BACKGROUND
Although validated colonoscopy assessment tools exist, they do not measure efficiency. This study aimed to assess content validity of polypectomy efficiency (PE) and neoplastic polypectomy efficiency (NPE) as colonoscopy efficiency indices.
METHODS
Data from a randomized controlled trial evaluating polypectomy among gastroenterology trainees were utilized. PE and NPE were defined as number of polyps (or neoplastic polyps) removed/withdrawal time × 100. Content validity was assessed by determining the association between efficiency indices and polypectomy times.
RESULTS
20 trainees performed 601 colonoscopies. There was a strong association between PE/NPE and actual polypectomy times: as polypectomy time increased by 1 minute, the PE decreased by 0.48 ( = 0.001) and NPE decreased by 0.24 ( = 0.03).
CONCLUSIONS
The study proposed and provided content validity for PE and NPE as colonoscopy efficiency indices.
背景
尽管存在经过验证的结肠镜检查评估工具，但它们并不能衡量效率。本研究旨在评估息肉切除术效率（PE）和肿瘤性息肉切除术效率（NPE）作为结肠镜检查效率指标的内容效度。
方法
本研究使用了一项评估胃肠病学受训者息肉切除术的随机对照试验的数据。PE 和 NPE 定义为切除的息肉数量（或肿瘤性息肉）/退出时间×100。通过确定效率指标与息肉切除术时间之间的关联来评估内容效度。
结果
20 名受训者进行了 601 次结肠镜检查。PE/NPE 与实际息肉切除术时间之间存在很强的关联：息肉切除术时间增加 1 分钟，PE 降低 0.48（=0.001），NPE 降低 0.24（=0.03）。
结论
该研究提出并提供了作为结肠镜检查效率指标的 PE 和 NPE 的内容效度。
