Methodology · worked example, guidelines & full notes
Unlike CURB-65 (which predicts mortality), SMART-COP predicts the need for intensive organ support.
When to use
Enter age, then the eight components; the tool scores 0–11 and bands the IRVS risk. In the derivation study, ≥ 3 identified 92% of patients needing IRVS.
How it works
Points: SBP<90 (2), multilobar (1), albumin<35 (1), HR≥125 (1), confusion (1), pH<7.35 (2), tachypnea (≤50 yr ≥25 / >50 yr ≥30: 1), hypoxemia (≤50 yr PaO₂<70/SpO₂≤93/PF<333; >50 yr <60/≤90/<250: 2). Bands: 0–2 low · 3–4 moderate (~1/8) · 5–6 high (~1/3) · ≥7 very high (~2/3).
Key points
- Unlike CURB-65 (which predicts mortality), SMART-COP predicts the need for intensive organ support.
- The respiratory-rate and oxygenation cutoffs differ by age (≤50 vs >50), so the same physiology scores differently in younger patients.
- It is a prediction aid, not a disposition mandate; integrate trajectory, comorbidity, and response to initial therapy.

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 | 60 yr |
|---|---|
| Systolic BP < 90 mmHg | Yes |
| Multilobar involvement on chest X-ray | Yes |
| Albumin < 35 g/L | Yes |
| Respiratory rate | 24 /min |
| Heart rate ≥ 125 bpm | Yes |
| Acute confusion | Yes |
| Oxygenation index type | SpO₂ (%) |
| Oxygenation value | 70 |
| Arterial pH < 7.35 | Yes |
→SMART-COP10/11
- Stratum：Very high risk
- Intensive support (IRVS)：≈ 2 in 3 need IRVS
- Respiratory/oxygenation threshold：>50 yr band

FAQ
Frequently asked questions
- What are the limits and cautions when using SMART-COP (CAP Intensive-Support Prediction)?
- 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 SMART-COP (CAP Intensive-Support Prediction) 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 SMART-COP (CAP Intensive-Support Prediction) calculated in practice? Can you show a worked example?
