The Trauma Scores, CRAMS scales, and mechanisms of injury of 500 trauma patients were evaluated for their ability to identify a seriously injured patient. Serious injury was defined as one of the following: Injury Severity Score (ISS) greater than 15, or emergency-room Trauma Score less than or equal to 14, or injuries requiring greater than 3 days hospitalization, or death. ⋯ With these same mechanisms, the sensitivity of a CRAMS scale of less than or equal to 8 increased from 66% to 93%, with a specificity of 30%. The addition of these mechanisms of injury to standard field triage scoring appears to improve the identification of seriously injured patients while retaining an acceptable level of overtriage.

AbstractThe Trauma Scores, CRAMS scales, and mechanisms of injury of 500 trauma patients were evaluated for their ability to identify a seriously injured patient. Serious injury was defined as one of the following: Injury Severity Score (ISS) greater than 15, or emergency-room Trauma Score less than or equal to 14, or injuries requiring greater than 3 days hospitalization, or death. With the addition of specific mechanisms of injury (auto vs. pedestrian accident at greater than 5 m.p.h., motor vehicle accident at greater than 40 m.p.h., motorcycle accident at greater than 20 m.p.h., or a major assault), the sensitivity of a field Trauma Score of less than 14 could be improved from 45% to 75%, with a reasonable specificity of 40%. With these same mechanisms, the sensitivity of a CRAMS scale of less than or equal to 8 increased from 66% to 93%, with a specificity of 30%. The addition of these mechanisms of injury to standard field triage scoring appears to improve the identification of seriously injured patients while retaining an acceptable level of overtriage.
