The injury severity score: a method for describing patients with multiple injuries and evaluating emergency care

Abstract: A method for comparing death rates of groups of injured persons was developed, using hospital and medical examiner data for more than two thousand persons. The first step was determination of the extent to which injury severity as rated by the Abbreviated Injury Scale correlates with patient survival. Substantial correlation was demonstrated. Controlling for severity of the primary injury made it possible to measure the effect on mortality of additional injuries. Injuries that in themselves would not normally be life-threatening were shown to have a marked effect on mortality when they occurred in combination with other injuries. An Injury Severity Score was developed that correlates well with survival and provides a numerical description of the overall severity of injury for patients with multiple trauma. Results of this investigation indicate that the Injury Severity Score represents an important step in solving the problem of summarizing injury severity, especially in patients with multiple trauma.

1974 AMA-SAE-AAAM revision of the Abbreviated Injury Scale (AIS)

Abstract: Usage of the AIS since 1969 revealed a need to refine the overall AIS rating, to examine mathematical methods for determining the overall injury rating, to eliminate AIS codes based on death, to develop a body-region listing and a comprehensive alphabetized listing, and to revise and reclassify a few codings. An ad hoc committee was appointed to perform these tasks. One significant change in the AIS, dropping of the "fatal" codes, is discussed, along with several minor changes. A definition and discussion of the overall AIS is presented. The Injury Severity Score (ISS) is proposed as a possible means of computing the overall rating, but continued use of the AIS is recommended for the immediate future. A listing of the AIS by body regions is included, as well as a comprehensive alphabetized listing, developed by the American Medical Association, of injury diagnoses.
