An increase of surgical site infections (SSIs) stemming from pathogens resistant to antibiotic prophylaxis could result in thousands of infection-related deaths in surgical and chemotherapy patients, according to a new study published in the Lancet Infectious Diseases.
A total of 31 published meta-analyses of randomized or quasi–randomized controlled trials were included in the study by Dr. Ramanan Laxminarayan of the Center for Disease Dynamics, Economics & Policy in Washington, and his associates. The researchers surveyed the 10 most common surgeries in which antibiotic prophylaxis provides the greatest benefit. The infection rate in surgical patients receiving prophylaxis was 4.2%, and was 11.1% in patients who did not receive prophylaxis. Relative risk reduction for infection was least in cancer chemotherapy at 35% and greatest in pacemaker implantation at 86%.
Between 38.7% and 50.9% of SSIs and 26.8% of infections after chemotherapy are caused by antibiotic-resistant pathogens. A decrease in prophylaxis effectiveness of 10% would cause 40,000 additional infections and 2,100 additional deaths, while a decrease in effectiveness of 70% would cause 280,000 additional infections and 15,000 additional deaths.
The authors say more data are needed to establish how antibiotic prophylaxis recommendations should be modified in the context of increasing rates of resistance.
In a related comment, Dr. Joshua Wolf from St. Jude Children’s Research Hospital, Memphis, said, “To improve stewardship outcomes, we need more research that focuses on understanding impediments to appropriate antibiotic prescribing, strategies that target these impediments, resources to implement the strategies, and leadership that understands the urgency and complexity of the task. In view of the lack of progress so far, mandatory implementation of these steps could be necessary to achieve notable change.”
