How this service works
Spyropoulos 2011 7-factor associative IMPROVE VTE score during hospitalization: previous VTE 3, known thrombophilia 2, lower-limb paralysis 2, current cancer 2, immobilized >=7 days 1, ICU/CCU stay 1, age >60 1. Max 12. Bands: 0-1; 2-3 (observed VTE 1.5%); >=4 (observed VTE 5.7%). Not a VTE diagnosis or prophylaxis order. Not the 4-factor admission predictive model. Not IMPROVEDD. magent does not examine the patient.
Output
Returns the numeric IMPROVE VTE score (0–12), the corresponding risk band (0–1, 2–3, or ≥4), and the observed VTE rate associated with that band (1.5% for band 2–3, 5.7% for band ≥4). Does not provide prophylaxis orders or VTE diagnoses.
Example use cases
ICU patient with prior clot history
“Run the IMPROVE VTE score for a 72-year-old in the ICU who had a DVT two years ago, has no known thrombophilia, no lower-limb paralysis, no active cancer, and has been immobilized for 10 days.”
Cancer patient VTE risk on admission
“What's the IMPROVE VTE score for a 58-year-old hospitalized patient with active cancer and known thrombophilia, no prior VTE, not in ICU, not paralyzed, and immobilized for only 3 days?”
Elderly immobilized patient stratification
“Score this 80-year-old patient on the IMPROVE VTE model — they've been immobilized for 8 days, no prior VTE, no cancer, no thrombophilia, no lower-limb paralysis, not in ICU or CCU.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/improve_vteWhen to prefer
Use this endpoint when you need to compute the validated Spyropoulos 2011 7-factor IMPROVE VTE score specifically — not the 4-factor admission predictive model, not IMPROVEDD, and not other VTE scoring systems (e.g. Caprini, Padua, DASH). Prefer this for hospitalized medical patients where clinical flags have already been assessed by a clinician and need to be converted into a standardized numeric score and risk band.
Side effects
- Missing required query parameter returns validation error
- Age outside 18–120 range may be rejected or return unexpected results
- Boolean parameters passed as strings instead of true/false may fail
- Caller-assigned clinical flags that are clinically inaccurate will produce a score reflecting those inputs, not the true clinical state
