Federal Interagency Traumatic Brain Injury Research (FITBIR) Matthew J. McAuliffe, PhD Co-director FITBIR Chief, Biomedical Imaging Research Services Section (BIRSS) email: Matthew.McAuliffe@nih.gov (301) 594-2432
Challenges 1. Research Small sample size Studies of the same subject at multiple locations Lack of detailed visibility in all available TBI research Unable to easily validate other s results 2. Data accessibility Data takes months/years to get into papers/journals Data is typically summarized and rarely complete Data acquired not using CDEs Data lost after grant ends
FITBIR The FITBIR is a collaborative biomedical informatics system to support research in Traumatic Brain Injury to accelerate scientific discovery and treatment FITBIR mission goals: 1. Promotion for the sharing of quality research data throughout the TBI research community a. Attribution for shared data b. Timing of sharing data c. Access model 2. Definition of standards to enable cross site meta-analysis and data comparisons (i.e. NINDS TBI CDEs, GUID) 3. Central repository and portal for phenotypic, genomic, and imaging data. 4. Deployment of useful tools for community adoption
