1032. Are enterococcal blood stream infections an independent risk factor for a poorer 5-year survival or just a marker for severity of illness? - The Munich Multi-Centric Enterococci cohort

BACKGROUND: To assess the long-term survival of patients with enterococcal bloodstream infections (BSI), encompassing various species and resistance patterns, in comparison to Escherichia coli (E. coli) BSI.

Sumario:BACKGROUND: To assess the long-term survival of patients with enterococcal bloodstream infections (BSI), encompassing various species and resistance patterns, in comparison to Escherichia coli (E. coli) BSI. Recruitment process [Figure: see text] Graphical Abstract [Figure: see text] METHODS: Between 2010 and 2019, 3,290 enterococcal and 3,415 E. coli BSI were retrospectively screened in seven hospitals in Munich, Germany. All vancomycin (VRE), vancomycin/linezolid (LVRE), and linezolid (LRE) resistant Enterococcus faecium (ECFM) BSI were included. Enterococcus faecalis (ECFA), vancomycin/Linezolid-susceptible ECFM, and E. coli BSI were randomly assigned. Cox-regression models were used to assess survival as the primary endpoint and were adjusted for limiting prognostic factors, which were measured for their importance using a random forest model (RFM). RESULTS: 952 patients with 916 episodes of enterococcal BSI and 193 E. coli BSI episodes were analysed. RFM identified multimorbidity and markers for disease severity as most indicative of low survival in enterococcal BSI. The 5-year survival was significantly lower for enterococcal BSI than for E. coli BSI (23.9% vs. 42.3%; p< 0.001). This difference remained significant in the Cox-regression analysis after adjusting for 17 prognostic factors and excluding patients with limited life expectancy (metastatic tumour disease, Charlson comorbidity index ≥5). Adjusted 5-year survival between E. coli and ECFA was similar but significantly different between ECFA and ECFM BSI (29.2% vs. 21.7%; p=0.002). The analysis conducted on monomicrobial ECFM and VRE BSI indicated that their respective 5-year survival was similar (19.6% vs. 21.2%; p=0.753). CONCLUSION: ECFM BSI seems to be an independent risk factor for poor long-term survival. However, additional vancomycin resistance does not appear to be a contributing factor.
