Central venous catheter-related blood stream infection rate in critical care units in a tertiary care, teaching hospital in Mumbai

Blood stream infections related to central venous catheterization are one of the major device-associated infections reported. Patients admitted in critical care units requiring central venous catheterization and presenting with signs of septicemia during catheterization period were investigated for catheter-related blood stream infections (CRBSI). The CRBSI rate was 9.26 per 1000 catheter days in general with highest rate in neonatal intensive care unit (27.02/1000 days). Site of insertion of catheter and duration of catheterization did not show the influence on the CRBSI rate. Coagulase-negative Staphylococci were the predominant cause. Mortality of 33% was observed in patients with CRBSI. Since central venous catheters are increasingly being used in the critical care, regular surveillance for infection associated them are essential.
