Mortality, Gravity Predictive Factors and Clinical Evolution of Older COVID-19 Patients in Short Geriatric Services.

Study Overview
=================
Brief Summary
-----------------
Since the beginning of the year 2020, clinical characteristics of a new disease as the global COVID-19 epidemic has spread in France. People over 70 years of age are the more concerned by this virus in proportion and in gravity with some atypical first symptoms compared to younger patients. Evolution of the disease is variable from forms with few symptoms to severe forms sometimes quickly lethal. GERICOVID LYON is a descriptive analysis of all patients over 70 years of age hospitalised for COVID-19 in short geriatric unities of University Hospital of Lyon This study will allow more comprehension about COVID-19 in older people. The role of predictive factors, pre-existing comorbidities and the nature and frequency of complications in a short period will be investigate. Treatments practices will be analysed too.
