Summary

More than a decade before the publication of this text, leaders at the National Institute of Neurological Disorders and Stroke (NINDS) of the National Institutes of Health (NIH) in Bethesda, Maryland, judged that research might be better coordinated, and efforts of different teams of investigators far better synthesized, if scholars used a common toolbox of outcome measures. The importance of that judgment is apparent to anyone who has undertaken a meta-analysis only to find that 100 experiments seeking to test the same scientific hypothesis were all done in unique and incomparable ways. The initiative to rectify this problem by strongly recommending specific instruments was christened the Common Data Elements (CDE) project. The authors of the present chapter have been intimately engaged in this progressive initiative. Here, they expertly summarize the first major product released by that team: the CDEs for traumatic brain injury. This is half the battle toward capitalizing on the collective efforts of researchers around the nation and the world, all working to understand CBI. The other half of the battle, of course, is to define CBI biologically.
