Core Tip

Core tip: Adenoma and polyp detection rates are important colonoscopy quality indicators. Competence in colonoscopy is measured by motor skills and not adenoma detection rate (ADR) and polyp detection rate (PDR). Recent guidelines recommend at least 275 colonoscopies to achieve competence. In this study, we found that ADR, PDR, adenoma per colon, and polyp per colon significantly increase throughout fellowship training. Fellows achieve the ADR and PDR of attendings after 262 and 292 colonoscopies. The variability of polyp detection among fellows suggests that ADR and PDR could be used during fellowship as part of periodic feedback.
