Introduction
Discussion
In 1974, Baker have found the degree of injury to classify trauma victims based on the severity of the injury known as the Injury Severity Score (ISS), which is based on the value of the Abbreviated Injury Scale (AIS), which had the wound by scoring the severity of anatomy [6] parameter ISS scores highly correlate with the probability of survival of the traumatized patient. The ISS uses six different regions of the head and neck, face, chest, abdomen or pelvic contents, extremities, and external structures. ISS scoring with description are minor, moderate; severe, not life-threatening; severe, life-threatening; critical, survival uncertain; un survivable [7].
The weakness of ISS if there is severe multiple injury to one body region and the ISS gives equal weight to each body region, for example: AIS 3 score in the chest region will give a different prognosis when compared with AIS 3 score in the head region. Other examples: AIS 5 score in the chest region will provide a different prognosis when compared to the AIS score of 5 in the head region [7] In 1997, to improve the limitations of ISS was found New Injury Severity Score (NISS) which sums the quadrants of the three injuries that have the most AIS scores higher regardless of whether it comes from a different region [8].
The difference between the ISS is that NISS sees only the degree of severity of the injury to account for the different multiple surfaces in one region of the body. In addition, there are scores of injury degrees based on a combination of physiological and anatomical parameters which have two well-known first Trauma Related Injury Severity Score (TRISS) and International Classification of Disease, 9th revision, Injury Severity Score (ICISS) [5].
An injury severity assessment method is important to predict the outcome of an injury. Differences in criteria used for assessment of injury are necessary because they are associated with possible mortality, cost, reliability, quality of life, and disability. Methods used include ICISS (ICD-based Injury Severity Score) which involves the value of Survival Risk Ratio (SRR) which calculates the life expectancy ratio for individual (ratio of the number of patients with surviving injury code compared to the total number of patients who has been diagnosed with the code). The ICISS score comes from ICD-10-AM which contains code due to injuries suffered [9] ICSS is also combined with the age and score of Revised Trauma Score (RTS) in an analytical approach is similar to Trauma Related Injury Severity Score (TRISS) analysis. This method has a superior and better prediction compared to TRISS.10 The ICISS scoring method was introduced by Rutledge et al and claimed to provide a better prediction of trauma outcome than the TRISS scoring method with the application of the neural network information system. Limitations of ICISS methods are:
-
a) Recording of deaths occurring only in hospitals.
b) Limitations in identifying patients.
c) Affected by SRR value.
d) Excluded from the diagnosis of injury (co morbid factor).
e) Some studies have found that ICISS values have the same values as SRR when compared to the SRR value ratio to obtain ICISS values.
