The outcome prediction of patients with extensive burns is essential in determining clinical decisions. Various burn mortality prediction models have been developed, and burn mortality had decreased markedly with the improvement in burn management.
This study aimed to compare the effectiveness of revised Baux score (RBS) and abbreviated burn severity index (ABSI) in predicting mortality of burn injury patients. This was a retrospective cross-sectional method. The subjects of the study were 111 medical records of burn patients who were treated in the Burn Unit of a tertiary health care in Yogyakarta, Indonesia, from 2015 to 2016.
There were 111 patients, of whom 81 were males and 30 females. The outcomes of burn injury patients were 97 survived, and 14 died. There were significant association between percentage of total body surface area burned, and inhalation injury with the ABSI score of ≥ 8. The patients with an ABSI score of ≥ 8 have a relatively higher risk by 4.1-fold to die compared with patients who scored < 8, but statistically did not reach a significant level. In contrast, the patients with an RBS score ≥ 60 have a relatively lower risk by 2.43-fold to die compared with the patients with a score of < 60, but statistically, the results did not reach a significant level.
In conclusions, ABSI and RBS score systems are simple to calculate, and ABSI is more accurate for prediction of acute burn injury. Presence of inhalation injury and large TBSA were significant predictors of mortality.
