Prognosis value of revised Baux score among burn patients in developing country

The aims of this study was to determine prognosis value of revised Baux score for burn patients in developing country. A retrospective study was conducted on all burn hospitalized patients at National Burn Hospital, Hanoi, Viet Nam during a period from 01/1/2015 to 31/12/2019. Collected criteria included age, burn extent, inhalation injury, death or survive, Baux and revised Baux score of each patients. AUC and SMR was compared between two scores. Prognosis value of revised Baux score was also classified according to age groups. The results showed that AUC of revided Baux score was significantly higher than that of Baux score (0.96 vs. 0.95; p=0.001). SMR of revised Baux score was closer to 1 than that of Baux score (1.03 vs. 1.14 respectively). For revised Baux score, AUC was highest in adult patients (0.98±0.01) followed by elderly and pediatric patients. In addition, SMR was 0.99 in adult group, 0.77 in elderly patient and was 4.36 in pediatric patients. In conclusion, the revised Baux score is more accurate than the Baux score but should only be recommended to apply in prognosis for adult and elderly burn patients in developing country.
