UNASSIGNED: Background and aims: Optimal teaching methods for disease recognition using probe-based confocal laser endomicroscopy (pCLE) have not been developed. Our aim was to compare in-class didactic teaching vs. self-directed teaching of Barrett's @entity5 diagnosis using pCLE. Methods: This randomized controlled trial was conducted at a tertiary @entity4207 center. Study @entity1 with no prior pCLE experience were randomized to in-class didactic (group 1) or self-directed teaching groups (group 2). For group 1, an expert conducted a classroom teaching session using standardized educational material. @entity1 in group 2 were provided with the same material on an audio PowerPoint. After initial training, all @entity1 graded an initial set of 20 pCLE videos and reviewed correct responses with the expert (group 1) or on audio PowerPoint (group 2). Finally, all @entity1 completed interpretations of a further 40 videos. Results: Eighteen trainees (8 medical students, 10 gastroenterology trainees) participated in the study. Overall diagnostic accuracy for @entity5 prediction by pCLE was 77% (95% confidence interval [CI] 74.0%-79.2%); of predictions made with high confidence (53%), the accuracy was 85% (95%CI 81.8%-87.8%). The overall accuracy and interobserver agreement was significantly higher in group 1 than in group 2 for all predictions (80.4% vs. 73%; P=0.005) and for high confidence predictions (90% vs. 80%; P<0.001). Following feedback (after the initial 20 videos), the overall accuracy improved from 73% to 79% (P=0.04), mainly driven by a significant improvement in group 1 (74% to 84%; P<0.01). Accuracy of prediction significantly improved with time in endoscopy training (72% students, 77% FY1, 82% FY2, and 85% FY3; P=0.003). Conclusion: For novice trainees, in-class didactic teaching enables significantly better recognition of the pCLE features of @entity355 than self-directed teaching. The in-class didactic group had a shorter learning curve and were able to achieve 90% accuracy for their high confidence predictions.
