A Multi-Center Randomized Controlled Trial on the Impact of Disease Subtype-Based Active Video Education on Bowel Preparation Quality in Patients With Inflammatory Bowel Disease

This multi-center, prospective, randomized controlled trial evaluates whether disease subtype-based active video education improves bowel preparation quality in patients with inflammatory bowel disease (IBD) undergoing colonoscopy. A total of 600 IBD patients from 13 centers will be randomized 1:1 to standard education plus subtype-specific video education (intervention group) or standard education alone (control group). The primary outcome is the Boston Bowel Preparation Scale (BBPS) score.
