Objectives:
NHS Digital has been provided with the necessary powers to support the Secretary of State’s response to COVID-19 under the COVID-19 Public Health Directions 2020 (COVID-19 Directions) and support various COVID-19 purposes, the data shared under this agreement can be used for these specified purposes except where they would require the reidentification of individuals.
GPES data for pandemic planning and research (GDPPR COVID 19)
To support the response to the outbreak, NHS Digital has been legally directed to collect and analyse healthcare information about patients from their GP record for the duration of the COVID-19 emergency period under the COVID-19 Directions.
The data which NHS Digital has collected and is providing under this agreement includes coded health data, which is held in a patient’s GP record, such as details of:
• diagnoses and findings
• medications and other prescribed items
• investigations, tests and results
• treatments and outcomes
• vaccinations and immunisations
Details of any sensitive SNOMED codes included in the GDPPR data set can be found in the Reference Data and GDPPR COVID 19 user guides hosted on the NHS Digital website. SNOMED codes are included in GDPPR data.
There are no free text record entries in the data.
The Controller will use the pseudonymised GDPPR COVID 19 data to provide intelligence to support their local response to the COVID-19 emergency. The data is analysed so that health care provision can be planned to support the needs of the population within the CCG area for the COVID-19 purposes.
Such uses of the data include but are not limited to:
• Analysis of missed appointments - Analysis of local missed/delayed referrals due to the COVID-19 crisis to estimate the potential impact and to estimate when ‘normal’ health and care services may resume, linked to Paragraph 2.2.3 of the COVID-19 Directions.
• Patient risk stratification and predictive modelling - to highlight patients at risk of requiring hospital admission due to COVID-19, computed using algorithms executed against linked de-identified data, and identification of future service delivery models linked to Paragraph 2.2.2 of the COVID-19 Directions. As with all risk stratification, this would lead to the identification of the characteristics of a cohort that could subsequently, and separately, be used to identify individuals for intervention. However the identification of individuals will not be done as part of this data sharing agreement, and the data shared under this agreement will not be reidentified.
• Resource Allocation - In order to assess system wide impact of COVID-19, the GDPPR COVID 19 data will allow reallocation of resources to the worst hit localities using their expertise in scenario planning, clinical impact and assessment of workforce needs, linked to Paragraph 2.2.4 of the COVID-19 Directions:
The data may only be linked by the Data Controller or their respective Data Processor, to other pseudonymised datasets which it holds under a current data sharing agreement only where such data is provided for the purposes of general commissioning by NHS Digital. The Health Service Control of Patient Information Regulations (COPI) will also apply to any data linked to the GDPPR data.
The linked data may only be used for purposes stipulated within this agreement and may only be held and used whilst both data sharing agreements are live and in date. Using the linked data for any other purposes, including non-COVID-19 purposes would be considered a breach of this agreement. Reidentification of individuals is not permitted under this DSA.

Objectives:
Invoice Validation
Invoice validation is part of a process by which providers of care or services get paid for the work they do.
Invoices are submitted to the Clinical Commissioning Group (CCG) so they are able to ensure that the activity claimed for each patient is their responsibility. This is done by processing and analysing Secondary User Services (SUS+) data, which is received into a secure Controlled Environment for Finance (CEfF). The SUS+ data is identifiable at the level of NHS number. The NHS number is only used to confirm the accuracy of backing-data sets and will not be used further.
The legal basis for this to occur is under Section 251 of NHS Act 2006.
Invoice Validation with be conducted by NHS Bristol, North Somerset and South Gloucestershire CCG
The CCG are advised by NHS Bristol, North Somerset and South Gloucestershire CCG whether payment for invoices can be made or not.
Risk Stratification
Risk stratification is a tool for identifying and predicting which patients are at high risk or are likely to be at high risk and prioritising the management of their care in order to prevent worse outcomes.
To conduct risk stratification Secondary User Services (SUS+) data, identifiable at the level of NHS number is linked with Primary Care data (from GPs) and an algorithm is applied to produce risk scores. Risk Stratification provides a forecast of future demand by identifying high risk patients. Commissioners can then prepare plans for patients who may require high levels of care. Risk Stratification also enables General Practitioners (GPs) to better target intervention in Primary Care.
The legal basis for this to occur is under Section 251 of NHS Act 2006 (CAG 7-04(a)).
Risk Stratification will be conducted by South Central and West Commissioning Support Unit
Commissioning
The NHS and local councils have come together in 44 areas covering all of England to develop proposals to improve health and care. They have formed new partnerships – known as sustainability and transformation partnerships – to plan jointly for the next few years.
Sustainability and transformation partnerships build on collaborative work that began under the NHS Shared Planning Guidance for 2016/17 – 2020/21, to support implementation of the Five Year Forward View. They are supported by six national health and care bodies: NHS England; NHS Improvement; the Care Quality Commission (CQC); Health Education England (HEE); Public Health England (PHE) and the National Institute for Health and Care Excellence (NICE).
The CCG is part of the Bristol, North Somerset and South Gloucestershire Sustainable Transformation Partnership. The STP is responsible for implementing large parts of the 5 year forward view from NHS England. The STP is implementing several initiatives:
- Putting the patient at the heart of the health system
- Working across organisational boundaries to deliver care and including social care, public Health, providers and GPs as well as CCGs
- Reviewing patient pathways to improve patient experience whilst reducing costs e.g. reduce the number of standard tests a patient may have and only have the ones they need
- Planning the demand and capacity across the healthcare system across 2 CCGs to ensure we have the right buildings, services and staff to cope with demand whilst reducing the impact on costs
- Working to prevent or capture conditions early as they are cheaper to treat
- Introduce initiatives to change behaviours e.g. move more care into the community
- Patient pathway planning for the above
To ensure the patient is at the heart of care, the STP is focussing on where services are required across the geographical region. This assists to ensure delivery of care in the right place for patients who may move and change services across the CCG.
The CCG will work proactively and collaboratively in the STP to redesign services across boundaries to integrate services.
The CCG will use pseudonymised data to provide intelligence to support the commissioning of health services. The data (containing both clinical and financial information) is analysed so that health care provision can be planned to support the needs of the population within the STP area.
The CCG commissions services from a range of providers covering a wide array of services. Each of the data flow categories requested supports the commissioned activity of one or more providers.
The following pseudonymised datasets are required to provide intelligence to support commissioning of health services:
- Secondary Uses Service (SUS+)
- Local Provider Flows
o Acute
o Ambulance
o Community
o Demand for Service
o Diagnostic Service
o Emergency Care
o Experience, Quality and Outcomes
o Mental Health
o Other Not Elsewhere Classified
o Population Data
o Primary Care Services
o Public Health Screening
- Mental Health Minimum Data Set (MHMDS)
- Mental Health Learning Disability Data Set (MHLDDS)
- Mental Health Services Data Set (MHSDS)
- Maternity Services Data Set (MSDS)
- Improving Access to Psychological Therapy (IAPT)
- Child and Young People Health Service (CYPHS)
- Community Services Data Set (CSDS)
- Diagnostic Imaging Data Set (DIDS)
- National Cancer Waiting Times Monitoring Data Set (CWT)
The pseudonymised data is required to for the following purposes:
§ Population health management:
• Understanding the interdependency of care services
• Targeting care more effectively
• Using value as the redesign principle
• Ensuring we do what we should
§ Data Quality and Validation – allowing data quality checks on the submitted data
§ Thoroughly investigating the needs of the population, to ensure the right services are available for individuals when and where they need them
§ Understanding cohorts of residents who are at risk of becoming users of some of the more expensive services, to better understand and manage those needs
§ Monitoring population health and care interactions to understand where people may slip through the net, or where the provision of care may be being duplicated
§ Modelling activity across all data sets to understand how services interact with each other, and to understand how changes in one service may affect flows through another
§ Service redesign
§ Health Needs Assessment – identification of underlying disease prevalence within the local population
§ Patient stratification and predictive modelling - to identify specific patients at risk of requiring hospital admission and other avoidable factors such as risk of falls, computed using algorithms executed against linked de-identified data, and identification of future service delivery models
The pseudonymised data is required to ensure that analysis of health care provision can be completed to support the needs of the health profile of the population within the CCG area based on the full analysis of multiple pseudonymised datasets.
Processing for commissioning will be conducted by South Central and West Commissioning Support Unit and Outcomes Based Health (OBH)
Yielded Benefits:
Data used in support of ongoing transformation plans to deliver against savings plan. To date, around £28.5m of savings identified. Work supported by analyst use of data to initially develop and savings plans and identify impacts. Ongoing activity monitoring support and reporting. Data used to monitor impact of major system changes, including the overnight closure of an AE department within the BNSSG area. Activity data used to measure impact on system and patients and inform decision making around the process. Development of bespoke reporting tools which are used in a range of settings, including an unwarranted practice variation tool which has been used to identify referral outliers and inform further work to understand activity. Continued use of data in support of monitoring around delivery of constitutional standards, with standards achieved in a number of measures. Data used to help inform plans aimed at achieving targets in other areas requiring improvement, by understanding drivers behind performance and identifying opportunities for improvements. Identify data and performance issues at provider organisations to initiate discussions at contract meetings which has led to: further analysis to identify root causes and mitigating actions; using contractual levers i.e. issuing contractual notices (Contract Performance Notices and Information Breach Notices) to facilitate improvement through joint investigations and remedial action plans and; identifying good practice and lessons learned to ensure consistency across our 3 providers to support equity of provision. Provide assurance to CCG Governing Body and Healthy Together STP (System Delivery Oversight Group): that contracts with providers are being managed effectively and; how the BNSSG population is being served; Provides evidence to STP system wide groups on areas of good and poor performance such as urgent care, planned care and cancer to share learning, identify improvements and develop joint plans. Support the work with providers to develop joint activity plans, performance trajectories and strategies. As a CCG we are an evidence-based organisation using data to underpin our decision making processes. Key achievements which have been informed by use of data include: Funding mental health support in schools: we became the first city in the country to fund a mental health-focused training package for staff in every primary and secondary school, working closely with Bristol City Council. The training is designed to raise the profile of Child and Adolescent Mental Health Services (CAMHS), with the focus on early intervention to make a significant difference to young people’s lives. Advancing our dementia care: We have established leading dementia wellbeing services, with around 2,000 patients benefiting from specialised support last year. A key feature is that people are never discharged from the service and can access support whenever they need it. We’re making continued investments and the number of people the service supports has nearly doubled over the last 12 months. Sustainability and Transformation Partnership: We developed a new plan to guide our commissioning activity until 2021 as a partnership between Bristol, North Somerset and South Gloucestershire CCGs. After drafting the plan together, we involved the community and other clinical groups to gain their input. We had meetings with the three local authority health scrutiny committees and community volunteers. Our work together set us up to develop the best possible healthcare services for our population’s needs in the coming years. Designing healthcare with our young people: We held a major consultation to find out what local young people, their parents and professionals involved in their care, thought of our community health services. We received over 1,200 ideas and have been using that feedback to shape children’s and young people’s health services. Improving hospital discharge for older people: Our Discharge to Assess (D2A) scheme speeds up hospital discharge times for older patients, helping them get home quicker. The D2A team support patients to be discharged and assess ongoing care at home, on the same day, by community teams of social workers, nurses, physiotherapists and occupational therapists. The scheme has helped 20 people who would otherwise be in hospital receive therapy in their own homes and enabled us to save a total of 376 hospital bed days. Appointing a new community healthcare services provider: In partnership with NHS England and North Somerset Council, we appointed North Somerset Community Partnership (NSCP) to provide community healthcare services. They provide all adult and some children’s community health services and specialist services, such as those for people with Parkinson’s disease, until April 2019. Developing better out-of-hospital care: Helping people to live safely and independently at home as they age has been a high priority. We’ve introduced several initiatives to help people get better outside of hospital, from helping them discharge as soon as they’re fit to leave, to outpatient appointments in the community, and working with Age UK to provide better support to people as they age. Transforming community services for children: We re-procured children’s community health services for Bristol and South Gloucestershire. This involved a partnership of five commissioning organisations working together to develop a cost-effective service for the whole area that recognises specific local needs, delivering coordinated care to children, young people and families. Tackling diabetes and promoting self-care: We joined the second wave of the national Diabetes Prevention Programme in April 2017, building on a pilot at Leap Valley GP practice in Emersons Green, Bristol. Together with Bristol and South Gloucestershire CCGs, we’ve also since been selected to pilot the digital stream, which aims to establish whether digital interventions are effective in supporting behaviour change in people with non-diabetic hyperglycaemia (NDH) and overweight and or obese individuals.

Outcomes Based Healthcare:
Outcomes are often described as those things that matter to people, and are typically the end results of care across complete care pathways. Access to a population-level view of all people with relevant long-term conditions, in near real-time, is the essential starting point for accurate outcome measurement. It is also an essential enabler supporting quality process improvement within care pathways.
Outcomes measured using existing clinical and administrative data typically measure the reduction in illness, disease and complications, and their severity, in addition to system activity metrics.
Measuring outcomes aims to refocus providers (including health and social care providers) to work together to reduce the burden of disease. By setting longer-term targets and improvement trajectories for each outcome, providers can focus their efforts on improving these outcomes, for specific population groups, over a period of years.

Outcomes Based Healthcare:
The main outputs are aggregated monthly values for each outcome (with small number suppression, including any values under 5). The aggregated monthly outcomes data will be made available through OBH’s online tool (available to named individuals in the CCG and CCG commissioned providers only) via a secure login.
This enables the CCGs and to:
- visualise baselines for each outcome
- set improvement trajectories
- monitor outcomes on an on-going basis.
In addition, the CCGs will receive an information schedule describing the outcomes to be monitored, the technical description, and annual baseline data for each outcome.
All outputs will be delivered within the timescales of the contract between OBH and the CCGs.
Processing:
Data must only be used as stipulated within this Data Sharing Agreement.
Data Processors must only act upon specific instructions from the Data Controller.
Data can only be stored at the addresses listed under storage addresses.
The Data Controller and any Data Processor will only have access to records of patients of residence and registration within the CCG.
Patient level data will not be shared outside of the CCG unless it is for the purpose of Direct Care, where it may be shared only with those health professionals who have a legitimate relationship with the patient and a legitimate reason to access the data.
All access to data is managed under Roles-Based Access Controls
CCGs should work with general practices within their CCG to help them fulfil data controller responsibilities regarding flow of identifiable data into risk stratification tools.
No patient level data will be linked other than as specifically detailed within this agreement. Data will only be shared with those parties listed and will only be used for the purposes laid out in the application/agreement. The data to be released from NHS Digital will not be national data, but only that data relating to the specific locality and that data required by the applicant.
The DSCRO (part of NHS Digital) will apply Type 2 objections before any identifiable data leaves the DSCRO.
NHS Digital reminds all organisations party to this agreement of the need to 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)
Segregation
Where the Data Processor and/or the Data Controller hold both identifiable and pseudonymised data, the data will be held separately so data cannot be linked.
All access to data is auditable by NHS Digital.
Data for the purpose of Invoice Validation is kept within the CEfF, and only used by staff properly trained and authorised for the activity. Only CEfF staff are able to access data in the CEfF and only CEfF staff operate the invoice validation process within the CEfF. Data flows directly in to the CEfF from the DSCRO and from the providers – it does not flow through any other processors.

Objectives:
Statistical and mathematical modelling is the process of taking a real world problem or system and creating a simplified description of it (a model) – using mathematical concepts and language. The model is designed to capture features of interest in the real world system and provide means to study the interrelation of those features, make predictions, or study the possible effects of changing some of those features.
In a healthcare planning context, a model will typically take a mixture of quantitative/numerical variables (corresponding to concepts such as arrivals at a hospital, length of stay, age, cost, lab results, clinical scores, or counts of activity) and categorical variables (corresponding to things like type of illness, sex, or smoking status), and codify the relationships between them using mathematical formulae.
In situations where outcomes are uncertain (such as when making predictions, when there is potential measurement error, or when there is a random element to when or how individual events occur), the concept of a probability distribution is particularly useful in constructing models. A probability distribution takes the measure of interest (hospital length of stay, for example) and quantifies the chance that each value of that measure occurs. Real life data can often be well approximated by theoretical probability distributions which are described by established mathematical formulae and whose properties are well understood. This is a more fine-grained (and realistic) approach than simply describing the measure by its average (mean or median) value alone.
An extremely simple and unrealistic mathematical model might describe, for example, length of stay in an inpatient ward as a simple formula which calculates the predicted length of stay for a given patient would be some constant multiplied by their age on admission. A more sophisticated model might predict the length of stay based on a combination of age, sex and frailty, multiplying each by a constant and adding them together to get the expected length of stay.
An alternative model might account for some of the natural random variability in the process – obviously, not all patients admitted to a ward where the average length of stay is 3 days will stay for exactly 3 days. To account for this, the model might instead predict lengths of stay for individual patients by choosing values at random from a probability distribution. The particular distribution could be chosen so that it agrees with some easily obtainable summary measures (such as the mean and standard deviation) of the actual data. The choice of length of stay value to use from the distribution could be made by a process similar to flipping a coin or rolling a die, then reading of the value which corresponds to the number which comes up. More sophisticated approaches, and/or ones which made different assumptions, could also be taken.
The terms “events” and “shocks” in the sections below have been used interchangeably to refer to factors which affect the generalisability of the data or its reflection of system behaviour expected/normal circumstances, including both data quality problems and deliberate operational interventions.
NHS Bristol, North Somerset and South Gloucestershire Clinical Commissioning Group (BNSSG CCG) commissions, plans and monitors healthcare services for a population of approximately 1.1 million people in a sub-region of South West England based around the Bristol urban centre. It was created in 2018 by the merger of three predecessor organisations and as part of that process took on greatly enhanced responsibility for system-wide data analytics, including the creation of a specific modelling and analytics (M&A) team. This team’s remit is to provide advanced analytical support on both business-as-usual (BAU) and transformation projects to the CCG and the local Sustainability and Transformation Partnership/emergent Integrated Care System. This involves work with local acute, mental health, community and primary care providers, and to enhance existing business intelligence and analytics capacity in the system by providing access to more sophisticated and accurate methods and outputs than were historically available. Note that this reorganisation included the in-housing of many analytic functions traditionally out-sourced to Commissioning Support Units, hence BNSSG CCG data requirements may be more extensive than those for CCGs in which analytics expertise is bought from an external supplier.
Standard reporting against nationally reportable standards, and traditional, basic, activity and cost summaries are routinely produced by non-specialist analysts using SUS (Secondary Use Services) SEM (a specific file format) data restricted to the CCG’s registered population.
However, data which is both more granular and raw in definition, and more extensive in geographical coverage (for the whole of England), is required by highly specialised mathematical analysts within the CCG’s M&A team to construct metrics needed for more sophisticated modelling techniques. The BNSSG CCG will use Hospital Episode Statistics (HES) data to derive robust estimates of key operational metrics including probability distributions for inpatient hospital care length of stay (LOS), inpatient, outpatient, and emergency arrival rates, waiting times and associated measures (as opposed to single number summary statistics). All of these will be determined for defined clinical, demographic, time-period and potentially geographic (e.g. urban vs rural) and provider-type profiles in order to make them meaningfully applicable to operational and strategic planning, service redesign, and intervention analysis projects.
The analysis will use pseudonymised non-sensitive patient-level data to derive empirical probability distributions for the processes of interest, and from these fit theoretical distributions which can be used in simulation modelling and statistical analysis of existing and proposed patient pathways. Using local data alone is not a reliable option since; when considering activity within specified clinical, demographic and time profiles the effects of individual extreme values in the data, periods of poor data quality/missing data, service transfers, interventions and system reconfiguration, as well as the inevitable small numbers in some groupings (even in a population of greater than 1 million), mean derived distributions would be unreliable and the level of variability which would need to be included in estimate would severely constrain its usefulness. By both greatly increasing the effective “sample size” and smoothing out the effect of local time-limited service changes and data quality issues, using all-England patient level data will mitigate the effect of these events/shocks in any given local system (such as temporary consultant vacancies, ward closures, service suspensions, electronic system changes, etc.) and allow for the construction of robust, practically usable distribution estimates. These will in turn facilitate improved accuracy in projection, planning and monitoring of activity which relies on models built using those metrics. Using data at an all-England level as opposed to single CCG level is consistent with the approach historically taken by the NHS nationally, for example in the construction of NHS England’s Indicative Hospital Activity Model (IHAM).
Examples of the type of modelling which the outputs of this project will be used to support include (but are not restricted to): discrete event simulation (DES) modelling of multi-stage patient pathways which include both hospital admission and outpatient appointments; system dynamics modelling of urgent care patient flows; and comparison of local admitted patient care pathway performance for specific treatments following local policy interventions to expected “do nothing” scenarios. Modelling is currently being done in all of these contexts within BNSSG, but the precision, accuracy and interpretability of the results is constrained by local data limitations and could be greatly improved by the use of more robust distributions and metrics, derived from data with national coverage.
Because much hospital activity exhibits seasonality, and to account for the effect of year-on-year changing policy and financial incentives, a minimum of three years of data is required to derive reliable estimates. To make it relevant to future and current planning and analysis, the data needs to be from the most recent available periods. To ensure the maximum possible feasible data minimisation, this request has thus been restricted to the most recent three years of data. HES data has been chosen because it contains a sufficient degree of granularity to allow sub-setting into groups which match how specific services are (or may be) constructed, in terms of which patient groups they serve.
Expected Benefits:
The potential benefits of accurate and reliable operational planning for healthcare service delivery in general are well established. It is also well established that unreliability of projections and metrics can make such planning difficult.
This data is being requested to support a project which directly addresses that problem by seeking to improve the accuracy and reliability of analytics used for practical, local system-wide operational planning of CCG-level healthcare services.
As already referred to in previous sections, reliance on analysis solely of local data to derive, for example, expected arrival, admission and length of stay metrics for particular types of service, can be subject to local events and shocks which mask the "natural" metrics of the service and distort analysis based solely on that local data. Additionally, when analysing data at a fine level of granularity (e.g. deriving metrics for a highly specialised service), the "sample size" in the local data is in some cases too small to make valid statistical inferences from, or else the small sample size leads to unhelpful levels of uncertainty in the estimates. This poses a problem when working to construct accurate and reliable operational and contract plans for the local system.
The national data will improve BNSSG CCG’s picture of (for example) underlying growth and enable the CCG to "fill in the gaps" which are inevitable in low sample sizes, and that can cause volatility in any resulting projections. For example, where an otherwise irregular surge in activity - perhaps only due to the opening of additional clinic slots - can have a material impact on any associated growth figures, which would not necessarily be borne-out in future years. Or where the odd very long LOS can have a drastic effect on the averages deduced.
The outputs will have a direct effect of decision making in a variety of strategic and operational settings. For example, inpatient length of stay (LOS) measures will be used in modelling which directly informs choices of capacity (in terms of bed numbers, staffing etc.) in service reconfigurations and design of new services. This includes multi-organisational patient care pathways - activity metrics will be used directly in the production and verification of activity projections used for operational planning and funding of future service levels; activity, LOS, and other measures will be used to derive more realistic performance measures for local services, allowing the generation of models to detect variations from expected activity.
The availability of robust metrics derived from data with a national coverage will greatly enhance the reliability of these modelling outputs with expected operational and financial benefits in the local health system, and potential for similar benefits to be realised by other areas building on the BNSSG work. The financial scale of the impact is potentially very large – the CCG manages a budget of more than £1bn per year and decisions about funding particular capacity levels, based on future activity estimates, is in the order of millions of pounds each year, and the operational effect on correct service capacity estimates has a non-quantitative but significant effect on patient care and experience, in terms of waiting times, capacity to deliver appropriate treatment in urgent care settings, and the ability of the local system to absorb shocks in terms of changes to and variation in activity levels.
Initial use of the outputs in a local context would be within a matter of months and some wider dissemination of results and measures could follow soon after, while detailed assessment of the utility of the derived metrics would be assessed and adjusted over a period of subsequent financial years up to the project end in 2023.
National benefits
Probability distribution library
A key high value initial output of NHS Bristol, North Somerset and South Gloucestershire CCG's work with the national HES data will be the creation of a directory of length of stay/arrival rate probability distributions for a wide range of service point types, which can be scaled to match local requirements based on locally estimated averages.
For example, distributions associated with component service points of a knee surgery pathway, identified by filtering the data by a combination of treatment specialty, diagnosis, and procedure codes (necessary to construct real-life services from the data – from experience, NHS Bristol, North Somerset and South Gloucestershire CCG knows that while simple use of treatment specialty codes or high level diagnostic measures in isolation may be useful for some accounting purposes, it maps poorly onto the operational representation of actual services).
Distributions will be derived at these generic service levels, but more specific results will also be produced by further filtering by demographics, geography and/or provider type. The purpose of this further filtering will be to distinguish expected unique characteristics of the service/component wards and clinics in a range of meaningfully defined practical settings. One such distinction of settings could be a knee surgery pathway at a large specialist urban hospital with a population skewed to a younger age range, versus the same service at a smaller rural hospital serving a substantially older population.
Depending on the service type, and whether filtering yields a sufficient quantity of records in the given setting, time-specific distributions may also be derived for some service types (to account for time of day, day of week, or time of year seasonal changes in arrival rates or lengths of stay).
Distributions will be fitted to the data using standard techniques (such as maximum likelihood, moment matching etc.), implemented through the statistical programming environment R, which is rapidly gaining traction as the tool of choice for advanced analytics in the NHS.
The resulting library of arrival and length of stay distributions will (by design) be equally useful to any CCG, STP, ICS or other system-planning NHS organisation (and indeed to providers engaged in planning of pathways substantively contained within their own organisations) with a sufficiently advanced analytic workforce. The distributions would form a set of generic building blocks which a wide range of hypothetical services, in a wide range of practical settings, could be constructed.
They will effectively form a reference set of expected measures which could be used to construct models of activity when designing a new service which does not currently exist, when modifying the configuration of an existing service, or when assessing the performance of an existing service against the assumed generic case. By design, they will be generically applicable to any area of the country – local circumstances will be accounted for by choosing a set of measures which capture characteristics which analysts/modellers intend to be present in their local system, rather than using the geographical source of the data as a proxy for these characteristics (except when a geographical variable is the explicit characteristic of interest, e.g. in distinguishing between urban and rural areas).
One direct use of these measures will be in demand and capacity models, for which length of stay is a key input. In constructing simulation models (such as discrete event simulation) – one of the barriers to uptake of simulation within the NHS is the lack of availability of appropriate data to inform such models. NHS Bristol, North Somerset and South Gloucestershire CCG has separately developed its own simulation software which will be distributed nationally to NHS organisations in the coming months, and the library of distributions constructed using HES data could be subsequently disseminated to organisations using that (or other) software.
Relationship between day of discharge and length of stay (and other measures)
NHS Bristol, North Somerset and South Gloucestershire CCG has already instigated a local study into the statistical relationship between the day of week on which patients are discharged and the total hospital length of stay of those groups of patients, and also into potentially associated measures such as 30-day readmission rates. The stability of the results is potentially affected by non-recurrent factors in local data but by using all-England HES data, subsetted explicitly for the relevant characteristics, it should be possible to derive stable results which are generally applicable nationally and across specific areas. These results could then be used to assess the desirability of interventions to modify day-of-week discharge patterns and resource allocation in local systems.
From the local investigations already performed, it appears that there could be substantial scope for improving hospital efficiency, since many discharges appear to be delayed over the weekend until early the following week. Reducing these delays through a 7-day service would reduce hospital length of stay by 10%, which would correspond to material bed number savings, while receiving none of the drawbacks. National data is required to test this finding further, in both accounting for potential sample size insufficiency and checking whether local results hold nationally.
Other projects
There are a number of other system-level projects, both in scoping and already started, for which national data would be beneficial. For example, in re-visiting the 85% bed occupancy target where work in underway to assess whether this commonly-used target for average bed occupancy should be tailored to ward and service types. The general principle is that more variability in arrivals and length of stay mean the average occupancy target should be pitched lower (in order to accommodate the greater impact of peaks and troughs), while less variability would mean being able to make more routine use out of the bed base with a lesser threat of damaging pinch points.
Outputs:
The following outputs are anticipated to be created upon accessing the HES data from NHS Digital.
Specialty-level growth projections with updated estimates taking into account national trends - this is a major project due for completion 2023.
Specialty-level length of stay estimates, with updated estimates taking into account national information - this is a major project due for completion 2023.
A range of similar analyses to determine appropriate metrics to support system-wide operational planning and monitoring (including but not restricted to demand and capacity planning). Full detail and timelines are to be reactively determined from having first completed initial examination and assessment of the data, but this is not anticipated to be extending beyond 2023.
The majority of these outputs (all of which will be aggregated with small number suppression in line with the HES analysis guide) will be contained within written Word document reports, PowerPoint Presentations and potentially interactive R Shiny dashboards for use within BNSSG CCG and the wider BNSSG NHS-funded system (including acute hospitals, community and mental health providers, and GPs).
Results may also be used in research articles for peer reviewed academic journals and be presented at healthcare or academic conferences. For example, the M&A team has previously published results of local analytics work in academic journals (the Journal of the Operational Research Society, and Operations Research for Healthcare), and presented findings to groups including Bristol Health Partners (a collaboration between local NHS organisations and universities), the NHS Wales Modelling Collaborative, and the annual conference of the Operational Research Society, and the annual meeting of The Health Foundation, in order to share important practical results with the wider NHS and healthcare research community. Similarly, results may be shared with NHS colleagues through engagement with forums such as the NHS-R Community, the Association of Healthcare Analysts, and through sharing of reports on forums such as the NHS Future Collaboration message board and by informal correspondence with colleagues at NHS England/Improvement and other CCGs/ICSs.
Sharing with other CCGs
A number of distribution channels for such outputs are currently in various stages of maturation:
The NHS-R Community (a national project backed by the Health Foundation and NHS England/Improvement which brings analysts working with the statistical software together through conferences, workshops, regional networks and a website, with long term intentions to create a shared computer code repository accessible to NHS analysts and partner organisations). NHS Bristol, North Somerset and South Gloucestershire CCG is an active participant in this network and is running workshops at its forthcoming annual conference, and would anticipate doing the same at future events, featuring the outputs of the work completed using the HES data.
Local and regional NHS/healthcare analytics networks.
NHS Bristol, North Somerset and South Gloucestershire CCG is a leader in a local west of England analytics network being developed by Bristol Health Partners and a range of providers and planners from their own area, including some with cross-boundary responsibilities. Part of the purpose of this network is to establish communications between analysts in separate organisations so they can directly share expertise, analytical outputs and computer code. NHS Bristol, North Somerset and South Gloucestershire CCG is also leading work setting up links which will form the basis of an extended network involving neighboring CCG areas (for example with Gloucestershire CCG). In addition, NHS Bristol, North Somerset and South Gloucestershire CCG is working with regional networks in other areas, for example it is running workshops for the West Midlands analytical network on novel population segmentation methods it has developed, including sharing computer code to perform the analysis, and would envisage doing the same with the results of the work done with the HES data.
There are already close working relationships with the University of Bath Management School Centre for Healthcare Innovation and Improvement (where one of the team is a visiting research fellow) and the University of Bristol Population Health Sciences Institute and Elizabeth Blackwell Institute, as well as the NIHR South-West Applied Research Collaboration (ARC). NHS Bristol, North Somerset and South Gloucestershire CCG would be able to share relevant high level outputs of the HES work with academics working in partnership with NHS organisations on defined projects. Availability of usable real-world data is well established a major barrier to realising practical benefits from research projects in academic statistical modelling and operational research (acknowledged in the work of the national Plethora project for example, which was set up in part to bridge the gap between academic knowledge/technique generation and practical application of those outputs by healthcare analysts at the NHS coalface).
Dissemination of findings would also include posting of relevant results and outputs on the future NHS Collaboration platform, in addition to posting of relevant code, reusable output summary data, documentation, and (high level aggregate) data (with small number suppression) to an NHS BNSSG Analytics GitHub repository (subject to IG approval).
Publication of practical studies performed using the HES data in academic journals. This could include case studies of simulation projects carried out using the data, or specific statistical analyses. For example, the applicant is currently working on an investigation into the effect of day of week of hospital discharge on total length of stay, and is subsequent association with other factors such as readmission rates. These are live questions in local policy formulation and are equally relevant to other organisations.
All outputs will only contain aggregated data with small number suppression applied in line with the HES analysis guide.
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).
NHS Digital will provide HES APC (Admitted Patient Care), A&E (Accident and Emergency) and OP (Outpatient) data to BNSSG CCG, via NHS South Central and West Commissioning Support Unit (SCWCSU), which provides IT and database administration support services to the CCG. The data controller will be the BNSSG CCG, and they will also be the main data processor. SCWCSU will also be a data processor, but its activities will be restricted to download and storage of the data on behalf of BNSSG CCG. The CSU/CCG infrastructure is within the NHS’s secure N3 network and the HES data will be stored in a secure MS SQL Server data warehouse within that infrastructure. Access to that data will be restricted, through Microsoft Active Directory access control, solely to permanent staff members of BNSSG CCG - specifically the M&A team. SCWCSU will act only upon specific instruction from BNSSG CCG M&A on this project, and the data will be stored only at those addresses listed in the storage addresses section of this application. There will be no flow of data into NHS Digital. All substantive analysis and use of the record level data will be restricted to the BNSSG CCG M&A team - all of who are substantive employees of the organisation.
Data minimisation has been applied through restricting the timeframe of the data requested to the most recent three years only, by requesting only pseudonymised data, and by excluding those fields classified as “sensitive”. Further minimisation, such as filtering by age or geography or excluding specific data fields from the request, were considered but deemed incompatible with the purposes specified under “objective for processing” above.
The HES data will not be available to third parties and will not be taken out of BNSSG CCG offices. Record level data will not be shared outside the BNSSG CCG. Results of analysis will be at an aggregate level, and will be shared only at that level (in the form of graphs, summary statistics, and parameters to derived probability distributions), with small number suppression applied as per HES guidelines. It will not be possible to identify specific patients, clinicians or other individuals from these outputs.
The data will not be onwardly linked with any other record-level patient data. The narrative descriptions of coded data values in the HES extract (e.g. treatment function codes, administrative category codes etc.) may be looked up in the NHS Data Dictionary.
Data will relate to the whole of England, not just the registered population of BNSSG CCG – this is an explicit requirement of the project, as explained above in the “objective for processing” section.
Results of the analysis will be aggregated to service/pathway level, incorporating small number suppression as per the HES guidelines where necessary, and will not identify (or allow the identification of) specific patients, clinicians or other individuals.
