ICH Score

Estimates 30-day mortality in spontaneous intracerebral haemorrhage from admission data (Glasgow and CT).

Method · Limits of application

ICH/Hemphill 2001: 5 factors, total 0–6; ABC/2 volume; no automatic treatment decision

An estimate of severity at intracerebral hemorrhage presentation, associated with 30-day mortality in the original cohort. Age and volume are components of the score. The abstract does not demonstrate that a score alone justifies a therapeutic decision or definitive individual prognosis.

Conditions of use

Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.

Documented parameters

Glasgow Coma Scale
Hematoma volume ≥ 30 mL (ABC/2 formula)
Intraventricular hemorrhage
Infratentorial origin
Age ≥ 80 years

3/3 reference cases checked. Numerical tests are not clinical validation.

Sources and documentation

Documented formula

Transcribed from the source or a recorded revision; this is not a clinical recommendation.

Glasgow 3 to 4 = 2 · 5 to 12 = 1 · 13 to 15 = 0; volume ≥ 30 mL = 1; intraventricular extension = 1; infratentorial origin = 1; age ≥ 80 years = 1. Total: 0 to 6.

Volume by ABC/2: A = longest haematoma diameter on the largest-area slice; B = diameter perpendicular to A; C = number of slices with haematoma × slice thickness (cm). Result in mL.
