Hypothesis
Is there a difference in cecal intubation rates between morning and afternoon colonoscopies?
Conclusion
Cecal intubation rates are lower in the afternoon compared to the morning, primarily due to poorer bowel preparation quality.
Supporting Evidence
- Cecal intubation rates were 95.0% in the morning group and 93.6% in the afternoon group.
- Bowel preparation quality was significantly better in the morning group.
- After adjusting for gender, age, and bowel preparation quality, no significant difference in completion rates was found.
Takeaway
Doctors found that patients do better with colonoscopies in the morning than in the afternoon because they prepare better for the test.
Methodology
Retrospective, single-center study comparing cecal intubation rates for colonoscopies performed in the morning and afternoon over approximately 12 months.
Potential Biases
Potential bias due to subjective assessment of bowel preparation quality and the practice patterns of endoscopists.
Limitations
Data was collected retrospectively, and there may be confounding factors; also, bowel preparation quality was not consistently documented.
Participant Demographics
Mean age was 63.3 years, with 59.4% male and 40.6% female participants.
