Summary
Afternoon colonoscopies do not decrease adenoma detection rate (ADR). Performing colonoscopies in full-day blocks or 30-minute slots does not compromise ADR, even late in the day.
Area of Science:
- Gastroenterology
- Endoscopy
- Colorectal Cancer Screening
Background:
- Endoscopist fatigue may reduce adenoma detection rate (ADR).
- The impact of scheduling on afternoon ADR requires further investigation.
Purpose of the Study:
- To evaluate afternoon ADR in half-day versus full-day colonoscopy blocks.
- To determine if procedure time or complexity influences afternoon ADR.
Main Methods:
- Retrospective chart review of consecutive colonoscopies in patients over 45.
- Analysis of adenoma detection rate (ADR) based on procedure timing and scheduling.
Main Results:
- No significant difference in ADR was found between full-day and half-day blocks (35% vs 32%).
- Afternoon ADR was not affected by increasing queue position or procedure time.
- Overall afternoon ADR (33%) was comparable to morning ADR (30%).
Conclusions:
- Colonoscopies can be performed in full-day blocks without compromising ADR.
- Scheduling colonoscopies in 30-minute slots does not negatively impact ADR.
- Endoscopist fatigue does not appear to significantly affect ADR in this study.
