@article { , title = {An interactive web-based educational tool improves detection and delineation of Barrett’s esophagus related neoplasia}, abstract = {Background \& Aims: Endoscopic detection of early Barrett’s esophagus-related neoplasia (BORN) is a challenge. We aimed to develop a web-based teaching tool for improving detection and delineation of BORN. Methods: We made high-definition digital videos during endoscopies of patients with BORN and non-dysplastic Barrett’s esophagus (NDBE). Three experts superimposed their delineations of BORN lesions on the videos using special tools. In phase 1, 68 general endoscopists from 4 countries assessed 4 batches of 20 videos. After each batch, mandatory feedback compared assessors interpretations with those from experts . These data informed selection of 25 videos for the phase 2 module, which was completed by 121 new assessors from 5 countries. A 5-video test batch was completed before and after scoring of the four 5-video training batches. Mandatory feedback was as in phase 1. Outcome measures were scores for detection, delineation, agreement delineation, and relative delineation of BORN. Results: A linear mixed-effect model showed significant sequential improvement for all 4 outcomes over successive training batches in both phases. In phase 2, median detection rates of BORN in the test batch increased by 30\% (P [less than].001) after training. From baseline to the end of the study, there were relative increases in scores of 46\% for detection, 129\% for delineation, 105\% for agreement delineation, and 106\% for relative delineation (all P [less than].001). Scores improved independent of assessors’ country of origin or level of endoscopic experience.}, doi = {10.1053/j.gastro.2018.12.021}, eissn = {1528-0012}, issue = {5}, journal = {Gastroenterology}, note = {Article not yet published in issue.
