Abstract

Objectives: To investigate the prognostic value for mortality of the admission        serum glucose-to-potassium ratio in patients with severe traumatic brain injury (TBI). Methods: A retrospective, prospective, cross-sectional descriptive study, with follow-up of the outcomes, was conducted on 103 patients with severe traumatic brain injury treated at the Surgical Intensive Care Unit, Military Hospital 103, from December 2021 to September 2025 and were followed for mortality outcomes.Results: The majority of patients (69.9%) were of working age (21 - 59 years old), predominantly male (81.6%), with traffic accidents being the primary cause of injury (75.73%). The mortality group had significantly lower Glasgow coma scale (GCS) scores but higher Marshall and Rotterdam scores, and higher glucose/potassium ratios than the survival group (p < 0.05). The area under the curve for the glucose-to-potassium ratio in predicting mortality was 0.71. The multivariate logistic regression model based on heart rate and GCS score helps improve prognostic accuracy compared to using the ratio alone, with an AUC of 0.821. Conclusion:The admission serum glucose-to-potassium ratio is a valuable predictor of mortality in severe TBI patients. The multivariate logistic regression model based on heart rate and GCS score helps improve prognostic accuracy compared to using the ratio alone.
