Injury rating is an important issue in the field of traffic safety. The injury pattern can be obtained either from the scene of the accident, including all severity grades, or from the frequency of those fatally injured. Less attention has been paid to the long-term consequences of an injury. Furthermore, the existing rating system is based on the medical status at the scene of the accident or immediately after and judges only the risk of death.Nygren showed that for many body regions the AIS values did not reflect the outcome of a trauma expressed in permanent medical disability.In this study, 339,675 accidents with private cars were analyzed with respect to injuries to car occupants. In these accidents, 14,361 persons were injured. The risk of permanent disability due to different injuries is derived and linked to AIS values to different body regions.A rating system for injuries based on the risk of death or permanent disability is proposed. The rating system called RSC, risk of serious consequences, used ISS and AIS for different body regions. RSC was used to describe differences in injuries to belted and unbelted car occupants.
