Background There has been substantial immigration of physiciansto developed countries, much of it coming from lower-incomecountries. Although the recipient nations and the immigratingphysicians benefit from this migration, less developed countrieslose important health capabilities as a result of the loss ofphysicians.
Methods Data on the countries of origin, based on countriesof medical education, of international medical graduates practicingin the United States, the United Kingdom, Canada, and Australiawere obtained from sources in the respective countries and analyzedseparately and in aggregate. With the use of World Health Organizationdata, I computed an emigration factor for the countries of originof the immigrant physicians to provide a relative measure ofthe number of physicians lost by emigration.
Results International medical graduates constitute between 23and 28 percent of physicians in the United States, the UnitedKingdom, Canada, and Australia, and lower-income countries supplybetween 40 and 75 percent of these international medical graduates.India, the Philippines, and Pakistan are the leading sourcesof international medical graduates. The United Kingdom, Canada,and Australia draw a substantial number of physicians from SouthAfrica, and the United States draws very heavily from the Philippines.Nine of the 20 countries with the highest emigration factorsare in sub-Saharan Africa or the Caribbean.
Conclusions Reliance on international medical graduates in theUnited States, the United Kingdom, Canada, and Australia isreducing the supply of physicians in many lower-income countries.
