Ceftolozane-tazobactam Versus Meropenem for ESBL and AmpC-producing Enterobacterales Bloodstream Infection

Summary

The purpose of this study is to determine whether ceftolozane-tazobactam is as effective as meropenem with respect to 30 day mortality in the treatment of bloodstream infection due to third-generation cephalosporin non-susceptible Enterobacterales or a known chromosomal AmpC-producing Enterobacterales (Enterobacter spp., Citrobacter freundii, Morganella morganii, Providencia spp. or Serratia marcescens).
