Description
Background:
The revised Baux (rBaux) score integrates age, percent total body surface area burned (TBSA), and inhalation injury to estimate mortality following burn injury. While the model yields outstanding performance in general burn populations, the factors influencing mortality among patients with extremely severe burns (Baux >100) remain uncertain. In this group, it is uncertain whether demographic characteristics or injury severity play a greater role in determining survival.
Methods:
A retrospective cohort study was conducted of adult burn patients with Baux scores greater than 100 treated between 2020 and 2024. Demographic variables (age, sex, and race) and injury characteristics (TBSA and inhalation injury) were analyzed. Multivariable logistic regression was used to identify variables independently associated with in-hospital mortality. Adjusted odds ratios (OR) with 95% confidence intervals were calculated.
Results:
A total of 113 patients met the inclusion criteria. In multivariable analysis, TBSA and inhalation injury were independently associated with mortality. Each 1% increase in TBSA increased the odds of death by approximately 5% (OR 1.05, p < 0.001). The presence of inhalation injury was associated with nearly a three-fold increase in mortality risk (OR 2.76, p = 0.04). After adjustment for injury severity, age, sex, and race, none of these factors was significantly associated with mortality.
Conclusion:
In patients with extremely severe burns, mortality was primarily associated with burn size and inhalation injury, while demographic factors were not independently associated with survival. Our results indicate that the physiologic severity of the burn injury may be a stronger determinant of survival than baseline demographic characteristics in patients with Baux scores greater than 100.
