Trends in surgical site infections following orthopaedic surgeryLamagni, Theresa; Elgohari, Suzanne; Harrington, PaulineCurrent Opinion in Infectious Diseases: April 2015 - Volume 28 - Issue 2 - p 125–132 doi: 10.1097/QCO.0000000000000143 SKIN AND SOFT TISSUE INFECTIONS: Edited by Matthew S. Dryden Abstract Author Information Purpose of review This review presents an update on recent findings relating to the prevention, control and epidemiology of infections following orthopaedic surgery. Recent findings Trends in population rates and characteristics of patients undergoing hip and knee replacement surgery, coupled with the reported excess infection risk in obese patients, emphasize the current and future impact of increasing population obesity on healthcare delivery. Summary Prevention of orthopaedic infection is dependent on elimination or optimal management of documented risk factors. Guidelines and quality standards play a key role in translating this evidence base into a framework of practices for the prevention of surgical site infections. Increasing levels of orthopaedic infection due to Enterobacteriaceae, coupled with an increasingly obese surgical population may necessitate a reassessment of antimicrobial prophylaxis strategies.
