Medicare physician and hospital utilization and expenditure trends

Abstract

During the period 1983-86, the period directly following implementation of the Medicare prospective payment system, inpatient hospital care declined. Concurrently, fee-for-service utilization rates for physicians and other noninstitutional suppliers of medical goods and services and for outpatient facility care rose. Medicare expenditures for physicians and other suppliers and for outpatient facility care paralleled changes in utilization. In 1987, the proportion of Medicare patients receiving inpatient hospital care stabilized, but the proportion receiving outpatient hospital care continued to increase.
