Podcast #333: TBI Prognosticators

Author: Michael Hunt, MD

Educational Pearls:

  • Studies have shown that patients with decreasing GCS scores have worse outcomes, however GCS of 4 has worse outcome than GCS 3.
  • Alternative scoring system is the GCS-P score which is GCS score – number of non-reactive pupils.
  • GCS3 50% mortality 70% poor outcome at 6 months; GCS-P of 1 had mortality 74% and poor outcome at about 90% at 6 months.
  • GCS-P score is a better prognostic indicator than GCS score.
