The benefits of air transport have been demonstrated to outweigh any stressors that flying might add, even for the sickest trauma and heart attack patients.
Most air medical transports today are between hospitals i.e hospital to hospital; approximately one-third are scene responses e.g for a car accident or major incident and the remainder are other types (e.g., organ procurement and specialty/neonatal/pediatric team transport).
The ability to focus specialty healthcare resources into fewer highly committed specialty hospitals using air ambulance services provides a volume base which assures expertise and reduces the cost of redundant, low volume, services in a specific geographic area.
