Association of Family Medicine Interest at Matriculation to Medical School and FMIG Participation With Eventual Practice as a Family Physician.

BACKGROUND AND OBJECTIVES: An adequate family medicine workforce is needed to improve health and health care outcomes in the United States, yet few medical students in the US become family physicians. Indicators of family medicine interest upon medical school matriculation exist. Family medicine interest groups (FMIGs) may influence student choice. This study examines the association of FMIG participation with various matriculation interest indicators to predict which students go on to become family physicians.

METHODS: The American Medical Association Masterfile was used to identify the practice specialty of 601 graduates of the University of Washington School of Medicine who matriculated between 2003 and 2007. Graduates' scores on the Family Medicine Interest Survey (FMIS) and whether a student listed family medicine as their top choice upon matriculation along with FMIG participation and demographic characteristics were used in a binary logistic regression model to predict eventual practice. The model output was used to calculate odds ratios and predicted probabilities of family medicine practice given initial family medicine interest and FMIG participation.

RESULTS: FMIG participation was associated with higher odds ratios and increased predicted probability of becoming a family physician regardless of initial interest although the magnitude of the difference varied. FMIG participants who listed family medicine as their top specialty had a 68% predicted probability of entering family medicine compared to 8% probability if they did not list family medicine first and did not participate in FMIG. FMIG participation was associated with odds ratios between 3.27-4.19 for entering family medicine regardless of FMIS score.

CONCLUSIONS: Among University of Washington students with family medicine as their top specialty choice upon matriculation, FMIG participation was associated with higher odds of entering the specialty. The same was true, although to a lesser degree, for students who had a high score on the FMIS.
