ich_score: Intracerebral Hemorrhage (ICH) Score

Description

Calculates the ICH Score to estimate 30-day mortality in patients with spontaneous intracerebral hemorrhage. The score is a simple clinical grading scale ranging from 0 to 6, derived from the Glasgow Coma Scale (GCS), ICH volume, presence of intraventricular hemorrhage (IVH), infratentorial origin, and age.

Usage

ich_score(gcs_score, ich_volume_cm3, intraventricular_hemorrhage,
          infratentorial_origin, age_years)

Value

A list containing:

ICH_Score

The calculated total score (Range 0-6).

Est_30_Day_Mortality

Estimated 30-day mortality percentage based on the derivation cohort.

Arguments

gcs_score

Numeric. Glasgow Coma Scale score on admission (3-15). 3-4: +2 pts. 5-12: +1 pt. 13-15: 0 pts.

ich_volume_cm3

Numeric. Volume of the hematoma in cubic centimeters. (>= 30 cm3 adds 1 point).

intraventricular_hemorrhage

Numeric (0 or 1). Presence of intraventricular hemorrhage. (1 = Yes, +1 point).

infratentorial_origin

Numeric (0 or 1). Is the hemorrhage infratentorial in origin (e.g., brainstem, cerebellum)? (1 = Yes, +1 point).

age_years

Numeric. Patient age in years. (>= 80 years adds 1 point).

Examples

# Example 1: High Mortality
# GCS 4 (+2), Vol 40 (+1), IVH Yes (+1), Infratentorial Yes (+1), Age 85 (+1)
# Score = 6
ich_score(4, 40, 1, 1, 85)

# Example 2: Low Mortality
# GCS 15 (0), Vol 10 (0), No IVH (0), Supratentorial (0), Age 60 (0)
# Score = 0
