Abstract

Introduction: Application of simple assessments and measurements has allowed trauma to be quantified and compared by means of various scoring systems, e.g. AIS, ISS, NISS, RTS and TRISS. Probability of survival is affected by the ISS and the NISS scores and its calculation is dependant on these variables. Both the ISS and the NISS have been shown to predict probability of survival to varying degrees in different studies. The aim of our study was to assess how the NISS compared with the ISS in predicting the probability of survival.
Method: A retrospective study was carried out and the ISS and NISS scores of 550 trauma patients were calculated with all other required parameters. The probability of Survival was then calculated for every patient using both the ISS and the NISS score. The relationship between the Probability of survival with the ISS and the NISS was assessed using the correlation analysis.
Result: ISS had a mean of 10.22 and the NISS had a mean of 13.45 in our trauma patient population. The results showed strong negative correlations between ISS and Ps with an r-value of -0.63 (p lt 0.005) and between NISS and Ps with an r-value of -0.70 (p lt 0.005). The strength of the relationship between NISS and Ps was greater than that between ISS and Ps.
