IntroductionAs interest in medicine grows, admissions committees must review an increasingly competitive pool of medical school and residency candidates. Nearly all admissions committees have moved towards a holistic review, which considers an applicant's experiences and attributes in addition to academic metrics. As such, identifying nonacademic predictors of success in medicine is necessary. Parallels between skills necessary to succeed in athletics and in medicine have been drawn, including teamwork, discipline and resiliency. This systematic review synthesises the current literature to evaluate the relationship between participation in athletics and performance in medicine.MethodsThe authors searched five databases to conduct a systematic review following PRISMA guidelines. Included studies assessed medical students, residents or attending physicians in the United States or Canada and used prior athletic participation as a predictor or explanatory variable. The review examined associations between prior athletic participation and outcomes in medical school, residency and/or as an attending physician.ResultsEighteen studies evaluating medical students (78%), residents (28%) or attending physicians (6%) met inclusion criteria for this systematic review. Twelve (67%) studies specifically assessed participants based on skill level, and five (28%) studies specifically assessed participants based on type of athletic participation (team versus individual). Sixteen studies (89%) found that former athletes performed significantly better than their counterparts (p < 0.05). These studies found significant associations between prior athletic participation and better outcomes in multiple performance indicators, including exam scores, faculty ratings, surgical errors and burnout.ConclusionsCurrent literature, although limited, suggests that prior participation in athletics may be a predictor of success in medical school and residency. This was demonstrated through objective scoring methods, such as USMLE, and subjective outcomes, such as faculty ratings and burnout. Specifically, multiple studies indicate that former athletes demonstrated increased surgical skill proficiency and decreased burnout as medical students and residents.
