PURPOSE: This study aimed to evaluate the prognostic value of the BIG score in predicting mortality and functional outcomes in pediatric patients with traumatic brain injury (TBI).
METHODS: A retrospective analysis was conducted on pediatric TBI patients admitted to the Pediatric Intensive Care Unit (PICU) between 2020 and 2024 at a tertiary hospital. Functional outcomes at discharge were assessed using the Functional Status Scale (FSS). Receiver operating characteristic (ROC) analysis determined the predictive accuracy of the BIG score, Pediatric Trauma Score (PTS), Pediatric Glasgow Coma Scale (pGCS), and Pediatric Risk of Mortality III (PRISM III).
RESULTS: A total of 103 patients were included. The mortality rate was 13.6% (n = 14), and 21.4% of survivors had functional impairment at discharge. In non-survivors, the BIG score, PTS, pGCS, and PRISM III were significantly elevated (all p < 0.001). The AUC for predicting mortality was 0.966 (BIG score), 0.911 (PRISM III), 0.909 (pGCS), and 0.827 (PTS). For functional impairment, the AUC values were 0.815 (BIG score), 0.812 (pGCS), 0.715 (PRISM III), and 0.645 (PTS). Correlation analysis showed a strong association between FSS scores and mechanical ventilation duration (r = 0.786, p < 0.001) and PICU length of stay (r = 0.706, p < 0.001).
CONCLUSION: The BIG score is a rapid, reliable predictor of mortality and functional outcomes in pediatric TBI patients, outperforming pGCS in patients with an initial pGCS of 3. Prospective studies are needed for further validation.
