  1. Effects of different factors on outcome in a mixed ICU population for study population (N = 709) by using univariate logistic regression analyses. Parameters found to be relevant on a P < 0.05 level for ICU mortality entered multivariate logistic regression analysis. Quality of regression model tested with the Hosmer-Lemeshow test, indicating good calibration (χ2 = 4.672; P = 0.792). BSI, bloodstream infection; SOP, standard operating procedure; TISS-28, therapeutic intervention scoring system-28.
  2. aSeptic shock entered multivariate analysis due to correlation; bDifficult-to-treat pathogens include bacteria associated with potential intrinsic or acquired resistance (methicillin-resistant Staphylococcus aureus, germs producing extended spectrum betalactamases, vancomycin-resistant Enterococci, nonfermenters like Pseudomonas spp., Stenotrophomonas maltophilia, Acinetobacter baumanii, Citrobacter spp., Enterobacter cloacae, Enterococcus faecium, and Bacillus cereus).
