Hospital-based rotorcraft aeromedical emergency care services and trauma mortality: a multicenter study

Area of Science:

• Emergency Medicine
• Trauma Surgery
• Aeromedical Services

Background:

• Blunt trauma remains a leading cause of mortality.
• Timely and advanced pre-hospital care is critical for trauma patient outcomes.
• Hospital-based rotorcraft aeromedical services provide rapid transport and advanced interventions.

Purpose of the Study:

• To evaluate the impact of hospital-based rotorcraft aeromedical emergency care services on mortality in blunt trauma patients.
• To assess the effectiveness of these services in reducing predicted mortality based on injury severity.

Main Methods:

• A retrospective study of 1,273 blunt trauma patients treated and transported by seven hospital-based rotorcraft aeromedical services.
• Utilized an injury severity methodology to predict patient mortality.
• Compared predicted mortality with actual observed mortality.

Main Results:

• The study predicted 241 deaths, but only 191 occurred, representing a 21% reduction in expected mortality (P < .001).
• Five of the seven aeromedical services showed a statistically significant reduction in predicted mortality (P < .05).
• This reduction in mortality was observed across 86% of the total patient cohort.

Conclusions:

• Hospital-based rotorcraft aeromedical emergency care services are associated with a significant reduction in expected mortality for blunt trauma patients.
• These services demonstrate effectiveness in improving outcomes for severely injured patients requiring rapid transport.
• The findings support the continued use and development of aeromedical services in trauma care systems.
