The effectiveness of shock indices on prognosis in burn patients admitted to the emergency department

Shock index (SI) is the ratio of heart rate (HR) to systolic blood pressure (SBP); modified SI (MSI) is the ratio of HR to mean arterial pressure; age SI (ASI) is age multiplied by SI; reverse SI (rSI) is the ratio of SBP to HR; and rSIG is rSI multiplied by Glasgow Coma Scale Score (rSIG). Studies have proven that shock indices are good tools in predicting mortality. This study aimed to evaluate the sensitivity of the shock indices SI, MSI, ASI, rSI, and rSIG in predicting mortality in burn patients. This is a retrospective cross-sectional study. The vital signs of the patients were recorded and their shock indices were calculated at the time of emergency department admission. The effectiveness of the shock indices SI, MSI, ASI, rSI, and rSIG in predict-ing mortality was compared in the burn patients included in the study RESULTS: A total of 913 patients were enrolled. rSIG and MSI were the shock indices with the highest area under the curve (AUC) values in predicting mortality in the burn patients. The AUC values of rSIG and MSI were 0.829 (95% CI: 0.739-0.919, P
