This is the 13th report prepared by the American Academy of Family Physicians (AAFP) on the percentage of each US medical school's graduates entering family practice residency programs. Approximately 12.3% of the 15,564 medical school graduates between July 1992 and June 1993 were first-year family practice residents in October 1993, compared with 10.8% the previous year. This is the highest percentage since 1983-1984. Medical school graduates from publicly funded medical schools were more than twice as likely to be first-year family practice residents in October 1993 as were residents from privately funded schools, 15.9% compared with 7.1%. The Mountain region again reported the highest percentage of medical school graduates who were first-year residents in family practice programs in October 1993 at 19.1%; the Middle Atlantic and New England regions continued with the lowest percentages at 7.7% and 6.6%, respectively. At least one in four graduates from nine medical schools during the reporting period was in a family practice residency program in October 1993; only two medical schools had this distinction in 1992. Approximately one in two medical school graduates entering a family practice residency program as first-year residents in October 1993 entered a program in the same state where they graduated from medical school. The percentages for each medical school have varied substantially from year to year since the AAFP began reporting this information. The average percentage for each medical school for the last 3 years is reported.(ABSTRACT TRUNCATED AT 250 WORDS)
