A Validated Educational Video Intervention Improves the Quality of Bowel Preparation for Colonoscopy

Study Overview
=================
Brief Summary
-----------------
The investigators hypothesised that a video based patient education will help patients understand the process of colon cleansing prior to a colonoscopy procedure and hence will result in clean colons that will may help physician perform a better quality examination.

Detailed Description
-----------------
After obtaining consent over phone, the investigators randomly assigned assigned participants to receive either the standard paper based instructions or receive an educational video in addition to the standard paper based instruction. Physicians performing the procedure were blinded to this assignment. The investigators obtained information relating to the cleanliness of the colon as noted during the colonoscopy examination. The investigators obtained this information from the colonoscopy reports. The investigators also obtained information regarding colon polyps,wanting to see if there is any difference in the number of patients in whom adenomatous polyps were detected. Outcome measures: Primary Out come: 1.Quality of bowel preparation Secondary outcome: Adenoma detection rate Rate of incomplete procedures due to poor bowel prep.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Instructions printed on a paper.<br>There will be no intervention. | |
| Experimental: Paper and video instructions<br>.Instructions printed on paper and a educational video. | Other: Educational video<br>* An educational video was developed based on the current paper instructions for bowel preparation. The video included a physician explaining the process, using more images and short clip videos of the example. The script of the video was approved by the patient education department of the University Hospital and language adjusted to 6th grade level.<br>|
