Pre-procedure Modle Predicts Bowel Preparation Quality Prior Colonoscopy

November 8, 2019 updated by: Yanglin Pan, Air Force Military Medical University, China
Bowel preparation is closely llined 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. Thus, it is important to set up a model to predict the quality of bowel preparation individually.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Training cohort
This cohort was used to establish the bowel preparation score (BPS).
Other: Questionnaire
Patients were asked to complete a questionnaire before colonoscopy. Bowel preparation was subsequently assessed by single endoscopist in each center using Boston bowel preparation quality score (BBPS). Both univariate and multivariate logistic regression models were used to identify high-risk factors associated with IBP and a predicting model with the bowel preparation score (BPS) was developed in the training cohort.
Validation cohort
This cohort was used to verify the bowel preparation score (BPS).
Other: Questionnair
Patients were asked to complete a questionnaire before colonoscopy. The predicting modle established by the training cohort will be used to assessing the preparation of validation cohort. The result will compared with endoscopists assessment of preparation.
