Abstract
The inter-observer reliability of the Boston Bowel Preparation Scale (BBPS) scores was 0.987.
- The BBPS demonstrated high inter-observer reliability, indicating consistent scoring among different observers.
- Intra-observer reliability was assessed with a weighted Kappa value of 0.671, suggesting moderate agreement over time.
- The mean BBPS score for 1012 screening colonoscopies was 6.9 ± 1.8.
- BBPS scores of 5 or higher were linked to a higher polyp-detection rate of 35%, compared to 18% for scores below 5.
- The BBPS remains a valid and reliable measure of bowel preparation quality for Chinese physicians trained through video.
