ABSTRACT
BACKGROUND: Intravenous (IV) antibiotics have historically been considered standard of care for treatment of bloodstream infections (BSIs). Recent literature has shown sequential oral (PO) therapy to be noninferior to IV antibiotics for certain pathogens and disease states. However, a gap exists in the literature for BSI caused by Enterococcus faecalis. OBJECTIVE: To compare outcomes of definitive sequential PO therapy to definitive IV therapy in patients with E faecalis BSI. METHODS: Multicenter, retrospective, matched cohort study of adult patients with at least one blood culture positive for E faecalis from January 2017 to November 2022. Patients with polymicrobial BSI, concomitant infections requiring prolonged IV antibiotic therapy, those who did not receive antibiotic therapy, and those who died within 72 hours of index culture were excluded. Subjects were matched based on source of infection in a 2:1 (IV:PO) ratio. The primary outcome was a composite of all-cause mortality and treatment failure. Secondary outcomes included hospital length of stay (LOS), antibiotic duration, and 30-day readmission rate. RESULTS: Of the 186 patients who met criteria for inclusion, there was no statistically significant difference in the primary composite outcome for PO compared to IV therapy (14.5% vs 21.8%; OR 0.53 [0.23-1.25]) or 30-day readmission (17.5% vs 29%; OR 0.53 [0.25-1.13]). Hospital LOS was significantly longer in patients receiving IV-only therapy (6 days vs 14 days; P < 0.001). CONCLUSION AND RELEVANCE: Sequential oral therapy for E faecalis BSI had similar outcomes compared to IV-only treatment and may be considered in eligible patients.
ABSTRACT
Purpose: The medication regimen complexity-intensive care unit (MRC-ICU) score was developed prior to the existence of COVID-19. The purpose of this study was to assess if MRC-ICU could predict in-hospital mortality in patients with COVID-19. Methods: A single-center, observational study was conducted from August 2020 to January 2021. The primary outcome of this study was the area under the receiver operating characteristic (AUROC) for in-hospital mortality for the 48-hour MRC-ICU. Age, sequential organ failure assessment (SOFA), and World Health Organization (WHO) COVID-19 Severity Classification were assessed. Logistic regression was performed to predict in-hospital mortality as well as WHO Severity Classification at 7 days. Results: A total of 149 patients were included. The median SOFA score was 8 (IQR 5-11) and median MRC-ICU score at 48 hours was 15 (IQR 7-21). The in-hospital mortality rate was 36% (n = 54). The AUROC for MRC-ICU was 0.71 (95% Confidence Interval (CI), 0.62-0.78) compared to 0.66 for age, 0.81 SOFA, and 0.72 for the WHO Severity Classification. In univariate analysis, age, SOFA, MRC-ICU, and WHO Severity Classification all demonstrated significant association with in-hospital mortality, while SOFA, MRC-ICU, and WHO Severity Classification demonstrated significant association with WHO Severity Classification at 7 days. In univariate analysis, all 4 characteristics showed significant association with mortality; however, only age and SOFA remained significant following multivariate analysis. Conclusion: In the first analysis of medication-related variables as a predictor of severity and in-hospital mortality in COVID-19, MRC-ICU demonstrated acceptable predictive ability as represented by AUROC; however, SOFA was the strongest predictor in both AUROC and regression analysis.
