Analysis of Factors Influencing the Quality of Bowel Preparation Before Colonoscopy in IBD Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

Standard Pre-colonoscopy Bowel Preparation Protocol: This involves standard clinical instructions including a low-residue diet prior to colonoscopy and the administration of bowel cleansing agents (e.g., Polyethylene Glycol) according to the split-dose regimen as per each participating center's routine practice. The timing, dosage, and specific agent used follow existing institutional guidelines.

Study summary

The primary objectives of this project are twofold. On the one hand, it aims to investigate the current status of bowel preparation protocols and their quality in IBD patients undergoing colonoscopy, particularly focusing on the implementation of these protocols across hospitals following the release of the 2023 bowel preparation guidelines. This will further standardize and optimize bowel preparation practices in China. On the other hand, the project seeks to identify and examine various risk factors contributing to poor bowel preparation quality in IBD patients, analyze their correlation with bowel preparation scores, and develop a risk prediction model for failed bowel preparation. This will provide a theoretical foundation for formulating personalized bowel preparation regimens tailored to individual patient conditions in the future.

Eligibility

Primary outcome measure(s)

• adequate bowel preparation rate — The adequate bowel preparation rate can be assessed immediately upon completion of colonoscopy
  Proportion of subjects with Boston Bowel Preparation Scale (BBPS) scores ≥ 2 in all bowel segments.
