| Abstract | Background: Staphylococcus aureus is an important cause of resistant infection with high mortality and morbidity. Objectives: We aimed to evaluate the clinical characteristics and comorbidities of patients with S. aureus infection to define the predictors of adverse outcomes. Methods: In this cross-sectional study, patients (aged ≥ 15 years) with positive S. aureus blood cultures were included. Their demographic and clinical characteristics were recorded, and their association with the main adverse outcomes (methicillin-resistant S. aureus [MRSA], infective endocarditis, source of infection, and the final outcome were analyzed using SPSS software version 16. Results: The male-to-female ratio was 54/51. The mean age was 55.13 years (women: 58.45 ± 20.4 and men: 53.6 ± 17.6). Of 105 cases analyzed, 40% had hospital-, 25.7% community-, and 34.3% healthcare-associated bacteremia. The median duration of hospital admission was 13 days. Thirty-two percent had MRSA, differently based on the source of infection (P = 0.029). Twenty-eight patients had infective endocarditis, differently based on the source of infection, prosthetics, considerable foci of infection, and receipt of blood and its derivatives (P < 0.05). Most patients with neurological and end-stage renal disease (both P = 0.001) did not have infective endocarditis. Finally, 61.9% of the patients were discharged with good condition, 38.1% died, and 9% left the hospital before diagnosis of the foci. Conclusions: Vascular catheters and cardiovascular diseases, including hypertension, are among the most common factors associated with S. aureus bacteremia, and it is necessary to carefully examine the presence of these factors, as well as infective endocarditis in these patients. | en |
