Table 4 Univariate and multivariate analyses of risk factors associated with mortality in patients with nosocomial MRSA bacteremia using logistic regression

From: Nosocomial methicillin-resistant Staphylococcus aureus (MRSA) bacteremia in Taiwan: Mortality analyses and the impact of vancomycin, MIC = 2 mg/L, by the broth microdilution method

Characteristic Univariate OR 95% CI p-value Multivariate ORa 95% CI p-value
High vancomycin MIC 2.59 1.07-6.30 0.035 3.76 1.34-10.54 0.012
Malignancy 3.48 1.57-7.74 0.002 3.06 1.15-8.17 0.025
Pneumonia 1.82 0.83-3.99 0.137    
Cardiothoracic surgery 2.30 0.75-7.09 0.146 5.66 1.52-21.12 0.010
Charlson score 1.27 1.06-1.52 0.009 1.25 1.01-1.55 0.045
Endocarditis 4.50 0.79-25.69 0.09    
Bedridden 3.19 1.12-9.08 0.03    
Cerebrovascular disease 2.52 0.88-7.26 .086    
ICU admission 2.27 1.05-4.91 .037    
  1. a: Covariates having a p < 0.2 were included in the stepwise regression, and covariates with a higher p-value were discarded.
