A nationwide survey of civilian air ambulance services

To identify and characterize civilian air ambulance services, a questionnaire was mailed nationwide to 583 prospective air ambulance services, with 154 responding. Our survey identified differences between hospital, hospital-affiliated, and private air ambulance services as to aircraft ownership, availability, types of aircraft, types of patients being transported, types of medical personnel and equipment, aircraft retrofit, and their feelings regarding air ambulance regulations. We found that hospital air ambulances are better suited for transporting critically ill patients while many private air ambulances appear better suited to transport nonemergency patients. Hospital-affiliated air ambulance services, although not as consistent in providing the specialized care of hospital air ambulances, appear better able to provide critical care than private air ambulance services. Based upon this data, we recommend that air ambulance regulations be directed at levels of patient care. Such regulations and guidelines will assist patient safety during aeromedical transports without jeopardizing currently operating air ambulance services.
