Galeiras et al developed a model for predicting mortality in critically-ill burn patients. This can help to identify a patient who may benefit from more aggressive management. The authors are from multiple hospital in Spain and Chile.
Patient selection: critically-ill burn patient
Parameters:
(1) gender
(2) age in years
(3) mechanical ventilation <= 72 hours after admission
(4) total burn surface area as percent of total body surface area
(5) full thickness burn surface area as percent of total body surface area
