Medexter Healthcare put into operation its latest Moni/Surveillance-ICU software for identification and monitoring of hospital-acquired infections in adult patients at intensive care units (ICUs) of the Vienna General Hospital/Medical University of Vienna (AKH Wien/MUW). This software replaces the Moni-IV system that has been running since July 2007. Like its counterpart for neonatal ICUs, it accesses patient care data collected by the installed Philips CareVue intensive-care medical information systems at the connected 12 ICUs (96 beds). The software monitors the incoming routine data for signs of hospital-acquired blood stream infections, ICU-acquired pneumonias, urinary tract infections, and central venous catheter-related infections, and provides the infection control personnel of the Vienna General Hospital with the results. Technically, Moni/Surveillance-ICU is based on web-services made available in the AKH Wien-wide intranet, and on an extended knowledge base, implemented in form of Arden Syntax medical logic modules (MLMs), extended by fuzzy set and fuzzy logic methods. The cockpit surveillance application allows detailed case-specific interactive analyses of the detected results. The results are updated routinely every day, but may by renewed on request if an epidemic situation calls for close monitoring.
