Prevalence of healthcare-related infections in an intensive care unit of a teaching hospital in western Paraná

Resumo

Introduction:  Health Care-Related Infection (HAI) is a worrisome event for global public health, due to its high level of morbidity and mortality. Objective: To identify the main bacteria that cause infection in an Intensive Care Unit (ICU) and their sensitivity profiles. Methodology: Retrospective observational cross-sectional study, conducted in patients admitted to the ICU of a Teaching Hospital in the city of Cascavel - PR, in 2021. Results: Most patients were male (70.96%) and the microorganisms were isolated mainly from tracheal secretion (49.46%). Of the total of 186 patients admitted to the ICU, 120 (64.51%) had co-infection with SARS-CoV-2, and of these, 78 (42.29%) died. Of the total of 22 species of bacteria isolated, there was a higher prevalence of Pseudomonas aeruginosa (20.22%), followed by Klebsiella pneumoniae (15.73%) and Staphylococcus aureus  (9.55%). Regarding antimicrobial  resistance, Pseudomonas aeruginosa presented an average of 65.37% resistance to the drugs tested, followed by Klebsiella pneumoniae (58.45%) and Staphylococcus aureus (37.05%). Conclusion:  Pseudomonas aeruginosa was the main isolated bacterium, presenting high resistance to the drugs of the classes of quinolones, penicillins, cephalosporins, nitrofurans and sulfonamides, reaching up to 100% resistance to some antimicrobials tested.
