Rating the Severity of Tissue Damage: II. The Comprehensive Scale

JAMA. 1972;220(5):717-720. doi:10.1001/jama.1972.03200050055013

The previously published AMA Abbreviated Injury Scale1 provides what most motor vehicle collision investigators need for minimum scientific injury evaluation—an accurate, uniform, and acceptable means for such evaluation. However, a small group of investigators who met in Detroit in 1968 to discuss means of improving injury scaling techniques, as well as a larger group sponsored by the American Medical Association in 1969, realized that scientific investigation teams require a more comprehensive and sophisticated scale. Therefore, a new system of rating the severity of tissue damage was planned which would include the Abbreviated Injury Scale, a Comprehensive Injury Scale, and a CrossReferenced Comprehensive Index.

Limitations of the Abbreviated Injury Scale  The major limitation of the Abbreviated Injury Scale is that the various criteria used in rating injuries cannot readily be identified and separated. Automotive engineers are primarily interested in energy dissipation, or the amount of force required to produce a
