Objective: The purpose of this study was to determine the value of R-Baux and P-Baux indexes in predicting the pediatric burn outcome. Using prospective cross-sectional method, 213 children under 12 years old admitted with burn in burn referral hospital in Northwest of Iran were included in the study. Data were collected using goal-driven questionnaire including patients' demographics and burn clinical data and outcome. Results: About 59.6% of participants were male. The most common causes of burns was burning with boiling water (127; 69%). For outcome of death, the AUC for the scores of P.Baux and R.Baux were same with 0.959. The AUC for death were 982% and 992% for P.Baux and R.Baux respectively. Also, for the outcome of admission to ICU the AUC were same with 959%. A significant relation between R-Baux and P-Baux scores with patients need for intubation was determined based on logistic regression (p=0.01). Conclusions: The R-Baux and P-Baux scores were related to the probability of intubation, ICU admission and mortality. Using these scores not only predicts mortality risk, but also provide the opportunity for health providers to prioritize patients and provide proper facilities and services to prevent child mortality due to burn.
