosed with cancer at any time before then. A maximum of 10 years data prior to 2020 would be required to enable cancer survival analyses at 1, 2, 5 and 10 year intervals. These are the standard research mortality statistics.
The work would be organised into work packages (WPs) to be led by representatives of DATA-CAN employed by either the University of Leeds or LTHT. Each work package is considered by the members of DATA-CAN’s Management group for scientific and clinical ratification. The Management group includes a Patient and Public Involvement and Engagement (PPIE) Lead. This group will give independent advice to the work package lead. Once finalised, the work package will be assigned to an approved individual with relevant expertise to undertake the work in the Cancer TRE.
PPIE involvement will be embedded throughout all activities, as this is a core way of working for DATA-CAN.
For instance, across DATA-CAN have had PPIE representation in the selection and interview panels for the Chief Operating Officer, in every proposal or approach received from commercial organisations, in the development and uses of real-time data (for instance in the Covid-19 and cancer work), at all management groups and at all Steering Groups. DATA-CAN’s PPIE members have also undertaken in-depth work looking at the “value” of several large-scale organisations. To ensure PPIE members are supported and play a full and active part in all DATA-CAN activities, they are provided with in-depth training on “patient data” including 1:1 mentorship, 2-weekly data-drop-in sessions, a set of bespoke learning resources, plus direct access to the PPIE Lead for advice at any time.
In respect of DATA-CAN’s used of NHS Digital’s Cancer TRE, some specific areas where patients will be represented by the PPIE group is in:
• The operational processes of running the TRE, including safeguards, controls audits and transparency.
• Reviewing any application to utilise the data in the TRE, including making sure that the application is clearly understandable and has clear potential for patient benefit.
• Reviewing or producing lay summaries of the activity of the TRE, including website content and external communications.
• Mapping out the optimal routes for dissemination for patient benefit, rather than just relying on publication in academic journals. This will include an up-front communications plan for different pieces of work, co-designed with the PPIE group, ensuring results are disseminated and promoted to a lay audience, encouraging them to use this information further.
• PPIE members have a real interest in impact, rather than just the “doing” of the research. They are mapping the “reach” of current PPIE group members, recognising many of them will also be involved with other local and national work, or with charities. DATA-CAN’s philosophy is to utilise those links/voices to ensure results are communicated out widely, ensuring a greater awareness and understanding of the work of the TRE.
• Working with the DATA-CAN Communications team, ensure the best use of social media to advertise the work of the TRE, the outcomes of any results, and the implications for the NHS and patients (current and future).
• Contributing to the production of a lay-accessible annual patient report, which will describe the work of the overall programme, including the activity and outputs of the TRE, with details of the benefits of the work which has been produced.
• Supporting the work of the use MY data patient movement, which operates independently from DATA-CAN. Their communication routes can be seen, through their Newsletter and other means, as another mechanism to communicate with a wider group.
• Lastly, the PPIE group will play a leading role in communications through media and third sector organisations by co-authoring lay summaries or case studies, by providing patient quotations in press releases, and potentially by engaging directly with the media.
The following work packages (WP) have been identified and ratified by the process described above:
WP 1 – Coordination (led by DATA-CAN):
This work package aims to identify relevant datasets and required dataset linkages across the UK; to coordinate applications for relevant research group access for work packages if not being conducted by DATA-CAN partners, and to coordinate specialist inputs from the oncology community and other relevant clinical groups. Work is ongoing across all four nations to identify and assemble the relevant national datasets, enable their linkage, agree mechanisms for regular updates and establish routes for expedited approval and access for approved researchers within trusted research environments in each of the four nations.
WP 2 - Analyses:
This work package aims to refine questions with appropriate clinical specialist input, draw up analysis plans for different datasets (individually and linked), assess data completeness and quality, conduct analyses, interpret results, iterative reporting and refining of analyses. Analyses based on routinely collected, national healthcare datasets have the advantages of large scale and comprehensive coverage, maximising statistical power as well as inclusiveness/representativeness (e.g. across all age groups, ethnicities, geographies and socioeconomic settings).
WP 3 - Public, patient and professional involvement and communications:
Work DATA-CAN Patient, Public, Involvement and Engagement group and other PPIE panels/ professionals to provide input into refining questions, assessing the impact of the results, and preparing reports for lay audiences. Lead on communications of activity and emerging results through websites, social media and other outlets. Lead on interactions with press and other media.
These work packages relate to the use of data in the TRE in the following ways:
- WP1 has led to the identification of and aspiration to access the datasets via the TRE under this Agreement for the purposes described under WP 2.
- WP2 has yielded a number of planned analyses to be undertaken within the TRE. Those that have been planned via this process so far are described below as indicative examples to give insight into the work that will be undertaken under this Agreement. However, during the course of this Agreement, WP2 will yield additional analysis plans as new questions emerge and will go through the same ratification process prior to being assigned and undertaken.
- WP3 will focus on the outputs of WP2 including the outputs of analyses undertaken using the data in the TRE.
The following are examples of analysis plans which will be undertaken using the data in the TRE under WP2:
• WP 2.1 - Indirect impact of COVID-19 on cancer:
An analysis of time trends in hospital activity (admissions by diagnosis, treatments, procedures) using hospital and disease audit datasets, registered deaths by cause and primary care activity before, during and after COVID-19 pandemic. An immediate priority for informing government policy across the UK is to assess the indirect impact of COVID-19 on cancer. Analysis will address trends in cancer referral and diagnosis before and during the COVID-19 pandemic in England and will be extended to incorporate data from the other UK nations (Scotland, Wales and Northern Ireland) when it becomes available.
• WP 2.2 - Influence/associations of cancer on COVID-19 outcomes (such as admissions to hospital, admission to ITU, mechanical ventilation and death):
The influence/associations of pre-existing cancer diagnosis on COVID-19 incidence and outcomes will be studied through linkage of large scale population wide datasets that contain information on previous medical history with COVID-19 test results, hospitalisation, critical care and mortality datasets, with adjustment for multiple confounders (including risk factors and co-morbidities).
• WP 2.3 - Influence/associations of cancer risk factors on COVID-19 outcomes:
The influence/associations of cancer risk factors on COVID-19 incidence and outcomes will be studied through linkage of large scale population wide datasets that contain information on cancer risk factors such as blood pressure, body mass index and smoking status with COVID-19 tests, hospitalisation, critical care and mortality datasets, with adjustment for multiple co-morbidities.
• WP 2.4 - Influence/associations of cancer medications on COVID-19 outcomes:
This package will provide information to enable government agencies (e.g., MHRA and NICE) to give evidence-based advice to healthcare professionals and patients on drug regimens and risk of COVID-19. Impact of the NICE COVID interim treatment regimens on COVID-19 outcomes (hospitalisation, admission to ICU, mechanical ventilation and mortality).
• WP 2.5 - Direct impact of COVID-19 disease on cancer disease occurrence, re-occurrence and outcomes in short, medium and long term:
Linkage of population routine datasets (demography including mortality, primary care, hospital) and audit datasets will enable comprehensive assessment of the impact of COVID-19 disease on cancer occurrence, reoccurrence and outcomes in short, medium and long term. With SARS-CoV2 potentially circulating for at least several years in the population, it will be important to estimate the short-, medium- and long-term effects of infection on incidence of cancer.
Governance Considerations:
The University of Leeds and the Leeds Teaching Hospitals NHS Trust are joint Data Controllers.
The University of Leeds and the Leeds Teaching Hospitals NHS Trust are founding members of DATA-CAN along with:
• UCLPartners
• Queen’s University, Belfast
• Genomics England
• IQVIA
DATA-CAN funding pays for staffing posts with founding member organisations. Acting as agents of their substantive employers, postholders have freedom to identify, plan, refine and assign work packages in support of DATA-CAN’s aims such as those to be undertaken in the Cancer TRE. All decisions concerning the purpose for and manner of processing personal data as described in this Agreement have been taken by employees of the University of Leeds and of the Leeds Teaching Hospitals NHS Trust.
Only the University of Leeds and Leeds Teaching Hospitals NHS Trust, who are the data controllers, and substantive employees of these organisations will have access to the record level data within the TRE. No other collaborators have involvement either in capacity as a data controller or processor.
While UCLPartners are the legal vehicle for the DATA-CAN hub, they do not have the work force for, or track record of, data analysis or data management. In accordance with the DATA-CAN consortium agreement the main data analyst resource is concentrated in Leeds and Belfast partner organisations. Under this Agreement, the Belfast partner organisation, Queens University, Belfast, has no involvement either in capacity as a data controller or processor.
The legal basis for the data controllers to process personal data is GDPR Article 6(1)(e) ‘task in the public interest’ and for processing special categories of personal data the legal basis is GDPR Article 9(2)(j) ‘archiving, research and statistics (with a basis in law)’.
Data Requirements:
These analyses require access to linked data from the personal demographic service, primary care, hospital emergency, inpatient and outpatient care, intensive care, registered deaths by cause, cancer registries and COVID-19 laboratory testing. All data will be accessed by named, approved researchers (certified to have successfully completed safe researcher training) in the Cancer TRE within NHS Digital.
The data within the TRE will be pseudonymised. NHS Digital will strip identifiers from each record, apply a pseudo-ID to each record and perform the data linkage. No identifiable data will be accessible within the TRE.
The following linked datasets will be required for the purposes of this programme of work:
1. COVID-19 Second Generation Surveillance System (Beta version)
2. COVID-19 UK Non-hospital Antigen Testing Results (pillar 2) Service Types
3. CHESS: COVID-19 Hospitalisation in England Surveillance System
These datasets will provide details of COVID-19 test results and acute hospitalisations from COVID-19. These datasets will be used to ascertain all cases with proven SARS-CoV2 infection and to provide information on the severity and treatments of people with COVID-19.
Linkage of these data to data on hospitalisations, intensive care and mortality will be used to indicate the severity of COVID-19 disease. Data across all datasets should include information on patients who died prior to 2020 to all comparison of medical histories and mortality associated with a range of conditions prior to, during and – in due course – after the COVID-19 pandemic.
4. National Cancer Registration Dataset
5. Rapid Cancer Registration dataset
6. Systemic Anti-Cancer Therapy (SACT)
7. Radiotherapy Dataset (RTDS)
8. National Cancer Waiting Times (NCWT)
These datasets will provide details of urgent cancer referrals including cancer waiting lists; details of surgeries and treatments including radiotherapy and chemotherapy including treatments within a clinical trial.
9. Civil Registration Mortality data
This dataset will provide survival data. Mortality data are needed to provide information on dates and underlying and contributing causes of death as part of the assessment of the severity of the COVID-19 disease and its impact on cancer.
10. Secondary Uses Service (including SUS PBR for HRGs cost analysis)
11. Hospital Episode Statistics (HES) Admitted Patient Care
12. HES Outpatient
13. HES Accident & Emergency
14. Emergency Care Data Set (ECDS)
15. GPES Data for Pandemic Planning and Research (GDPPR)
16. Medicines dispensed in Primary Care (NHS BSA data)
These datasets will provide details of patients’ prior medical history (co-morbidities); details of hospital attendances for cancer conditions before, during and (in due course) after the COVID-19 emergency, and information needed to assess other risk factors (age, sex, ethnicity, socioeconomic status, obesity, high blood pressure, high cholesterol, diabetes, etc.) and prescribed medications for those who have and have not gone on to develop COVID-19 disease with varying levels of severity.
The above data will be minimised to:
- only include those datasets required to address the cancer-related questions included within the Agreement;
- only for cancer-related research purposes, as outlined in the proposal;
- have a “per project” basis (by dataset, by year, and by “groups” of fields rather than individual fields)
- only be included if they are urgent or do not require data minimisation beyond minimisation at the dataset level (as an interim measure until these data minimisation techniques can be applied).
Some analyses based on primary care data will require analysis at the level of individual GP practices. For example, this will be required for work package 2.5, which aims to use practice prescribing preferences as an instrumental variable to assess the potential effects of different antihypertensive medications on outcomes of COVID-19. However, by default, no individual practice or health service practitioner will be identified in any research output. Should any research project be proposed that would require the identification of individual practices, researchers would seek guidance from NHS Digital and their GP advisory group about any issues that this might raise (for example, the potential identification of practitioners in single-handed practices) and how these should be addressed.
Expected Benefits:
Through addressing questions about the impacts of cancer on COVID-19 and the impacts (both direct and indirect) of COVID-19 on cancer, DATA-CAN expects the outputs of this work to inform public health policy and clinical care, benefiting:
• patients with a history of cancer who are at increased risk of poor outcomes with COVID-19 as a result of their cancer or cancer medications;
• patients now and in the future who become unwell with COVID-19 and are at risk of short, medium and long term cancer complications;
• the population as a whole whose cancer services are being affected by the government and health service response to the COVID-19 epidemic.
As outlined above, outputs which will deliver the capability to provide these benefits are expected to start to emerge within weeks of data becoming available to the research team and will continue to be produced throughout the three year period of the project through to January 2024.
Outputs:
The outputs of each piece of work will be reported to the Scientific Advisory Group for Emergencies (SAGE) and equivalent bodies in the devolved nations so helping to drive evidence-based policy decisions for health service providers and clinical professional groups. Outputs will also form the basis of manuscripts for publication in peer-reviewed scientific and medical journals, presentations at national and international scientific and medical professional conferences, and reports aimed at lay audiences, available through websites, in particular those of Health Data Research UK. Outputs will inform the clinical management of patients with different types of cancer presenting with COVID-19 disease.
All analysis plans, protocols and reports arising from this proposal will be made publicly available via the HDR UK website (linking to additional institutional documentation if appropriate), HDR UK github repository and open access publications. Hence all outputs will be freely available.
All reports for government advisory groups and policy makers, the lay public and academic publications will be written in the name of DATA-CAN with all relevant individual contributions (coordination, writing, analysis, interpretation etc.) listed.
Outputs will contain only aggregate data with small numbers suppressed in line with the HES analysis guidance from NHS Digital, Public Health Scotland and the SAIL Databank for Wales.
No individual practice or health service practitioner will be identified in any research output.
It is expected that outputs will start to emerge within weeks of data becoming available to the research team and will continue to be produced throughout the three-year period of the project through to January 2024. By their nature, those outputs providing information on the longer term impacts and implications of these for clinical care and public health policy will take at least several months to start emerging.
Processing:
Individually authorised analysts employed by either the University of Leeds or LTHT will be granted remote secure access to the Cancer Trusted Research Environment (TRE) within NHS Digital’s data platform, the Data Processing Service (DPS).
Within the Cancer TRE, the analysts will be able to access pseudonymised linked data from the datasets outlined above.
No details which directly identify data subjects, such as names, NHS Numbers, etc., will be accessible within the TRE.
Analysts will be authorised to access only the data they are permitted to see and can utilise a variety of analytical tools available within the TRE platform.
Only summary, aggregate results data (data will be aggregated with small numbers suppressed in line with the HES analysis guide) will be exported from the TRE and this will be subject to review and approval by the NHS Digital team providing the TRE. The objective of this will be to ensure that no output contains information which could be used either on its own or in conjunction with other data to breach an individual's privacy.

Objectives:
The University of Leeds requires HES and mental health data for a specific cohort to be used, alongside data collected in the Yorkshire Specialist Register of Cancer in Children and Young People (YSRCCYP), to continue its epidemiology and health services research programme.
For background, the YSRCCYP is a regional population based register containing detailed demographic and clinical information on children and young adults aged 0-29 years diagnosed with cancer since 1974. The YSRCCYP covers the Yorkshire and Humber Strategic Health Authority (SHA) which has a total population of 5 million people. Spanning an area of 15,000 square kilometres the Yorkshire and Humber SHA comprises a range of urban and rural communities with a significant ethnic minority population resident in parts of West Yorkshire.
The YSRCCYP research team, within the University of Leeds, is notified of patients eligible for inclusion in the YSRCCYP either directly by the patient’s treatment centre or via electronic reports from the National Cancer Registration and Analysis Service. The YSRCCYP research team then obtains information on patients by manual data abstractions from hospital records. Detailed data on the patient and diagnosis, including treatment information for each of these cases is obtained by a sole data collection officer via the medical records at relevant hospitals in the area, and annual follow up of all cases takes place to ascertain data on any relapses or deaths through letters sent either to the patient’s treating consultant or general practitioner. Data on 9,500 patients have been collected since 1974, however linked HES and mental health data was required for only 8,500 as the cohort shared with NHS Digital excludes participants who passed away before 1996. The cohort submission under approval of this request will consist of approximately 7,000 patients.
The YSRCCYP was originally set up in collaboration with local clinicians to provide research information. Since 1994, the YSRCCYP database and research programme has been managed by and at the University of Leeds’ Division of Epidemiology & Biostatistics. The University of Leeds is the Data Controller for the YSRCCYP with sole responsibility for determining the purposes for which and the manner in which any personal data are processed. The work is currently funded by the Candlelighters Trust.
The purpose of the YSRCCYP is to facilitate population-based epidemiological and health services research. The use of HES and mental health data contributes to this by providing additional information that can be linked with and analysed with data from the YSRCCYP data. The HES and mental health data are not added into the YSRCCYP research database. The two datasets are stored separately but contain common unique study IDs enabling data to be linked at record level. Where required for specific research, relevant data are extracted from the respective databases, linked and analysed by the YSRCCYP research team.
A current research focus is on hospital burden around the time of diagnosis and treatment and monitoring long term risks of hospitalisation associated with cancer treatment. One specific processing activity will relate to describing the risks and prevalence of mental health illness within the cancer cohort compared to the general population.
This type of epidemiological and health services research has the potential to benefit future patients by identifying risk factors which can be used by health professionals to identify those at greatest risk of mental health illness so that interventions and appropriate support can be implemented. It may also reveal important environmental risk factors, examine changes in incidence rates which may help to identify possible causes and understand survival patterns according to ethnic group and socio-economic status in order to ensure that there are no inequalities in outcomes or access to specialist cancer care for certain sub-populations.
The YSRCCYP research team’s research plans include the following objectives:
1) To describe the total burden of hospitalisation among the Yorkshire cancer population aged 0-29 years, to identify clinical and sociodemographic factors which influence the likelihood of hospitalisation and to investigate how hospitalisation rates have changed since 1997.
2) To understand patient care pathways through the NHS before, during and after cancer diagnosis. This includes assessment of time to diagnosis for children and young adults diagnosed with cancer under the age of 30 years to identify where improvements can be made to minimise delays in diagnosis leading to better prognosis and less stress and anxiety on patients and their families.
3) To calculate the risks and costs to the NHS of adverse health events requiring hospital admission for survivors of cancer in this age group so that clinicians can provide appropriate follow-up care.
To address aim 1 above the YSRCCYP research team will utilise linked HES and mental health data to investigate long term risks of respiratory and mental health illness in the cohort and identify sociodemographic and clinical factors which may affect these risks. The linked HES and mental health data are covered under a separate Data Sharing Agreement (reference: NIC-11809-H1Y3W).The YSRCCYP research team also wish to determine the relative excess risk of these conditions within the cancer cohort compared to the general background population and, in order to make this comparison, requires a separate pseudo-anonymised extract of HES data containing all episodes for patients in the Yorkshire and Humber SHA area only under the age of 60 at admission (the oldest person currently registered). This separate extract is covered under this Data Sharing Agreement.
The YSRCCYP research team require some data items classed as sensitive. These are the Referrer code, which indicates the manner in which the patient was referred to hospital by ascertaining the code of the referring organisation. This allows the YSRCCYP research team to identify particular patient pathways which are associated with an optimal time to diagnosis, a key indicator known to influence survival. Additionally the Consultant code data field is required because it enables the YSRCYYP research team to work out whether patients receive care at specialist cancer centres as opposed to general district hospitals, in order to address important health services research questions such as: ‘Does specialist care improve patient outcomes for children and young people including length of hospital stay and reduce subsequent morbidity and mortality?’. There are currently no databases which link consultant codes to specialist cancer centres for childhood and young adult cancer, so this process needs to be done manually using cohort linked NHS Digital data and the YSRCCYP database.
Yielded Benefits:
Several peer-reviewed scientific papers incorporating HES and registry linked data have been published including: van Laar M, Feltbower RG, Gale CP, Bowen DT, Oliver SE, Glaser A.

BMJ Open 2017, 7 (9) e016332; DOI: 10.1136/bmjopen-2017-016332 Presentations of on-going work have been presented to academic and clinical audiences including: analysis of mental health late effects to the Royal College of Paediatrics and Child Health 2018 Conference; analysis of respiratory late effects has been presented at the Public Health England Cancer Services, Data and Outcomes Conference in June 2018.
Expected Benefits:
The benefits to health and social care will include:
1. Improved patient care. This work will identify to clinicians, commissioners and patients themselves of those individuals who are at greatest risk of hospitalization; this will enable follow-up practices to be tailored to patient needs, help identify potential health problems early and intervene so that patient wellbeing is maximized and NHS burden minimized. For example, those individuals identified from the risk stratification model as being at greatest risk of mental health illness will be offered additional support from NHS services (e.g. psychiatry, social care) through their treating oncologist or GP. The risks of depression following cancer treatment will help to describe the NHS burden of mental health problems in this vulnerable population. This knowledge will be informative to paediatric oncologists and other allied health professionals caring for patients, as well as their GPs, by improving awareness of the timing when depression is likely to be diagnosed so that the quality of care can be improved. Patients will be informed of their risk group via their treating consultant or at their annual hospital clinic follow up appointment. Their GPs will also be informed of the results of the risk stratification via the hospital consultant team. Anticipated dates to complete these activities are by December 2018.
2. Evaluation of treatments to identify best practice and guidance. Work to understand the reasons for the hospitalisation so researchers can identify whether certain treatments are associated with an increased risk of hospitalisation and disseminate this information through scientific journal articles. This will mean that alternative treatment modalities and optimal care can be planned which minimize these complications. Anticipated dates to complete these activities are by June 2019.
3. Evaluation of service provision. Highlight any inequalities in access to specialist cancer care services, particularly in older teenagers and young adults, so that all patients have an equal chance of obtaining the best care irrespective of their personal circumstances and thereby having the best chance of cure. The work will be written up in the form of reports to commissioners and journal articles so that clinicians and commissioners can use this information in order to make any necessary changes to service delivery so that the entire Yorkshire and Humber cancer population is served equally well. Anticipated dates to complete these activities are by December 2018.
4. Financial planning. Information on hospital activity burden and NHS costs associated with the diagnosis and treatment of children and young adults with cancer will be calculated by the University research team in collaboration with health economists at the Leeds Institute of Health Sciences. Changes in costs over the last 20 years will be reported, adjusting for inflation, in order to provide cost projections over the next 10 years. This information will be collated in the form of a report to specialist commissioners of childhood and adolescent cancer services in the Yorkshire & Humber region so that, where required, service changes can be implemented in order to meet future NHS patient demand. Anticipated dates to complete these activities are by December 2019.
At the moment, these data are lacking and once identified by the YSRCCYP research team, they will provide important information:
* to clinicians to help better manage their clinic populations,
* to specialist commissioners to monitor the effectiveness of cancer care and
* to patients in order to understand more about their own risks of complications associated with the treatment they have received and wherever possible self-manage their own care and wellbeing.
* to identify gaps in access to specialist care by the research team for two distinct populations:
i) teenagers and young adults, who do not benefit from the same level of centralised care as that in place for younger children, and
ii) South Asians as they are more likely to present with cancer due to genetic risk factors. Improving care for teenagers and young adults and the south Asian population will ensure that their survival rates are optimal and equivalent to other age groups and ethnic groups, and any subsequent complications of treatment are minimized and if these do occur are then managed appropriately by specialist NHS professionals to ensure a full recovery.
Outputs, such as the risk stratification model, will be integrated into clinical practice through established links between the YSRCCYP research team and paediatric and adolescent oncologists throughout the Yorkshire region. The research programme as a whole benefits enormously from the long-running, close collaboration with haematologists and oncologists in the Yorkshire and the Humber region who all help to ensure that the University's research findings are effectively translated into clinical practice and are involved in all outputs from the YSRCCYP database.
Outputs:
Work describing risks of health effects of treatment in relation to respiratory illnesses will be completed by the YSRCCYP research team and submitted for publication in the British Journal of Cancer (or similar) by June 2018. The June 2018 publication follows a June 2016 publication where descriptive statistics have been produced showing the respiratory conditions diagnosed within the linked cohort. The background admission rates in the general population are required over the same time period to enable further statistical analysis to be carried out. Outcomes of the work will also be disseminated in open-access journals (e.g. BMC Cancer) and presented at conferences including the National Cancer Registration and Analysis Service Cancer Outcomes annual meeting, Teenage Cancer Trust and the International Society of Paediatric Oncology annual conferences. Further work will be submitted to the European Journal of Cancer (or similar) in relation to specific mental health outcomes by December 2018. Analyses describing the variation in clinical pathways including delays and time to diagnosis will be submitted for publication by June 2018 to Journal of Clinical Oncology (or similar).
Additional work describing the rates of hospital activity and differences between ages at diagnosis (e.g. 0-14 vs 15-29) and ethnic group (e.g. south Asian vs non-south Asian) will be completed by October 2017 and submitted for publication to the British Journal of Cancer by December 2017. Details of risk stratification models and the methodology to derive these for individual patients will be disseminated by the research team to every clinician involved in the care of children and young people (CYP) in December 2018. This will be supported by the Yorkshire & Humber CYP cancer network that holds details of all practicing NHS CYP cancer teams and clinicians in the region.
Summary reports of the work and research undertaken will be compiled and also made available on the Yorkshire Register University of Leeds website (http://medhealth.leeds.ac.uk/info/545/yorkshire_specialist_cancer_register), according to the timelines listed earlier in the document.
All outputs will be aggregated with small number suppression in line with the HES Analysis Guide.
As the funder, the Candlelighters Trust may request information for use in its own information dissemination and publicity materials. For example, they may ask for the number of new cases diagnosed per year in Yorkshire and projected incidence rates. The University of Leeds would only share information that is available as a result of the processing activities described above – i.e. the YSRCCYP would not undertake further data processing in order to derive information requested by the Candlelighters Trust and any information shared would be put in the public domain. For clarity, the University of Leeds is not obliged to provide information on request to the Candlelighters Trust and would not share any data that are not aggregated with small numbers suppressed in line with the HES Analysis Guide.
The linked NHS Digital data alongside the background hospitalisation rates will be used to derive key information which will be provided by the YSRCCYP research team to clinicians involved in the long-term care of young people identifying each individual’s risk stratification group (defined as being at ‘low’, ‘medium’, or ‘high’ risk of future complications or health effects, based upon their previous hospital activity patterns, treatment mortality, dose, cancer type and stage). The risk stratification model will be devised by the YSRCCYP research team and disseminated to clinicians in the Yorkshire and Humber region via the Y&H Children’s and Young People’s Cancer Network (December 2018). Only those clinicians involved in the direct care of individuals with cancer will be provided with details of the risk stratification model. Health care commissioners will be provided with aggregated cancer intelligence data on the number of survivors currently being seen at each NHS Trust according to risk stratification group, so future services can be planned effectively (June 2018).
Data will be held for as long as the research project is funded to undertake this piece of epidemiological and applied health research. Though work is currently planned until December 2019, the current funding expires on 31st August 2017. Subject to securing ongoing funding, the data would be retained until December 2019 to allow sufficient time for completion of analyses, submission and final publication of papers.
Processing:
NHS Digital has previously supplied a pseudo-anonymised HES extract containing details of all inpatient episodes for patients in the Yorkshire and Humber SHA area only under the age of 46 at admission for the period from 1996/97 to 2010/11. A further extract for the period 2011/12 to 2016/17 (latest available) will be supplied and added to the previously supplied extract. These pseudo-anonymised HES extracts are specifically required for comparison of the cohort with the general population of Yorkshire.
The University of Leeds stores the data on an encrypted secure area network (SEED) and access is restricted to individuals working on the YSRCCYP register research programme. Access to the record level data will only be by substantive employees of the University of Leeds and located within the Division of Epidemiology and Biostatistics. No NHS Digital data will be transferred outside of the University of Leeds or shared with any third party individual or organisation (apart from where stored at 2 disaster recovery sites at the University of York and Iron Mountain, where data will be stored only for the purpose of disaster recovery and not processed for any other purpose)
Cohort linked data (HES and mental health), provided under a separate Data Sharing Agreement (reference: DARS-NIC-11809-H1Y3W), and the pseudo-anonymised HES extract are stored in separate files and are distinct from the YSRCCYP data itself. The pseudo-anonymised HES extract will not be linked to the cohort data supplied by NHS Digital or in the YSRCCYP database. Different pseudonymised HES IDs will ensure this is not possible.
On receipt of pseudo-anonymised data (HES and mental health) the YSRCCYP research team undertake the following processing activities:
The pseudo-anonymised HES extract is used to calculate the admission rates (per 100,000 per year) for the same HES diagnoses as the patient cohort. This work has been completed for cardiovascular diseases (van Laar et al, British Journal of Cancer 2014) and for a descriptive piece of health services research as part of a PhD doctoral thesis (Althumairi, University of Leeds, 2017). Work to examine respiratory outcomes according to patient characteristic groups, such as age group, sex, ethnic group, calendar period in the Yorkshire region will be carried out and these data will provide the background rate in the general population.
Rates of admission within the cancer survivors have previously been compared to aggregated hospital admission rates to work out standardised hospitalization admission ratios and assess whether these differed according to cancer diagnosis, treatment, ethnic group, gender, age group, period of diagnosis and socioeconomic status, using statistical models adjusting for patient case-mix while also incorporating the general background hospital admission rates. (Althumairi, University of Leeds, 2017). This process will be repeated using the latest pseudo-anonymised HES extract with a focus on specific disease groups, including respiratory diseases and mental health data, using a similar methodology as the YSRCCYP research team’s previously published work on cardiovascular disease.
The pseudo-anonymised HES extract will be used to compare (but not link) inpatient hospital admissions for the general population in Yorkshire under the age of 60 to data on a population of the same age range in the cohort who were diagnosed with childhood or young adult cancer (derived from data provided under a separate Data Sharing Agreement (reference: NIC-11809-H1Y3W)). The aim is to assess whether certain hospital admissions are more (or less) common amongst a population of survivors of childhood and young adult cancers following treatment compared to the general population. The risk of admissions of a certain diagnosis in the cancer population will be compared to that in the general population. The YSRCCYP research team aims to look at the whole admission pattern of patients, not simply those that occur in the primary diagnosis fields and therefore require an episode level extract as opposed to aggregated counts of admission.
Summaries of the results will be presented orally at conferences and are intended to be published in academic or medical journals. All outputs will be aggregated with small numbers suppressed and in line with the HES Analysis Guide.
Researchers who are not substantively employed by the University of Leeds may apply for access to data from the YSRCCYP but data supplied by NHS Digital will not be shared with any third parties.
Data will only be used for the purposes described in this statement. The NHS Digital data will not be linked to any other data apart from YSRCCYP data.
The YSRCCYP research team requires data from the full period from 1996/97 to 2016/17 (latest available) for several reasons. Firstly in order to address aim 1 investigating changes in levels of hospitalisation over time and within specific cancer types, age groups and sociodemographic groups. Secondly to maximise statistical power for analyses given the rarity of childhood and young adult cancer; also to assess changes in access over time to specialist cancer care services, as NHS policy regarding the recommendations for treatment of children and young people with cancer has changed with the opening of Principal Treatment Centres in hospitals across in England throughout this time frame.
Evaluating clinical care pathways and time to diagnosis also require data of all admissions prior to cancer diagnosis. The late health effects for childhood and young adult cancer survivors may occur any time after treatment ends and the risk of late effects increases as the cohort ages. In order to fully evaluate the total burden of adverse health events in these survivors’, data are required for as long a time period as possible. This may also include any hospital admissions prior to the patient’s cancer diagnosis to identify any underlying health conditions. The YSRCCYP research team is also notified about any subsequent malignant neoplasms from the National Cancer Registration and Analysis Service prospectively following the original cancer diagnosis and therefore need to retain all historical HES and mental health data in order to scrutinise any such individual’s history of hospital admissions and understand potential reasons for those who experience multiple tumour diagnoses.

The Role of Patient-Reported Outcome Measure (PROMs) in the Prediction of Late Cancer Outcomes (Survival)
The following is a summary of the aims of the research project:
To determine whether the automated analysis of PROMs adds predictive value to routine healthcare data when predicting cancer survival. The study team want to understand what information in the PROMs may be useful to develop a machine learning model that predicts survival.
The following NHS England NDRS NCRAS Data will be accessed:
NDRS Cancer Registrations- necessary to understand the survival of patients who have completed the Quality of Life of Colorectal Cancer Survivors in England Survey
NDRS Quality of Life of Colorectal Cancer Survivors in England Survey- necessary to determine the predictive value of PROMS.
The level of the Data will be:
Pseudonymised

This project is scheduled for discussion (both during the analysis stage and when finalised) with patients and public groups (for example, the Bowel Cancer Intelligence Patient Group) to gain the views of cancer patients and their families. Currently, the project has been discussed with a panel of patient representatives at the CRUK RadNet Leeds Patient Dragons Den event, and with patients and the public at a useMyData webinar on AI & Patient Data. The patients have voiced support for the utilisation of PROMs to improve patient outcomes.
Expected Benefits:
The findings of this research study are expected to contribute to evidence-based decision-making for policymakers, local decision-makers such as doctors, and patients by informing best practice to improve the care, treatment, and experience of health care users relevant to the subject matter of the study.
The work carried out in this project will explore and identify the contribution of this PROMs data to understanding the effect on the patients survival as an outcome. It will investigate whether information provided in the PROMs correlates to better or worse outcomes. The potential benefits include:
expanding the understanding of the health and care needs of cancer patients
helping to inform decisions on how to effectively allocate and evaluate funding according to health needs
providing a mechanism for checking the quality of care
facilitating the routine use of PROMs will allow for the co-production of health care pathway, with the benefit of dealing with unmet need and enhancing quality of life
It is hoped that through publication of findings in appropriate media and presenting to patient and researcher forums, the findings of this research will add to the body of evidence that is considered by the organisations and individual care practitioners charged with making policy decisions for or within the NHS or treatment decisions in relation to specific patients.
Additionally, the outputs may lead to informed optimisation of clinical care pathways through patient centred care. This research has the potential to give evidence of the importance and the means to incorporate the patient voice within overall clinical policy and decision making.
The study team have already engaged with Cancer Research UK (CRUK) RadNet Leeds and useMYdata in relation to this project, and intend to make use of these connections when it comes to disseminating the findings of the study.

Objectives:
University of Leeds (UoL) and University College London (UCL) require access to NHS England data for the purpose of the following research project: Enhanced Liver Fibrosis (ELF) test to Uncover Cirrhosis as an Indication for Diagnosis and Action for Treatable Events (ELUCIDATE).
The following is a summary of the aims of the research project provided by University of Leeds:
"The purpose of this study is to assess the potential benefits of biomarkers in liver and renal disease (such as being able to detect and treat disease earlier) for patients and the NHS. Biomarkers are naturally occurring substances that can be measured, often in fluids such as blood or urine, and which provide information about a patient and their illness.
"In our study we are interested in 3 particular biomarkers, together called the Enhanced Liver Fibrosis or ELF test. The ELF test is a blood test that gives information about liver disease.
"The ELF test is being researched to find out whether or not it can be used for the early detection of cirrhosis. A sample of blood will be taken and analysed using the ELF test from patients every 6 months for 30 months. In this study we are trying to find out if using the ELF test to give early warning of liver damage (cirrhosis) can enable us to reduce the risk of developing later major complications of liver disease (like bleeding, liver failure, or cancer).
"The study team requires access NHS England data in order to carry out a long-term follow-up analysis for the trial investigating whether the use of serum markers of liver fibrosis result in patient benefit through improved survival and reduced liver-related morbidity and mortality."
The following NHS England data will be accessed:
Hospital Episode Statistics
o Admitted Patient Care
o Accident & Emergency
o Critical Care
o Outpatients
Emergency Care Data Set (ECDS)
Civil Registration Mortality
Cancer Registration
These data are necessary to determine the incidence of outcomes in the two arms of the ELUCIDATE trial, to measure the effectiveness of ELF guided management of Chronic Liver Disease (CLD) and to determine the cost-effectiveness of this strategy.
The level of data will be:
Identifiable necessary because a specific field (attendance number) is required to enable health economist analysis to see how many GP referrals are made against patients with liver cancer.
The data will be minimised as follows:
Limited to a study cohort of 1,279 patients who consented to participate.
Limited to data between 2010/11 to latest available for all study participants. The primary endpoint is time-to-event, where event is a severe liver-related complication. The more events the study are able to capture, the greater the power of the randomized controlled trial. Therefore, UoL & UCL need data sets that cover the time period from when the active trial closed to current period.
UoL is the research sponsor, and UCL is the employer of the chief investigator. Additionally, both UCL and UoL also employ co-chief investigators for this study. Both UoL and UCL are joint controllers as the organisations responsible for ensuring that the data will only be processed for the purpose described above.
The lawful basis for processing personal data under the UK GDPR is:
Article 6(1)(e) - processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller;
The lawful basis for processing special category data under the UK GDPR is:
Article 9(2)(j) - processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law which shall be proportionate to the aim pursued, respect the essence of the right to data protection and provide for suitable and specific measures to safeguard the fundamental rights and the interests of the data subject.
The public interest for processing these data is to establish the clinical outcomes for participants in the ELUCIDATE study 10 years after enrolment in order to determine the effectiveness of using the Enhanced Liver Fibrosis test to detect cirrhosis and initiate interventions to detect and treat portal hypertension and liver cancer.
The funding is provided by the Royal Free Charity and the University of Leeds. The funding is specifically for the study described.
National Institute for Health and Care Research (NIHR) funded the active phase of the study. The funding ended on 31/12/2015. However, UoL is required to provide NIHR with a report of their findings at the end of the study.
The funder(s) will have no ability to suppress or otherwise limit the publication of findings.
Amazon Web Services (AWS) is a processor acting under the instructions of UCL. AWS role is limited to secure back-up of data stored in UCLs Data Safe Haven.
UCL uses offsite data centre services provided by VIRTUS data centre. VIRTUS does not have access to the data.
Microsoft Azure Cloud is a processor acting under the instructions of UoL. Microsofts role is limited to secure back-up of data stored in UoL. This is co-managed via an external contract with ANS Group Limited.
Data will be accessed by an academic researcher with an honorary contract with UCL. The individual will act as an agent of UoL at all times under supervision from employees of UoL & UCL.
A Public and Patient Involvement and Engagement group helped refine the purpose of the research. The group strongly supported the collection of the data for the purposes described above. In recognition many of the critical outcomes would not accrue without the active study of 3 years necessitating the of long-term follow-up.
Public and Patient Involvement and Engagement involvement was sought again for permission to complete the long-term follow-up of the original study. PPIE representatives supported the original inclusion of the request for permission to follow up the participants using their NHS numbers to interrogate routine data sources for health and care outcomes. As part of the development of this request, the study obtained support from different PPIE representatives (necessitated due to the passage of time and death of the original PPIE partners).
Outputs:
The expected outputs of the processing will be:
· A report of findings to the ELUCIDATE steering committee at completion of the analyses or at 1-year.
· Submissions to peer reviewed journals within 18 months of the data being provided to the investigators.
· Presentations at the International Liver Congress (European Association for the Study of the Liver) and The Liver Meeting (American Association for the Study of the Liver).
The outputs will not contain NHS England data and will only contain aggregated information with small numbers suppressed as appropriate in line with the relevant disclosure rules for the dataset(s) from which the information was derived.
The outputs will be communicated to relevant recipients through the following dissemination channels:
· Journals made available through UCL and UoL website
· Social media
· Public reports
· Posters displayed at national and international liver congresses
· Press/media engagement
· Public promotion of the research through NIHR website
· Participant newsletters
· Reports aimed at participants and research collaborators.
The target date for publication of the results of the analysis of the effectiveness of the use of the ELF test to guide management of cirrhosis in CLD (the primary outcome of ELUCIDATE) will be within 18 months of transfer the data from NHS England.
Processing:
UoL will transfer data to NHS England. The data will consist of identifying details NHS Number, Date of Birth, Postcode & Study ID for the cohort to be linked with NHS England data.
NHS England data will provide the relevant records from the HES, ECDS, Cancer Registration and Civil Registration Deaths datasets to UoL. The data will contain no direct identifying data items but will contain a unique person ID (study ID) which can be used to link the data with other record level data already held by the recipient.
UoL will extract a subset of the data and securely transfer this to UCL. The level of data to be shared will be pseudonymised, including no participant identifiers.
The UCL Data Safe Haven provides the server infrastructure for UCL. The Data Safe Haven is located across two data centres, both operated by UCL.
The respective datasets will be stored on servers at the UoL and the Data Safe Haven for UCL.
Amazon Web Services provides cloud hosting services to UCL and will store the data as contracted by UCL.
The Clinical Trials Research Unit (CTRU) server infrastructure is split between two geographically diverse datacentres on the main UoL campus. Backups are taken from this infrastructure to a separate on-campus datacentre then replicated to the UoL colocation facility in a commercial datacentre (ANS Group) on the other side of Leeds City centre. A monthly copy of the data is also securely transmitted to the UoL Microsoft Azure tenant and co-managed via an external contract with ANS Group Limited.
The data will be accessed by authorised personnel via remote access. The data will remain on the servers at UoL and UCL at all times.
The data will not leave England and Wales at any time.
Aside from this individual, access is restricted to employees or agents of UoL & UCL who have authorisation from the Principal Investigators.
Barts Health NHS Trust is not permitted to access the data.
All personnel accessing the data have been appropriately trained in data protection and confidentiality.
The data will be linked at person record level with HES datasets, Civil Registration Deaths Data and Cancer Registration Data obtained from NHS England.
There will be no requirement and no attempt to reidentify individuals when using the data.
Researchers from the CTRU (based at UoL) and the UCL will analyse the data for the purposes described above.

Objectives:
The University of Leeds requires access to NHS England data for the purpose of the following research project: ALlergy AntiBiotics And Microbial resistance - ALABAMA Study to look at individual patients enrolled in a randomised controlled trial, with a nested-pilot study, of penicillin allergy de-labelling in primary care, the Penicillin allergy status and its effect on antibiotic prescribing, patient outcomes, and antimicrobial resistance (ALABAMA) study.
The following is a summary of the aims of the research project provided by the University of Leeds:
''The primary objective is to determine whether the Penicillin allergy assessment pathway (PAAP) intervention is clinically effective in increasing the proportion of patients prescribed penicillin to treat conditions where a penicillin is the first-line recommended antibiotic.
Half of penicillin allergic patients who have been enrolled in ALABAMA, were randomised to PAAP and the other half were randomised to usual clinical care. Patient outcomes in the PAAP group will be compared with the outcomes of the patients randomised to usual care (up to 12 months after enrolment).
The secondary objectives are to determine whether the PAAP intervention is clinically effective in improving patient health outcomes compared to usual care. Patient outcomes will include total antibiotic prescribing, hospital admissions and length of hospital stays, mortality rates and healthcare costs.
The aim of the ALABAMA study is to find out if people with a penicillin-allergy record in their GP health records have a true allergy by carrying out specialist testing. This will allow ALABAMA to reduce the number of patients wrongly labelled as penicillin allergic and investigate if such testing leads to better use of antibiotics and improved patient outcomes. NHS England Data will be used in the study to address the secondary objectives relating to length and of number of hospitals stays, mortality and cost effectiveness.
The nested pilot trial was used to assess the safety, acceptability, and practicality of delivering the (PAAP).
DATA REQUESTED
The following NHS England Data will be accessed:
Hospital Episode Statistics (HES)
- Admitted Patient Care (APC), Critical Care (CC), Outpatients (OP) and Emergency Care Data Set (ECDS) are necessary to derive estimates of costs associated with hospital care and of hospitalisations and number and duration of hospital admissions, and inform the cost-effectiveness evaluation. HES APC will also be used to identify participants who require a secondary care notes review to enable the trial team to identify any prescription of antibiotic medication participants may have received in hospital.
- Civil Registration Deaths is necessary to derive the rate of death and number of years participants are alive from the start of the study to the date of death or end of study follow-up date, whichever occurs first. The number of years participants are alive will be used in the cost effectiveness analysis. The Data provided by NHS England will be verified against any data received from the other sources. In the event of a discrepancy, the Data provided by NHS England will be included in the analysis
- Medicines Dispensed in Primary Care (NHSBSA) necessary to give a more complete measure of the antibiotic prescribing and be used to inform the effectiveness of the PAAP. These Data will be used to conduct additional cost-effectiveness analysis using dispensed, as opposed to prescribed, antibiotic medications, as dispensed medications may be more relevant measure of NHS resource use. This Data will also provide intelligence about the safety and effectiveness of a penicillin de-labelling process to improve antimicrobial stewardship.
The level of the Data will be identifiable and is necessary to able linkage of data collected from other sources, including the participant themselves and participating sites.
DATA MINIMISATION
The Data will be minimised as follows:
- Limited to a study cohort identified by the University of Leeds for a cohort of participants who are consented to take part in the ALABAMA study.
- Limited to Data from date of randomisation for each individual participant.
- Medicines Dispensed in Primary Care will be limited to antibiotics.
DATA CONTROLLERSHIP
The University of Leeds is the research sponsor and the controller as the organisation responsible for ensuring that the data will only be processed for the purpose described above.
GDPR LEGAL BASIS
The lawful basis for processing personal data under the UK GDPR is:

GPs participating in the study complete an electronic referral within SystmOne to the study team ALABAMA Unit for each consented participant. Consented participants primary care electronic health records can then only be accessed by authorised members of the study team within the secure NHS Health and Social Care Network (HSCN) computer network.
PATIENT AND PUBLIC INVOLVEMENT
A Public and Patient Involvement and Engagement (PPIE) group was convened to help refine the purpose of the research. The group supported the collection of the data for the purposes described above. This included working with four PPIE contributors from early design and will continue through to dissemination, implementation, and NHS adoption.
The PPIE involvement has provided a unique perspective on penicillin allergy and has helped to define the research question to ensure it is relevant to the patient population. Specific examples of their ongoing involvement include providing a PPIE perspective on draft publications, topic guides for interviews to develop educational material and other trial materials submitted for ethics approval. They also have ensured that the inclusion criteria is broad and included patient groups that are high antimicrobial users.
COMMERCIAL INVOLVEMENT
The Phoenix Partnership (TPP) is a not-for-profit industrial collaborator in the project and there is a contract in place with the University of Leeds. TPP provide an advisory role to the study team and support the implementation of the reports used to identify participants for the ALABAMA study and have set up the "ALABAMA Unit" in SystmOne to support delivery of the study. There is a potential commercial benefit to TPP which operates SystmOne, an electronic medical record system whose functionality is used in the study. This potential benefit could stem from positive publicity linked to their involvement in the study. It could inform NICE guideline development and potentially influence the choice of clinical computer system chosen by primary care providers. TPP have agreed to knowledge transfer with their competitors (free of charge) regarding how SystmOne functionality has been used.
TPP will be involved in publications and outputs relating to aspects of the research methodology pertaining to the study teams use of SystmOne.
Expected Benefits:
Expected Benefits relating to Health/or Social Care.
The findings of this study are expected to contribute to more selective use of second line antibiotics throughout the NHS, thereby limiting opportunities for resistance to these treatments to develop and thus safeguarding the effectiveness of what is a limited resource.
Expected Benefits to patients.
Previous studies indicate that most of patients with a penicillin allergy label (90% or more) are not truly allergic and therefore receive unnecessary complex, expensive second-line antibiotics associated with inferior health outcomes. Since second line antibiotics are associated with more complications, including the occurrence of Clostridium difficile, higher risk of treatment failure and need for additional antibiotics than penicillin, most patients with penicillin allergy labels are expected benefit directly from our proposed use of the data.
ALABAMA propose to use the data to measure the effects of PAAP, a one-stop-efficient allergy testing service that seeks to fill the gap left by lack of current allergy service capacity to meet demands of patients for allergy-testing but have currently not service to turn to on an elective basis.
Current eHR labelling assumes an allergy persists for life and there is a lack of adequate coding to consistently revert the exclusion of penicillin's in those tested and found to have a false label. The ALABAMA study will deliver solutions for these shortfalls. The timescale to onset of these benefits is Year 1-3 post-programme end in April 2024.
How outputs will lead to Public Benefits.
These benefits will be achieved by first, demonstrating how PAAP testing can be done to identify patients who despite having a record of penicillin allergy can safely be treated with penicillin. Second by providing practices with an electronic search algorithm to identify those most likely to benefit from PAAP in electronic health records free of charge, thus facilitating rollout of PAAP testing across NHS primary care. Third, through generating evidence suitable for NICE and other organisations to produce guideline for testing of penicillin allergy labels among primary care patients.
Targeting pre-emptive pen-allergy testing, only to those most likely to benefit (by having high antimicrobial use) equates to 0.87% of the UK population aged over 18 years (about 425,000 adults), but wider testing is plausible and has potential to benefit all adults with an unsubstantiated penicillin allergy label (~4.6 million).
The algorithms generated by SystmOne will not involve use of any data from NHS England, which is being used to evaluate outcomes in the study and will be excluded from any products generated by the project. Any outputs or evidence of effectiveness using data from NHS England or otherwise will be disseminated in aggregate form, suppressing aggregate data involving small numbers.
Outputs:
The expected outputs of the processing will be:
A final report of findings to NIHR is expected to be published in the NIHR Journal Library before the end of 2024.
Submissions to peer reviewed journals, including separate publications for the main health impact of the intervention, target journal, Journal of Antimicrobial Therapy, a second will report the cost-effectiveness analysis of PAAP, target journal is Value in Health. Both are expected to be published before the end of 2024.
Presentations at the National Health Economics Study Group meeting and International European Association for Clinical Pharmacology and Therapeutics conferences in Public Health and Health Economics, over the years 2024 and 2025.
The production of electronic GP database patient identification reports and ''pop up'' -alerts relating to pen-allergy testing. This will enable development and refinement of the SystmOne/RESEARCHOne GP eHR (Electronic health records) systems that TPP provides for the purposes of identifying patients who may benefit from PAAP.
The patient identification reports patient "tagging" processes and electronic alert processes that the ALABAMA team has developed in collaboration with TPP (provider of SystmOne) will use existing features of TPPs clinical information system software and will be made freely available to users of any clinical system, so they can be developed into new or existing products in use across the NHS.
In addition, information on the PAAP, describing step by step how to manage patients who may be identified by the patient identification reports in eHR systems, will be made publicly available, for use by the NHS, Charities and Academia with the aim of its being adapted and implemented as a new service in routine practice.
The outputs will not contain NHS England Data and will only contain aggregated information with small numbers suppressed as appropriate in line with the relevant disclosure rules for the dataset(s) from which the information was derived.
The outputs will be communicated to relevant recipients through the following dissemination channels within 12 months after the study end, and beyond this timepoint with professional and guideline setting organisations (e.g. the National Institute for Health and Care Excellence [NICE]):
1. Peer reviewed journals, Journal of Antimicrobial Therapy and Value in Health.
2. Dissemination event for patients/ the public, key stakeholders, Trial Steering Committee and Data Monitoring Committee and participating sites to include wider NHS implementation/adoption guidance.
3. Study Summary Reports prepared with Allergy UK, British Society for Allergy and Clinical Immunology (BACSI), commissioners and GP Electronic Health Records (eHR) system providers.
4. Fact sheets summarising study findings to inform NHS immunology/allergy service-Drug Allergy testing for dissemination among NHS specialist Allergy Services.
i. GPs and the Royal College of General Practitioners (RCGP) to transfer knowledge about PAAP and NHS England, Department of Health and professional associations with antimicrobial stewardship policy and practice.
5. Knowledge transfer of the PAAP antimicrobial-allergy testing eHR coding/alerts updates to Health Informatics and GP eHR Providers.
This will take place at two consultation/dissemination events.
6. NICE collaborators working as NICE Guidelines Advisors on Drug allergy and as member of the NICE antimicrobial stewardship committee.
7. Final dissemination event to report research finding to key stakeholders (e.g.-patients/national patient advocates, clinicians, NHS England-commissioners, platform providers participating practices/participants).
8. Plain English summaries for dissemination to wider lay audiences working in collaboration with our PPIE Co-investigator from the Allergy UK National Allergy Strategy Group (NASG) which is an alliance of the professional organisation BSACI (British Society of Allergy and Clinical Immunology), the patient charities, Allergy UK and Anaphylaxis UK.

Expected Benefits:
This programme is expected to provide evidence as to which groups of ED users should be targeted; what kind of interventions should be delivered; how those interventions achieve their desired outcomes; and how outcomes should be measured.
The expectation is that the outputs of this study will reach the health and care system via established links with NHS England, the Royal Colleges of Psychiatry and Emergency Medicine and via direct contact with all frequent user services by a cascading series of webinars as detailed in Expected Outputs.
The findings are hoped to enable UEC networks to make informed planning choices about services for frequent users. The programme team intend to provide best evidence on how interventions work (or fail) in order to guide on-the-ground delivery. The large investment in liaison mental health services (LMHS) over the last 4 years means that NHS stakeholders should be keen to receive evidence of the impact of LMHS on frequent user services. By incorporating patient and public involvement (PPI) in the research, it is expected that awareness of constructive approaches to this important issue will increase.
The findings of this research study are expected to contribute to evidence-based decision-making for policy-makers, local decision-makers such as doctors, and patients to inform best practice to improve the care, treatment and experience of health care users relevant to the subject matter of the study.
The use of the data could:
help the system to better understand the health and care needs of populations.
lead to the identification or improvement of treatments or interventions, or health and care system design to improve health and care outcomes or experience.
advance understanding of regional and national trends in health and social care needs.
inform planning health services and programmes, for example to improve equity of access, experience and outcomes.
provide a mechanism for checking the quality of care. This could include identifying areas of good practice to learn from, or areas of poorer practice which need to be addressed.
The aim is to improve services for UEC frequent attenders by understanding which activities are carried out by services and what difference they make. This is expected to enable us to develop programme theories which includes which aspects of services are important, how they work and which patients they help most. An implementation framework can then be developed to improve services planning and focus on activities likely to bring benefits to the patients.
A Public and Patient Information and Engagement group was consulted regarding the collection of the data for the purposes described above. Two experts by lived experience make up part of the programme team. They attended the design study meetings, commented on all drafts of the study application for NIHR funding and had individual meetings with the principal investigator of the study, contributing to all workstreams of the programme and helping to set up the dissemination strategy.
As part of the study plan, a PPI reference group was set up to follow the progress of the study and assure PPI input in all stages.
To inform and advertise findings to a wider audience and optimise the potential public benefits from the use of the data, the programme team intend to use strong and established links with:
NHS England; the Current Chair of the Faculty of Liaison Psychiatry; the Royal College of Emergency Medicine and its mental health committee; The Association of Ambulance Chief Executives (AACE) who provide ambulance services with a central organisation that supports, coordinates, and implements nationally agreed policy; the Royal College of General Practice; and the European Association of Psychosomatic Medicine to reach a wider European audience.
The principal investigator and experts by lived experience co applicants plan to lead on developing a strategy to inform users and carers on a local and national basis about the findings. The intention is to approach NHS Choices and offer to help with updates as a result of the study.
Outputs:
The main analysis is due to be completed by September 2024 with the aim to disseminate and publish results between November 2024 and February 2025. Results are expected to be published in open access and peer reviewed journals, including publication via the National Institute for Health Research's own journal library, and a paper on Frequent users of the emergency department: improving services and identifying evidence-based interventions-a mixed methods study for submission to other appropriate journals. The analysis of the datasets requested are planned to be presented at research meetings, such as national and international liaison psychiatry meetings. These conference presentations and papers will report aggregated results across patient episodes and the results will be based on statistical analysis generated from the data (typically in the format of tables, graphical representations, and text).
The outputs will not contain NHS Digital data and will only contain aggregated information with small numbers suppressed as appropriate in line with the relevant disclosure rules for the dataset(s) from which the information was derived.
Longstanding and ongoing engagement with stakeholders, including both scientific and policy-making audiences is expected to provide a direct pathway to impact for the outputs of this research. The Experts by Experience in the team should help inform the dissemination strategy and play an active role in the format and content of academic papers, as well as supporting presentation at local, regional, and national conferences and wider stakeholder meetings.
The results and outputs of the study are planned to be communicated further via the study team's websites, social media accounts and through other public promotion of research utilizing the researchers' networks, including clinical networks, scientific networks, and charitable organisations.
The main outputs that are intended to be produced from this study are:
-Characterization of the different patterns of frequent use of UEC services and associated factors; Detailed costs related to the pattern and use of UEC services by frequent users.
-A robust evaluation of the impact of frequent user services including cost-effectiveness.
-Identification of specific interventions for certain sub-types of frequent users and the mechanisms by which they achieve their desired outcomes.
-An understanding of the impact of COVID-19 on frequent use of UEC services.
-Publications of the main research findings/conference presentations, information across different media outlets including the study website, social media (using podcasts and twitter), PPI organisations links, relevant charities.
The programme team plan to use a multi-level approach to transfer information about the study findings to relevant stakeholders. The top-down approach will involve targeting six key groups: NHS England, The Royal Colleges of Psychiatry, Emergency Medicine and General Practice, Ambulance Services, and the NHS Confederation. The intention is to convene a workshop of relevant national stakeholders and PPI representatives to present the findings from the Programme, and to discuss the recommended improvements to services.
At an intermediate level, the plan is to hold 4 webinars (each one focusing on a particular service type) which will be jointly presented by members of the programme team and key personnel from the case site of relevance, and which will be targeted at the frequent user services that participated in work stream 1 of FUsED.
At the bottom-up level, the intention is to hold 4 further webinars which will again focus on a particular service type. All remaining frequent user services would be invited to attend one of the webinars, according to their type of service. It is intended that any relevant feedback from the webinars would be incorporated into the team's implementation framework.
The programme team intend to co-develop with the patient and public involvement (PPI) reference group plain English summaries, voice-recordings and podcasts of findings and make these available online through blogs and social media.

Objectives:
The University of Leeds requires access to National Cancer Registration and Analysis Service (NCRAS) data for the purpose of the following research project: Yorkshire Specialist Register of Cancer in Children and Young People (YSRCCYP). Cancer registration data from the YSRCCYP is used to carry out a programme of epidemiological and applied health research as set out in the Yorkshire Register protocol. The YSRCCYP is a specialist register focusing on tumour registrations diagnosed in the Yorkshire and Humber region since 1974 for patients aged 0-14 years and 1990 for those aged 0-29 years. The YSRCCYP research team, within the University of Leeds, is notified of patients eligible for inclusion in the YSRCCYP either directly by the patients treatment centre or via electronic reports from the NCRAS, the latter covered by this Data Sharing Agreement (DSA).
Childhood cancer registration details for those aged 0-15 years are primarily provided via the two Principal Treatment Centres, at Leeds Childrens Hospital and Sheffield Childrens Hospital, with a secondary source being the NCRAS. For 16-29 year olds, these are primarily provided by the NCRAS, with secondary sources being Teenage and Young Adult Principal Treatment Centres in Leeds and Sheffield. The NCRAS is also the primary source of information for these children and young people if diagnosed with any subsequent tumours or relapses at any age and living inside or outside the Yorkshire region at the time.
The NCRAS dataset also provides data on death registrations for any existing tumour registration since 1974 on an annual basis as part of this annual data extract.
The objectives for this study are:
1) Mortality trends paper examining changes over time and differences according to ethnicity, deprivation and stage,
2) Evaluation of cardio-metabolic fatalities, examining differences according to ethnicity, deprivation, stage and treatment
The following NCRAS data will be accessed with this application (DARS-NIC-656761):
Civil Registration Mortality necessary to calculate survival estimates to examine early mortality and long-term trends in survival for the YSRCCYP cohort.
NDRS Cancer Registration necessary to ensure that the YSRCCYP has complete case ascertainment for all patients aged under 30 years in Yorkshire, as well as any subsequent tumours or relapses.
NDRS National Radiotherapy Dataset (RTDS)
NDRS Systemic Anti-Cancer Therapy Dataset (SACT)
The following datasets will be accessed with the DARS BAU sister application (DARS-NIC-11809):
Mental Health Services Data Set (MHSDS)
Bridge file: Hospital Episode Statistics to Mental Health Minimum Data Set
Hospital Episode Statistics Admitted Patient Care (HES APC)
Hospital Episode Statistics Outpatients (HES OP)
Emergency Care Data Set (ECDS)
The level of the data will be identifiable this is so that University of Leeds can capture key patient fields such as NHS number, full name, date of birth, sex and postcode so that University of Leeds can access the right persons medical records and validate key information such as cancer diagnosis, staging and treatment whilst addressing any missing information. These identifiers are stored and then used to enable data linkage with information collected from other sources such as local Patient Managements systems (PPM), HES, National Pupil Database, Department for Work and Pensions (DWP), HMRC and Patient Reported Outcome Measures (PROMs) data as described in the YSRCCYP data flow diagram, as part of the epidemiological research programme to monitor long-term health and social outcomes.
The data will be minimised as follows:
Limited to data for the YSRCCYP cohort identified by the University of Leeds, i.e. patients aged 0-14 years diagnosed with cancer in Yorkshire & the Humber between 1974-1989 and patients aged 0-29 years since 1990.
All valid ICD10 codes for cause of death.
ICD10 codes C00 C97, D00-D05, D07-D48 for second primary tumours.
The University of Leeds is the research sponsor and the data controller as the organisation responsible for ensuring that the data will only be processed for the purpose described above.
The lawful basis for processing personal data under the UK GDPR is:
Article 6(1)(e) - processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.
The lawful basis for processing special category data under the UK GDPR is:

The NIHR Clinical Research Fellow within the YSRCCYP team, has led on the development of two national Public and Patient Information and Engagement workshops in February 2022 and April 2022 in conjunction with DATA-CAN exploring young peoples views on the use of health data for research purposes. This included discussion around cancer registration and data linkage with education and employment datasets. There was strong support from the group in favour of these ongoing research activities and these findings are being written-up for publication later this year. The workshops also helped to inform the research strategy because the late effects of cancer were also one of the young people's research priorities. These young people are also supporting University of Leeds in individual research projects and grant applications.
The NIHR Clinical Research Fellow and the Register Statistician, have also represented the work of the YSRCCYP and Candlelighters Trust at the Be Curious public engagement event for children and their families held at the University of Leeds in May 2023. This was a huge success with numerous families asking questions about the research and expressing interest about being involved in future PPIE events related to the YSRCCYP. There was significant diversity of families attending the event, for example children attended from the Bradford East family hub along with families where English was their second language. This provided University of Leeds with the ability to engage with the harder to reach populations.
University of Leeds have also engaged with groups such as the GenerationR Young Peoples Advisory Group at Leeds General Infirmary where the research from the YSRCYP is disseminated to young people in accessible forms.
The contract is reliant on the Data Recipient maintaining the continued support for use of confidential patient information without consent, according to regulations made under section 251 of the NHS Act 2006 (20CAG0133).
National opt-outs will be upheld.
Where individuals have opted out of disease registration by the National Disease Registration Service (NDRS), their data has been permanently removed from the registry and therefore will not be disseminated under this Data Sharing Agreement (DSA). https://digital.nhs.uk/ndrs/patients/opting-out
Yielded Benefits:
Multiple peer-reviewed publications describing the epidemiology and long-term outcomes for children and young people diagnosed with cancer in Yorkshire. A full list can be found here: https://ysrccyp.org.uk/research/publications/ Some specific examples: 1) The data collected as part of the YSRCCYP has allowed researchers to better understand the burden on NHS services of late cardiovascular and respiratory morbidity as well as second cancers survivors and quantifies the long-term risk of such morbidity for survivors and healthcare professionals looking after them. It has enabled childhood and young adult cancer survivors and their families to understand more about their own risk of developing these longer-term health problems according to their original diagnosis and treatment, and at what age they are most likely to appear. In effect, young cancer patients have been able to take ownership of their own survivorship. 2) The YSRCCYP database has facilitated the production of an up-to-date summary of the latest literature relating to late consequences of cancer treatment on reproductive health, describing the impact on both fertility and pregnancy. This has provided awareness and information to cancer survivors from Yorkshire about reproductive outcomes to enable them to plan fertility storage at the earliest opportunity and maximise the chances of having their own offspring. Additionally, the identification of a sparsity of evidence on outcomes of ovarian and testicular tissue resulted in establishment of a multi-centre initiative to establish a population based register of individuals with stored ovarian and testicular tissue in the United Kingdom (UK). 3) It has allowed researchers to quantify respiratory morbidities, treatment-related risks and their relationship to subsequent morbidity and mortality among long-term survivors of childhood and young adult cancer in Yorkshire. This information has been made available to the clinical community in Yorkshire in the form of research papers, regular webinars and infographics so that those health professionals looking after young cancer survivors are able to inform them of their risks of morbidity depending on their original cancer diagnosis and treatment, and at what age these are likely to be develop. 4) It has allowed researchers to quantify the prevalence and spectrum of mental health problems found in adult survivors of childhood cancer, based on a systematic review of the current evidence. Problems ranged from depression, anxiety, behavioural problems and drug misuse. Factors increasing the likelihood of mental health problems included treatment with high-dose anthracyclines, cranial irradiation, diagnoses of sarcoma or central nervous system tumours and ongoing physical ill health. The review recommended further work to identify childhood cancer patients who are at risk of developing late mental health morbidity. 5)The first comprehensive analysis of hospital mental health episodes following CTYA cancer treatment (Friend, PhD thesis, 2020), preceded by a systematic review of the current evidence (Friend et al, Int J Cancer 2018). 6)The YSRCCYP research team found that the National Cancer Survivorship Initiative paediatric late-effects risk stratification system can be effectively and safely applied to cancer patients aged 18-29, independent of ethnicity or socioeconomic position. This evidence has supported clinical services in Yorkshire and further afield across the UK to safely adopt risk-stratified care pathways for the long term follow up of individuals living with and beyond cancer.
Expected Benefits:
The findings of this research study are expected to contribute to evidence-based decision-making for policy-makers, local decision-makers such as doctors, and patients to inform best practice to improve the care, treatment and experience of health care users relevant to childhood and young adult cancer.
The use of the data could:
help the system to better understand the health and care needs of the childhood and young adult cancer population in Yorkshire.
lead to the identification or improvement of treatments or interventions, or health and care system design to improve health and care outcomes or experience.
advance understanding of regional trends in health and social care needs.
inform planning health services and programmes, for example to improve equity of access, experience and outcomes for children and young people with cancer.
provide a mechanism for checking the quality of care. This could include identifying areas of good practice to learn from, or areas of poorer practice which need to be addressed.
Potential benefits could comprise:
An ability to evaluate changes in risk of death for children and young people diagnosed with cancer in Yorkshire and determine whether differences exist by ethnic group, deprivation and stage at diagnosis.
Identify those groups of survivors who are most likely to experience the poorest health and social outcomes so that appropriate interventions and improvements in care quality can be devised.
It is hoped that through publication of findings in appropriate media, the findings of this research will add to the body of evidence that is considered by the bodies, organisations and individual care practitioners charged with making policy decisions for or within the NHS or treatment decisions in relation to childhood and young adult cancer patients and survivors in Yorkshire.
University of Leeds will use multiple channels to disseminate key findings. These will include:

Objectives:
Bradford Teaching Hospitals NHS Foundation Trust (BTHFT) and the University of Leeds require access to NHS England data for the purpose of the following research project: "Home-based Extended Rehabilitation for Older people (HERO)" - Individually randomised controlled multi-centre trial to determine the clinical and cost effectiveness of a home- based exercise intervention for older people with frailty as extended rehabilitation following acute illness or injury, including embedded process evaluation
The following is a summary of the aims of the research project provided by the BTHFT and University of Leeds:
"The majority of older people (>65 years) in hospital have frailty and are at increased risk of readmission or death following discharge home. In the UK, following acute hospitalisation, around one third of older people with frailty are referred on for rehabilitation. Although this rehabilitation can reduce early readmission to hospital, recipients often do not feel ready to leave the service on discharge, suggesting possible incomplete recovery. Limited evidence suggests extended rehabilitation is of benefit in several conditions and there is preliminary evidence that progressive physical exercise can improve mobility and function for older people with frailty, and slow progression to disability. The HERO study aim is to evaluate the clinical and cost effectiveness of the Home-based Older Peoples Exercise (HOPE) programme as extended rehabilitation for older people, in a multi-centre individually randomised controlled trial. HOPE is a individualised, graded and progressive 24 week exercise programme delivered by NHS physiotherapy."
The following NHS England data will be accessed: Hospital Episode Statistics (HES) Admitted Patient Care (APC), Outpatient Care (OC), Critical Care (CC), Accident and Emergency (A&E), Emergency Care Data Set (ECDS), and Civil Registration Deaths. This is necessary to establish whether the HOPE intervention: 1) reduces all-cause hospitalisation 2) reduces falls / hospitalisation due to falls; 3) reduces overall health and social care resource use; 4) intervention is cost-effective. The use of routinely collected administrative data is preferred to asking participants or hospital staff to retrospectively account for resource use as the data are detailed, complete, are amenable to costing and much less likely to be missing due to non-response.
Identifiable data will be submitted to NHS England. This is necessary to enable linkage of data with the clinical data (from hospitals) and patient reported outcomes (for the cohort of participants) to derive an analysis dataset for the HERO study. Pseudonymised data will be disseminated back to the Clinical Trials Research Unit (CTRU) at the University of Leeds.
The data will be minimised as follows:
Limited to data for the cohort - approx. 700 participants recruited to the HERO study as identified by BTHT and the University of Leeds. Participants were eligible if they were aged over 65 and admitted to general medicine / elderly medicine or trauma and orthopaedics care following acute illness or injury, who were then discharged home. People had to have mild, moderate or severe frailty, defined using the Clinical Frailty Scale (CFS) and had to be able to provide informed consent.
People were excluded if they were permanent care home residents, had significant cognitive impairments or other medical conditions to preclude participation in the HOPE programme. These included:
- Moderate/severe dementia at baseline* (defined as Montreal Cognitive Assessment test <20).
- Recent (<3 months prior randomisation) myocardial infarction, or unstable angina
- Very severe frailty (defined as score of 8 on CFS).
- Terminally ill (defined as score of 9 on CFS).
- Receiving palliative care
Recruitment took place from between December 2017 and August 2021, from 15 NHS Trusts across Yorkshire and the South-West of England. The NHS Trusts are based in 2 geographical hubs in Yorkshire and the Southwest of England. The trial team are based in these regions and have strong working relationships with the NHS Trusts locally, existing partnerships and shared interest/ expertise in this area of research. The hubs provide scope for diversity in the population recruited to the trial and cover urban and rural areas with different population profiles. This is important to ensure the trial population is representative of the general population to ensure generalisable results.
Data will be provided for each participant from date of randomisation to 12 month + 30 days post randomisation. The additional 30 days will capture NHS activity/discharge date for those participants who were admitted / received care towards the end of the 12 month post-randomisation time window and collect all relevant data relating to the admission to minimise missing/unknown outcomes.
BTHFT and University of Leeds are joint controllers and are responsible for ensuring that the data will only be processed for the purpose described above. BTHFT is the research sponsor. This study is multidisciplinary academic collaboration between the Academic Unit for Ageing & Stroke Research (ASR) based at BTHFT and part of the University of Leeds, the Clinical Trials Research Unit (CTRU) and Academic Unit of Health Economics (AUHE) at the University of Leeds, and the University of Exeter.
The Chief Investigator is Chair of Geriatric Medicine and his substantive employer is the University of Leeds. The CTRU is co-coordinating the trial and is responsible for trial design and conduct, including protocol development, ethics approval, trial monitoring, data collection and ongoing management, and statistical analysis and reporting. The AUHE will perform the cost effectiveness analysis. The geographical hubs are led by ASR and University of Exeter. Each hub has trial managers and clinical co-applicants to co-ordinate set-up, recruitment, data collection and ongoing liaison with sites through the course of the trial.
A contract is in place between the funder (Department of Health) and BTHFT (NHS Lead and sponsor), and a collaboration agreement is in place between the BTHT (Sponsor), the University of Leeds, and the University of Exeter. University of Exeter is neither a controller, nor a processor in regard to data requested under this application and the data controllers are the organisations responsible for ensuring that the data will only be processed for the purpose described above.
The lawful basis for processing personal data under the UK GDPR is:
Article 6(1)(e) - processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.
The lawful basis for processing special category data under the UK GDPR is:
Article 9(2)(j) - processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law which shall be proportionate to the aim pursued, respect the essence of the right to data protection and provide for suitable and specific measures to safeguard the fundamental rights and the interests of the data subject.
The trial is funded by the NIHR Heath Technology Assessment (15/43/07). The trial funder does not make decision on the processing of personal data, and has no role in study design, data collection, data analysis, data interpretation, or writing of the final report. The funding is specifically for the HERO trial and funding is in place until May 2023.
Patient and Public Involvement and Engagement (PPIE) is provided via representation on oversight groups, and the NIHR Applied Research Collaboration (ARC) Frailty Oversight Group (FOG). The data collection processes were discussed at the grant application stage, and this was scrutinised by the Frailty Oversight Group (FOG) at NIHR ACR which includes PPIE representation. The protocol was finalised in collaboration between the Trial Management Group (TMG) and Trial Steering Committee (TMC), both committees include PPIE representation. The PPIE representatives on the TMG have included a patient representative who was in her late 70's and frail herself, and 2 representatives from Carers' resource, both professionals working very closely with carers whom are frequently adults caring for older adults with frailty. Our TSC PPIE representatives included an older adult with frailty, and a director from a local branch of Age UK. FOG meet at least quarterly and is made up of older adults and carers, many of whom have varying degrees of frailty.
Expected Benefits:
The majority of older people (>65 years) in hospital have frailty and are at increased risk of readmission or death following discharge home. In the UK, following acute hospitalisation, around one third of older people with frailty are referred on for rehabilitation, termed intermediate care services (Reference: A whole system study of intermediate care service for older people. Age Ageing. 2005;34(6):57783).
Although this rehabilitation can reduce early readmission to hospital (<30 days), recipients often do not feel ready to leave the service on discharge, suggesting possible incomplete recovery. Limited evidence suggests extended rehabilitation is of benefit in several conditions and there is preliminary evidence that progressive physical exercise can improve mobility and function for older people with frailty, and slow progression to disability.
HERO will evaluate the effectiveness of the Home-based Older Peoples Exercise (HOPE) programme as extended rehabilitation for older people with frailty discharged home from hospital or intermediate care services after acute illness or injury. If HOPE is found to be effective, it could be used to inform policy changes to improve mobility and function for older people with frailty. The trial team will development an implementation pack or toolkit to support the implementation of the trial findings. This would be communicated to NHS England, through the National Clinical Director for Frailty and disseminated to Integrated Care Boards to support future commissioning of services for older people in the UK. This has the potential to improve care & quality of life of older people and if shown to be cost-effective, reduce the cost burden for the NHS & social care. The anticipated date of this benefit is late 2023 when the analysis completes. The cost consequences of different treatment decisions is a fundamental part of the health economic evaluation. A requirement to understand the counterfactual cost expectations in absolute terms if one treatment is used compared to the other. It will enable to explore the cost-consequences from both a payer (NHS and PSS) and wider-societal perspective and this will of course include secondary care costs which are derived from combining HES and national cost data and primary care costs which include self-reported resource use combined with national sources of costing (e.g. PSSRU). It will enable and hopefully result in the distribution of cost burden across the agents involved in the decision including patients, social care and the NHS.
Outputs:
The analysis and publication is due to be completed by Summer 2023 (subject to availability of data). The dissemination strategy will be co-developed by the research teams patient/carer led Frailty Oversight Group;
Specific planned outputs include:
Publication(s) in open access journals, including the NIHR journal series and peer reviewed international general medical journal(s);
Press releases, for example through the British Geriatrics Society press office;
Presentations and local and international conferences;
Presentations and informal discussion at voluntary agency events, and contributions to local community group newsletters,
A lay summary to be provided to all participants, and their carers;
A lay summary for the trial website, and other platforms, including Twitter;
Summaries for therapists and participating research teams;
Resource to support commissioning, including an Implementation toolkit consisting of intervention materials, training materials, and a mechanism to measure impact.
A derived dataset, for evaluation, teaching and training purposes relating to the provision of NHS care and treatment, and for academic and non-commercial research purposes (subject to further approval from NHS England).
Processing:
The trial statistician at the CTRU will provide the following identifier for each participant:
NHS Number.
Study ID
Gender
Date Of Birth
Postcode
For each participant, the data request will be for a date the participants were randomised up until 12 months and 30 days post randomisation. This will provide assurance that minimum data required is obtained. The last randomisation was August 2021, and therefore the data request will be up to and including September 2022 for the last participant randomised to the trial.
NHS England will perform an automatic cohort tracing system to search the data provided against existing electronic records to generate a set of records that belong the cohort of 701 trial participants. This will include linkage of data from Hospital Episode Statistics (HES) Admitted Patient Care (APC), HES Critical Care (CC), HES Outpatients, Emergency Care Data Set (ECDS), HES Accident & Emergency (A&E) and Civil Registration (Deaths) Secondary Care Cut. The period request for the HES data will be from 17/18 annual data, up until September 2022 data, in addition to Civil Registration Deaths. This will be be provided to allow linkage of the NHS England data to the trial data held by the CTRU. NHS England will return pseudonymised data linked using the CTRU supplied Study ID.
To enable the analysis to take place the data will be identified by Study ID number but will be stored separately to other patient identifiable data. The data therefore is pseudonymised.
Data flowing from NHS England will include, Study ID, HES and mortality record level data to the trial statistician, via a Secure Electronic File Transfer (SEFT). On receipt of data from NHS England, the trial statistician will transfer the data into a secure folder prior to using in statistical software for analysis. Pseudonymised data are made available on the CTRU secured servers for processing by the Health Economist.
The statistical analysis will be conducted within a statistical software package in accordance with a Statistical Analysis Plan which will be finalised and agreed by the TMG. For the analysis of the outcome related to hospital readmission an indicator will be derived for each participant to indicate whether or not they experienced a readmission. The number (proportion) of participants experiencing readmission will be compared between study arms using a partially nested logistic regression mixed effects model (accounting for clustering in the intervention arm only) which will include trial data held by CTRU.
A similar approach will be used to analyse outcomes related to all-cause hospitalisation and hospitalisation due to falls. The Health Economics Analysis Plan will be conducted in accordance with the Health Economic Analysis Plan (HEAP) which will be agreed by the lead health economist on the trial. The health economic evaluation will involve a within-trial cost-effectiveness analyses and long-term decision-analytical model. Information on health resource use and mortality will be sourced from NHS England data.
There will be no record level data transferred from CTRU for the purpose of economic evaluation. The within-trial and decision analytic model require only population-averaged expectations of Health Related Quality of Life (HRQoL) and cost generation over time. These parameters will be estimated within CTRU and provided to the health economic modelling team. These parameters are those that would be typically presented in a report and would be acceptable to be placed in the public domain. The outputs will only contain aggregated information with small numbers suppressed as appropriate in line with the relevant disclosure rules for the dataset(s) from which the information was derived.
Data will only be accessed and processed by substantive employees of the University of Leeds and will not be accessed or processed by any other third parties not mentioned in this agreement. Data will be stored at the CTRU (Organisation Data Service (ODS) is ECC0010). No record level data disseminated via NHS England for this application will flow from the University of Leeds.
The CTRU server infrastructure is split between two data centres on the main University of Leeds campus. Data on CTRU servers is encrypted to AES 256 with access restricted to just CTRU server admins. The ability to decrypt is only held by the CTRU.
Only aggregated data with small numbers suppressed will be made publicly available. No third party will have access to the data. Data will not be used for any other purposes, and it will not be used for commercial purposes, nor for direct marketing purposes.
Following analysis, publication and dissemination, if needed, the data will be retained, under a valid Data Sharing Agreement, with no further data being requested, to allow compliance with good clinical practice and regulations. This will allow verification of results or audit by the sponsor (or delegate).
There will be no data linkage undertaken with NHS England data provided under this agreement that is not already noted in the agreement.

Objectives:
The University of Leeds requires HES and mental health data for a specific cohort to be used, alongside data collected in the Yorkshire Specialist Register of Cancer in Children and Young People (YSRCCYP), to continue its epidemiology and health services research programme.
For background, the YSRCCYP is a regional population based register containing detailed demographic and clinical information on children and young adults aged 0-29 years diagnosed with cancer since 1974. The YSRCCYP covers the Yorkshire and Humber Strategic Health Authority (SHA) which has a total population of 5 million people. Spanning an area of 15,000 square kilometres the Yorkshire and Humber SHA comprises a range of urban and rural communities with a significant ethnic minority population resident in parts of West Yorkshire.
The YSRCCYP research team, within the University of Leeds, is notified of patients eligible for inclusion in the YSRCCYP either directly by the patient’s treatment centre or via electronic reports from the National Cancer Registration and Analysis Service. The YSRCCYP research team then obtains information on patients by manual data abstractions from hospital records. Detailed data on the patient and diagnosis, including treatment information for each of these cases is obtained by a sole data collection officer via the medical records at relevant hospitals in the area, and annual follow up of all cases takes place to ascertain data on any relapses or deaths through letters sent either to the patient’s treating consultant or general practitioner. Data on 9,500 patients have been collected since 1974, however linked HES and mental health data was required for only 8,500 as the cohort shared with NHS Digital excludes participants who passed away before 1996. The cohort submission under approval of this request will consist of approximately 7,000 patients.
The YSRCCYP was originally set up in collaboration with local clinicians to provide research information. Since 1994, the YSRCCYP database and research programme has been managed by and at the University of Leeds’ Division of Epidemiology & Biostatistics. The University of Leeds is the Data Controller for the YSRCCYP with sole responsibility for determining the purposes for which and the manner in which any personal data are processed. The work is currently funded by the Candlelighters Trust.
The purpose of the YSRCCYP is to facilitate population-based epidemiological and health services research. The use of HES and mental health data contributes to this by providing additional information that can be linked with and analysed with data from the YSRCCYP data. The HES and mental health data are not added into the YSRCCYP research database. The two datasets are stored separately but contain common unique study IDs enabling data to be linked at record level. Where required for specific research, relevant data are extracted from the respective databases, linked and analysed by the YSRCCYP research team.
A current research focus is on hospital burden around the time of diagnosis and treatment and monitoring long term risks of hospitalisation associated with cancer treatment. One specific processing activity will relate to describing the risks and prevalence of mental health illness within the cancer cohort compared to the general population.
This type of epidemiological and health services research has the potential to benefit future patients by identifying risk factors which can be used by health professionals to identify those at greatest risk of mental health illness so that interventions and appropriate support can be implemented. It may also reveal important environmental risk factors, examine changes in incidence rates which may help to identify possible causes and understand survival patterns according to ethnic group and socio-economic status in order to ensure that there are no inequalities in outcomes or access to specialist cancer care for certain sub-populations.
The YSRCCYP research team’s research plans include the following objectives:
1) To describe the total burden of hospitalisation among the Yorkshire cancer population aged 0-29 years, to identify clinical and sociodemographic factors which influence the likelihood of hospitalisation and to investigate how hospitalisation rates have changed since 1997.
2) To understand patient care pathways through the NHS before, during and after cancer diagnosis. This includes assessment of time to diagnosis for children and young adults diagnosed with cancer under the age of 30 years to identify where improvements can be made to minimise delays in diagnosis leading to better prognosis and less stress and anxiety on patients and their families.
3) To calculate the risks and costs to the NHS of adverse health events requiring hospital admission for survivors of cancer in this age group so that clinicians can provide appropriate follow-up care.
To address aim 1 above the YSRCCYP research team will utilise HES and mental health data to investigate long term risks of respiratory and mental health illness in the cohort and identify sociodemographic and clinical factors which may affect these risks. The YSRCCYP research team also wish to determine the relative excess risk of these conditions within the cancer cohort compared to the general background population and, in order to make this comparison, requires a separate pseudo-anonymised extract of HES data containing all episodes for patients in the Yorkshire and Humber SHA area only under the age of 60 at admission (the oldest person currently registered). This separate extract is covered under a separate Data Sharing Agreement (reference: NIC-155843-0MQMK).
The YSRCCYP research team require some data items classed as sensitive. These are the Referrer code, which indicates the manner in which the patient was referred to hospital by ascertaining the code of the referring organisation. This allows the YSRCCYP research team to identify particular patient pathways which are associated with an optimal time to diagnosis, a key indicator known to influence survival. Additionally the Consultant code data field is required because it enables the YSRCYYP research team to work out whether patients receive care at specialist cancer centres as opposed to general district hospitals, in order to address important health services research questions such as: ‘Does specialist care improve patient outcomes for children and young people including length of hospital stay and reduce subsequent morbidity and mortality?’. There are currently no databases which link consultant codes to specialist cancer centres for childhood and young adult cancer, so this process needs to be done manually using cohort linked NHS Digital data and the YSRCCYP database.

iii. Yielded Benefits : The YSRCCYP database has yielded several benefits, for example: • The data collected as part of the YSRCCYP has allowed researchers to better understand the burden on NHS specialist services of late cardiovascular and respiratory morbidity as well as second cancers in relation to childhood and young adult cancer survivors and quantifies the long-term risk of such morbidity for survivors and healthcare professionals looking after them. • The YSRCCYP database has facilitated the production of an up-to-date summary of the latest literature relating to late consequences of cancer treatment on reproductive health, describing the impact on both fertility and pregnancy. • It has allowed researchers to quantify respiratory morbidities, treatment-related risks and their relationship to subsequent morbidity and mortality among long-term survivors of childhood and young adult cancer in Yorkshire. By age 40, cumulative incidence for an admission for any type of respiratory condition was almost 50%. Respiratory admission rates were almost 2 times higher in cancer survivors than in the general population. Treatment with chemotherapy with known lung toxicity increased the risk of admission for all respiratory conditions. Subsequent mortality was highest in those admitted for pneumonia compared to other respiratory conditions. • It has allowed researchers to quantify the prevalence and spectrum of mental health problems found in adult survivors of childhood cancer, based on a systematic review of the current evidence. Problems ranged from depression, anxiety, behavioural problems and drug misuse. Factors increasing the likelihood of mental health problems included treatment with high-dose anthracyclines, cranial irradiation, diagnoses of sarcoma or central nervous system tumours and ongoing physical ill health. The review recommended further work to identify childhood cancer patients who are at risk of developing late mental health morbidity.
Expected Benefits:
The benefits to health and social care will include:
1. Improved patient care. This work will identify to clinicians, commissioners and patients themselves of those individuals who are at greatest risk of hospitalization; this will enable follow-up practices to be tailored to patient needs, help identify potential health problems early and intervene so that patient wellbeing is maximized and NHS burden minimized. For example, those individuals identified from the risk stratification model as being at greatest risk of mental health illness will be offered additional support from NHS services (e.g. psychiatry, social care) through their treating oncologist or GP. The risks of depression following cancer treatment will help to describe the NHS burden of mental health problems in this vulnerable population. This knowledge will be informative to paediatric oncologists and other allied health professionals caring for patients, as well as their GPs, by improving awareness of the timing when depression is likely to be diagnosed so that the quality of care can be improved. Patients will be informed of their risk group via their treating consultant or at their annual hospital clinic follow up appointment. Their GPs will also be informed of the results of the risk stratification via the hospital consultant team. Anticipated dates to complete these activities are by December 2018.
2. Evaluation of treatments to identify best practice and guidance. Work to understand the reasons for the hospitalisation so researchers can identify whether certain treatments are associated with an increased risk of hospitalisation and disseminate this information through scientific journal articles. This will mean that alternative treatment modalities and optimal care can be planned which minimize these complications. Anticipated dates to complete these activities are by June 2019.
3. Evaluation of service provision. Highlight any inequalities in access to specialist cancer care services, particularly in older teenagers and young adults, so that all patients have an equal chance of obtaining the best care irrespective of their personal circumstances and thereby having the best chance of cure. The work will be written up in the form of reports to commissioners and journal articles so that clinicians and commissioners can use this information in order to make any necessary changes to service delivery so that the entire Yorkshire and Humber cancer population is served equally well. Anticipated dates to complete these activities are by December 2018.
4. Financial planning. Information on hospital activity burden and NHS costs associated with the diagnosis and treatment of children and young adults with cancer will be calculated by the University research team in collaboration with health economists at the Leeds Institute of Health Sciences. Changes in costs over the last 20 years will be reported, adjusting for inflation, in order to provide cost projections over the next 10 years. This information will be collated in the form of a report to specialist commissioners of childhood and adolescent cancer services in the Yorkshire & Humber region so that, where required, service changes can be implemented in order to meet future NHS patient demand. Anticipated dates to complete these activities are by December 2019.
At the moment, these data are lacking and once identified by the YSRCCYP research team, they will provide important information:
* to clinicians to help better manage their clinic populations,
* to specialist commissioners to monitor the effectiveness of cancer care and
* to patients in order to understand more about their own risks of complications associated with the treatment they have received and wherever possible self-manage their own care and wellbeing.
* to identify gaps in access to specialist care by the research team for two distinct populations:
i) teenagers and young adults, who do not benefit from the same level of centralised care as that in place for younger children, and
ii) South Asians as they are more likely to present with cancer due to genetic risk factors. Improving care for teenagers and young adults and the south Asian population will ensure that their survival rates are optimal and equivalent to other age groups and ethnic groups, and any subsequent complications of treatment are minimized and if these do occur are then managed appropriately by specialist NHS professionals to ensure a full recovery.
Outputs, such as the risk stratification model, will be integrated into clinical practice through established links between the YSRCCYP research team and paediatric and adolescent oncologists throughout the Yorkshire region. The research programme as a whole benefits enormously from the long-running, close collaboration with haematologists and oncologists in the Yorkshire and the Humber region who all help to ensure that the University's research findings are effectively translated into clinical practice and are involved in all outputs from the YSRCCYP database.
Outputs:
Work describing risks of health effects of treatment in relation to respiratory illnesses will be completed by the YSRCCYP research team and submitted for publication in the British Journal of Cancer (or similar) by June 2018. The June 2018 publication follows a June 2016 publication where descriptive statistics have been produced showing the respiratory conditions diagnosed within the linked cohort. The background admission rates in the general population are required over the same time period to enable further statistical analysis to be carried out. Outcomes of the work will also be disseminated in open-access journals (e.g. BMC Cancer) and presented at conferences including the National Cancer Registration and Analysis Service Cancer Outcomes annual meeting, Teenage Cancer Trust and the International Society of Paediatric Oncology annual conferences. Further work will be submitted to the European Journal of Cancer (or similar) in relation to specific mental health outcomes by December 2018. Analyses describing the variation in clinical pathways including delays and time to diagnosis will be submitted for publication by June 2018 to Journal of Clinical Oncology (or similar).
Additional work describing the rates of hospital activity and differences between ages at diagnosis (e.g. 0-14 vs 15-29) and ethnic group (e.g. south Asian vs non-south Asian) will be completed by October 2017 and submitted for publication to the British Journal of Cancer by December 2017. Details of risk stratification models and the methodology to derive these for individual patients will be disseminated by the research team to every clinician involved in the care of children and young people (CYP) in December 2018. This will be supported by the Yorkshire & Humber CYP cancer network that holds details of all practicing NHS CYP cancer teams and clinicians in the region.
Summary reports of the work and research undertaken will be compiled and also made available on the Yorkshire Register University of Leeds website (http://medhealth.leeds.ac.uk/info/545/yorkshire_specialist_cancer_register), according to the timelines listed earlier in the document.
All outputs will be aggregated with small number suppression in line with the HES Analysis Guide.
As the funder, the Candlelighters Trust may request information for use in its own information dissemination and publicity materials. For example, they may ask for the number of new cases diagnosed per year in Yorkshire and projected incidence rates. The University of Leeds would only share information that is available as a result of the processing activities described above – i.e. the YSRCCYP would not undertake further data processing in order to derive information requested by the Candlelighters Trust and any information shared would be put in the public domain. For clarity, the University of Leeds is not obliged to provide information on request to the Candlelighters Trust and would not share any data that are not aggregated with small numbers suppressed in line with the HES Analysis Guide.
The linked NHS Digital data alongside the background hospitalisation rates will be used to derive key information which will be provided by the YSRCCYP research team to clinicians involved in the long-term care of young people identifying each individual’s risk stratification group (defined as being at ‘low’, ‘medium’, or ‘high’ risk of future complications or health effects, based upon their previous hospital activity patterns, treatment mortality, dose, cancer type and stage). The risk stratification model will be devised by the YSRCCYP research team and disseminated to clinicians in the Yorkshire and Humber region via the Y&H Children’s and Young People’s Cancer Network (December 2018). Only those clinicians involved in the direct care of individuals with cancer will be provided with details of the risk stratification model. Health care commissioners will be provided with aggregated cancer intelligence data on the number of survivors currently being seen at each NHS Trust according to risk stratification group, so future services can be planned effectively (June 2018).
Data will be held for as long as the research project is funded to undertake this piece of epidemiological and applied health research. Though work is currently planned until December 2019, the current funding expires on 31st August 2017. Subject to securing ongoing funding, the data would be retained until December 2019 to allow sufficient time for completion of analyses, submission and final publication of papers.
Processing:
The University of Leeds previously securely transferred files of identifiers for patients in the YSRCCYP (NHS Number, Date of birth, sex and postcode plus a unique study ID) to NHS Digital. NHS Digital returned linked HES and mental health data up to the period 2014/15 including the unique study ID and no other identifiers. This process will be repeated to obtain more recent HES and mental health data for the patients previously linked and to obtain HES and mental health data for patients added to the YSRCCYP since the previous linkage.
The University of Leeds stores the data on an encrypted secure area network (SEED) and access is restricted to individuals working on the YSRCCYP register research programme. Access to the record level data will only be by substantive employees of the University of Leeds and located within the Division of Epidemiology and Biostatistics. No NHS Digital data will be transferred outside of the University of Leeds or shared with any third party individual or organisation (apart from where stored at 2 disaster recovery sites at the University of York and Iron Mountain, where data will be stored only for the purpose of disaster recovery and not processed for any other purpose).
The cohort linked data (HES and mental health) and the pseudo-anonymised HES extract, provided under a separate Data Sharing Agreement (reference: NIC-155843-0MQMK), are stored in separate files and are distinct from the YSRCCYP data itself. The pseudo-anonymised HES extract will not be linked to the cohort data supplied by NHS Digital or in the YSRCCYP database. Different pseudonymised HES IDs will ensure this is not possible.
On receipt of cohort linked data (HES and mental health) the YSRCCYP research team undertake the following processing activities:
The data are initially checked for any errors or inconsistencies. This involves checking to ensure no duplicate episodes remain, which may have arisen either due to supplied duplicate HES episodes or the overlap between previously received HES data by the YSRCCYP research team, some of which may relate to provisional data releases. Further checks are made to ensure no multiple admissions existed which were less than 2 days apart with the same HES_ID, and no admission entries occurred after the date of death if deceased (the latter which is obtained from YSRCCYP database).
Length of hospital stay is calculated from the dates of admission and discharge and compared between cancer diagnostic groups, age groups, gender, ethnic group, socioeconomic status, level of specialist care, and distance from residential address to hospital (hence reasoning why the University needs OA code and grid reference).
Upon completion of checks, an extract of identifiable data (Date of Death and Date of Birth) is taken from the YSRCCYP database and linked to fields from the cohort linked HES data to calculate variables such as the duration from admission to death and age at admission where such variables are relevant to specific research questions.
The data will be compared with (but not linked with) data on inpatient hospital admissions for the general population in Yorkshire under the age of 60 derived from the pseudo-anonymised HES extract, provided under a separate Data Sharing Agreement (reference: NIC-155843-0MQMK). General population data will be compared with a population of the same age range in the cohort who were diagnosed with childhood or young adult cancer. The aim is to assess whether certain hospital admissions are more (or less) common amongst a population of survivors of childhood and young adult cancers following treatment compared to the general population. The risk of admissions of a certain diagnosis in the cancer population will be compared to that in the general population. The YSRCCYP research team aims to look at the whole admission pattern of patients, not simply those that occur in the primary diagnosis fields and therefore require an episode level extract as opposed to aggregated counts of admission.
Summaries of the results will be presented orally at conferences and are intended to be published in academic or medical journals. All outputs will be aggregated with small numbers suppressed and in line with the HES Analysis Guide.
Researchers who are not substantively employed by the University of Leeds may apply for access to data from the YSRCCYP but data supplied by NHS Digital will not be shared with any third parties.
Data will only be used for the purposes described in this statement. The NHS Digital data will not be linked to any other data apart from YSRCCYP data.
The YSRCCYP research team requires data from the full period from 1996/97 to 2016/17 (latest available) for several reasons. Firstly in order to address aim 1 investigating changes in levels of hospitalisation over time and within specific cancer types, age groups and sociodemographic groups. Secondly to maximise statistical power for analyses given the rarity of childhood and young adult cancer; also to assess changes in access over time to specialist cancer care services, as NHS policy regarding the recommendations for treatment of children and young people with cancer has changed with the opening of Principal Treatment Centres in hospitals across in England throughout this time frame.
Evaluating clinical care pathways and time to diagnosis also require data of all admissions prior to cancer diagnosis. The late health effects for childhood and young adult cancer survivors may occur any time after treatment ends and the risk of late effects increases as the cohort ages. In order to fully evaluate the total burden of adverse health events in these survivors’, data are required for as long a time period as possible. This may also include any hospital admissions prior to the patient’s cancer diagnosis to identify any underlying health conditions. The YSRCCYP research team is also notified about any subsequent malignant neoplasms from the National Cancer Registration and Analysis Service prospectively following the original cancer diagnosis and therefore need to retain all historical HES and mental health data in order to scrutinise any such individual’s history of hospital admissions and understand potential reasons for those who experience multiple tumour diagnoses.

Objectives:
The UK Women’s Cohort Study (UKWCS) was established to explore links between diet, lifestyle and chronic disease, in particular cancer. Previous cohort studies exploring diet and cancer have often produced results with small, not statistically significant effect sizes, due in part to the fact that diet is a complex exposure with measurement being subject to a variety of errors and bias. This measurement error has limited the ability to make dietary recommendations linked to chronic disease prevention, and many important questions remain unanswered. In addition, within population subgroups, diet often appears homogeneous, preventing any subtle effects of dietary differences from being detected. The UKWCS aimed to address these issues in a number of ways. Dietary information was obtained using two methods: a food frequency questionnaire (FFQ) and also a 4-day food diary to provide alternative measures of diet to allow for sensitivity analyses and potential minimisation of measurement error.
The UKWCS is a long standing cohort of 35000 women across the UK which is stored in the University of Leeds Integrated Research Campus (IRC). The cohort was established in 1995 and cancer incidence and death information was received on a quarterly basis for the participants. A list of publications resulting form the analysis is available on https://leedsbasic.wpengine.com/ukwcs/publications/
The University of Leeds are processing this data held under this agreement under their role as a University in the performance of a task in the public interest Article 6(2)(e) and Article 9(2)(j) with regards to the processing being necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law.
Most chronic diseases risk can be significantly reduced through changes in lifestyle factors, most markedly improvements in diet. Over recent years, many aspects of diet have been explored in relation to risk of chronic diseases. The Nutritional Epidemiology Group at the University of Leeds already have experience undertaking survival analysis (a statistical method for modelling disease risk) in the large cohort of British women and have previously published findings which show a reduced risk of breast cancer in pre menopausal women consuming a diet high in fibre and an increased risk of breast cancer in postmenopausal women consuming a diet high in meat and processed meat in particular. However, other chronic diseases such as CVD or specific receptor status of a cancer have not been recorded by Office of National Statistics (ONS).
The objective of this application is to create a new database by linking the existing UK Women's Cohort Study (UKWCS) with Hospital Episode Statistics (HES) data and to support analysis of a number of key research questions. The database will be made available to researchers working for the University of Leeds so that new links can be explored between diet/lifestyle and health outcomes. The additional HES data will create a unique research data set for the UK.
UKWCS will use historical HES outpatient and admitted patient care data in its studies to identify diagnosis after 1997 baseline information of dietary and lifestyle were gathered. Its important to determine any co-morbid conditions and identify the date when a patient first had a care visit for a particular diagnosis (index date).
In all cases, the purposes for which the research database can be accessed are restricted to those for the provision of health care or adult social care, or the promotion of health and must be in line with the purposes set out in this agreement relating to diet and lifestyle. The new data base will be used to undertake research into epidemiology of diseases to improve patient care and health economic and geographical studies. These studies support the long term sustainability of the NHS by evaluating cost effectiveness of healthy diet and lifestyle.
Researchers from University of Leeds conducting studies using the new data base need to establish the index date of a patient at the beginning of treatment or diagnosis in order to determine primary diagnosis over a follow up period. Researchers also need to understand if patients have a history of serious co-morbid conditions e.g. if a patient was hospitalised 10 years ago for a stroke then this needs to be taken into account. By answering these questions researchers are able to build cohorts for studies with the right type of characteristics. If historical HES data was not provided then researchers could miss important events which would then not be adjusted for in study results.
Accessing the data involves an application process for bona fide researchers with an established scientific record. This approach ensures the reputations of the UKWCS team and its participants are not compromised through unethical, premature or opportunistic data analysis.
The UKWCS follow the MRC definition of bona fide research:
http://www.mrc.ac.uk/publications/browse/mrc-policy- and-guidance-on-sharing-of-research-data-from-population and-patient-studies/(page 24) - see below section 5b, for details of that process. This data will be pseudonymously linked by NHS Digital.
Researchers will only be given access to the minimum amount of data from the database required for them to carry out their analysis.
The Consumer Data Research Centre (CDRC) and Integrated Research Campus (IRC).
The Consumer Data Research Centre (CDRC/Centre) was established in 2014 by the UK Economic and Social Research Council as part of the phase two Big Data Network. Led by the University of Leeds and University College London, with collaborators at the Universities of Liverpool and Oxford, the CDRC’s key objectives have been to provide stakeholder access to consumer data via a national data service and to deliver an innovative programme of research and training in consumer data analytics. Over the past five years the Centre has achieved considerable success in both acquiring and sharing novel data sets. The University of Leeds has entered into data sharing agreements with data owners on behalf of the Centre, as the CDRC is a non-legal entity. The data disseminated under this agreement will remain under the data controllership of the University of Leeds. Collaborators in the CDRC: University College London the Universities of Liverpool and Oxford do not have any remit of role around the use and access of the NHS Digital disseminated data.
At Leeds, the CDRC forms part of the Leeds Institute for Data Analytics (LIDA); a purpose built facility that brings together applied research groups and data scientists from across a wide range of disciplines. LIDA is underpinned by the Integrated Research Campus (IRC), an advanced computational infrastructure that is highly secure and scaleable to meet the needs of data-intensive research. The IRC platform provides a secure Virtual Research Environment (VRE) for each research project. Access to the CDRC’s most sensitive data is facilitated via the IRC and supported by LIDA’s data services team. All staff working at the LIDA are substantive employees of the University of Leeds.
Following a process of external independent assessment, the IRC has attained accredited certification to the international standard for information security management, ISO/IEC 27001:2013. Alongside its work to align to the ISO standard, the IRC has worked towards compliance with information governance requirements set by NHS Digital and the Department of Health. The IRC’s information security management system has been reviewed up to the minimum ‘level 2’ and is deemed satisfactory. This means that the IRC meets the requirements to store health data shared by NHS Digital, Public Health England and other NHS or social care organisations.
The Senior Management Team (SMT) within Leeds University will assess whether the data access requested by the researchers fits the Centre’s (CDRC) remit. The UKWCS team is notified that an application for the linked UKWCS data has been received. Every application will be examined by the CDRC Research Approval Group (RAG). A policy agreement document is in place to explain the application process for researchers interested in analysing existing data and the terms and conditions that must be agreed before data can be used.
A member of the CDRC Research Approval Group (RAG) will then be selected as the Contact Researcher for each project. If possible, s/he will be the preferred Contact Researcher named on the application form. The Contact Researcher will inform the applicant of the decision in writing. Approval from the committee is “in principle”, subject to the applicant signing and returning the UKWCS Data User’s Agreement Form. The Contact Researcher will be the point of contact for the duration of the project. New project analysis will require a new application being submitted and approval by the CDRC Research Approval Group (RAG). New pseudonymised datasets will be created for each agreed project where the data will be minimised to fit each specific project and the data will be made available within the CDRC where the researcher can have access. The researcher data can be accessed until their specific project end date.
Specific purposes of use for the new database:
Listed below are the relevant exposures and outcomes for which the UKWCS database can be used to explore links between Diet, lifestyle, and chronic disease in line with the CAG approvals to do this below are the areas which will be investigated,
1 Food, nutrient intakes and dietary patterns – identified from both the food frequency questionnaire and food diary data. Chronic diseases prevalent in older people, such as risk of malignant neoplasms, heart disease, other chronic diseases such as diabetes, Alzheimer’s Disease, hip fracture, kidney failure.
2 Measures of physical activity and sedentary behaviour Chronic diseases prevalent in older people, such as risk of malignant neoplasms, heart disease, other chronic diseases such as diabetes, Alzheimer’s Disease, hip fracture, kidney failure.
3 Body mass index and other anthropometric measures available (height, weight, weight change, waist-hip measures, clothes size). Chronic diseases prevalent in older people, such as risk of malignant neoplasms, heart disease, other chronic diseases such as diabetes, Alzheimer’s Disease, hip fracture, kidney failure.
4 Other lifestyle behaviours available in the cohort such as smoking, alcohol intake, taking dietary supplements, breast feeding. Chronic diseases prevalent in older people, such as risk of malignant neoplasms, heart disease, other chronic diseases such as diabetes, Alzheimer’s Disease, hip fracture, kidney failure.
5 Social aspects of participants: education level, social class, marital status, employment status, children in household. Chronic diseases prevalent in older people, such as risk of malignant neoplasms, heart disease, other chronic diseases such as diabetes, Alzheimer’s Disease, hip fracture, kidney failure.
6 Health experience of participants and family members – self-reported eg. previous high blood pressure, high blood cholesterol and treatments for long-term conditions (self-reported) including anti-inflammatory use. Chronic diseases prevalent in older people, such as risk of malignant neoplasms, heart disease, other chronic diseases such as diabetes, Alzheimer’s Disease, hip fracture, kidney failure.
7 Obstetric history of participant, child birthweight, and other lifecourse markers. Chronic diseases prevalent in older people, such as risk of malignant neoplasms, heart disease, other chronic diseases such as diabetes, Alzheimer’s Disease, hip fracture, kidney failure.
Specific examples of each area of research include (these are not intended to be exclusive but to illustrate planned and potential work relating lifestyle data held in the UKWCS to disease outcomes provided by HES):
1. Food intake and dietary patterns on incidence of Alzheimer’s Disease or dementia.
UKWCS will use HES data to examine which dietary factors influence incidence of Alzheimer’s Disease (AD) or dementia. HES records will be used to identify cases of AD or dementia. Specific dietary factors will be the focus: high fat/meat intakes or Mediterranean/vegetarian dietary pattern.
2. Physical activity and risk of all causes of cancer.
Physical activity and sedentary behaviour will be explored in relation to risk of cancer incidence. HES data will be used to provide information on cancer incidence. The study will explore how frequency, amount and intensity of physical activity is associated with future risk of cancer. Sedentary behaviour will also be taken into account.
3. Body mass index, clothes size and risk of colorectal cancer.
The relationship between body mass index (BMI), lifetime change in BMI, and clothes size in relation to risk of colorectal cancer will be explored. HES data will provide the colorectal cancer incidence information. This analysis will help Leeds University to understand the role of weight over the lifecourse in relation to risk of colon and rectal cancer.
4. Breast feeding in relation to risk of breast cancer and other female reproductive cancers.
Breast feeding duration and frequency will be explored as a protective factor for breast cancer incidence. Analysis will make use of PHE hormone receptor status data and HES data for breast cancer risk.
5. Influence of diet on social class and risk of CVD.
Investigators: to be identified and including UKWCS team.
Dietary behaviours are associated with social class. The impact of diet in relation to different social groups on risk of heart disease will be explored. Careful consideration of confounding factors will be required and analysis will be stratified according to social group. HES data will provide information on diagnosis of coronary heart disease, myocardial infarction and stroke.
6. Diet as a mediating factor between high blood pressure and risk of kidney disease.
Essential hypertension is associated with high intakes of salt. Other components of diet will also be explored in relation to risk of essential hypertension. How these factors then link with risk of developing kidney disease will be explored. HES data will provide kidney disease diagnoses.
7. Influence of parity and lactation on hip fracture risk.
Several studies indicate that parity and lactation are associated with modest, short-term bone loss, but the long-term effect on osteoporotic fracture risk is uncertain. The UKWCS has information on parity, lactation and use of oral contraceptives. HES data will provide hip fracture incidence data.

Expected Benefits:
The researchers at university of Leeds will be using the linked data to produce (on an ongoing basis) research publications in peer-reviewed journals and presentations in scientific conferences. The data will be used to undertake independent research into disease management and outcomes to improve patient care, health economic studies and epidemiology of diseases with regards to dietary and lifestyle exposure.
The previous UKWCS database is extensively used by researchers to undertake population-based health research studies. There have been nearly 100 peer reviewed publications utilising the UKWCS database since its establishment in 1995. Findings are also shared through extensive public engagement activities including regular Scientific events and lectures to general public and health groups.
The UKWCS is one of the longest running of the British women's cohort studies. Today, the UKWCS offers a unique opportunity to explore the long-term biological and social processes of ageing and cause of death. Evidence is growing from this cohort study and others, that factors from later life (such as adult smoking, diet, exercise and socioeconomic circumstances) affect the opportunity to age well. This is of interest to policymakers, practitioners, and older people themselves. As the study is nationally representative, it will also provide valuable information regarding the factors associated with health care utilisation of the middle-age of women population.
The linked data set will be used to undertake independent research into disease management and outcomes to improve patient care, health economic studies, nutrition and health epidemiology studies. It anticipates adding to the knowledge to improvements in preventing chronic disease and maintaining good health in middle-aged women. Prevention depends on understanding of causes. The UKWCS can help provide a better understanding of mechanisms underlying disease and health; how these are influenced by the environment and what the potential population impact might be. There is increasing evidence for common pathophysiological pathways including glucose metabolism, inflammation, and hormonal profile for ageing related conditions. In addition to chronic disease and cancers, there need to be a better understanding of outcomes relevant to older populations such as functional health and quality of life. The UKWCS is a large long term prospective study that allows this approach. In particular, through knowledge transfer, public engagement, publications, presentations and invited commentaries (https://ukwcs.leeds.ac.uk/) the UKWCS has contributed to a body of evidence to influence policies and support evidence based medicine.
The example projects provided above have anticipated benefits including:
Project 1: Food intake and dietary patterns on incidence of Alzheimer’s Disease or dementia.
This research will lead to a better understanding of the risks associated with different dietary behaviours and future risk of dementia and Alzheimer’s Disease. It therefore has the potential to impact on public health policy.
Project 2. Physical activity and risk of all causes of cancer.
Physical activity is associated with risk of cancer, however, the interplay between diet and physical activity in relation to BMI and other cancer risks is unclear. The UKWCS has previously shown that fidgeting in sedentary women is protective against all cause mortality. This new analysis will lead to a better understanding of physical activity and sedentary behaviour in relation to cancer risk. It therefore has the potential to have an impact on public health policy.
Project 3. Body mass index, clothes size and risk of colorectal cancer.
Whilst it is known that some cancers are associated with BMI, it is not clear how change in BMI over the life course is associated with risk of colorectal cancer. The UKWCS has previously shown that skirt and blouse size is associated with risk of breast cancer. The study now wishes to repeat this work exploring risk of colorectal cancer. Findings for this study could help to provide a simple contributor to a risk score when measured height and weight to calculate BMI is not available since individuals do know what size clothes they buy.
Project 4. Breast feeding in relation to risk of breast cancer and other female reproductive cancers.
Whilst it is known that breast feeding has many benefits for both mother and child, the relationship of lactation on later risk of breast or other female reproductive hormone cancers is unknown. This work has potential to influence public health policy promoting breast feeding.
Project 5. Influence of diet on social class and risk of CVD.
Middle-class people generally have healthier diets than lower-class people. Dietary mediators seem to play an important role in the pathogenesis of cardiovascular disease, mediating some of the discrepancies in atherosclerosis among different socioeconomic layers. Further understanding of these relationships will help to drive public policy and strategies for reducing inequalities across the social classes.
Project 6. Diet as a mediating factor between high blood pressure and risk of kidney disease.
High blood pressure (HBP or hypertension) is the second leading cause of kidney failure. Over time, uncontrolled high blood pressure can cause arteries around the kidneys to narrow, weaken or harden. Some dietary behaviours may increase blood pressure (eg. high salt) whereas other dietary patterns (eg. DASH diet) may support blood pressure reduction. Understanding of how diet may influence blood pressure and kidney disease will provide more evidence to help develop prevention and treatment strategies with clear public benefit.
Project 7. Influence of parity and lactation on hip fracture risk.
Several studies indicate that parity and lactation are associated with modest, short-term bone loss, but the long-term effect on osteoporotic fracture risk is uncertain. The UKWCS can provide further evidence to the limited data available on this topic worldwide. Any associated effect with oral contraceptive use could influence policy around prescribing
Outputs:
The researchers who use these data will be producing (on an ongoing basis) research publications in peer-reviewed journals structured along the lines of a scientific paper (e.g. Summary, Background, Methods, Results and Discussion) eg. BMJ, Lancet, Nature, British journal of Nutrition, and Public Health Nutrition Journal. Interim tables of results (aggregated data with small number suppression in line with the HES analysis guide) may be circulated as interim results for discussion and appended to the study report at the end of the project. Further outputs include presentations in scientific conferences; such as Nutrition Society Summer Conference, Society for Social Medicine, etc. Leeds University appreciate the time taken for publications to appear and so anticipate the timing for this activity within one or two years after the data has been analysed.
After receiving the data linkage, UKWCS team will focus on optimising the database within 1 month after receiving the data and the database will be available for researchers to access by then.
Researches at the University of Leeds can access pseudonymised, non-sensitive record level database or delivery of aggregated tables; presentations, spreadsheets, word documents and other formal documentation for generation of research publications in peer-reviewed journals; and conference posters or presentations in scientific conferences. Information to be included in health assessments, nutrition and lifestyle epidemiology, natural history of disease, health economics and outcomes research.
All outputs will contain only data that is aggregated with small numbers suppressed in line with the HES Analysis Guide
Processing:
The UK Women's Cohort Study (UKWCS) data provides information on diet, health and lifestyle. This database is stored electronically by the University of Leeds in restricted access files. The new research database proposed (UKWCS-HES) will have the current UKWCS data linked with information from Hospital Episode Statistics (HES) and the Office of Data Release (ODR) from Public Health England.
A long period of data is required as the study is monitoring impact of wider health conditions that may take many years to manifest. The major health conditions are likely to become visible at least 10 years after the certain dietary and lifestyle is practised. The analysis needs to take account of morbidities prior to the start of the study. Individuals who had prior morbidities [e.g. heart defect, cancer, etc.] may be more/less likely to exhibit certain behaviours/contract certain health conditions of relevance to the study.
Due to the potentially wide variety of possible harms which might be attributed to the varied health outcomes in the UK women, the study requires wide ranging hospital episode data not restricted to specific types of episode. The date of birth/incidence/death will generally be used in the analysis to derive age at episodes.
DATA FLOW
The process for data merging and dissemination will have 2 steps.
• Step 1: Create new merged database in secure Virtual Research Environment (VRE) then strip identifiable variables to create a pseudonymised data set.
• Step 2: Pseudonymised data set made available to other researchers in safeguarded area of Consumer Data Research Centre (CDRC).
STEP 1 Create new merged database and pseudonymous data subset
An encrypted participant list which holds ID number, date of birth and NHS number will be created and securely transferred to NHS Digital so cohort participants' records can be extracted. The University of Leeds Integrated Research Campus (IRC) will receive and store data through a secure file transfer of data from the UKWCS database linked with data from both Hospital Episode Statistics (HES) and Civil registration data from NHS Digital and the National Cancer Registration and Analysis Services (NCRAS) from Public Health England. This linked data will form the basis of the new research database (UKWCS-HES).
The location of access is restricted. The IRC Data Services Team carry out disclosure control checks using relevant guidelines on anonymisation, data publication and any legislation or agreements that apply specifically to the project or the dataset. This ensures that no inappropriate data is removed from the Virtual Research Environment (VRE). All direct identifiers will be removed, apart from ID number prior to use by researchers.
All outputs are independently reviewed by the IRC Data Services Team prior to leaving the IRC. This means that the pseudonymised database will be reviewed using the IRC disclosure control process. This is set out by the IRC Data Transfer Policy. This process ensures that anonymity of patients, care providers and any third party is maintained. The staff undertaking disclosure control checking have received training in disclosure control and output checking from the UK Data Services and outputs are reviewed in line with the NHS Digital Disclosure Control Guidance e.g HES analysis guide and any other legislation or agreements that apply to the particular project or dataset.
Once step 1 is complete, the pseudonymised database will be deposited in the Consumer Data Research Centre (CDRC) to facilitate research requests and analysis.
Step 2 - Requests received for access to pseudonymous data set which are when approved made available to the researcher. the researcher will be either a substantive employee of University of Leeds or will have an honorary contract with University of Leeds.
The Senior Management Team (SMT) will assess whether the data access request fits the Centre’s remit. UKWCS team is notified that an application for their data has been received.
If acceptable the application will then be examined by the CDRC Research Approval Group (RAG).
The RAG consists of the chair member, ESRC and CDRC representatives, plus a member of the UKWCS team . A member of the CDRC RAG will then be selected as the Contact Researcher for each project and named on the application feedback letter.
The Contact Researcher will inform the applicant of the decision in writing. Approval from the committee is “in principle”, subject to the applicant signing and returning the CDRC User’s Agreement Form. The Contact Researcher will be the point of contact for the duration of the project. Further use of the data outside those specifically stated in the application form for other areas of interest will require a new application being submitted and approval by the CDRC Research Approval Group (RAG). The researcher will be required to list the variables they are interested in. The RAG will ensure the data requested is adequate, relevant and limited to what is necessary in relation to the purposes for which they have been requested in line with GDPR necessity tests.
RAG would assess whether the request fits with the purposes set out in this agreement. Leeds University ensure that the data accessed by each project outlined in the application has met the necessity test with regards to GDPR requirements.
University of Leeds staff, students and visitors would be able to apply for the data for research. If a researcher is not already a substantive employee of the University of Leeds then an honorary contract with visiting status would be set up containing the following text:
The University of Leeds will inform [your substantive employer] of any incident related to unauthorised disclosure or breach of confidence. [The substantive employer] retains responsibility for your conduct in connection with your work, including in particular your compliance with the terms of the honorary contract, as if your work or activities were performed for [the substantive employer]. Accordingly, [the substantive employer] agrees to take all appropriate disciplinary action promptly if any condition within this Agreement is breached by you.
(The agreement will be signed by the individual, the substantive employer, and the University of Leeds. This will ensure that the individual will be subject to the disciplinary process of their substantive organisation if he/she does something amiss with the data .) For all honorary contracts that the University of Leeds remains the Data Controller.
Any data processing within the study purpose by the applicant will use the pseudonymised database deposited in the Consumer Data Research Centre (CDRC) by the IRC Data Services Team. This will be through the use of a unique identifier assigned to each patient in the database instead of personal details such as name or NHS number; in line with the section 251 approval (without consent) through the Confidentiality Advisory Group (CAG) of the Health Research Authority.
Data may be linked to other publicly available data which would not increase the risk of re identification. Leeds university has appropriate operational arrangements for making sure linkage to the public available data will not increase the risk of re-identification. Risk assessments are conducted to identify risks to information assets in the IRC and classify these by probability and likely impact of occurrence. A risk assessment defines any risk mitigating actions that can be taken to prevent the occurrence or reduce the impact of risk. A treatment plan is then designed in order to manage and contain risk, or a risk owner is assigned, to complete the risk assessment.
All organisations party to this agreement must comply with the Data Sharing Framework Contract requirements, including those regarding the use (and purposes of that use) by “Personnel” (as defined within the Data Sharing Framework Contract ie: employees, agents and contractors of the Data Recipient who may have access to that data).

Objectives:
The UK GRACE Risk Score Intervention Study (UKGRIS) aims to find out whether there is a difference in a patient’s health following an unstable angina attack or a heart attack if treated according to a hospital’s usual care or if treated using the GRACE risk score tool.
The UKGRIS study will randomly assign recruiting hospitals to either continue with their current usual care or use of the GRACE risk score tool for the care of their patients admitted with a suspected NSTEACS (type of unstable angina attack or heart attack). Sites are only recruited into the study if their current usual care is not the use of the GRACE risk score tool.
When a patient has had an NSTEACS, the NHS has care processes (such as medication, further tests or health guidance) which are recommended for the patient based on how severe their NSTEACS is. These are called Class 1 guideline recommended care-processes. To decide whether there is a difference in patient’s health the study will compare each arm of the study (usual care vs GRACE risk score) by looking at how many of these Class 1 guideline care-processes a participant receives.
The study will also look at whether the participant goes on to experience any cardiovascular related events such as cardiac death, heart failure, new onset myocardial infarction, cardiovascular hospitalisation following on from their NSTEACS to see whether there is a difference between the two arms of the study. To look at these cardiovascular related events the study requires hospital episodes and mortality data.
The GRACE Score is a prospectively studied scoring system to risk stratify patients with diagnosed Acute Coronary Syndrome (ACS) to estimate their in-hospital and 6-month to 3-year mortality.
The co-primary objective for the UKGRIS cluster-randomised trial, which plans to recruit 3000 patients from a minimum of 30 hospitals, is to assess whether the application of the GRACE risk score on patients with urgent acute coronary syndromes without ST-segment elevation (NSTEACS) admissions results in better uptake of Class I guideline recommended care-processes, and reduces the incidence of a composite cardiovascular endpoint (cardiac death, heart failure, new onset myocardial infarction, cardiovascular hospitalisation). Secondary objectives are to assess the difference in terms of:
1. unscheduled revascularisations within 12 months
2. duration of hospitalisation within 12 months;
3. patient-reported quality of life at 12 months;
4. the four individual components of the co-primary composite endpoint of cardiovascular events.
This agreement relates to the second co-primary endpoint, and on secondary endpoints 1, 2 and 4. The data required to derive these endpoints are to be obtained through routine electronic health records.
The UKGRIS study was funded by the British Heart Foundation in June 2016 and is currently recruiting patients, having opened in March 2017. The University of Leeds Clinical Trials Research Unit, a UKCRC-registered trials unit, manages the trial and comprises a multidisciplinary team of data managers, trial managers, information systems support and statisticians. All of this data is pseudonymised.
Data from NHS Digital are critical to tracking the clinical follow-up of the patients who consented to take part. Other than a mailed postal questionnaire at 12 months to assess quality of life, The University of Leeds are not performing a clinical follow-up for hospital staff to review medical records to identify relevant clinical events, admissions and / or death information hence the University of Leeds are unable to perform the planned analyses of the UKGRIS trial without the timely delivery of the required NHS Digital data.
The UKGRIS study, as a stand-alone project is wholly confined within the United Kingdom. This research dataset will comprise self-reported questionnaire data, case report forms collected during the trial, and data from other national data cokllections, including HES data and mortality data. This data will be processed to create a research psuedonymised dataset without identifiers, such as date of birth, dates of events/episodes, and including derived variables such as age at registration, numbers of days since registration event/episode.
The protocol has been harmonised with a similar study in Australia (AGRIS* ) with the intention that the two trials (plus an additional planned Canadian study) will combine these derived, de-identified datasets to perform an international collaborative individual participant data (IPD) meta-analysis. Doing so will allow the estimation of smaller differences in cardiovascular events observed during follow-up. Derived data will only be shared with the international collaborators upon agreement with NHS digital that the data is sufficiently derived to satisfy the requirements of NHS digital. The Leeds Institute of Clinical Trials will work with NHS digital to reach agreement on the data to ensure that NHS digital agree that the data is derived sufficiently prior to being shared. A special condition which prevents any onward data sharing has been added to this agreement.
Whilst the main analysis for this study will commence once full patient recruitment has completed at the end of 2019 early 2020 data is being requested now from NHS Digital to allow the study to explore the methodology.
Expected Benefits:
Acute coronary syndrome (ACS) which includes ST-elevation myocardial infarction (STEMI), non ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) comprises the leading cause of emergency hospitalisation in Europe, a leading cause of death and disability and have major impacts on health economies. NSTEACS represent over half of the cases of ACS of which NSTEMI account for around 50,000 National Health Service hospitalisations per year. Evidence from randomised controlled trials (RCTs) as well as guideline recommendations from the European Society of Cardiology (ESC) and the National Institute for Health and Care Excellence (NICE) support the use of different strategies according to risk status because allocation of a treatment strategy significantly reduces subsequent cardiovascular events. In place of generic treatment of all patients, stratified care has the potential to achieve cost-effective patient-centred treatment as well as improved outcomes.
The state of clinical practice for the management of patients with ACS falls short of the state-of-the-art based on evidence and guidelines, which recommend risk-stratified patient management. Earlier work has shown that there is considerable diversity of clinical practice across centres and countries. The University of Leeds work also reveals that, for patients eligible for care, those who had fewer missed treatment opportunities had improved survival and that this varies geographically within England. Additionally, evidence from the UK (Myocardial Ischemia National Audit Project) MINAP registry has shown that more comprehensive treatment was associated with improved outcome.
Moreover, early ‘failure’ of receipt of an evidence-based care opportunity was significantly associated with subsequent missed guideline recommended treatments. In the UK the adoption of ACS therapies, including the diffusion of primary PCI, lags behind other countries. Between 2004 and 2010 this was associated with over 11,000 avoidable deaths. It is probable, therefore, that earlier and more widespread adherence to evidence-based ACS therapies at initial presentation will result in better outcomes. What is more, the failure to apply major guideline evidence-based treatments, in those without contraindications not only increases preventable deaths from cardiovascular disease, but diminishes the cost effectiveness of therapies.
In light of the unmet need described above, it is expected the following benefits will result from the reported outputs of UKGRIS based on the use of the requested data:
1) A measure of the difference in uptake of each guideline, indicating the difference in immediate resource utilisation due to use of the GRACE risk score requiring medication prescription and / or diagnostic testing;
2) A measure of the difference in cardiovascular events, hospitalisations and unscheduled revascularisations, resulting from data requested in this application, may persuade a decision maker to adopt the GRACE risk score in routine practice for these patients to improve their outcomes, reduce patient burden due to downstream events, as well as reducing medium term resource utilisation.

Outputs:
A download of data will be required upon approval so that the University of Leeds can present the data at the Trial Steering committee meeting
The British Heart Foundation has funded this study on the basis that The University of Leeds will be obtaining follow up data on the participants to answer the primary and secondary objectives. The University of Leeds provide them with 6 monthly updates on their progress.
The current timelines anticipate an end to recruitment by December 2019, with the final 12 months’ follow-up concluded by December 2020, after which analysis will begin to be complete by June 2021. Prior to that, the independent Data Monitoring Committee has requested an interim review of safety data available on the patients recruited so far, though no binding stopping rules will be in place.
A “Stopping rule” is a criterion (or set of criteria) that, if met, would indicate that the trial should be terminated early (that is, before the scheduled end of recruitment). Typical reasons for terminating early are futility (the final trial results are unlikely to show benefit to the intervention), harm (the intervention is leading to more adverse events, or fewer beneficial outcomes than the standard care arm) or efficacy (at this stage, the intervention benefit is such, that the study is already highly likely to have rejected its null hypothesis). In all of these cases, early termination avoids wasting the time of patients that have yet to be recruited (and avoids exposing them to unnecessary harm / lack of benefit shown in the data so far).
Stopping rules may be “Binding” or “Non-binding”/”Advisory”. Binding stopping rules are mandatory: if the criteria are met, the trial must be terminated early. Advisory stopping rules may be overruled by the DMEC if, on the balance of all the data available, there is still merit in continuing the study.
The study does not have any predetermined rules (Binding or otherwise) where the study would be stopped if the data showed a safety issue in either arm of the study. The data will be reviewed by the Data Monitoring and Ethics Committee and if they consider that it is not safe to continue with the study then it will be based on their medical and scientific expertise rather than any predefined stopping rule.
The Data Monitoring and Ethics Committee (DMEC) provide independent trial oversight and comprise independent members (that is members who are not co-applicants, not involved in trial conduct at the site level and not employees of the sponsoring or funding organisations and not from other participating organisations) with expertise relevant to the conduct of the study. The DMEC will review the safety and ethics of the trial by reviewing interim data during recruitment and will recommend on the continuation of the trial, or if any changes to the study design are indicated. Recommendations from the DMEC are made to the Trial Steering Committee, who make the final recommendation to the sponsor and funder that the study should be terminated early, if necessary. They will be provided with the following anonymised data, which is held in house at CTRU – having collected these on the case report forms - and are not requesting from NHS Digital;
• Aggregate recruitment by centre
• Aggregate screening data by centre by reason
• Aggregated numbers of deaths occurring before discharge and withdrawals
• Aggregated summary data on Protocol adherence
• Aggregate participant baseline characteristics (obtained from hospital completed data)
From the NHS Digital data download that is the subject of this application, It is expected to provide the following information to enable a single informal interim assessment (prior to completion of recruitment) of the safety profile of the GRACE and the Standard Care arms:
• Aggregate Numbers of post-discharge deaths (all-causes) in GRACE arm and the same in Standard care arm
• Aggregate Numbers of deaths (cardiac causes, pre and post discharge), in the GRACE arm and in the Standard care arm
• Aggregate Numbers of participants (and numbers of events) experiencing one or more of the component events of our composite clinical endpoint: Non-fatal myocardial infarction, New onset heart failure (admission), Cardiovascular readmission's (as well as cardiac cause of death), all for the GRACE arm, and separately for the standard care arm.
Details of the full set of data items to be downloaded for the final analysis is given in the original application.
After final analysis (expected completion June 2021) The University of Leeds plan a single publication comprising all outcome data on guideline uptake, cardiovascular outcomes, quality of life, revascularisations and hospital stay duration. The University of Leeds believe that the clinical question is of sufficient strength to submit in the first instance to a high-impact peer-reviewed general medical journal (eg New England Journal of Medicine, The Lancet, Journal of the American Medical Association, Annals of Internal Medicine, BMJ). The University of Leeds believe that these outputs would be of interest to a general medical community, hence their initial submission strategy. Should The University of Leeds be unsuccessful with such journals, they will prioritise publication in high-impact cardiology-specific journals, (eg Journal of the American College of Cardiology, Circulation). Ahead of publication, The University of Leeds would also seek to present their findings at a leading peer-reviewed international cardiology congress (eg European Society of Cardiology). In order to allow access to these outputs, The University of Leeds would either ensure that the outputs were open access, or that author manuscripts were available in depositories for access. (The British Heart Foundation mandates open access as a condition of funding).
The trial has a separate methodological sub study relating to rates of return of postal questionnaires, which may warrant a separate publication. (or inclusion in the main trial output) As this does not require the use of electronic health records, this is not relevant to the present application, and so The University of Leeds do not give further details here.
After final analysis the British Heart Foundation have agreed to an article on their website regarding the outcomes of the study.
The CTRU website will also be updated with information regarding the outcome of the study so this can be disseminated to the general public.
All outputs will contain only data that is aggregated with small numbers suppressed in line with the HES Analysis Guide.
Processing:
The University of Leeds will receive data for an identified cohort for the UKGRIS trial, for whom the University of Leeds provide identifiers already collected from participants as part of the trial dataset. These are: name, address, NHS number and date of birth. This ensures the University of Leeds minimise the chance of receiving data for anyone other than consenting trial participants. Identifiers will be sent from the University of Leeds to NHS Digital in an excel spreadsheet via a secure file transfer service. (Details for which can be found in the help documentation on the service homepage at https://lictr.leeds.ac.uk/sft)
The University of Leeds receive identifiers from the cohort, which are submitted to NHS Digital and NHS Digital return the HES and Mortality data with a study id for linkage and no direct patient identifiers.
Initially, data is requested from the time of the first recruitment to the first download (being greater than 12 months after the first participant has been recruited) and this is a safety measure to monitor any difference in events between each arm and will be presented to The University of Leeds Data Monitoring Committee. National data is required to ensure that The University of Leeds have sufficient numbers to identify any safety issues in an arm.
Patients have given written informed consent to participate in the trial and to use their identifiers at the University of Leeds which are collected as part of the trial - data provided by participants and researchers in accordance with the REC-approved trial protocol and participant consent.
The University of Leeds have minimised the number of identifiers and sensitive data items to those that are needed to be able to correctly track participants and ensure that the University of Leeds can answer the study objectives.
Data will be entered into a secure password protected database held locally at the University of Leeds via an automated data import service. Either the Trial Manager or Trial Statistician will access the data to ensure it has been successfully uploaded into the database, this will be the requested NHS Digital HES and Mortality data set. The data will then be processed by the trial statisticians at the Clinical Trials Research Unit, Leeds Institute for Clinical Trials Research (LICTR) at the University of Leeds. All individuals with access to the data are substantive employees of the University of Leeds, data will only be accessed by individuals within the CTRU who are directly involved with the NHS Digital transfer and analysis of the data (Trial statisticians and Trial Manager).
Data will be linked with existing UKGRIS Trial datasets (consisting of patient demographics and clinical characteristics at registration, details of in-hospital management, and results from diagnostic tests (if done) as well as quality of life questionnaire at baseline and 12 months’ follow-up) and The Myocardial Ischaemia National Audit Project (MINAP) and British Cardiovascular Intervention Study (BCIS). The data will be used to determine secondary endpoints relating to safety in terms of cardiac cause of death, new onset MI, heart failure, cardiac hospitalisation, length of hospital stay and unscheduled revascularisations.
The only data linkage that will occur is with the above-named cardiac registry data sets (for which permissions for the data will be sought from the responsible parties). No “trend analysis” will be performed. However, as the Hawthorne Effect (the recruiting hospitals improve performance due to being observed in a trial) is a potential concern, the study may use the above-named data-sets to compare UKGRIS and non-UKGRIS patients in terms of MINAP data on patient management. Any non-UKGRIS patient data accessed for this purpose will be anonymised / aggregated with small number suppressed to minimise the risk of disclosure. There will be no data linkage undertaken with NHS Digital data provided under this agreement that is not already noted in the agreement.
Data will not be used for any other purposes: it will not be used for commercial purposes, nor for direct marketing purposes.
All organisations party to this agreement must comply with the Data Sharing Framework Contract requirements, including those regarding the use (and purposes of that use) by “Personnel” (as defined within the Data Sharing Framework Contract ie: employees, agents and contractors of the Data Recipient who may have access to that data).

Objectives:
Bradford Teaching Hospitals NHS Foundation Trust and the University of Leeds are requesting to use NHS Digital data for a study entitled "Improving the Safety and Continuity Of Medicines management at Transitions of care" (ISCOMAT).
ISCOMAT has received a favourable ethical opinion, is funded by the National Institute for Health Research (NIHR) and is performed by a public authority. Bradford Teaching Hospitals NHS Foundation Trust's and the University of Leeds' lawful bases for processing personal data and health data (defined as special category data) for the purposes of this project are:
Article 6:1(e): Specific task in the ‘public interest’ or task that has a clear basis in law, and
Article 9:2(j): Special category data used for “Archiving in the public interest, scientific or historical research or statistical purposes”, with a basis in law.
Participants consented to have their personal data shared with NHS Digital, including personal details (initials, date of birth, postcode and NHS number) to be shared with NHS Digital for this project. Participants who withdrew their consent for data collection from routine sources will not form part of this cohort for this data application. All consent documentation and subsequent amendments to it were reviewed and approved by the ISCOMAT Patient Led Steering Group.
ISCOMAT Background and rationale:
Making the use of medicines as safe and effective as possible are priorities for patients and healthcare providers. When a patient moves, for example from hospital to home, medicine problems are common and planned changes are not always followed through. Patients particularly at risk are those with long-term illnesses taking several medicines – especially when medicines have been started or changed in hospital.
Heart failure can be managed through a combination of several different drug combinations at titrated doses. Successful management of heart failure patients’ medication can reduce hospitalisations, improve quality of life and increase survival rate. Optimising the management of medication as patients transition from hospital to home is complex, and requires co-ordinated input from different healthcare organisations, including hospitals, pharmacies and general practice, and different healthcare professions.
Heart failure affects 26 million people globally, approximately 900,000 people in the UK and the incidence of new diagnoses of the condition is increasing, affecting older people and those from lower socio-economic groups in greater numbers.
Aim:
ISCOMAT is a programme of interlinked work packages, which developed a Medicines at Transitions Intervention (MaTI) toolkit to help the way heart failure patients are supported with their medicines. MaTI was developed through a process of co-design with patients and healthcare staff, with the aim to improve the safety and continuity of medicines at care transitions, and subsequently reduce mortality and readmission to hospital.
The MaTI toolkit will be evaluated in the ISCOMAT Trial. This is a cluster randomised controlled trial (cRCT), which randomized 43 secondary care cardiology services (clusters) to implement either the MaTI or continue to deliver their usual care.
Cohort:
A total of 1615 men and women aged over 18, who were admitted to a participating hospital with a diagnosis of heart failure and evidence of at least moderate left ventricular systolic dysfunction confirmed within the last 5 years, were recruited between 06/2018 and 03/2020 and consented to share their information with NHS Digital.
Outcome and data required:
The main (primary) outcome is all-cause mortality and Heart Failure related hospitalisation within 12 months of recruitment. This is in line with the aim of the MaTI intervention, which is to reduce mortality and reduce readmissions to hospital.
The key secondary outcome is continued prescription of guideline indicated therapy at 12 months post recruitment. This will help identify if the MaTI toolkit increases the number of heart failure patients who are receiving appropriate heart failure medication, after they are discharged from hospital to home.
Other secondary outcomes will help identify any other potential benefits of the MaTI toolkit, and include: time from registration to death, or to heart failure rehospitalisation; length of time on guideline recommended medications from registration, patient understanding of medicines and satisfaction with medicines related care; number of days alive and out of hospital; hospitalisations; death due to specific causes.
A parallel cost-effectiveness analysis will include Hospital Episode Statistics (HES) Admitted Patient Care (APC), HES Critical Care (CC), HES Outpatients, Emergency Care Data Set (ECDS), Civil Registration (Deaths) Secondary Care Cut (CRD SCC) to derive a costs per all-cause deaths prevented and re-hospitalisation prevented, alongside cost-effectiveness of intervention.
Data to support primary and secondary outcomes as outlined above is available in HES, ECDS, CRD SCC, and the Medicines Dispensed in Primary Care (NHSBA) data.
Data will also be sought from the National Heart Failure Audit via the National Institute of Cardiovascular Outcomes Research (NICOR), clinical data directly from participating hospitals, and patient reported outcomes direct from participants.
Patient-level data is needed from HES, ECDS, linked Civil Registration Mortality Data and Prescribing data to allow the trial team to link these data with the NICOR data, clinical data and patient reported outcomes for our cohort of participants. The linked datasets will subsequently be used as the analysis dataset for the ISCOMAT trial.
Data is requested from the time the first consenting and eligible participant was admitted to hospital (June 2018) until 12 months after the last participant was registered (March 2021). These years are required in order to achieve the outcomes listed above. The hospitals taking part in ISCOMAT are spread throughout England and therefore necessitates the geographical spread of data requested.
Obtaining data held in electronic health records will provide a complete dataset to answer the primary and secondary outcomes. The trial was designed to use data from routine sources as it was determined that this would be the least intrusive way to answer research questions for participants and to also minimise burden on research staff at hospitals.
Data requested for this application is minimised as much as possible. This data sharing agreement relates to the cohort of 1615 (1615 out of 1641 recruited consented to share data with NHS Digital) men and women aged 18 and over at time of admission, with a diagnosis of heart failure with evidence of at least moderate left ventricular systolic dysfunction confirmed within the last 5 years. The specific data requests relate to this cohort and any admissions to hospital and instances of death, including cause of death between the date of registration and 12 months. Obtaining prescribing datasets also supports key secondary outcomes on length of time participants are prescribed guideline indicated therapies. The data requested is proportionate to the data required to answer the primary and secondary outcomes.
Organisations involved:
Bradford Teaching Hospitals NHS Foundation Trust (BTHFT) and the University of Leeds (UoL) are joint controllers. The data is processed at the University of Leeds.
The Chief Investigator is a professor of cardiovascular medicine and honorary Consultant Cardiologist. His substantive employer is the University of Leeds, and he has an honorary contract with BTHFT. The Clinical Trials Research Unit (CTRU), at the University of Leeds, is co-ordinating the trial and is responsible for trial design and conduct, including protocol development, ethics approval, trial monitoring, data collection and ongoing management, and statistical analysis and reporting. All data for the cohort of patients recruited to the trial is processed and stored at the CTRU. The Academic Unit of Health Economics (AUHE) at the University of Leeds will perform the cost effectiveness analysis, and data will be transferred to the trial health economist for processing. The CTRU and the AUHE have both completed the Data Security and Protection Toolkit (DSPT) which evidences each department's compliance against the National Data Guardian’s 10 data security standards.
ISCOMAT is delivered by a multidisciplinary research collaboration between BTHFT (as NHS lead and Sponsor), the University of Bradford and University of Leeds. The collaboration includes patient representatives, and a Patient Led Steering Group is actively involved in conduct and oversight. A contract is in place between the funder (Department of Health) and BTHFT (NHS Lead), and a collaboration agreement is in place between the BTHFT, the University of Leeds, and the University of Bradford. The ISCOMAT trial is the fifth in a series of interlinked work packages that comprise a NIHR Programme Grant for Applied Research (PGfAR). An earlier work package (1B) successfully obtained data from NHS Digital for a cohort of 53 participants (DARS-NIC-40493-G5Y6K). The University of Bradford are not receiving, or otherwise accessing and processing, any data under this data sharing agreement. Processing activities are undertaken at the University of Leeds as fully outlined in the Processing Activities section.
Decisions relating to the processing of personal data remain with BTHFT and UoL. University of Leeds and BTHFT as joint controllers confirm that they will ensure a GDPR compliant, publicly accessible transparency notice is maintained throughout the life of this agreement.
The trial is funded by the NIHR Programme Grants for Applied Research (RP-PG-0514-20009). The trial funder does not make decision on the processing of personal data, and has no role in study design, data collection, data analysis, data interpretation, or writing of the final report.
Expected Benefits:
Heart failure affects 26 million people globally and approximately 900,000 people in the UK. With the incidence of new diagnoses of the condition increasing, the ISCOMAT trial results have the potential to inform the treatment and care of heart failure patients when especially vulnerable during a care transition. The benefits from this dissemination will not be realised for health care until the main results of the trial are published in 2022.
The benefits focus on patient care improvement, and dissemination will be led by the trial research team, including programme management group, trial management group and trial steering committee. The results, placed in open-access peer reviewed publications, are hoped will provide an evidence base with potential to impact on clinical guidance, including National Institute for Health and Care Excellence (NICE) guidelines on heart failure and medicines related care. It is hoped that benefits for health service commissioners will include provision of evidence to support future commissioning of community pharmacy services as well as the need for more effective optimisation of heart failure treatment, with associated health benefits. The aim of this is to ensure that patient medicines management is optimised, and the burden of cardiovascular disease is reduced through preventable cardiovascular events that occur in the period after patients with heart failure are discharged from hospital. Our findings are intended to be, with modifications, transferable to other patient groups who have long-term conditions, frequent hospital readmissions and polypharmacy.
Outputs:
The main analysis is due to be completed by March 2022, with the aim to publish main trial results in late spring, early summer 2022. Results will be published in open access and peer reviewed journals, including publication via the National Institute for Health Research's own journal library, the Lancet, the British Medical Journal (BMJ) and the European Heart Journal (EHJ). Results will also be presented at relevant conferences linked to cardiology and patient safety, including the European Society of Cardiology Congress (Summer 2022). Longstanding and ongoing engagement with stakeholders, including both scientific and policy-making audiences will provide a direct pathway to impact for the outputs of this research.
The Patient-Led Steering Group will inform the dissemination strategy and its members will play an active role in the format and content of academic papers (specifically patient implications) and will present at local, regional and national conferences and wider stakeholder meetings.
Only analyses featuring aggregated data with small number suppression will appear in outputs.
The results and outputs of the study will be further communicated via the study team's websites, social media accounts and through other public promotion of research utilising the study team’s networks, including clinical networks, scientific networks and charitable organisations with heart failure and medicines safety focus.
Lay summaries will be added to the trial website (https://www.bradford.ac.uk/iscomat/) and the trial registry will be updated (https://doi.org/10.1186/ISRCTN66212970). Summaries will also be provided to participating sites. The Use My Data citation - “This work uses data provided by patients and collected by the NHS as part of their care and support” - will be used in all outputs as appropriate, to further acknowledge that the research involved patient data. These outputs will follow the main analysis in 2022.
If the intervention is shown to be effective (as supported by NHS Digital data linkage for primary outcome), the network of champions (patients, staff and other stakeholders) created during the programme will be used to spearhead a plan for adoption and spread. Materials developed during the programme will be made available for wider use.
Processing:
The trial statistician at the Clinical Trials Research Unit (CTRU) will provide the following identifiers: sex, date of birth, postcode and NHS number. Study ID for each participant will be provided to allow linkage of the NHS Digital data to the trial data held by the CTRU. For each participant, date of admission to hospital, and 12 month post registration will be provided. This will provide assurance that minimum data required is obtained. The data will be transferred to NHS Digital via the required secure platform.
NHS Digital will perform an automatic cohort tracing system to search the data provided against existing electronic records to generate a set of records that belong the cohort of 1615 trial participants. This will include linkage of data from Hospital Episode Statistics (HES) Admitted Patient Care (APC), HES Critical Care (CC), HES Outpatients, Emergency Care Data Set (ECDS), Civil Registration (Deaths) Secondary Care Cut, and the Medicines Dispensed in Primary Care (NHSBA) data.
Opt-outs will not be applied, as all participants included in the cohort have consented for their personal data to be shared with NHS Digital to obtain information from their electronic health records, and have not withdrawn their consent for sharing of their personal data with NHS Digital for this purpose.
NHS Digital will transfer the linked record level data to the trial statistician on one occasion. NHS Digital will return pseudonymised data linked using the CTRU supplied Study ID. On receipt of data from NHS Digital, the trial statistician will transfer the data into a secure folder prior to using in statistical software for analysis. As a first step, the trial statistician will perform data cleaning in accordance with CTRU Standard Operating Processes, for example, to ensure no duplicate episodes, no admission after date of death (if deceased). The trial statistician will subsequently link the data obtained from NHS Digital with the trial data held at the CTRU on this cohort, to derive a trial analysis dataset. Linkage of the data will be by the Study ID. Participants in the trial dataset will only be identifiable by their Study ID and all statistical analysis will be conducted with reference to this – there will be no link to patient identifiable data, all data will be pseudonymised.
The statistical analysis will be conducted within a statistical software package in accordance with a Statistical Analysis Plan which will be finalised and agreed by the Trial Management Group in advance of any analysis being undertaken. For the analysis of the primary outcome of all-cause mortality and heart failure rehospitalisation over 12-months follow-up, an indicator will be derived for each participant based on NHS Digital data to indicate whether or not the participant has experienced the primary outcome. The outcome will be compared between the trial arms using a random effects logistic regression model which will include trial data held by CTRU. A similar approach will be taken for the analysis of the secondary outcomes with the most appropriate statistical model chosen based on the type of outcome.
Data items specified in the Health Economics Analysis Plan will be transferred to the trial health economist, via CTRUs Secure File Transfer. Trial statisticians and health economists who access the data are all substantive employees of the University of Leeds, and undergo relevant Data Protection and Information Security training on a regular basis as part of their employment at the University of Leeds.
All data for the cohort of patients recruited to the trial is processed and stored at the CTRU (Organisation Data Service (ODS) is ECC0010), and the Academic Unit of Health Economics (AUHE) at the University of Leeds will perform the cost effectiveness analysis (ODS is 8E218-SEED). No record level data disseminated via NHS Digital for this application will flow from the University of Leeds.
The CTRU server infrastructure is split between two data centres on the main University of Leeds campus. Backups taken from this infrastructure are replicated to the University of Leeds disaster recovery site at the University of York, with tape backups encrypted to AES 256 being kept at Iron Mountain. In all locations data is stored encrypted on disk/ tape. The ability to decrypt is only held by the CTRU. The two disaster recovery sites provide different recovery options. The site at University of York is a warm online copy on disk that can be retrieved instantly for the last 30 days. The Iron Mountain site holds a cold offline copy on tape for 12 months. Neither site can access the data. At the University of York location, the server is University of Leeds own equipment and connects only to the University of Leeds network. This server holds the disaster recovery copy of University of Leeds backups. There is no data processing at this site. The University of York only provides the physical space and power to support this.
Only summary results (no record-level data) will be made publicly available via open access publications, including the NIHR Journals Library publication of the final report. No third party will have access to the data. Data will not be used for any other purposes, and it will not be used for commercial purposes, nor for direct marketing purposes.
The data will only be accessed by authorised members of the team who are all substantive employees of the data controllers through a secure drive on the University of Leeds network. The files will be restricted to those processing data.

Objectives:
There are large variations in the outcomes of orthopaedic surgery across ethnic groups in England and Wales, with patients from Black and Minority Ethnic (BAME) backgrounds struggling to access care and having worse outcomes.
A pilot study at a University Teaching Hospital which serves a large BAME population assessed a locally held database of neck of femur (NOF) fractures. Fracture patterns and outcomes post-fracture in patients from different ethnic backgrounds were compared. South Asian patients were more likely to have the worse fracture types, more likely to be discharged to their own home, and tended to have more co-morbidities and worse mobility. Achievement of best practice tariff (BPT) targets during care was associated with preferentially better outcomes in White patients versus South Asian patients. These findings have not been demonstrated previously.
Traditionally accepted distribution for fracture types, patient demographics and patient mobility may be inconsistent across ethnic groups. As a result, targets for ideal treatment may not be reliably associated with a reduction in mortality in BAME groups. The aim of this data sharing agreement is to compare the outcomes following a NOF fracture across ethnic groups in the UK and explore reasons if any differences are observed which may include physiological differences between groups or other social determinants of health. This analysis is being completed in support of the National Hip Fracture Database service evaluation activity to improve the quality and cost-effectiveness of hip fracture care; and to reduce the incidence of the injury by improving secondary prevention. The NHFD has section 251 approval in support of its aim "To support audit, service evaluation and quality improvement activity by NHFD, NHFD participant sites and approved third parties". The analysis being undertaken by the University of Leeds is in the capacity of a service evaluation by an approved third party.
Pseudonymised data will be acquired from the NHFD. This will be linked with Hospital Episode Statistics (HES) Admitted Patient Care (APC) and Civil Registration (Deaths) data, as well as equivalent hospital episode data for patients attending Welsh hospitals using a unique study ID given to all patients in the NHFD. Ethnic groups deemed to have high stability from census data will be used to estimate ethnic group specific demographics, fracture types and risk factors for mortality. Ethnic groups assessed will be White (British/ Irish/ Other), South Asian (Indian, Pakistani, Bangladeshi), Asian (Chinese), Caribbean and African.
Data required from NHS Digitals HES APC and Deaths datasets includes demographic data (e.g. Age on admission, Ethnic Category, Sex of patient, Index of Multiple Deprivation, Lower Super Output Area (LSOA)), as well as data relating to the diagnosis of, procedures relating to, and subsequent outcomes of patients with NOF fractures. These demographic covariates will be controlled for to study the effect of ethnicity.
The University of Leeds will link NHFD data with the pseudonymised NHS Digital data with the equivalent pseudonymised Patient Episode Database for Wales (PEDW) data to investigate outcomes following NOF fracture by ethnicity. Pseudonymised NHFD data includes variables relating to fracture side, classification and pathology; surgical variables; post-operative outcomes; BPT criteria (geriatrician/ specialist fall/ multi-disciplinary assessments); discharge variables (when and where) and follow-up variables (mobility, medications, residential status).
Selecting smaller geographical areas rather than requesting national data was considered but is not feasible because it would affect the robustness of the findings. The previous pilot study conducted in a geographical location with a high South Asian population included only 53 South Asian patients and even fewer from other ethnic backgrounds from a sample of 1,520 patients. A national data set is required to draw firmer conclusions and study patients from various BAME backgrounds. The geographical spread is required to be England and Wales specifically since this is the geographical coverage of the NHFD. The aim is to include all NOF fractures and the inclusion criteria are a hip fracture on the NHFD between 01/01/2009 and 01/02/2021. This timeframe is necessary to have robust, large scale data to be able to draw accurate conclusions. The data requested is the minimum data set required to achieve the aims of the service evaluation. There are no alternative, less intrusive ways of achieving the purpose.
The NHFD itself is an audit which aims to improve the processes of care and the outcomes for patients with hip fractures, as well as ensure reliable information on quality of care and outcomes is available for patients and the public. The outcomes of this service evaluation align with the outcomes of the NHFD, but include a break down by ethnicity, including specific demographic factors not covered by the current NHFD. The primary outcome will be patient mortality at 365-days post fractured NOF for BAME patients as compared to the White population.
The secondary outcomes will be to assess:
- Differences in mortality at 30- and 120-days
- Associations of clinical comorbities with increased mortality
- Differences in fracture type
- Differences in mobility and residential status
- If BPT achievement is associated with a different outcome
The University of Leeds will undertake this work to support service evaluation and quality improvement activity by the NHFD. University of Leeds will be the controller and processor of this data. HQIP act as data controllers for the NHFD but do not have access to linked data analysed by researchers at University of Leeds. The project is funded by the Royal College of Surgeons of Edinburgh (RCSEd). RCSEd do not determine the purpose or the manner in which the data will be processed.
The justification for processing the data by University of Leeds is Article 6(1)(e) of the GDPR: (processing is necessary for the performance of a task in the public interest or in the exercise of official authority vested in the controller).
The justification for the processing of the special category data (health data) by University of Leeds is Article 9(2)(j) of the GDPR: (processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law which shall be proportionate to the aim pursued, respect the essence of the right to data protection and provide for suitable and specific measures to safeguard the fundamental rights and the interests of the data subject.
There is no wider project or collaboration planned.
Expected Benefits:
This evaluation is hoped to lay the foundations in ensuring health services are allocated appropriately and fairly to all accessing treatment in the NHS. The evaluation aims to assess the difference in outcome following neck of femur (NOF) fracture for patients from Black and Minority Ethnic (BAME) backgrounds, and inform National Hip Fracture Database (NHFD) policy on data collection. It intends to provide evidence for the requirement of ethnicity data collection, therefore allowing monitoring to ensure all patients from all backgrounds receive optimal care and treatment following a neck of femur fracture. Trusts will be able to assess the percentages of ethnic minority patients and allocate resources as appropriate.
Through publication in the NHFD Annual Report, Trusts will have easy access to the findings of this evaluation. Publishing in peer-reviewed journals is also anticipated to allow greater discussion of the strengths and weaknesses of the results and will provide the benefit of peer-review of the work from third parties. The University of Leeds will identify risk factors as a means of identifying future areas for investigation.
An example of a future area for investigation that may be generated from this evaluation is the identification of a variation in the incidence of different fracture types between ethnicities. If such a variation does exist, it is anticipated that it will be possible to identify morphological differences in the hip that may account for this. Currently, it is recommended all patients with a displaced intracapsular femoral neck fracture receive a cemented implant. However, morphological differences in the hip may mean certain ethnicities would benefit from a different type of implant. Therefore, patients from BAME backgrounds may be suffering from a higher rate of complications from the use of certain implants, which is likely to lead to costly revision surgery. If the data demonstrates such an effect, it will provide useful information for Trusts to allocate healthcare resources.
It is also known that patients from BAME backgrounds are more likely to suffer from deficiency of Vitamin D, as such bisphosphonate treatment may be less effective in these patients. If the data shows an unexpected effect of bisphosphonate therapy in BAME patients, this may enable future research studies to identify the causes for this which could in turn lead to a trialling of alternative therapies.
Outputs:
The NHFD produce an annual report in which the findings of this evaluation are expected to be included. A report to the Royal College of Surgeons of Edinburgh (RCSEd) as the funding body will also be prepared.
To reach a wider scientific audience, submission to peer reviewed journals are intended to be prepared including to The New England Journal of Medicine, The Lancet, British Medical Journal, and Bone and Joint Journal. It is planned that presentations at Orthopaedic conferences including the American Academy of Orthopaedic Surgeons and British Orthopaedic Association will be prepared.
All outputs will be aggregated with small numbers suppressed in line with the HES analysis guide.
This evaluation is the start of a process of ensuring all patients receive optimal care and treatment following a neck of femur fracture. Members of the study team previously conducted a patient involvement focus group with Bradford residents. The overwhelming message was that care should be tailored to meet individual needs. Patient and Public Involvement (PPI) and focus groups are intended to be consulted to determine the best way to reach patients from various backgrounds with the results of this evaluation. Focus groups consulted in the lead up to this project were surprised that hip fracture care is not more patient specific already. 'Ask the Researcher' events will be held to reach a wider public audience. The aim is to ensure that knowledge developed by this evaluation improves outcome following hip fracture.
Outputs are planned to be realised December 2023.
Processing:
Crown Informatics will send NHS Number, date of birth, Full postcode, Name and FFFAP ID (a unique National Hip Fracture Database (NHFD) person identifier) for all patients in the NHFD database with a neck of femur (NOF) fracture to NHS Digital and NHS Wales Informatics Service (NWIS). Pseudonymised data with the same FFFAP ID will flow to researchers at University of Leeds, with NHS Digital providing HES APC and Civil Registrations (Deaths) data, and NWIS providing Patient Episode Database for Wales (PEDW) data. HES APC data will be filtered to include only the spell relating to the neck of femur (NOF) fracture admission, based on the NOF fracture diagnosis code.
Crown Informatics will also send an encrypted version of pseudonymised NHFD data to the study chief investigator (CI) at the University of Leeds who will transfer data to Leeds Institute of Data Analytics (LIDA). The CI nominates LIDA members to receive the password for data decryption from Crown Informatics.
The pseudonymised data from NHS Digital, NHS Wales Informatics Service and the NHFD will be linked using the FFFAP ID inside the LASER cloud platform at the University of Leeds as needed for analysis.
Patients in the ethnic minority groups will be matched independently to a cohort of the control population (White). Odds of dying at 30 days, 120 days and 365 days respectively will be analysed between White and ethnic minority groups with adjustment for all clinically relevant covariates.
Data processing is carried out by substantive employees and honorary contract holders from the University of Leeds who have been appropriately trained in data protection and confidentiality. Researchers who work on the pseudonymised data set do not have access to the list of patient identifiers sent to NHS digital for linkage purposes.
There is no requirement, and no attempts will be made to identify individual patients. The full Date of Death is required to be able to calculate Kaplan Meier survival curves. Researchers will not be linking NHS Digital data with any other datasets except those listed above. There will be no capacity for researchers to identify any individual patients.
Data will be held at the LIDA, University of Leeds on the LASER cloud platform which is supported by Microsoft Azure. Microsoft Limited supply Cloud Services for the University of Leeds and are therefore listed as a data processor. They supply support to the system, but do not access data. Therefore, any access to the data held under this agreement would be considered a breach of the agreement.
Access to the data is only granted to users who have an authorised platform account and the correct permissions to access the project-specific secure environment. To access this secure environment, those authorised users will log into the platform using their credentials and multifactor authentication. Once logged in, they can remotely connect to the secure environment. The secure environment does not permit internet connection, clipboard sharing (copy+paste between systems), nor any other mechanism to access/transfer files unless via means that are documented in the platforms Information Security Management System.
In order to protect patient confidentiality, when presenting results calculated from HES record level data, outputs will contain only aggregate level data with small numbers suppressed in line with HES Analysis Guide. When publishing HES data, the University of Leeds must ensure that:
· cell values from 1 to 7 are suppressed at a local level to prevent possible identification of individuals from small counts within the table.
· Zeros (0) do not need to be suppressed.
· All other counts will be rounded to the nearest 5.
Data will not be made available to any third parties other than those specified except in the form of aggregated outputs with small numbers suppressed in line with the HES Analysis Guide.

Objectives:
The objective for processing of this data is to undertake research about health-related quality of life (HRQoL) in patients with myocardial infarction (MI; heart attack). Specifically, University of Leeds wish to investigate the relationship between HRQoL and clinical outcomes in this population. The study is entitled the EMMACE Study: (Evaluation of the Methods and Management of Acute Coronary Events). It is a national longitudinal consented cohort of patient reported outcomes of MI.
More people than ever are surviving their initial presentation with MI. Yet, many will have recurrent cardiovascular events, and some will die prematurely. Whilst HRQoL is an important patient-facing outcome after MI, there is a paucity of information about its association with subsequent clinical events. The overarching aim of this study is to enhance the EMMACE study consented cohort data using national healthcare data (HES and Civil Registration Mortality data) to investigate the association of changes in HRQoL and subsequent clinical outcomes (fatal or non-fatal ) following MI including stroke, recurrent MI, heart failure, atrial fibrillation, deaths following MI.
The University of Leeds is a public authority responsible for conducting scientific research for academic and public benefit. Data in the EMMACE Study is processed to enable the University of Leeds to perform its public task. University of Leeds rely on the following legal bases for processing data under the General Data Protection Regulation:
Article 6 (1)(E): Processing is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller. Few centres have sufficient patient through-put to provide this information.
Article 9 (2)(J): Processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes in accordance with Article 89(1) based on Union or Member State law which shall be proportionate to the aim pursued, respect the essence of the right to data protection and provide for suitable and specific measures to safeguard the fundamental rights and the interests of the data subject.
The University of Leeds EMMACE study aims to investigate health related quality of life in patients with myocardial infarction. University of Leeds wish to investigate the relationship between health related quality of life and clinical outcomes in this population.
COHORT:
The trial has finished recruitment to participants. EMMACE 3 and EMMACE 4 are separate studies and not follow on studies.
The number in the cohort for EMMACE 3 is 5556 participants, recruited between 1st November 2011 and 17th September 2013.
The number in the cohort for EMMACE 4 is 9343 participants, recruited between October 2013 and 24th June 2015
For both trials the total is 14,899 participants.
The specific objectives of the research project are:
1. To describe MI patients according to their changes in HRQoL(from occurrence of MI to discharge, 30 days follow up, 6 months, and 12 months) and determine factors associated with these changes.
2. To summarise the incidence of fatal and non-fatal health outcomes amongst patients and determine if there are common patient clusters with respect to these outcomes.
3. To investigate whether changes in HRQoL have differential impact on fatal and non-fatal clinical outcomes.
4. To investigate the association of quality of care, cardiac rehabilitation, medications, patient characteristics, socioeconomic status, changes in HRQoL with mortality
The 4 objectives which will use the cohort are as follows;
Objectives 1, 3 and 4 will use 9566 patients from both the EMMACE 3 & EMMACE 4 studies who have:
- ST-Elevation Myocardial Infarction (STEMI), which is a very serious type of heart attack during which one of the heart's major arteries that supplies oxygen and nutrient-rich blood to the heart muscle is blocked. ST relates to a section on the ECG test and may indicate whether a heart attack has taken place.
- Non-ST-elevation myocardial infarction (NSTEMI), which is less serious than an STEMI as the supply of blood to the heart may be only partially, rather than completely, blocked.
Please note that this is a subset from the total of 14,899 but only focusing on patients with STEMI and Non STEMI
Objective 2 will use all 14,899 patients from both studies EMMACE 3 & 4 including those without STEMI or NSTEMI
The EMMACE data cohort contains patient data on changes in HRQoL from MI to discharge, 30 days follow up, 6 months, 12 months measured using EQ-5D 3L questionnaire as well as information on cardiac rehabilitation, medications and patient characteristics - however - in order to meet the study objectives, the study team need to enhance the EMMACE dataset through linkage with HES and Civil Registration Mortality Data to determine the subsequent fatal and non-fatal outcomes following MI.
A detailed justification for the request of this level of data is outlined below:
The EMMACE study represents the largest contemporary national longitudinal study of patient reported outcomes and medications data for acute coronary syndrome. The study was designed to improve understanding of the effect of quality of care on health-related outcomes for patients hospitalised with acute coronary syndrome (ACS). The EMMACE studies, with consent for further linkage to electronic healthcare records, were given favourable ethical approval by Leeds (West) Research Ethics committee (REC reference: 10/H131374, 13/YH/0277 and 12/WM/0431).
The EMMACE dataset contains patient reported data at admission, 1 month, 6 months and 1 year concerning patient related quality of life measured by EuroQol 5-dimension (EQ-5D-3L) questionnaire.
All patients were consented to enter the study and for their self-reported data to be linked to future electronic health record data.
EMMACE has already been successfully linked to data from the national heart attack registry (Myocardial Ischemia National Audit project, MINAP) thus providing information about hospital treatment for MI and comorbidities.
Further information in the form of a GDPR compliant transparency information leaflet was sent to all participants.
Whilst the EMMACE study provided information on determinants and trajectories of HRQoL following MI, questions remain on the association of changes in HRQoL and subsequent clinical patient outcomes for patients with MI.
The EMMACE data are limited to the extent that they do not capture the full range of quality of care, comorbidities, patient characteristics, clinical diagnosis, socioeconomic status, treatments and patient outcomes. Thus, the study team are not able to investigate the relationship between HRQoL, socio-economic status, quality of care, clinical diagnosis, treatments and fatal and non-fatal clinical outcomes.
This project has been funded by the British Heart Foundation (BHF) (PG/19/54/34511) to enhance the EMMACE data by linking it with existing electronic data on hospital episodes from HES and Civil Registration Mortality Data - facilitated by NHS Digital.
To summarise the incidence of fatal and non-fatal health outcomes amongst patients and determine if there are common patient clusters with respect to these outcomes and factors associated with these clusters, the EMMACE data will be linked electronically to Hospital Episodes Statistics and Civil Registration Mortality Data.
The HES data requested will include information on cause-specific hospital admissions, all HES records for the patients (i.e. their historical records and prospective ones after they entered EMMACE), any hospital diagnoses, clinical information and treatments.
These repeated cause-specific admissions, episodes and spells will be used to determine the longitudinal AMI patient phenotypes, patient transitions over time, and factors associated with these transitions. Non-fatal outcomes will include all hospital diagnoses such as heart failure, stroke, atrial fibrillation and acute coronary syndrome, with the fatal outcome being all-cause mortality. University of Leeds will investigate the effects of patient characteristics, socioeconomic status, diagnosis, changes in HRQoL, comorbidities, treatments on patient class membership and transition probabilities hence this data request from HES records.
To investigate the association of quality of care, cardiac rehabilitation, medications, treatments, patient characteristics, socioeconomic status, changes in HRQoL with mortality. EMMACE data will be linked electronically to Civil Registration Mortality data for information on cause specific mortality and date of death. Mortality data will be required at individual patient level about the occurrence, timing and causes of any death. The exact date of death will be required to calculate the survival time between date of entry into the EMMACE study and date of death. A survival time for those who have not die but are censored will be required.
To ensure comprehensive information on all confounders, University of Leeds are requesting individual patient level HES data on in-patient hospitalisations, patient demographic characteristics (age of patient, sex of patient, ethnicity), socio-economic factors (IMD indices, smoking status, employment status) information about diagnoses and operations, dates of admission and discharge, where patients were treated, comorbidities, revascularization procedures and treatments.
The research will be undertaken by the established Cardiovascular Epidemiology Research Group within the Leeds Institute of Cardiovascular and Metabolic Medicine, and physically located in the Leeds Institute for Data analytics at the University of Leeds.
The research group has a remit of using large scale routine data (HES) and clinical registries (MINAP registry) alongside advanced analytical epidemiological techniques to better understand and improve the quality of care of patients with cardiovascular disease.
Expected Benefits:
Whilst planned analyses have the potential to achieve high impact peer reviewed publications, it is the clinical implications of the results for healthcare professionals, patients and regulators that are of greater virtue.
The results from the proposed study will help answer major gaps in the knowledge base on the associations between changes in HRQoL and subsequent health outcomes. Identifying precisely in whom worse (or better) outcomes may occur will permit the design and testing of novel interventions targeted specifically at common, and potentially previously unknown, consequences of a heart attack for patients with specific health related quality of life trajectories.
The aim of the EMMACE study is to improve the quality of life and clinical outcomes of patients with MI. The planned research will provide a unique and comprehensive insight into the relationship between changes in HRQoL and clinical outcomes among patients with MI. HRQoL is a patient reported outcome measure (PROM) which can detect change in risk of events for patients, and potentially serve as a predictor of future risk (using patient-facing data capture tools). Understanding the association between changes in HRQoL and health outcomes, and precisely in whom worse (or better) outcomes may occur will permit the design and testing of novel intervention to reduce premature death from MI.
Results from this research will help design interventions to improve quality of life and cardiovascular outcomes in survivors of heart attacks. The results will be used to inform the UK Clinical Commissioning Groups (CCGs) who work in partnerships with hospitals and are responsible for the commissioning of specialist services including acute cardiac care.
In this study, through linkage to HES and Civil Registration Mortality data, University of Leeds will be able to classify patients into particular phenotypes (or disease risk patterns) using fatal (deaths) and non-fatal outcomes (stroke, heart failure, atrial fibrillation, re-infarction and any other hospitalisations). This will allow University of Leeds to determine the types of patients who may benefit from more intensive care, to improve their quality of life and survival.
Outputs:
The planned analysis of the EMMACE study will be disseminated nationally and internationally in peer – reviewed open access research journals (such as European Heart Journal, Heart, BMJ); national and international research conferences, departmental seminars, through the media and stakeholder meetings with patients. The EMMACE researchers have established relations with the International Quality of Life Society (ISOQOL) through which study findings will be disseminated. Furthermore the Cardiovascular Epidemiology research team has established connections with numerous relevant groups through which findings will be disseminated to the NHS as well as patients, including the European Society of Cardiology, the British Cardiovascular Society and NICE. The EMMACE study dissemination strategy will be as follows:
Peer-reviewed publications
Target publications for 2020 are:
Paper 1: Multi-morbidity and health related quality of life after myocardial infarction: A nationwide longitudinal patient-reported outcomes study.
In this paper University of Leeds will look at the association of multi-morbidity and HRQoL following MI.
Paper 2: Cardiac rehabilitation, exercise dose, health related quality of life and mortality after myocardial infarction: A nationwide longitudinal patient-reported outcomes study.

Processing:
All organisations party to this agreement must comply with the Data Sharing Framework Contract requirements, including those regarding the use (and purposes of that use) by "Personnel" (as defined within the Data Sharing Framework Contract i.e: employees, agents and contractors of the Data Recipient who may have access to that data).
Presently the EMMACE data are stored in two physically different secure locations.
All EMMACE 3 data, including identifiable data such as NHS number, sex and date of birth are stored at the University of Leeds. EMMACE 3 data at the University of Leeds is managed by Leeds Institute of Data Analytics (LIDA) who have control of the data, are responsible for supplying cohort information to NHS Digital and linking NHS Digital data to all non-identifiable data using study ID only. LIDA will supply pseudonymised data to the statisticians in the Cardiology Epidemiology group at the University of Leeds who will analyse the data. Statisticians in the Cardiology Epidemiology group do not have access to personal data but to study ID only.
EMMACE 4 data, including identifiable data such as NHS number, sex and date of birth are stored at the Leeds Teaching Hospitals NHS Trust (LTHT). This is for administrative purposes and for use in facilitating ongoing data linkages.
Access to this environment is controlled by two factor authentication and is granted a need only basis. All data received into this solution is via secure transfer and in accordance with all data sharing agreements. Data will be encrypted in transit and at rest. The data is transferred directly to the processing platform where any agreed processing will take place. Any data in this platform is deleted in accordance with any processing agreement.
All sites and data centres are protected by CCTV. Access control is limited via key fobs to office areas and safe rooms. All networks are segmented and where required for security prevent access, data flow, external access etc. All networks internally and externally are tested on a monthly basis for vulnerabilities.
DATA FLOW INTO NHS DIGITAL:
Leeds Institute of Data Analytics at University of Leeds will send the following identifiers to NHS Digital for the EMMACE 3 Cohort:
• NHS Number
• Sex
• Date of Birth
• Study ID
LTHT will send the following identifiers to NHS Digital for the EMMACE 4 Cohort:
• NHS Number
• Sex
• Date of Birth
• Study ID
All identifiers for participants who have withdrawn from further follow up from the EMMACE 3 and 4 studies will be removed from the data files prior to sending to NHS Digital.
The EMMACE data will be linked to HES and Civil Registration Mortality data for the period November 2011 to 2020 (or latest possible date) by NHS Digital acting as the trusted third party. NHS Digital will return data to the University of Leeds that includes (for patients with prior and/or subsequent hospitalisations) corresponding HES records and corresponding cause of death and date of death for patients who have died. University of Leeds require only Study ID from NHS Digital as the identifier - NHS Number is not required to be returned..
University of Leeds have requested data from 2010/11 to present as the research study EMMACE recruited patients with Myocardial Infarction (MI) from 1st November 2011. In this current research one of the objectives is to summarise the incidence of fatal and non-fatal health outcomes amongst the patients and determine if there are common patient clusters with respect to these outcomes. To undertake this research work University of Leeds will require the episode and spells for periods of care of patients in the research study (EMMACE) who consented for their data to link to electronic health records, clinical information and diagnosis will be required to determine the fatal and non fatal outcomes and duration of outcomes. Geographical information from HES data is required to determine geographical variations in outcomes after Myocardial infarction.
One of the objectives is to investigate the association of cardiac rehabilitation, medications, treatments, patient characteristics, socio-economic status, and changes in HRQoL with mortality. In order to undertake this work, patient data, socioeconomic data, treatments from HES is required. IMD domain and overall ranks scores will be required to look at the relationship of specific domains with HRQoL.
The linked (EMMACE/HES/Civil Registration Mortality) data - the analytical cohort - will be stored separately from the EMMACE cohort that contains patient identifiers.
That is, the analytical cohort (excluding NHS numbers) will be stored in a restricted directory within the University of Leeds password protected secure storage area network (SAN).
The University of Leeds Information Security Policy has been fully implemented and has been drawn up in line with ISO 27001 The University of Leeds are DSPT accredited. The data for this study is considered personal and its storage and sharing will abide by the University of Leeds data protection and sharing policies. The data will only be accessible to authorised individuals in the study team and will only be used for the purpose of this project. Data will not be used for commercial purposes or provided in record level form to any third party or used for any direct marketing.
There will be no data linkage undertaken with NHS Digital data provided under this agreement that is not already noted in the agreement.
Data will only be accessed and processed by substantive employees of University of Leeds and will not be accessed or processed by any other third parties not mentioned in this agreement.

Objectives:
The overall aim of LP-MAESTRO is to evaluate the cost-effectiveness and efficiency of particular
configurations of liaison psychiatry services for specified target populations. To do this, an innovative approach based upon linking routinely collected patient-level data and using economic modelling with the resulting aggregated data will be developed and evaluated.
Workstream 2 – Phase 1 (WS2P1) focuses on 11 acute hospitals in England that were identified within
Workstream 1 of LP-MAESTRO and the Liaison Psychiatry Survey England 2015 as not having a Liaison
Psychiatry service. Of those 11 hospitals, 8 gave approval (see approval letters associated with this application) for their data to be included within this study as follows:
-- St Mary’s Hospital (Isle of Wight NHS Trust)
-- James Paget University Hospital (James Paget University Hospitals NHS Foundation Trust)
-- Diana, Princess of Wales Hospital (North Lincolnshire and Goole NHS Foundation Trust)
-- Scunthorpe General Hospital (North Lincolnshire and Goole NHS Foundation Trust)
-- Rotherham Hospital (Rotherham NHS Foundation Trust)
-- Pilgrim Hospital (United Lincolnshire Hospitals NHS Trust)
-- Lincoln County Hospital (United Lincolnshire Hospitals NHS Trust)
-- County Hospital (University Hospitals of North Midlands NHS Trust) - previously Stafford Hospital (Mid Staffordshire NHS Foundation Trust)
The NHS trusts for the following hospitals did not provide approval within the required timescale and are therefore not included within this application:
-- Basingstoke and North Hampshire Hospital (Hampshire Hospitals NHS Foundation Trust)
-- Royal Hampshire County Hospital (Hampshire Hospitals NHS Foundation Trust)
-- Luton and Dunstable Hospital (Luton and Dunstable University Hospitals NHS Foundation Trust)
For patients with an A&E attendance or Inpatient episode (Index Episode) at one of the 8 included hospitals within the defined index period (1st April 2013 – 31st March 2014), A&E attendances, Inpatient admissions and Outpatient appointments will be obtained from Hospital Episode Statistics (HES) for the period from 1st April 2012 - 31st March 2015 (i.e. 1 year prior to the index period, the index period itself and 1 year following
the index period).
For patients included within the HES data, the study will determine whether primary care data exists for the patients within TPP’s ResearchOne database. If so, a defined set of primary care data will be obtained for these patients for the period prior to 1st April 2014. Additionally, a mapping file will be produced by NHS Digital and supplied to the University of Leeds to enable the HES data for a specific patient to be linked to the
corresponding primary care data (if present).
From the linked data, pathways for patients attending the 8 hospitals without a Liaison Psychiatry service will be constructed.
Workstream 2 – Phase 2 (WSP21) focuses on hospitals in England that were identified within Workstream 1 of LP-MAESTRO and the Liaison Psychiatry Survey England 2015 as having a particular configuration of Liaison Psychiatry service. To enable pathways to be constructed for patients attending these hospitals that consider the interaction of patients with the Liaison Psychiatry services in these hospitals, data is additionally
required from the NHS trusts that run these services. A variation to the linkage methodology proposed for WS2P1 would be required to support the use of these additional data sources. Accordingly, WS2P2 is not covered by this application and will be subject to separate approval and application.
For the avoidance of doubt, this application relates ONLY to WS2P1.
Patient pathways constructed within WS2P1 and WS2P2 will be tracked and the cost of each to the health care sector calculated using national data sources. A whole system perspective will be adopted in order to determine if there is an association between the presence and configuration of liaison services and health care utilisation by patients. Metrics will include emergency admissions, occupied bed days and length of stay.
Each metric will be analysed by age band.
Aggregate figures on A&E and Inpatient admissions (for the named hospitals) on which to estimate sample size are not publicly available. This data is required in order to estimate the numbers that can be expected in the study. General figures on the number of A&E attendances and inpatient admissions in a given year are published by HSCIC at the level of the trusts that operate these hospitals (see http://www.hscic.gov.uk/catalogue/PUB16728/acci-emer-atte-eng-2013-14-pla.xlsx and
http://www.hscic.gov.uk/catalogue/PUB16719/hosp-epis-stat-admi-prov-leve-2013-14-tab.xlsx). These figures provide an indicative upper bound on the number of A&E attendances and inpatient admissions that can be expected at any of the hospitals operated by that trust in a given year.
For 2013-2014, these figures were the following:
- Isle of Wight NHS Trust: A&E Attendances - 59,494, Inpatient Admissions - 28,263
- James Paget University Hospitals NHS Foundation Trust: A&E Attendances - 67,726, Inpatient Admissions
- 58,144
- North Lincolnshire and Goole NHS Foundation Trust: A&E Attendances - 137,841, Inpatient Admissions -
107,403
- Rotherham NHS Foundation Trust: A&E Attendances - 74,458, Inpatient Admissions - 74,313
- United Lincolnshire Hospitals NHS Trust: A&E Attendances - 144,788, Inpatient Admissions - 146,845
- University Hospitals of North Midlands NHS Trust: A&E Attendances - 119,709, Inpatient Admissions -
157,605
Yielded Benefits:
Local benefits might be seen as soon as a year after publication. National benefits are more likely to be seen over a 2-5 year timescale. Requested HES data was made available by NHS Digital on 16th November 2018. However, the study are currently awaiting additional required data from both NHS Digital and The Phoenix Partnership before analysis can commence.
Expected Benefits:
The results of this application will be used to determine the cost-effectiveness and efficiency of different liaison psychiatry configurations. Based on these results, the study will prepare two types of report to inform the commissioning and provision of general hospital mental health services (expected date: 2019). One report will be aimed at local commissioners, to aid them in making decisions about local service funding. The other will be aimed at national bodies and especially NHS England, where there is an active interest in such services.
The benefits will be measured through changes in the profile of mental health services, in line with report recommendations, as determined by the yearly national survey of such services currently funded by NHS England and Health Education England. These results should influence provision of mental health services in every acute hospital in the NHS. Since a typical mental health service of that sort sees five thousand or so cases a year, the benefits should accrue to many hundreds of thousands of patients.
Local benefits might be seen as soon as a year after publication. National benefits are more likely to be seen over a 2-5 year timescale.
Outputs:
- The study will publish an academic paper (describing the findings in relation to patient outcomes and cost effectiveness)in a reviewed health services research and probably also in a mental health journal.
The audiences will be [a] academics with an interest in liaison psychiatry services [b] academics with an interest in use of routine data to answer health services questions.
These papers will be submitted by the end of the project. Due to delays in data access a project extension request was submitted to NIHR. Intention to approve a project extension has now been received from NIHR. Once formally approved by the Department of Health, the end date of the project will be 30th June 2019. The study will submit to open-access journals to maximise coverage.
- The funders (NIHR) require a final report of main project in the form of a monograph, at the end of the project. The monograph will be published in the NIHR library, which is widely accessed by academics with an interest in applied health research.
- The study will write two discussion papers for health service commissioners by the end of the project – describing the findings in relation to evidence on the effectiveness of liaison psychiatry services, and our findings on the use of routine data to evaluate services.
- A final methodological paper will describe the project as proof of concept for future research projects using linked data from primary and secondary care settings by the end of the project.
Processing:
A summary of the data flows, which are performed using either: i) NHS Digital's Secure File Transfer (SEFT) or ii) University of Leeds LICTR's Secure File Transfer (SFT), is provided below:
1. University of Leeds provides TPP (SystmOne) with the cryptographic salt (via SFT)
2. University of Leeds provides NHS Digital with the cryptographic salt (via SFT)
3. NHS Digital provides the University of Leeds with HES A&E, Inpatient and Outpatient data according to specified criteria with patients referenced by HESID (via SEFT)
4. NHS Digital provides TPP (ResearchOne) with a set of patient pseudonyms (via SEFT).
5. TPP (ResearchOne) provides University of Leeds with primary care data for patients identified from the set of patient pseudonyms supplied by NHS Digital with patients referenced by ROID (via SEFT).
6. TPP (ResearchOne) provides NHS Digital with a mapping from each patient pseudonym to a unique ROID (via SEFT)
7. NHS Digital provides University of Leeds with a mapping file that maps a unique HESID to a unique ROID identifier (via SEFT)
The data which will be accessed by the University of Leeds will be pseudonymised they will have no access to identifiers. They are not permitted to use to data provided to try and re-identify any individual.
ResearchOne has been separated out in the data flow diagram and the summary above to TPP (ResearchOne) and TPP (SystmOne). Project documentation refers only to ResearchOne to emphasise that the project will use only data from the ResearchOne database. The Phoenix Partnership (TPP) are responsible for SystmOne, ResearchOne, and for ensuring the necessary separation of duties for staff working on SystmOne and ResearchOne. We leave it to NHSD to liaise with TPP regarding the data flows between the two parties, and how these data flows can be performed via SEFT in a manner
that is consistent with the necessary separation of duties. The ResearchOne database is stored and processed inside the data centres which host the SystmOne production environment. It is not possible to disclose the location of these data centres due to governance requirements but they are Tier 3 data centres that have been accredited by the NHS for storing and processing clinical data. There is a disaster recovery
site (hosted to exactly the same standards as the live site) which is used as a back-up location in the event of any failures at the main site. Documentation relating to ResearchOne can be found at:
http://www.researchone.org/documentation/.
University of Leeds generates and supplies a salt key that is used in the generation of pseudonyms by NHSD and TPP (SystmOne). Further details regarding the pseudonym generation process are provided in the "LPMAESTRO - WS2P1 - Pseudonym Generation Process.pdf" evidence document associated with this application. To ensure that the identifier used to generate the pseudonyms (NHS number) cannot be recovered by the University of Leeds, the University of Leeds does not receive any pseudonyms generated
using the supplied salt key. The University of Leeds receives the following: i) HES data referenced by a HES ID, ii) ResearchOne data referenced by a RO ID, and iii) a mapping file from HES ID to RO ID. The linkage methodology has been developed so that the
University of Leeds is responsible for the generation and supply of the salt key, and subsequent data flows to the University of Leeds do not contain any data that could be re-identified by the knowledge of the salt key. Additionally, the salt key is used only a one-time basis, such that any pseudonyms generated cannot be matched across data sets obtained for different usages. Approvals for the project (including NHS Ethics)
have been obtained on the basis of the proposed linkage methodology.
NHS Digital will identify patients based on the presence of an A&E attendance or Inpatient episode (Index Episode) at one of the 8 included hospitals within the defined index period (1st April 2013 – 31st March 2014), A&E attendances, Inpatient admissions and Outpatient appointments will be obtained from Hospital Episode Statistics (HES) for the period from 1st April 2012 - 31st March 2015 (i.e. 1 year prior to the index period, the index period itself and 1 year following the index period). This data will be provided directly to the University of Leeds with patients uniquely referenced by a unique HESID. Additionally, NHS Digital will generate a pseudonym for each included patient, according to the methodology described above, and supply this list of pseudonyms to TPP (ResearchOne).
TPP will generate pseudonyms for all patients in the ResearchOne database by applying the same methodology as NHS Digital and using the salt key supplied to TPP (SystmOne). TPP (ResearchOne) will then determine those patients whose pseudonyms are present in the list provided by NHS Digital. Selected primary care data will be extracted from ResearchOne for these patients for the period prior to and including
31st March 2015.
Primary care data will only be obtained where:
- the GP practice to which the patient is registered using TPP's SystmOne clinical information system and
- has opted-in to ResearchOne (and the patient has not individually opted-out).
TPP (ResearchOne) will provide primary care data directly to University of Leeds. Each patient will be uniquely referenceable in this data using a unique ROID. No pseudonyms will be included in the data provided by ResearchOne to the University of Leeds. TPP (ResearchOne) will also provide NHS Digital with a file that maps each pseudonym present in the list provided by NHS Digital and in the ResearchOne database to its corresponding ROID. NHS Digital will use the mapping file provided by TPP (ResearchOne) to map the HESID of each patient in the HES data to the ROID identifier of each patient in the ResearchOne data. NHS Digital will supply the resulting mapping file to the University of Leeds who will use it to match the data for a particular patient in HES data to the data for that patient in the RO data (and vice-versa).
Based on the HES data and ResearchOne data, patients with admissions to these hospitals (without an LP service) will be matched to referred and non-referred cases from hospitals with an LP service, either by matching for co-variates or by propensity scoring will be determined and implemented. As described in Section 5a (Objective for Processing), WS2P2 of the LP-MAESTRO project will focus on the linkage and
supply of data for patients attending hospitals with an LP service. Application and approvals for WS2P2 will be undertaken separately. Relevant variables for matching will include demographic (e.g. age, carer support, Index of Multiple Deprivation (IMD) calculated from postcode) clinical (e.g. diagnosis, long-term medication)
and health service utilisation (e.g. inpatient days, GP visits, major procedures, A&E/ED visits, and Medical and Surgical outpatient appointments). One of the novelties of this approach is the use of these characteristics identified from HES and from the primary care database to tackle the utilisation in the financial year before referral, as a way of ensuring that outcomes in the financial year after referral are not attributable
to easily identifiable pre-existing characteristics (case complexity) that are confounded with likelihood of referral.
Analysis will use the linked dataset and will estimate a standard regression model for estimating the relation between health care utilisation and key variables capturing the configuration of liaison services. The dependent variable in this model is therefore cost of health care utilisation derived from factors such as inpatient days, readmission rates, Emergency Department attendances and General Practitioner visits. The variables that will be used as determining factors relate to the configuration of liaison services, sourced from the data collected in WS1. The quantum of the liaison service provision will be captured by WS1 data related to structure and process e.g. staffing levels and contact time after referral. The standard regression approach rather than frontier-based approaches will be used as the focus is on how the explanatory variables impact
on the dependent variable, secondary care utilisation, rather than on the efficiency of certain providers.
All persons accessing the record level data provided by NHS Digital under this agreement are substantive employees of University of Leeds.
University of Leeds will not link the data further and the only data linkages are those permitted under this application / Data Sharing Agreement.

Objectives:
Improving the safety and continuity of medicines management at care transitions (ISCOMAT) is a series of interlinked work packages delivered by a multidisciplinary research collaboration between the Bradford Teaching Hospitals NHS Trust (BHTH) (as NHS lead and sponsor), the University of Bradford and University of Leeds. Each work package has designated lead(s) and is supported by researchers and collaborators from each of the organisations. BTHT has overall responsibility for the delivery of the programme and delegates responsibilities to the University of Bradford and the University of Leeds in a collaborator agreement. University of Bradford are not receiving any data as part of this application.
The programme is a series of interlinked projects which will design and test a complex intervention (a Medicines at Transitions Toolkit) to make best use of medicines and reduce harm through effective medicines management for heart failure patients from hospital discharge and into primary care.
When a patient moves between care settings (e.g. from hospital to home) medicine problems are common and planned changes are not always followed through. Patients particularly at risk are those with long-term illnesses taking several medicines – especially when medicines have been started or changed in hospital.
Patients with heart failure are the focus of our study as they are a public health and NHS priority, are frequent service users (including readmission to hospital), and susceptible to poorly managed medicines. Heart failure is responsible for approximately 5% of medical admissions and the hospital readmission rate within 3 months of discharge has been estimated as being as high as 50%.
ISCOMAT aims to help the way patients are supported with their medicines. This may contribute to improving their health through helping them better understand their medicines. It also aims to improve the way medical professionals work together to offer good standards of care to patients when they leave hospital. The specific objectives are listed below:
1. Map and evaluate current medicines management pathways across care transitions, describe the core characteristics of best practice and effective systems at each stage and compare with published evidence.(work package 1a)
2. Devise an underlying data linkage and data collection exercise to measure the effect of the proposed intervention (work package 1b)
3. Synthesise these data to develop a model of best practice that can contribute to a multi-disciplinary intervention (work package 2)
4. Based on a co-design process, integrate a patient-led perspective on the continuity and safety of the medicines management across care transitions to enhance the patient information-giving process as part of a Medicines at Transitions Toolkit (MaTT) intervention (work package 2)
5. Assess the intervention for usability and acceptability, establish an effective implementation process, and determine the feasibility of data collection for economic evaluation (work package 3)
6. Evaluate the effect and cost effectiveness of the intervention in a multi-centre cluster RCT (cRCT), in conjunction with a rigorous process evaluation. (work package 5)
This agreement will facilitate objective 2 (data-linkage) which is a data linkage feasibility study and will construct the data linkage foundations for the cluster RCT (objective 6). A future application will be made to access data for objective 6 (multi-centre cluster RCT). The day-to-day running of WP1a and WP1b is the responsibility of the programme manager employed by the University of Bradford. This includes co-coordinating the development of the research protocol, ethics submission and the identification of sites to identify, consent and recruit participants. The lead investigator for this work package 1 is based at the University of Leeds and the data linkage will be transferred, processed and analysed by researchers at the CTRU, University of Leeds.
The data linkage feasibility study has recruited in the region of 55 patients from four hospitals who were consented and recruited at the point of discharge from an in-hospital stay for heart failure by a research nurse. The hospitals are Castle Hill Hospital in Hull, Leeds General Infirmary, Calderdale Royal Hospital and Royal Blackburn Hospital. The consent process included consent for information about their health conditions and prescribed medicines held by their hospital and GP to be accessed via the organisations (i.e. Data Providers) which hold this information, for example, NHS Digital, SystmOne, EMIS and the National Health Failure Audit (NICOR), along with community pharmacies. Data will be received, processed, stored and analysed by the by the Clinical Trials Research Unit (CTRU) at the University of Leeds. No patient level data will flow to the Bradford Teaching Hospitals NHS Trust from the CTRU.
Upon recruitment from four different hospitals the research nurse (or study research fellow) registered the patient with the CTRU and provided demographic details. Details about the patients study eligibility, admission and discharge medication were also be recorded. Registration was via a secure online database at the CTRU. The data recorded at registration will include patient’s name, date of birth, gender, NHS number and patient study ID.
The study team have mapped the data variables available from each data provider onto the primary and secondary endpoints of the proposed definitive cRCT (objective 6) to allow for an accurate assessment of the patient pathway and important co-morbidities.
The primary endpoint for the definitive trial will be all-cause mortality + HF rehospitalisation measured over 12 months from hospital discharge. We anticipate that the data required for this outcome will be obtained from HES and ONS.
The key secondary endpoint is the number of patients prescribed the correct heart failure medications at 12 months post-discharge. The study anticipate that the data required for this outcome will be from NICOR, primary care and community outpatient pharmacy databases. Clinical and prognostic data such as diagnosis, comorbidities and discharge information, will be collected from the HES, NICOR, and primary care databases.
The findings of this data linkage study work package will inform the data variables required for the definitive cRCT and it is anticipated that a reduced dataset will be required for the subsequent DARS application for the cRCT.
The CTRU statisticians will provide patient identifiers in line with the requirements of HES analysis Guide Requirements. This may include patients name, date of birth, gender, NHS number and patient study ID. The patient identifiers will be sent to NHS Digital for confirmation that there is a record for the patient in HES / ONS. NHS Digital will provide data extract to the CTRU.
The above process will be performed with each of the Data Providers. The identifiers required to accurately identify a study participants will be agreed with each provider as part of the application process, ensuring the minimum identifiers are used. The CTRU statisticians will link the individual patient data items from each of the data providers to allow for the creation of a master patient file.
Yielded Benefits:
Delays have occurred in the access of data from other data sources (e.g. NICOR) and the organisation have been unable to receive data direct from the primary care providers. It is anticipated that the data linkage pipeline work will complete by the end of 2020, and will be based on data obtained directly from NHS Digital only.
Expected Benefits:
The benefit of this data linkage work is that it will allow the study to understand how linked data can be used to explore the intended and unintended outcomes of a transfer of care for people with heart failure.
By using this pilot stage to join the data of a small number of patients the study can explore whether their hospital discharge has been followed by a readmission or death and to explore how multi-disciplinary and multi-organisational care works to safely continue NICE-recommended medicines sets after people leave hospital.
This work will allow the study to develop the capacity to understand how this linked data can be used to measure important outcomes so that they can evaluate a co-designed intervention that improves patient care across a care transfer. The results of the data linkage work are expected to inform the evaluation methods used in the definitive cRCT integrated care (Domain 4.9). The continuing drive for cost effectiveness is explicitly recognised through the studies accompanying and comprehensive economic evaluation. Furthermore, the studies discussions with health service commissioners have highlighted the need for evidence to support future commissioning of community pharmacy services as well as the need for more effective optimisation of heart failure treatment, with associated health benefits.
The overall aim of the research has the potential to reduce the burden of cardiovascular disease by reducing preventable cardiovascular events that occur in the period after patients with heart failure are discharged from hospital through a combination of diminished medication errors and health gains from optimised treatment. Furthermore, the findings and other envisaged outputs may make a valuable contribution to the medicines management of many other NHS patients with long-term conditions.
Outputs:
The study team expect to have a data linkage algorithm in by the end of 2017. The plan is to publish this work in peer-reviewed journals (for example Health informatics, target submission 2018) and present at relevant conferences to inform the wider research community on the lessons learned in data linkages (for example, 'Using electronic health records in clinical trials: rising to the challenge of developing a data linkage pipeline – experience from the ISCOMAT programme' was presented as an at the joint International Clinical Trials Methodology Conference / Society for Clinical Trials 2017 conference in Liverpool on May 7-10, 2017).
The study will inform participants and involved clinicians and hospital teams and update the trial website to share the study findings in various formats (e.g. lay summaries).
All outputs will contain only data that is aggregated with small numbers suppressed in line with the HES Analysis Guide.
Processing:
CTRU have receive patient identifiable data (including patient’s name, date of birth, gender, NHS number and patient study ID data) for each consenting participant from the participating site. The total number recruited is 53 participants. This data is processed by the trial data manager and statistician at the CTRU at the University of Leeds.
The trial statistician will provide NHS Digital with study ID, NHS number and date of birth for linkage to HES / ONS. The NHS Digital will provide the linkage to HES APC, OP, A&E, CC and ONS for each study participant.
All transfer of data between the CTRU trial statistician and the NHS Digital will take place via a secure file transfer system / secure data depot as agreed between the data provider and the data recipient.
Upon receipt of the data, data cleaning will be undertaken by CTRU statistician in internal process. This will include processes to ensure no duplicate episodes, no admission after date of death (if deceased). Additional data cleaning, analysis and linkage across each dataset will be in accordance with a Statistical Analysis Plan.
This CTRU trial statistician will subsequently link the HES / ONS record level data to participant record level data from primary care clinical systems (SystmOne and EMIS), a national cardiovascular specialist registry (National Institute of Cardiovascular Outcomes Research) and community pharmacy data. Data will also be linked to the ISCOMAT dataset held at the CTRU (consisting of the patient identifiers and details of patient’s study eligibility, admission and discharge medications). This will enable a data linkage pathway algorithm to be developed. The algorithm will not identify at the individual participants, the outputs will identify the variables and pathway.
The data items linked between the datasets are those relevant to the primary and secondary analysis of the proposed cRCT have been identified in each provider dataset. The data linked by the CTRU across the databases will establish quality and completeness of the data available from each database and derive the most reliable data pathway for the trial. The same patient identifiers will be used across each dataset, if permitted by the provider, to ascertain information on the same patient is collected.
For this data linkage feasibility study, work will be undertaken to provide descriptive statistics which show the extent to which linkage was successful for each data source. No statistical modelling will be attempted. The study will summarise the extent to which can successfully obtain the primary and secondary outcomes of the cRCT. The CTRU statistician will also summarise the covariates that plan to adjust for in the analysis of the subsequent cRCT. These covariates will be pooled from all the data sources. Levels of missing data from each data source will be summarised to demonstrate the acceptability of the data sources for the cRCT. It is anticipated that the study will be able to triangulate data from the various sources to produce a master patient record. The agreement/disagreement between various data sources on common data items will be reported.
All individuals with access to the data are employed by the CTRU, University of Leeds and will have undergone CTRU Data Protection training prior to accessing the data. No other third party will have access to the data. Data will not be used for any other purposes: it will not be used for commercial purposes, nor for direct marketing purposes. The University of Leeds is the sole data processor.
IT Infrastructure: The CTRU server infrastructure is split between two data centres on the main University of Leeds campus. Backups taken from this infrastructure are replicated to the University of Leeds disaster recovery site at the University of York with tape backups being kept at Iron Mountain. In all locations data is stored encrypted on disk/ tape. The 2 disaster recovery sites provide different recovery options. The site at University of York is a warm online copy on disk that can be retrieved instantly for the last 30 days. The Iron Mountain site holds a cold offline copy on tape for 12 months.
At the University of York location, the server is University of Leeds own equipment and connects only to the University of Leeds network. No individual at the University of York can access the data. The University of York only provides the physical space and power to support this.
University of Bradford are not part of the agreement and will not be accessing any data through this application.
ONS Terms and conditions will be adhered to.
All organisations party to this agreement must comply with the Data Sharing Framework Contract requirements, including those regarding the use (and purposes of that use) by “Personnel” (as defined within the Data Sharing Framework Contract ie: employees, agents and contractors of the Data Recipient who may have access to that data).

Objectives:
The University of Leeds are running a project called QuantiCode. This project is funded by the Engineering and Physical Sciences Research Council (EPSRC) from March 2016 to February 2019 (details: http://gtr.rcuk.ac.uk/projects?ref=EP%2FN013980%2F1). The overall QuantiCode project is divided into 3 stages:
1) Data fusion, covering tools for data linkage and visualizing data quality, and thought leadership in data governance.
2) Analytical techniques that allow users to interactively mine longitudinal data for patterns.
3) Governance-aware abstraction techniques that allow users to explore how complex data may (or may not) be simplified to reveal important patterns.
The work will be evaluated by the collaborating organisations to ensure that the solutions are applicable in the real world.
The QuantiCode project involves a number of collaborating organisations (University of Leeds, Bradford Teaching Hospitals NHS Foundation Trust, Consumerdata Limited, NHS Digital, Sainsbury’s Supermarket Limited, Leeds City Council, Leeds North Clinical Commissioning Group, AQ Limited), who are interested in this work and are supplying datasets and will receive reports and tools as outputs of the project. NHS Digital is one of these organisations, as NHS Digital has a number of very large datasets, and Data Quality is an issue which is particularly important – it impacts directly on areas such as running the NHS (invoice validation, etc.), as well as some indirect benefits (research and analysis to develop policy/clinical guidelines). By collaborating with the QuantiCode project, it is expected that there will be benefits for NHS Digital and benefits to healthcare more widely as a result.
Any data provided from NHS Digital to the University of Leeds for this project will not be linked in any way with the other datasets being used. No record-level data from NHS Digital will be shared, or be in any way accessible, to third party organisations (including the other collaborating organisations). Similarly, no aggregated data including small numbers (as defined in the HES Analysis Guide) may be shared with (or be in any way accessible to) third party organisations
Within the bounds of the QuantiCode project, the purpose for processing healthcare data from NHS Digital is to allow different designs of visualisation and machine learning technique to be compared for their ability to meet user requirements, and allow the QuantiCode data analysis tool to be tested prior to release to NHS Digital for in-depth evaluation. A single year of HES Admitted Patient Care data is being requested in order to fulfil these objectives. The single year of hospital data is important as there are data quality process which take place at the end of the year, meaning that a sub-set of data (e.g. 6 months)will display different characteristics to the finalised (“Annual Refresh”) data produced after the end of the financial year. Without healthcare data, it is possible that the methodologies/tools cannot be applied to healthcare data, and the opportunity to improve the healthcare data will be lost.
In addition, a specific purpose for processing the health data is to make a detailed analysis of patterns of “missingness” in data (the manner in which data are missing from a sample of a population). The goal is to be able to investigate patterns that involve: (a) several (3+) variables missing together, and/or (b) are dependent on the particular value of other variables (e.g., provider code and admission type). These patterns are currently unknown and such missingness may involve any variable in a dataset, which is why all variables (except those deemed sensitive or identifiable) have been requested.
Expected Benefits:
It is expected that there will be benefit to health from the outputs provided to NHS Digital. The benefits will occur as benefits to the health system, either directly (through improvements to data collections) or indirectly (better quality data used in analysis/research).
The following headline benefits will arise from NHS Digital’s usage of the tool:
1) Allow NHS Digital to conduct integrity checking to identify occurrences of poor data quality in routinely collected data, for feedback to data providers (target date 30/9/18).
2) Allow NHS Digital to cross-reference variations in data quality issues with external influences (e.g. change in policy, change in priorities, change in resource, change in service provision or structure, coding improvement initiatives) (target date 30/4/19).
3) Allow NHS Digital to conduct bias checking to identify occurrences of poor data quality in routinely collected data, for feedback to data providers (target date 30/9/19).
4) Support NHS Digital in the development of new business rules for automated data profiling and feedback to data providers (target date 30/11/20).
5) Improve NHS Digital’s understandings of biases across time, geography and activity; NHS Digital’s focus has necessarily been on data quality by provider (in order to report back to providers so that data quality issues can be addressed ), with less emphasis given to time, geography and activity.
6) Allow NHS Digital to quantify the impact of data quality issues - e.g., whether the degree of missingness for certain conditions supports linkage match rates.
7) Improve the quality of the data used by NHS Digital when conducting analysis.
8) Improve the quality of the data provided by NHS Digital to third parties when conducting research/analysis.
NHS Digital manages many of the nation’s critical health and care data assets. It collects data from a range of care providers and provides secure and controlled access to those data by legally authorised bodies. Better use of health and care data will help those involved to:
- manage the system more effectively;
- commission better services;
- understand health and care trends in more detail;
- develop new treatments; and
- monitor the safety and effectiveness of care providers.
Understanding the quality of data is essential in deciding whether it is fit for these uses. The benefits above will help NHS Digital develop appropriate methods to monitor, challenge and highlight data quality issues to various audiences, giving the them the ability to correct the data if submitting or adjust their findings accordingly if just analysing.
NHS Digital also has a statutory responsibility, enacted in the Health and Social Care Act 2012 (section 266), to assess the quality of the data it receives against nationally published standards and to publish the results of those assessments. These benefits are likely to lead to new measurements in the report covering this statutory responsibility.
The tools and methodologies developed through the QuantiCode project may also benefit other organisations in other sectors, but the data from NHS Digital is only disseminated on the basis of there being a benefit to health.
Outputs:
The intended outputs relating to health are:
1) Data analysis tool Version 1 (target date 28/2/18). This output will be a visual analytics tool, which allows users to gain an overview of missing data patterns and investigate data integrity in health datasets.
2) Research report 1 (target date 30/9/18). This report will describe the application of the tool to health data, and the benefits that the tool provides. The report will be submitted to a high-impact outlet such as the Journal of the American Medical Informatics Association (the pre-eminent journal for research into methods for analysing health data).
3) Data analysis tool Version 2 (target date 31/5/19). This version of the visual analytics tool will allow users to investigate bias caused by data quality issues in health datasets.
4) Research report 2 (target date 30/11/19). This report will describe the application of the tool for bias investigations, and the benefits that the tool provides. The report will be submitted to the Journal of the American Medical Informatics Association.
Outputs 1 & 3 will not contain any data – a user will load their dataset into the tool to analyse missingness. Outputs 2 & 4 will contain only aggregate level data with small numbers suppressed in line with HES analysis guide. That data will be shown in figures that illustrate the usage of the tool.
The ultimate beneficiaries of this work will be the general public. For example, CCGs and local authorities analyse data to generate business intelligence for operations and investment, with the aim of providing us all with improved and more cost-effective services. Businesses similarly require business intelligence for operations and investment, which translates to jobs and other economic benefits. To bridge the gap between these indirect benefits from the project and popular interest in big data, the University of Leeds will conduct a range of public engagement activities which include live demonstrations at the annual Leeds Festival of Science, a short film, an on-line tutorial about the ethics surrounding data analytics, and publishing articles in the popular scientific press.
Processing:
The dataset (to be) provided by NHS Digital consists of pseudonymised, record-level data. The dataset will be transferred by the University of Leeds’ Integrated Research Campus (IRC) Data Services Team using NHS Digitals Secure Electronic File Transfer system (SEFT) The data will only be accessed by substantive employees of the University who are contributing to the project.
The patient data from NHS Digital will not be linked with any other dataset.
The Quanticode project will develop tools and methodologies for investigating data quality across a number of datasets. The aim is to test these tools and methodologies across a variety of datasets, including health data. Although the QuantiCode project as a whole will examine issues around data linkage, that work will not involve the use of data from NHS Digital data.
The QuantiCode project will process datasets provided by other organisations involved in the project, and the methodologies/tools will be developed to apply across datasets as much as possible. One of the aims of this is to ensure that techniques are developed which are generically applicable, rather than each sector needing to develop their own tools.
The NHS Digital dataset will be used to help design and test a new data analysis tool, which allows users to investigate data quality in health records. The development process for the tool will involve: (a) characterising the dataset so that scalable algorithms and appropriate statistical models may be designed, (b) using the dataset as an exemplar to design and implement new interactive visualization techniques for data quality investigation, (c) running the data to refine the statistical models, and (d) testing of the data analysis tool prior to release to NHS Digital for in-depth evaluation.
The NHS Digital dataset will only be used where necessary for the purposes in this agreement. Live data will not be used for early stages of development/testing when it would be more appropriate to use test data.
The data from NHS Digital may only be processed in order to produce the outputs detailed below (in the Specific Outputs Expected section).

Objectives:
The University of Leeds primary aim is to assess the feasibility and reliability of routinely collected data on health resource use.
Residents of care homes are amongst the frailest in our population with significant health and social care needs. The health requirements of residents place considerable burden on the NHS, in primary and secondary care. Greater demands are placed on the workload of GPs providing care for care home residents than caring for people in their own homes, in face to face contacts and out of hours visits. Care home residents are significantly more likely to attend emergency departments by ambulance and be admitted to hospital compared to the older population generally.
Hospital admission exposes residents to risk of hospital acquired infections and falls and is disruptive for this frail population as they struggle to return to their previous health state once discharged. If not appropriately addressed, the burden on NHS primary and secondary care services will continue to rise for this expanding client group.
Promotion of health of frail older people in care homes is poorly and inconsistently developed. Despite the potential for reduced NHS expenditure from improved health, provision of programmes to support activity within UK nursing homes (which could promote health and well-being) is only patchily realised. Only 10% of care home residents receive physiotherapy, and just 3% occupational therapy.
The feasibility trial proposed by The University of Leeds is the final stage of a programme grant funded by the National Institute of Health Research (NIHR). The programme grant has been divided into 5 work streams, with earlier work involving observation of care home environments; interviews with care home staff, residents and relatives to explore how to best implement change in activity; assessing which questionnaires to use and how to best measure activity levels; and developing an appropriate intervention with the aim of increasing activity (or reducing sedentary behaviour) in care homes.
This trial is now testing the intervention in 6 of 12 homes from selected locations within Yorkshire, randomised on a 1:1 basis to receive the REACH intervention plus usual care, or to continue with usual care only. It is anticipated that 8 - 12 residents will be recruited from each of these care homes. Staff working in care homes randomised to receive the REACH intervention will implement the intervention in their care home. Staff working in care homes randomised to the control arm will continue with their usual routine care to residents.
All 12 homes will provide data for the trial, either directly in person, from care home records, or via routine data sources such as NHS Digital. Part of the trial aim is to look at the best method of obtaining both safety (i.e. hospital attendance) and health resource use data. If the University of Leeds are able to do this by collecting HES and other data sets this will inform how data is obtained ultimately to run a large scale trial in many homes. This would happen if The University of Leeds feasibility trial was successful.
The University of Leeds will seek to establish the number of admissions overall from the 12 participating care homes and assess the completeness of this data. This aggregate data will allow assessment of the effect of the intervention at a whole home level, rather than only being reported for consenting residents (a sub-set of the care home population). This will allow us to assess whether the consenting cohort is representative of the whole home or whether there are differences in the number of hospital attendances and admissions for those who are and are not taking part in the research.
Expected Benefits:
A) For the identifiable, consenting cohort benefits include:
• Obtaining reliable ‘safety’ information – i.e. data which will show the reasons for and number of hospital attendances or admissions. This is important to be sure there are no adverse impacts of the intervention. It could also give us an indicator that the new intervention might have some benefits if people from intervention homes attend hospital less.
• Obtaining health resource use information – e.g. the number, type and length of hospital admissions - is a key element of NIHR-funded research. It is important to have this ‘health economic’ data which details the full cost of an intervention – for example, an intervention may appear to be effective, but incur many additional NHS costs such as multiple hospital visits or GP call outs. Without collecting data on health service use we cannot undertake this analysis. Collecting hospital attendance data from HSCIC for the feasibility study will inform how to best undertake this for the main trial, as well as giving an early indicator of resource use.
B) For the aggregate, non-identifiable cohort benefits include:
• An overview of safety at the whole home level. This will help us see the overall safety of the intervention – so we would be able to observe any differences in hospital attendances between ‘intervention’ homes and usual care homes. This would contribute to our decision to proceed with a main trial – i.e. if there are no safety concerns we would be happy to proceed.
• Having hospital attendance data for all (or at least ‘most’) residents gives a more representative picture of health resource use, rather than just that used by recruited (consenting) residents. For example it might be that those who consented are less ill than those who didn’t, so we wouldn’t get a true picture of ‘whole home’ hospital admissions from consenting residents alone. It is an important benefit to be able to report the generalisability of research findings – this data would help us to do that.
Decreasing mobility and increasing dependency have many adverse effects. For residents in care homes, it may lead to increased incidence of pressure sores, contractures, cardio-vascular deconditioning, urinary infections, and loss of independence. Mobility problems and reduced physical activity compound health difficulties by directly affecting physical and psychological health and reducing opportunities to participate in social activities; social isolation negatively impacts on mood and self-esteem, which can then further adversely affect physical health. Residents identify mobility as of central importance to quality of life and well-being and residents with dementia wish for more day-time activities. Physical ill-health and disability are the most consistent risk factors for depression in later life with reports suggesting that, rather than illness per se, it is the resulting functional limitations (handicap) including social participation and meaningful relationships that increase risk of depression. Physical activity provides positive benefits for older people > 65 years for a range of outcomes: decreased disease risk, mood and overall health. For frail institutionalised older people, systematic reviews indicate that physical training can positively affect fitness for some participants; the level of effect may be related to level of frailty. A recent review of the effects of physical activity for older people with dementia (not all of whom were in institutions) reports some benefits for physical function.
Additional benefits may be accrued through enhancing social engagement directly by, for example, participation in communal activities such as exercise sessions, and indirectly by maintaining physical abilities sufficient for the resident to be mobile enough to move around the home and interact with other residents. Such social engagement has been shown to be linked with more successful ageing.
The University of Leeds proposed research to enhance routine physical activity supports the aims of the DH report, NICE guidance and BGS6 reports to promote the well-being of older people in long-term care. It is in keeping with the National Care Home Review, which promotes the concept of care homes as community places with emphasis on creating opportunities for meaningful activity, for shared decision making and for building an environment that supports community.
The outputs will inform feasibility assessment in relation to a larger definitive clinical trial which would assess incremental cost effectiveness of an intervention to increase physical activity in care homes, compared to usual care. This feasibility assessment will be complete by the end of the current NIHR programme grant (14 February 2018).
Outputs:
The University of Leeds will begin the staged process of developing a complex intervention embedded in the routine of care homes to promote physical activity tailored to the context and environment of individual care homes and thereby enhance quality of life for this neglected group.
Ultimately, and if successful, the intervention strategies will be disseminated through the local Care Home Forum, local and national contacts with Adult Social Care and links with national care home providers through co-applicants and the Steering Group.
Successful completion of the feasibility trial (the last stage of the programme grant) will inform the application for funding to undertake a definitive Randomised Controlled Trial (as described in 'objective for processing'), to investigate the effectiveness of a physical activity intervention in care homes across England. The outputs will be used to establish a protocol for this trial (or otherwise, as appropriate).
The University of Leeds will report the results of the REACH trial to the NIHR (the funder) and, if the feasibility study results indicate that it is reasonable to proceed to a main trial, will apply for further NIHR funding to conduct a definitive main trial.
The feasibility assessment will be completed and published at the end of the programme grant (14 Feb 2018). Results for the trial will be presented in a report for the funding body NIHR. Academics will have access to the outputs via anonymised publication in journals. Indicators will not be produced that show the performance of organisations.
The outputs of this would inform best practice in care homes, and would be published in relevant academic journals (for example Age and Aging), non-academic platforms accessible to the general public (e.g. a study website), and would be disseminated to the care home community via relevant national and local forums or events.
Specifically the results of the feasibility study would be published in academic journals (e.g. Age and Aging, BMC Pilot and Feasibility Studies) and disseminated to the participating care home staff, residents and their relatives.
Outputs are expected in January 2018, when the study will complete analysis. Outputs will be disseminated as detailed above, regardless of the findings (and 'success') of the research.

Objectives:
The SHIFT (Self-Harm intervention Family Therapy) Trial has been designed as a pragmatic, individually-randomised, controlled trial comparing Family Therapy (FT) with Treatment as Usual (TAU) for adolescents aged 11 – 17 years who have engaged in at least one previous episode of self-harm. The trial aims to recruit 832 participants from centres in Yorkshire, Greater Manchester and London. Family therapy will be delivered by qualified family therapists using a modified version of the Leeds Family Therapy & Research Centre Systemic Family Therapy Manual (LFTRC Manual), the development of which was funded by the MRC to support trials of FT. The primary outcome is rate of repetition of self-harm leading to hospital attendance 18 months after randomisation. Secondary outcomes include rate of repetition at 12 months, cost-effectiveness, quality of life, and predictive/process measures.
Data will be processed alongside other data collected for SHIFT Trial participants to form the final data set for trial analysis. Specifically: HES APC & A&E data will inform the primary outcome of the trial (hospital attendance following self harm) and the safety profile of participants (hospital attendance for any reason); ONS mortality data will inform the safety and population profile; MHLDDS data will enable a fuller description in the trial results of, and accounting for, services accessed by participants. All publications and reports to external bodies utilising the data will be fully anonymised; participants will only be identifiable to the trial team (who are already in receipt of full identifiers by virtue of existing data provided by and for participants).
Data will not be shared with third parties.
Yielded Benefits:
- Publication of results (HTA monograph and academic publication) - Contributing to the evidence base to support commissioning of an individual patient data meta-analysis with the aim to identify subgroups of adolescents in whom a therapeutic intervention for self-harm shows some evidence of benefit in order to guide future primary research.
Expected Benefits:
The SHIFT Trial was commissioned by the Department of Health via their National Institute for Health Research (NIHR) funding stream.
The primary purpose of conducting research like this is to inform NHS practice. The trial design is such that the ‘primary outcome’ is hospital attendance following self-harm 18 months after trial entry – what this means is that the University of Leeds will compare hospital attendances for the group of young people who received family therapy and the group who received usual care. The University of Leeds can only make this statistical comparison when everyone in the trial has been involved for 18 months. This is now the case – the last participants completed follow up in June of this year, so statistical analysis is underway.
Once the data is analysed the University of Leeds will have the results showing whether or not family therapy was better than usual treatment. Whatever the outcome there will be some benefit to the NHS and to people using NHS services. A review of the NIHR report and other literature this will inform NICE guidance which in turn will influence NHS commissioning.
A positive outcome showing that family therapy is more effective than current usual care would influence NICE guidance for best practice within the NHS. This would be established after publication of the main results - in 2016/17.
If family therapy is shown to be no better than standard care, the results will provide other valuable insights which will assist commissioners. For example, it may be that family therapy is does not lead to a decreased number of hospital attendances however, the results will show whether it is more or less cost effective overall. If it is worse or better, this will be similarly disseminated to inform practice.
Outputs:
The primary and secondary analyses from the SHIFT trial will be published as an HTA monograph (SHIFT is funded by the Department of Health’s National Institute for Health Research (NIHR) Health Technology Assessment (HTA) programme. It is a key funder for a lot of large scale research projects across England. One of the requirements of conducting research funded by HTA is that a 50,000 word monograph (or report) is produced at the end of the study, providing detailed evidence of processes undertaken, trial results, interpretation and dissemination plans. The HTA monograph is due for submission March 2016, with an anticipated publication date of October 2016.
The findings will be submitted to relevant peer reviewed journals in the field of child and adolescent mental health and self-harm. There is the intention to more widely disseminate trial results to patient and public groups and to the lay community. The intention is to meet with a young person’s lay group in London (the same group they consulted regarding the newsletter) the National Institute for Health Research’s (NIHR) Young People’s Mental Health Advisory Group. At this forum the results will be presented and questions will be asked for their advice on interpretation from a lay perspective, and also their thoughts on where and how results would best be disseminated.
It is a condition of NIHR funded research that results are disseminated widely and appropriately and not just in academic journals – lay dissemination will be initiated at the meeting with the above group and their advice sought. The SHIFT trial will also look at other existing patient forums – local and national – for oral dissemination, as well as via charitable organisations (such as Young Minds) and local / national lay publications in which they might be able to include suitable articles.
In all cases this would be a summary of findings including the implications of these.
In summary results will be published in usual academic routes, papers in journals, presentations in conferences;
Newsletter to all participants (unless they have told us they don't want this) and to all participating staff;
Information on study web site;
Press releases and possible involvement of national media;
A special conference will be organised in Leeds for all the clinical colleagues who were involved.
The University of Leeds also want to do something with the young people and their families. Exactly what is still under discussion, consultation is still underway with YoungMinds and the NIHR CAMHS user group. This will influence wording of newsletters/ websites etc.
The intention, should the trial show that the intervention is effective, is that the results will ultimately inform NICE guidance and influence NHS practice in this area.
No outputs will ever identify any individual and be aggregated with small numbers suppressed, organisation, nor include any record level data.
Processing:
Data will be processed by the trial statisticians at the Clinical Trials Research Unit, Leeds Institute for Clinical Trials Research (LICTR) at the University of Leeds. It will be securely stored on CTRU systems with access only granted to the statistical team. Data will not be accessed by any third parties, nor will it be accessible across multiple organisations. LICTR has IG toolkit status (Code: ECC0010).
Identifiers will be sent to the HSCIC (Trial ID, postcode, NHS number, gender and Date of Birth). Data will be linked with existing SHIFT Trial datasets (data provided by participants and researchers in accordance with the REC-approved trial protocol and participant consent), as per the existing agreement with HSCIC that this data will augment the dataset with data that is difficult or impractical to obtain from individual NHS organisations. The linked data will be returned, containing identifiers, back to the University of Leeds and only accessed by a named statistician before it is stored in the networks.
Data will not be used for any other purposes: it will not be used for commercial purposes, nor for direct marketing purposes.
All individual accessing or processing the data are employees of the University of Leeds.

Objectives:
The objective for processing of these data is to perform research into survival following heart attack in England.
Over the last decade, there has been a substantial and sustained decline in mortality rates from cardiovascular disease in the UK. Despite this, cardiovascular disease remains the biggest killer in the UK and someone is admitted to an NHS hospital with a heart attack every three minutes. Moreover, improvements in acute myocardial infarction (AMI; heart attacks) survival are likely to be a major cause for the increasing incidence of heart failure (‘transferred morbidity’), which now affects around 900,000 individuals in the UK and accounts for 5% of all emergency hospitalisations. Presently, most patients with cardiovascular disease are elderly and because AMI survival has increased there are more patients living longer with co-morbidities. More frequently, such patients require specialist cardiovascular care in the form of invasive cardiac procedures including high and low voltage and resynchronization pacemakers and coronary revascularisation. Moreover, they frequently re-present to hospital – escalating the burden of admissions with heart failure.
Specifically, the research will aim to quantify the long term outcomes and hospitalisation rates for survivors of acute myocardial infarction in England.
The objectives of the analysis are:
1. To describe hospitalisation patterns and endpoints (heart failure, cerebrovascular disease, coronary revascularisation, vascular dementia, severe bleeding, acute myocardial infarction, atrial fibrillation, all-cause mortality) for patients hospitalised with non-fatal AMI (i.e. survivors of the index hospital stay) compared to those who have no recorded AMI .
2. To identify factors associated with hospitalisation and endpoints for hospital survivors of index AMI compared to those who have no recorded AMI specifically focusing on geographical variation and the provision of timely percutaneous coronary intervention.
In order to quantify the incidence of a range of hospitalisations (cerebrovascular disease for example) following survival from AMI, the study team at the University of Leeds need to ensure they have a clean cohort for analysis to minimise confounding where possible as well as data of the hospitalisations occurring among patients who have no recorded AMI. Detailed justification for the request of this level of data is outlined below.
1. Reasons for requiring hospitalisations amongst patients with no recorded AMI
In order to quantify the incidence of a range of hospitalisations (cerebrovascular disease, heart failure and other outcomes) following survival from AMI, the study team needs to compare the number of each hospitalisation type occurring amongst AMI patients to the number of each hospitalisation type which occur in the background population (in this case, the background population is the population of patients admitted to hospital without an AMI in the same study period). The hospitalisations occurring in the non-AMI population are used to determine the expected number of each hospitalisation type for someone hospitalised in the same year, and of the same age and sex as someone who has had AMI. The observed numbers of hospitalisations for those with AMI will then be compared to the expected number of hospitalisations amongst those without AMI to determine whether patients with AMI have more hospitalisations than expected (the excess hospitalisation incidence rate). Without this quantification of the excess hospitalisation incidence rate, the results will have no context as the study team will be unable to ascertain whether those with an AMI are more or less likely to experience certain conditions following their AMI than the background population. Determining this is the primary aim of the study.
The study team will require all hospitalisations amongst patients with no recorded AMI (subject to filtering described under “2. Ensuring derivation of a ‘clean’ cohort”) rather than a sample of hospitalisations. The study team considered the feasibility of selecting a reduced number of geographical areas to represent the nation rather than requesting national data but ruled out this approach because it would affect the validity of the findings. This is because an incidence rate is calculated from the observed hospitalisations amongst the AMI patients divided by the observed hospitalisations in the non-AMI population. A sample of hospitalisations (obtained from a reduced set of geographical areas) would change the study design from a population based cohort study to a case-control study, through which it is not possible to calculate incidence rates. Whilst it is possible to obtain relative risks from a case-control study, selecting a sample of ‘controls’ which are representative across a range of hospitalisations (i.e. all the study outcomes) in England could not be guaranteed. Without a representative cohort, the relative risks obtained would be prone to bias. Given the potential impact of the findings on healthcare users and NHS policy, it is essential to minimise uncertainty. In addition, a case-control study design is not suitable for studying multiple outcome measures as proposed by the study team. We would therefore be unable to achieve the study objective of defining the incidence of multiple hospitalisation outcomes following AMI if restricting the non-AMI patient data to a sample of the population, nor guarantee the validity of results which are obtainable under a case-control study design.
Finally, the study team aim to additionally determine the extent of geographical variation in hospitalisations and mortality following AMI, which require the calculation of incidence rates (and therefore require a full population denominator) for all areas in England.
2. Ensuring derivation of a ‘clean’ cohort
The study team cannot be sure that patients admitted to hospital with AMI in a given period of HES data have not had a previous AMI, or, whether they have had any of the conditions they are considering as outcomes, such as cerebrovascular disease prior to their AMI. Therefore, the study team proposes to derive the cohort for analysis from admissions from 2008/09 to present day, however, has requested for NHS digital to exclude all people from the data who have had a previous AMI or any of the hospitalisations the study team are considering as outcomes. The same filtering of prior conditions will be done by NHS digital for patients who have not had an AMI from 2008/09 onwards. This is a substantial minimisation effort by the study team, as without this step, data from 200-1/02 would have been required as part of the data application. Data from 2008/09 onwards will give sufficient data to look at time trends in hospitalisations and mortality as part of the analysis.
Details of all hospital attendances (not restricted to specific conditions with known associations with AMI) are required in order to understand the history of the patient and whether past (non-related) attendances have contributed in any way to that AMI attendance, or to any of the study outcomes including heart and non-heart related outcomes for patients in the AMI or non-AMI cohort. Post attendances also supports this (whether AMI contribute to non-heart related attendances).
Additionally, for each individual NHS Digital will provide a vital status indicator (alive/deceased) and, where individuals are deceased, the number of days between the data of admission and the date of death. The date of admission will not be supplied to the University of Leeds making it impossible for the study team to derive the date of death from the data supplied.
The research will be undertaken by the established Cardiovascular Epidemiology Research Group within the Leeds Institute of Cardiovascular and Metabolic Medicine at the University of Leeds. This research group has a remit of using large scale routine data and clinical registries alongside advanced analytical epidemiological techniques to better understand and improve the quality of care of patients with cardiovascular disease. The proposed work to study the hospitalisation patterns and outcomes for patients with acute myocardial infarction is part of a larger programme of work funded by the British Heart Foundation (Project Grant PG/13/81/30474) in order to fill an important knowledge gap of the long term hospital burden and non-fatal outcomes for patients with AMI using contemporary, large scale and national observational data.
Expected Benefits:
This study will quantify the burden of hospitalisations and long term outcomes for patients who are admitted to NHS hospitals and surviving acute myocardial infarction (AMI) in England. The research outputs as described will be disseminated widely to University of Leeds' established informal networks including the academic community, clinicians, patients and the public as well as NHS commissioners via the formal networks discussed in section 5c. Dissemination of the factors which could lead to increased hospitalisations and mortality to clinicians (via academic publications, presentations at clinical conferences and dissemination via the British Cardiac Society and British Heart Foundation) is envisaged to be a driver for improved patient care and has far reaching clinical and social benefits as outlined below.
Quantifying the burden of hospitalisations and long term outcomes for patients surviving AMI in England will for the first time, on a national scale, provide NHS commissioners with the necessary evidence to plan effectively for service provision and resource allocation for the large proportion of patients who now survive their AMI. Although improvements in treatment have resulted in improved survival rates for patients with AMI – the long term health burden of patients following their AMI is not yet known – and this is what the study team propose to determine. In addition, the findings from this study can be used to inform new endpoints for future clinical trials, to ensure that not only the mortality or short term cardiovascular outcomes of AMI patients are considered, but also longer term cardiovascular and non-cardiovascular outcomes in developing and testing new treatments in future.
In addition, by quantifying the impact of lack of adherence to guideline recommended care on re-hospitalisation and mortality or the impact of delayed PCI treatment on re-hospitalisation and mortality, the Cardiovascular Epidemiology research group would provide the scientific supporting evidence to clinicians to strive for improved adherence to guidelines, which therefore has the potential to improve outcomes for patients.
Increased patient awareness of the impact of AMI on future hospitalisation and mortality, through dissemination to the public as described, could not only lead to patients modifying their own health behaviours to minimise their own risks of future hospitalisation, but patient and public who are informed by this knowledge can also provide strong motivation for clinicians and commissioners to improve patient care and care pathways.
Knowledge of geographical variation in hospitalisation and mortality from AMI will identify key areas of inequality in the NHS, dissemination of this knowledge to NHS commissioners will enable them to act upon such inequalities to ultimately drive up standards and provide direct and measurable benefit to patients and the NHS. This work forms part of the wider research conducted by the University of Leeds' research team (Cardiovascular Epidemiology), and will therefore contribute to a growing body of evidence regarding the quality of care and outcomes for patients surviving AMI, whilst adding important new insights into the long term health burden for the increasing number of AMI survivors which focusses not only on mortality, but importantly, also on re-hospitalisation for a range of cardiovascular and non-cardiovascular conditions.
The Cardiovascular Epidemiology research group has expertise in health services research which directly impacts on patients, policies and healthcare professionals through research papers, the media and conferences. The research group has an excellent track record for translating research to clinical impact, which specific examples listed below:
Research referenced in NICE guidelines:
1) Clinical risk scoring for acute myocardial infarction referenced in NICE Clinical Guideline 94 (Gale CP et al, Heart, 2008; 95(3):221-227)
2) Atrial fibrillation research referenced in Atrial fibrillation: management, NICE clinical guideline 180 (Cowan, Long and Gale et al. Heart (2013): heartjnl-2012)
3) Pre-hospital ECG research referenced in European Resuscitation Council Guidelines for Resuscitation 2015 (Quinn, and Gale, et al. Heart (2014): heartjnl-2013).
Widespread media coverage and beyond:
1) Research by Dondo and Hall et al (Dondo T, Hall M, et al. Eur Heart J Acute Cardiovasc Care. 2016) has received widespread media coverage including radio and TV broadcasts as well as broadsheets and tabloids. This research also resulted in being invited to present at the Westminster health forum, and forms the critical evidence for the non-ST elevation myocardial infarction NICE Implementation Collaborative.
2) Research by Hall and Gale et al (JAMA 2016; Aug 30. doi: 10.1001/jama.2016.10766) as well as Wu, Hall and Gale et al (Eur Heart J Acute Cardiovasc Care 2016; Aug 29. pii: 2048872616661693) forms the evidence for the guidelines in practice NIC project (https://www.guidelinesinpractice.co.uk/nic-projects).
3) The geographic variation in AMI treatment by Dondo, Hall and Gale et al (BMJ Open 2016; 6 (7): e011600) has received widespread media coverage, and has led to a successful Department of Health / NHS England business case to develop the work further into a feedback quality improvement programme for patients, hospitals and commissioners (work currently ongoing).
Several members of the Cardiovascular Epidemiology research group have experience with Public & Patient Involvement, meeting patients to discuss a range of different research proposal and allowing them to influence and be part of the research agenda as well as disseminate research findings back to them, whilst some members of the research group hold very close involvement with the British Heart Foundation, especially their press office and policy group who therefore act as a powerful conduit for change and knowledge dissemination.
The research the Cardiovascular Epidemiology research group propose here is of direct and critical importance to the NHS and the Department of Health. Although heart attacks remain the biggest killer worldwide, survival rates are improving. As such, patients are living longer with their cardiovascular disease, and there are an estimated 7 million people living with cardiovascular disease in the UK. The Cardiovascular Epidemiology research group propose to look at the components of the disease process including the wide range of outcomes following acute myocardial infarctions so that the commissioners, hospitals and NHS England can make evidence informed policy decisions about the need for cardiovascular care, as well as where, when and in whom. The research group has an excellent track record to ensure this research outputs are far reaching with high impact.
Outputs:
Whilst the planned analyses will be disseminated to the academic and medical community in peer reviewed publications and presented at relevant conferences (see below), it is the clinical implications of the results for healthcare professionals, patients and regulators that are of greater virtue. It is clear that the results from the proposed study will help answer major gaps in the knowledge base of the health burden and ongoing hospitalisation for the increasing number of survivors following acute myocardial infarction which can therefore contribute to future healthcare policy. The Cardiovascular Epidemiology research team has established connections with numerous relevant groups through which findings will be disseminated to the NHS as well as patients.
These groups include: The NICE Indicator Advisory Group, the European Society of Cardiology Acute Cardiovascular Care Association, the European Society of Cardiology Acute Cardiovascular Care Association Quality of Care Group, the British Cardiovascular Society Guidelines and Practice Committee and the National Institute for Cardiovascular Outcomes Research (NICOR) Research Executive.
The Cardiovascular Epidemiology research group is led by an Associate Professor of Cardiovascular Health Sciences at the University of Leeds who is also a member of the above groups and is additionally an honorary consultant Cardiologist at York Teaching Hospitals NHS trust and secretary of the European Society of Cardiology Acute Cardiovascular Care Association – offering further dissemination routes which will be utilised.
NICE identifies awareness and knowledge as well as lack of motivation by healthcare professionals to be some of the key barriers to change in the NHS. Patients are at the heart of providing motivation for healthcare professionals to improve care in the NHS, therefore the Cardiovascular Epidemiology research group will focus on dissemination to patients as well through charities listed in point 3 below.
The Cardiovascular Epidemiology research group dissemination strategy will be as follows:
1). Peer-reviewed publication
Paper 1: Hospitalisation and mortality after acute myocardial infarction. Anticipated submission date: March 2018.
This paper will quantify the hospitalisations and long term outcomes for patients surviving acute myocardial infarction as well as determine the factors which lead to increased hospitalisation and morbidity.
Paper 2: Geographical variation in hospitalisation and mortality for patients surviving acute myocardial infarction. Anticipated submission date: August 2018.
This paper will quantify the potential geographical variation in hospitalisation for patients surviving AMI to identify potential healthcare inequalities for NHS Commissioners.
Paper 3: Hospitalisation and mortality for patients surviving acute myocardial infarction according to receipt of timely percutaneous coronary intervention (PCI). Anticipated submission date: August 2020.
This paper will specifically look at the association between timely receipt of PCI and the long term hospitalisations and outcomes for patients surviving AMI.
2). Wider academic dissemination of the research findings will also be made at major national and international conferences as appropriate, such as the British Society of Cardiology conference (June 2017/18/19) and the European Society of Cardiology Congress (August 2018/19/20).
3). Lay summaries of the research findings will be generated and disseminated to the following key stakeholders: the British Cardiovascular Society (BCS), British Heart Foundation (BHF), TakeHeart, NHS commissioners and clinicians/health professionals involved in managing heart attack. The Cardiovascular Epidemiology Research group have previously liaised with these organisations to ensure wide reaching research impact, beyond the academic community (see section 5d) In addition, the group website (Cardiovascular Epidemiology - https://medhealth.leeds.ac.uk/homepage/692/cardiovasucular_epidemiology-leeds_institute_of_cardiovascular_and_metabolic_medicine) as well as the research team's twitter account (@UoLCardioEpi) will be used to update the public, the network of stakeholders, charities, and health professionals throughout the project.
All outputs will be aggregated with small number suppression in line with the HES Analysis Guide.
Processing:
Data will be stored on the University of Leeds' Secure Electronic Environment for Data (SEED) system. The data will only be accessible to authorized individuals in the Cardiovascular Epidemiology Research Group within the Leeds Institute of Cardiovascular and Metabolic Medicine at the University of Leeds. The data will only be accessed by substantive employees of the University of Leeds and only used for the purpose of this project.
The data will be geocoded based on Lower Super Output Area (LSOA) to obtain information on higher aggregated geographical units (Clinical Commissioning Groups). No further linkage to the data will occur. Only summarised and aggregated data will be disseminated in the form of academic presentations and peer-reviewed journals.
The data will not be used for commercial purposes, provided in record level form to any third party or used for any direct marketing.
The study is funded by the British Heart Foundation. For the avoidance of doubt, the British Heart Foundation will not influence the results or dissemination of the research conducted, and the British Heart Foundation will have no role in the design, analysis or interpretation of the research.

Objectives:
Objective for processing: To conduct death checks, retrieve patient addresses and data verification (of the data included in the CVS sent to HSCIC) for the purposes of administering a PROM survey of men with prostate cancer.
** update December 2016 **
The original survey has been completed, and there has always been the intention to send a follow up survey 1 year after the first questionnaire to those men who consented to the first survey, to allow longitudinal assessment of outcomes.
Expected Benefits:
Clinical and scientific progress in managing prostate cancer will only bring benefits in terms of well-being and survival for patients if we develop comprehensive and clinically meaningful approaches to measuring the important patient outcomes.
Primary aims
• To describe the Health-Related Quality of Life (HRQL, e.g., physical, psychosocial) of men with prostate cancer using qualitative and quantitative methods;
• To explore if and how their HRQL is associated (cross-sectional) or is predicted by (longitudinal) disease, treatment and/or patient characteristics with a view to inform development of health care policy and service delivery in ways that better meet the needs of such men and their families;
• To describe the levels of patient empowerment and undertake preliminary exploration of the interaction between patient empowerment and HRQL.
Secondary aims
• To collect data to support, if possible, provider variation and health economic analyses especially for the longitudinal work;
• To analyse the questionnaire data collected by exploring and checking the psychometric properties (e.g., reliability, validity) of the newer, less well-established questionnaire measures and to investigate the possibility of developing an item-bank for HRQL assessment for use with men living with and beyond prostate cancer using Rasch models. Qualitative interviews will be used to identify ‘gaps’ in surveys of importance to patients and patient partners with a view to adding additional items/questionnaires in the second surveys.
• To explore the acceptability/options of electronic PROMs data collection in this cohort and acceptability of real time feedback to service providers to influence/support direct patient care.
The commercial aspect of this application does not, however, detract from the numerous and varied health-related benefits of the project, notably with regards to the insight into life with prostate cancer and intention to improve clinical treatment and policy going forward (see above). This work will ultimately inform clinicians and the NHS about prostate cancer sufferers and in turn help drive improvements to treatment. Picker Institute Europe is a health research charity, and this project supports the organisation's overarching objective to improve patient experience and healthcare.
** update December 2016 **
As data has only recently been received by the University of Leeds the benefits currently remain as above. With the follow up cohort, as NHS Digital will clean the data for patient objections which reduces the risk of sending the survey to men who have opted out under that model. The repeated fact of death check also reduces the risk of distressing the men's family by not contacting them if they are deceased.
Outputs:
The first output will be the survey itself. The applicant will send the PROMs questionnaire to prostate cancer patients in England, Scotland, Wales and Northern Ireland asking a variety of questions about their care and their quality of life. Those who respond will be sent a follow up questionnaires on an annual a year later asking the same questions. The target date for the first mailing is 5th October 2015, with the fieldwork continuing for three years.
Picker Institute Europe will present the research team at University of Leeds with a final data file once the fieldwork is complete from which the research team will carry out various analyses. This data file will consist of case data and will contain sampling information –, NHS trust and reference number - alongside the response data from the questionnaire. The mailing data will not be included in this submission, so names, addresses, year of birth and NHS numbers will not be present.
This data will contribute to a report presented to the funders: Prostate Cancer UK and the Movember foundation and a series of papers submitted to peer-reviewed journals. It is not yet known exactly what the articles will be on and where they will appear, but there is a large research team and it is hoped that there will be many outputs from this rich data source.
** update December 2016 **
The English Cohort part (Year 1) of the survey closed on 21st April 2016, with over 60% response rate. The Research Team in University of Leeds have received the final data file, so analysis is under way.
The next part of the Prostate Cancer project has already started. Mailings have been sent out for all Devolved Nations (Northern Ireland, Scotland and Wales). There is currently no finalised closing date for any of these cohorts. The aim is exactly the same as for the English Cohort, so separate final data files per cohort will be collated and sent to the research team, in the same format as before.
Processing:
A csv file will be prepared to be sent to HSCIC for list cleaning with details of patient surnames and forenames, NHS numbers and date of births. Picker Institute Europe require HSCIC to identify those patients that have died as well as providing back the patient's NHS Numbers, forenames and surnames, addresses and postcodes.
** update December 2016 **
The identifiers for those men who consented to the original survey were flagged by the Picker Institute and Public Health England (PHE) informed to update their cohort details. This means that the data shared with NHS Digital will be for those men who consented only.
PHE will send the cohort details (30,465) to the Picker Institute, who will then pass these onto NHS Digital for list cleaning with the same output as previously provided. Patient objections will apply.
Following the process of the first run, the cohort (split into part A (3000) and part B (27,645)) will be list cleaned multiple times. The first clean will occur once the agreement is approved to allow preparation of the survey once the cleaned data is received. Then subsequent cleans will be performed as needed (3x per cohort) as follow up letters are sent to the men regarding their response.

Objectives:
The Clinical Trials Research Unit (CTRU) at the Leeds Institute of Clinical Trials Research (LICTR), University of Leeds, believe that the cardiology community requires an appropriately powered, randomised controlled trial of non-invasive ischaemia assessment (functional imaging) to determine diagnosis and patient management.
LICTR know that invasive angiography rates are already too high, and that they will increase further if the NICE guidelines (CG95) are followed. LICTR know that from a previous small single centre trial (CECaT), that using functional testing (Cardiac Magnetic Resonance Imaging (CMR), Single Photon Emission Computed Tomography (SPECT), stress echo) invasive angiography could be avoided in 20-25% of patients.
LICTR also know that patients rightly want to avoid unnecessary angiography if at all possible, but to date no clinical trial has tested the safety of this type of strategy in terms of clinical outcome.
LICTR propose the CE-MARC 2 trial, which would be a major advance from the simple and usually small diagnostic accuracy studies that are all too prevalent in the imaging literature. Having benchmarked the diagnostic performance of CMR and shown superiority against SPECT in the CE-MARC study, CTSU now propose to evaluate 3T CMR prospectively in a three-arm trial to assess whether a CMR-guided management strategy is superior to current best clinical practice (based upon either the principles of NICE CG95 or AHA SPECT appropriateness criteria.
This type of study would not previously have been acceptable to clinicians without the findings from CE-MARC defining its diagnostic performance.
It is of note that the widely used modality of SPECT has never been prospectively tested as CTSU propose here for CMR.
For the NHS, the objective of CE-MARC 2 is to provide robust evidence of:
a) Potential improvement in patient care/Health-Related Quality of Life (HRQOL)/outcomes;
b) A strategy by which to reduce unnecessary invasive angiography (by a true replacement test rather than an additional test in the diagnostic pathway);
c) Cost effectiveness of Cardiac Magnetic Resonance Imaging (CMR) in order to inform future NHS capital investment (as general Magnetic Resonance (MR) systems are replaced this study will help inform key capital purchase decisions on whether a 3T system is justified for cardiovascular work).
The purpose of CEMARC 2 is to understand the best method of managing patients with anginal chest pain. This will be quantified by measuring the number of unnecessary angiograms conducted in each arm of the trial.
In line with secondary objectives of the CEMARC 2 Trial, a comparison of safety across the three arms of the trial will be made by measuring cardiovascular events, including cardiovascular cause of death defined as;
• Fatal Myocardial Infarction
• Heart failure
• Acute Unexpected Death
• Stroke
• Pulmonary Embolism
• Cardiovascular Procedure-Related
• Other Cardiovascular
• Unknown
Comparison of safety relates to the long-term follow-up. The University of Leeds will use the events data to establish that MRI/SPECT strategies no not result in excess major cardiovascular events down the line due to missed coronary disease.
To summarise, the study will consider whether patients in MRI/SPECT arms either have less events than NICE patients, or that said events happen much later.
Expected Benefits:
The results of the CEMARC 2 clinical research trial are expected to inform the next update of NICE guideline CG95 (Chest pain of recent onset: assessment and diagnosis) and therefore have enormous potential to change NHS practice, but also to inform future NHS capital expenditure.
The research question is highly relevant to a large number of patients: what is the best initial test for patients coming to an outpatient clinic with chest pain that is suspected stable angina? It is well accepted that a variety of investigations may be used to diagnose Coronary Heart Disease and to determine the need for coronary revascularisation. Whilst the NICE guidelines (CG95) have provided a structured and evidence-based approach to the diagnosis of patients with chest pain, they are not without problems. Full adoption of the guidelines could lead to an increase in invasive angiography, when the University of Leeds know that the rate of unnecessary angiography is already high.
From the involvement of expert patient at the design stage of this study the University of Leeds know that unnecessary angiography is something patients are particularly keen to avoid.
The benefits to patients will be a reduction of unnecessary invasive angiography which would also constitute a cost saving to the NHS.

Previous analyses
The analysis of CE-MARC2 is being performed in a staged manner. The initial primary analysis began when the final patient reached one year’s follow-up, and analysed the primary endpoint (unnecessary angiography) as well as the safety data accrued so far (complications, positive angiography and major adverse cardiovascular events (MACE).
This primary analysis was completed in April 2016 with a manuscript submitted to JAMA that was subsequently published in September 2016. (JAMA. 2016;316(10):1051-1060. doi:10.1001/jama.2016.12680). The results were also presented at the European Society of Cardiology (ESC) 2016 Annual Congress in Rome on 29th August 2016. The summary of the findings was that CMR and SPECT patients saw a substantially lower rate of unnecessary angiography compare to those managed using a NICE Guidelines based management strategy, and – based on the minimum 12 months follow-up at the time – there was no significant difference in the subsequent rates of MACE.
Contemporary coverage of the results included a favourable review from Richard Lehman (BMJ) in a round-up of journal articles, noting that the CE-MARC2 trial “explicitly [set] patient importance above public health importance, though it ended up informing both.” (http://blogs.bmj.com/bmj/2016/09/19/richard-lehmans-journal-review-19-september-2016/) as well as an editorial from the British Cardiovascular Society calling on NICE to review and update guidelines for assessment of stable angina. (Aung, N.
Role of invasive angiography in suspected coronary artery disease: Results from the CE-MARC 2 Trial. BCS Editorial. 23rd September 2016. https://www.bcs.com/pages/news_full.asp?NewsID=19792516)
Further Analyses
The second analysis will be performed after all participants have completed 3 years in the study, which is in March 2018. ONS data is required to April 2018, when this is received an additional safety analysis will be completed at the end of this period. Analysis of this data will be performed along with the analysis of the 3 year Quality of Life data.
Timelines have yet to be confirmed for analysis completion and dissemination, however we are optimistic that these results publication can at least be submitted before the end of 2018.
Trial results will be more widely disseminated to patient and public groups and to the lay community. Should the latest analysis show that the intervention has an appropriate safety profile in relation to its demonstrated benefit of fewer unnecessary angiographies, the results will further inform NICE guidance and influence NHS practice in this area.
No outputs will ever identify any individual, organisation, nor include any record level data.
Processing:
The University of Leeds receive data for an identified cohort for the CEMARC 2 trial, for whom the University of Leeds provide identifiers already collected from participants as part of the trial dataset (and with their consent). These are: name, address, NHS number and date of birth. This ensures the University of Leeds minimise the chance of receiving data for anyone other than consenting trial participants. The University of Leeds need to receive identifiable data to ensure that the University of Leeds have data for the correct individuals and match this with the existing trial data set.
Data will be processed by the trial statisticians at the Clinical Trials Research Unit, Leeds Institute for Clinical Trials Research (LICTR) at the University of Leeds. All individuals with access to the data are employees of the University of Leeds.
It will be securely stored on CTRU systems with access only granted to the statistical team. Data will not be accessed by any third parties, nor will it be accessible across multiple organisations.
Data will be linked with existing CEMARC 2 Trial datasets (existing CEMARC2 Trial datasets consist of patient demographics and results from diagnostic tests, patients have given written informed consent to participate in the trial and the identifiers the University of Leeds are collected as part of the trial - data provided by participants and researchers in accordance with the REC-approved trial protocol and participant consent). The data will be used to determine safety endpoints in terms of cardiovascular event rates, which include cardiovascular cause of death as defined above.
Data will not be used for any other purposes: it will not be used for commercial purposes, nor for direct marketing purposes.
ONS Terms and conditions will be adhered to.
All organisations party to this agreement must comply with the Data Sharing Framework Contract requirements, including those regarding the use (and purposes of that use) by “Personnel” (as defined within the Data Sharing Framework Contract ie: employees, agents and contractors of the Data Recipient who may have access to that data).

Yielded Benefits:
Outputs:
No new or further data will be provided under this version of the agreement. A short term extension is in place as a pragmatic approach to enable legal retention of already disseminated data. This agreement allows retention of data, but not permission to otherwise process it.
These outputs will include an analysis of time until first major adverse cardiovascular event (MACE), and the incidence of at least one of these events, as well as the individual components: cardiac death, arrhythmia, myocardial infarction, heart failure, unplanned revascularisation, stroke/TIA, Acute Coronary Syndrome.
The CEMARC trial team will aim to submit these findings to a high impact general medical journal (e.g. New England Journal of Medicine, Lancet, Journal of the American Medical Association) in the first instance. Conference and scientific meeting presentations will follow, as was the case with earlier outputs (see 5d iii. Yielded benefits).
The outputs are aimed at the entire medical community, hence the trial team aim to publish in a general medical journal rather than a specialist cardiovascular publication. CEMARC have an excellent track record of achieving this with the main CEMARC papers having been published in the Lancet and Annals of Internal Medicine (see 5d iii. Yielded benefits).
All outputs will contain only data that is aggregated with small numbers suppressed in line with the HES Analysis Guide.

The flow of identifiers, which have already been sent to NHS Digital under a previous version are as follows:
Surname/Forename Name
Address
Date of birth
Gender
NHS Number
Study ID the number a participant is allocated when they enter the study.
Data will be downloaded from the NHS Digital link and the data file saved in a secure folder on the P-Drive by a named member of the study team. Data will be entered into a secure password protected database held locally at the Clinical Trials research Unit (CTRU) at the UoL, by a data management assistant who will transcribe the data onto a case report form (CRF). Data will then be entered into a secure password protected database held locally at the UoL by a trained member of the data management team.
A copy of this CRF will then be sent to Leeds Institute of Cardiovascular and Metabolic Medicine (LICAMM) at the UoL, to be securely filed with their copy of the participant file and the original filed in a secure tambour with other trial documentation at the CTRU. This will be securely filed with their copy of the participant file. Any electronic scanned versions will then be deleted. The original CRF will be filed in a secure tambour with the participant study files that include CRFs and any correspondence over data cleaning at the CTRU.
The data will then be processed by the trial statistician at the Clinical Trials Research Unit, Leeds Institute for Clinical Trials Research (LICTR) at the UoL.
All individuals with access to the data are substantive employees of the UoL, data will only be accessed by individuals with the CTRU who are directly involved with the NHS digital transfer and analysis of the data (Trial statisticians and data management assistant).
