Secondary mental health service utilisation following emergency department contact for suicidal behaviour: A systematic review.

OBJECTIVE: Engagement with secondary mental health services after an emergency department presentation with suicidal behaviours may be an important strategy for reducing the risk of repeat attempts. Our aim was to examine secondary mental health service contact following a presentation to emergency department with suicidal behaviours. METHODS: A systematic review of papers published between 2000 and 2020 was undertaken. This identified 56 papers relating to 47 primary studies. Data were extracted and summarised separately by age group: (1) young people, (2) older adults and (3) adults and studies with participants of 'all ages'. RESULTS: Studies in young people (n = 13) showed, on average, 44.8% were referred and 33.7% had contact with secondary mental health services within 4 weeks of emergency department discharge. In comparison, in adult/all ages studies (n = 34), on average, 27.1% were referred to and 26.2% had mental health service contact within 4 weeks. Only three studies presented data on contact with mental health services for older adults, and proportions ranged from 49.0% to 86.0%. CONCLUSION: This review highlights poor utilisation of secondary mental health service following emergency department presentation for suicidal behaviours, and further research is needed to identify the reasons for this. Crucially, this information could assist in the allocation of resources to facilitate the timely implementation of suicide prevention services.
