Inpatient hospitalizations and emergency service visits among participants in an Individual Placement and Support (IPS) model program.

Supported employment (SE) is considered an "evidence-based" practice for people with serious mental illness. We examined inpatient hospitalizations and emergency service visits among clients in a SE program based on the Individual Placement and Support (IPS) model in comparison to a propensity score matched group of clients who did not participate in IPS. A significant interaction showed that only IPS/SE clients who were also high in regular mental health services had fewer hospitalizations and emergency service visits than matched controls. The interaction effect was moderate, even when we controlled for client functioning. These findings provide support for the integration of mental health and vocational rehabilitation services, a key feature of evidence-based SE services.
