Intervention to reduce inpatient psychiatric admission in a metropolitan city.

When psychiatric hospitalization is over-used, it represents a financial drain and failure of care. We evaluated implementation and cessation of transporting people medically certified for psychiatric hospitalization to a central psychiatric emergency service for management and re-evaluation of hospitalization need. After implementation, the hospitalization rate declined 89% for 346 transported patients; only four of the nonhospitalized patients presented in crisis again in the next 30 days. Following cessation, the hospitalization rate jumped 59% compared to the preceding year. Costs declined 78.7% per diverted patient. The findings indicate that it is possible to reduce hospitalization and costs, and maintain quality care.
