🚑 Rapid Emergency Medicine Score (REMS)
UseWhen to use: adult medical ED triage/disposition when vitals and GCS are known.
StrataHigher REMS → higher in-hospital mortality OR (~1.4 per point in derivation).
LimitsWhen not to use: as sole trauma score. · Pitfall: mixing with NEWS2 trigger thresholds. · Recheck after resuscitation.

When to use
When to use: adult medical ED triage/disposition when vitals and GCS are known.
How it works
Age 0–6 + MAP/HR/RR/SpO₂/GCS each 0–4 (max 26).
Key points
- 0–26.
- Bedside only.

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.
| Age | 55–64 (+3) |
|---|---|
| MAP (mmHg) | 70–109 (0) |
| Heart rate | 70–109 (0) |
| Respiratory rate | 12–24 (0) |
| SpO₂ | 86–89% (+1) |
| GCS | 8–10 (+2) |

FAQ
Frequently asked questions
- Does Rapid Emergency Medicine Score (REMS) 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 Rapid Emergency Medicine Score (REMS) calculated in practice? Can you show a worked example?
- Inputs: Age 55–64 (+3), MAP (mmHg) 70–109 (0), Heart rate 70–109 (0), Respiratory rate 12–24 (0), SpO₂ 86–89% (+1), GCS 8–10 (+2) → Result: REMS 6 /26（Cue: Intermediate REMS — heightened monitoring / disposition caution） Inputs: Age <45 (0), MAP (mmHg) ≤49 (+4), Heart rate ≤39 (+4), Respiratory rate ≤5 (+4), SpO₂ >89% (0), GCS 14–15 (0) → Result: REMS 12 /26（Cue: Intermediate REMS — heightened monitoring / disposition caution）
