The National Institutes of Health's Biomedical Translational Research Information System (BTRIS): design, contents, functionality and experience to date.

The US National Institutes of Health (NIH) has developed the Biomedical Translational Research Information System (BTRIS) to support researchers' access to translational and clinical data. BTRIS includes a data repository, a set of programs for loading data from NIH electronic health records and research data management systems, an ontology for coding the disparate data with a single terminology, and a set of user interface tools that provide access to identified data from individual research studies and data across all studies from which individually identifiable data have been removed. This paper reports on unique design elements of the system, progress to date and user experience after five years of development and operation.

Developing a self-service query interface for re-using de-identified electronic health record data.

The US National Institutes of Health has developed a repository of clinical research data drawn in part from electronic health records. A new de-identified data query tool under development has been developed to support re-use of these data. We used a collection of 30 human-mediated user queries to determine whether features of the tool will be sufficient to allow users to carry out the queries themselves.

The clinical research data repository of the US National Institutes of Health.

The US National Institutes of Health (NIH) includes 27 institutes and centers, many of which conduct clinical research. Previously, data collected in research trials has existed in multiple, disparate databases. This paper describes the design, implementation and experience to date with the Biomedical Translational Research Information System (BTRIS), being developed at NIH to consolidate clinical research data.
