Bowel Preparation Quality, Colonoscopy, Patient Education

Brief 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.

Detailed description

Colonoscopy is a standard procedure performed for the evaluation of gastrointestinal symptoms, colorectal cancer screening, polyp detection, and polyp removal. Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States , and in Türkiye, 21,718 new cases were reported in 2022. These statistics underscore the importance of colonoscopy as a preventive and diagnostic tool. When conducted properly, colonoscopy is safe and well-tolerated, allowing visualization of the entire colon and distal terminal ileum. The procedure's optimal effectiveness relies heavily on patient compliance with bowel preparation instructions. Unfortunately, inadequate bowel preparation occurs in approximately 20-25% of colonoscopies, often due to non-adherence, medical conditions affecting bowel cleansing, or prolonged waiting times for the procedure. While interventions addressing medical conditions or waiting times may not always be feasible, non-compliance with preparation instructions represents a modifiable, patient-related factor. Effective bowel preparation requires adherence to dietary recommendations and the use of prescribed laxatives. The quality of preparation impacts examination adequacy, procedure duration, cancellation rates, and the need for repeat colonoscopies. Inadequate preparation can hinder thorough evaluation, prevent detection of precancerous lesions such as polyps, and increase healthcare costs. Emerging evidence suggests that video-based educational interventions are more effective than traditional written or verbal instructions, phone calls, social media applications, or messaging services in improving patient compliance and bowel preparation quality. This study aims to assess the effect of video-based education on bowel preparation before colonoscopy. By evaluating its impact on preparation quality and patient adherence, the study seeks to provide evidence for implementing more effective educational strategies in colonoscopy units, thereby optimizing clinical outcomes and resource utilization.

Interventions

BEHAVIORALVideo 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.

Intervention model description

Participants will be randomly assigned to either a video-based education group or a control group receiving standard written and verbal instructions. Both groups will be followed in parallel to assess the effect of the intervention on bowel preparation quality before colonoscopy.

Design outcomes

Primary

MeasureTime frameDescription
Quality of Bowel PreparationDay of ColonoscopyThe 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.
