The literature review that follows incorporates the characterisation of trauma centres, an overview of the nature and severity of injuries and a description of the TRISS method of analysing injury severity.
Age as an important determinant of human physiological reserve and hence patient survival, is discussed with the TRISS method of analysing injury severity.
The TRISS method gives a physiological and anatomical index of injury severity based on the Injury Severity Score (ISS), the Revised Trauma Score (RTS), the patient's age and whether the injury was blunt or penetrating (Woodford, 2001:5).
In combining these four parameters, the TRISS method is useful to quantify the probability of survival (Ps) and to evaluate the outcomes of trauma care.
assess the severity of injuries, according to the TRISS method, on admission to the trauma casualty; and
To determine the injury severity index, a sample of 10% (n=163) was randomly selected for analysis using the TRISS method.
In order to apply the TRISS method of analysing injury severity (Table 2), the sample was categorised into blunt trauma (n=52) and penetrating trauma (n=111).
Researchers and trauma practitioners generally agree that the TRISS method is one of the major advances in measuring injury severity and trauma outcomes.
