Assessment of endoscopist competence is an increasingly important component of colonoscopy quality assurance. In this study from the Joint Advisory Group on Gastrointestinal Endoscopy, validity evidence is provided for the use of the Direct Observation of Procedural Skills assessment tool in the formative setting during training. In this national UK dataset, overall colonoscopy competence was typically achieved after 200-249 procedures, although certain complex procedural skills ("proactive problem solving" and "loop management") had not reached the threshold for competence even after 300 procedures. These data will help inform the development and/or refinement of certification policies and practices in jurisdictions around the world.

使用评估数据来表征结肠镜检查能力的发展。

内镜医师能力的评估是结肠镜检查质量保证中越来越重要的组成部分。在胃肠道内窥镜检查联合咨询小组的这项研究中，为训练过程中的形成性环境中使用过程技能直接观察评估工具提供了有效性证据。在这个英国国家数据集中，尽管经过300次手术后，某些复杂的程序技能（“主动解决问题”和“回路管理”）仍未达到能力门槛，但通常在200-249次手术后即可达到总体结肠镜检查能力。这些数据将有助于为全球各地的认证政策和实践的发展和/或完善提供信息。
