Novel β-lactam/β-lactamase inhibitor combinations versus alternative antibiotics in adults with hospital-acquired pneumonia or ventilator-associated pneumonia: an integrated analysis of three randomised controlled trials.

Objectives: This study assessed the efficacy and safety of novel β-lactam/β-lactamase inhibitor (BL/BLI) combinations in adult patients with hospital-acquired pneumonia (HAP) or ventilator-associated pneumonia (VAP).

Methods: PubMed, Web of Science, the Cochrane Library, Ovid MEDLINE, Embase and EBSCO databases were searched for randomised controlled trials (RCTs) published before 13 September 2020. Only RCTs comparing the treatment efficacy of novel BL/BLI combinations with other antibiotics for HAP/VAP in adult patients were included in this integrated analysis.
