Comparison of the revised Shock Index multiplied by the Glasgow Coma Scale and the Trauma and Injury Severity Score for predicting survival in paediatric patients with trauma: a nationwide retrospective cohort study in Japan

The rSIG demonstrated higher predictive accuracy for in-hospital survival among paediatric patients with trauma than TRISS. These findings suggest that rSIG is a more effective prognostic tool for paediatric trauma care. Validation and the establishment of age-specific cut-off values are warranted to enhance its clinical applicability.
