Revised Baux score

Combines the three main determinants of burn mortality in one number: age, burn extent and inhalation injury.

Method · Limits of application

Revised Baux/Osler 2010: age+TBSA+17 inhalation injury; original logistic model

The revised Baux sums age, percentage of burned area and 17 for inhalation injury. The raw total is not a mortality percentage: probability requires the version’s logistic transformation. The simplified model performed worse than the more complex model in the article and requires interpretation in the appropriate clinical population.

Conditions of use

Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.

Sources and documentation

Documented formula

Transcribed from the source or a recorded revision; this is not a clinical recommendation.

Revised Baux = age (years) + TBSA burned (%) + 17 × inhalation injury (1=yes, 0=no).

In Osler’s model (39888 burn patients in the US registry), age and TBSA had almost equal weights; inhalation injury equalled 17 years or 17% TBSA. Death probability comes from logistic transformation of the score.
