    Abstract:
    The intensive care unit (ICU) standardized protocol of the NNIS (National Nosocomial Infections Surveillance) system is a surveillance method of hospital acquired infections (HAI), which provides device-associated infection rates. The aim of this study was to assess the effectiveness and the required time for data collection and analysis of a selective surveillance method (SSM) derived from the NNIS ICU surveillance protocol, and to compare its data with that of a reference surveillance method (RSM). The sensitivity, specificity and the positive predictive value (PPV) of the RSM were 87.5, 100 and 100%, respectively. The sensitivity, specificity and the PPV of the SSM were 59.4 97.6 and 79.2%, respectively. Considering device-related infections only (ventilator-related pneumonia, catheter-related urinary tract infections, central line-related sepsis), the sensitivities of the RSM and the SSM were 80.9 and 90.5%, respectively. The SSM required only one third of the time of the RSM (1.1 h and 3.4 h per 10 beds per week with the SSM and the RSM, respectively). We conclude that the SSM has a very high sensitivity for detecting device associated infections, but is not sensitive enough for surveying all types of HAI.
