A Predictive Model for Inadequate Bowel Preparation Before Colonoscopy: Development and Validation

About 30% of patients were reported to suffer inadequate bowel preparation.

Risk factors, such as diabetes, constipation, history of intra-abdominal or pelvic surgery, etc, have been demonstrated to be important predictors for inadequate bowel preparation. The aim of the study is to create and verify a predictive model for inadequate bowel preparation in Chinese.
