What this trial studies

This observational study aims to assess the incidence and prevalence of intracranial bleeding events associated with oral anticoagulant therapy, including vitamin K antagonists and factor Xa and 2a inhibitors. It will analyze clinical records of patients diagnosed with intracranial hemorrhage while on anticoagulant therapy from January 2015 to July 2023. The study will also explore mortality rates related to these bleeding events and identify patient characteristics and treatment patterns associated with anticoagulant-related intracranial hemorrhages.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old who have been diagnosed with intracranial hemorrhage while receiving oral anticoagulant therapy.

Not a fit: Patients without available clinical records or those who did not complete follow-up after an intracranial bleeding event may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve understanding of the risks associated with anticoagulant therapy, potentially leading to better management strategies for patients at risk of intracranial bleeding.

How similar studies have performed: Other studies have shown success in understanding the risks of anticoagulant therapy, making this approach relevant and potentially impactful.
