Model of Santaniello et al for Predicting Mortality in a Patient with Combined Burn and Trauma Injury

Description

Santaniello et al developed a model for predicting mortality in a patient with combined burn and trauma injury. The authors are from Loyola University Medical Center and the National Trauma Data Bank.


 

Parameters:

(1) Injury Severity Score (ISS)

(2) age in years

(3) percent body surface area (BSA) with burns (severity of burns not specified)

(4) inhalation injury (0 if absent, 1 if present)

 

X =

= (0.137 * (ISS)) + (0.02 * (age)) + (0.003 * (percent BSA)) - (0.495 * (points for inhalation injury)) - 5.25

 

probability of mortality =

= (1 / (1 + EXP((-1) * X)))
