Organ dysfunction is a condition where an organ does not perform its expected function. Organ failure is organ dysfunction to such a degree that normal homeostasis cannot be maintained without external clinical intervention or life support. It is not a diagnosis. It can be classified by the cause, but when the cause is not known, it can also be classified by whether the onset is chronic or acute.

Multiple organ failure can be associated with sepsis and is often fatal. Countries such as Spain have shown a rise in mortality risk due to a large elderly population there.{{cite journal |vauthors=Bouza C, López-Cuadrado T, Saz-Parkinson Z, Blanco J | title=Epidemiology and recent trends of severe sepsis in Spain: a nationwide population-based analysis (2006-2011). | journal=BMC Infect Dis | year=2014 | volume=14 | issue=1| pages=717| doi= 10.1186/s12879-014-0717-7| pmid=25528662 | pmc=4327809 | doi-access=free }} There are tools physicians use when diagnosing multiple organ failure and when prognosing the outcome.
