Intensive care unit length of stay beyond the first week and 1-year mortality - dutch single centre study in unselected critically ill patients describing long-term survival according to length of stay in conjunction with age

Increasing age and prolonged intensive care unit (ICU) length of stay (LoS) are both associated with in-hospital mortality. Especially older patients with a prolonged ICU stay are often considered to be at high risk for mortality.[1] However the effect of a prolonged ICU LoS in conjunction with age on long-term survival remained to be specified.
