    PurposeGiven that the benefits of helicopter transport vary with geography and healthcare systems, we assessed transport times for rotor wing versus ground transport over a 10 year period in an urban setting.Materials And MethodsAll completed transports from 153 sending hospitals in New England from 2009 through 2018 to 8 local tertiary care centers were extracted from an administrative database. The primary outcome of interest was patient-loaded transport time for rotor wing versus ground transports. Overall, 25,483 patient transports met the inclusion criteria and were included in this study. We assessed patient-loaded transport time for all transports, and determined mean time to arrive at the scene, scene to patient time, the bedside time, and distance at which the patient-loaded transport time was faster for rotor wing than for ground transport. We also performed subgroup analyses, evaluating transport times by time of day, day of the week, and destination.ResultsThe most common indication for transport was adult trauma, (n = 6,008, 23.6%) followed by adult cardiac (n = 4359, 17.1%), adult neuro (3729 14.6%), and adult medical (n = 3691, 14.5%). The median miles traveled for all transports was 26.0, IQR 14-38, ranging from 1 to 264 miles. The median patient-loaded transport time was 27 min (IQR 15-40) for all transports. Nearly all time intervals were shorter for rotor wing versus ground transports, and patient-loaded transport time was significantly shorter at 15 minutes compared to 38 minutes (IQR 12-22 vs 28-33, p < 0.001). There was no distance at which the patient-loaded transport time was faster for ground transport than for rotor wing.ConclusionsIn over 25,000 transports over 10 years, in a compact metropolitan area with relatively short transport distances and times, the use of the helicopter was associated with substantial time savings.
