Typology of psychiatric emergency services in the United Kingdom: a narrative literature review

Abstract

Abstract Background Mental health crisis requiring emergency access to psychiatric service can occur at any time. Psychiatric Emergency Service (PES) is described as one that provides an immediate response to an individual in crisis within the first 24 h. Presently, several types of PESs are available in the United Kingdom (UK) with the aim of providing prompt and effective assessment and management of patients. Therefore, this study aims to provide a detailed narrative literature review of the various types of Psychiatric Emergency Service (PES) currently available in the UK. Method Electronic search of five key databases (MEDLINE, PsychINFO, EMBASE, AMED and PUBMED) was conducted. Studies were included if it described a mental health service in the UK that provides immediate response in mental health crisis within the first 24 h. Excluded studies did not describe a PES, non-English, and were not conducted in UK. Results Nine types of PESs were found. Amongst the 9 services, more papers described crisis resolution home treatment. Majority of the papers reported services within England than other countries within the UK. Conclusion All types of PESs were described as beneficial, particularly to mental health service users, but not without some shortcomings. There is a need to continue carrying out methodological research that evaluate impact, cost-effectiveness as well as identify methods of optimising the beneficial outcomes of the various types of PESs. This may help inform researchers, policy makers and commissioners, service users and carers, service providers and many more on how to ensure current and future PESs meet the needs as well as aid recovery during crisis.
