ICH score to predict 30-day mortality after spontaneous ICH

Component	ICH score points
GCS score* at presentation
3 to 4	2
5 to 12	1
13 to 15	0
ICH volume on initial imaging
≥30 cm³	1
<30 cm³	0
Intraventricular extension of ICH
Present	1
Absent	0
Infratentorial origin of ICH
Yes	1
No	0
Age (years)
≥80	1
<80	0
Total	0 to 6

The ICH score results range from 0 to 6, with higher scores being associated with higher predicted mortality risk. The predicted 30 day mortality is 13% for an ICH score of 1, 26% for score of 2, 72% for a score of 3, 97% for a score of 4, and 100% for a score of 5. In the initial cohort, no patient with an ICH score of 0 died and none had a score of 6.

ICH: intracerebral hemorrhage; GCS: Glasgow coma scale.
