Previous studies have shown that adenoma detection — considered to be the prime measure of quality of mucosal inspection during colonoscopy — is highly variable among endoscopists and is partly explained by withdrawal time (JW Gastroenterol Aug 14 2009).
To determine whether specific interventions would be successful in improving adenoma detection rates, investigators evaluated the performance of 43 endoscopists in a community setting who were exposed to five quality-improvement interventions during a 3-year period in which they performed 47,253 screening colonoscopies in average-risk persons aged 50 and older. The interventions were implemented in the following sequence:
Blinded review of individual adenoma detection rates
Unblinded review of…
