Hospital Management and 1-year Outcome of Patients Aged 70 Years and Older With Severe COVID-19

SARS-COV-2 infection can progress to acute respiratory distress syndrome and require hospitalization in the ICU in 5-20% of affected patients. Age is a major risk factor for developing a severe form and for death. ARDS related to SARS-COV-2 has specific features, including the need for long mechanical ventilation and length of stay and the use of corticosteroid therapy. These specificities are responsible for significant morbidity (neuromyopathy, delirium, post-resuscitation syndrome) and mortality during the first wave (46% at 3 months for the population of patients aged 70 years and over). To investigator's knowledge, no study has evaluated the prognosis in the ICU and the long-term functional outcome of elderly people admitted for a severe or critical form of COVID-19 since the major changes in management (dexamethasone, screening for thrombo-embolic complications, use of high-flow oxygen therapy as first-line treatment...). Investigator therefore propose a 1-year follow-up of a cohort of patients aged 70 and over hospitalised in a conventional service or in intensive care for a severe or critical form of COVID-19. The objectives are to describe the prognosis and functional outcome of hospitalized elderly patients with severe COVID-19.
