Article Title: Randomized controlled trial of self-directed versus in-classroom teaching of narrow-band imaging for diagnosis of Barrett's esophagus-associated neoplasia
Abstract: BACKGROUND AND AIMS: Previous studies have shown that narrow-band imaging (NBI) can be taught to inexperienced gastroenterologists. However, it is unknown whether in-person training is more effective than self-directed training. The objective of this study was to compare the accuracy of diagnosing Barrett's esophagus (BE)-associated neoplasia by trainees with no prior NBI experience between in-classroom and self-directed didactic training programs. METHODS: This was a randomized controlled trial that took place at 2 tertiary-care medical centers, involving 33 participants-12 second-year medical students, 8 first-year gastroenterology fellows, 7 second-year gastroenterology fellows, and 6 third-year gastroenterology fellows. A teaching module was developed for all participants to review. Half of the participants were taught in a classroom setting by an endoscopist with expertise in NBI, whereas the other participants were in a self-directed group that received an automated version of the presentation with audio commentary. Participants completed a test of 40 randomized NBI images, predicting the histology and indicating their confidence levels in the diagnosis. RESULTS: There was no difference in accuracy between the in-classroom and self-directed groups (57.5% vs 57.2%; P = 1.0). The in-classroom group had a significantly higher percentage of high-confidence answers (57.2% vs 41.1%; P
