Committee on the Assessment of Ongoing Efforts in the Treatment of Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is one of the signature injuries of the U.S. conflicts in Afghanistan and Iraq, but it affects veterans of all eras. It is estimated that 7-20% of service members and veterans who served in Operation Enduring Freedom and Operation Iraqi Freedom may have the disorder. PTSD is characterized by a combination of mental health symptoms - re-experiencing of a traumatic event, avoidance of trauma-associated stimuli, adverse alterations in thoughts and mood, and hyperarousal - that last at least 1 month and impair functioning. PTSD can be lifelong and pervade all aspects of a service member's or veteran's life, including mental and physical health, family and social relationships, and employment. It is often concurrent with other health problems, such as depression, traumatic brain injury, chronic pain, substance abuse disorder, and intimate partner violence. The Department of Defense (DoD) and the Department of Veterans Affairs (VA) provide a spectrum of programs and services to screen for, diagnose, treat for, and rehabilitate service members and veterans who have or are at risk for PTSD. The 2010 National Defense Authorization Act asked the Institute of Medicine to assess those PTSD programs and services in two phases. The Phase 1 study, Treatment for Posttraumatic Stress Disorder in Military and Veteran Populations: Initial Assessment, focused on data gathering. Treatment for Posttraumatic Stress Disorder in Military and Veteran Populations Final Assessment is the report of the second phase of the study. This report analyzes the data received in Phase 1 specifically to determine the rates of success for each program or method. Treatment for Posttraumatic Stress Disorder in Military and Veteran Populations Final Assessment considers what a successful PTSD management system is and whether and how such a system is being implemented by DoD and VA. This includes an assessment of what care is given and to whom, how effectiveness is measured, what types of mental health care providers are available, what influences whether a service member or veteran seeks care, and what are the costs associated with that care. This report focuses on the opportunities and challenges that DoD and VA face in developing, implementing, and evaluating services and programs in the context of achieving a high-performing system to care for service members and veterans who have PTSD. The report also identifies where gaps or new emphases might be addressed to improve prevention of, screening for, diagnosis of, and treatment and rehabilitation for the disorder. The findings and recommendations of Treatment for Posttraumatic Stress Disorder in Military and Veteran Populations: Final Assessment will encourage DoD and VA to increase their efforts in moving toward a high-performing, comprehensive, integrated PTSD management strategy that addresses the needs of current and future service members, veterans, and their families.

Final Assessment

Treatment for Posttraumatic Stress Disorder in Military and Veteran Populations

Prior to the military conflicts in Iraq and Afghanistan, wars and conflicts have been characterized by such injuries as infectious diseases and catastrophic gunshot wounds. However, the signature injuries sustained by United States military personnel in these most recent conflicts are blast wounds and the psychiatric consequences to combat, particularly posttraumatic stress disorder (PTSD), which affects an estimated 13 to 20 percent of U.S. service members who have fought in Iraq or Afghanistan since 2001. PTSD is triggered by a specific traumatic event - including combat - which leads to symptoms such as persistent re-experiencing of the event; emotional numbing or avoidance of thoughts, feelings, conversations, or places associated with the trauma; and hyperarousal, such as exaggerated startle responses or difficulty concentrating. As the U.S. reduces its military involvement in the Middle East, the Departments of Defense (DoD) and Veterans Affairs (VA) anticipate that increasing numbers of returning veterans will need PTSD services. As a result, Congress asked the DoD, in consultation with the VA, to sponsor an IOM study to assess both departments' PTSD treatment programs and services. Treatment for Posttraumatic Stress Disorder in Military and Veteran Populations: Initial Assessment is the first of two mandated reports examines some of the available programs to prevent, diagnose, treat, and rehabilitate those who have PTSD and encourages further research that can help to improve PTSD care.
