As part of an ongoing collaboration to improve stewardship of lifesaving antibiotics in the U.S., Pew and the Centers for Disease Control and Prevention (CDC) developed a new resource to help hospitals reduce the risk of antibiotic resistance and improve patient care. Created with input from leading antibiotic use experts, the standardized antibiotic administration ratio (SAAR) assessment tool will help health care providers interpret and use antibiotic prescribing data from the CDC’s National Healthcare Safety Network. Pew and CDC hope that hospitals will use this resource to evaluate the appropriateness of their antibiotic use and for targeting stewardship initiatives moving forward.
