Changes in health care utilization and associated costs after supportive housing placement by an urban community mental health center

Permanent supportive housing (PSH) for individuals experiencing homelessness and living with mental illness can reduce utilization of crisis care services and increase utilization of outpatient care, although the extent to which pre-housing utilization patterns influence post-housing utilization remains unclear. Therefore, pre- and post-housing health service utilization was examined in 80 individuals living with a chronic mental illness who were and were not utilizing health care services in the years pre- and post-housing. Overall, the proportion of tenants utilizing outpatient services, including outpatient behavioral health services, increased from pre- to post-housing. Tenants who did not use outpatient behavioral health services prior to housing were disproportionately less likely than their peers to use those services after being housed. Among tenants who utilized crisis care services prior to being housed, reductions were observed in the number of crisis care visits. Results suggest PSH leads to changes in health care utilization and associated costs.
