Brief Summary

The goal of this clinical trial is to learn about bowel preparation methods compared between standard techniques and enhanced education with application for elective colonoscopy. The main questions it aims to answer are: Which bowel preparation method results in an adequate bowel preparation rate? Participants will:

• Random to 1:1 ratio to be educated via the smartphone application (APP group) or the standard education (control group).
• Received the same purgative regimen and diet restriction.
• Endoscopist-blinded colonoscopy the participants and give score of bowel preparation scale (use Boston Bowel Preparation Scale)

Conditions

Colonoscopy; Bowel Preparation; Quality; Smartphone Application

Keywords

Colonoscopy; Smartphone application; Bowel preparation; Quality

Outcome Measures

Primary Outcomes (1)

• Quality bowel preparation rate

  Quality bowel preparation will evaluated by Boston Bowel Preparation Scale score that over 6 points.

  The 1 day of colonoscpy

Secondary Outcomes (6)

• Colonoscopy quality indicators : withdrawal time

  During the colonoscopy

• Colonoscopy quality indicators : polyp detection rate

  During the colonoscopy

• Colonoscopy quality indicators : adenoma detection rate

  During the colonoscopy and following the pathological result

• Colonoscopy quality indicators : cecal intubation time

  During the colonoscopy

• Patient satisfaction

  On the day of colonoscopy

Study Arms (2)

Control group

NO INTERVENTION

Patients in the control group received verbal instructions for bowel preparation before endoscopy from the endoscopy nurse, along with pamphlets containing relevant information. This instructional material encompassed details regarding a purgative regimen, instructions on its administration, dietary restrictions preceding colonoscopy, and medication adjustments necessary for some patients.

Application group

ACTIVE COMPARATOR

Patients in the application group will be communicated via Line applications (APP group) with guidance on preparation before colonoscopy through video media.

Combination Product: APP

Interventions

APP COMBINATION_PRODUCT

Patients in the application group communicated via Line applications (APP group) with guidance on preparation before colonoscopy through video media.

Also known as: Smartphone application
