Patient Registries


Patient registries are databases where patient information, including medical information and family history, is collected and stored in a standardized and secure way. Most often the aggregated data is used for medical research, epidemiologic or other research studies. Registries can be used to recruit patients for clinical trials to learn about a particular disease or condition; to develop therapeutics or to learn about population behavior patterns and their association with disease development; developing research hypotheses; or for improving and monitoring the quality of health care.


Global Rare Diseases (Patient) Registry and Data Repository (GRDR)

The Office of Rare Diseases Research (ORDR) held the Advancing Rare Disease Research: The Intersection of Patient Registries, Biospecimen Repositories, and Clinical Data workshop in January, 2010 to discuss the concept and the development of an internet-based, federated rare disease registry. Following the workshop, ORDR launched the Global Rare Diseases Patient Registry and Data Repository (GRDR) to collect de-identified patient information from rare disease patient registries and to assist patient groups with no registry to establish their disease registries.

A Request for Information (RFI) was released on February 10, 2012 requesting information from patient groups about their interest in participating in a GRDR pilot project.

Common Data Elements (CDEs)

Use of common data elements (CDEs) facilitates the standardization of data entry and allows for harmonization, sharing, and exchange of information across registries and diseases, and facilitates various analyses and studies of specific rare diseases. ORDR established a CDE committee to develop a set of minimal CDEs for patient data entry to be used in any rare disease registry. These CDEs will facilitate the use and analysis of aggregated data in a meaningful way. Future steps will include the development of CDEs for organ system involvement in rare diseases and rare disease-specific CDEs to facilitate data entry/reporting by clinicians, other health care professionals, and researchers. All future recommended CDEs will be established in collaboration with the various NIH Institutes and Centers and other professional and patient organizations that have already developed related CDEs or are in the process of developing them.

Informed Consent

One of the challenges in obtaining patient consent, including participating in a patient registry, is ensuring that participants receive all the information and background material necessary to make a fully informed decision and understand what they are agreeing to. The signing of the consent helps protect and inform participants and investigators about how participants’ data and samples may be used.  In December, 2010, ORDR sponsored the Informed Consent Models/Templates for Rare Disease Registries linked to Biorepositories meeting.  Based on input from this meeting, ORDR has published recommendations for patient consent when participating in registries that are associated with biorepositories.  In addition, to assist the rare disease community, the ORDR has developed a template for an informed consent form for participating in a patient registry. This template can be modified according to the specific needs of each registry.

Rare Diseases Human Biorepositories/Biospecimen ( RD-HUB)

Biospecimens are an essential resource for studying the pathogenesis of disease and for other biomedical research.  ORDR encourages patient registries to have biospecimens collected that can be linked to the patient medical information (using a Voluntary Unique Patient Identifier) and to list those collections in the RD-HUB.The RD-HUB is a searchable database indicating the availability of biospecimens for research to facilitate collaboration around the globe.
