Health spending trends in the 1980's: adjusting to financial incentives.

Health expenditure growth is projected to moderate considerably during 1983-90, reaching $660 billion in 1990 and consuming over 11 percent of the gross national product. During 1973-83, spending for health care more than tripled, increasing from $103 billion to $355 billion and moving from 7.8 percent to 10.8 percent of the gross national product. Government spending for health care is projected to reach $284 billion by 1990, with the Federal Government paying 73 percent. The Medicare Prospective Payment System, private sector initiatives, and State and local government actions are providing incentives to substantially increase competition and cost effectiveness in health care provision.
