Even in patients who survived a clinical course complicated with multiple organ dysfunction leads to significant morbidity costs and use of already limited resources. That s why treatment of these patients requires timely mobilization of a logical and scientifically up-to-date plan. In critical care as in almost all disciplines of medicine the emphasis on the benefits of an evidence-based medicine approach has caused current guidelines to be based mostly on the results of prospective randomized clinical studies 1 . These studies mostly evaluate differences in mortality among treatment arms. But sepsis and multiple organ failure have a chaotic nature and treatment effects cannot be explained solely on the basis of differences in mortality. That s why we believe that the linear statistical methods currently used in clinical research are not enough to model this chaotic nature. Besides the complex pathophysiologic interactions within inflammatory cascade and coagulation a genetically determined predisposition for sepsis and septic shock is another reason that diverts the clinical course of sepsis and septic shock from one that is linearly predictable. Additionally there is a temporal and dynamic relationship between failing organ systems and therapeutic .
