Submit a request

ACR welcomes requests for analysis using data from NRDR. Applications for data use will be accepted from a wide variety of requestors including registry participants, nonregistry participants, industry and governmental organizations.

To ensure the dissemination of high-quality evidence and the stewardship of registry data, NRDR research requests are reviewed by a registry specific Data Request Review Panel composed of members from the individual registry committees and NRDR staff and guided by the NRDR Steering Committee Chair.

Registry data are not provided for off-site analysis. For approved applications, an ACR data analyst works with the requestor(s) to fulfill the data request.

Persons requesting data will be notified about the approval status of their request within one to three months, depending on the complexity of the data request. Approved requests are prioritized across all registry data analysis requests, and an NRDR data analyst will notify you when work is about to begin on your request.
