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.

Gedetailleerde beschrijving
Inflammatory bowel disease (IBD) patients often have suboptimal bowel preparation before colonoscopy due to chronic inflammation, strictures, and poor adherence to preparation protocols. Conventional written and verbal education has shown limited effectiveness in this population. This multi-center trial will develop and test an active video education intervention tailored to IBD subtypes (ulcerative colitis or Crohn's disease), delivered via WeChat before colonoscopy. A total of 600 patients from 13 participating hospitals across China will be randomized 1:1 to either the intervention group or the control group. Randomization will be stratified by center using a computer-generated sequence with allocation concealment (sealed, opaque envelopes). The primary endpoint is bowel preparation quality measured by the total BBPS score. Secondary outcomes include adequate/excellent preparation rates, cecal intubation rate and time, patient compliance, knowledge scores, adverse events, anxiety levels, and satisfaction. Outcome assessors will be blinded to group assignment to reduce bias. Statistical analyses will account for center effects (e.g., using mixed-effects models or including center as a covariate) and will be performed using appropriate methods based on data distribution.

Experimenteel: Intervention Group (Active Video Education Group)
Patients receive conventional bowel preparation education (written instructions + 10-minute oral explanation) plus disease subtype-specific active video education delivered via WeChat. Patients are required to watch the tailored video at least once within 3 days before colonoscopy. No investigational drug or device is involved. Sample size: 300. |
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.

Bowel Preparation Quality (Boston Bowel Preparation Scale, BBPS)
Tijdsspanne: Periprocedural (during colonoscopy)
|
The Boston Bowel Preparation Scale (BBPS) is a validated scoring system to assess the cleanliness of three colonic segments: right colon (including cecum and ascending colon), transverse colon (including hepatic flexure and splenic flexure), and left colon (including descending colon, sigmoid colon, and rectum). Each segment is scored from 0 (unprepared) to 3 (excellent) by the endoscopist during withdrawal. The total BBPS score ranges from 0 to 9. Higher scores indicate better bowel preparation. |
