- Impact of Discontinuing Levofloxacin Prophylaxis on Bloodstream Infections in Neutropenic Hematopoietic Stem Cell Transplantation Patients(2022) GUIMARAES, Thais; BORGES, Igor Carmo; SPADAO, Fernanda de Souza; MARIANO, Livia; NASCIMENTO, Marina de Mattos; HIGASHINO, Hermes; ROSSI, Flavia; ROCHA, Vanderson; COSTA, Silvia FigueiredoMultidrug-resistant pathogens have emerged worldwide. We have driven the hypothesis that the non-use of fluoroquinolone prophylaxis during neutropenia could reduce antibiotic resistance in Gram-negative bacteria that cause bloodstream infections (BSIs) in hematopoietic stem cell transplantation (HSCT) patients and that this change in resistance pattern could lead to an impact on BSI mortality. This is a quasi-experimental study comparing BSI incidence, resistance patterns of bacteria that cause BSI, and BSI mortality when levofloxacin prophylaxis was routine for neutropenic HSCT patients (2016-2018) to when fluoroquinolone prophylaxis was discontinued in our center (2019). Bivariate comparisons and multivariate logistic regression models were used for analyses. A total of 310 HSCTs (66 (21%) allogeneic and 244 (79%) autologous) were performed during the study period. Sixty (19%) patients had BSIs, 30 in each evaluated period. The discontinuation of levofloxacin prophylaxis was associated with an increase in BSI incidence and a decrease in the resistance rates of causative BSI bacteria and in BSI 30-day mortality. The increase in the rate of resistant bacteria causing BSI and in BSI mortality might outweigh the benefits of a decrease in BSI incidence caused by fluoroquinolone prophylaxis in neutropenic HSCT patients. We suggest that the routine use of fluoroquinolone in this context be revisited.
- Risk factors for reduction in adherence to protective measures following coronavirus disease 2019 (COVID-19) vaccination and vaccine perceptions among healthcare workers, in Sao Paulo, Brazil(2023) LOPEZ, Andres Mello; BORGES, Igor Carmo; LUNA-MUSCHI, Alessandra; PERES, Carlos Henrique Mesquita; CARRENO, Paolo Gripp; OLIVEIRA, Arthur Magalhaes de; ALMEIDA, Humberto Bertola Siqueira de; MARQUES, Vivian Helena de Castro; CORCHS, Felipe; LEVIN, Anna Sara; COSTA, Silvia Figueiredo; SARTORI, Ana Marli ChristovamA survey evaluated 2,300 healthcare workers following the first dose of a coronavirus disease 2019 (COVID-19) vaccine in a tertiary-quaternary hospital in Sao Paulo, Brazil. Adherence to protective measures following vaccination was compared to previous non-work-related behaviors. Younger age, previous COVID-19, and burnout symptoms were associated with reduced adherence to mitigation measures.
- Healthcare-associated infections on the intensive care unit in 21 Brazilian hospitals during the early months of the coronavirus disease 2019 (COVID-19) pandemic: An ecological study(2023) PORTO, Ana Paula M.; BORGES, Igor C.; BUSS, Lewis; MACHADO, Anna; BASSETTI, Bil R.; COCENTINO, Brunno; BICALHO, Camila S.; CARRILHO, Claudia; RODRIGUES, Cristhieni; NETO, Eudes A.

F.; COUTINHO, Rosane L.; GUIMARAES, Thais; FERRAZ, Tiago L. L.; LEVIN, Anna S.; COSTA, Silvia F.Objective: The coronavirus disease 2019 (COVID-19) pandemic has caused a global health crisis and may have affected healthcare-associated infection (HAI) prevention strategies. We evaluated the impact of the COVID-19 pandemic on HAI incidence in Brazilian intensive care units (ICUs). Methods: In this ecological study, we compared adult patients admitted to the ICU from April through June 2020 (pandemic period) with the same period in 2019 (prepandemic period) in 21 Brazilian hospitals. We used the Wilcoxon signed rank-sum test in a pairwise analysis to compare the following differences between the pandemic and the prepandemic periods: microbiologically confirmed central-line-associated bloodstream infection (CLABSI) and ventilator-associated pneumonia (VAP) incidence density (cases per 1,000 central line and ventilator days, respectively), the proportion of organisms that caused HAI, and antibiotic consumption (DDD). Results: We detected a significant increase in median CLABSI incidence during the pandemic: 1.60 (IQR, 0.44-4.20) vs 2.81 (IQR, 1.35-6.89) (P = .002). We did not detect a significant difference in VAP incidence between the 2 periods. In addition, we detected a significant increase in the proportion of CLABSI caused by Enterococcus faecalis and Candida spp during the pandemic, although only the latter retained statistical significance after correction for multiple comparisons. We did not detect a 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 detected an increase in the proportion of CLABSI caused by E. faecalis and Candida spp during this period. CLABSI prevention strategies must be reinforced in ICUs during the COVID-19 pandemic.
