NCT07582731

Brief Summary

This single-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. 300 IBD patients will be randomized 1:1 to standard education plus subtype-specific video education (intervention) or standard education alone (control). Primary outcome: Boston Bowel Preparation Scale (BBPS) score.

Outcome Measures

Primary Outcomes (1)

  • Bowel Preparation Quality (Boston Bowel Preparation Scale, BBPS)

    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.

    Periprocedural (during colonoscopy)

Secondary Outcomes (8)

  • Adequate Bowel Preparation Rate

    Periprocedural (during colonoscopy)

  • Excellent Bowel Preparation Rate

    Periprocedural (during colonoscopy)

  • Cecal Intubation Rate

    Periprocedural (during colonoscopy)

  • Cecal Intubation Time

  • Bowel Preparation Compliance Rate

    After bowel preparation and before colonoscopy (assessed on the day of procedure)

  • +3 more secondary outcomes

Study Arms (2)

Intervention Group (Active Video Education Group)

EXPERIMENTAL

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: 150.

Behavioral: Disease Subtype-Based Active Video EducationBehavioral: standard bowel preparation education

Control Group (Conventional Education Group)

ACTIVE COMPARATOR

Patients receive only standard bowel preparation education, including unified written instructions and a 10-minute verbal explanation, with no additional video education. Sample size: 150.

Behavioral: standard bowel preparation education

Interventions

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.
