Univariate analysis of clinical features associated with overall 30 day mortality in Staphylococcus aureus blood stream infection episodes.

2 VISA episodes excluded.NOTE: Data are no. (%) of patients, unless otherwise indicated.NA: To prevent survivor treatment bias, analysis of no treatment was not performed.1The principal diagnosis distribution in deceased patients differed significantly compared to patients that survived. This difference was due to a diagnosis of infective endocarditis, pneumonia, device (other) related infection and no identifiable focus. The strength of each of these factors can be found in Table 4.2C-reactive protein and persistent bacteraemia variables were not included in mortality analyses due to a high proportion of missing data.3The 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.4Heteroresistant vancomycin intermediate (hVISA) and vancomycin susceptible (VSSA) Staphylococcus aureus phenotypes determined using population analysis profiling area under the curve method.
