Abstract

BACKGROUND:

The rapid expansion in use of capsule endoscopy (CE) has led to discussion about training needs and provision. The lesion recognition skills required for CE are ideally suited to computer-based training.

OBJECTIVE:

The aim of this study was to prospectively evaluate the educational effectiveness of a computer-based CE training and testing module on trainees with varying experience.

DESIGN:

This was a prospective educational evaluation study.

SETTING:

Academic endoscopy unit.

PATIENTS:

This study involved 28 trainees of varying CE experience (medical students, gastroenterology trainees) and 4 CE experts.

INTERVENTION:

Trainees (medical students and gastroenterology trainees) without CE experience completed a 60-question, computer-based test module consisting of 30-second video clips and multiple-choice questions. Without feedback, trainees then completed a comprehensive, menu-driven, computer-based CE training module. The test module was then completed a second time and feedback was given. Expert performance on the test module was benchmarked by 4 CE experts.

MAIN OUTCOME MEASUREMENTS:

The first measure was the difference in baseline performance on the test module between trainees and experts (to determine construct validity). The second measure was a change in performance on the test module after training (to determine content validity of the training module).

RESULTS:

A significant difference was noted in baseline performance (P < .001) among CE experts (mean 73.8% +/- 8.0%), gastroenterology trainees (49.5% +/- 10.9%), and medical students (29.5% +/- 3.3%). Performance improved significantly (P < .001) in both trainee groups after training (gastroenterology trainees' posttraining score 62.1% +/- 7.7%; medical students' 46.7% +/- 6.8%).

CONCLUSION:

Computer-based learning has a potentially significant role in the development of a training syllabus for CE and in CE accreditation.
