[Progress of epidemiology and outcome for sepsis]

Sepsis is an uncontrolled host's response to infection and leads to life-threatening organ dysfunction. Traditional prognostic indicators for short-term mortality, such as intensive care unit (ICU) mortality, hospital mortality, cannot reveal the real and final outcome of sepsis patients. Sepsis patients remain high mortality even several years after hospital discharge, at the same time the quality of life, and the cognitive function were also damaged at varying degrees. Nowadays, studies about long-term quality of life for sepsis were still sparse and further study was still needed. This article aims to explore the epidemiology, short-term and long-term outcome so that it can provide some reference for assessment and intervention of long-term outcome of sepsis.
