Joseph Giacino, PhD, Michael McCrea, PhD, and Murray Stein, MD MPH co-lead the Outcomes Core (OC). The OC leads are supported by Lindsay Nelson, PhD. The Outcomes Core is responsible for design, collection, and evaluation of measures to capture study outcomes. Under their supervision, the OC will also review outcomes data quality in conjunction with the BC. The OC will oversee site training for collection of the various outcomes, and the OC, CC, and ICON will collaboratively manage protocol oversight. Protocols and training procedures will be adapted from the existing TRACK-TBI Manual of Operations and Procedures.
