How to deal with a child’s earache

Many doctors take the easy way out, prescribing antibiotics to wailing toddlers, but watchful waiting and pain relievers might be enough

Last March, while on vacation in Florida, my 11-month-old came down with a fever. We took him to a local paediatrician who quickly diagnosed him with a middle-ear infection and prescribed him a ten-day course of antibiotics. Two days later, back home in New York, our paediatrician said our son probably never had an ear infection, and that regardless, he should stop taking the drugs.

At the time, I was exceptionally annoyed. What irked me wasn’t just the misdiagnosis; it was that he had recommended unnecessary drugs that may have upset my baby’s stomach and potentially, research suggests, increased his risk for asthma and irritable bowel disease.

But it turns out Dr Florida’s actions were less the exception than the rule: Many paediatricians in the United States overdiagnose and overtreat ear infections, in part because of how difficult it is to accurately perform ear exams and in part because doctors feel you breathing down their stethoscope-adorned necks for the meds.

To make things even more complicated, the microbes that cause ear infections are changing: Vaccines have shifted the microbial flora blooming in American children, and thanks in part to routine antibiotic overuse, some bugs have become much harder to treat. Common in the wintertime, middle-ear infections — technically called acute otitis media, not to be confused with outer-ear infections (swimmer’s ear) or rare inner-ear infections — aren’t a big deal.

Nearly 80 per cent of American children have had one by the time they turn 3; many seem to battle them constantly — perhaps yours? No one knows why some children are more prone to them than others, but some research suggests that genetics plays a role, and environmental factors such as day care, exposure to tobacco smoke and formula feeding are known to boost the risk as well.

Ear infections can, however, be more than just a painful, oozing nuisance: They sometimes cause fluid to build up in the middle ear, leading to long-term hearing loss and language and literacy problems, and maybe even picky eating. Serious infections, left untreated, can also cause meningitis or mastoiditis, an infection of the mastoid bone in the skull, which requires surgery.

So, no, ear infections should not just be ignored. But a 2008 French study reported that one fifth of ear infections diagnosed by general practitioners are in reality something else, such as minor ear inflammation; 7 per cent of the time, doctors deem perfectly healthy ears infected. Why is ear health such a medical mystery?

Fevers, ear pulling and ear pain don’t necessarily predict the presence of an infection, so doctors have to examine the middle ear to be sure — and that is really hard to do to a sick child. Doctors typically have to insert an instrument into the kid’s ear, establish an airtight seal, squeeze a rubber bulb to release several bursts of air, and then watch to see how the child’s eardrum responds.

Oh, and if there is any earwax, the doctor has to pluck it out with tweezers and try the whole thing again. As you can imagine, this doesn’t always go well, so many paediatricians end up just peering into your child’s ear, seeing a little redness and guessing at a diagnosis instead.

Even if a doctor is certain of an infection, there is the problem of knowing what kind of ear infection it is. Some are caused by viruses, which are immune to antibiotics, whereas others arise because a respiratory virus such as the cold or flu made it easier for pre-existing bacteria to grow in the middle ear canal.

The only way a doctor can tell an infection’s microbial origin is by inserting a needle into a child’s eardrum and aspirating out some of the middle ear fluid, which thankfully few doctors do. Problem is, without knowing what is causing an infection, it is difficult to know how best to treat it.

Since 2004, the American Academy of Paediatrics has advised doctors against giving antibiotics to children over the age of 2 if their ear infections are not severe. (All children under 6 months should get antibiotics, and children between 6 months and 2 years should get them only if the doctor is absolutely certain of the infection, which is apparently only half the time.)

Under this “watchful waiting” approach, doctors are supposed to re-examine the child a few days later to see if the infection is getting better; if it is not, drugs then might be in order. There is a good reason for this conservative approach: No matter what their cause, most ear infections go away on their own.

In a 2011 clinical trial, University of Pittsburgh researchers reported that 74 per cent of children under the age of 2 who were suffering from ear infections got better after one week when they weren’t given any treatment; 80 per cent of those who got antibiotics got better in the same time frame.

Yet half of the children treated with antibiotics in the study got bouts of diarrhoea, compared with only 27 per cent of the children who didn’t take anything. So, yes, after a week on amoxicillin your son finally stopped wailing, waking in the night, and tugging at his ear. But that could very well have been just because time had passed and his immune system fought the bug off.

The bottom line is that ear infections are beguiling, yet they are also less common than you might have been led to believe and more innocuous as well. This doesn’t mean you shouldn’t take your shrieking, ear-clawing child to the paediatrician. You should. But don’t pitch a fit while you are there — what do you mean you are not giving Lola antibiotics?

She has been screaming for 17 hours! — and if your doctor prescribes drugs without skipping a beat, consider asking if a watchful waiting approach might work instead. Then, pick up some pain relievers on the way home.
