Evaluating Video, Written, and Verbal Instruction Methods to Improve Bowel Preparation Quality for Outpatient Colonoscopy at Hospital Sibu

What this Trial Is About

Researchers are evaluating how different methods of patient education affect the quality of bowel preparation before outpatient colonoscopy procedures. The study compares three approaches usual verbal counseling by healthcare staff, a written tri-lingual educational pamphlet, and instructional videos accessed via smartphone QR codes. This trial aims to identify which education method leads to better bowel cleanliness as measured by the Boston Bowel Preparation Scale BBPS, improving patient comfort and clinical outcomes while reducing cancellations and waste. Participants are randomly assigned to one of three groups. The control group receives standard verbal instructions and pharmacy information for a split-dose polyethylene glycol PEG 3L bowel preparation. The second group gets a detailed tri-lingual pamphlet plus brief verbal explanation. The third group accesses short, structured videos via QR codes alongside brief verbal guidance. All groups follow the same bowel prep solution and timing protocol. The study is conducted in an outpatient endoscopy unit, with endoscopists and nurses blinded to group assignments. During the study, participants undergo colonoscopy with evaluations of bowel preparation quality using the BBPS at the start of the procedure. Researchers also track polyp detection rates, procedure times, cancellations, repeat procedures, patient tolerance, complications, clarity of instructions, and anxiety levels. Participants must have access to a smartphone or computer for video access and provide informed consent. The study runs from March to August 2026, aiming to improve supportive care for colonoscopy patients.
