Costs of the police service and mental healthcare pathways experienced by individuals with enduring mental health needs

BACKGROUND: Substantial policy, communication and operational gaps exist between mental health services and the police for individuals with enduring mental health needs. AIMS: To map and cost pathways through mental health and police services, and to model the cost impact of implementing key policy recommendations. METHOD: Within a case-linkage study, we estimated 1-year individual-level healthcare and policing costs. Using decision modelling, we then estimated the potential impact on costs of three recommended service enhancements: street triage, Mental Health Act assessments for all Section 136 detainees and outreach custody link workers. RESULTS: Under current care, average 1-year mental health and police costs were £10 812 and £4552 per individual respectively (n = 55). The cost per police incident was £522. Models suggested that each service enhancement would alter per incident costs by between -8% and +6%. CONCLUSIONS: Recommended enhancements to care pathways only marginally increase individual-level costs.
