The predictive value of the modified early warning score with rapid lactate level (ViEWS-L) for mortality in patients of age 65 or older visiting the emergency department

Abstract

The purpose of this study is to detect the predictive power of the modified early warning score with rapid lactate level (ViEWS-L) on mortality in critical patients over the age of 65 years admitted to the emergency department (ED). A total of 616 non-traumatic patients admitted to the Uludag University Faculty of Medicine ED who were 65 years of age or older were included in this study (Ethics board number: 2015-4/8). In this prospective study; the ViEWS-L score of the patients were calculated. The results have been evaluated with rate of mortality in the first 24 h starting from submission. The area under the ROC curve was found 0.872 and the cut-off value to detect mortality was found 10.83 for the ViEWS-L score. In the model obtained by the univariate binary logistic regression analysis, ViEWS-L score was found statistically significant and it was determined that mortality risk increased 1.286 times for each unit increase in the score of ViEWS-L score. As a result of this research, it was found that ViEWS-L scoring system is effective in determining the mortality of 65 years and older patients.
