Understanding volume: a Medicare primer

Area of Science:

• Health economics
• Medical services research
• Healthcare policy analysis

Background:

• Physician costs significantly increased during the 1970s and 1980s.
• Understanding the drivers of these cost escalations is crucial for healthcare policy.

Purpose of the Study:

• To determine whether increased service volume or higher physician fees were the primary drivers of rising healthcare costs.
• To identify the specific areas of medical practice contributing to cost growth.

Main Methods:

• Analysis of healthcare expenditure data from the 1970s and 1980s.
• Examination of trends in physician service utilization and fee structures.
• Statistical modeling to attribute cost changes to volume versus price.

Main Results:

• Increased volume of medical services, not real fee increases, was the main factor driving physician costs up.
• Growth in utilization patterns across various medical specialties contributed to overall cost escalation.

Conclusions:

• Policy interventions should focus on managing the utilization of healthcare services to control costs.
• Future research should investigate the specific factors driving the growth in service volume.
