Serum Levels of Copeptin Predict Adverse Outcomes and Improve Risk Prediction of TRISS and MGAP Scores in Patients with Polytrauma: A Single Center Prospective Cohort Study.

Admission serum copeptin levels were correlated with clinical severity in polytrauma. Coupling copeptin with pre-existing trauma severity scores improved prediction accuracy. Copeptin shows promise as a novel biomarker for the prediction of trauma outcome.
