Padua Score Calculator

Our Padua score calculator checks on the most essential venous thromboembolism (VTE) risk factors of your patient and informs you whether the use of the pharmacological prophylaxis is necessary.

Our tool will not only compute the Padua prediction score, but thanks to the article included below, you'll be able to find out more about the DVT prophylaxis guidelines and VTE risk assessment process.

We try our best to make our Omni Calculators as precise and reliable as possible. However, this tool can never replace a professional doctor's assessment. If any health condition bothers you, consult a physician.

VTE stands for the venous thromboembolism. It is a group of diseases of different manifestations and complications that share a common origin: the famous triad of Virchow and the hypercoagulation defect.

1. VTE usually begins from the episode of the venous thrombosis (a blood clot forming in one of the veins), which may take the form of:

   • DVT - deep vein thrombosis

     The most common type, characterized by a swollen, warm, painful limb.

   • CVST- cerebral venous sinus thrombosis

     Rare type of stroke - often diagnosed in pregnant/postpartum women.

   • Budd-Chiari syndrome thrombosis of the hepatic vein

     May result in liver insufficiency.

2. The formed and detached clot, then called embolus, may travel further into the cardiovascular system, blocking other veins/arteries. That may result in:

   • 📍 Pulmonary embolism - blockage of one of the lungs arteries.

     The symptoms vary from shortness of breath to sudden death.

   • 📍 Paradoxical embolism - blockage of one of the brain arteries, resulting in a stroke.

This situation is only possible in people with defects in heart structure, e.g., in atrial septum.

Different medical facilities may use their own VTE/DVT risk scores, developed in their own clinical surroundings. However, a group of recommended tools may further facilitate the decision if the pharmacological prophylaxis' gains outweigh the possible side effects.

Your diagnostic process should start with the least invasive methods, such as measuring D-dimers, and checking for the signs and symptoms of the DVT (usually present in lower limbs). You may also perform ultrasound compression testing - probe pressed against an affected vessel will reveal a formed thrombus.

There are two well-known tools for pulmonary embolism:

• Revised Geneva score calculator
• Wells score calculator

They both focus on age, presence of the DVT, reduced mobility, and concomitant diseases.

We may also enumerate two other famous VTE risk score calculators:

• Padua score
• Caprini score

You may also check the patient's coagulability state and the risk of bleeding, using PT and INR tests, HAS-BLED calculator and the CHA₂DS₂-VASC score stratification. 💉

Venous thromboembolism prophylaxis comprises of both pharmacological and mechanical methods.

Mechanical:

• Compression stockings;
• Intermittent pneumatic compression devices;
• Calf exercise, "pumping"; and
• Early ambulation after surgery.

Pharmacological: (anticoagulation) 💊

• Low molecular weight heparin (LMWH), or unfractionated heparin (UFH);
• Vitamin K antagonists , e.g. warfarin;
• Direct oral anticoagulants (DOACs).

The use of pharmacological prophylaxis doesn't exclude the use of the mechanical one!

Our Padua score calculator uses the following equation:

Padua score = Age + Obesity + Reduced mobility + Hormonal treatment+ Active cancer + Trauma/surgery + Previous VTE + Thrombophilic condition + Failure + Myocardial infraction + Infection

The enumerated variables take the following values:
