Researchers at Intermountain Healthcare and University of Utah Health in Salt Lake City have completed a study identifying how community hospitals with fewer than 200 beds can develop antibiotic stewardship programs that work to prevent the growth of antibiotic-resistant organisms, or "superbugs," which are becoming more common and deadly.
For the 15 month-study, researchers compared the impact of three types of antibiotic stewardship programs in 15 small hospitals within the Intermountain Healthcare system. They found the most effective program used infectious disease physicians and pharmacists at a central hospital working with local pharmacists to reduce broad-spectrum antibiotic use by nearly 25 percent and total antibiotic use by 11 percent.
Researchers found other programs without central support did not see an improvement in antibiotic use. Results of the new study are published in the medical journal, Clinical Infectious Diseases.
All hospitals, no matter how large or small, need antibiotic stewardship programs to help physicians use antibiotics optimally and prevent the growth of antibiotic-resistant organisms. Until now, it's been unclear how small community and rural hospitals could build such programs to effectively reduce antibiotic use. Antibiotic stewardship programs are now required in all U.S. hospitals regardless of their size.
Antibiotic resistance, which is accelerated by the overuse of antibiotics, means bacteria adapt in a way that reduces or eliminates the ability of antibiotics to cure or prevent infections. The bacteria can then turn into drug-resistant "superbugs" that can cause life-threatening infections. Antibiotics are also responsible for many side effects in patients in the hospital, including Clostridium difficile, or C diff.
Hospitals across the country are required by The Joint Commission to implement antibiotic stewardship programs to improve antibiotic prescribing in hospitals, since experts estimate 30 to 50 percent of prescribed antibiotics could be used more effectively -- or are unnecessary.
"Having an antibiotic stewardship program in place that ensures the right antibiotic is used for the right patient, at the right time, in the right dose and route, and for the right duration will help us protect the effectiveness of the antibiotics we use," said Eddie Stenehjem, MD, an infectious disease specialist with Intermountain Medical Center and lead author of the study.
