Definition of the American College of Surgeon’s Committee on Trauma (ACSCOT): aundertriage = major trauma (ISS more than 15) admitted to trauma center level III; bovertriage = not severe trauma (ISS less than 16) admitted to trauma center level I or II.
Definition of the Northern French Alps Trauma System (TRENAU): cundertriage = major trauma (ISS more than 15) admitted initially to a level III trauma center before a transfer to a level I or II; or death in a trauma center level III; dovertriage = not severe trauma (ISS less than 16) admitted to emergency room with an activation of trauma team in a level I or II trauma center. ARR: absolute risk reduction; CI: confidence interval; ISS, injury severity score; RR: relative risk.
