Abstract

PURPOSE
This study was to examine whether VRE infection control strategies have an effect on the decrease in incidence rates for VRE acquisition and VRE nosocomial infection in ICU.
METHODS
All the patients were examined for VRE carriers on ICU admission. Among them, patients hospitalized for over 48 hours were investigated for VRE acquisition rates and VRE nosocomial infection rate using VRE infection control strategies in ICU for the experimental group from September 2007 to April 2008. Before that, incidence of VRE acquisition and VRE nosocomial infection for the control group without Intervention were investigated from May to August 2007 retrospectively.
RESULTS
VRE acquisition rate in clinical specimens was 0.6% in the experimental group, that was significantly lower when compared to the control group. VRE carrier rate at admission to ICU was 15.4%. Out of 182 VRE carriers, 180 patients were identified by the active surveillance culture.
CONCLUSION
These results suggested that active surveillance culture at admission was considered to be an essential measure for detection of VRE carrier. But without strict isolation and adherence rating after each intervention, hand washing and contact isolation alone did not significantly decrease VRE nosocomial infection, although it did significantly decrease incidence of VRE acquired from clinical specimen.
