About the ICH score

The ICH score is a practical bedside severity tool used to summarize several important features of spontaneous intracerebral hemorrhage. It combines age, initial level of consciousness, hemorrhage volume, intraventricular extension, and infratentorial location into a single numeric estimate. Clinicians often use it because it is easy to calculate, easy to communicate, and useful for framing early discussions about severity. It does not replace a neurologic examination, a review of imaging, or specialist judgment, but it helps teams quickly describe how serious a presentation appears at first contact. A major strength of the score is that it brings together information from both the patient examination and the CT scan. The Glasgow Coma Scale contributes heavily because consciousness level is strongly associated with outcome. Hemorrhage volume matters because larger bleeds generally produce more mass effect and tissue injury. Intraventricular hemorrhage often indicates extension into the ventricular system and can worsen hydrocephalus risk. Infratentorial hemorrhage is important because bleeding in the brainstem or cerebellum can threaten vital functions or narrow spaces very quickly. Age is included because older patients often have less physiologic reserve and may face a more complicated recovery course. This calculator uses the scoring rules provided for this tool, then maps the final score to a mortality table for a rough 30-day estimate. A mortality percentage should never be treated as a personal prediction or as the only basis for treatment decisions. Outcomes vary with blood pressure control, hematoma expansion, time to diagnosis, surgical options, anticoagulation reversal, intensive care support, rehabilitation access, and many patient-specific details that are not part of the score. Small differences in CT measurement or in the initial neurologic assessment can also change the score. Use the result as a communication aid and a teaching aid, not as a stand-alone verdict. A low score does not guarantee a good recovery, and a high score does not define the limits of meaningful treatment. Families and clinical teams still need individualized discussions that include imaging trends, patient goals, comorbid conditions, and the broader neurologic picture.

InputOutputNote
58 years, GCS 14, volume 12 cm³, no IVH, supratentorialScore 0 → 0% mortalityA mild presentation with preserved consciousness and a smaller bleed.
72 years, GCS 10, volume 35 cm³, IVH present, supratentorialScore 3 → 72% mortalityVolume, depressed consciousness, and IVH contribute; age <80 scores 0.
84 years, GCS 4, volume 45 cm³, IVH present, infratentorialScore 6 → 100% mortalityA very high-risk pattern using the capped score table in this tool.

Frequently asked questions

What does the ICH score help with?
It provides a quick severity summary for spontaneous intracerebral hemorrhage and supports early communication about prognosis and triage. The score was developed and validated to help clinicians make consistent, evidence-based decisions in emergency and neurology settings.
Is the mortality percentage a personal prediction?
No. It is a rough estimate based on score groups, not a guarantee of what will happen to a specific patient.
Why are IVH and infratentorial location included?
Both features are associated with worse outcomes because they may increase hydrocephalus risk, mass effect, or compromise in tight anatomic spaces. Including them allows the score to capture dimensions of severity that simple volume or GCS alone do not reflect.
Can the score replace imaging review or neurology consultation?
No. It is a summary tool only and should be interpreted alongside CT findings, examination changes, and specialist input.
Why does this calculator cap the result at 6?
The mortality lookup supplied for this tool ends at 6, so the displayed score is capped there to keep the output aligned with the provided table. Scores above 6 are not possible under the original scoring criteria because the maximum contribution from all five variables is exactly 6 points.
