Case-mix-adjusted mean number of polyps per 100 procedures: a new candidate gold standard colonoscopy key performance indicator

We demonstrate a method to compute a novel case-mix-adjusted KPI, aMNP, which is significantly associated with PDR, PPR, PCCRC and JAG GRS. Histological data were unavailable. aMNP addresses many limitations of ADR, adjusts for warranted variation in detection, and hence may improve audit and feedback engagement. We propose it as a candidate gold standard KPI for reporting endoscopy quality.
