Padua Prediction Score Calculator

The Padua Prediction Score Calculator estimates VTE risk based on age, BMI, and specific medical history. This tool helps healthcare professionals quickly assess patients to prevent dangerous blood clots. Whether you are admitting a patient or conducting daily rounds, this calculator provides a validated score to guide thromboprophylaxis decisions.

Patient's age in years (0-120)
BMI in kg/m² (10-50)
Patient has active cancer (3 points)
Previous venous thromboembolism (3 points)
Reduced mobility (3 points)
Known thrombophilic condition (3 points)
Recent trauma or surgery within 1 month (2 points)
Heart and/or respiratory failure (1 point)
Acute MI or ischemic stroke (1 point)
Acute infection and/or rheumatologic disorder (1 point)
Ongoing hormonal treatment (1 point)

How Padua Prediction Score Is Calculated

The Padua Prediction Score is a point-based system used to gauge the likelihood of venous thromboembolism in medical patients. It assigns different weights to risk factors, acknowledging that some conditions pose a greater threat than others.

Padua Score = Sum of Risk Factor Points

Key Risk Factors:

  • 3 Points: Active cancer, previous VTE, reduced mobility, known thrombophilic condition
  • 2 Points: Recent trauma or surgery (≤1 month)
  • 1 Point: Age ≥70, BMI ≥30, heart/respiratory failure, acute MI/stroke, acute infection/rheumatologic disorder, ongoing hormonal treatment

First, evaluate the patient’s age and Body Mass Index (BMI). Then, identify high-impact medical conditions such as reduced mobility or previous blood clots. Finally, add up the points for all present factors. This validated method ensures a standardized approach to risk assessment across different patients.

What Your Padua Prediction Score Means

This score categorizes a patient's risk level to help you make crucial treatment decisions quickly. A total score helps determine if the patient needs medication to prevent clots.

High-Risk Patients

Scores of 4 or higher indicate a significantly increased danger of blood clots, with a risk rate around 11%. In these cases, medical guidelines strongly suggest starting pharmacological thromboprophylaxis unless there is a specific bleeding risk.

Low-Risk Patients

For patients scoring under 4, the risk is much lower, and routine blood thinners are generally not recommended. However, mechanical methods might be considered for some individuals based on clinical judgment.

It is vital to remember that this score is a screening tool only and does not replace a full clinical evaluation by a qualified healthcare provider. Always use your professional judgment when deciding on treatment plans.

You should reassess the patient if their condition changes or after major procedures during their hospital stay.
