Multivariate analysis of risk factors associated with overall 30 day mortality in Staphylococcus Aureus blood stream infection episodes.

1Reference group composed of all principle diagnoses with similar 30 day mortality.2The effect of vancomycin MIC determined by E-test on mortality for patients treated with vancomycin. Similar results were obtained for the total group and when MIC was determined by broth microdilution.3Heteroresistant vancomycin intermediate (hVISA) Staphylococcus aureus phenotype determined using population analysis profiling area under the curve method.
