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

A nationwide cohort of 15,423 critically ill COVID-19 patients admitted to intensive care units in mainland France between February 2020 and June 2021. The data was collected by Santé publique France and analyzed by Antoine Journé to investigate factors associated with mortality, severe ARDS, ICU-free days, and need for invasive ventilatory support. The study stratifies patients by age group (<45, 45–64, ≥65 years) and the first three pandemic periods.

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 different waves of the pandemic.
• Investigating sex-based disparities in COVID-19 severity and mortality.

Strengths

• Nationwide coverage of ICU admissions in mainland France.
• Analysis of 15,423 patients with a mean age of 64.1 years.
• Stratified analysis by three age groups and three distinct pandemic periods.
• Examines multiple outcomes: mortality, severe ARDS, ICU-free days, and invasive support.

Limitations

• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The 25.2 KB file size suggests the provided document is likely a summary or supplementary file, not the full dataset.
