Effect of Full-Service Partnerships on Homelessness, Use and Costs of Mental Health Services, and Quality of Life among Adults with Serious Mental Illness

Chronically homeless adults with severe mental illness are heavy users of costly inpatient and emergency psychiatric services. Full-service partnerships (FSPs) provide housing and engage clients in treatment. A quasi-experimental, difference-in-difference design with a propensity score–matched control group was used to compare mental health service use and costs of FSP with public mental health services. Recovery outcomes were compared before and after services use, and quality of life was compared cross-sectionally. Participation in an FSP was associated with substantial increases in outpatient services and days spent in housing. Reductions in costs of inpatient/emergency and justice system services offset 82% of the cost of the FSP.
