Objective
To establish a standardized training program for endoscopic pathogen visualization literacy (EPVL) based on fluorescence rapid on-site evaluation (ROSE) technology for gastroenterologists, and to evaluate its training efficacy.
Methods
A prospective quasi-experimental study was conducted. A total of 54 gastroenterology trainees were non-randomly allocated into the EPVL training group (Group A, n=28, 16-hour comprehensive training) and the control group (Group B, n=26, 3.5-hour traditional teaching). Pre- and post-training assessments included theoretical examinations, fluorescence ROSE image interpretation tests (30 parallel images per set), interpretation speed measurement, and clinical decision-making integration evaluation. The primary outcome was the change in image interpretation accuracy, analyzed by ANCOVA with pre-test scores as the covariate.
Results
Baseline characteristics were comparable between groups (P>0.05 for all demographic variables and pre-test scores). Group A showed significant improvement in image interpretation accuracy from 57.8±13.6% pre-training to 82.5±11.2% post-training (improvement of 24.7%, paired t=-12.86, P<0.001), while Group B improved from 58.5±13.0% to 71.0±13.5% (improvement of 12.5%, paired t=-5.24, P<0.001). After ANCOVA adjustment for pre-test scores, the between-group difference was significant (F(1, 51)=10.95, P=0.0017, η 2 =0.177), with Cohen’s d=0.94 (large effect size). Interpretation speed in Group A (19.2±2.8 s/image) was significantly faster than in Group B (32.5±6.0 s/image, t=-10.45, P<0.001). Clinical decision-making scores were significantly higher in Group A (80.5±8.0 vs. 65.3±11.5, t=5.60, P<0.001). The Kappa agreement with the gold standard in Group A improved from 0.56±0.18 to 0.84±0.11 (t=-8.35, P<0.001). Participant satisfaction exceeded 88%.
Conclusion
The EPVL training program significantly improves gastroenterologists’ fluorescence ROSE image interpretation accuracy, speed, and clinical decision-making integration, providing a novel and effective standardized training paradigm for digestive endoscopy education.
