A model for a comparative cost-effectiveness evaluation of two mental health partial care programs.

This study provides a model for comparing the cost-effectiveness of two mental health programs. The example cited examines the cost-effectiveness of a hospital-based and a community-based partial care program. Using each group as its own control, the authors compare patients' use of inpatient hospitalisation and emergency room services during one year prior to and one year subsequent to first admission in day care. In both day care programs, patients substantially reduced their number of inpatient admissions and days. Neither program, however, showed a significant decrease in patients' use of the emergency room. Reflecting the substantially lower costs of the community-based program, the benefit-cost and cost-effectiveness ratios were significantly better in the community-based program than in the hospital-based program. Based on this evidence the authors conclude that the lower-cost, equally effective community-based program should be carefully considered as an alternative for more partial care patients.
