Abstract Background Meropenem-vaborbactam is a recent and promising option for the treatment of KPC-producing Klebsiella pneumoniae (KPC-Kp) infections, including those resistant to ceftazidime-avibactam. Methods We conducted retrospective analysis observational data from 19 Italian hospitals on use outcomes patients treated with meropenem-vaborbactam at least ≥24 hours KPC-Kp infections. Crude propensity-weighted multiple Cox regression models were performed ascertain risk factors independently associated 30-day mortality.
