title: [Hospital infection surveillance in 5 Roman intensive care units].
abstract: The A.A. carried out a survey on hospital acquired infection (HAI) in the intensive care units (ICU) of five roman hospitals. The study monitored the following site-specific infection rates: pneumonia (PNE), blood stream infections (BSI), urinary tract infections (UTI), 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. The overall 503 patients characteristics (i.e., age, length of stay, case-mix...) showed the wards as general ICU's. Although the SAPS II score was similar, mortality (18.2%-42.9%) and general infection rates (15.4%-40.4%) among the five ICU's were considerably variable (p < 0.05), as HAI episodes distribution by type: PNE (37-88%), BSI (6-42%), UTI (6-24%), SSI (3-7%) (p < 0.05). Also device-associated infection rates such as Ventilator-associated PNE (11.6-24.6@1000), Vascular catheter-associated BSI (3.4-19.2@1000). Urinary catheter-associated UTI (2.6-14.0@1000) and invasive procedures management were different. Among the infected patients the most commonly isolated microorganisms were P. aeruginosa and Staphylococcus spp., which presented a considerable antibiotic resistance. The study showed: 1) sampling (i.e. blood cultures, tracheal aspirate and urine samples) and laboratory methodology indispensable for a correct HAI diagnosis were not standardized in the five ICU's; 2) hospital infection control policy was not carried out in all ICU's. The study showed a lack of standardization which limits the comparability of the general roman ICU's.
