About this study
The diagnostic accuracy of colonoscopy depends on the quality of bowel preparation, which is a critical element associated with the diagnostic yield, difficulty, time required, and the completeness of colonoscopy. The non-digestive physicians seemed to have a lower quality of bowel preparation compare to the digestive physicians. Therefore, investigators planned to evaluate the risk factors for suboptimal intestinal preparation in outpatients from the perspective of digestive doctors and non-digestive.

The non-digestive physicians seemed to have a lower quality of bowel preparation compare to the digestive physicians.
