This dataset forms part of ADMISSION, the NIHR and UKRI funded programme of work to better understand and to design healthcare services which are better able to care for patients with multiple long term conditions.

This dataset includes >70,000 adult patients who were acutely admitted to hospital. It includes longitudinal and detailed data for these people over 10-years, designed to trace the accrual, progression and impact of multiple co-morbidities as well as acute health care use and outcomes.

The dataset contains highly granular data regarding patient demographics and the specific co-morbidities associated with each patient, categorised according to ICD-10 codes. It provides a structured sequence of data related to the acute care and inpatient process, capturing critical timings, acuity, medications, laboratory results, observations, readmissions, and mortality rates.

Geography: The West Midlands (WM) has a population of 6 million & includes a diverse ethnic & socio-economic mix. UHB is one of the largest NHS Trusts in England, providing direct acute services & specialist care across four hospital sites, with 2.2 million patient episodes per year, 2750 beds & > 120 ITU bed capacity. UHB runs a fully electronic healthcare record (EHR) (PICS; Birmingham Systems), a shared primary & secondary care record (Your Care Connected) & a patient portal “My Health”.

Data set availability: Data access is available via the PIONEER Hub for projects which will benefit the public or patients. This can be by developing a new understanding of disease, by providing insights into how to improve care, or by developing new models, tools, treatments, or care processes. Data access can be provided to NHS, academic, commercial, policy and third sector organisations. Applications from SMEs are welcome. Data access must reference ADMISSION and the papers which describe this resource. There is a single data access process, with public oversight provided by our public review committee, the Data Trust Committee. Contact pioneer@uhb.nhs.uk or visit www.pioneerdatahub.co.uk for more details.

Available supplementary data: Matched controls; ambulance and community data. Unstructured data (images). We can provide the dataset in OMOP and other common data models and can build synthetic data to meet bespoke requirements.

Available supplementary support: Analytics, model build, validation & refinement; A.I. support. Data partner support for ETL (extract, transform & load) processes. Bespoke and “off the shelf” Trusted Research Environment (TRE) build and run. Consultancy with clinical, patient & end-user and purchaser access/ support. Support for regulatory requirements.
