RESUMO
BACKGROUND: Healthcare Associated Infections (HAI) are the most serious complication associated with health care. They cause diseases for patients and economic damage for Public Health. A prevalence survey at the University Hospital "Federico II" of Naples was conducted according to ECDC criteria in order to analyze the infectious phenomenon of healthcare assistance and assess possible correlations with risk factors as healthcare procedure and clinical condition of patients. METHODS: Were enrolled 450 patients. The collected data were then analyzed using univariate and multivariable logistic regression. RESULTS: It was found a prevalence rate of infections of 9.3%, with a prevalence rate of HAI of 4.4%. Statistical analysis showed correlation between HAI and ultimately-fatal-disease (P <0.04) and between HAI and the use of invasive devices as CVC (P<0.005), PVC (P<0.004) and intubation (P<0.01). CONCLUSIONS: The epidemiological surveillance strategies are part of preventive measures and monitoring of the HAI, implemented to ensure safety and quality of care.
