Definition of HOME-CoV rule:
The Delphi method is used to reach a consensus of a large panel of experts and to define an easy-to-use clinical rule aiming to help emergency physicians in hospitalisation or outpatient management decision making : the HOME-CoV rule.
The impact of the rule implementation is evaluated in a before and after study:
* before period: observational assessment of current practices
* implementation period : educational lectures, posters, and pocket cards showing and explaining HOME-CoV rule are communicated to participating Emergency Departments.
* after period : observational assessment of practices
In each period, patients consulting Emergency Departments with suspected or probable COVID-19 are evaluated for potential inclusion. Clinical, biological and imaging data that may be involved in decision-making about hospitalization are collected as well as the physician final decision (hospitalization or outpatient management) and its main determinants.
A phone-call follow-up is performed and the clinical status according to the Ordinal Scale for Clinical Improvement of COVID-19 from the World Heath Organization is collected on day 7 and day 28 following inclusion.
