The authors propose a link between primary care graduate medical education and care for the underserved in community health centers, where expansion will be necessary for the anticipated increase in Medicaid and insured patients. This can be achieved by establishing primary care teaching health centers in expanded community health centers, which have established a patient-centered medical home practice environment. Residents would receive their final year of training in these centers, and then have the incentive of National Health Service Corps debt repayment if they subsequently practice in an underserved area.
