Introduction: Trauma is an important area of research, as it tends to take away a heavy toll of life regularly. To compare the severity and clinical outcome for the trauma patients, a number of injury severity scores have been designed as standardised tools. Although several systems exist, there is no consensus on, which is the best for predicting mortality.
Aim: To correlate various clinico-radiological parameters of the trauma patients and their trauma scores i.e., Revised Trauma Score (RTS) and New Injury Severity Score (NISS) and their outcome with respect to survival accordingly.
Materials and Methods: Sixty-one patients were randomly included in this study after taking informed written consent from the patients above 18 years of age and well oriented to time, place, and person or from such guardians if the patients were less than 18 years. Patients were then subjected to a fixed trauma protocol regularly followed at the study institute and trauma scoring was done for each one of them. The statistical analysis was done using statistical software SPSS for Windows (version 16), chi-square test was used for non parametric variable, Student’s t-test was used for comparing two groups and one way ANOVA test was used for multiple groups’ comparisons. p-value <0.05 was stated as statistically significant. ROC curve was used as a tool for diagnostic test evaluation.
Results: Out of 61 patients, RTS at presentation of survived patients were 7.2504±0.73178 and the patients who died were 6.09990±1.23611 with a p-value of 0.014 and sensitivity as 85%. NISS at presentation of survived patients was 17.39±6.614 and for the patients who died were 26.29±4.990 with a p-value being <0.001 and sensitivity being 100%.
Conclusion: New Injury Severity Score is a more sensitive scoring system and a better outcome predictor in comparison to RTS system.
