About the Padua score calculator
The Padua Prediction Score is a clinical risk assessment model for venous thromboembolism in hospitalized adult medical patients. Venous thromboembolism, or VTE, includes deep vein thrombosis and pulmonary embolism. The score helps identify patients whose combination of acute illness, immobility, history, and other factors places them at increased risk during hospitalization. It was developed for medical inpatients and is not automatically applicable to surgical, obstetric, pediatric, or outpatient populations.
Four major factors receive three points each: active cancer, previous VTE other than superficial vein thrombosis, reduced mobility for at least three days, and known thrombophilia. Recent trauma or surgery within about one month receives two points. Age 70 or older, heart or respiratory failure, acute myocardial infarction or ischemic stroke, acute infection or rheumatologic disorder, obesity with BMI at least 30, and ongoing hormonal treatment each receive one point. The applicable values are added without further weighting.
A total below 4 is categorized as low VTE risk, while a score of 4 or more is categorized as high risk. The threshold supports structured decisions about thromboprophylaxis, but it does not prescribe treatment by itself. Pharmacologic prophylaxis may be inappropriate when active bleeding, severe thrombocytopenia, a high bleeding risk, or another contraindication is present. Mechanical measures, medicine choice, dose, and duration depend on clinical circumstances and current institutional guidance.
Accurate scoring requires careful definitions and timing. Reduced mobility refers to substantial restriction rather than simply being admitted to a bed. Cancer activity, prior events, thrombophilia, recent procedures, and acute conditions should be confirmed from the history and record. Risk can change during a hospital stay, so reassessment may be appropriate when mobility worsens, a new diagnosis appears, or treatment changes. The score should be documented with the selected factors rather than as a number alone.
This calculator is intended for trained healthcare use and education. It does not assess bleeding risk, diagnose a clot, or replace examination and local protocols. Symptoms such as sudden shortness of breath, chest pain, unilateral leg swelling, or unexplained deterioration require immediate clinical evaluation regardless of score. Apply current evidence-based guidelines and professional judgment when deciding on prophylaxis. Used correctly, the Padua score provides a transparent checklist that can reduce missed risk factors and improve consistency in inpatient VTE prevention conversations.

Padua score calculator FAQ
Who is the Padua score designed for?
It was validated for hospitalized adult medical patients. Different tools or protocols may be appropriate for surgical, obstetric, pediatric, or ambulatory patients.
What Padua score indicates high VTE risk?
A total of 4 or more indicates high risk in the validated model. Scores below 4 are classified as low risk.
Which factors carry the most points?
Active cancer, previous VTE, reduced mobility, and known thrombophilia each carry three points. These major factors can move a patient close to or beyond the high-risk threshold individually.
Does a high score automatically mean anticoagulation?
No, treatment decisions also require assessment of bleeding risk, contraindications, patient preferences, and current guidelines. The score supports but does not replace clinical judgment.
Should the Padua score be recalculated?
Reassessment can be appropriate when mobility, diagnoses, or treatments change during hospitalization. Documenting the underlying factors makes later review more reliable.
