Infection surveillance in ICU is fundamental for monitoring endemic rates, identifying outbreaks in time in order to activate control procedures and implement sound empirical antibiotic treatment. The data collection surveillance software CIN-2000 was established in the Umberto I ICU Teaching Hospital to monitor the following site-specific infection rates: urinary tract infections (UTI), pneumonia (PNE), blood stream infections (BSI), surgical site infections (SSI). According to CDC definitions all patients developing infection 48 hours or more after ward admission were included. Furthermore risk factors (i.e. age, sex, SAPS II), invasive procedures (i.e. endotracheal intubation, vascular and urinary catheterisation), microbiological isolates and their antibiotic susceptibility were screened. Overall 279 patients (183 men and 96 women) were admitted; age 54.8 ± 20.3 years (mean), SAPS II 44.4 ± 17.1 (mean) and average ward stay 13.3 ± 17.8 days. The results showed a total of 121 infection episodes (56 PNE, 51 BSI, 10 UTI e 4 SSI) in 80 patients (28.7%). Standardized infection rates associated to invasive procedures were: Urinary catheter-associated UTI rate (2.9/1000), Ventilator-associated PNE rate (20.4/1000), Vascular catheter-associated BSI rate (19.1/1000). Among the infected patients the most common micro-organisms isolated were P. aeruginosa (31.8%), MRSA (14.8%), A. baumannii (12.5%) and S. maltophilia (8.5%); considering site-specific infections: PNE (P. aeruginosa 38.3% and MRSA 18.1%), BSI (MR CNS 21.9% and P. aeruginosa 17.2%), UTI (P. aeruginosa 70.0%). The surveillance software CIN-2000 proved to be very accurate, useful and easy to use. The results showed a high incidence of infections associated to invasive procedures and the presence of multiresistant bacteria.
