Clinical and laboratory predictors of mortality in <i>Staphylococcus aureus</i> bacteremia in a high-risk setting: a single-center retrospective analysis of Pitt score, SOFA, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio

High PBS and NLR are strong and independent predictors of mortality in SAB. As this study was conducted in a high-risk cohort with a considerable proportion of critically ill and immunocompromised patients, the findings are particularly relevant to this vulnerable population. External validation in larger, multicenter cohorts is required to confirm their generalizability.
