Affiliated Registries

How to become one and which affiliated registries are there?

EuRR-Bone and EuRRECa aim to be inclusive registries rather then competing. Therefore we signpost health care providers and patients to other high quality detailed disease registries on topics not covered by our projects.

Why should an existing registry consider to become affiliated registry?

  • Our information sheets and consent forms can be used for the affiliate registry as well as the Core Registry
  • Data entered in the Core Registry can be shared with the affiliate registry
  • Greater visibility of the affiliate registry through EuRRECa’s/EuRR-Bones channels of dissemination
  • Greater likelihood of sustaining high quality detailed disease registries
  • Opportunities to exchange experiences on the activities and sharing methodological tools for improving the registry quality
