High rates of inappropriate antibiotic use continued despite a 15-year campaign by the Centers for Disease Control and Prevention (CDC) aimed at Michigan physicians and consumers on the dangers of antibiotic overuse.
The Center for Healthcare Research & Transformation (CHRT) released an issue brief detailing overall antibiotic prescribing for adult Blue Cross Blue Shield of Michigan (BCBSM) members. (The project is a non-profit partnership between the University of Michigan and BCBSM.)
While antibiotic prescribing in adults decreased 9.3 percent from 2007 to 2009, it increased 4.5 percent for children during the same time period. The studies found significant differences in prescribing patterns between rural southeast Michigan and the rest of the state, particularly for children. Children in rural southeastern Michigan were prescribed an average of .93 antibiotics per year, while elsewhere children were prescribed an average of 1.0 per year.
“The continuing high rate of antibiotic use for viral infections in children and adults — particularly outside of southeast Michigan — is of great concern, as is the increase in the use of broad spectrum antibiotics in children,” said Marianne Udow-Phillips, CHRT’s director. “Using antibiotics when they are unnecessary — or treating simple infections with drugs that should be reserved for the most serious infections — are practices that contribute to antibiotic resistance, making future infections harder to treat.”
Nearly half (49.1 percent) of antibiotic prescriptions in the study population were for broad spectrum antibiotics in 2009, compared to the national rate of 47 percent. Between 2007 and 2009, prescriptions for what the National Committee for Quality Assurance calls “antibiotics of concern” declined slightly in adults, decreasing 0.4 percent during that time period. In the same time period, antibiotics of concern prescribed to children increased 3.4 percent, from 44.9 percent to 46.4 percent.
One possible explanation for the rising rate in children is a rise in resistant pathogens in ear infections, according to the study brief. Other possible reasons are that kids get different infections than adults, and that some drugs that are used in adults are not used for pediatric patients. Read more »
