Something to think about in light of last week's accident.

 

When birds can’t fly: An analysis of interfacility ground transport using advanced life support when helicopter emergency medical service is unavailable

BACKGROUND Helicopter emergency medical service (HEMS) transport of trauma patients is costly and of unproven benefit. Recent retrospective studies fail to control for crew expertise and therefore compare highly trained advance life support with less-trained basic life support crews. The purpose of our study was to compare HEMS with ground, interfacility transport while controlling for crew training. We hypothesized that patients transported by HEMS would experience shorter interhospital transport time and reduced mortality.

METHODS Our National Trauma Registry of the American College of Surgeons database was retrospectively queried to identify consecutive interfacility, hospital transfers (January 1, 2008, to November 1, 2012) to our Level I trauma center. Transfers were stratified by transportation vehicle (i.e., HEMS vs. ground transport). Cohorts were compared across standard demographic and clinical variables using univariate analysis. Multivariate logistic regression was performed to determine the association of these variables with mortality.

RESULTS The HEMS (n = 2,190) and ground (n = 223) cohorts were well matched overall, with no significant differences for demographics, injury severity, physiology, hospital length of stay, or complications. Median (interquartile range) time to definitive care was significantly lower for HEMS (150 [114] minutes vs. 255 [157] minutes, p < 0.001), without change in mortality (9.0% vs. 8.1%, p = 0.71). Multivariate logistic regression did not identify an association between transport mode and mortality.

CONCLUSION Despite faster interfacility transport times, HEMS offered no mortality benefit compared with ground when crew expertise was controlled for, contradicting recent large, retrospective National Trauma Data Bank studies. Our study may represent the best approximation of a prospective study by focusing on patients deemed worthy of HEMS by referring providers. Although HEMS may seem intuitively beneficial for time-dependent injuries, larger studies with a similar methodology are warranted to justify the cost and risk of HEMS and identify subsets of patients who may benefit.

LEVEL OF EVIDENCE Prognostic/epidemiologic study, level III.

Mortality shouldn't be the only measure.

Also considered should be reduction in long and short term injury recovery, reduction in severity of, and number of permanent injuries.

And, for those organ donors like motorcylce riders, geting their organs toa processing location faster.

My intuition tells me that HEMS/HAA will show positive comparison to ground transport.

not the patient.  There is no argument that an ALS crew using a helicopter to transport a patient would provide a higher level of care than a BLS crew using ground transportation. 

I firmly believe every aircrew has, in the back of their mind, "if things start to look bad" we can always turn around before we get in over our head. The truth is, at that point, you are already in over your head.  

If the commitment to continue cannot be made with a 100% resolution, it has to be a non event.  In other words, until the profit motive is removed from the matrix, the insanity will continue.  History will repeat itself.

A BLS crew?  Really?  You are truly mistaken.  Now, another ALS crew vs helicopter might be a fair comparison but a BLS crew will kill someone in a heartbeat.

Tired, stupid, distracted, impaired, incompetent to begin with. And then there's the flight risk itself. As proven many times over the past 35 years. Not looking forward to the day that I'm the one laying on the flat, looking up.

In addition, most studies are tailored to meet the personal agenda of the writer/publisher.

This is very subjective due to the mere fact it has been and continues to be arguable from both sides.

I would present that the medical care in any air ambulance operation is far superior to the [no insult intended] BLS and ALS ground units. The level of mere educational requirements are well exceeded from ground transport systems; not to mention the experience required to move into the HAA arena.

We knew you were a blockhead after the first post. Now make some more self-serving know-it-all comment so even more people find you annoying, boring, and obtrusive. Why should just co-workers and relatives and people in line behind you at WalMart feel that way?

the reason you don't see a big rush to operate ground vehicles with HEMS quality med personnel and equipment. 

I've often wondered why someone wouldn't offer this type of service as the operating costs would seem to favor ground transport.  The only reason that makes sense is that the turn-around times would be too great.

morbidity is THE thing.  Sure, mortality is the big deal, but morbidity is the most expensive by far for all concerned.  Once the latter is started to be measured (somehow) I suspect HAA will be more relevant than the results of the study.

This is truly a complicated issue. Air versus ground depends on injury, population density, central place distances, regional economics, etc.

The bottom line is air was primarily introduced, by hospitals, to fill beds. The good old profit motive. The cost of the transport is easily offset by the cost of hospitalization for traumatic injuries.

I know, on a personal level, that if you are injured and hurting you want to get to the hospital as fast as possible. A 10 minute helicopter ride seems far more preferable than a 50 minute ride on rubber tires. I will say, in some of the moderately remote areas I've worked, if the ground ambulance crew headed straight for the hospital their enroute times are comparable to the time necessary to transfer from the ground ambulance to the air ambulance and then transport.

I guess what I'm saying is that, studies aside, if hospitals profit more from using air transport there will always be a place for HEMS.

Pretty much sums it up.  The helicopter is not an asset to the hospital, it is a liability.  A once large hospital group in Phoenix terminated their contracts for helicopter transport when an audit showed they were not a core asset, and transport to the hospital continues to occur through stand alone providers.  The burden now falls on those ambulance providers be they air or ground, which is why the bill for transport makes it to your house, even before you are discharged from the hospital.
