Methodology · worked example, guidelines & full notes
GCS-based and more reproducible than Hunt-Hess.
When to use
Standardise SAH severity using GCS and motor deficit.
How it works
Grade I (GCS 15) to V (GCS 3–6), incorporating presence of a major focal deficit at grades II–III.
Key points
- GCS-based and more reproducible than Hunt-Hess.
- Higher grades predict worse outcome.
- Assess after resuscitation/stabilisation.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| WFNS grade | III — GCS 13–14, with motor deficit |
|---|
→WFNS3/5
- Note：Grades IV–V carry high morbidity and mortality.
| WFNS grade | I — GCS 15, no motor deficit |
|---|
→WFNS1/5
- Note：Grades IV–V carry high morbidity and mortality.

FAQ
Frequently asked questions
- What are the limits and cautions when using WFNS Grade (Subarachnoid Haemorrhage)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does WFNS Grade (Subarachnoid Haemorrhage) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is WFNS Grade (Subarachnoid Haemorrhage) calculated in practice? Can you show a worked example?
- Inputs: WFNS grade III — GCS 13–14, with motor deficit → Result: WFNS 3 /5（Note: Grades IV–V carry high morbidity and mortality.） Inputs: WFNS grade I — GCS 15, no motor deficit → Result: WFNS 1 /5（Note: Grades IV–V carry high morbidity and mortality.）
