Brief summary
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.
Interventions
a multifaceted intervention was designed to improve mechanical bowel preparation (MBP) in patients undergoing colonoscopy. It included: Structured face-to-face counseling on the importance of bowel prep, potential complications of poor prep, and how to follow instructions. A 6-minute instructional video explaining step-by-step dietary and medication instructions. A printed booklet with visual aids summarizing key steps. A mobile phone app delivering interactive reminders, tracking tools, and preparation guidance. All participants used the same polyethylene glycol-based bowel cleansing agent.
Participants in this arm received a standard hospital-issued bowel preparation instruction leaflet. The document provided written instructions on dietary modifications, timing and dosage of the bowel cleansing agent, and day-of-procedure guidance. No personalized counseling, video support, or reminder tools were provided. This reflects the routine care practice at the study hospitals.

Masking description
Endoscopists scoring bowel preparation using the Boston Bowel Preparation Scale (BBPS) were blinded to the participant's group assignment. Participants and care providers were not masked due to the nature of the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Boston Bowel Preparation Scale (BBPS) Total Score | During the procedure itself | The BBPS is a validated scoring system to assess bowel cleanliness during colonoscopy. It ranges from 0-9, with three sub-scores (right, transverse, left colon) each scored 0-3. Higher scores indicate better bowel preparation quality. Total BBPS score will be compared between groups. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient Satisfaction Score | Within 24 hours after colonoscopy | Measured on a 10-point Likert scale, with 1 = very dissatisfied and 10 = very satisfied. Participants were surveyed about their experience with the preparation process. |
| Cecal Intubation Time | During the procedure itself | Time (in minutes) from insertion of the colonoscope to successful intubation of the cecum, recorded by the performing endoscopist. Lower times indicate more efficient procedures. |
| Willingness to Repeat Preparation | Within 24 hours after colonoscopy | Participant-reported willingness to use the same bowel preparation method again, expressed as a binary outcome (Yes/No). |
