Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have had a first episode of symptomatic unprovoked pulmonary embolism or proximal deep vein thrombosis treated with anticoagulants for 3 to 6 months.

Probably not a fit

Patients with isolated distal DVT, isolated sub-segmental PE, or those with previous unprovoked VTE may not benefit from this study.

What this trial studies

This study focuses on enhancing the management of unprovoked venous thromboembolism (VTE) through a shared decision-making process. It involves patients who have experienced a first episode of symptomatic unprovoked pulmonary embolism or proximal deep vein thrombosis and have been treated with anticoagulants for 3 to 6 months. The study compares usual care with a structured decision-making approach to determine the optimal duration of anticoagulant therapy, addressing the significant risks associated with both VTE and anticoagulation. The goal is to improve patient outcomes by tailoring treatment duration based on individual circumstances.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective management of anticoagulant therapy, reducing risks of recurrence and bleeding for patients.

How similar studies have gone: Other studies have explored shared decision-making in healthcare, indicating potential for success, but this specific approach for unprovoked VTE management is relatively novel.
