Improving decision-making for managing unprovoked venous thromboembolism
Official title: Prognosis Improvement of Unprovoked vEnous THromboEmbolism With the Use of a Shared Decision-making Process Including a Time-dependent Multicomponent Risk Prediction Scores inteRvention.
Run by University Hospital, Brest · NCT06731244 · Data updated 2026-11-12
This study is testing a new way to help patients with unprovoked blood clots decide how long to take blood thinners, to see if it leads to better health outcomes.

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.
