“…7,11,12,23,24 These studies, largely relying on multi-institution databases, have demonstrated that helicopter transport when compared with ground transport is protective against mortality. 7,8,11,12,32 In the second iteration of our multivariable model, where we included ISS, RTS, and highest AIS, we found the same results. Risk adjustment is necessary to reduce the confounding caused by patients with minor injuries who are likely to be transported only by ground and, thus, would otherwise make it appear that ground transport protects against mortality.…”

“…We do know that aeromedical transport accounts for only 3% of all trauma transports and therefore should not invalidate our results. (32) Additionally, we did not account for EMS response and dispatch time, because we assumed that EMS activation time was constant throughout the study.…”

“…The rapid growth of predominantly civilian air medical services has been uncoordinated and driven by local demand for advanced trauma care or improved access to a tertiary care facility. 13 Whereas the percentage of a state population covered by a 10-minute fly circle is only 10% in Vermont, that in Maryland and Delaware is 98%. 14 This geographical variability was demonstrated in this study as well.…”

“…11 Because there is significant regional variability in medical care and there has been a rapid emergence of new HEMS programs across the United States, we predicted that the presence of other HEMS programs in a certain region may impact whether a program independently carries blood. [12][13][14] The purpose of this study is to describe the prevalence and characteristics of HEMS programs that carry blood products during transports in the United States.…”
