The Padua Prediction Score is a risk assessment model used to determine the risk of Venous Thromboembolism (VTE) in hospitalized medical patients. It helps clinicians decide whether thromboprophylaxis (preventative treatment for blood clots) is indicated.
How It Works
The calculator sums up points based on specific clinical risk factors. Each factor is weighted according to its impact on VTE risk:
High Impact (3 points): Active cancer, history of VTE, reduced mobility, or thrombophilic conditions.
Moderate Impact (2 points): Recent trauma or surgery within the last month.
Standard Impact (1 point): Age over 70, heart/respiratory failure, acute MI/stroke, infection, obesity, or hormonal treatment.
Interpretation of Results
The total score categorizes a patient into one of two risk groups:
Score < 4 (Low Risk): The risk of VTE is considered low. Typically, pharmacological prophylaxis is not indicated unless specific clinical judgment suggests otherwise.
Score ≥ 4 (High Risk): The risk of VTE is considered high. Thromboprophylaxis is generally recommended for these patients to prevent clotting complications.
