What are the priority quality indicators for colonoscopy in real‐world clinical practice?

Abstract

Colonoscopy is widely used as a colorectal cancer (CRC) screening tool. The effectiveness of a screening colonoscopy is associated with a decreased risk of CRC. However, colonoscopy is an operator‐dependent procedure, and endoscopists' quality performance varies widely. This article reviewed the priority metrics and practices that contribute to high‐quality screening colonoscopy in real‐world clinical practice. With growing evidence, quality indicators have been subject to intense research and associated with reducing postcolonoscopy CRC incidence and mortality. Some quality metrics can reflect an endoscopy unit‐based practice (i.e. quality of bowel preparation and withdrawal time). Other quality indicators primarily reflect individuals' skill and knowledge (i.e. cecal intubation rate, adenoma detection rate, and appropriately assigned follow‐up colonoscopy interval). Measurement and improvement of priority quality indicators for colonoscopy should be made at both the endoscopist and unit levels. Substantial evidence supports the impact of high‐quality colonoscopy in reducing the incidence of postcolonoscopy CRC.
