In 2002, the Surviving sepsis campaign defined a strategy that aimed to reduce the high mortality due to sepsis. One point of this strategy was a recommendation to recognize that the sepsis is an important cause of deaths and high economic costs in the pediatric intensive care units. Knowledge of the disease is the first step to impact it. There are few studies of the sepsis epidemiology in the world children, and even less in Colombia. Maybe, the most important study in this field was developed in the United States in the nineties. In Latin-America there are others studies, especially in Brazil, but none in Colombia. The authors pretend to do a multicenter study about the epidemiology of the pediatric sepsis in Colombia. A web site has been designed to collect data and to give up-todate information to the local scientific community about this topic: www.sepsisencolombia.com
