Intracerebral Hemorrhage

🩺What is Intracerebral Hemorrhage?

The ICH Score was developed by Hemphill et al. and published in Stroke in 2001. It was derived from a cohort of 161 patients with spontaneous ICH at the University of California, San Francisco. The score assigns 0-2 points for GCS (GCS 13-15 = 0, GCS 5-12 = 1, GCS 3-4 = 2) and 0-1 point for each of: age ≥80, infratentorial origin, ICH volume ≥30 mL, and intraventricular hemorrhage. Total scores range from 0-6, with each point increase associated with a stepwise increase in 30-day mortality: 0 (0%), 1 (13%), 2 (26%), 3 (72%), 4 (97%), and 5-6 (100%). The score has been externally validated in multiple cohorts worldwide and is widely used in clinical practice for prognostication, treatment decisions (including surgical candidacy), and clinical research. The original study reported an area under the ROC curve of 0.85 for 30-day mortality prediction.

📊Clinical Assessment & Risk Scoring

Healthcare professionals use these validated clinical calculators, diagnostic scales, and risk scoring systems to assess the severity, prognosis, or therapeutic dosing requirements for Intracerebral Hemorrhage:

• ICH Score — Intracerebral Hemorrhage Severity & Mortality

  The ICH (Intracerebral Hemorrhage) Score is a validated clinical grading scale that predicts 30-day mortality in patients with spontaneous intracerebral hemorrhage, based on five independent predictors: Glasgow Coma Scale score, age ≥80 years, infratentorial origin, ICH volume ≥30 mL, and intraventricular hemorrhage.

🧬Diagnostic Logic & Scoring Breakdown

The ICH score is calculated by summing points from 5 components: (1) GCS score: 13-15 = 0 points, 5-12 = 1 point, 3-4 = 2 points. (2) Age ≥80 years: 1 point. (3) Infratentorial origin (cerebellar or brainstem): 1 point. (4) ICH volume ≥30 mL on initial CT (calculated using ABC/2 method): 1 point. (5) Intraventricular hemorrhage (IVH) present: 1 point. Total score 0-6. Each increasing point corresponds to higher 30-day mortality. The score is most useful for standardizing prognosis communication, identifying patients who may benefit from aggressive intervention (scores 1-2), and guiding goals-of-care discussions (scores 4-6).

📢Clinical Significance & Implications

The ICH Score is the most widely used prognostic scale for spontaneous intracerebral hemorrhage, endorsed in the AHA/ASA Guidelines for the Management of Spontaneous Intracerebral Hemorrhage. It provides a simple, rapid, and reproducible method for predicting 30-day mortality at the bedside using only clinical and initial CT findings. The score has been externally validated in over 10,000 patients across multiple international cohorts with consistent performance (AUC 0.82-0.92). Beyond mortality prediction, the ICH Score correlates with functional outcome at 30 days and 6 months, and higher scores (≥4) are associated with poor functional outcomes in >90% of survivors. The score is used to guide treatment decisions including the appropriateness of intensive care, surgical evacuation (particularly for cerebellar hemorrhages), and goals-of-care discussions. However, the ICH Score should not be used in isolation for withdrawal of care decisions, as it provides prognostic information at the population level and individual outcomes may vary. Other prognostic factors such as GCS score trajectory, hematoma expansion, and patient preferences should also be considered.

💡 Clinical Assessment Scenario Example

A 75-year-old male with history of hypertension on warfarin for atrial fibrillation presents with acute onset right-sided weakness and aphasia. His blood pressure is 185/105 mmHg. GCS on arrival is 10 (E3 V3 M4). CT head without contrast shows a left putaminal hemorrhage measuring 5.0 × 4.5 × 3.5 cm. The estimated ICH volume by ABC/2 method is (5 × 4.5 × 3.5)/2 = 39.4 mL. There is no intraventricular extension. The hemorrhage is supratentorial. Age is <80 years. ICH Score: GCS 5-12 = 1 point, Age <80 = 0, Supratentorial = 0, Volume ≥30 mL = 1, No IVH = 0. Total ICH Score = 2/6. Predicted 30-day mortality: 26%. The patient is admitted to the neurological ICU. Warfarin is reversed with vitamin K and 4-factor PCC. His BP is controlled with IV nicardipine. After discussion with neurosurgery, the decision is made for medical management given the deep location and absence of significant mass effect. A goals-of-care discussion is initiated with the family.

💊Common Medications & Interventions

The following pharmacological therapies and substances are commonly referenced or adjusted based on the clinical assessment of Intracerebral Hemorrhage:

🔗Related Diseases & Conditions

These conditions are clinically associated with Intracerebral Hemorrhage through shared risk-scoring calculators and assessment tools:

• Intraventricular Hemorrhage
• Hypertensive Emergency

⚠️Clinical Assessment Pitfalls

• ❌ Mistake: Using ICH Score for traumatic ICH (contusions)

  ✅ Correction: The ICH Score was derived and validated only for spontaneous (non-traumatic) intracerebral hemorrhage. For traumatic brain injury with contusions, use the Marshall CT classification or Rotterdam CT score.

• ❌ Mistake: Not accounting for IVH when present on CT

  ✅ Correction: IVH may be subtle on CT, especially layering in the occipital horns of the lateral ventricles. Carefully evaluate all ventricular spaces on the CT scan. The presence of IVH increases mortality risk and scores 1 point.

• ❌ Mistake: Using ICH Score for withdrawal of care decisions in isolation

  ✅ Correction: The ICH Score provides population-level mortality estimates, not individual predictions. Many patients with scores of 3-4 survive with acceptable functional outcomes. Scores should be used as one component of a comprehensive assessment including patient wishes, clinical trajectory, and family input.

🚑When to Seek Medical Attention

This reference supports clinical assessment of Intracerebral Hemorrhage; it does not replace urgent evaluation. Seek prompt in-person medical care if symptoms are severe, rapidly worsening, or life-threatening, or if you are unsure about a diagnosis or treatment plan. Patients should always consult their physician before starting or changing any therapy.
