Tunneled, cuffed, double-lumen catheters are commonly used for long-term venous access in hemodialysis patients. Complications of these catheters, including catheter-related infection, are a major cause of morbidity and resource utilization in the hemodialysis population. Treatment of catheter-related bloodstream infections includes the use of antibiotics and evaluation of the need for catheter removal or exchange. Measures to prevent catheter-related infections include use of an aseptic technique and antiseptic cleaning solution, elimination of Staphylococcus aureus nasal carriage, topical exit site application of antibiotics, use of antibiotic lock solutions, and use of catheters and cuffs coated or impregnated with antimicrobial or antiseptic agents. This review article will provide an update on the prevalence, diagnosis, treatment, and prevention of catheter-related infections in the hemodialysis population.
