Medical school type and physician income

We wanted to determine whether the type of medical school attended--private US, public US, or foreign medical school--is associated with practice characteristics or incomes of physicians. Therefore, we used survey responses obtained during the 1990s from 10,436 actively practicing white male physicians who worked in one of 13 medical specialties and who graduated from a public US (5,702), private US (3,797), or international (937) medical school. We used linear regression modeling to determine the association between type of medical school attended and physicians' annual incomes after controlling for specialty, work hours, provider characteristics, and practice characteristics. We found that, for most specialties, international medical school graduates worked longer hours, were less likely to be board certified, had practiced medicine for fewer years, and were less likely to work in rural settings than US medical school graduates. After controlling for key variables, international medical school graduates' annual incomes were 2.6 percent higher (95% CI: 0.1%, 4.4%, p = .043) and public US medical school graduates' were 2.2 percent higher (95% CI: -0.9% -6.1%, p = 0.2) than private US medical school graduates' incomes. Because of their lower tuition expenses, international and public US medical school graduates may experience higher returns on educational investment than their counterparts who graduated from private US medical schools.
