This study analyzes the impact of pre-existing conditions as a new indicator of injury and fatality risk in automobile accidents. Using CISS data (2017-2022, 9,889 cases), statistical analysis was conducted using chi-square tests and t-tests. The results show that individuals with pre-existing conditions have a 6.7 times higher risk of severe injury and a 3.4 times higher risk of fatality even in minor collisions. These findings suggest that future safety technologies should evolve beyond energy absorption strategies and incorporate occupant-specific safety measures.
