Trial Outcomes & Findings for Split Dose Golytely With Amitiza Pretreatment Versus Split Dose Golytely Plus Placebo in Outpatient Colonoscopy (NCT NCT00611442)

NCT ID: NCT00611442

Last Updated: 2012-11-01

Results Overview

Bowel cleansing was evaluated with the Ottawa bowel preparation scale by each endoscopist during the endoscopy. Neither the endoscopist nor the endoscopy nurse was aware of the bowel preparation used prior to the colonoscopy. The Ottawa bowel preparation scale is a validated tool and was used in this study to provide a reliable quality assessment of the bowel preparation used for colonoscopy. This validated scale rates each section of the colon, the right, the mid, and the rectosigmoid colon, on a 5-point scale (0-4), as well as a global 3-point rating for overall colonic fluid (0-2). The total score ranges from 0 to 14. An excellent preparation with little fluid would score 0-3, a good preparation 4-6, while scores higher than 7would indicate progressively worsening bowel preparations. A completely unprepared colon would score 11-14, depending on the amount of colonic fluid

Interval 3.0 to 12.0

SECONDARY outcome

Timeframe: measured after completion of the bowel preparation and prior to the colonoscopy, completed during the course of the study (approximately 4 month period)

The participants completed a survey prior to the colonoscopy that graded their overall satisfaction with the bowel preparation. The subjects rated the survey questions on a 5-point Likert scale where 1 = severely distressing, 2=distressing, 3=bothersome, 4=mild, and 5=none.
