    Objective: Despite appropriate treatment and early diagnosis methods, Staphylococcus aureus bacteremia (SAB) is still associated with a high mortality rate. This study aims to evaluate the clinical features and approaches to SAB and to analyze the parameters that may affect 7-day and 30-day mortality. Materials and Methods: Adult patients with SAB data between 2011 and 2018 were evaluated retrospectively. Clinical data, patient demographics, and 7-day and 30-day mortality rates were obtained from their medical records.Results: In total, 144 patients were included in the study; 57.6% (83/144) of patients were men, and the mean age was 65.2 +/- 16.5 years. The most common source of infection was the central-line catheter (38.9%), followed by intra-abdominal (21%), respiratory (16.7), infective endocarditis (5.6%), and osteoarticular foci (2.1%). Fifteen percent (15%) of the strains were methicillin resistant. Transthoracic echocardiography (TTE) was performed for 80.6% (116/144) patients. Infectious diseases specialist consultation within 96 hours from blood culture signal was requested in 79.9%. Overall, 7-day mortality was 11.8%, and 30-day mortality was 21.5%. Staying in intensive care units (ICU) increased the risk of 30-day mortality by 1.1 times, and respiratory-focused SAB increased the risk by 4.3 times.Conclusion: SAB is still a big threat. Staphylococcal pneumonia remains a severe infection. Several prognostic factors influence mortality. Identifying the source, ensuring source control, and appropriate initial therapy as soon as possible are critical for reducing mortality and morbidity in SAB.
