What this Trial Is About
Researchers are studying the quality of bowel preparation in patients with Inflammatory Bowel Disease (IBD) who are undergoing colonoscopy. This project aims to assess how well current bowel preparation protocols are followed across hospitals in China after new 2023 guidelines were introduced. It also seeks to identify risk factors linked to poor bowel preparation and develop a model to predict failed preparation, helping to personalize future bowel prep plans. Participants will follow standard bowel preparation protocols including a low-residue diet and use of bowel cleansing agents like Polyethylene Glycol, following each hospital's routine practice. The study is observational and involves patients aged 18 to 75 years diagnosed with IBD and scheduled for colonoscopy. After colonoscopy, patients complete a questionnaire about factors affecting their bowel preparation quality and details of their prep routine. During the study, researchers will record bowel preparation quality using the Boston Bowel Preparation Scale and collect colonoscopy results and disease activity scores. They will also measure the rate of adequate bowel preparation immediately after the procedure and assess patient satisfaction. Participants are involved in answering questionnaires and undergoing routine colonoscopy as part of their clinical care. The study follows participants from preparation through colonoscopy, with a focus on improving bowel prep standards and outcomes.
