Comparison of Trauma Scores for Adults Who Fell From Height as Survival Predictivity

Abstract

Aim: Falls from a height and their subsequent injuries and traumas can cause morbidity and death. In the present study, ISS, NISS, RTS, and TRISS values were analyzed to assess mortality probabilities of patients who fell from a height. Materials and Methods: Patients' age, gender, height of falls (0-2 m, 3-5 m, and 6 m and above), organ pathologies, and ISS, NISS, RTS, and TRISS scores were evaluated in terms of mortality. Results: Regarding the survival rate, no statistically significant difference was found between age and gender (P > 0.05). We determined that all trauma scores were correlated with mortality, and that as Injury Severity Score (ISS), New Injury Severity Score (NISS), and Trauma and Injury Severity Score (TRISS) values increased, and as Revised Trauma Score (RTS) values decreased, the mortality rate tended to increase. The area under the curve in the Receiver Operating Characteristic (ROC) analysis was 0.991 for TRISS, 0.910 for ISS, and 0.915 for NISS (P > 0.001). The most satisfactory cut-off point for TRISS was 73.5 and at that point, we found the best sensitivity, specificity, and positive and negative predictive values. Conclusions: In conclusion, the data showed that TRISS values can be used with high reliability when this value is over 73.5 and any score above it has high specificity and mortality.
