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

15,423 critically ill COVID-19 patients admitted to intensive care in mainland France between February 2020 and June 2021. This nationwide cohort study by Antoine Journé investigates factors like obesity and male sex associated with mortality, severe ARDS, and need for invasive respiratory support across three pandemic periods and three age groups. Mortality remained high throughout all periods, but the use of invasive respiratory support decreased over time.

Use Cases

• Modeling mortality risk based on patient age, sex, and pandemic period.
• Analyzing associations 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 mortality in ICU patients.

Strengths

• Nationwide cohort of 15,423 ICU patients provides a substantial sample size.
• Covers three distinct pandemic periods over 17 months (February 2020 to June 2021).
• Analyses are stratified by three predefined age groups (<45, 45–64, ≥65 years).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown for the underlying data file, which may limit suitability assessment.
• The dataset is very small (17.4 KB), suggesting it may be a summary or supplementary document rather than the full raw data.
