Helicopter transport and blunt trauma mortality: a multicenter trial

Area of Science:

• Emergency Medicine
• Trauma Surgery
• Transportation Safety

Background:

• The efficacy of helicopter transport in reducing trauma mortality remains a subject of ongoing scientific discussion.
• Existing research presents conflicting evidence regarding the benefits of air medical services for critically injured patients.

Purpose of the Study:

• To investigate the association between helicopter transport and mortality rates in trauma patients.
• To clarify the role of air medical services in improving patient outcomes following severe injury.

Main Methods:

• A retrospective analysis of trauma registry data from five Level I trauma centers.
• Logistic regression modeling was employed to assess the impact of helicopter transport on mortality, controlling for key patient and transport variables.
• Included factors: age, sex, transport year, receiving hospital, prehospital care level, Injury Severity Score (ISS), and mission type (scene vs. interfacility).

Main Results:

• The study included 16,699 trauma patients.
• Crude mortality was 9.4% for helicopter transport versus 3.0% for ground transport, a 3.4-fold increase.
• Adjusted analysis revealed that helicopter transport was significantly associated with a reduction in mortality (OR, 0.76; 95% CI, 0.59-0.98; p = 0.031).

Conclusions:

• Findings suggest an association between helicopter transport and increased survival for blunt trauma patients.
• The study supports the utility of air medical services in enhancing outcomes for severely injured individuals.
