As our population ages, it is increasingly common for people presenting to hospital with critical illness to be older. Tools to identify people who may respond well to critical care interventions have not been optimised for older people and although age is a factor associated with poorer outcomes following admission to critical care; frailty and multimorbidity are also likely to be important.

This is a highly granular dataset of 8,656 critical care admissions for patients aged 65 and over, curated by the NIHR Birmingham Biomedical Research Centre Infection and Acute Care Theme in collaboration with PIONEER. It includes initial presentation, symptoms, and pre-calculated severity scores (SAPS, APACHE, SOFA). Data covers demographics, serial physiology, ventilatory parameters, investigations, treatments (drug, dose, route), diagnostic codes (ICD-10 & SNOMED-CT), and outcomes, with follow-up for one year. It can be supplemented with imaging (results and images) and linked to ambulance conveyance and community outcomes. Admissions span from 01-01-2017 to 01-03-2023. A full dataset for all ages is also available.

Geography: The West Midlands 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 (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. 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.
