From: Influence of severity of infection on the effect of appropriate antimicrobial therapy for Acinetobacter baumannii bacteremic pneumonia

  Univariable Analysis Multivariable Analysis
Characteristic OR (95% CI) P-value OR (95% CI) P-value
Hematologic malignancy 3.21 (1.38–7.48) .004   
Cerebrovascular accident 0.42 (0.24–0.74) .003 0.40 (0.20–0.81) .011
Immunosuppressant use 2.21 (1.35–3.61) .002 1.73 (0.95–3.16) .072
Recent surgery 0.44 (0.27–0.73) .001 0.50 (0.27–0.92) .025
Carbapenem resistance 3.02 (1.84–4.96) <.001   
Extensive drug resistance 3.05 (1.95–4.76) <.001 3.19 (1.86–5.46) <.001
Previous ventilator use 1.96 (1.27–3.02) .002   
APACHE II score (categorical) 3.47 (2.57–4.68) <.001 3.20 (2.33–4.39) <.001
Appropriate antimicrobial therapy 0.49 (0.32–0.76) .001 0.57 (0.34–0.97) .04
  1. All biologically plausible variables with a p-value < 0.05 in the univariable analysis were considered for inclusion in the logistic regression model in the multivariable analysis. A stepwise selection process was utilized. We found that only cerebrovascular accident, recent surgery, extensive drug resistance, APACHE II score, and appropriate therapy were statistically significant factors for 14-day mortality
