*When data is insufficient to categorize it as ABF, it is scored as “not present.” **Abnormal GCS or FOUR score depends on patient status. For intubated patients who cannot be assessed for verbal components, <13 FOUR score or <12 GCS is abnormal. For all others, GCS<15 and FOUR score <16 is scored as abnormal.
