TRACK-TBI Pilot

TRACK-TBI Pilot was a multi-center observational pilot study aimed to validate the feasibility of implementing the TBI Common Data Elements (TBI-CDEs). A total of 586 subjects who underwent computed tomography (CT) scans in the emergency department within 24 h of injury were enrolled at three level I trauma centers (San Francisco General Hospital, University of Pittsburgh Medical Center, University Medical Center Brackenridge) and one rehabilitation center (Mount Sinai Rehabilitation Center). The TBI-CDE components collected included: 1) demographic, social and clinical data; 2) biospecimens from blood drawn for genetic and proteomic biomarker analyses; 3) neuroimaging studies at 2 weeks using 3T MRI; and 4) outcome assessments at 3 and 6 months.

Data from the TRACK-TBI Pilot is publically available and can be downloaded from the FITBIR website.
