Seventy-two patients who received five years of intensive case management services were transferred into mainstream community mental health center services with a much higher patient-to-staff ratio. At the end of a two-year follow-up, 91 percent of the patients were still receiving treatment. Compared with the previous five years, hospitalizations during the follow-up period increased, but not significantly so. Contacts with mainstream CMHC services increased significantly. Overall costs in constant 1979 dollars showed a nonsignificant decrease, dropping by about $1,500 per patient per year. The staff time and resources gained by the programmatic changes were used to treat a larger number of chronic patients seeking services.
