Objective:

To identify specific patterns of metastatic infections in patients with Staphylococcus aureus bacteremia (SAB) to guide clinical management.

Key Findings:
  • 289 (16.7%) patients experienced 439 metastatic infection events within 90 days.
  • 85% of metastatic infections occurred within the first 7 days postdiagnosis.
  • Incidence of metastatic infections was highest in patients with endocarditis (73.4%).
  • The lung was the most frequent metastatic site (23.7%), followed by bones and joints (16.8%) and CNS (12.3%).
Interpretation:

The study highlights the critical role of primary infection focus and timing in the risk of metastatic infections in SAB, enabling targeted management strategies that can improve patient outcomes.

Limitations:
  • Retrospective design may introduce bias, potentially affecting the reliability of the findings.
  • Single-center study limits generalizability, suggesting the need for multi-center studies.
Conclusion:

Findings provide essential insights for clinicians to prioritize surveillance and interventions for patients at high risk of metastatic infections in SAB, emphasizing the need for tailored management approaches.
