Introduction: Even though France was severely hit by the COVID-19 pandemic, few studies have addressed the dynamics of the first wave on an exhaustive, nationwide basis. We aimed to describe the geographic and temporal distribution of COVID-19 hospitalisations and in-hospital mortality in France during the first epidemic wave, from January to June 2020.
Methods: This retrospective cohort study used the French national database for all acute care hospital admissions (PMSI).
Objective: To explore mortality risk factors for patients hospitalised with COVID-19 in a critical care unit (CCU) or a hospital care unit (HCU).
Design: Retrospective cohort analysis using the French national () database.
Setting: Any public or private hospital in France.
