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

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

Other

Before colonoscopy, the following information was obtained by the colonoscopists through asking patients: the characteristics of last stool, the time of drinking first dose of laxative, the time of first defecation, the time of drinking last dose of laxative. The beginning time of colonoscopy was also recorded. During withdrawal phase, the quality of bowel preparation was evaluated based on BBPS scale.

Primary outcomes

Adequate bowel preparation

Time frame: 1 hour

Defined by each segmental BBPS≥2

Secondary outcomes

The rate of yellow, clear stool in the last defecation

Time frame: 1 hour

The characteristics of the last stool was self-evaluated by patients based on a picture containing different kind of stool examples.
