Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The rate of adequate bowel preparation is one of important quality indicators of colonoscopy. Inadeqaute bowel preparation negatively affects the outcomes of colonoscopy. If patients with inadequate bowel preparation were identified before the procedure, enhanced strategy could be offerred to achieve better bowel cleasing. Currently, there were three predicting models of inadequate bowel preparation eatablished based on patient-related factors. It remains unclear which model perfroms better in predicting bowel preparation quality. Futhermore, althought those predicting models only composing of patients-related factors are useful for identifing high-risk patients, the preparation-related factors may also be valuable for prediciting inadeqaute bowel preparation before the procedure of colonoscopy.

This study aimed: 1) to compare the values of three availlable models (based on patient-related factors) in predicting inadeqaute bowel preparation in a prospective, multicentered cohort of patients undergoing colonoscopy; 2) to investigate whether a new model based on preparation-related or a combined model based on patient-related and preparation-related factors is comparable to previous models based on patient-related factors.

training group

All patients received oral and written instructions on the appointment day. All patients were instructed to have low-residue food for lunch and dinner on the day before colonoscopy. Patients were instructed to begin drinking the first 1.5L-2L PEG at 7:00-9:00 PM on the day before colonoscopy. On the day of the procedure, they took another 1.5L-2L 4-6 hours before colonoscopy. Patients were encouraged more to drink more clear liquids after purgatives for adequate hydration.
