Access performance in an emergency medical service system

Summary
Emergency Medical Service (EMS) access delays are often caused by non-transportation factors, not proximity to care facilities. Improving discovery, notification, and dispatch is key to faster emergency response times.
Area of Science:
- Emergency Medicine
- Public Health Systems
- Transportation Safety
Background:
- Emergency Medical Service (EMS) access is critical for patient outcomes.
- Understanding delays in EMS response is essential for system improvement.
- Previous analyses have not fully differentiated performance of EMS access components.
Purpose of the Study:
- To analyze the relative performance of EMS "access components": discovery and notification, dispatch, and transportation.
- To identify factors contributing to prolonged EMS access delays.
Main Methods:
- Combined data from the Illinois Trauma Registry and Illinois Department of Transportation.
- Analyzed EMS incidents based on proximity to care facilities and access delays.
- Differentiated delays attributed to transportation versus non-transportation components.
Main Results:
- Most EMS incidents occurred near care facilities with reasonable access delays.
- A subset of "problem incidents" experienced significant delays despite close proximity.
- Non-transportation components (discovery, notification, dispatch) were primary drivers of delays in problem incidents.
Conclusions:
- EMS access system performance is significantly impacted by non-transportation elements.
- Targeted improvements in discovery, notification, and dispatch can reduce critical access delays.
- Optimizing the entire EMS access pathway, not just transportation, is crucial for enhancing emergency medical response.
