Baux Score (Burn Mortality Estimate)
Baux score (Baux 1961): a burn mortality estimate equal to age + burned %TBSA; a value near 100 was near-universally fatal in the pre-modern era, with modern burn care shifting survivable thresholds higher.

Example
- Age
- 40 years
- Burned total body surface area
- 30 %TBSA
Result: Baux score 70 — lower predicted mortality.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 100
- Lower predicted mortality (age + %TBSA).
- >= 100
- Historically near-universally fatal; survivable with modern intensive burn care. A prognostic estimate, not a triage order.
What you enter
- Age
- Burned total body surface area
