Study Finds Wide Variations in Antibiotic Prescribing Among Elderly

Study results published in the Archives of Internal Medicine suggest there was wide variation in antibiotic prescribing for older patients based on geography and the season in which the prescriptions were written.

Researchers studied Medicare Part D data from 2007 to 2009 to examine geographic variation in antibiotic use among older adults. Results from that research show the highest antibiotic use was in the South (21.4 percent of patients per quarter used an antibiotic) and the lowest in the West (17.4 percent).

Researchers also found that, regardless of region, the antibiotic use was highest in the first quarter of the year and lowest in the third quarter.
