Too Many Antibiotics Prescribed for Sore Throats?
Most ills are caused by viruses, end on their own, researchers report
By Steven Reinberg
THURSDAY, Oct. 3 (HealthDay News) -- Despite efforts to curb the unnecessary use of antibiotics, many doctors still prescribe them for illnesses that don't respond to the medications, Harvard researchers report.
Antibiotics only work against bacterial infections, and yet they are prescribed at a rate of 60 percent for sore throats and 73 percent for bronchitis, conditions that are typically caused by viruses, the scientists said.
"For sore throat, antibiotics should be prescribed about 10 percent of the time," said study author Dr. Jeffrey Linder, a researcher in the division of general medicine and primary care at Brigham and Women's Hospital in Boston.
Although the U.S. Centers for Disease Control and Prevention encourages the proper use of antibiotics, their use for sore throats has only dropped from about 70 percent of doctor visits in 1990 to 60 percent of visits now, he said.
"The story for bronchitis is even more bleak," Linder said. "The antibiotic prescribing rate was 73 percent and the right prescribing rate for bronchitis, according to guidelines, is zero," he said. "That hasn't changed at all over the last 30 years."
Linder thinks these rates remain high because, on the one hand, patients demand antibiotics from their doctors and, on the other hand, doctors don't want to miss a more serious condition such as pneumonia or strep throat.
"There's plenty of blame to go around," he said. "It's a lot easier to write a prescription than to have a five-minute conversation about why antibiotics aren't necessary.
"We need to have more faith in our bodies to get better from what are self-limiting conditions," he added. "The vast majority of sore throats, and virtually all of bronchitis [cases], get better on its own."
The report on sore throats was published online Oct. 3 in JAMA Internal Medicine, and the results of the bronchitis study are scheduled for presentation Thursday at ID Week 2013 in San Francisco.
Research presented at medical meetings is typically considered preliminary until published in a peer-reviewed journal.
Dr. Marc Siegel, an associate professor of medicine at the NYU Langone Medical Center in New York City, said, "This isn't new -- we are not listening."
