title: Evaluation of formal feedback on endoscopic competence among trainees: the EFFECT trial.
abstract: BACKGROUND
  The medical literature describes disparity in colonoscopy performance. This randomised, controlled study aimed to characterise the impact of feedback on colonoscopy performance among gastroenterology (GI) trainees.
  
  
  METHODS
  Gastroenterology trainees of similar experience levels who independently performed 581 colonoscopies over the study period were randomised to receive feedback/no feedback on their colonoscopy performance.
  
  
  RESULTS
  Baseline colonoscopy performance was similar in both groups. Following feedback, caecal intubation improved by 10.5% (from 72.9 to 83.4%, p = 0.04) in the feedback group and declined by 6.1% (from 78 to 71.9%, p = 0.2) in the control group; polyp detection improved by 5.1% (from 12.9 to 18.0%, p = 0.2) in the feedback group and by 2.9% (from 16.7 to 19.6%, p = 0.5) in the control group.
  
  
  CONCLUSIONS
  Systematic feedback appears to enhance colonoscopy performance among GI trainees.
