Office of Biomedical Translational Research Informatics

The Biomedical Translational Research Information System (BTRIS) is a resource available to the NIH intramural community that brings together clinical research data from the Clinical Center and other NIH Institutes and Centers. BTRIS provides clinical investigators with access to identifiable data for subjects on their own active protocols, while providing all NIH investigators with access to data without personal identifiers across all protocols. Data are available from 1976 to the present.

BTRIS Functions

Active Protocols

Active Protocols

Active Protocol Data is available to NIH intramural research team members associated with a protocol.


Hypotheis Generation

Hypothesis Generation allows NIH intramural researchers to access clinical research data without personal identifiers from the NIH Clinical Center systems from 1976 to the present. View a    Limited Data Set Query video (disclaimer) for additional details.

Subject Attribution

Subject Attribution

Subject Attribution is managed through a custom application called Preferences. Users can confirm the association of a subject with an active protocol, or set thresholds for notifications and permissions related to secondary data use.

Clinical Trial Reporting

Clinical Trials Reporting allows NIH intramural researchers to assemble and format data required for FDAAA compliance. Once filing materials are complete in BTRIS, the user may automatically upload the file to
