Sum of eye, verbal, and motor GCS subscores at the time of initial evaluation. Range 3-15.

Whether the hemorrhage extends into the ventricular system, as seen on CT.

ICH Score 1 - estimated 30-day mortality: 13%.

  • In the original Hemphill 2001 study, patients with an ICH Score of 1 had an estimated 30-day mortality of 13%.
  • A GCS of 5-12 contributes 1 point; improving the level of consciousness on serial assessments is a positive prognostic sign.
  • A hematoma volume of 20 mL (< 30 mL) contributes 0 points for the volume criterion.

Next stepLow scores still require careful monitoring, as hematoma expansion can occur in the first 24 hours and alter prognosis significantly.
