The future supply of physicians

Area of Science:

• Health Services Research
• Medical Workforce Planning
• Health Policy Analysis

Background:

• Historical policies, including the Flexner Report and American Medical Association initiatives, have shaped U.S. physician supply.
• Medicare, Medicaid, and immigration law changes have impacted the number of physicians, including international medical graduates (IMGs).
• Past forecasts, like the 1981 GMENAC Report, predicted physician oversupply, with limited response from the medical community.

Purpose of the Study:

• To analyze historical policy positions influencing U.S. physician supply.
• To evaluate current policy recommendations for addressing physician oversupply.
• To inform contemporary policymakers on managing physician workforce dynamics.

Main Methods:

• Historical policy analysis of medical education and workforce regulations.
• Review of factors affecting physician supply, including immigration and specialty distribution.
• Evaluation of four policy recommendations for physician oversupply management.

Main Results:

• Market-based solutions are unlikely to effectively control physician supply.
• Reducing international medical graduate (IMG) inflow will have minimal impact on physician oversupply.
• Closure of U.S. medical schools is improbable due to strong opposing forces.
• The future ratio of primary care to specialist physicians remains uncertain, with potential for continued specialist income growth.

Conclusions:

• Policy interventions are necessary to manage physician supply, as market forces are insufficient.
• Current policies and trends suggest continued growth in physician numbers, particularly specialists.
• Addressing physician oversupply requires a comprehensive strategy beyond market adjustments or limiting IMGs.
