Creation and validation of a mortality risk prediction model for ICU patients with traumatic brain injury: a multicenter retrospective cohort study

This study developed a predictive model that estimates short-term mortality for TBI patients in the ICU using seven routinely available clinical variables. The model demonstrated robust performance in external validation. Its design, which enables multi-timepoint assessment, may facilitate risk stratification and has the potential to support clinical decision-making, pending future prospective validation.
