Summary
This study analyzed emergency medical services (EMS) in an Asian city, finding trauma as the leading cause. Most patients required basic care, suggesting an EMT-based system could manage most prehospital needs.
Area of Science:
- Emergency Medicine
- Public Health
- Epidemiology
Background:
- Emergency Medical Services (EMS) systems are crucial for prehospital care.
- Understanding the epidemiological characteristics of EMS utilization is vital for resource allocation and system optimization.
- Previous studies have highlighted variations in EMS demand and characteristics across different urban settings.
Purpose of the Study:
- To analyze the epidemiological characteristics of emergency medical services (EMS) utilization in an Asian city.
- To identify the primary reasons for EMS calls and the level of prehospital care required.
- To evaluate the efficiency of the existing EMS system in terms of response and transport times.
Main Methods:
- A prospective citywide cohort study was conducted.
- Data from 5,459 emergency medical services cases were collected and analyzed.
- Epidemiological characteristics, including chief complaints, required care level, and prehospital times, were recorded.
Main Results:
- Trauma was the leading cause of EMS calls (49.7%), with traffic accidents comprising 68% of trauma cases.
- The majority of cases (50%) required no prehospital care, and 16.4% needed advanced life support (ALS).
- Response, on-scene, and transportation times averaged 4.6, 4.3, and 9.4 minutes, respectively, indicating short prehospital times.
Conclusions:
- The studied EMS system demonstrated very short prehospital times and a low incidence of dead on arrival (DOA) cases.
- Given that few patients required ALS care, an emergency medical technician-based EMS system could likely manage the majority of prehospital patients effectively.
- The findings suggest potential for optimizing EMS resource allocation towards a more basic, EMT-driven model for this specific urban context.
