The national health service corps and medicaid inpatient care: Experience in a southern state

Background: Since 1970, the National Health Service Corps (NHSC) has worked to increase primary care access among underserved groups. This study examined whether NHSC alumni physicians were likely to treat a high proportion of Medicaid patients in their practices. Methods: Using licensure files and hospital discharge data, we identified all physicians practicing in South Carolina who attended at least one discharge in 1998, excluding physicians who graduated before 1969, residents, and current NHSC-obligated physicians. The outcome studied was ranking in the highest quartile for Medicaid participation. Results: Former NHSC participants, after adjustment for personal characteristics, education, and specialty, were nearly twice as likely to fall into the category of high Medicaid participation. NHSC physicians were more likely to practice in community health centers and to locate in areas with a health professions shortage and counties with high percentages of minorities and people living in poverty. Conclusion: NHSC alumni make career choices leading them to serve low-income patients.
