Methods: This retrospective study was conducted at a tertiary care center between January 1 and December 31, 2022. Adult patients admitted to the ED with multiple trauma and subsequently transferred to the ICU were included. Demographic characteristics, trauma mechanisms, laboratory values, and ICU outcomes were recorded. The predictive value of GPR for ICU mortality was analyzed using receiver operating characteristic (ROC) curve analysis. Additional comparisons were made with established biomarkers such as lactate and injury severity score (ISS). Results: A total of 253 patients met the inclusion criteria. The most common trauma mechanisms were falls (45.7%) and traffic accidents (38.9%). Median GPR was significantly higher in non-survivors than in survivors [45.5 (30.5–63.6) vs. 31.6 (25.8-39.5), p=0.001]. ROC analysis yielded an area under the curve (AUC) of 0.712 for GPR. The optimal cut-off value was 66.9, with a sensitivity of 21% and specificity of 95%. In logistic regression analysis, GPR was identified as an independent predictor of mortality (p=0.004, Exp (B): 0.96). While lactate (AUC: 0.775) and ISS (AUC: 0.881) showed stronger predictive power, GPR remains a practical and accessible marker in the ED setting. Conclusion: GPR is a simple, rapid, and cost-effective biomarker that may contribute to early risk stratification in multiple trauma patients. Although it should not be used in isolation for clinical decision-making, it may serve as a valuable adjunct to established prognostic tools. Further prospective and multicenter studies are warranted to validate its clinical utility.}, number={5}, publisher={MediHealth Academy Yayıncılık}, organization={Yok}
