About this study
Our study presents an innovative educational approach combining visual and auditory elements, targeting the specific needs of the geriatric population. Generally, before colonoscopy, participants are given a written instruction describing the standard bowel preparation with the use of laxatives and enemas. In our study, in addition to this written instruction, the investigators aimed to support the bowel preparation procedure with visual training by using an animated video. The use of animated video has the potential to present complex medical instructions in a simple and understandable format. This approach is especially designed for elderly participants who have limited literacy skills or have difficulty in following written instructions. In addition, it was aimed to reduce the anxiety of the participants before the colonoscopy procedure and to increase patient compliance.
Read the detailed description
Colonoscopy is a critical screening method for early detection and prevention of colorectal cancer. However, the success of the procedure largely depends on the quality of bowel preparation. Inadequate bowel preparation may lead to repeated procedures, increased costs, potentially delayed diagnoses and associated poor prognosis. This problem is more prominent especially in the geriatric population over 60 years of age. With the animated video, the investigators aim to improve bowel cleansing before colonoscopy by providing visual and auditory training to participants and/or their carers. This project will both contribute to the improvement of colonoscopy preparation protocols for the geriatric population and potentially provide a model that can be adapted to other age groups.
Animation training video was created collaboratively by Mersin University Faculty of Medicine Department of General Surgery and Mersin University Graphic Arts Department.
The Boston Bowel Preparation Scale (BBPS) is a scoring system designed to assess bowel cleansing during colonoscopy. It provides a standardised, reliable measure to improve the quality and outcomes of colonoscopy procedures. While there are many different scales to measure bowel preparation, the BBPS was selected for use in the study as it is considered to be the most comprehensively validated bowel preparation scale. The BBPS is a 10-point scale that assesses bowel readiness. It assesses three segments of the colon (right, transverse and left) with scores ranging from 0 to 3 for each segment, leading to a total score of 0 to 9.
Using this scale, the investigators tried to determine whether there would be a difference in terms of bowel preparation between participants who watched an animated video and participants who were given standard instructions.

What is being measured
The primary outcome is the main question the study is designed to answer.
Quality of Bowel Preparation
The primary outcome measure of this study is the quality of bowel preparation, which will be assessed using the Boston Bowel Preparation Scale (BBPS). This validated scale will be used to evaluate the cleanliness of each colonic segment during colonoscopy. The BBPS assigns a score of 0 to 3 for each of the three segments of the colon (right colon, transverse colon, and left colon), resulting in a total score ranging from 0 to 9. Adequate bowel preparation will be defined as a total BBPS score ≥ 6 with all segment scores ≥ 2. The assessment will be performed by endoscopists who are blinded to the patient's group allocation to minimize bias. This standardized evaluation will provide an objective measure of the effectiveness of our video-based educational intervention compared to standard written instructions in achieving optimal bowel preparation in the geriatric population.
