Background Methicillin-susceptible Staphylococcus aureus (MSSA) bacteraemia is a common and serious infection, associated with significant morbidity and high mortality rates. Antistaphylococcal penicillins (ASPs) have traditionally been recommended as the first-line treatment. However, this established position has recently been challenged by meta-analyses suggesting that cefazolin may provide comparable efficacy, along with a more favourable safety profile. Further clinical and real-world studies are warranted to substantiate these findings.
Objectives The aim of this study was to assess the effectiveness and safety of cefazolin compared with ASPs in the management of MSSA bacteraemia.
