About this trial
The primary objectives of this study are twofold:
Firstly, to investigate the current status of bowel preparation protocols and their quality across hospitals at various levels in China, particularly following the release of the updated 2023 bowel preparation guidelines. This aims to standardize and optimize bowel preparation protocols nationwide.
Secondly, to identify and analyze risk factors contributing to suboptimal bowel preparation quality in patients undergoing colonoscopy. The study will examine the correlation between these factors and bowel preparation scores, establish a risk prediction model for preparation failure, and provide a theoretical foundation for developing personalized bowel preparation regimens tailored to individual patient characteristics.
