Incidence Trends in Pathogen-Specific Central Line–Associated Bloodstream Infections in US Intensive Care Units, 1990–2010

Patterns of ICU CLABSI incidence density rates among major pathogen groups have changed considerably during recent decades. CLABSI incidence declined steeply since 2006, except for CLABSI due to S. aureus in pediatric ICUs. There is a need to better understand CLABSIs that still do occur, on the basis of microbiological and patient characteristics. New prevention approaches may be needed in addition to central line insertion and maintenance practices.
