We plan to begin the subject evaluation in October 2021. The objective of this evaluation is to determine the extent to which the Defense Health Agency (DHA) and Military Service medical departments implemented policies and procedures, and provided oversight, to ensure that Service members who sustained a Traumatic Brain Injury (TBI) were identified and screened to determine their appropriate level of care. In addition, we will determine the extent to which the U.S. Central Command (USCENTCOM) Service Components screened, identified, and documented signs and symptoms of TBIs. We may revise the objective as the evaluation proceeds, and we will consider suggestions from management for additional or revised objectives.
