Outpatient Antibiotic Use in the United States

This data visualization was updated on October 19, 2017 with outpatient antibiotic prescribing data from 2015.

The use of antibiotics is an important factor in the development of antibiotic resistance. Prescriptions written for these drugs in outpatient health care settings—such as doctor’s offices and emergency rooms—account for a significant proportion of total antibiotic use in health care settings across the United States. To improve judicious antibiotic use in these facilities, it is important to understand how these drugs are prescribed. Presented below are results of an analysis of outpatient antibiotic prescribing practices in the United States in 2015 using IMS Health Xponent data.1
