What is the existing evidence base for adult medical same day emergency care in UK NHS hospitals? A scoping review protocol.

Objectives: Same day emergency care (SDEC) is a new model of care, which has emerged over the past 5 years, building on prior ambulatory care services. The National Health Service (NHS) England National Strategy for SDEC suggests SDEC can meet local health needs by providing alternatives to emergency department attendance or hospital admission, for people with an urgent healthcare need, beyond the limited scope of an urgent treatment centre. This review focuses on acute medical SDEC, as medical patients represent a significant proportion of emergency admissions. The planned scoping review aims to map the existing evidence base.

Methods And Analysis: This is a protocol for a scoping review to be conducted in accordance with the format of the Joanna Briggs Institute (JBI) methodology for scoping reviews. The databases to be searched will include EMBASE, MEDLINE and CINAHL, via EBSCOhost. Sources of unpublished studies, policies and grey literature will include Google Scholar, the Cochrane Library, TRIP database, ProQuest Dissertations and Theses Open, and the Health Management Information Consortium. Papers relating to acute medicine adult patients attending NHS SDEC services in the UK will be included. International papers will be excluded, as will those over 5 years old, and those where full text is not available. The results of the search and study inclusion/exclusion process will be reported and presented in a Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) flow diagram. Data will be extracted from papers included in the scoping review by two reviewers, using a JBI data extraction tool. Any differences of opinion will be discussed until consensus is reached. If needed, a third reviewer will be asked to join the review team to achieve consensus. Data and themes extracted will be summarised and presented in tables. A narrative thematic summary will accompany the presented results, describing how the results relate to the review objective. Literature gaps will be identified and recommendations for future research made.

Ethics And Dissemination: There is no requirement for ethical approval for this scoping review. On completion, it will be published in a peer-reviewed academic journal and presented at a conference.
