"The WFNS subarachnoid haemorrhage grading system, proposed in 1988 by the World Federation of Neurosurgical Societies, uses the Glasgow Coma Scale and the presence of focal neurological deficits to grade the clinical severity of subarachnoid haemorrhage 1."
"Original WFNS grading scale (o-WFNS)"
"Original WFNS grading scale (o-WFNS)"
"The scale groups various GCS brackets and assigns them to a WFNS grade. The presence or absence of a focal neurological deficit is used to distinguish between grades II and III and is this distinction that causes the greatest observed inter-rater variability 2,3."
"The scale groups various GCS brackets and assigns them to a WFNS grade. The presence or absence of a focal neurological deficit is used to distinguish between grades II and III and is this distinction that causes the greatest observed inter-rater variability 2,3."
"grade I: GCS 15"
"grade II: GCS 13-14, without focal neurological deficit"
"grade III: GCS 13-14, with focal neurological deficit"
"grade IV: GCS 7-12"
"grade V: GCS 3-6"
"Modified WFNS grading scale (m-WFNS)"
"Modified WFNS grading scale (m-WFNS)"
"The proposed modified scale removes the incorporation of presence or absence of additional focal neurological deficit from the definition of grade II and III, and instead purely relies on the GCS 2,3."
