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

Summary

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.

BEHAVIORAL

Disease Subtype-Based Active Video Education

A structured, subtype-specific educational video program tailored for patients with inflammatory bowel disease (IBD). The videos are customized based on IBD subtype (ulcerative colitis/Crohn's disease), disease activity (active/remission), and Crohn's disease behavior (stricturing/fistulizing). It covers key topics including dietary restrictions, laxative intake instructions, symptom management, and practical problem-solving strategies to improve understanding and adherence to bowel preparation protocols. The video is delivered via WeChat link.
