OBJECTIVE: The COVID-19 pandemic has caused a global health crisis and may have affected healthcare-associated infections (HAI) prevention strategies. This study aims to evaluate the impact of the COVID-19 pandemic on HAI incidence in Brazilian ICUs. METHODS: This ecological study compared adult patients admitted to the ICU from April through June 2020 (pandemic period) with the same period in 2019 (pre-pandemic period) in 21 Brazilian hospitals. The difference in microbiologically confirmed central line-associated bloodstream infection (CLABSI) and ventilator-associated pneumonia (VAP) incidence density (cases per 1,000 patient days), the proportion of organisms that caused HAI, and antibiotic consumption (DDD) between the pandemic and the pre pandemic periods were compared in a pairwise analysis using the Wilcoxon signed rank sum test. RESULTS: We observed a significant increase in median CLABSI incidence during the pandemic (1.60 [0.44-4.20] vs. 2.81 [1.35-6.89], p = 0.002). There was no difference in VAP incidence between the two periods. In addition, there was a significant increase in the proportion of CLABSI caused by Enterococcus faecalis and Candida species during the pandemic, although only the latter retained statistical significance after correction for multiple comparisons. There was no significant change in ceftriaxone, piperacillin/tazobactam, meropenem, or vancomycin consumption between the studied periods. CONCLUSIONS: There was an increase in CLABSI incidence in Brazilian ICUs during the first months of COVID-19 pandemic. Additionally, we observed an increase in the proportion of CLABSI caused by E. faecalis and Candida species in this period. CLABSI prevention strategies must be reinforced in ICUs during the COVID-19 pandemic.
