Escala de Trauma Nuevo como predictor de mortalidad en pacientes politraumatizados del Hospital Teodoro Maldonado Carbo-IESS, período 2015-2020.

Abstract

Trauma is one of the leading causes of mortality worldwide. Major trauma severity scales aid in decision-making related to patient care, however the plethora of scales indicate that there is a need for a universal system. The objective of this study was to determine the usefulness of the NTS (New Trauma Score) as a predictor of mortality in multiple trauma patients, identifying its validity through the Hosmer and Lemeshow test and its discrimination capacity through the development of the ROC curve and parameters of sensitivity, specificity, positive and negative predictive values, based on data from multiple trauma patients, admitted to the Teodoro Maldonado Carbo Specialties Hospital, during the period 2015-2020. The NTS showed its validity by reaching a significance of 0.429, confirming that it would obtain the same expected death values in reality. Likewise, it tested its discrimination capacity, with values of 0.949 in the area under the curve, with a cut-off point of 17, as the best for mortality risk screening, since it has sensitivity and NPV values (negative predictive value) of 100%. Although it is true, there is no broad superiority against other scales, its importance lies in recognizing that those have subjectivity and difficulty in taking certain parameters, compared to the NTS that uses parameters that are easy to record.
