Hospital role on decline.

The era of hospital dominance of the health care field has ended. The new day will belong to insurers and payers. Health maintenance organizations will become the primary actor on the health care scene. If PPOs are added to HMOs, and by 1990 most PPOs will look like HMOs, 70 percent of the U.S. population will be enrolled in such plans. By that time, at least 10 percent of the nation's hospitals will have disappeared.
