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.
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.
This was a prospective educational evaluation study.
Academic endoscopy unit.
This study involved 28 trainees of varying CE experience (medical students, gastroenterology trainees) and 4 CE experts.
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.
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).
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%).
Computer-based learning has a potentially significant role in the development of a training syllabus for CE and in CE accreditation.
胶囊内镜检查（CE）使用的迅速扩展引发了关于培训需求和培训提供的讨论。CE所需的病变识别技能非常适合基于计算机的培训。
本研究的目的是前瞻性评估基于计算机的CE培训和测试模块对不同经验学员的教育效果。
这是一项前瞻性教育评估研究。
学术性内镜科室。
本研究纳入了28名具有不同CE经验的学员（医学生、胃肠病学实习生）和4名CE专家。
没有CE经验的学员（医学生和胃肠病学实习生）完成一个由60道题组成的基于计算机的测试模块，该模块包含30秒的视频片段和多项选择题。在没有反馈的情况下，学员随后完成一个全面的、菜单驱动的基于计算机的CE培训模块。然后再次完成测试模块并给予反馈。4名CE专家对测试模块的专家表现设定了基准。
第一个指标是学员和专家在测试模块上的基线表现差异（以确定结构效度）。第二个指标是培训后测试模块上的表现变化（以确定培训模块的内容效度）。
CE专家（平均73.8%±8.0%）、胃肠病学实习生（49.5%±10.9%）和医学生（29.5%±3.3%）在基线表现上存在显著差异（P<.001）。两组学员在培训后表现均显著提高（P<.001）（胃肠病学实习生培训后得分62.1%±7.7%；医学生46.7%±6.8%）。
基于计算机的学习在CE培训大纲的制定和CE认证中可能具有重要作用。
