Clinical question: How has inpatient antibiotic use changed in the United States in recent years?
Study design: Retrospective analysis.
Setting: Adult and pediatric data from 300 acute-care hospitals, 2006-2012.
Synopsis: Weighted extrapolation of data from a database was used to estimate national antibiotic use. Overall, 55.1% of discharged patients received antibiotics. The rate of antibiotic use was 755/1,000 patient-days over the study period. The small increase in antibiotic use over the years (5.6 days of therapy/1,000 patient-days increase; 95% CI, –18.9 to 30.1; P = .65) was not statistically significant. There was a significant decrease in the use of aminoglycosides, first- and second-generation cephalosporins, fluoroquinolones, sulfonamide, metronidazole, and penicillins. The use of third- and fourth-generation cephalosporins, macrolides, glycopeptides, beta-lactam/beta-lactamase inhibitor, carbapenems, and tetracyclines has increased significantly.
Limitations of the study include underrepresentation of pediatric hospitals and certain geographic regions.
Bottom line: Antibiotic-use rates have not changed during 2006-2012. However, broad-spectrum antibiotic use has increased significantly.
