This study aimed to analyze the main risk factors and prevalence of microorganisms from patients admitted in adult and neonatal ICUs. This was a retrospective study using data of microbial cultures and their respective patients admitted in adult and neonatal ICUs of a university hospital from the central region of Rio Grande do Sul, Brazil. In the adult ICU, 58.8% of patients presented heart problems, and 60 positive cultures were found with the prevalence of coagulase negative Staphylococcus (CNS) (30.0%) and Staphylococcus aureus (13.3%). In the neonatal ICU, patients predominantly presented pulmonary diseases (52.6%), and 31 positive cultures were found with the prevalence of CNS (35.5%) and Enterococcus spp. (16.1%). Thus, we conclude that both units surveyed had patients with different risk factors but with infections caused by Gram positive cocci, mainly CNS.
