Abstract
BACKGROUND: Healthcare-associated infection (HAI) represents a major problem for patient safety worldwide. AIM: To provide an up-to-date picture of the extent, aetiology, risk factors and patterns of infections in intensive care units (ICUs) in 28 Brazilian hospitals of different sizes. METHODS: A one-day point prevalence survey in 2016 enrolled the ICUs of hospitals from the 12 meso-regions in Minas Gerais state, south-east Brazil. Hospitals were classified as university or non-university hospitals. All patients with >48 h of admission to the study ICUs at the time of the survey were included. FINDINGS: In total, 303 patients were studied; of these, 155 (51.2%) were infected and 123 (79.4%) had at least one ICU-acquired infection. The most common ICU-acquired infections were pneumonia (53.0%) and bloodstream infection (27.6%). One hundred and nineteen bacterial isolates were cultured; the most common were Acinetobacter baumannii (27.1%), Pseudomonas aeruginosa (27.1%) and Staphylococcus aureus (39.0%). According to type of infection, the most common pathogens were P. aeruginosa (30.4%) in pneumonia, coagulase-negative staphylococci (23.4%) and Enterobacteriaceae (23.4%) in bloodstream infections, and Enterobacteriaceae (47.6%) in urinary tract infections. CONCLUSION: This study found that the overall prevalence of ICU-acquired infections in surveyed Brazilian hospitals was higher than that reported in most European countries and the USA. A greater proportion of infections were caused by non-fermenting Gram-negative bacteria. These observations, along with a high rate of antimicrobial use, illustrate the urgent need for HAIs to be a priority in the public health agenda of Brazil.
