Low Risk<4High Risk4+

Padua Score 0: Low risk - routine pharmacological prophylaxis is not recommended.

  • A score below 4 places this patient in the low-risk category. The observed VTE rate was 0.3% in this group.
  • Mechanical prophylaxis (graduated compression stockings or intermittent pneumatic compression) may still be appropriate based on clinical judgment.
  • Reassess the Padua Score if the patient's condition changes during admission.

Next stepRecalculate if clinical status changes (e.g., new infection, extended immobility, or surgery).
