Primary-care--physician supply: policy analysis on the state level

Area of Science:

• Health Policy Analysis
• Physician Workforce Dynamics
• Systems Analysis in Healthcare

Background:

• Understanding the determinants of primary care physician supply is crucial for effective healthcare policy.
• Existing analyses often overlook key factors influencing physician workforce dynamics.
• State-level data is essential for targeted policy interventions.

Purpose of the Study:

• To present a systems analysis method for state-level policy analysis.
• To identify overlooked determinants of primary care physician supply and dynamics.
• To inform rational policy formulation for physician workforce planning.

Main Methods:

• Systems analysis approach incorporating interstate migration, physician origins, age distribution, and time delays.
• Development of a forecasting mathematical model with physician-aging, medical education, and migration subsystems.
• Utilized Virginia Board of Medicine archive database for data retrieval.

Main Results:

• Out-of-state migration is a critical factor, supplying approximately two-thirds of primary care physicians in Virginia.
• A significant age bulge in the physician population indicates a forthcoming increase in attrition over the next decade.
• Similar age distribution patterns were observed in other states, suggesting broader applicability.

Conclusions:

• The described method effectively reveals the mechanisms of physician workforce reproduction.
• The analysis can identify feasible policy goals and inform evidence-based decision-making.
• This approach is adaptable for policy research in any state.
