Evaluation of the Colorado Clincial Psychology/Expanded Mental Health Benefits Experiment. Volume V: Impact of the Experiment on the Use, Cost, and Delivery of Medicare Services

摘要

The Colorado Clinical Psychology/Expanded Mental Health Benefits Experiment tested two alterations in the Medicare Program: (1) decreasing the copayment rate for outpatient mental health services from 50% to 20%, and (2) recognizing clinical psychologists as independent practitioners. The experiment conducted from October 1976 to December 1978, randomly assigned Medicare beneficiaries to four groups, representing the combinations of experimental and standard benefits. Volume V analyzes the effect of the experiment on the use, cost, and delivery of medical and mental health services.
