About this study

Data regarding optimal treatment for extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae blood-stream infection are lacking. Observational studies show conflicting results when comparing treatment with combination beta-lactam-beta-lactamase inhibitor and carbapenems. The investigators aim to evaluate the effect of definitive treatment with meropenem vs. piperacillin-tazobactam on the outcome of patients with bacteremia due to cephalosporin-non-susceptible Enterobacteriaceae. The investigators hypothesize that piperacillin-tazobactam is non-inferior to meropenem.
