🩸 Michigan PICC Thrombosis Risk Score
UseWhen to use: hospitalized nonpregnant medical adults when choosing PICC vs alternatives.
StrataHigher class → higher symptomatic DVT risk; class I is not zero risk.
LimitsWhen not to use: pregnancy or cohorts outside original medical-admiss… · Pitfall: defaulting to triple-lumen PICCs when fewer lumens suffice. · Reconsider device choice in class III–IV.

Methodology · worked example, guidelines & full notes
Five predictors, four classes.
When to use
When to use: hospitalized nonpregnant medical adults when choosing PICC vs alternatives.
How it works
Another CVC 1 + WBC>12 1 + lumens (2→1, 3–4→2) + VTE history (>30d→2, ≤30d→3) + active cancer 3. Classes I–IV by total.
Key points
- Five predictors, four classes.
- Fewest lumens preferred.
- Next: MAGIC/PICC appropriateness; VTE prevention pathway.

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.
| Another CVC present at PICC placement | No (0) |
|---|---|
| WBC > 12.0 ×10⁹/L at placement | No (0) |
| Number of PICC lumens | 2 lumens (1) |
| History of VTE | Yes, >30 days prior (2) |
| Active cancer (chemo or cancer-related admission) | No (0) |

FAQ
Frequently asked questions
- Does Michigan PICC Thrombosis Risk 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 Michigan PICC Thrombosis Risk Score calculated in practice? Can you show a worked example?
- Inputs: Another CVC present at PICC placement No (0), WBC > 12.0 ×10⁹/L at placement No (0), Number of PICC lumens 2 lumens (1), History of VTE Yes, >30 days prior (2), Active cancer (chemo or cancer-related admission) No (0) → Result: Michigan PICC 3 pts（Risk class: III — High, Approx. symptomatic DVT: ~2.7%） Inputs: Another CVC present at PICC placement No (0), WBC > 12.0 ×10⁹/L at placement No (0), Number of PICC lumens 1 lumen (0), History of VTE Never (0), Active cancer (chemo or cancer-related admission) No (0) → Result: Michigan PICC 0 pts（Risk class: I — Low, Approx. symptomatic DVT: ~0.9%）
