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.

Problems in the management of type III (severe) open fractures: a new classification of type III open fractures

Abstract: Between 1976-1979, 87 Type III open fractures (in 75 patients) were treated at the Hennepin County Medical Center. Factors leading to increased morbidity in Type III fractures were: massive soft-tissue damage; compromised vascularity; severe wound contamination; and marked fracture instability. This study demonstrates, because of varied severity and prognosis, that the current designation of Type III open fracture is too inclusive. We recommend, therefore, that Type III open fractures be divided, in order of worsening prognosis, into three subtypes. Type IIIA--Adequate soft-tissue coverage of a fractured bone despite extensive soft-tissue laceration or flaps, or high-energy trauma irrespective of the size of the wound. Type IIIB--Extensive soft-tissue injury loss with periosteal stripping and bone exposure. This is usually associated with massive contamination. Type IIIC--Open fracture associated with arterial injury requiring repair. Wound sepsis in the three subtypes were: Type IIIA, 4%, IIIB, 52%; and IIIC, 42%; while amputation rates were, respectively, 0%, 16%, and 42%. Only two patients developed osteomyelitis, and 12 patients had delayed or nonunions. Five patients died, all as a result of multisystem trauma. The bacterial pathogens in infected open fractures have changed dramatically over the years. In the present series (1976-1979), 77% of infections were due to Gram-negative bacteria, compared with 24% previously (1961-1975). A change of antibiotic therapy from a first-generation cephalosporin alone to a combination of a cephalosporin and an aminoglycoside, or a third-generation cephalosporin, is currently indicated in Type III open fractures.

Evaluating trauma care: the triss method. trauma score and the injury severity score

Abstract: 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 of survival as related to severity of injury. TRISS offers a means of case identification for quality assurance review on a local basis, as well as a means of comparison of outcome for different populations of trauma patients. Methods for calculating statistics associated with TRISS are presented. The Z and M statistics are explained with the nonstatistician in mind. We feel this article is a source for those interested in developing or upgrading trauma care evaluation.

The role of secondary brain injury in determining outcome from severe head injury.

Abstract: As triage and resuscitation protocols evolve, it is critical to determine the major extracranial variables influencing outcome in the setting of severe head injury. We prospectively studied the outcome from severe head injury (GCS score < or = 8) in 717 cases in the Traumatic Coma Data Bank. We investigated the impact on outcome of hypotension (SBP < 90 mm Hg) and hypoxia (Pao2 < or = 60 mm Hg or apnea or cyanosis in the field) as secondary brain insults, occurring from injury through resuscitation. Hypoxia and hypotension were independently associated with significant increases in morbidity and mortality from severe head injury. Hypotension was profoundly detrimental, occurring in 34.6% of these patients and associated with a 150% increase in mortality. The increased morbidity and mortality related to severe trauma to an extracranial organ system appeared primarily attributable to associated hypotension. Improvements in trauma care delivery over the past decade have not markedly altered the adverse influence of hypotension. Hypoxia and hypotension are common and detrimental secondary brain insults. Hypotension, particularly, is a major determinant of outcome from severe head injury. Resuscitation protocols for brain injured patients should assiduously avoid hypovolemic shock on an absolute basis.

A revision of the Trauma Score.

Abstract: 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 evaluations and to control for injury severity (RTS). T-RTS, the sum of coded values of GCS, SBP, and RR, demonstrated increased sensitivity and some loss in specificity when compared with a triage criterion based on TS and GCS values. T-RTS correctly identified more than 97% of nonsurvivors as requiring trauma center care. The T-RTS triage criterion does not require summing of the coded values and is more easily implemented than the TS criterion. RTS is a weighted sum of coded variable values. The RTS demonstrated substantially improved reliability in outcome predictions compared to the TS. The RTS also yielded more accurate outcome predictions for patients with serious head injuries than the TS.
