  "abstract": "Background and importance\n\nEarly trauma-induced coagulopathy (eTIC) is a major contributor to hemorrhage-related mortality after severe trauma. Viscoelastic testing using thromboelastography (TEG) has been increasingly implemented in trauma resuscitation; however, its prognostic value compared with conventional coagulation testing remains uncertain.Objectives\n\nWe evaluated the ability of TEG parameters to detect eTIC, hypofibrinogenemia, and hyperfibrinolysis in severely injured trauma patients. In addition, we assessed their prognostic performance for transfusion requirements and mortality compared with conventional laboratory parameters.Design\n\nRetrospective single-center cohort study.Settings and participants\n\nSeverely injured adult trauma patients admitted to the resuscitation room of a Level I trauma center, between January 2019 and October 2024 were screened.Outcome measures and analysis\n\nPrimary outcomes were detection of eTIC (INR > 1.2), severe coagulopathy (INR > 1.5), hypofibrinogenemia (< 200 mg/dL), and thrombocytopenia (< 100,000/μL). Secondary outcomes included the ability of coagulation parameters to predict the need for transfusion of ≥ 5 units of packed red blood cells within the first 24 h after admission and in-hospital mortality.Results\n\nA total of 262 patients were included; median ISS was 29 (IQR 23-41), and in-hospital mortality was 22.8%. eTIC was present in 31.5% of patients. TEG parameters showed moderate discriminatory performance for coagulopathy detection. For eTIC, maximum amplitude achieved an AUC of 0.73, while R-time achieved an AUC of 0.65. Predictive performance improved for severe coagulopathy, with R-time reaching an AUC of 0.81. Hyperfibrinolysis (LY30 > 7%) was uncommon (6.9%). Conventional laboratory parameters, particularly INR, consistently outperformed TEG-derived parameters for prediction of transfusion requirements (AUC 0.85) and mortality (AUC 0.79).Conclusion\n\nIn severely injured trauma patients, conventional coagulation testing, particularly INR, demonstrated superior prognostic performance compared with individual TEG parameters. Viscoelastic testing may provide complementary information but did not replace standard laboratory testing for prediction of transfusion needs or mortality in this cohort.Trial registration\n\nClinicalTrials.gov identifier: NCT07186712.",
