The ability of a colonoscopist to detect colon polyps is commonly measured by the adenoma detection rate (ADR). The outcome of colonoscopy varies based on ADR, and the relationship between decreasing provider ADR and the increased risk of subsequent fatal colorectal cancer has been clearly established.1 Despite the importance of provider ADR, it is of limited value at lower provider volumes due to imprecise measurements. We have previously shown that ratings of colonoscopy inspection quality (CIQ) from video-taped colonoscopies by experts highly correlate with provider ADR, and can provide colonoscopists with specific techniques in need of remediation.2 It is unclear, however, whether these video-based evaluations are a feasible method of assessing colonoscopy quality due to a reliance upon expert evaluations. The primary aim of this study was to determine whether video-based assessments of colonoscopy inspection quality by colonoscopy-naïve raters (novice raters) correlate with assessments by expert raters and with established colonoscopy quality metrics.
