Private and public initiatives in health maintenance organizations.

Public policy controversies about the cost-containing potential of HMOs and the failures of many plans should not overshadow the fact that HMOs will be forces in the health care sector in the 1980s, largely as the result of increasing private investment. There is a large, stable segment of the prepaid industry that developed as a result of private sector and community concern long before the federal HMO Act of 1973, and it is their initiatives along with increasing investment activity by insurance companies and management companies in particular, that will serve as a base for consolidation and growth of HMO plans. HMOs have not proved to be the miraculous cost-containing mechanism of the future, but their impact will be felt even more for the changes they stimulate in the customary organizational forms, in financing, and in the role of business in health care.
