Padua Prediction Score
Clinical Recommendation
About Venous Thromboembolism Risk Assessment
🩺 What is the Padua Score?
The Padua Prediction Score is a validated risk assessment model designed to identify hospitalized medical patients at high risk for venous thromboembolism (VTE). It helps clinicians determine which patients would benefit from pharmacological prophylaxis during hospitalization.
⚕️ Clinical Application
This score is specifically designed for hospitalized medical patients and should not be used for surgical patients or those already on anticoagulation. The score helps standardize VTE risk assessment and prophylaxis decisions across different healthcare settings.
📊 Score Interpretation
- Score ≥4: High VTE risk – Consider pharmacological prophylaxis
- Score <4: Low VTE risk – Prophylaxis generally not recommended
- Sensitivity: 96% for identifying high-risk patients
- Specificity: 35% for identifying low-risk patients
🔬 VTE Pathophysiology
VTE encompasses both deep vein thrombosis (DVT) and pulmonary embolism (PE). Risk factors align with Virchow’s triad: venous stasis, endothelial injury, and hypercoagulability. Hospitalized patients face increased risk due to immobility, inflammation, and underlying medical conditions.
💊 Prophylaxis Options
- Pharmacological: Low molecular weight heparin, unfractionated heparin, or direct oral anticoagulants
- Mechanical: Graduated compression stockings, intermittent pneumatic compression
- Early mobilization: Encourage ambulation when medically appropriate
⚠️ Important Considerations
This calculator is for educational purposes and should not replace clinical judgment. Always consider individual patient factors, bleeding risk, contraindications to anticoagulation, and institutional guidelines when making prophylaxis decisions. Consult current clinical guidelines and specialist recommendations when appropriate.
