Capitated Assertive Community Treatment Program Savings: System Implications

Daniel Chandler and Gary Spicer

September 2002

In a California county of one million people, 4% of all clients served in 1994 were found to use 38% of publicly funded mental health services. A controlled experiment was designed to test whether a capitated Assertive Community Treatment (ACT) program could produce outcomes that were equivalent or better than “usual services” for a subset of very high-utilizing clients while reducing costs. Results showed that major challenges in using an ACT program for cost reduction were successfully met. Costs over all 4 years were substantially lower for the experimental group than for a randomly assigned comparison group.
