Admission of elderly patients to intensive care

Elderly patients have an increased probability of dying after treatment in an intensive care unit (ICU), compared with younger patients. The risk of dying is largely determined by the admission type (patients with planned admissions have a better prognosis than those with unplanned admissions), severity of illness and functional status prior to admission. Elderly patients surviving ICU often experience a decline in functional status. No data are available on the factors that predict functional outcome. Elderly patients do not necessarily prefer life-sustaining treatment to palliative care. The willingness to undergo ICU treatment depends on the likelihood of survival and beneficial functional outcome. New prognostic models should be developed specifically to predict both survival and functional outcome in individual elderly patients after admission to ICU.
