Formula and scoring

GCS 3–4 = 2, 5–12 = 1, 13–15 = 0; volume ≥30 cm³ = 1; IVH = 1; infratentorial = 1; age ≥80 = 1. Range 0–6.

Exam and ward pearls

  • Derivation 30-day mortality: 0 = 0%, 1 = 13%, 2 = 26%, 3 = 72%, 4 = 97%, 5 = 100%.
  • GCS carries the most weight (up to 2 points); every other item scores 1.

When not to rely on it

  • Derived in a single US centre (UCSF, 1997–98); every patient with score 0 survived and every patient with score 5 died.
  • Mortality for scores 1–4 is taken from a secondary source that quotes the original table; scores 0 and 5 are from the original abstract.
