Trial Outcomes & Findings for Improving Bowel Preparation for Colonoscopy With a Simple Educational Card (NCT NCT00643682)

NCT ID: NCT00643682

Last Updated: 2012-10-01

Results Overview

An ordinal scale. 0=fully unprepared colon and 9=perfectly clean colon. Higher values represent a better outcome. For reference please see: Lai EJ, Calderwood AH, Doros G, Fix OK, Jacobson BC.

SECONDARY outcome

Timeframe: 2 years

The number of times a colonoscopist recommended that the bowel was too unclean to qualify as an acceptable colonoscopy and therefore recommended repeating the procedure after better cleansing. This is both the number of participants with an inadequate preparation and the number of inadequate procedures. These are synonymous.
