ICH Score Prognosis Worksheet

About the ICH Score Prognosis Worksheet

The Intracerebral Hemorrhage (ICH) Score is a simple prognosis scale for spontaneous intracerebral hemorrhage. It combines five variables that are usually available early in care: Glasgow Coma Scale category, hemorrhage volume, intraventricular extension, infratentorial location, and age 80 or older.

The score is useful because it gives clinicians and families a common language for discussing risk. It is not useful as a stand-alone treatment rule. Bleed expansion, hydrocephalus, posterior fossa compression, anticoagulation status, premorbid function, and the direction of the neurologic exam often matter just as much as the score itself.

This page therefore keeps the score in its proper role: a prognosis worksheet. It shows the component breakdown and the historical mortality context from the original cohorts, while staying away from pretending that one number can decide ICU, surgery, or goals-of-care decisions by itself.

When This Page Helps

The ICH score gives a fast, standardized way to summarize hemorrhage severity. Used carefully, it can improve communication and prognostic framing without turning one score into a treatment decision.

How to Use the Inputs

1. Choose the GCS category used in the original ICH score.
2. Indicate whether the hemorrhage volume is at least 30 cm³.
3. Mark whether intraventricular hemorrhage is present.
4. Mark whether the bleed is infratentorial in origin.
5. Indicate whether the patient is at least 80 years old.
6. Review the total score with the historical 30-day and 12-month mortality context.
7. Use the monitoring and neurosurgical sections as discussion context rather than procedural instructions.

Example Calculation

Tips & Best Practices

• Revisit the prognosis discussion if the neurologic exam, repeat imaging, or hydrocephalus status changes.
• Keep the original score separate from questions about transfer, surgery, or procedure timing.
• Posterior fossa bleeds and ventricular extension often change bedside urgency even when the total score is not extreme.
• Document how the volume estimate was obtained if the ABC/2 method was used.
• Use the score with other tools and the clinical trajectory rather than in isolation.

Self-Fulfilling Prophecy Risk

One of the most important cautions in hemorrhage prognostication is self-fulfilling prophecy. If a severe score is treated as proof that recovery is impossible, early limitation of care can make the predicted outcome come true. That is why modern interpretation of the ICH score emphasizes its role as a prognosis aid, not a stand-alone decision rule.

Why the Original Score Still Matters

Newer tools can incorporate more imaging detail, anticoagulation exposure, or functional outcomes, but the original ICH score remains widely used because it is quick and reproducible. It provides a shared starting point for discussing severity even before more nuanced data are available.

What the Score Leaves Out

Important factors such as hematoma expansion, hydrocephalus, pre-existing disability, anticoagulation reversal, and response to early neurocritical care are not built into the original score. Those missing pieces are exactly why the score should be read as one layer of context rather than the whole answer.

Frequently Asked Questions

• What is the ICH score used for?

  It is mainly used as a short prognosis worksheet after spontaneous intracerebral hemorrhage. It summarizes severity and helps frame discussions, but it does not replace imaging review, neurologic reassessment, or bedside judgment.

• How is hemorrhage volume measured?

  The common quick estimate is the ABC/2 method on CT: A is the largest diameter, B is the largest perpendicular diameter, and C reflects the number of slices with hemorrhage multiplied by slice thickness. It is an approximation, but it is practical and widely used.

• Should care ever be limited based only on the ICH score?

  No. Prognostic scores can contribute to self-fulfilling prophecy if they are treated like a stand-alone answer. The score should support discussion, not determine whether a patient receives full initial stabilization and ongoing reassessment.

• Why does intraventricular hemorrhage matter?

  Blood in the ventricles is associated with worse outcomes because it can contribute to hydrocephalus, inflammation, and additional injury beyond the primary parenchymal bleed.

• Why does infratentorial location matter so much?

  Posterior fossa hemorrhages can become dangerous at smaller volumes because of the limited space around the brainstem and cerebellum. That is why location influences the score even without any other added variable.

• How does anticoagulation change the picture?

  Anticoagulation can increase the risk of hematoma expansion and complicate prognosis, but it is not part of the original ICH score. Reversal strategy depends on the agent involved and the treating team’s emergency pathway rather than on the score alone.
