Abstract
We investigated the difference of severity between belted and unbelted patients in several types of collisions in our emergency room. In frontal collision, mortality and the severity of whole body were significantly higher in unbelted than in belted. In near-side collision, mortality and the severity of head/neck, face were significantly higher in unbelted than in belted. In far-side collision, mortality and the severity of head/neck, face, chest were significantly higher in unbelted than in belted. In rear end collision, the severity of chest was significantly higher in unbelted than in belted. Seatbelt use was effective in all types of collisions to prevent severe injury.
