title: Impact of patient education with cartoon visual aids on the quality of bowel preparation for colonoscopy.
abstract: BACKGROUND
  High-quality bowel preparation is a prerequisite for colonoscopy. Few studies have evaluated visual aids as a means of improving the quality of bowel preparation.
  
  
  OBJECTIVE
  To assess the effect of patient education by using cartoon visual aids on the quality of bowel preparation.
  
  
  METHODS
  An endoscopist-blinded, randomized, controlled trial.
  
  
  METHODS
  Tertiary referral center.
  
  
  METHODS
  Patients scheduled for screening colonoscopy in a health examination center.
  
  
  METHODS
  Patients were assigned to receive the existing verbal and written instructions (group A) or a new cartoon visual educational instruction (group B) for colonoscopy.
  
  
  METHODS
  The primary endpoint was the quality of bowel preparation, assessed by using the Boston Bowel Preparation Scale (BBPS). Secondary endpoints were the quality of bowel preparation assessed by using the Universal Preparation Assessment Scale; insertion, withdrawal, and workup times; and polyp detection rates in the 2 groups. Logistic regression analysis was performed to determine the factors associated with poor bowel preparation according to a BBPS score less than 5.
  
  
  RESULTS
  Group B exhibited better bowel preparation than group A according to BBPS scores (mean BBPS score, 6.12 ± 2.19 vs 7.44 ± 1.87, P ≤ .01; median BBPS score, 6.00 ± 0.00 vs 9.00 ± 0.00, P ≤ .01; good bowel preparation for colonoscopy, BBPS score ≥5, 81.6% vs 93.1%, P = .02). Multivariate analysis revealed that older age (odds ratio 1.07, P ≤ .01) and no use of visual aids (odds ratio 3.08, P = .02) were independent factors associated with poor bowel preparation.
  
  
  CONCLUSIONS
  Single-center study.
  
  
  CONCLUSIONS
  Patient education with cartoons effectively improved bowel preparation for colonoscopy.
