Abstract:
OBJECTIVETo assess the risk factors for nosocomial blood-stream infection (BSI) in a neonatal intensive care unit (NICU).
METHODSClinical data from the neonates admitted to the NICU in the St. Louis Children's Hospital in Washington University School of Medicine between January 2005 and December 2006 were retrospectively studied.
RESULTSA total of 1 290 neonates were included. Overall, 175 nosocomial BSIs occurred. Catheter-related BSIs accounted for 62.3% (109 cases). The incidence of nosocomial BSI was 4.22 per 1 000 patient-days. Logistic regression analysis revealed that low gestational age, low Apgar scores at 5 minutes, use of central venous catheter (CVC), and longer CVC use were risk factors for the development of nosocomial BSI. In the subgroup of neonates with CVC, mechanical ventilation was an additional independent risk factor for BSI.
CONCLUSIONSCatheter-related BSI is the major source of nosocomial BSI in the NICU. Prematurity, low Apgar scores at birth and prolonged CVC use are risk factors for the development of BSI.
