Article Title: Community Gastroenterologists Can Learn Diminutive Colon Polyp Histology Characterization with Narrow Band Imaging by a Computer Based Teaching Module
Abstract: OBJECTIVE: The aim of the study was to evaluate the impact of computer based teaching module on the performance of community gastroenterologists for characterization of diminutive polyps (/=90% or low - 90%. Following this, they reviewed the teaching module and assessed the posttest videos. Performance characteristics were calculated for pre and posttest by comparing predicted histology with actual histology. Fisher's exact test was used for analysis and kappa statistic was calculated for interobserver agreement. RESULTS: 15 gastroenterologists in community practice completed the study. Sensitivity, specificity, accuracy and negative predictive value in characterization of polyp histology improved significantly in posttest compared to pretest. In post test, accuracy was 92% for high confidence diagnoses and proportion of these increased with training from 46% (pretest) to 64% (posttest); p0.001. Interobserver agreement for diagnosis improved from fair (kappa = 0.23) in pre test to moderate (kappa = 0.56) in posttest. CONCLUSIONS: A teaching module using video clips can be used to teach community gastroenterologists polyp histology characterization by narrow band imaging. Whether this translates into real time high accuracy in polyp detection needs to be further evaluated.
