Air ambulance service is expensive, however guarantees lifesaving velocity by offering speedy straight-line helicopter transport for critically unwell sufferers.
However a brand new research out of Denmark questions whether or not that costly haste winds up saving extra lives.
Researchers discovered no statistically important distinction within the loss of life fee between individuals transported by floor ambulance or helicopter, in line with findings printed just lately in JAMA Community Open.
That remained true even when researchers solely checked out individuals with vital sickness or accidents. They, too, died at statistically comparable charges.
Analyzing deaths and diseases for critically unwell sufferers, the Danish researchers “discovered there’s not a whole lot of statistical distinction within the general mortality [deaths] between floor and air, in line with this research,” mentioned Dr. Michael Abernethy, chief flight doctor with the College of Wisconsin College of Medication and Public Well being in Madison.
If these findings pan out, it might imply individuals are getting socked with enormous payments for helicopter transport that did not essentially improve their odds of survival.
Practically three out of four air ambulance sufferers are susceptible to being hit with a shock invoice of as much as $20,000 per trip as a result of the transport supplier is not “in community” with their insurance coverage, in line with an earlier Could 2020 research within the journal Well being Affairs.
For the brand new research, researchers led by Dr. Karen Alstrup, from Prehospital Emergency Providers in Aarhus, Denmark, reviewed 10,618 sufferers transported by both floor or air between 2014 and 2018, evaluating outcomes in each teams.
Denmark is about 17,400 sq. miles, roughly the dimensions of Vermont and Massachusetts mixed, with a inhabitants of 5.eight million. The nation is served by three medical helicopters.
Within the research, 9,480 individuals have been flown by helicopter and 1,138 transported by floor. That included 2,260 sufferers with vital sickness or damage who have been flown and 315 who have been pushed to a hospital.
About 23% of sufferers flown by helicopter died inside one yr of transport, in contrast with 24% of these pushed in an ambulance, researchers discovered.
Among the many critically unwell, 25% died inside one yr of air transport versus 27% with floor transport.
These findings run counter to prior research, which have discovered that transport by helicopter will increase an individual’s possibilities of survival, the Danish researchers famous.
However Abernethy — who wrote an editorial accompanying the research — argues that the Danish researchers did create a good comparability of air and floor transport, as a result of in that nation each modes supply an analogous degree of medical care from skilled personnel.
Additional, the researchers used climate to randomize who obtained air transport, including to the validity of their findings. Dangerous climate pressured some to journey by floor, even when air transport would have been most popular, Abernethy famous.
It is arduous to say how these observations in Denmark would possibly apply to the USA, which provides dramatically various high quality of air and floor ambulance transport relying on the place you reside, mentioned Abernethy and Dr. Jonathan Berkowitz, medical director of Northwell Well being’s Heart for Emergency Providers in New Hyde Park, N.Y.
“Well being care programs range enormously,” Berkowitz mentioned. “I must do a deep dive, however I might not shocked if native issues diminished the generalizability of this research to us. Their present algorithms for choosing transport, kinds of suppliers on groups and sample of sickness might all affect this.”
Abernethy famous that helicopter and floor EMS models can range significantly by way of coaching — each with the aviators and the medical employees.
“In some circumstances you’re delivering the next degree of medical care, and a few circumstances you completely aren’t,” Abernethy mentioned. “You possibly can’t make the blanket assertion that the helicopter crews are at all times higher skilled and have extra expertise than the bottom crews. The bottom crew could have greater medical coaching and extra experience than the medical crew on the helicopter.”
Some components of the nation are also oversaturated with air transport choices, significantly the place insurance coverage reimbursement is extra beneficiant, he added.
“There are some areas of the nation which are so oversaturated, they will have two and even three completely different flight applications sitting on the similar airport, and night time and day distinction between their aviation capabilities and their medical capabilities,” Abernethy mentioned.
Berkowitz mentioned he’d wish to see extra comparability research that have a look at outcomes aside from loss of life — for instance, neurological standing, size of keep in an intensive care unit, or how lengthy it takes an individual to be discharged from the hospital.
“There’s extra that we do not know on these points than what we do know,” Berkowitz mentioned.
The Brookings Institute has extra on air ambulance costs.
