Evaluation of trauma care must be an integral part of any system designed for care of seriously injured patients. However, outcome review should offer comparability to national standards or norms. The TRISS method offers a standard approach for evaluating outcome of trauma care. Anatomic, physiologic, and age characteristics are used to quantify probability(More)
The Trauma Score (TS) has been revised. The revision includes Glasgow Coma Scale (GCS), systolic blood pressure (SBP), and respiratory rate (RR) and excludes capillary refill and respiratory expansion, which were difficult to assess in the field. Two versions of the revised score have been developed, one for triage (T-RTS) and another for use in outcome(More)
The Major Trauma Outcome Study (MTOS) is a retrospective descriptive study of injury severity and outcome coordinated through the American College of Surgeons' Committee on Trauma. From 1982 through 1987, 139 North American hospitals submitted demographic, etiologic, injury severity, and outcome data for 80,544 trauma patients. Motor vehicle related(More)
OBJECTIVE In 1986, data from 25,000 major trauma outcome study patients were used to relate Trauma and Injury Severity Score (TRISS) values to survival probability. The resulting norms have been widely used. Motivated by TRISS limitations, A Severity Characterization of Trauma (ASCOT) was introduced in 1990. The objective of this study was to evaluate and(More)
A three-valued description of anatomic injury is presented. Anatomic profile (AP) components A, B, and C summarize serious injuries (greater than AIS 2) to the head/brain or spinal cord; to the thorax or front of the neck; and all remaining serious injuries. Relationships between AP components and survival rate reaffirm the seriousness of head injury.(More)
The types and severity of injuries of 49,143 patients from 95 trauma centers were coded according to the 1985 version of the Abbreviated Injury Scale (AIS). This paper analyzes the causes, incidence, and mortality in 16,524 patients (33.6% of the trauma center patients) with injury to the brain or skull and compares them to patients without head injury.(More)
ASCOT (A Severity Characterization of Trauma) is a physiologic and anatomic characterization of injury severity which combines emergency department admission values of Glasgow Coma Scale, systolic blood pressure, respiratory rate, patient age, and AIS-85 anatomic injury scores in a way that obviates ISS shortcomings. ASCOT values are related to survival(More)
We computed regression coefficients for TRISS analysis for all 4271 pediatric patients (aged 1 through 14 years) with complete data from the Major Trauma Outcome Study. We then compared predicted pediatric and adult TRISS survival probability norms. There were no statistically significant differences in the predicted and actual numbers of survivors using(More)
