Impact of Telephone Call on Bowel Preparation Quality in Colonoscopies

Study Overview
=================
Brief Summary
-----------------
Bowel preparation regimens typically incorporate dietary modifications along with oral cathartics. Inadequate bowel preparation can result in failed detection of prevalent neoplastic lesions and has been linked to an increased risk of procedural adverse events. Previous studies have suggested that patient compliance is important to ensure proper bowel cleansing. Patient counseling along with written instructions that are simple and easy to follow and in their native language should be provided to patients. Thus, interventions that improve the quality of bowel preparation could have a great benefit regarding colonoscopy results. Little in the literature that studies the impact of enhanced patient education on bowel preparation quality. In this study we aim to determine the impact of patient education using telephone call one day prior to outpatient colonoscopy on bowel preparation quality.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Bowel preparation quality | We will use Aronchick Scale as bowel preparation quality scale. This scale characterizes the percentage of the total colonic mucosal surface covered by fluid or stool, and is performed before washing or suctioning. This scale grades the adequacy of cleansing in the following: Excellent: Small volume of clear liquid, or greater than 95% of surface seen Good: Large volume of clear liquid covering 5-25% of the surface but greater than 90% of surface seen Fair: Presence of some semi-solid stool that could be suctioned or washed away but greater than 90% of surface seen Poor: Semi-solid stool that could not be suctioned or washed away and less than 90% of surface seen Inadequate: Repreparation needed Bowel preparation will be considered as adequate if the score is ≤ 3 and inadequate if the score of bowel preparation is ≥ 4. | Directly after colonoscopy | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Colonic polyps rate | Detect rate of colonic polyps in both groups | Directly after colonoscopy |
