Improving Bowel Preparation With an Educational Video

Phase 3

Completed

• Conditions: Bowel Preparation
• Interventions: Other: Written instructions; Other: Educational video

• Registration Number: NCT01099553
• Lead Sponsor: Boston Medical Center

Brief Summary

The investigators goal is to improve bowel preparations with an educational video on the Center for Digestive Disorders (CDD) website that explains the steps required for bowel preparation for those patients undergoing screening colonoscopies. The video will focus on explaining the purpose of a screening colonoscopy, the rationale for bowel preparation, the pre-colonoscopy diet, and the instructions for completing the laxative. In a randomized fashion, patients in the control group will receive the standard written bowel preparation instructions, while patients in the intervention group will receive standard written instructions plus a link to watch the instructional video. The investigators hypothesize that an educational tool that provides visual examples of a good and poor preparation, examples of the pre-colonoscopy diet, and an explanation of how to administer the laxative will lead to improved patient compliance and a better bowel preparation. In addition, the investigators hypothesize that a better quality bowel preparation will improve detection of colonic polyps and fewer recommendations for repeat colonoscopy based solely on inadequate bowel preparation.

Arm && Interventions

Group	Intervention	Description
Standard preparation instructions	Written instructions	The control arm will receive written instructions on preparing for a colonoscopy per standard of care at Boston Medical Center
Interventional	Educational video	The investigational, or experimental arm, will receive standard written instructions on preparing for a colonoscopy plus instructions asking them to watch an educational video on the Center for Digestive Disorders website

Primary Outcome Measures

Name	Time	Method
Quality of bowel preparation	Day of colonoscopy only	The primary outcome will be the endoscopist's assessment of the quality of preparation using a standardized bowel preparation scale

Secondary Outcome Measures

Name	Time	Method
Patient compliance	Day of colonoscopy only	Patient compliance with preparation instructions self-reported in a pre-procedure questionnaire
Histology of polyp	one week after colonoscopy	number of adenomatous polyps
Colonoscope insertion and withdrawal times	Day of colonoscopy only	time from insertion to cecum and time from cecum to anus
Preparation associated side effects	Day of colonoscopy only	Presence and severity of preparation associated side effects including: blaoting, abdominal pain, and nausea/vomiting
Patient satisfaction	Day of colonoscopy only	patient's perception of the helpfulness of the video as self-reported on a pre-procedure questionnaire.
Number of repeat colonoscopies due to inadequate bowel preparation	Day of colonoscopy only	Blinded endoscopist's assesment about the need for a repeat colonoscopy due to inadequate bowel preparation
