Assessment of the impact of an educational course on knowledge of appropriate EUS indications

The knowledge level of EUS among gastroenterologists likely influences the appropriateness of requested indications for EUS. It remains unknown what the impact is of a short EUS course, involving didactic teaching, on knowledge levels of EUS indications for EUS. The aim of this study was to assess the impact of a 3-day educational course on knowledge levels of attending gastroenterologists regarding the appropriateness of indications for EUS.

A questionnaire was designed that tested knowledge of indications for EUS in 4 anatomic sites: esophagus, gastroduodenum, hepatopancreatobiliary system, and colorectum. This questionnaire was distributed to all attendees of a 3-day EUS educational course. All attendees completed the survey before and immediately after the course.

A total of 24 gastroenterologists completed the pre- and post-course survey. Before the course, respondents scored highest in questions on EUS applications in the gastroduodenum (94%) and the hepatopancreatobiliary system (88%) compared with the esophagus (72%) and the colorectum (74%). Statistically significant improvements in knowledge were recorded in all organ categories: gastroduodenum (100%, p = 0.002 vs. pretest score), hepatopancreatobiliary system (99%, p < 0.0001), esophagus (92%, p < 0.0001), and colorectum (93%, p = 0.0004). The biggest improvement was observed in knowledge levels for the esophagus (20%) and the colorectum (18%).

There was a consistent improvement in the gastroenterologists' knowledge levels of EUS indications among all organ categories after an educational course. Our findings suggest that education enhances gastroenterologists' understanding of EUS. Future studies should seek to assess the impact of these improved knowledge levels on the appropriateness of EUS referral patterns.
