Usefulness of Shock Index to Predict Outcomes of Trauma Patient: A Retrospective Cohort Study

ABSTRACT

PURPOSE@#We investigated how prehospital, emergency room (ER), and delta shock indices (SI) correlate with outcomes including mortality in patients with polytrauma.@*METHODS@#We retrospectively reviewed the medical records of 1,275 patients who visited the emergency department from January 2015 to April 2018. A total of 628 patients were enrolled in the study. Patients were divided into survivor and non-survivor groups, and logistic regression analysis was used to investigate independent risk factors for death. Pearson coefficient analysis and chi-square test were used to examine the significant relationship between SI and clinical progression markers.@*RESULTS@#Of 628 enrolled patients, 608 survived and 27 died. Multivariate logistic regression analysis reveals “age” (p0.9” (p0.9) were associated with poor clinical progression.@*CONCLUSIONS@#SI and delta SI are significant predictors of mortality in patients with polytrauma. Moreover, both prehospital and ER SIs can be used as predictive markers of clinical progression in these patients.
