Examining the need for a high level of therapeutic security at a regional forensic mental health service in Aotearoa New Zealand.

The ceiling of therapeutic security in Aotearoa New Zealand is medium security. The aim of this study is to identify and characterise a putative cohort of high-secure patients at a medium-secure regional forensic mental health service. A retrospective review of all admissions to a specific service was conducted over 3.75 years. The Dangerousness Understanding, Recovery and Urgency Manual, Triage Security Scale (DUNDRUM-1) was used to identify patients with high-secure care needs. A multiple logistic regression analysis was used to identify the local needs of this cohort. We found a significant incidence (an admission every 55 days) and prevalence (11%) of mixed-gendered and culturally diverse patients with high-secure care needs. The cohort had a high prevalence of psychosis and violent offences, and relatively short length of stay. There is also an indication that the cohort was subject to more restrictive practice. A solution is proposed to meet the needs of this cohort.
