Introduction: Burns represents a significant global health challenge, causing considerable morbidity and mortality.
Accurate prognostication is crucial for optimal burn care management.
This study compared the accuracy of the BOBI and R-Baux scores in predicting mortality among burn Methods: This retrospective study analyzed data from 46 burn patients treated at Dr.
Mohammad Hoesin General Hospital Palembang.
Patient demographics, burn characteristics, and mortality outcomes were BOBI and R-Baux scores were calculated for each patient.
Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Youden Index were determined for both scores.
Agreement between the scores was assessed using the Kappa statistic.
