Methodology · worked example, guidelines & full notes
Extends range to 1, capturing the worst injuries.
When to use
Add prognostic discrimination at the low end of the GCS.
How it works
GCS-P = total GCS − Pupil Reactivity Score (both reactive 0, one 1, none 2). Range 1–15.
Key points
- Extends range to 1, capturing the worst injuries.
- Improves TBI outcome prediction.
- Easy bedside extension of the GCS.

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.
| Total GCS | 10 3–15 |
|---|---|
| Pupils unreactive to light | One unreactive (−1) |
→GCS-P9/15
- Severity:Moderate
- Formula:GCS − Pupil Reactivity Score (0/1/2)
| Total GCS | 10 3–15 |
|---|---|
| Pupils unreactive to light | Both reactive (−0) |
→GCS-P10/15
- Severity:Moderate
- Formula:GCS − Pupil Reactivity Score (0/1/2)

FAQ
Frequently asked questions
- What are the limits and cautions when using GCS-Pupils Score (GCS-P)?
- 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 GCS-Pupils Score (GCS-P) 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 GCS-Pupils Score (GCS-P) calculated in practice? Can you show a worked example?
- Inputs: Total GCS 10 3–15, Pupils unreactive to light One unreactive (−1) → Result: GCS-P 9 /15(Severity: Moderate, Formula: GCS − Pupil Reactivity Score (0/1/2)) Inputs: Total GCS 10 3–15, Pupils unreactive to light Both reactive (−0) → Result: GCS-P 10 /15(Severity: Moderate, Formula: GCS − Pupil Reactivity Score (0/1/2))
