The Effect of Video-Based Education on Colonoscopy Preparation

Condition(s) studied

Investigational drug(s) / intervention(s)

Video Education: Participants receive routine written and verbal instructions about colonoscopy preparation, including dietary instructions and use of prescribed laxatives. This represents the standard care provided at the study site.

Study summary

Colonoscopy is a routine procedure for evaluating gastrointestinal symptoms, detecting colorectal cancer, and removing polyps. Its effectiveness depends on patient compliance with bowel preparation instructions. However, inadequate bowel preparation occurs in 20-25% of colonoscopies, often due to non-adherence, medical conditions, or long waiting times. Poor preparation can reduce examination quality, prevent detection of precancerous lesions, and increase healthcare costs. Video-based education has been shown to be more effective than written or verbal instructions in improving bowel preparation. This study aims to evaluate the effect of video-based education on colonoscopy bowel preparation and contribute evidence to optimize patient compliance.

Eligibility

Primary outcome measure(s)

• Quality of Bowel Preparation — Day of Colonoscopy
  The quality of bowel preparation will be assessed on the day of colonoscopy using the Boston Bowel Preparation Scale (BBPS). This scale evaluates cleansing in three segments of the colon. Higher scores indicate better preparation, reflecting patient compliance with dietary and laxative instructions and the effectiveness of the educational intervention.
