Most patients are willing to adhere to split-dose bowel preparations for colonoscopy, even for early morning procedures. This high acceptance and compliance suggest split-dosing is a viable option for improving colonoscopy prep.
Area of Science:
- Gastroenterology
- Endoscopy
- Patient Adherence
Background:
- Split-dose bowel preparations are more effective than evening-before regimens for colonoscopy.
- Physician concerns exist regarding patient acceptance of split-dosing for early morning procedures.
Purpose of the Study:
- To assess patient willingness to undergo split-dose bowel preparation for early morning colonoscopies.
- To evaluate actual patient adherence to split-dose bowel preparation instructions.
Main Methods:
- A survey was conducted among patients undergoing esophagogastroduodenoscopy and drivers of colonoscopy patients regarding willingness to accept split-dosing.
- Colonoscopy patients with early morning appointments were surveyed about their compliance with split-dose instructions.
Main Results:
- 85% of surveyed individuals expressed willingness to take a second dose during the night.
- 78% of patients with early morning colonoscopies complied with split-dose preparation instructions.
Conclusions:
- Patient acceptance and compliance with split-dose bowel preparations are high.
- Split-dose regimens should be considered for colonoscopy without concern for patient adherence.
