This study evaluated an out-of-hours emergency endoscopy model, finding it effectively improved access and safety for gastrointestinal bleeding patients. The model demonstrated comparable outcomes for direct admissions and transfers, highlighting its efficiency.
Area of Science:
- Gastroenterology
- Emergency Medicine
- Healthcare Management
Background:
- Many countries lack coordinated out-of-hours endoscopy services.
- Economic constraints and resource limitations are key barriers to emergency endoscopy access.
Purpose of the Study:
- To evaluate the performance of an out-of-hours emergency endoscopy model.
- To assess the effectiveness and safety of this model for acute upper gastrointestinal bleeding.
Main Methods:
- Prospective data collection over 3 years (2010-2012) from 332 outpatients with non-variceal acute upper gastrointestinal bleeding.
- Comparison of outcomes between direct admissions and patients transferred from other hospitals.
Main Results:
- 90% of patients received upper endoscopy within 24 hours.
- No significant differences in rebleeding, mortality, or need for surgery between direct admissions and transferred patients.
- Age, malignancy, and high Rockall score predicted in-hospital mortality.
Conclusions:
- The emergency endoscopy model enhanced access and equity for out-of-hours care.
- The model proved effective, safe, and timely, with consistent outcomes across patient groups.
- This approach offers a viable solution for managing emergency gastrointestinal bleeding.
