You're Probably Treating Your Pinkeye Wrong, Study Says
If you have pinkeye and a health care provider prescribes you an antibiotic eyedrop, that might not be the correct treatment after all.
That's according to a new study
out of the University of Michigan, which found that approximately 60
percent of patients across the country receive such prescriptions
despite the fact they aren't typically necessary for treatment. What's
more: 20 percent of those who filled these prescriptions got
antibiotic-steroid eyedrops that could make the infection worse or last
longer.
The results are in line with a trend across the country
of antibiotic misuse when it comes to treating common viral and mild
bacterial illnesses. The study was published in Ophthalmology, the journal of the American Academy of Ophthalmology.
There are three types of pinkeye: viral, bacterial and
allergic conjunctivitis. Antibiotics can't fix viral infections or
allergies, where most of the cases originate.
The data for the study came from a large managed care
network in the United States. Researchers found that of the 340,372
people who received an acute conjunctivitis (pinkeye) diagnosis across a
14-year span, 58 percent filled their antibiotic eyedrop prescription.
Only a small amount of these people received a diagnosis from an
ophthalmologist, with the others seeing the likes of a family medicine
physician, pediatrician and others.
"Filling antibiotic prescriptions seems to be driven more
by sociodemographic factors and type of provider diagnosing the
enrollee than by medical indication," according to the study.
For instance, those who wear contact lenses or who had diabetes or HIV/AIDS have a higher risk for such an infection.
In addition, there was a two or three times higher likelihood that people would fill antibiotic eyedrop prescriptions if a primary care or urgent care provider gave the diagnosis compared to an ophthalmologist.
Why are they overprescribed? Authors point to school
policies (i.e. kids not being allowed in school without treatment) and a
lack of education among patients as reasons, not to mention that much
about the causes are still unknown. Health care providers could also be
prescribing antibiotics unnecessarily.
"Educating patients about acute conjunctivitis' often
benign, self-limited course may help to dispel misconceptions about the
condition and reduce reflexive demands for immediate antibiotic use,"
Dr. Joshua Stein, study author, said in a statement.
In the United States alone, 6 million people get pinkeye every year.
