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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Enhanced Education Group | Experimental | 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). |
|
| Standard Education Group | Active Comparator | 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Enhanced Education Package for Bowel Preparation | Behavioral | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Boston Bowel Preparation Scale (BBPS) Total Score | 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. | During the procedure itself |
| Measure | Description | Time Frame |
|---|---|---|
| Patient Satisfaction Score | 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. | Within 24 hours after colonoscopy |
| Cecal Intubation Time |

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.
|
|
| Standard Education Leaflet | Other | 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. |

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. |
| During the procedure itself |
| Willingness to Repeat Preparation | Participant-reported willingness to use the same bowel preparation method again, expressed as a binary outcome (Yes/No). | Within 24 hours after colonoscopy |
