Association Between Glasgow Coma Scale Trajectory and In‐Hospital Mortality in Traumatic Brain Injury in the <scp>ICU</scp>: A Retrospective Cohort Study

These findings enable nurses to recognise neurological evolution patterns rather than relying on isolated measurements. Trajectory analysis helps identify high-risk patients requiring vigilant monitoring and those showing improvement patterns suitable for rehabilitation consideration. Particularly in elderly and heart failure patients, GCS trajectories should be interpreted with caution, as similar patterns may have different prognostic implications. Incorporating trajectory pattern recognition enhances care planning, resource allocation and team communication across shifts.
