IMPROVE_Risk_Score_VTE_guideline v.1
IMPROVE Risk Score for Venous Thromboembolism (VTE) predicts 3-month risk of VTE in hospitalized patients.
To calculate IMPROVE Risk Score and 3-month risk of VTE in hospitalized patients.
Variables and points: 1. Previous VTE: No=0, Yes=3 2. Known thrombophilia: No=0, Yes=2 3. Current lower-limb paralysis: No=0, Yes=2 4. Current cancer: No=0, Yes=2 5. Immobilized ≥7 days (Immediately prior to and during hospital admission.): No=0, Yes=1 6. ICU/CCU stay: No=0, Yes=1 7. Age >60 years: No=0, Yes=1 Formula: Addition of the selected points. Interpretation: IMPROVE Score 0 = 0.4% 3-month VTE risk IMPROVE Score 1 = 0.6% 3-month VTE risk IMPROVE Score 2 = 1.0% 3-month VTE risk IMPROVE Score 3 = 1.7% 3-month VTE risk IMPROVE Score 4 = 2.9% 3-month VTE risk IMPROVE Score 5-10 = 7.2% 3-month VTE risk IMPROVE Score >10 = >7.2% 3-month VTE risk
