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.
