    Staphylococcus aureus bacteremia, often hospital-acquired and linked to catheters, frequently leads to serious complications and death. Even without endocarditis, this infection poses significant risks to hospitalized patients.

    Area of Science:

    • Infectious Diseases
    • Clinical Microbiology
    • Hospital Epidemiology

    Background:

    • Staphylococcus aureus bacteremia (SAB) is a serious bloodstream infection.
    • Nosocomial infections are a growing concern in healthcare settings.
    • Intravascular devices are common sources of SAB.

    Purpose of the Study:

    • To review complications associated with Staphylococcus aureus bacteremia.
    • To identify common sources and outcomes of SAB.
    • To assess the impact of SAB on morbidity and mortality.

    Main Methods:

    • Retrospective review of 39 consecutive Staphylococcus aureus bacteremia cases.
    • Analysis of patient data, focusing on complications and sources.
    • Evaluation of treatment and outcomes.

    Main Results:

    • 87% of SAB cases were nosocomial, with catheters and dialysis sites being primary sources.
    • 36% of patients experienced complications, including acute events (shock, ARDS, DIC) and metastatic suppurative complications.
    • Four out of six patients with acute complications died; no endocarditis cases were reported.

    Conclusions:

    • Staphylococcus aureus bacteremia is associated with significant morbidity and mortality in hospitalized patients.
    • Catheter-associated bacteremia is common and can lead to severe complications.
    • Effective management often requires prolonged antibiotics and surgical intervention.
