Physician inputs, outputs, and productivity, 1976-1986.

Area of Science:

• Health economics
• Physician workforce trends
• Healthcare policy

Background:

• The number of physicians has increased over the past decade.
• Physician practice inputs and patient care outputs are key indicators of healthcare system performance.
• Understanding productivity trends is crucial for healthcare policy and cost management.

Purpose of the Study:

• To analyze trends in physician practice inputs, patient care outputs, and productivity over the last ten years.
• To investigate the relationship between physician supply, patient access, and intensity of care.
• To evaluate whether observed trends align with assumptions of productivity gains in Medicare fee updates.

Main Methods:

• Analysis of aggregate data on physician practice inputs and patient care outputs.
• Examination of trends in total patient contacts and physician time per visit.
• Assessment of changes in the intensity of medical services provided.

Main Results:

• Increased physician numbers have not improved population access (total patient contacts).
• Physician time and medical services per visit have increased, reflecting greater care intensity, not declining productivity.
• Physician productivity in delivering medical services has remained stagnant over the past decade.
• Observed trends are inconsistent with Medicare fee updates that presume productivity improvements.

Conclusions:

• Stagnant physician productivity, coupled with increased care intensity, may contribute to rapid healthcare fee inflation.
• Current healthcare policy assumptions regarding physician productivity gains may not reflect actual practice trends.
• Further research is needed to understand the drivers of care intensity and its impact on healthcare costs.
