Summary

NIHR PSRC dataset of 5,081 patients aged 65+ (2024-25), with demographics, symptoms, vital signs, tests, treatments, ward activity, discharge outcomes, readmissions and mortality to support analysis of Medical Same Day Emergency Care pathways.

Documentation

Medical Same Day Emergency Care (SMDEC) services review almost half of all unplanned attendances requiring medical review. Activity has risen sharply, with monthly MSDEC admissions increasing by up to 160 percent in the past year. Patients present with a wide range of conditions and follow varied diagnostic pathways. Many require further investigations such as CT or MRI or assessment by specialty services which can lead to long waits or return visits. There are currently no agreed criteria for MSDEC patient selection. To support research into these pathways, the NIHR PSRC and PIONEER have created a dataset of MSDEC activity. There are 5,081 patients included who are aged 65+ years and older. The dataset includes detailed demographics, symptoms, comorbidities, vital signs, investigations, imaging requests, specialty input, treatments, ward movement, discharge decisions, readmissions and mortality. It provides a comprehensive view of how patients move through MSDEC and the resources they use. The dataset enables analysis of variation, delays and predictors of outcomes in Same Day Emergency Care. 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 (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. 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 build and run. Consultancy with clinical, patient & end-user and purchaser access/ support. Support for regulatory requirements. Cohort discovery. Data-driven trials and “fast screen” services to assess population size.

Patient pathway description

Data is representative of the multi-ethnicity population within the West Midlands (42% non white). Data includes all patients admitted during this timeframe, with National data Opt Outs applied, and therefore is representative of admissions to secondary care. Data focuses on in-patient stay in hospital during the acute episode but can be supplemented on request to include previous and subsequent hospital contacts (including outpatient appointments) and ambulance, 111, 999 data.

Access service description

Trusted Research Environments (TRE) are built using Microsoft Azure services and hosted in the UK to provide research teams a safe, secure and agile environment which allows users to quickly analyse, interpret and form an enriched view of primary care information through a range of integrated datasets.

Health data collated from multiple sources is ingested into a secure data lake which will then allow subsets of data to be made available to research teams on approval of a data request. Once approved a customer specific TRE is made available with a standard set of leading analytical tools from Microsoft including Azure Databricks, Azure Machine Learning, Azure SQL and Azure Synapse (for large-scale data warehouses). Specific tools can be provided at an additional cost over the standard platform data access charge and the PIONEER team will work with you to determine your exact needs.

Access to the TRE is managed using the latest virtual desktop technology to provide a safe and secure end-user experience. By utilising leading edge design PIONEER are able to create TREs rapidly to enable us to service any customer requirement.
