Longitudinal record linked analysis of an Assertive Community Treatment programme in a suburban mental health hospital: Emergency department presentations, hospital admissions and bed days.

Abstract Purpose This study aimed to objectively assess a long-term Assertive Community Treatment (ACT) programme run by a suburban mental health hospital in Western Australia. The study examined the programme by tracking Emergency Department (ED) presentations, hospital admissions and length of hospital stays (bed days) of people with severe mental illness who entered the programme. Methods Between January 2008 - June 2019, 160 clients who attended the hospital had presentation and admission activities assessed at two time periods 1) PRE - the period from each client’s first engagement with the mental health service up to their entering the service’s ACT programme, and 2) DURING – which is the time that each client spent engaged in that ACT programme. Results No difference was found between ED presentations before the ACT programme as compared to during the ACT programme. Voluntary mental health hospital admissions were significantly lower during the programme than before the programme, but no difference was found for involuntary mental health hospital admissions. Both voluntary and involuntary hospital stays, however, showed a significant reduction in bed days for clients during their time in the ACT programme. Conclusion This data shows mixed support for the continued use of the ACT programme at suburban mental health services. While ED presentations and involuntary admissions remained the same, the reduction in voluntary hospital admissions and hospital bed days suggests that the increased provision of outpatient and home care through ACT is working to support clients in the community keeping them out of more restrictive hospital settings.
