ABSTRACT
BACKGROUND: The American Board of Surgery In-training Examination (ABSITE) is an important marker of medical knowledge. It is unclear what factors predict or improve these scores. We evaluated demographics, United States Medical Licensing Examination (USMLE) step 1 and 2 scores, and surgical rotations during the intern year to determine if there were any correlations with the ABSITE performance. METHODS: This was a multicenter retrospective review during a 6-y period, investigating the correlation and association of demographics, USMLE scores, and types of rotations on the ABSITE percentile score of interns. Demographics included age, gender, race/ethnicity, U.S. versus international/foreign medical graduate for stratified analyses. Descriptive analysis was performed with ANOVA, correlation was evaluated with 95% confidence interval, and significance was defined as P < 0.05. RESULTS: Complete records obtained on 89 interns from six different general surgery programs over 6 y revealed that there was a significant correlation between USMLE 1 and 2 with the ABSITE. USMLE 2 correlation was the strongest (r = 0.44, 95% confidence interval = [0.25-0.60], P < 0.05). There was a significant difference in ABSITE performance (mean score difference of 17.3 percentile, P = 0.01) of interns who had an intensive care unit rotation before examination. Other surgical rotations were not associated with an ABSITE difference. Demographic factors such as age, gender, race/ethnicity, or medical graduate background status were not associated with ABSITE scores. CONCLUSIONS: USMLE step 2 scores had a higher correlation with intern ABSITE performance. An intensive care unit rotation before taking the ABSITE was associated with a significant difference in their percentile scores. Demographic factors were not correlated with ABSITE performance.
