Formula:
The Padua Prediction Score is determined by summing points assigned to various risk factors for venous thromboembolism (VTE). Each contributing factor is weighted with a specific number of points:
- Active cancer: 3 points
- Previous VTE (excluding superficial vein thrombosis): 3 points
- Reduced mobility (strict bed rest ≥3 days or chairfast due to paralysis, paresis, or plaster cast): 3 points
- Known thrombophilic condition: 3 points
- Recent trauma and/or fracture (within 1 month): 2 points
- Recent surgery (within 1 month): 2 points
- Elderly (≥70 years): 1 point
- Heart and/or respiratory failure (NYHA class III/IV, LVEF < 40%, severe COPD): 1 point
- Obesity (BMI ≥30 kg/m²): 1 point
- Acute infection and/or rheumatologic disease (at least 1 week): 1 point
Total Padua Score = Sum of all applicable points.
Interpretation:
- < 4 points: Low risk of VTE
- ≥ 4 points: High risk of VTE (thromboprophylaxis is generally recommended)
