Introduction: Quality measures for colonoscopy such as adenoma detection rate (ADR) have been proposed to be surveilled for ensuring minimum standards. However, its direct measurement is time consuming and often neglected. Extrapolating ADR and other quality measures from polyp detection rate (PDR) can be a pragmatic alternative. Objective: To determine quotients for estimating ADR and sessile serrated adenoma/polyp detection rate (SSA/P-DR) from PDR in an Australian cohort. Methods: Consecutive adult patient colonoscopies during a 1-year period were retrospectively assessed in a single Australian tertiary endoscopy center. Adenoma detection quotient (ADQ) and SSA/P detection quotient (SSA/P-DQ) were defined as the division of ADR and SSA/P-DR by PDR, respectively. The primary outcome was the number of procedures to achieve a stable cumulative ADQ and SSA/P-DQ. Secondary outcomes included evaluation of ADQ and SSA/P-DQ in different subsets. Results: In total, 2,657 colonoscopies were performed by 15 endoscopists in 2016. The ADR, SSA/P-DR, and PDR found were 32.2, 6.7, and 47.3%, respectively. The ADQ and SSA/P-DQ values found were 0.68 and 0.14, respectively. After approximately 500 procedures, both ADQ and SSA/P-DQ became stable. Interclass correlation coefficient (ICC) for the prediction of ADR from ADQ was excellent for all endoscopists that performed #x3e;177 procedures in that year (ICC 0.84). Conclusions: ADQ and SSA/P-DQ values were consistent when over 500 procedures were analyzed. ADQ had an excellent correlation with ADR when #x3e;177 procedures per endoscopist were evaluated.

息肉检测率作为腺瘤和无蒂锯齿状腺瘤/息肉检测率的替代指标。

简介：已提议对结肠镜检查的质量措施（如腺瘤检出率 (ADR)）进行监测，以确保最低标准。然而，它的直接测量是耗时的并且经常被忽视。从息肉检出率 (PDR) 推断 ADR 和其他质量指标可能是一种实用的替代方法。目的：确定在澳大利亚队列中从 PDR 估计 ADR 和无蒂锯齿状腺瘤/息肉检出率 (SSA/P-DR) 的商。方法：在澳大利亚一家三级内窥镜检查中心对 1 年内连续进行的成年患者结肠镜检查进行了回顾性评估。腺瘤检出商 (ADQ) 和 SSA/P 检出商 (SSA/P-DQ) 分别定义为 ADR 和 SSA/P-DR 除以 PDR。主要结果是达到稳定累积 ADQ 和 SSA/P-DQ 的程序数量。次要结果包括对不同亚组的 ADQ 和 SSA/P-DQ 的评估。结果：2016 年，15 名内镜医师共进行了 2,657 次结肠镜检查。发现的 ADR、SSA/P-DR 和 PDR 分别为 32.2%、6.7% 和 47.3%。发现的 ADQ 和 SSA/P-DQ 值分别为 0.68 和 0.14。经过大约 500 次手术后，ADQ 和 SSA/P-DQ 都变得稳定。从 ADQ 预测 ADR 的组间相关系数 (ICC) 对于当年执行 #x3e;177 程序的所有内镜医师来说都非常出色 (ICC 0.84)。结论：当分析超过 500 个程序时，ADQ 和 SSA/P-DQ 值是一致的。当评估每位内镜医师#x3e;177 次手术时，ADQ 与 ADR 具有极好的相关性。
