Significant Reduction of Catheter-associated Blood Stream Infections in Preterm Neonates After Implementation of a Care Bundle Focusing on Simulation Training of Central Line Insertion.

Abstract

Central line-associated blood stream infections (CLABSIs) are common problems in neonatal intensive care units (NICUs). Implementation of catheter care bundles has been shown to reduce CLABSI rates. We developed a care bundle aiming at establishing a uniform central line insertion technique and improving teaching practices focusing on simulation-based techniques. The purpose of this study was to assess the impact of this care bundle on CLABSI rates in very low birth weight infants (VLBWI). In September 2010, a CLABSI prevention bundle was introduced in our NICU, consisting of simulation-based standardization and education of a peripherally inserted central catheter insertion technique. Data of all VLBWI admitted to our NICU during 2010-2012 were analyzed. Diagnosis of CLABSI required a positive blood culture in the presence of a central venous catheter and clinical signs of infection. Five hundred twenty-six VLBWI admitted during the study period were included into the analysis. CLABSI rates decreased significantly from 13.9 in 2010 to 9.5 in 2011 and 4.7 in 2012 (P < 0.0001). This significant reduction was true for the overall population and for subgroups separated by birth weight. Distribution of blood culture pathogens revealed a constant absolute and relative decline of infections with coagulase-negative staphylococci from 2010 (n = 43/50, 86%) to 2012 (n = 12/18, 67%), as opposed by a slight increase of Staphylococcus aureus infections (n = 1/50, 2% in 2010 versus n = 2/18, 11% in 2012). Our data provide evidence of a potential effect of simulation-based training of central line placement in decreasing CLABSI rates in VLBWI and encourage its implementation into care bundles.
