Adjusted colonoscopy completion rates offer a more accurate measure of technical skill by minimizing disease-related incompletions. This standardization aids colonoscopists in evaluating their experience and improves reporting consistency.

Area of Science:

  • Gastroenterology
  • Medical Procedures
  • Quality Improvement

Background:

  • Colonoscopy completion rate is a key indicator of technical proficiency.
  • Current reporting lacks uniformity, hindering accurate comparisons.
  • Few studies isolate colonoscopy completion as a sole metric.

Purpose of the Study:

  • Establish consistent criteria for reporting colonoscopy completion rates.
  • Enable colonoscopists to better evaluate their individual performance.
  • Promote uniformity in assessing colonoscopy success.

Main Methods:

  • Prospective study of 2907 patients to assess colonoscopy completion rate.
  • Defined completion as the colonoscope reaching the colon's end.
  • Reported crude rates (all cases) and adjusted rates (excluding stool/disease).

Related Experiment Videos

Main Results:

  • Crude completion rate was 93.6%; adjusted rate was 98.8%.
  • Incompletions were due to stool (47), disease (97), and pain/tortuosity (34).
  • Adjusted rates minimized demographic and disease-related differences, except for sex and hysterectomy status.

Conclusions:

  • Crude completion rates are influenced by various factors, complicating comparisons.
  • Adjusted rates better reflect technical ability by accounting for disease.
  • Standardized reporting of adjusted completion rates can improve colonoscopy evaluation.
