AUSNBled
Bleeding disorders of unknown cause
AUSNBled is a voluntary register of individuals with bleeding disorders of unknown cause (BDUC). The purpose of the registry is to investigate and improve the long-term clinical care and treatment of individuals with bleeding disorders.
The registry collects general demographic information, bleeding and treatment history, and, where possible, available medical and diagnostic information from treating health professionals.
These data are utilised to support ongoing research with the aim to improve our understanding of treatment options and outcomes. Participants contribute valuable insights that may lead to advancements in the diagnosis, management, and care of bleeding disorders.
