Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients over 18 years old who are scheduled for a colonoscopy and can provide informed consent.
✕Probably not a fit
Patients with severe health conditions, recent surgeries, or those unable to comply with bowel preparation protocols may not benefit from this study.

What this trial studies
This study aims to assess the current bowel preparation protocols and their effectiveness across various hospitals in China, particularly in light of the updated 2023 guidelines. It will identify risk factors that lead to inadequate bowel preparation in patients scheduled for colonoscopy. The study involves developing a standardized questionnaire for data collection, conducting audits of preparation practices, and training healthcare providers on compliance with the new guidelines. Ultimately, it seeks to create a risk prediction model and propose personalized bowel preparation strategies based on individual patient characteristics.
Why it matters
Potential benefit: If successful, this study could lead to improved bowel preparation quality, enhancing the effectiveness of colonoscopy procedures for patients.
How similar studies have gone: While there have been studies on bowel preparation, this specific approach focusing on risk factors and standardization in China is relatively novel.
