THE CHALLENGE OF MANAGED CARE AND MANAGED COMPETITION

Payment for health care in the United States changed rapidly during the 1980s, with the changes often identified by three-letter acronyms such as HMO, PPO, DRG, and RVS (health maintenance organization, preferred provider organization, diagnosis-related group, and relative value system). Changes are likely to be even more rapid and fundamental in the next few years. ''Managed care'' and ''managed competition'' are the principal terms being used to describe these pending changes. In this paper, we briefly present the problems that have led to changes, the changes that have occurred, the changes likely in the future, the implications of these changes for radiologists, and how radiologists can respond most effectively. We concentrate on the implications of changes for radiologists and on how radiologists can respond effectively.
