Background:
Knowledge of quality measures in endoscopy among trainees is unknown.
Objective:
To assess knowledge of endoscopy-related quality indicators among U.S. trainees and determine whether it improves with a Web-based intervention.
Design:
Randomized, controlled study.
Setting:
Multicenter.
Participants:
This study involved trainees identified from the American Society for Gastrointestinal Endoscopy membership database.
Intervention:
Participants were invited to complete an 18-question online test. Respondents were randomized to receive a Web-based tutorial (intervention) or not. The test was readministered 6 weeks after randomization to determine the intervention's impact.
Main Outcome Measurements:
Baseline knowledge of endoscopy-related quality indicators and impact of the tutorial.
Results:
A total of 347 of 1220 trainees (28%) completed the test; the mean percentage of correct responses was 55%. For screening colonoscopy, 44% knew the adenoma detection rate benchmark, 42% identified the cecal intubation rate goal, and 74% knew the recommended minimum withdrawal time. A total of 208 of 347 trainees (59%) completed the second test; baseline scores were similar for the tutorial (n = 106) and no tutorial (n = 102) groups (56.4% vs 56.9%, respectively). Scores improved after intervention for the tutorial group (65%, P = .003) but remained unchanged in the no tutorial group. On multivariate analysis, each additional year in training (odds ratio [OR] 2.3; 95% confidence interval [CI], 1.5-3.4), training at an academic institution (OR 2.6; 95% CI, 1.1-6.3), and receiving the tutorial (OR 3.2; 95% CI, 1.7-5.9) were associated with scores in the upper tertile.
Limitations:
Low response rate.
Conclusion:
Knowledge of endoscopy-related quality performance measures is low among trainees but can improve with a Web-based tutorial. Gastroenterology training programs may need to incorporate a formal didactic curriculum to supplement practice-based learning of quality standards in endoscopy.
