A high-quality colonoscopy requires a thorough mucosal inspection to identify neoplastic polyps. Adenoma detection rate (ADR) and withdrawal time (WT) may be difficult to measure, are subject to ‘gaming,’ and do not provide actionable feedback for improvement. A standardized scale to assess colonoscopy inspection quality (CIQ) provides targeted feedback, but is time-consuming for raters. The aim of this study is to determine whether colonoscopy-naive (“novice”) rater assessments of CIQ correlate with expert rater assessments, and with standard metrics of colonoscopy quality.
