Summary Background Colonoscopy is an operator‐dependent procedure. The medical literature describes disparity in colonoscopy performance with respect to polyp detection, caecal intubation rates and procedural times. Aim To assess prospectively the impact of feedback among a large cohort of colonoscopists on three performance parameters: caecal intubation rate, insertion time and withdrawal time. Method In a prospective clinical study, procedural data from all out‐patient colonoscopies performed by attending gastroenterologists at our institution were recorded routinely in a computerized database. Enhanced serial feedback was provided on a quarterly basis for three procedure parameters: intubation to caecum, insertion time and withdrawal time. Feedback (absolute value, % rank and group distribution) was sent by email every 3 months beginning with January 2005 feedback for all of 2004, and subsequently quarterly in April 2005 (for January–March 2005), July 2005 (for April–June 2005) and October 2005 (for July–September 2005). Results Feedback was provided to 58 endoscopists with a median experience level of 8 years. There was a relative decline of 19% in incomplete procedures, with median caecal non‐intubation rates decreasing from 4.7% to 3.8% following the introduction of feedback while median insertion times declined from 10.6 to 9.5 mins, P = 0.02. Median withdrawal times did not change significantly, 9.1–8.9 mins, P = 0.6. Conclusions Feedback by email appears to improve colonoscopy performance, enhancing completion rates and shortening insertion times without compromising withdrawal times.
