Sequential Organ Failure Assessment for ICU patients.
Use the worst value in the past 24 hours for each organ. Mortality bands are approximate hospital mortality by highest SOFA score in 1990s ICU cohorts (Vincent, Crit Care Med 1998) and are population estimates, not individual predictions; current ICU mortality differs.

Sofa Score is built on published formulas and reference ranges from established health sources. We revisit it periodically as guidance evolves; the "Last reviewed" date above shows when that last happened. If something looks wrong, tell us with the feedback button in the bottom-right corner.
No. Sofa Score gives you a general estimate based on the inputs you provide, not a diagnosis. Existing conditions, medications, and individual history all change what a number actually means for you. Treat this as a starting point for a conversation with a doctor or other qualified health professional, not a substitute for one.
