Abstract

Background:

Improving antibiotic use has the potential to decrease healthcare costs by reducing the incidence of antibiotic-resistant infections, antibiotic-associated adverse events, and expenditures due to unnecessary prescriptions. Antibiotic expenditures in 2009 totaled $10.7 billion in the United States. Since then, national and local antibiotic stewardship initiatives have grown. The purpose of this study was to assess trends in antibiotic expenditures by healthcare setting in the United States between 2010 and 2015.

Methods:

Systemic (nontopical) antibiotic expenditures from January 2010 to December 2015 were extracted from the QuintilesIMS National Sales Perspectives database. These data represent a statistically valid projection of US medication purchases. Regression analyses evaluated trends in expenditures over the study period.

Results:

Antibiotic expenditures totaled $56.0 billion over the 6-year period; the majority (59.1%) of expenditures were associated with the outpatient setting. Overall antibiotic expenditures in 2015 ($8.8 billion) were 16.6% lower than in 2010 ($10.6 billion). Antibiotic expenditures similarly decreased in the community by 25.5% (P = .05), but outpatient clinics and mail service pharmacy expenditures experienced significant growth (148% and 67% increase, respectively; P < .01 for both). In 2015, 16.5% of antibiotic expenditures in the community were for parenteral formulations, an increase of 25%.

Conclusions:

From 2010 to 2015, antibiotic expenditures decreased. The majority of antibiotic expenditures were in the outpatient setting, specifically community pharmacies. Expenditures for intravenous agents in the community are increasing and may represent increased use. These results reinforce the importance of antibiotic stewardship efforts across the spectrum of healthcare.
