🦠 MuLBSTA Viral Pneumonia Score
UseWhen to use: influenza-like / viral pneumonia severity cue.
Strata0–5 lower; 6–11 intermediate; ≥12 higher mortality band in derivation.
LimitsWhen not to use: as sole ICU triage for COVID without local calibrati… · Pitfall: missing bacterial coinfection. · Pair with CURB-65/PSI/SCAP.

How it works
Multilobar +5, lymphopenia≤0.8 +4, bacterial coinfection +4, smoking +3, HTN +2, age≥60 +2.
Key points
- 0–20.
- ≥12 higher-risk cue.
- Next: CURB-65 / SCAP.

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.
| Multilobar infiltrates | No (0) |
|---|---|
| Lymphocyte ≤0.8×10⁹/L | No (0) |
| Bacterial coinfection | No (0) |
| Smoking history | No (0) |
| Hypertension | No (0) |
| Age ≥60 years | No (0) |
→MuLBSTA0/20
- Cue：0–5 — lower mortality band in derivation
| Multilobar infiltrates | Yes (+5) |
|---|---|
| Lymphocyte ≤0.8×10⁹/L | Yes (+4) |
| Bacterial coinfection | Yes (+4) |
| Smoking history | Yes (+3) |
| Hypertension | Yes (+2) |
| Age ≥60 years | Yes (+2) |
→MuLBSTA20/20
- Cue：≥12 — higher mortality band — consider higher acuity care

FAQ
Frequently asked questions
- Does MuLBSTA Viral Pneumonia Score 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 MuLBSTA Viral Pneumonia Score calculated in practice? Can you show a worked example?
- Inputs: Multilobar infiltrates No (0), Lymphocyte ≤0.8×10⁹/L No (0), Bacterial coinfection No (0), Smoking history No (0), Hypertension No (0), Age ≥60 years No (0) → Result: MuLBSTA 0 /20（Cue: 0–5 — lower mortality band in derivation） Inputs: Multilobar infiltrates Yes (+5), Lymphocyte ≤0.8×10⁹/L Yes (+4), Bacterial coinfection Yes (+4), Smoking history Yes (+3), Hypertension Yes (+2), Age ≥60 years Yes (+2) → Result: MuLBSTA 20 /20（Cue: ≥12 — higher mortality band — consider higher acuity care）
