Efficacy of the Sit to Stand Test in the Decision to Hospitalize a Patient Consulting the Emergency Dept for COVID 19

Study Overview
=================
Brief Summary
-----------------
As part of the Coronavirus Infectious Disease 2019 (COVID19) pandemic, the hospital care system is facing a major strain. Patients with SARS-Cov2 (severe acute respiratory syndrome coronavirus 2 ) infection can worsen very quickly, possibly presenting, within hours, severe respiratory failure requiring urgent specialized care. Therefore, it is essential to develop emergency assessment tools to assess relevant criteria to decide which patients must be kept under hospital monitoring and which patients can be treated on outpatient care. The aim of this study is to assess the efficacy of STST in the decision to hospitalize patients consulting emergency department for a SARS-Cov2 infection. The investigators wish to show that the addition of this test to the usual hospitalization criteria reduces the proportion of patients hospitalized 48 hours after their first visit to the emergency department.

Primary Purpose: Screening
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Conventional arm<br>For the patients enrolled in this conventional arm, the decision of hospitalisation or discharge will be taken with usual criteria (pulsed oxygen saturation (SpO2) in room air <92% and respiratory rate> 22/min, respiratory rate> 30/min, Blood gas hypoxemia, decompensation of comorbidity, home monitoring not possible, other intercurrent pathology requiring hospitalization, several risk factors for COVID infection requiring hospitalization in intensive care (age> 65y, hypertension complicated by a cardiovascular event, chronic cardiovascular disease, unbalanced diabetes with complications, chronic respiratory disease (excluding well-controlled asthma), chronic renal failure dialysis, obesity, progressive cancer under treatment, congenital or acquired immunosuppression) | |
| Experimental: Interventional arm<br>For the patients enrolled in this interventional arm, the decision of hospitalisation or discharge will be taken with usual criteria and the result of Sit to Stand Test. | Diagnostic Test: Sit to stand test<br>* The sit to stand test (or STST) is a test consisting of performing as many sit-to-stand tests as possible in one minute, from a chair without armrests. We note before and during this test, the SpO2 (pulsed oxygen saturation) (rest value and minimum value during exercise), heart rate (HR), dyspnea on the modified Borg scale as well as the number of chair lifts performed. completely and minimum SpO2 during the recovery phase. The possible results from this one-minute test are as follows: If SpO2 <90% or appearance of signs of respiratory distress: Immediate stop of the test and hospitalization SpO2 <90% or decrease in SpO2 ≥ 4% during the test or during the recovery period: Hospitalization SpO2 ≥90% and no decrease in SpO2 ≥ 4% during the test or during the recovery period which will be 3 minutes maximum: discharge.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of late hospitalizations, within 48 hours of first discharge from emergency department, and motivated by worsening symptoms secondary to SARS-Cov2 infection. |  | 7 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of immediate hospitalizations after the 1st admission at emergency department. |  | 7 days | 
| Proportion of adverse events related to SARS-Cov2 infection within 7 days of patient inclusion. | The adverse events identified are: medical consultation, readmission to the emergency department, hospitalization, hospitalization in intensive care unit, death. | 7 days | 
| Establish the correlation between the number of chair rises performed on STST and the occurrence of an adverse event. | The adverse events identified are: medical consultation, readmission to the emergency department, hospitalization, hospitalization in intensive care unit, death. | 7 days | 
| Correlation between SpO2 and the occurrence of an adverse event | the difference between the measurement of SpO2 before and after STST will be used to establish the correlation between this difference and the occurrence of an adverse event. | 7 days | 
| Correlation between heart rate (HR) and the occurrence of an adverse event | the difference between the measurement of HR before and after STST will be used to establish the correlation between this difference and the occurrence of an adverse event. | 7 days | 
| Correlation between dyspnea score and the occurrence of an adverse event | the difference between the measurement of dyspnea score before and after STST will be used to establish the correlation between this difference and the occurrence of an adverse event. | 7 days |
