Study: EMS Helicopters Improve Survivability for Critically Injured
A study from John Hopkins University published in the Journal of the American Medical Association concludes that critically injured patients transported via helicopter to level I or level II trauma centers have a higher chance of survival than those taken by ground transportation. The study covers a total of 223,475 people, spanning 61,909 helicopter-flown patients and 161,566 who received ground transportation. After factoring in “multiple known confounders,” including propensity score matching, the study concludes that a larger percentage of people who experienced “major trauma” had improved odds of survival with a helicopter response (18.2 percent) versus 12.7 percent for ground services.
