How this service works
Chopra 2017 Michigan Risk Score for PICC-associated thrombosis: another CVC at PICC placement 1, WBC >12 x10^9/L 1 (12.0 does not score), active cancer 2, PICC lumens single 0 / double 2 / triple 3 (triple includes quad), VTE history never 0 / remote 2 / within 30 days 3 (one field; do not add remote and recent). Max 10. Classes I=0 (observed 0.9%), II=1-2 (1.6%), III=3-4 (2.7%), IV=>4 (4.7% Table 4). Not a PICC order. magent does not count lumens.
Output
Returns a numeric Michigan Risk Score (0–10), the corresponding risk class (I=0, II=1–2, III=3–4, IV=>4), and the published observed PICC-associated thrombosis rate for that class (0.9%, 1.6%, 2.7%, or 4.7%)
Example use cases
Pre-placement PICC thrombosis risk stratification
“My oncology patient is about to get a triple-lumen PICC placed. She has active cancer, her WBC is 15,000 cells/µL, she had a DVT two years ago, and she already has a port in place. What's her Michigan PICC risk score and class?”
Low-risk PICC patient confirmation
“Can you run the Chopra 2017 Michigan score for a patient with a single-lumen PICC, no other central lines, no active cancer, WBC of 8.5 x10^9/L, and no prior VTE history? I want to confirm they're in risk class I.”
Recent VTE patient triple-lumen assessment
“Score the Michigan PICC risk for a patient who had a pulmonary embolism 20 days ago, has a WBC of 11.8 x10^9/L, no active cancer, no other CVCs, and is getting a double-lumen PICC.”

Endpoint
GEThttps://api.magentlab.com/api/calc/michigan_piccWhen to prefer
Use this endpoint when you need to apply the validated Chopra 2017 Michigan Risk Score specifically for PICC-associated venous thrombosis; it is not a generic VTE risk calculator and does not apply to other catheter types. Prefer it over manual calculation to ensure exact published scoring logic (e.g. WBC >12.0 not ≥12.0, vte_history as a single 3-tier field rather than additive remote+recent).
Side effects
- Missing required fields (other_cvc, active_cancer, picc_lumens, vte_history) returns a validation error
- WBC provided outside accepted range (0.01–500 for wbc_k_ul or 10–500,000 for wbc_ul) may return an error or be rejected
- Providing both wbc_k_ul and wbc_ul simultaneously may cause ambiguity; only one should be supplied
- Invalid enum values for picc_lumens or vte_history return a schema validation error
- Payment failure (x402 protocol) prevents the call from completing
