Previous VTE
Known thrombophilia
Lower-limb paralysis
Current cancer
Immobilised ≥ 7 days
ICU/CCU stay
Age > 60
When to use
Decide on thromboprophylaxis in medical inpatients.
How it works
Weighted items: prior VTE 3, thrombophilia 2, lower-limb paralysis 2, cancer 2, immobilised ≥ 7 days 1, ICU/CCU 1, age > 60 1.
Key points
- Score 0–1 identifies low VTE risk (prophylaxis may be withheld).
- ≥ 2–3 supports pharmacologic prophylaxis.
- Pair with the IMPROVE bleeding risk score.
