A multi-hospital prevalence study of hospital-acquired infections (HAIs) was carried out between 19 March and 6 April 2007 in Liguria, Italy, being the first to be performed in this region. Of the 29 existing public acute hospitals, 25 took part in the investigation (86.2%). In total, 3176 patients were enrolled in the study, representing a regional average bed-occupancy rate of nearly 70%. Three-hundred and ten HAIs were diagnosed from 283 patients, with an overall prevalence of infections and cases of 9.8% and 8.9%, respectively. Prevalence varied considerably between hospitals, ranging from 0 to 24.4% [95% confidence interval (CI): 15.53-33.27]. Urinary tract infections (UTIs) (30.0%) and respiratory tract infections (RTIs) (26.1%) presented the highest relative frequency, followed by bloodstream infections (BSIs) (14.8%), surgical site infections (11.6%) and gastrointestinal infections (6.5%). Intensive care units (ICUs) and haemato-oncological units showed the highest specific prevalence of HAI, respectively 42.5% (95% CI: 34.48-50.52) and 13.3% (6.28-20.32), with RTI and BSI as the predominant infections. Spinal units (33.3%; 13.14-53.46) and functional-rehabilitation units (18.9%; 17.75-24.06) demonstrated a high rate of urinary tract infections. Uni- and multivariate analyses were performed to assess the main risk factors and conditions associated with HAI, both overall and by site. Our study provides an overall picture of the epidemiology of HAI in Liguria, which may be usefully employed as a starting point to plan and organise future surveillance and control programmes.
