New research suggests a pattern of outpatient antibiotic overuse in parts of the United States - particularly in the Southeast - a problem that could accelerate the rate at which these powerful drugs are rendered useless, according to Extending the Cure, a project of the Center for Disease Dynamics, Economics & Policy.
These findings come out just as the Centers for Disease Control and Prevention (CDC) kicked off an annual effort to reduce overuse of antibiotics called "Get Smart: Know When Antibiotics Work." The campaign, which lasts throughout the week, urges Americans to use antibiotics wisely. The CDC estimates that $1.1 billion is spent annually on unnecessary antibiotic prescriptions for adult upper respiratory infections alone. These prescriptions also speed the development of resistance to important antibiotic therapies.
Also, Extending the Cure introduced a new tool that allows non-experts to track changes in antibiotic effectiveness over time. The new Drug Resistance Index (DRI) is similar in concept to the Consumer Price Index and is described in a paper in the British Medical Journal Open.
