Systemic oral antibiotics were extracted from the IMS Health Xponent database. IMS Health captures >70% of outpatient prescriptions nationally, reconciles them to wholesale deliveries, and projects to 100% coverage. These data represent all outpatient antibiotic prescriptions from community pharmacies and non-governmental mail order pharmacies from all payers, but exclude federal facilities. Provider specialties are taken from the American Medical Association (AMA) self-designated practice specialties and categorized into one of 17 groups. Population data were obtained from the U.S. Census bridging files.
