Common Data Elements (CDE)

The National Institutes of Health (NIH) encourages the development and use of common data elements (CDE) for clinical research, patient registries, and other human subject research in order to improve data quality and opportunities for comparison and combination of data from multiple studies and with electronic health records.

The Common Data Elements portal provides a single source for National Institute on Drug Abuse Clinical Trials Network-recommended CDEs of Substance Use Disorders for use in clinical trials and electronic health records.
