Predicting head injury prognosis using clinical scores (GCS and GCS-P score)

The Glasgow Coma Scale (GCS) and the Glasgow Coma Scale-Pupils (GCS-P) are critical tools for predicting prognosis in patients with head injury. Therefore, it is of interest to evaluate the comparative efficacy of both scales in determining mortality and functional recovery following traumatic brain injury. By integrating the Pupil Reactivity Score (PRS), the GCS-P addresses the "floor effect" of the traditional GCS and provides a more granular assessment of brainstem compromise. Our analysis demonstrates that the GCS-P offers superior predictive accuracy and a more linear correlation with patient outcomes than the GCS alone. Thus, we show that adopting the GCS-P enhances early clinical triage and provides a more robust framework for neurological prognostic modeling.
