Abstract
BACKGROUND: Catheter-related bloodstream infection (CR-BSI) remains a leading cause of nososcomial infection, despite the fact that many CR-BSIs are preventable. Simple principles of infection control and the use of novel devices to reduce these infections are not uniformly implemented. OBJECTIVE: To review and summarize the evidence that promotes strategies to prevent CR-BSIs. DATA SOURCES: The Medline database and bibliographies of review articles and book chapters were searched for relevant articles. STUDIES INCLUDED: In vitro and in vivo laboratory-based studies, controlled clinical trials, prospective interventional trials, and epidemiologic investigations. OUTCOME MEASURES: Reduction in CR-BSI, catheter colonization, tunnel infection, or local site infection. SYNTHESIS: The recommended prevention strategies with strong supportive evidence include educating and training of health care providers who insert and maintain catheters; using full barrier precautions during central venous catheter insertion; using a 2% chlorhexidine preparation for skin antisepsis; eliminating the practice of scheduled replacement of central venous catheters for prevention of infection; and using antiseptic/antibiotic impregnated short-term central venous catheters. CONCLUSION: Simple interventions can reduce the risk for serious catheter-related infection. Health care provider awareness and adherence to these prevention strategies is critical to reducing the risk for CR-BSI, improving patient safety, and promoting quality health care.
