Helicopter vs. ground-based transfer for emergency interhospital transportation: A time and cost-efficiency analysis across varying transfer distances.

Background: Emergency interhospital transfer can be conducted using either ground-based emergency medical services (GEMS) or helicopter emergency medical services (HEMS). The choice between these modes of transportation relies mostly on urgency and transfer distances, however they are further influenced by road traffic, weather and resource availability. While some studies suggest that HEMS may improve survival rates for severely injured patients, the time efficiency of HEMS versus GEMS across varying distances remains underexplored.
