Trends in Department of Defense Disability Evaluation System Ratings and Awards for Posttraumatic Stress Disorder and Traumatic Brain Injury, 2002–2017
May 10, 2021
U.S. Department of Defense (DoD) policies for medically evaluating service members have changed considerably since 2001, with major changes to the disability evaluation system beginning in 2007. Simultaneously, DoD also implemented new policies in response to the "signature injuries" of the wars in Iraq and Afghanistan: posttraumatic stress disorder and traumatic brain injury. The authors review these concurrent developments.
For almost two decades, the United States has been engaged in continuous combat operations in Iraq, Afghanistan, and other theaters. Some service members have sustained injuries or developed medical conditions as a consequence of military service that affect their ability to perform their military duties.
The process by which the U.S. Department of Defense (DoD) evaluates service members and determines whether they should be medically discharged has changed considerably since 2001. In particular, beginning in 2007, major changes to the Disability Evaluation System (DES) were implemented in response to concern about inefficiencies and confusion resulting from the practice of having DoD and the U.S. Department of Veterans Affairs (VA) conduct separate evaluations according to different criteria, thus producing different disability determinations.
In 2008, DoD launched a pilot program to streamline the disability evaluation process, with VA conducting medical exams to be used by both DoD and VA. This system, the Integrated Disability Evaluation System (IDES), was formally adopted military-wide in 2011. Changes to DES also reflected changes in understanding of traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD), the signature injuries of the Iraq and Afghanistan wars. The authors review changes to disability evaluation policy and changes in the diagnosis and treatment of PTSD and TBI since 2001.
