Close to half of all internal medicine physicians practicing in the United States were born in another country, according to a new study reported by Medscape.
The finding draws attention to the extent to which the American healthcare system depends on foreign-born medical professionals, particularly in a specialty that serves as a backbone of primary and hospital-based care. Internal medicine doctors treat a wide range of adult illnesses and are often the first point of contact for patients with complex or chronic conditions.
The study does not examine the reasons behind the trend in detail, but the pattern has been building for decades. The United States has long relied on international medical graduates to fill residency positions and staff hospitals, particularly in underserved areas where American-trained physicians are less likely to practice.
The findings come at a time when federal immigration policy is under intense scrutiny, and healthcare administrators have raised concerns about restrictions that could affect the pipeline of foreign-born medical professionals entering the country. Any significant reduction in that pipeline would be felt most acutely in specialties and regions already facing shortages.
Internal medicine is among the specialties with the highest proportion of international medical graduates. Foreign-born physicians are also disproportionately represented in other fields including nephrology, infectious disease, and geriatrics, areas that often struggle to attract enough domestically trained doctors.
The study's findings reinforce long-standing data showing that immigrant physicians play a critical role in keeping the American healthcare system functional, particularly in rural communities and safety-net hospitals that serve low-income patients.
No specific policy recommendations were attached to the study, but the data arrives at a moment when the composition and sustainability of the physician workforce is a live political and public health question.
