RESUMEN
The authors have reviewed the present system of graduate medical education, including independent, affiliated, and integrated residency training programs. Advantages and disadvantages are considered in light of recent changes in health-care delivery systems. Structure, historical development, present status, and limitations of the programs are discussed. Personnel resources of the residency program are classified as United States citizens and non-citizens, American medical school graduates, United States citizen graduates of foreign medical schools, and alien foreign medical school graduates, and their different educational backgrounds are compared. Financial aspects of these programs are considered, and the need to increase university control over residency programs, especially in multi-institutional affiliated residency training programs is discussed. The authors recommend upgrading the status of residents from that of student to that of full-fledged medical doctor with concomitant authority and responsibility.
