Revised Baux Score

Q: What is the significance of the Revised Baux Score (rBaux) in burn patients?

Answer: It provides a good prediction of mortality.

The Revised Baux Score (rBaux) is a formula: 

Age + %TBSA (Total Body Surface Area) Burned + (17 x R)

 - where R is 1 if there is an inhalation injury and 0 if there is none.

Two Examples:

1. For a 40-year-old patient with a 30% TBSA burn and an inhalation injury:

40 (Age) + 30 (%TBSA) + (17 x 1) = 87

2. For the same patient without an inhalation injury: 

40 (Age) + 30 (%TBSA) + (17 x 0) = 70

Numerous online calculators are available through search engines.

In recent years, diabetes has also been suggested as a factor in predicting mortality in burn patients (see reference # 4).
