Recent progress in sepsis epidemiology – have we learned enough?

The encouraging results of recent clinical trials on therapy of severe sepsis and septic shock are paralleled by ongoing studies on the epidemiology of sepsis and infection in intensive care unit patients all over the world. The development of network-based systems for assessing morbidity and mortality in intensive care unit patients has contributed to a significant improvement in quality of care. Data from the SOAP (Sepsis Occurrence in the Acutely Ill Patient) study demonstrate that the treatment of septic patients varies widely, and that even those strategies that have been evaluated are not yet implemented in routine practice. Hence, activities on surveillance and education still merit further attention.
