Mapping same day, urgent and emergency care services across the UK: a mixed methods study protocol.

introductionIn the UK, a range of services provide same day, urgent and emergency care (UEC). Urgent medical needs can be addressed through pharmacy services, same day general practice (GP) appointments, phone or online triage services, out-of-hours GP appointments and urgent treatment centres (or equivalents). For emergency medical needs, patients can access emergency departments (EDs) and ambulance services. These services are highly vulnerable to excessive strain due to rising, unpredictable demand and limitations in patient flow across the system. The workforce operates in time-critical situations, often with limited resources, which can lead to staff burnout, low job satisfaction and retention and poor health. The organisation of services and their workforce continues to evolve in response to local and national pressures and varies considerably across the UK, where there are four distinct, publicly funded healthcare systems managed separately in each country. This makes it difficult to describe and compare services within and across regions and understand the impact of workforce organisation on service delivery, staff well-being and patient care. This study aims to develop a comprehensive understanding of the range and types of UK UEC services, the relative experiences of the workforce and the available workforce data. METHODS AND ANALYSIS: This mixed-methods study includes two components, integrated through an explanatory sequential design. Study 1 will use data on NHS service availability and direct enquiry to map UEC services and populate a structured database, which will facilitate the generation of a UEC typology of the range and types of services and regional variation across the UK. Multiple case studies will be conducted in a subset of services using qualitative interviews (n=136-220) with service leaders (n=3-5), workforce (n=10-12), and patients or carers (n=4-5), as well as document analysis where relevant, in each service of interest (n=8-10). Study 2 will create a metadata catalogue of workforce data and produce descriptive summaries of key metrics (eg, staffing levels and skill mix). The study will be supported by our Community Inclusion and Engagement (CIE) panel and Patient and Public Advisory Group (PPAG) to ensure relevance, inclusivity and impact. ETHICS AND DISSEMINATION: This study received ethical approval from Yorkshire and The Humber - Sheffield Research Ethics Committee (04/08/2025, IRAS ID: 357276, REC Reference: 25/YH/0125) and HRA and Health and Care Research Wales approval (12/08/2025). Data collection poses minimal risk, informed consent will be obtained, and participants may withdraw at any time. Dissemination will follow knowledge mobilisation principles to maximise impact. We will build on our existing networks and work with our CIE panel and PPAG to tailor study outputs to different audiences. The outputs will improve understanding of the variation in how UEC services and workforces are organised across the UK, as well as the type and format of available workforce data, and provide benchmarks for future research.
