Using the interRAI brief mental health screener to identify persons with mental disorders having repeat contact with police

Abstract

Repeat contacts between persons with serious mental disorder (PSMD) and police officers are costly to both police services and hospitals in terms of service utilization and can be viewed as a direct indicator of unmet needs and gaps in service provision. The intent of the current study was to examine the demographic and clinical characteristics of PSMD who had repeat contact with police officers in London, Ontario from 2016 to 2019 using data collected using the interRAI Brief Mental Health Screener (BMHS). Negative binomial regression was used on a sample of 4143 cases to develop a model predictive of repeat police contacts. The most parsimonious model predicting police contact based on items on the BMHS included age, command hallucinations, lack of insight, verbal abuse, known to possess weapons and family, friends and caregivers expressing concern over the possibility of self harm. Delusions were also independently significantly associated with repeat encounters. Unique to this study is the observation that possessing a weapon in the past 12 months was included in the predictive model. The results of the study add to the sparse research devoted to identifying the characteristics of PSMD who have repeat contact with police officers. Recommendations include integrating the findings into police training to ensure police officers flag those who have the potential for repeat encounters and refer them to appropriate community mental health service providers for proactive outreach services.
