结肠镜筛查可以大大降低结直肠癌的发病率和死亡率。当结肠镜检查以高质量进行并附有符合临床指南的后续建议时，可以获得最大的益处。本研究旨在确定 2016 年至 2019 年（COVID-19 大流行之前的最近几年）内窥镜医生在多大程度上达到了结肠镜检查质量目标。我们检查了结肠镜检查质量的衡量标准以及胃肠道质量改进联盟建议的随访间隔，一个大型的全国性内窥镜检查登记处。该分析包括超过 250 万名 50-75 岁平均风险成年人的门诊结肠镜筛查。至少 90% 的内窥镜医师达到了充分肠道准备、盲肠插管率和腺瘤检出率的绩效目标。然而，不遵守随访间隔指南的情况很常见。对于没有结肠镜检查结果的患者，12.0％的患者接受了≤5年的随访间隔建议，而不是指南建议的10年。对于患有1-2个小管状腺瘤的患者，13.5%的患者接受了≤3年的随访间隔建议，而不是指南建议的5-10年。对于小无蒂锯齿状息肉患者，30.7%的患者接受了≤3年的随访间隔建议，而不是指南建议的5年。一些具有较高风险发现的患者接受了≥5年的随访间隔建议，而不是指南建议的3年，其中包括18.2%的晚期锯齿状病变患者。可能需要额外注意，以更一致地遵守结肠镜检查指南后续建议。版权所有 © 2024 美国胃肠内窥镜协会。由爱思唯尔公司出版。保留所有权利。

Colonoscopy screening can substantially reduce colorectal cancer incidence and mortality. Colonoscopies may achieve maximum benefit when they are performed with high quality and accompanied by follow-up recommendations that adhere to clinical guidelines. This study aimed to determine to what extent endoscopists met targets for colonoscopy quality from 2016 through 2019 (the most recent years prior to the COVID-19 pandemic).We examined measures of colonoscopy quality and recommended follow-up intervals in the GI Quality Improvement Consortium, a large nationwide endoscopy registry. The analysis included over 2.5 million outpatient screening colonoscopies in average risk adults aged 50-75 years.At least 90% of endoscopists met performance targets for adequate bowel preparation, cecal intubation rate, and adenoma detection rate. However, nonadherence to guidelines for follow-up intervals was common. For patients with no colonoscopy findings, 12.0% received a follow-up interval recommendation of ≤5 years instead of the guideline-recommended 10 years. For patients with 1-2 small tubular adenomas, 13.5% received a follow-up interval recommendation of ≤3 years instead of the guideline-recommended 5-10 years. For patients with small sessile serrated polyps, 30.7% received a follow-up interval recommendation of ≤3 years instead of the guideline-recommended 5 years. Some patients with higher risk findings received a follow-up interval recommendation of ≥5 years instead of the guideline-recommended 3 years, including 18.2% of patients with advanced serrated lesions.Additional attention may be needed to achieve more consistent adherence to guidelines for colonoscopy follow-up recommendations.Copyright © 2024 American Society for Gastrointestinal Endoscopy.
