We conducted a retrospective study of 99 patients with methicillin-suseptible Staphylococcus aureus catheter-related bacteremia in which vancomycin MIC was determined by Etest. High vancomycin MIC (>1.5 μg/mL) was the only independent risk factor for development of complicated bacteremia caused by methicillin-susceptible S. aureus (odds ratio 22.9, 95% confidence interval 6.7–78.1).

Several studies have established a relationship between high vancomycin MIC and a worse prognosis for patients with bacteremia caused by methicillin-resistant Staphylococcus aureus (MRSA) (1–5). However, to our knowledge, the role that a high vancomycin MIC could play in the clinical course of a patient with methicillin-susceptible S. aureus (MSSA) bacteremia, has not been investigated, although a high vancomycin MIC has been also reported for strains of MSSA (6).
