High Incidence of Subclavian Dialysis Catheter-Related Bacteremias

Abstract This retrospective cohort study reviews the incidence of bacteremia in 48 patients undergoing hemodialysis using subclavian vein dialysis catheters (SDC) as temporary vascular access. Twelve (25%) of these patients had catheter-related bacteremia, and the most frequently isolated organisms were coagulase-negative staphylococci. Three patients developed right-sided endocarditis and one of diem died due to pulmonary embolism. The presence of possible risk factors for SDC-related bacteremia, including duration of catheterization and number of hemodialysis procedures, were not statistically different when patients with and without bacteremia were compared, with the exception of a significantly lower incidence of bacteremia among those patients receiving antibiotic therapy at the time of catheter insertion. The use of resterilized catheters was not a risk factor. Specific guidelines for SDC insertion and care were established and followed, after which the infection frequency was reduced to 7.5% (1 episode per 45.5 patient-weeks of catheter use) in this high-risk population
