Optimized Sedation Improves Colonoscopy Quality Long-Term

الملخص EN

Background.

Quality monitoring and improvement is prerequisite for efficient colonoscopy.

Aim.

To assess the effects of increased sedation administration on colonoscopy performance.

Materials and Methods.

During Era 1 we prospectively measured four colonoscopy quality indicators: sedation administration, colonoscopy completion rate, adenoma detection rate, and early complications rate in three cohorts: cohort A: intention for total colonoscopy cases; cohort B: cohort A excluding bowel obstruction cases; cohort C: CRC screening-surveillance cases within cohort B.

We identified deficiencies and implemented our plan to optimize sedation.

We prospectively evaluated its effects in both short- (Era 2) and long-term period (Era 3).

Results.

We identified that sedation administration and colonoscopy completion rates were below recommended standards.

After sedation optimization its use rate increased significantly (38.1% to 55.8% to 69.5%) and colonoscopy completion rate increased from 88.3% to 90.6% to 96.4% in cohort B and from 93.2% to 95.3% to 98.3% in cohort C, in Eras 1, 2, and 3, respectively.

Adenoma detection rate increased in cohort C (25.9% to 30.6% to 35%) and early complications rate decreased from 3.4% to 1.9% to 0.3%.

Most endoscopists increased significantly their completion rate and this was preserved long-term.

Conclusion.

Increased sedation administration results in long-lasting improvement of colonoscopy quality indicators.
