Patient Protection and Affordable Care Act: promise and peril for primary care

The Patient Protection and Affordable Care Act (PPACA) of 2010 brings both promise and peril for primary care. This Act has the potential to reestablish primary care as the foundation of U.S. health care delivery. The legislation authorizes specific programs to stabilize and expand the primary care physician workforce, provides an immediate 10% increase in primary care physician payment, creates an opportunity to correct the skewed resource-based relative value scale, and supports innovation in primary care practice. Nevertheless, the peril is that the PPACA initiatives may not alter the current trend toward an increasingly specialized physician workforce. To realize the potential for the PPACA to achieve a more equitable balance between generalist and specialist physicians, all primary care advocates must actively engage in the long rebuilding process.
