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 | Both reactive (−0) |
→GCS-P10/15
- Severity：Moderate
- Formula：GCS − Pupil Reactivity Score (0/1/2)
| Total GCS | 10 3–15 |
|---|---|
| Pupils unreactive to light | Both unreactive (−2) |
→GCS-P8/15
- Severity：Severe
- Formula：GCS − Pupil Reactivity Score (0/1/2)
Common questions
What is GCS-Pupils Score (GCS-P)?
Refine coma assessment with the GCS-Pupils score (GCS-P).
How is GCS-Pupils Score (GCS-P) calculated? What is the core formula?
GCS-P = total GCS − Pupil Reactivity Score (both reactive 0, one 1, none 2). Range 1–15.
When is GCS-Pupils Score (GCS-P) used?
Add prognostic discrimination at the low end of the GCS.
What are the key clinical points for GCS-Pupils Score (GCS-P)?
Extends range to 1, capturing the worst injuries. Improves TBI outcome prediction. Easy bedside extension of the GCS.
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.
