The number of patients aged 80 years and older admitted to the intensive care unit ICU increased during the past decade as has the intensity of care for such patients. Yet many physicians remain reluctant to admit the oldest arguing a squandering of societal resources that ICU care could be deleterious or that ICU care may not actually be what the patient or family wants in this instance. Other ICU physicians are strong advocates for admission of a selected elderly population. These discrepant opinions may partly be explained by the current lack of validated criteria to select accurately the patients of any age who will benefit most from ICU hospitalization. This review describes the epidemiology of the elderly aged 80 years and older admitted in the ICU their long-term outcomes and to discuss some of the solutions to cope with the burden of an aging population receiving acute care hospitalization. Epidemiology The aging of the world s population Current forecasts predict that by 2050 the percentage of the population older than aged 80 years will double Table 1 . By 2050 people aged 80 years and older will represent of the population in Europe 66 147 000 persons 9 35 813 000 persons in North America 3 354 000 persons in Oceania 40 098 000 persons in Latin America and Caribbean 227 916 000 persons in Asia and 21 336 000 persons in Africa 1 . These population trends will lead to an increasing demand for healthcare resources both in terms of number of beds and number of healthcare workers including intensive care. Thus if we maintain our current admission
