What is the NIH CDE Repository?
The National Institutes of Health (NIH) defines a common data element (CDE) as "standardized, precisely defined questions paired with a set of specific allowable responses, used systematically across different sites, studies, or clinical trials to ensure consistent data collection." Using CDEs in health research improves data collection accuracy and consistency across studies. The National Library of Medicine and the NIH recently made improving data interoperability in health research a strategic priority by recommending, and often requiring, the use of CDEs in the studies they support. In 2015, the NIH developed the NIH CDE Repository to make it easier for the health research community to utilize CDEs in their research
