What this trial studies

The ATHNdataset is an observational registry that securely collects and regularly updates clinical, laboratory, genetic, imaging, treatment, and patient-reported data from individuals seen at ATHN-affiliated Hemophilia Treatment Centers. Participants of any age who can consent or have a legally authorized representative agree to have their health records and surveys entered into a central database. The registry captures detailed information such as bleed events, medications, surgeries, pharmacokinetic results, and quality-of-life measures and is maintained over time to reflect current health status. Aggregated and de-identified data are made available to clinicians, researchers, and policymakers to study real-world outcomes and inform care and policy decisions.

Who should consider this trial

Good fit: Ideal candidates are people of any age who have or are being evaluated for a bleeding or clotting disorder, have an encounter at an ATHN-affiliated center, and can provide consent or have a legally authorized representative provide consent.

Not a fit: People who do not receive care at ATHN-affiliated centers or who cannot provide consent are unlikely to be enrolled and therefore will not directly benefit from the registry's data.

Why it matters

Potential benefit: If successful, the registry could reveal real-world patterns of bleeding, treatment responses, and quality-of-life that help shape better treatments, guidelines, and policies for people with blood disorders.

How similar studies have performed: Similar large observational registries in hemophilia and sickle cell disease have previously produced useful real-world evidence that influenced treatment guidelines and policy.
