Medicare physician and hospital utilization and expenditure trends

Area of Science:

• Health Economics
• Healthcare Policy
• Medical Services Research

Background:

• The implementation of the Medicare prospective payment system (PPS) in 1983 marked a significant shift in healthcare reimbursement.
• Understanding the impact of PPS on healthcare utilization and expenditures is crucial for policy evaluation.

Purpose of the Study:

• To analyze the changes in Medicare patient care utilization patterns after the introduction of the prospective payment system.
• To examine the relationship between prospective payment system implementation and shifts in inpatient versus outpatient care and associated expenditures.

Main Methods:

• Analysis of Medicare utilization data from 1983-1987.
• Tracking inpatient hospital care trends.
• Monitoring fee-for-service utilization for physicians, noninstitutional suppliers, and outpatient facilities.

Main Results:

• A decline in inpatient hospital care utilization was observed immediately following Medicare PPS implementation (1983-86).
• Concurrently, there was an increase in fee-for-service utilization for physicians, noninstitutional suppliers, and outpatient facility care.
• Medicare expenditures for physicians, suppliers, and outpatient care rose in parallel with utilization changes.
• By 1987, inpatient care stabilized, while outpatient hospital care continued to increase.

Conclusions:

• The Medicare prospective payment system influenced a shift from inpatient to outpatient care settings.
• This shift was associated with increased utilization and expenditures in non-hospital-based services.
• Policy changes like PPS can lead to significant, measurable alterations in healthcare delivery and resource allocation.
