Summary
Improving trauma care in developing nations requires a focus on prehospital and emergency room services. Most trauma deaths occur before reaching the hospital, highlighting the need for better emergency medical services (EMS) and early interventions.
Area of Science:
- Global Health
- Trauma Surgery
- Emergency Medicine
Background:
- Organized trauma care systems reduce mortality in high-income countries.
- Trauma system development is underdeveloped in many developing nations.
- This study identifies critical areas for trauma system improvement in developing countries.
Purpose of the Study:
- To compare trauma care outcomes in cities with varying economic levels and emergency medical services (EMS).
- To identify specific areas needing improvement in trauma systems within developing nations.
- To inform targeted interventions for reducing trauma mortality globally.
Main Methods:
- Comparative analysis of seriously injured adult patients (Injury Severity Score ≥9 or deceased) over one year.
- Inclusion of three cities: Kumasi (low-income, no EMS), Monterrey (middle-income, basic EMS), and Seattle (high-income, advanced EMS).
- Data collection included hospital records, prehospital deaths (vital statistics/surveys), and hospital budgets per bed.
Main Results:
- Mortality rates decreased with increasing economic level: Kumasi (63%), Monterrey (55%), Seattle (35%).
- Prehospital deaths were the primary driver of mortality differences, with Kumasi (51%), Monterrey (40%), and Seattle (21%) showing significant field deaths.
- Prehospital times were longest in Kumasi (102 min) and shortest in Seattle (31 min); emergency room mortality was highest in Monterrey (11%).
Conclusions:
- The majority of trauma deaths occur prehospital, emphasizing the universal importance of injury prevention.
- Low- and middle-income nations should prioritize enhancements in prehospital and emergency room care.
- Middle-income nations with existing EMS particularly benefit from improved emergency room interventions.
