    GCS-Pupils Score

    Combines GCS and pupil reactivity for greater accuracy at low GCS.
    When to Use
    Pearls/Pitfalls

    Patients with traumatic brain injury.

    • Retrospectively derived, based on pooled data from two large databases, IMPACT and CRASH. 
    • Addition of pupil data was shown to be particularly useful at very low GCS scores (3-4), likely because of higher frequency of abnormal pupil response in patients with severe TBI and low GCS (Brennan 2018).
