Objective We retrospectively investigated the actual conditions of burn patients evacuated by helicopter in comparison to those evacuated by ground ambulance using the Japan Trauma Data Bank. Methods This study was a retrospective analysis of the data recorded in the Japan Trauma Data Bank between January 2004 and May 2019. After propensity score matching for the method of transportation, the survival rate was compared between the 2 groups. Results During the investigation period, there were 4,627 burn patients (helicopter group, n = 276; ambulance group, n = 4,351). After propensity score matching, there were no significant differences between the 2 groups in any of the assessed variables, and the survival rate did not differ to a statistically significant extent. Conclusion After propensity score matching, the survival rate of the helicopter group did not appear to be superior to the ambulance group. Further prospective studies are needed to explore the proper indications for air transportation of burn patients, which could potentially improve outcomes.
