Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.
The SOFA scoring system is useful in predicting the clinical outcomes of critically ill patients. [8] According to an observational study at an Intensive Care Unit (ICU) in Belgium, the mortality rate is at least 50% when the score is increased, regardless of initial score, in the first 96 hours of admission, 27% to 35% if the score remains unchanged, and less than 27% if the score is reduced.

For every hour a patient is denied AB therapy after the onset of septic shock, the patient's chance of survival is reduced by 7.9% (Survivesepsis.org 2005). The 2012 guidelines differ: Administration of broad-spectrum antimicrobials therapy within 1 hr of recognition of septic shock (1B) and severe sepsis without septic shock. [7]
While most people recover from mild sepsis, the Mayo Clinic says the mortality rate for septic shock "is about 30 percent to 40 percent." Contributing: Adrianna Rodriguez
In the U.S., there are more than 350,000 deaths per year due to sepsis. Ashley Park's recent septic shock offers important lessons.
In a 2014 trial, blood transfusions to keep target hemoglobin above 70 or 90 g/L did not make any difference to survival rates; meanwhile, those with a lower threshold of transfusion received fewer transfusions in total. [71] Erythropoietin is not recommended in the treatment of anemia with septic shock because it may precipitate blood clotting ...
Septic shock begins as sepsis, which is “the body’s dysregulated response to infection,” says Dr. Justin Belsky, assistant professor of emergency medicine at Yale School of Medicine.
Mortality in MODS from septic shock (which itself has a high mortality of 25–50%), and from multiple traumas, especially if not rapidly treated, appear to be especially severe. If more than one organ system is affected, the mortality rate is still higher, and this is especially the case when five or more systems or organs are affected.
