Obtaining a categorical general surgery residency position is recognized as a highly challenging process, and many aspiring surgeons find themselves matching into a preliminary position. The American Board of Surgery In-Training Examination (ABSITE) is relevant as a discriminator, as it is the only national evaluation metric that compares residents between programs. This study examines the correlation between ABSITE performance and the likelihood of obtaining a categorical position for non-designated preliminary surgery residents. Retrospective analysis of preliminary residents who completed the ABSITE between 2011 and 2021 at a single academic training program. 108 preliminary residents were included. Among preliminary residents who were successful in securing a categorical position, the average ABSITE percentile was 59 (SD = 26.7). In contrast, those who were not able to secure a categorical position, the average ABSITE percentile was 23.6 (SD = 25.3). There was a strong significant correlation between ABSITE percentile and securing a categorical position (P < 0.001). There was a significant association between citizenship and gaining a categorical position, with US citizens being significantly more likely to successfully gain a categorical position (P = 0.01; OR 3.32 (95% CI 1.28-8.56)). There was not a significant correlation between citizenship and ABSITE score. This study presents compelling evidence that ABSITE percentile score is positively associated with the probability of securing a categorical position for preliminary general surgery residents. It is therefore imperative that both preliminary residents and their programs place a high value on ABSITE performance to enhance successful career progression.
