This report describes recent trends in the international migration of doctors and nurses in OECD countries. Over the past decade, the number of doctors and nurses has increased in many OECD countries, and foreign-born and foreign-trained doctors and nurses have contributed to a significant extent. New in-depth analysis of the internationalisation of medical education shows that in some countries (e.g. Israel, Norway, Sweden and the United States) a large and growing number of foreign-trained doctors are people born in these countries who obtained their first medical degree abroad before coming back. The report includes four case studies on the internationalisation of medical education in Europe (France, Ireland, Poland and Romania) as well as a case study on the integration of foreign-trained doctors in Canada.
