What is ICH Score?

▾

Imagine you are sitting in a quiet hospital waiting room. A doctor walks in to talk about your relative who just suffered a sudden stroke caused by bleeding in the brain. In these high-stakes, emotional moments, medical teams need a reliable, objective way to assess the situation and plan the next steps. That is where the Intracerebral Hemorrhage (ICH) Score comes in. Developed by researchers to bring clarity to a chaotic situation, this scoring system acts like a quick, standardized health report card for patients experiencing this specific type of bleeding stroke. But why should you, as a family member or a student, care about a clinical calculator? When a crisis hits, medical jargon like "intracranial pressure" or "hematoma volume" can feel like a foreign language. The ICH Score translates complex brain scans and physical exams into a simple number from 0 to 6. This number helps everyone—from the neurosurgeons in the ICU to the family members gathered around a bedside—speak the same language. It gives you a realistic picture of what to expect over the next 30 days, helping you make deeply personal decisions about care goals and treatment paths. At DigiCalcs, we believe that understanding the math behind medicine empowers you. Whether you are a nursing student prepping for clinical rotations, a paramedic reviewing neurology protocols, or a family member trying to make sense of a loved one's charts, this tool demystifies a critical medical benchmark. By looking at five specific clues—like the patient's age and where the bleeding occurred—this calculator helps replace fear of the unknown with clear, actionable insights.

DigiCalcs delivers precision-engineered tools for engineers and STEM professionals.

Formula

▾
f(x)ICH Score = GCS Points (0, 1, or 2) + ICH Volume Points (0 or 1) + IVH Points (0 or 1) + Infratentorial Origin Points (0 or 1) + Age Points (0 or 1); Total ranges from 0 to 6.

Variable Legend

▾
SymbolImeJedinicaOpis
GCSGlasgow Coma Scale3-15A quick test of how awake and responsive a person is, ranging from fully alert (15) to deep unconsciousness (3).
VICH VolumemLThe estimated amount of blood pooling in the brain tissue, measured in milliliters from a CT scan.
IVHIntraventricular Haemorrhagepresent/absentWhether blood has leaked into the brain's fluid-filled ventricles, which can block normal fluid flow.
IFInfratentorial Originyes/noWhether the bleeding started in the lower brain structures (cerebellum or brainstem) rather than the upper cerebrum.
AAgeyearsThe patient's age in years, with a threshold at 80 years old where risks naturally increase.

How to ICH Score

▾
  1. 1Check the patient's consciousness level using the Glasgow Coma Scale (GCS). A lower score means they are less responsive, which adds more points to our severity score.
  2. 2Measure the size of the bleed on a CT scan (usually using a quick formula called ABC/2). If the volume of blood is 30 milliliters or more (about the size of two tablespoons), add 1 point.
  3. 3Look for blood inside the brain's natural fluid chambers (ventricles). If there is intraventricular hemorrhage (IVH), add 1 point.
  4. 4Check where the bleed started. If it is in the lower, back part of the brain (infratentorial, like the brainstem or cerebellum), add 1 point because this area controls vital functions.
  5. 5Factor in the patient's age. If they are 80 years old or older, add 1 point to reflect the natural vulnerability of an older brain.
  6. 6Add up all the points to get a final score between 0 and 6. Use this score to estimate the 30-day survival probability and guide care planning.

Worked Examples

▾
Example 1Low-Risk ICH
Given:55-year-old, GCS 15, small bleed of 10 mL in the cerebrum, no IVH
Rezultat:ICH Score = 0 — Predicted 30-day mortality 0%

Highly encouraging outlook; standard aggressive medical care is the primary focus.

This is a young patient who is fully awake and alert, with a very small bleed located in the upper brain, and no blood leakage into the ventricles. Because all indicators are at their safest levels, the prognosis is excellent, and the medical team will focus on controlling blood pressure to prevent further bleeding.

Example 2Moderate Risk
Given:72-year-old, GCS 10, deep brain bleed of 35 mL with IVH, supratentorial
Rezultat:ICH Score = 3 — Predicted 30-day mortality 72%

Serious clinical situation; crucial time for family discussions and close ICU monitoring.

The patient is moderately responsive (1 point), has a larger bleed over 30 mL (1 point), and blood has entered the ventricles (1 point). This combination raises the risk significantly, requiring intensive care monitoring and early conversations with the family about the patient's long-term wishes.

Example 3Very High Risk
Given:85-year-old, GCS 4, lobar bleed of 40 mL with IVH, supratentorial
Rezultat:ICH Score = 5 — Predicted 30-day mortality ~100%

Extremely critical prognosis; comfort-focused care and palliative options should be discussed.

This elderly patient (1 point) is in a deep coma (2 points) with a massive bleed (1 point) that has spread to the ventricles (1 point). Given the extremely high predicted mortality, the medical team will work closely with the family to align treatment with the patient's comfort and dignity.

Example 4Cerebellar Bleed
Given:68-year-old, GCS 11, cerebellar bleed of 15 mL, no IVH
Rezultat:ICH Score = 2 — Predicted 30-day mortality 26%

Guarded outlook; requires urgent neurosurgical evaluation due to the bleed's location.

Even though the bleed is small (under 30 mL) and the patient is relatively young, the bleed is located in the lower brain (infratentorial, 1 point) and they have moderate confusion (1 point). Lower brain bleeds can quickly compress the brainstem, so a surgeon needs to evaluate them immediately even if the overall score is moderate.

Real-World Applications

▾
🏗️

In busy emergency rooms and intensive care units, doctors and nurses use this tool to quickly assess a patient's status and decide if they need to be transferred to a specialized neuro-ICU.

🔬

Medical and nursing students use this calculator to practice reading CT scans and physical charts, helping them build a strong, intuitive feel for patient prognosis.

📊

Clinical researchers use the score to group patients with similar stroke severities together, making sure medical trials for new treatments are fair and scientifically accurate.

🏥

Healthcare advocates and family counselors use the calculated risk percentages to help families make incredibly tough, compassionate decisions about end-of-life or comfort care.

Special Cases

▾

Deep Sedation or Intubation

In these situations, the calculator might give a score that is higher than it should be because the patient is asleep from medication, not the brain bleed itself. Doctors must try to assess the GCS before giving sedatives to ensure the calculation is accurate.

Irregularly Shaped Bleeds

If the bleed is highly irregular, star-shaped, or spread out in multiple pockets, this simple formula can overestimate or underestimate the actual volume. In these unique cases, advanced computer software on the CT scanner is much better for finding the true volume.

Patients with Pre-existing Brain Conditions

The ICH Score assumes a typical brain baseline before the bleed. A patient with severe pre-existing damage might have a much harder recovery than their calculated score suggests, requiring the medical team to look closely at their previous quality of life.

Frequently Asked Questions

▾
Q

Why is age 80 a cutoff point in this score?

A

As our bodies age, our brain tissue naturally becomes more fragile, and our ability to bounce back from major trauma decreases. Over the age of 80, the body's natural reserves are lower, making a recovery from a brain bleed more challenging. This is why the formula adds a point for patients in this age group.

Q

What does 'intraventricular hemorrhage' actually mean?

A

Inside your brain, there are open chambers called ventricles filled with protective fluid. If a bleed in the brain tissue leaks into these fluid pathways, it is called intraventricular hemorrhage. This can block the natural flow of brain fluid, causing dangerous pressure buildup, which is why it adds a point to the score.

Q

Can this calculator be used for a head injury from a car accident?

A

No, this specific calculator is only validated for spontaneous bleeds, which are usually caused by high blood pressure or weak blood vessels. Bleeds caused by physical trauma, like car accidents or falls, behave differently and are evaluated using different medical tools.

Q

Should doctors use this score to decide on a Do Not Resuscitate (DNR) order?

A

Definitely not on its own. While the score helps predict outcomes, writing a DNR or withdrawing care too early based solely on a high score can lead to a self-fulfilling prophecy. Every patient deserves a personalized evaluation that looks at the whole picture, not just a single calculated number.

Q

How accurate is this score in real-world hospitals?

A

The ICH Score is highly respected and widely validated across many different hospitals and patient groups globally. It has proven to be a very reliable predictor of 30-day survival. However, it is always used as a guide alongside the clinical judgment of the medical team.

Common Mistakes to Avoid

▾
  • !Giving up too early: Using a high score to immediately stop active treatment without giving the patient a chance to stabilize first.
  • !The ruler slip-up: Using the radius instead of the full diameter when doing the ABC/2 math to find the bleed volume, which throws off the whole calculation.
  • !Sedation confusion: Calculating the GCS score while the patient is under the influence of strong pain meds or sedatives.
  • !Forgetting to update: Relying solely on the admission score and ignoring how the patient is doing 24 to 48 hours later when things might have stabilized.
  • !Using it for injuries: Applying this calculator to brain bleeds caused by physical trauma, like a fall or a sports injury, where the math doesn't apply.
💡

Pro Tip

When measuring the bleed volume, always check the slice thickness on the CT scan. Using thinner slices (like 1 to 2 millimeters) makes your volume estimation much more accurate than using thick 5-millimeter slices.
