What this trial studies

This observational study aims to create a nationwide cohort of patients diagnosed with venous thromboembolism (VTE) to understand which individuals should receive long-term anticoagulation therapy. It will involve yearly follow-ups through various methods such as telephone, hospitalization, or outpatient care. The study will collect comprehensive data, including demographic, clinical, imaging, laboratory, and genetic information, to develop a risk prediction model for VTE recurrence. This model will help clinicians make informed decisions regarding the duration of anticoagulant therapy based on individual risk levels.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have been diagnosed with venous thromboembolism.

Not a fit: Patients who are pregnant, lactating, or have an active tumor may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective management of anticoagulation therapy for patients with venous thromboembolism.

How similar studies have performed: Other studies have shown success in developing risk stratification models for VTE, but this specific nationwide cohort approach may provide novel insights.
