Value 22.1 %
Organism Bacteria Staphylococcus aureus
Reference Blot SI, Vandewoude KH, Hoste EA, Colardyn FA. Outcome and attributable mortality in critically Ill patients with bacteremia involving methicillin-susceptible and methicillin-resistant Staphylococcus aureus. Arch Intern Med. 2002 Oct 28 162(19):2229-35.PubMed ID12390067
Method A highly vancomycin-resistant mutant (MIC = 100 µg/ml) of Staphylococcus aureus, mutant VM, was isolated in the laboratory by a step-pressure procedure, continued to grow and synthesize peptidoglycan in the presence of vancomycin (50 µg/ml) in the medium
Comments The difference between the attributable mortality rates of MSSA bacteremia (1.3%) and MRSA bacteremia (23.4%) was 22.1%. This difference was statistically significant (95% CI, 8.8%-35.3%).
