> The ICH score calculator estimates 30-day mortality after a spontaneous intracerebral haemorrhage from the Glasgow Coma Scale, haemorrhage volume, intraventricular extension, location and age.

## Inputs

- Glasgow Coma Scale
- ICH volume ≥ 30 mL
- Intraventricular haemorrhage
- Infratentorial origin
- Age 80 or over

## Results

- ICH score
- 30-day mortality

## Formula

```
Score = sum of the points for each item
```

## Explanation

The ICH score was published by Hemphill in 2001 and is the most widely used prognostic score for brain haemorrhage. It should support, not replace, clinical judgement, and early do-not-resuscitate decisions based on it alone are discouraged.

### How to use the ICH Score Calculator

- **Glasgow Coma Scale**
- **ICH volume ≥ 30 mL**
- **Intraventricular haemorrhage**
- **Infratentorial origin**
- **Age 80 or over**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Each answer carries the points shown in the published score. The calculator adds them up and maps the total to the published interpretation.

### Scoring table

ItemAnswers and pointsGlasgow Coma Scale13–15 = 0; 5–12 = 1; 3–4 = 2ICH volume ≥ 30 mLNo = 0; Yes = 1Intraventricular haemorrhageNo = 0; Yes = 1Infratentorial originNo = 0; Yes = 1Age 80 or overNo = 0; Yes = 1

### What each result means

- **ICH score** = [Glasgow Coma Scale] + [ICH volume ≥ 30 mL] + [Intraventricular haemorrhage] + [Infratentorial origin] + [Age 80 or over]
- **30-day mortality** = interp([ICH score], 0, 1, 0, 13, 26, 72, 97, 100, 100)

## Worked example

Inputs — Glasgow Coma Scale: 13–15; ICH volume ≥ 30 mL: No; Intraventricular haemorrhage: No; Infratentorial origin: No; Age 80 or over: No.

Results — **ICH score = 0 / 6**; 30-day mortality = 0 %.

## Key terms

- **ICH**: Intracerebral haemorrhage.

## FAQ

**How is ICH volume measured?**
With the ABC/2 method on CT – see the ICH volume calculator.

**What is a high ICH score?**
3 or more carries a high mortality in the original study.

**Has treatment improved outcomes?**
Yes – modern care has lowered mortality at each score level.
