A ten-year review of total hospital onset intensive care unit bloodstream infections at an Academic Medical Center

Objective

The rates of central line–associated bloodstream infections (CLABSIs) in United States intensive care units (ICU) have decreased significantly, and a parallel reduction in the rates of total hospital onset bacteremias in these units should also be expected. We report 10-year trends for total hospital onset ICU-associated bacteremias at a tertiary care academic medical center.

Design

This was a retrospective analysis of all positive blood cultures among patients admitted to seven adult ICUs for the period FY2005 through FY2014 according to Centers for Disease Control and Prevention National Healthcare Safety Network definitions. The rate of change for primary and secondary hospital onset BSIs was determined, as was the distribution of organisms responsible for these BSIs.

Setting

Three medical, two general surgical, one combined neurosurgical /trauma, and one cardiac/cardiac surgery adult intensive care units.

Results

Across all ICUs, the rates of primary BSIs progressively fell from 2.11/1000 patient days in FY05 to 0.32/1000 patient days in FY14; an 85.0% decrease (PConclusions
