A Controlled Trial of the Effect of a Prepaid Group Practice on the Utilization of Medical ServicesThis report compares people's utilization of health services under a prepaid group practice plan with that under fee-for-service. The work was undertaken as a part of the Rand Health Insurance Experiment, a large-scale social experiment designed to investigate the effects of health insurance plans on utilization of health services and health status. Other Rand reports based on this experiment also deal with the demand for health services: J. P. Newhouse, W. G. Manning, C. N. Morris, et al., Some Interim Results from a Controlled Trial of Cost Sharing in Health Insurance, R-2847-HHS, January 1982; N. Duan, W. G. Manning, C. N. Morris, and J. P. Newhouse, A Comparison of Alternative Models for the Demand for Medical Care, R-2754-HHS, January 1982; E. B. Keeler, J. E. Rolph, N. Duan, et al., The Demand for Episodes of Medical Treatment: Interim Results from the Health Insurance Experiment, R-2829-HHS, December 1982. These reports discuss the initial fee-for-service results of the study and discuss the statistical problems to be faced in estimating the demand for medical care. The present report should be of interest to persons studying the use of medical services and the organization of medical care. An abridged version of this report was published in the New England Journal of Medicine, June 7, 1984 |
