Development and Validation of the Sequential Organ Failure Assessment (SOFA)-2 Score.

JAMA·December 16, 2025·PMID 41159833

Why it matters

The original SOFA score has been unchanged for 30 years and may not reflect modern ICU practices. SOFA-2 offers a data-driven update that better captures current organ dysfunction patterns and mortality risk, potentially improving prognostication and research comparability in critical care.
