The Injury Severity Score (ISS) has limited predictive power and is difficult to calculate. We used the New Injury Severity Score (NISS) and compared it to the ISS. The purpose of this study was to give a prognosis and predict the mortality for trauma patients by using the ISS and the NISS and to compare Trauma and Injury Severity Score (TRISS) method using NISS with the TRISS method using ISS.
A retrospective study of 100 trauma victims who visited the emergency room of Kyungpook National University Hospital from September 2000 to May 2001 was made using the ISS, the NISS, and the TRISS methods.
A comparison between survivors and nonsurvivors showed differences in the revised trauma score (RTS), ISS, NISS, and TRISS Ps-1 by using RTS and the ISS and TRISS Ps-2 by using RTS and NISS (p<0.01). We found that the NISS was more predictive of survival than the ISS. A receiver operating curve analysis and Hosmer Lemeshow statistics showed that both the NISS and the ISS provided a good fit throughout its entire range of prediction.
By comparing the ISS with the NISS, we concluded that the NISS better separated survivors from nonsurvivors. The NISS predicted survival better and was easier to calculate than the ISS. The results of the TRISS method using NISS were satisfactory, and we expect to use this method in quality assessment with further study and modification.
