Opinion Statement:
Colonoscopy is a powerful screening method for colorectal cancer. However, colonoscopy performance is highly variable and quality indicators are needed to ensure delivery of high-quality healthcare. A multi-society task force has recently identified three priority quality indicators in colonoscopy: adenoma detection rate, cecal intubation rate, and adherence to surveillance guidelines. The best-studied quality indicator is the adenoma detection rate, which is inversely correlated to the risk of interval colorectal cancer. Other important quality determinants include colonoscopy withdrawal time and the bowel preparation quality. It is important to note that these quality metrics are interrelated and optimization at every level is necessary for any high-quality colorectal cancer screening and prevention program.
