Transferred Patients by Fars Province’s Helicopter Emergency Medical Service (HEMS); A 2-Years Cross-Sectional Study in Southern Iran

To investigate the patients transferred by helicopters, as well as an emergent medical services that were performed for them. Methods: In this retrospective cross-sectional study, all patients who were transferred by Fars province of Helicopter Emergency Medical Services (HEMS) to Shiraz hospitals, southern Iran (March 2017-March 2019) were investigated. Patients’ information was collected and analyzed includes age, gender, dispatch reason, trauma mechanisms, take hold of emergent medical services, as well as the air transportation time, time between dispatch from the origin hospital and starting the procedures, and patients’ outcome. Results: Eighty-three patients were enrolled with the mean±SD age of 36.9±19.47 years that 75.9% had trauma (p<0.0001). Mental status deterioration (25.3%) was the most dispatched indications. The mortality rate was 13.25% totally (11.11% in traumatic vs. 10% in non-traumatic). The mean±SD of air transportation time was significantly lower than ground transportation in both traumatic (p=0.0013) and non-traumatic (p<0.0001) patients. Also, the mean±SD of time between dispatch from the origin hospital and starting the procedures was statistically lower in air transportation in both traumatic (p=0.0028) and non-traumatic (p=0.0017) patients. Conclusion: Most of the patients transferred by HEMS were traumatic. The air transportation time as well as the time between dispatches from the origin hospital to the starting of the procedures were significantly lower in HEMS in comparison with ground transportation for both traumatic and non-traumatic patients.
