    Pediatric Trauma BIG Score

    Stratifies severity of illness and predicts mortality in pediatric patients after trauma.


    Use on admission in pediatric patients <18 years old who have sustained blunt or penetrating trauma or penetrating blast injury. Use lab values obtained on admission.

    When to Use
    Why Use

    Pediatric patients under 18 years of age, after blunt or penetrating trauma or penetrating blast injury.

    • BIG is an acronym for the components of the score: base deficit, INR, and GCS.
    • Initial analysis (Borgman 2011) had more penetrating trauma and penetrating blast injuries, compared with the excluded patients who had more blunt injuries and burns. These were accounted for in the external validation, however.
    • May facilitate communication regarding prognosis with families and during patient transfer (Davis 2015).
    • If point of care testing is used, INR and base deficit results can be obtained in ~2 minutes (Borgman 2015).
    • Simple, rapid, and accurate scoring system to evaluate the severity of illness and predict mortality in children.
    • Can be applied to both blunt and penetrating traumatic injuries.
    • Useful in quantifying degree of physiological derangement beyond clinical appearance and GCS alone. Base deficit and INR are physiologic measures of hypoperfusion and trauma-induced coagulopathy, respectively, and both play critical roles in trauma-related mortality.
