Organisation and timeline of measures in French psychiatric establishments during the first wave of the COVID-19 epidemic: EvOlu'Psy study.

Background: The onset of COVID-19 required rapid organisational changes in the mental health domain. Most mental health-care departments appear to have set up infection control measures and also organised planning, coordination and measures that enabled them to provide psychiatric care in a restrictive environment. Our objective was to assess the organisation by psychiatric facilities in France of their response to COVID-19, during the first wave.
