Padua Score Calculator
Assess VTE risk in hospitalized patients and determine prophylaxis recommendations
VTE Risk Assessment
Select all risk factors that apply to the patient. The Padua score helps determine whether pharmacological VTE prophylaxis is recommended for hospitalized patients.
Assessment Results
Clinical Assessment: Low risk for venous thromboembolism. Mechanical prophylaxis may be sufficient.
Pharmacological Options:
- •Pharmacological prophylaxis not indicated
- •Focus on mechanical methods
- •Reassess if clinical condition changes
Mechanical Prophylaxis:
- •Compression stockings
- •Intermittent pneumatic compression devices
- •Early ambulation when possible
- •Calf exercises ("pumping")
⚠️ Important Clinical Considerations
Threshold: Score ≥4 indicates high VTE risk requiring pharmacological prophylaxis
Contraindications: Always consider bleeding risk before starting anticoagulation
Reassessment: Re-evaluate daily as patient condition and risk factors may change
Mechanical prophylaxis: Should be used regardless of pharmacological prophylaxis decision
Example Case
Clinical Scenario
Patient: 75-year-old female admitted for pneumonia
Risk Factors:
- • Age ≥70 years (1 point)
- • Reduced mobility due to illness (3 points)
- • Acute infection (1 point)
Total Score: 5 points
Assessment: High risk - pharmacological prophylaxis recommended
Padua Score Interpretation
Scores ≥4 indicate high VTE risk and recommendation for pharmacological prophylaxis
VTE Manifestations
Deep Vein Thrombosis (DVT)
Blood clot in deep veins, usually legs
Pulmonary Embolism (PE)
Clot travels to block lung arteries
Other VTE
CVST, Budd-Chiari syndrome, portal vein thrombosis

Understanding the Padua Score
What is VTE?
Venous thromboembolism (VTE) is a condition where blood clots form in veins and can travel to block blood flow. It's a major cause of morbidity and mortality in hospitalized patients.
Why Use the Padua Score?
- •Validated risk assessment tool for hospitalized patients
- •Helps identify patients who benefit from prophylaxis
- •Reduces unnecessary anticoagulation in low-risk patients
- •Standardizes VTE risk assessment across healthcare teams
Risk Factor Categories
High-Impact Factors (3 points)
- • Reduced mobility
- • Active cancer
- • Previous VTE history
- • Known thrombophilic condition
Moderate-Impact Factors (2 points)
- • Recent trauma or surgery
Low-Impact Factors (1 point)
- • Age ≥70 years
- • Obesity (BMI ≥30)
- • Hormonal treatment
- • Heart/respiratory failure
- • MI/stroke
- • Acute infection/rheumatologic disease
