External Validation of a Predictive Model for Bowel Preparation in Patients Undergoing Colonoscopy

Completed

• Conditions: Colonoscopy; Bowel Preparation

• Registration Number: NCT04325139
• Lead Sponsor: Air Force Military Medical University, China

Brief Summary

Bowel preparation is closely lined to the quality of colonoscopy, inadequate bowel preparation (IBP) could lead to higher miss rate of adenomas, patients' discomfort and higher health expense. For the patients with possible IBP before the examination, it may be better to cancel the colonoscopy and repeat bowel preparation through modified or enhanced strategies. This study aimed to externally validate the efficiency of a procedure-based model in predicting inadequate bowel preparation
