Impact of Medical School Experience on Attrition From General Surgery Residency

Medical school experience informs the decision to pursue graduate surgical education. However, it is possible that inadequate preparation in medical school is responsible for the high rate of attrition seen in general surgery residency.

We performed a national prospective cohort study of all categorical general surgery interns who entered training in the 2007-2008 academic year. Interns answered questions about their medical school experience and reasons for pursuing general surgery residency. Responses were linked with American Board of Surgery residency completion data. Multivariable logistic regression was used to evaluate the association between medical school experiences and residency attrition.

Seven hundred and ninety-two surgery interns participated, and the overall attrition rate was 19.3%. Most interns had performed ≤8 wk of third year surgery clerkships (53.2% of those who completed versus 49.7% of those who dropped out, P = 0.08). After multivariable adjustment, shorter duration of third year rotations was protective from attrition (OR: 0.53, 95% CI: 0.29-0.99; P = 0.05). There was no difference in attrition based on whether a surgical subinternship was performed (OR: 0.67, 95% CI: 0.38-1.19; P = 0.18). Residents who perceived that their medical school surgical faculty were happy with their careers were less likely to experience attrition (OR: 0.57, 95% CI: 0.34-0.96; P = 0.03), but those who had gotten along well with attending surgeons had higher odds of attrition (OR: 2.93, 95% CI: 1.34-6.39, P < 0.01).

Increased quality, rather than quantity, of clerkships is associated with improved rates of residency completion. Learner relationships with positive yet demanding role models were associated with a reduced risk of attrition.
