Background In the United States, the Affordable Care Act (ACA) will expand insurance coverage to an additional 34 million people. This study projects the number of primary care physicians that will be needed to address expected increases in use, including increases due to insurance expansion.
What This Study Found Researchers project the United States will need 52,000 additional primary care physicians by 2025 - a 25% increase in the current workforce - to address the expected increases in demand due to population growth, aging, and insurance expansion. Population growth will be the single greatest driver of increased primary care utilization, requiring approximately 33,000 additional primary care physicians by 2025, while 10,000 additional physicians will be needed to accommodate population aging. Insurance expansion will require approximately 8,000 additional primary care physicians, a 3% increase in the current workforce.
Implications
- Given the current maldistribution of physicians, increased productivity will not always be sufficient to meet the increased demand for primary care. As a result, the authors suggest, policy options that increase the size of the primary care workforce without addressing distribution will be less successful.
