Abstract

The main goal of the NIH/NCATS GRDR® program is to serve as a central web-based global data repository to integrate de-identified patient clinical data from rare disease registries, and other data sources, in a standardized manner, to be available to researchers for conducting various biomedical studies, including clinical trials and to support analyses within and across diseases. The aim of the program is to advance research for many rare diseases. One of the first tasks toward achieving this goal was the development of a set of Common Data Elements (CDEs), which are controlled terminologies that represent collected data. A list of 75 CDEs was developed by a national committee and was validated and implemented during a period of 2 year proof of concept. Access to GRDR CDEs is freely available at: https://grdr.ncats.nih.gov/index.php?option=com_content&view=article&id=3&Itemid=5. The GRDR CDEs have been the cornerstone of the GRDR repository, as well as of several other national and international patient registries. The establishment of the GRDR program has elevated the issue of data standardization and interoperability for rare disease patient registries, to international attention, resulting in a global dialog and significant change in the mindset of registry developers, patient advocacy groups, and other national and international organizations.
