7.3. Polytraumatic Injuries Requiring Specialized Rehab
Recent combat has resulted in new patterns of polytraumatic injuries and disability requiring specialized intensive rehabilitation processes and coordination of care throughout the course of recovery and rehabilitation. While serving in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF), military service members are sustaining multiple severe injuries as a result of explosions and blasts. Improvised explosive devices, blasts, landmines, and fragments account for 65 percent of combat injuries (see subpar. 17a). Congress recognized this newly emerging pattern of military injuries with the passage of Public Law 108-422, Section 302, and Public Law 108-447.
Combat injuries are often the result of a blast. Blasts cause injuries through multiple mechanisms. Severe blasts can result in total body disruptions and death to those closest to the blast site or they can result in burns and inhalation injuries. Blast injuries typically are divided into four categories: primary, secondary, tertiary, and quaternary or miscellaneous injuries.
1. Primary Blast Injuries. Primary blast injuries are caused by overpressure to gas- containing organ systems, with most frequent injury to the lung, bowel, and inner ear (tympanic membrane rupture). These exposures may result in traumatic limb or partial limb amputation.
2. Secondary Blast Injuries. Secondary blast injuries occur via fragments and other missiles, which can cause head injuries and soft tissue trauma.
3. Tertiary Blast injuries. Tertiary Blast injuries result from displacement of the whole body by combined pressure loads (shock wave and dynamic overpressure).
4. Miscellaneous Blast-related Injuries. These are miscellaneous blast-related injuries such as burns and crush injuries from collapsed structures and displaced heavy objects. Soft tissue injuries, fractures, and amputations are common.
Animal models of blast injury have demonstrated damaged brain tissue and consequent cognitive deficits. Indeed, the limited data available suggests that brain injuries are a common occurrence from blast injuries and often go undiagnosed and untreated as attention is focused on more "visible" injuries. A significant number of casualties sustain emotional shock and may develop PTSD. Individuals may sustain multiple injuries from one or more of these mechanisms. Explosions can produce unique patterns of injury seldom seen outside combat.
Center for Disease Control and Prevention (CDC) Classification of Blast Injuries

Traumatic amputation, fractures, crush injuries, burns, cuts, lacerations, infections, acute arterial occlusion, air embolism-induced injury.
Crush injuries, burns, infections, slow healing wounds.
Emotional or Psychological
Acute stress reactions, PTSD, survivor guilt, post-concussion syndrome, depression, generalized anxiety disorder.
Acute pain from wounds, crush injuries, or traumatic amputations; chronic pain syndromes.
Recognizing the specialized clinical care needs of individuals sustaining multiple severe injuries, VA has established four PRCs. The PRC mission is to provide comprehensive inpatient rehabilitation services for individuals with complex physical, cognitive and mental health sequelae of severe and disabling trauma, to provide medical and surgical support for ongoing and/or new conditions, and to provide support to their families. Intensive clinical and social work case management services are essential to coordinate the complex components of care for polytrauma patients and their families. Coordination of rehabilitation services must occur seamlessly as the patient moves from acute hospitalization through acute rehabilitation and ultimately back to the patient's home community. Transition to the home community may include a transfer from a PRC to a less acute facility.
The Secretary of Veterans Affairs designated five PRCs, co-located with TBI Lead Centers, at VA Medical Centers in Richmond, VA; Tampa, FL; Minneapolis, MN; San Antonio, TX, and Palo Alto, CA (see App. A). It is VHA policy that the PRCs provide a full-range of care for all patients eligible for VA care, who have sustained varied patterns of severe and disabling injuries including, but not limited to: TBI, amputation, visual and hearing impairment, spinal cord injury (SCI), musculoskeletal injuries, wounds, and psychological trauma. Due to the medical complexity of these patients, PRCs must be prepared to admit individuals who may have a higher level of medical acuity and require interdisciplinary management by various medical specialists. The general admission criteria to the PRC include:
1.The individual with polytrauma is an eligible veteran or an active duty military service member; and
2.The individual has sustained multiple physical, cognitive, and/or emotional impairments secondary to trauma; and
3.The individual has the potential to benefit from inpatient rehabilitation; or
4.The individual has the potential to benefit from a transitional community re-entry program; or
5.The individual requires an initial comprehensive rehabilitation evaluation and care plan.
It is recommended that all patients experiencing a polytraumatic injury be referred to a VA PRC. The PRC team has specialized expertise to determine the most appropriate setting for care. If the patient does not require admission to a PRC, the team can assist with coordination of care at the most appropriate facility. Referral to a PRC also ensures that the patient and family are integrated into the VA system of care with the appropriate rehabilitation services. NOTE: The SCI Chief for the applicable region needs to be contacted by the PRC admissions clinical case manager to consult on the transfer of patients with a diagnosis of TBI and SCI.
Referrals to the PRC must be given the highest priority and the screening process needs to be expedited to ensure that there are no delays in transferring a patient to the Center. The PRC must accept admissions on a 24/7 basis. To establish the medical needs and acuity of the patient, there is a need to review medical documentation, consult with the referring treatment provider, and coordinate a plan for transfer.
Referral of service members with polytrauma to a PRC is initiated by DOD, typically by the MTF social worker or case manager, or other DOD representative. Where assigned, the VA- DOD liaison social worker is actively involved in the referral process, facilitating communications, information exchange, transition of care, and family support. The PRC's admissions clinical case manager coordinates the referral and screening process for the accepting VA PRC. NOTE: For those referral sources that do not have VA-DOD liaisons, admission screening is to be coordinated between the PRC admission clinical case manager and the MTF.
Points of Contact
VA Polytrauma Points of Contact are available at 39 VAMCs without specialized rehabilitation teams. These Points of Contact, established in 2007, are knowledgeable about the VA Polytrauma/TBI System of care and coordinate case management and referrals throughout the system and may provide a more limited range of rehabilitation services. See a full list of Polytrauma Points of Contact in the attached PDF.
