Flying somewhere this summer? Great! A new study, just
published in the
New England Journal of
Medicine, says the odds of having an in-flight medical emergency are rare.
(“
Outcomes of Medical Emergencies on Commercial Airline Flights,”
New England Journal of Medicine, May 30, 3013.)
According to the study, 2.75 billion passengers fly
worldwide every year. The authors of the study analyzed records from all calls
to a medical communications center from five large domestic and international airlines,
which together represent about 10% of global flight passengers. After analyzing
the data from more than 7 million flights, they categorized the number and the
type of medical emergencies as well as their outcomes (whether or not the
passenger had to go to the hospital after landing, whether they were admitted,
etc.).
The study shows good news. Medical emergencies are rare,
occurring on only 1 out of every 604 flights, affecting only 16 out of every 1
million passengers. According to the authors, “the most common medical problems
were syncope [fainting] or presyncope (37.4%), respiratory symptoms (12.1%),
and nausea or vomiting (9.5%).”
Allergic reactions were about half-way down the list, lower
than cardiac symptoms and seizures. Allergic reactions accounted for only 2.2%
of the medical emergencies – that’s just 2.2% of the 16 out of a million
passengers. So out of the estimated 744 million airline passengers analyzed during
the study period, there were a total of 11,920 medical emergencies reported,
and only 265 of them were an allergic reaction. (It doesn’t break down “allergic
reactions” into causes, so we don’t know how many were caused by food
allergies, environmental allergies, or other.)
And of those 265 allergic reactions, only 12 required the
aircraft to be diverted, 40 required transport to a hospital, and only 8 were
actually admitted to the hospital. Here’s the best part: there were zero (0)
deaths caused by an allergic reaction on the plane.
Remember, that’s out of 744 MILLION total passengers studied
during that time frame.
So… airplanes are scary. Peanuts on airplanes are even
scarier. But if you consider how many people with food allergies fly every year
(and we’re one of those families), these numbers were actually really
surprising to me – I thought they would be a lot higher. I actually have an
adult friend who had a food allergy reaction on a plane once, so I know it
happens. But I’m surprised at how seldom it happens, according to this study. (And
my friend knew nuts didn’t agree with her, but had never had a serious reaction
before the airplane incident, so she wasn’t as prepared as she might have been
had she known.)
What I would love to see now is a study that is more specific to food allergic passengers. I'd like to see how many food-allergic people have flown on airplanes during a particular time period, and then see the percentage of THOSE people who had reactions on airplanes. That would really show us some concrete information. So if there are any researchers out there looking for a good topic... have I got an idea for you!
Please understand, I’m not trivializing the risks of food allergies on
airplanes. The risk is DEFINITELY still there. Here is a story of a woman who is severely allergic to peanut allergy who reacts to airborne particles (which may be more severe than some allergic individuals), and her bad reaction on a recent United flight: "
Peanut Allergy Causes Emergency Landing, Airline Sued,"
USAToday.com. As we plan our
vacations, we need to remember to be vigilant – take HandiWipes to wipe down
the seat tray, seat belt, and arm rests; notify the flight attendant of your
allergies (especially if you are traveling alone); keep your antihistamine and
epinephrine auto-injectors handy; and pack your own food or snacks for the
flight if at all possible.
By staying vigilant and being careful, we can reduce those
numbers of medical emergencies even more.
And, if the unthinkable happens and you DO suffer an
allergic reaction on the plane, there’s more good news. The FAA mandates that
every commercial airline keep an emergency medical kit onboard, and epinephrine
is a required medication in that kit. In addition, the study also showed that when
the flight attendants asked for medical help over the PA system, physicians
were on board 48% of the time, and professional nurses or emergency medical
technicians (EMTs) were on board another 25% of the time. So chances are very
good that there will be professional medical help on your flight should you
need it.
So if travel is in your future, plan ahead and stay
vigilant, but rest a little easier knowing that the odds appear to be good that you’ll have a
great time.
