Practice Makes Perfect: Introducing a Question Bank for ABSITE Preparation Improves Program Performance

The American Board of Surgery In-Training Examination (ABSITE) is an important predictor of passing the Qualifying Examination and a determinant of fellowship competitiveness.

Study the impact of providing program-wide access to a commercially available question bank for ABSITE preparation.

The surgery residency program purchased access to the TrueLearn question bank in 2018 A paired sample t test analysis compared the 2018 ABSITE percentage and percentile scores, prior to practice question bank access to 2019 ABSITE percentile scores. A simple linear regression analysis was calculated to predict improvement in percentage scores from 2018 to 2019 based on total number of practice questions as well as number of correct practice questions completed. Data were analyzed using SPSS.

Among the residents utilizing practice questions with serial exam scores, the individual resident ABSITE percentage of correct questions showed a statistically significant improvement after introduction of the question bank from 2018 (mean = 68.7, standard deviation = 7.3) to 2019 (mean = 72.2, standard deviation = 7.2; t(35) = -4.529, p < 0.001). A statistically significant regression equation both linear (F(1,33) = 6.274, p = 0.017) and logarithmic (F(1,33) = 7.405, p =0.01) was found with an R2 of 0.160 and 0.183, respectively, for total number of practice questions completed, signifying that more completed practice questions correlated with a higher improvement in ABSITE percentage score. The improvement in residents' ABSITE percentage score increased by 3 ± 1 percentage point for each 100 practice questions completed from 2018 to 2019 (Figure 1). A significant regression equation was also found for improvement in percentage score among all residents (F (1,33) = 8.211, p = 0.007) with an R2 of 0.199 for the number of correct practice questions completed.

Use of a commercial question bank improved overall ABSITE scores. More questions answered translated into improved performance. Percent correct on the practice questions also correlated strongly with performance. Programs seeking to improve scores may wish to provide access to a question bank.
