REHABIL-AID: a three-year project titled “Reducing the harm and the burden of injuries and human loss caused by road traffic crashes and addressing injury demands through effective interventions” carried out in Greece, Germany and Italy with funding by the DG Mobility and Transport (MOVE/C4/SUB/2011-294/SI2.628846/REHABIL-AID). The project involves a multicenter longitudinal study aiming to assess the psycho-socio-economic costs of RTCs for severely injured people and identify factors that affect the rehabilitation process, one year after the injury. The study involves collection of data from adult patients, hospitalized in intensive care units of selected hospitals in the three participating countries, with injuries sustained in RTC. The results of the study will be used to develop interventions and tools tailored to the needs of the injured people such as recommendations on the care of the severely injured, a map of rehabilitation services and a map of the care pathway following RTCs.
