The research was conducted by CDC and Premier, a performance improvement company. Researchers conducted a retrospective analysis of inpatient pharmacy data from more than 500 U.S. hospitals. The analysis showed that 78 percent of hospitals had evidence of potentially unnecessary antibiotic combinations being administered for two or more days, with a total of 32,507 cases of redundant antibiotics treatment.
The study found that these cases represented 148,589 days of potentially inappropriate antibiotic therapy, resulting in nearly $13 million in potentially avoidable healthcare costs from antimicrobial drugs. If these cases were representative of all U.S. hospitals over the same time period, an estimated $163 million could have been saved through appropriate prescribing.
“Improving the way antibiotics are prescribed not only helps reduce rates of Clostridium difficile infection and antibiotic resistance, but can also improve individual patient outcomes, all while reducing healthcare costs,” said Arjun Srinivasan, MD, associate director for Healthcare Associated Infection Prevention Programs in the Division of Healthcare Quality Promotion at CDC and a study author.
