Top Ten Causes of Death in the U.S.
1. Heart Disease2. Cancer3. Stroke (Cerebrovascular Disease)4. Chronic lower respiratory disease5. Accidents6. Alzheimer’s Disease7. Diabetes8. Influenza and Pneumonia9. Nephritis, Nephrotic Syndrome, and Nephrosis10. Septicemia

#6 and #8 in neonatal and pediatric age group, respectively
Sepsis is a Common Cause of Death
Sepsis is #1 killer Sepsis is #1 killer worldwideworldwide
Lancet 2010; 375:1969
2008 worldwide data from WHO, UNICEF, and Bill and Melinda Gates Foundation
8.8 million deaths in children <5 years of age68% (5.97 million) due to infectious diseases
Sepsis is the final common pathway in deaths from malaria, dengue fever, pneumonia, HIV/AIDS, and diarrheal illness!

Sepsis recognition is inconsistent at best

Sepsis is a syndrome, not a disease

Minimize variationToo Much Variation in Treatment!
Open Crit Care Med 2010; 3:51
Retrospective analysisN=51 critically ill children with septic shockSignificant variation in duration of treatment, use of weaning taper, duration of taper
Practice variation at CCHMC (informal chart audit):
1. Choice, timing, and duration of antibiotic therapy2. Choice and indication for vasoactive infusions3. Choice and indication of mechanical ventilatory support4. Route and threshold for nutritional support5. Choice of sedative and level of sedation required6. Threshold for Renal Replacement Therapy (RRT)
