Variations in Organism-Specific Severe Sepsis Mortality in the United States

Abstract

We not only confirmed an overall decline in severe sepsis mortality from 1999 to 2008 but also identified previously unreported variations in organism-specific severe sepsis mortality. Gram-negative organisms predominate, whereas anaerobes and methicillin-resistant S. aureus are significant predictors of mortality. Future clinical trials exploring new treatments in severe sepsis should incorporate individual organism trends to elucidate potential effect on mortality.
