IMPROVEDD Risk Score for Venous Thromboembolism (VTE)
Predicts risk of VTE in hospitalized patients, adding D-dimer to IMPROVE Risk Score.
Advice
- Results should complement, not replace, clinical judgment and individual patient assessment.
- Continuously assess the effectiveness and safety of prophylactic measures, adjusting as needed based on patient response and any emerging risk factors.
Management
- Score ≥2:
- The patient is at increased risk for VTE.
- Start appropriate pharmacologic (e.g., low molecular weight heparin) or mechanical (e.g., compression stockings, intermittent pneumatic compression) prophylaxis.
- Score <2:
- The patient is at low risk for VTE.
- Pharmacologic thrombophylaxis is not warranted.
- Early ambulation with or without mechanical prophylaxis may be appropriate.
- If pharmacologic prophylaxis is warranted, evaluate for and weigh the risk of bleeding. Consider combining this assessment with the IMPROVE Bleeding Risk Score.
