Impact of Reinforced Education by Video on the Quality of Bowel Preparation

Not Applicable

• Conditions: Bowel Preparation Scale; Adenoma Detection Rate
• Interventions: Other: Standard preparation instructions; Other: Video

• Registration Number: NCT03185299
• Lead Sponsor: Changhai Hospital

Brief Summary

High quality bowel preparation is essential for successful colonoscopy. This study aimed to assess the impact of reinforced education by Video on the quality of bowel preparation. This prospective, endoscopist-blinded, randomized, controlled study was conducted. Reinforced education groups received additional education via reminders by video 2 days before colonoscopy. The primary outcome was the quality of the bowel preparation according to the Boston Bowel Preparation Scale (BBPS). The secondary outcomes included polyp detection rate (PDR), adenoma detection rate (ADR), tolerance, and subjective feelings of patients.

Arm && Interventions

Group	Intervention	Description
Standard preparation instructions	Standard preparation instructions	The control arm will receive written instruction on preparing for a colonoscopy per standard of care
Video	Video	Patients randomized to the intervention arm will be contacted 48-72h before their procedure via telephone using a standardized script and will be provided a link to a website allowing posting of videos for public viewing

Primary Outcome Measures

Name	Time	Method
Boston Bowel Preparation Scale	2 days	The primary end point of the study was adequate bowel prepara- tion quality de ned as a BBPS total score of ≥6 with all segment scores ≥2

Secondary Outcome Measures

Name	Time	Method
Polyp detection rate	2 days	Secondary end points included polyp detection rate which would be higher in the colonoscopy with satisfactory bowel preparation.
Adenoma detection rate	2 days	Secondary end points included adenoma detection rate which would be higher in the colonoscopy with satisfactory bowel preparation.
