[NEOCAT, surveillance network of catheter-related bloodstream infections in neonates: 2010 data]

Abstract

The NEOCAT surveillance network was implemented in 2006 in order to address catheter-associated bloodstream infections (BSIs) in neonates. The results for 2010 surveillance are presented herein. Neonatal intensive care units (NICUs) participated in the study on a voluntary basis. Umbilical catheters (UCs) and central venous catheters (CVCs) were analyzed separately. In 2010, 26NICUs participated. Overall, 2953 neonates were included (median weight, 1550 g; median gestational age, 32 weeks). These neonates had 2551UCs (median insertion duration, 4 days) and 2147CVCs (median insertion duration, 12 days). Thirty-three BSIs associated with UCs were reported, yielding a 2.9/1000UC-day incidence density, 95% confidence interval (95%CI) (1.9-3.8). UC-associated BSIs appeared after a median period of 5 days after UC insertion. The main microorganism isolated from blood cultures was coagulase negative staphylococci (CNS, n=27), S. aureus (n=3), and Enterobacteriaceae (n=5). Three hundred and six CVC-associated BSIs were recorded, yielding a 11.2/1000 CVC-day incidence density (95%CI, 10.0-12.5). These BSIs occurred after a median period of 12 days after CVC insertion. The main microorganisms were CNS (83%), S. aureus (6%), and Enterobacteriaceae (5%). The NEOCAT network provides a useful benchmark for participating wards.
