How is the Baux score interpreted?

A Baux score of 100 historically suggested ~50% mortality. The Revised Baux adds 17 for inhalation injury. Scores >140 carry very high mortality, while modern burn care has shifted the 50% threshold to higher values.

Is the Baux score still clinically useful?

The Baux Score remains a simple, validated, and widely used triage tool in burns, though modern burn units use it alongside the ABSI or ABA burn outcome tools for more precise prognostication.

Baux Score — Burn Mortality Prediction (Age + %TBSA)

Calculate the Baux Score (age + percent TBSA burned) and Revised Baux Score (age + %TBSA + 17 if inhalation injury) to quickly estimate burn mortality probability at the bedside.
