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)
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)
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)
OBJECTIVE To update the Mortality Probability Model at intensive care unit (ICU) admission (MPM0-II) using contemporary data. DESIGN Retrospective analysis of data from 124,855 patients admitted to 135 ICUs at 98 hospitals participating in Project IMPACT between 2001 and 2004. Independent variables considered were 15 MPM0-II variables, time before ICU(More)
OBJECTIVE To determine if trauma patients qualifying by a 1990 American College of Surgeons (ACS) audit filter have the same outcomes and resource utilizations as similar (matching) patients not qualifying by the filter. DESIGN Retrospective, case control study. MATERIALS AND METHODS Data for 21,175 patients submitted during 1992 to the Pennsylvania(More)
