ICH Score Calculator

How to Use ICH Score Calculator

The ICH Score Calculator focuses on how to estimate intracerebral hemorrhage severity from GCS, hematoma volume, location, age, intraventricular extension, and blood pressure. Follow these steps:

1. Enter the Glasgow Coma Scale score from the neurologic assessment
2. Enter hematoma volume in mL from imaging or ABC/2 volume estimation
3. Select infratentorial location and intraventricular hemorrhage only when those findings are documented
4. Enter age and systolic blood pressure, then review the total score and each point source

Formula & Theory — ICH Score Calculator

The ICH Score Calculator uses the following calculation logic:

ICH score = GCS points + volume points + location points + age points + IVH points + severe SBP points

GCS points:
GCS 13–15 = 0
GCS 5–12  = 1
GCS 3–4   = 2

Other points:
hematoma volume ≥ 30 mL        = 1
infratentorial hemorrhage      = 1
age ≥ 80 years                 = 1
intraventricular hemorrhage    = 1
systolic blood pressure ≥ 180  = 1

The ICH Score Calculator follows the structure of bedside intracerebral hemorrhage severity scoring: depressed consciousness, larger hematoma volume, infratentorial bleeding, older age, and intraventricular extension all increase the score. The requested blood-pressure input is treated as an additional severe hypertension flag so it is visible rather than hidden.

Use Cases for ICH Score Calculator

The ICH Score Calculator is most useful in these situations:

• Stroke unit teaching and emergency neurology case review.
• Explaining why two hemorrhages with similar volume may have different risk scores.
• Checking imaging-derived values before entering them into a clinical note.
