COVID-19 ICU Patient Outcomes in France by Age and Pandemic Period

15,423 critically ill COVID-19 patients admitted to intensive care units in mainland France between February 2020 and June 2021. This nationwide cohort study from Santé publique France investigates factors like age, sex, and obesity associated with mortality, severe ARDS, and use of invasive respiratory support across the first three pandemic periods. The dataset was authored by Antoine Journé and last updated in April 2026.

Use Cases

• Modeling mortality risk based on patient age, sex, and pandemic period.
• Analyzing the association between obesity and severe ARDS or need for invasive respiratory support.
• Comparing ICU-free days and treatment outcomes across different waves of the pandemic.
• Investigating sex-based disparities in COVID-19 severity and outcomes in intensive care.

Strengths

• Nationwide cohort of 15,423 patients provides a substantial sample size.
• Covers three distinct pandemic periods over 17 months (Feb 2020–Jun 2021) for temporal analysis.
• Includes detailed outcome measures: mortality, severe ARDS, ICU-free days, and use of invasive respiratory support.
• Stratified analysis by predefined age groups (<45, 45–64, ≥65 years) allows for age-specific insights.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is very small (17.3 KB), suggesting it may be a summary or supplementary file rather than the full patient-level data.
• Data is limited to mainland France, which may limit generalizability to other regions.
