Discriminant Ability of the Shock Index, Modified Shock Index, and Reverse Shock Index Multiplied by the Glasgow Coma Scale on Mortality in Adult Trauma Patients: A PATOS Study

We evaluated a cohort of adult trauma patients transported to emergency departments. The first vital signs were used to calculate the SI, MSI, and rSIG. The areas under the receiver operating characteristic curves (AUROCs) and test results were used to compare the discriminant performance of the indices on short-term mortality and poor functional outcome. A subgroup analysis of geriatric patients, traumatic brain injury, penetrating injury, and non-penetrating injury was performed.
