Comparing the Full Outline of Unresponsiveness (FOUR) score and the Glasgow Coma Scale (GCS) for predicting outcomes in traumatic brain injury: a comparative study

The FOUR score is a reliable tool for assessing TBI severity and predicting outcomes, with performance comparable to the GCS. An admission FOUR score ≤12 was associated with poor neurological outcomes, increased need for advanced airway management, and long-term disability. By capturing additional neurological parameters beyond the GCS, the FOUR score may offer clinical advantages in ICU settings for early prognostication and management of patients with TBI.
