Trauma center intervention is the rate-limiting step that will decide the degree of functional recovery of persons with brain injuries. If these persons are to attain maximal functional recovery, then there must be a system of intensive, organized care that begins at the scene of the trauma and continues until disposition from the trauma center either to home or an acute rehabilitation hospital. The success of this system of care within a trauma center is dependent on five disciplines: prehospital care, emergency medicine, trauma teams or services, critical care medicine, and rehabilitation medicine.
