Elucidating the Symptomatic, Explanatory and Prognostic Characteristics of GERIAtric Patients Hospitalized for COVID-19

Study Overview
=================
Brief Summary
-----------------
Statement : The emerging Coronavirus 2019 (COVID-19) disease, linked to the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pathogen, has been spreading worldwide since December 2019, affecting millions of people and causing hundreds of thousands of deaths, particularly among the elderly. The first epidemiological evidence available reveals a different expression of the disease in the elderly, associated with a high risk of delayed diagnosis and implementation of protective measures and a particularly high morbidity and mortality, especially among the frailest. To date, there is no effective model for predicting the severity of COVID-19 in an individual. The investigators hypothesize that there are specificities of COVID-19 in the elderly, both etiological, diagnostic and prognostic, all of which are not yet known and understood.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Medical history and co-morbidities | listing of medical history and co-morbidities data provided by the physician and the family during hospitalization | baseline | 
| The physical examination data, and reports of relevant investigations data provided by the physician and the family during hospitalization | The demographic characteristics are age, sex, marital status, place of life, career, presence of un/formal assistance, … | baseline | 
| Electrocardiography QT Interval | all electrocardiograms performed during hospitalization | baseline | 
| Number of different therapeutic classes | Number of different therapeutic classes taken per day. | baseline | 
| Comprehensive Geriatric Assessment (CGA) | Comprehensive geriatric assessment (CGA) is defined as a multidisciplinary diagnostic and treatment process that identifies medical, psychosocial, and functional capabilities of an older adult in order to develop a coordinated plan to maximize overall health with aging. CGA is based on the premise that a systematic evaluation of frail older persons by a team of health professionals may identify a variety of treatable health problems and lead to better health outcomes. | baseline | 
| Biological parameters | Characterization of the COVID-19 impact on the biological parameters evaluated by blood test. | baseline | 
| Medical imaging results | Assessment of lesion extension (percent) with medical imaging results (thoracic scan) | baseline | 
| Diagnosis of COVID-19 | Recovery of the diagnosis method (PCR or thoracic scan) | baseline | 
| Length of hospitalization |  | at the 3-month follow-up | 
| Number of death from any cause |  | at the 3-month follow-up | 
| Reports of relevant investigations data provided by the physician and the family during the two-month telephone follow-up | The demographic characteristics are age, sex, marital status, place of life, career, presence of un/formal assistance, … | at the 3-month follow-up | 
| Length of hospitalization |  | at the 12-month follow-up | 
| Number of death from any cause |  | at the 12-month follow-up | 
| Reports of relevant investigations data provided by the physician and the family during the two-month telephone follow-up | The demographic characteristics are age, sex, marital status, place of life, career, presence of un/formal assistance, … | at the 12-month follow-up |
