COVID-19 ICU Patient Outcomes in France by Age and Pandemic Period, 2020-2021

From February 2020 to June 2021, this nationwide cohort study analyzes 15,423 critically ill COVID-19 patients admitted to intensive care units in mainland France. It investigates factors associated with mortality, severe ARDS, ICU-free days, and need for invasive ventilatory support, stratified by age and pandemic period. The dataset was created by Antoine Journé and is shared under a CC-BY-4.0 license.

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.
• Studying temporal trends in ICU outcomes across the first three waves of the COVID-19 pandemic.
• Investigating sex-based disparities in COVID-19 severity and mortality in ICU patients.

Strengths

• Nationwide cohort of 15,423 patients provides a substantial sample size.
• Covers three distinct pandemic periods from February 2020 to June 2021 for temporal analysis.
• Includes detailed outcome measures: mortality, severe ARDS, ICU-free days, and use of invasive support.
• Analysis is stratified by predefined age groups (<45, 45–64, ≥65 years).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (24.9 KB), suggesting it may be a summary or supplementary file rather than raw patient records.
