Can trauma leagues contribute to better cognitive performance and technical skills of medical students? The experience of the Unicamp trauma league

Purpose Trauma leagues (TLs) are extracurricular programs that offer medical students supervised exposure to trauma and acute care surgery, mentorship, and participation in other academic activities. TLs are fully approved medical schools, and currently, over 100 TLs exist in Brazil. We hypothesized that the performance/competence of medical students who participated in TLs was superior compared to non-participants. This study evaluated and compared the cognitive performance and technical skills of the two groups. Methods This retrospective cohort study evaluated the performance of TL medical students to non-TL alumni from 2005 to 2017, using the students’ academic performance coefficient, Clinical Competence Assessment, and Progress Test results. SigmaPlot 12.0 software was used to perform statistical analyses, including Mann–Whitney comparison tests and the Kruskal–Wallis test to confirm the data. Results Of the 1366 medical students who graduated from a Brazilian university, 966 were included, with 17.9% having participated in TL. Compared to non-TL participants, TL students demonstrated better cognitive performance according to the performance coefficient (p = 0.017) and Progress Test result (p
