Comparison of the Effectiveness and Safety of Linezolid and Daptomycin in Vancomycin-Resistant Enterococcal Bloodstream Infection: A National Cohort Study of Veterans Affairs Patients

摘要

Treatment with daptomycin for vancomycin-resistant enterococcal bloodstream infection resulted in significantly lower treatment failure, 30-day mortality, microbiologic failure, 7-day mortality, and duration of bacteremia in comparison to linezolid.Methods.aEuro integral This was a national retrospective cohort study comparing linezolid and daptomycin for the treatment of VRE-BSI among Veterans Affairs Medical Center patients admitted during 2004-2013. The primary outcome was treatment failure, defined as a composite of (1) 30-day all-cause mortality; (2) microbiologic failure; and (3) 60-day VRE-BSI recurrence. Poisson regression was conducted to determine if antimicrobial treatment was independently associated with clinical outcomes.
