What this trial studies

This observational study collects data on patients who are starting or switching to anticoagulant treatments, including vitamin K antagonists and novel direct oral anticoagulants. It aims to evaluate the efficacy and safety of various anticoagulant therapies and improve understanding of their risks and benefits. Patients aged 18 and older are included if they are beginning anticoagulation therapy or switching from one type of anticoagulant to another, with a minimum expected treatment duration of three months. The study is designed to gather comprehensive clinical histories and treatment patterns over at least one year.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are starting anticoagulant therapy or switching from vitamin K antagonists to other anticoagulants.

Not a fit: Patients under 18 years old or those unwilling to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of anticoagulant therapies, leading to improved treatment strategies for patients with conditions like atrial fibrillation and venous thromboembolism.

How similar studies have performed: Other observational studies have successfully gathered data on anticoagulant therapies, indicating that this approach is supported by previous research.
