COVID-19 ICU Patient Outcomes in France, February 2020 to June 2021

Antoine Journé's nationwide cohort study analyzes 15,423 critically ill COVID-19 patients admitted to intensive care units in mainland France. The data, last updated in April 2026, investigates factors associated with mortality, severe ARDS, ICU-free days, and need for invasive ventilatory support across the first three pandemic periods. The study stratifies analyses by age groups and identifies associations with obesity and male sex.

Use Cases

• Modeling mortality risk in ICU patients based on pandemic period and demographic factors mentioned in the description
• Analyzing the association between obesity and severe ARDS outcomes across different age groups

• Investigating sex-based disparities in COVID-19 ICU outcomes as highlighted in the results

Strengths

• Nationwide scale covering all ICU admissions in mainland France managed by Santé publique France
• 15,423 patient records with a mean age of 64.1 years and 70% male demographic
• Covers three distinct pandemic periods from February 2020 to June 2021, enabling temporal analysis
