Core Tip
Core tip: Colonoscopy quality is essential to effective colorectal cancer screening. Polypectomy rates (PRs) of 40% in men and 30% in women have recently been proposed as screening colonoscopy quality indicators. In this prospective cohort study, we sought to estimate and compare screening PRs in Québec with published screening colonoscopy quality benchmarks. We found that sex-specific screening PRs benchmarks were rarely met. The very low screening PRs in patients aged 50-54 could not be explained by shorter than recommended screening intervals. Further research is needed to understand the discrepancy between quality benchmarks and clinical practice.
