About

The goal of this clinical trial is to learn whether enhanced education and counseling can improve bowel preparation before colonoscopy in high-risk patients. The main questions it aims to answer are:

Does enhanced education lead to better bowel cleansing as measured by the Boston Bowel Preparation Scale (BBPS)?

Does it improve patient satisfaction, compliance with instructions, and procedure efficiency?

Researchers will compare an enhanced education program (including counseling, video, booklet, and mobile app) to standard written instructions typically given before colonoscopy.

Participants will:

Be randomly assigned to either the enhanced education group or the standard instruction group

Undergo routine colonoscopy after following the assigned preparation method

Complete short questionnaires about their experience, satisfaction, and willingness to repeat the process

This study is being done at two hospitals in Palestine.

Enhanced Education Group

Experimental group

Description:

Participants in this group received enhanced bowel preparation education. The intervention included: Face-to-face counseling by trained staff about the importance of bowel prep and how to follow instructions; A 6-minute instructional video explaining dietary restrictions, purgative usage, and procedure timeline; A printed booklet with illustrated step-by-step instructions; and Access to a smartphone app with automated reminders, preparation tracking, and guidance. All participants used the same bowel cleansing agent (polyethylene glycol-based preparation).

Treatment:

Behavioral: Enhanced Education Package for Bowel Preparation

Other: Standard Education Leaflet

Standard Education Group

Active Comparator group

Description:

Participants in this group received standard bowel preparation instructions in the form of a hospital-issued informational leaflet. This leaflet included basic written instructions about dietary restrictions, timing and method of laxative use, and preparation day logistics. No counseling, video, or app-based support was provided. The same bowel cleansing agent was used in both arms.
