Frequently asked questions

What is the Padua Prediction Score?

A risk assessment model for venous thromboembolism in hospitalized medical patients. Score ≥ 4 identifies high-risk patients who benefit from pharmacologic prophylaxis.

Padua vs Caprini?

Padua is for medical inpatients; Caprini is for surgical patients. Both are recommended in respective populations by ACCP guidelines.

What prophylaxis is indicated at Padua ≥ 4?

LMWH (e.g., enoxaparin 40 mg SC daily), UFH 5 000 U SC q8–12h, or fondaparinux — duration typically until discharge.

When is Padua not applicable?

Patients with active bleeding, recent intracranial hemorrhage, or other absolute contraindications to anticoagulation — use mechanical prophylaxis instead.
