Extending international sepsis epidemiology: the impact of organ dysfunction

Abstract

In the previous issue of Critical Care, Blanco and colleagues contributed to a growing body of literature on the international epidemiology of severe sepsis. Taken together, these studies confirm that the sepsis incidence is high, that the development of organ dysfunction is a major determinant of mortality and that the occurrence of organ dysfunction is influenced by chronic comorbid medical conditions. It is clear that early detection of organ dysfunction and serial sequential organ dysfunction scoring provides us with the best chance to optimize clinical care. Identifying factors that contribute to the development of organ dysfunction in sepsis will lead to the development of new treatment modalities that will reduce mortality. Future studies must therefore focus on the impact of new treatment modalities for preventing progression to multiple organ dysfunction syndrome and consequent mortality in sepsis.
