Impact of vancomycin minimum inhibitory concentration on mortality among critically ill patients with methicillin-resistant Staphylococcus aureus bacteremia.

We retrospectively evaluated 99 intensive care unit patients with methicillin-resistant Staphylococcus aureus bacteremia to determine whether having a vancomycin minimum inhibitory concentration (MIC) of 2 mg/L affected mortality. This MIC was found in 5.1% of patients and was associated with the probability of death (adjusted odds ratio, 13.9 [95% confidence interval, 1.1-171.2]) independent of other factors.
