Abstract

Objectives: This study was conducted to evaluate two simple and quickly assessed parameters such as shock index (SI) and lactate to predict in-hospital mortality in multi-trauma patients admitted to the emergency department (ED).
Material and Methods: The study included a total of 93 patients who presented to the ED with multitrauma. In our retrospective study, SI was calculated by taking blood pressure and pulse values from the files of the patients recorded at the time of admission to the ED, and lactate values obtained from blood gas were recorded. The results were compared with the in-hospital mortality rates after admission. SI (p<0.001) and lactate (p<0.001) values in patients discharged as exitus were significantly higher (p<0.05). The predictive diagnostic value of SI and lactate levels in terms of mortality in the patients included in the study was analyzed by using ROC curve analysis.
Results: The area under the ROC curve for SI was 0.738. The SI cut-off value for patients’ mortality findings was 1.14. The area under the ROC curve for the lactate value was 0.941. The lactate cut-off value for mortality findings was 4.5.
Conclusion: In conclusion, SI and lactate values obtained at ED admission can be used to predict mortality in multitrauma patients.
