After scoring: open the scene pack, peer scores, and the matching pathway. Local reference — no HIS write.
- Who it is for
- Adults with suspected acute PE when deciding whether to test further, and risk stratification after confirmation.
- Who it is not for
- PERC must not rule out PE when clinical probability is not already low. Confirmed PE does not return to PERC. PERC is not an atrial-fibrillation tool and not a treatment page.
- Formula and variables
- Wells PE and revised Geneva estimate clinical probability; the version stays as on this page. PERC is used only when probability is already low, to see whether testing can stop. BOVA is only for normal blood pressure. Hestia only answers outpatient eligibility. No new score.
- Result → next step
- If probability is low and every PERC item is negative, stop further PE testing; otherwise test. The treatment column stays empty before confirmation. After confirmation, duration opens the anticoagulation-duration page. That link is not hung on PERC. Numeric dose waits for age, weight, renal function, and pregnancy.No numeric dose until age, weight, renal function, and pregnancy are all known. Pregnancy is contraindication or caution only.Duration after confirmation →

Methodology · worked example, guidelines & full notes
Applies only to haemodynamically stable PE.
When to use
Identify intermediate-risk PE patients who may deteriorate.
How it works
SBP 90–100 (2), troponin elevation (2), RV dysfunction (2), HR ≥ 110 (1). Stage I 0–2, II 3–4, III ≥ 5.
Key points
- Applies only to haemodynamically stable PE.
- Combine with sPESI and biomarkers.

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.
| Systolic BP 90–100 mmHg | No (> 100) |
|---|---|
| Elevated cardiac troponin | No |
| RV dysfunction (echo/CT) | No |
| Heart rate ≥ 110/min | No |
→BOVA0/7
- Stage：Stage I — low (~4% complications)
- Use：Applies only to haemodynamically stable PE; identifies those at higher risk of deterioration.
| Systolic BP 90–100 mmHg | Yes (+2) |
|---|---|
| Elevated cardiac troponin | Yes (+2) |
| RV dysfunction (echo/CT) | Yes (+2) |
| Heart rate ≥ 110/min | Yes (+1) |
→BOVA7/7
- Stage：Stage III — high (~42%)
- Use：Applies only to haemodynamically stable PE; identifies those at higher risk of deterioration.

FAQ
Frequently asked questions
- Does BOVA Score (Intermediate-risk PE) 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 BOVA Score (Intermediate-risk PE) calculated in practice? Can you show a worked example?
- Inputs: Systolic BP 90–100 mmHg No (> 100), Elevated cardiac troponin No, RV dysfunction (echo/CT) No, Heart rate ≥ 110/min No → Result: BOVA 0 /7（Stage: Stage I — low (~4% complications), Use: Applies only to haemodynamically stable PE; identifies those at higher risk of deterioration.） Inputs: Systolic BP 90–100 mmHg Yes (+2), Elevated cardiac troponin Yes (+2), RV dysfunction (echo/CT) Yes (+2), Heart rate ≥ 110/min Yes (+1) → Result: BOVA 7 /7（Stage: Stage III — high (~42%), Use: Applies only to haemodynamically stable PE; identifies those at higher risk of deterioration.）
