Method evidence record

Hunt and Hess Scale

The Hunt and Hess Scale is the most widely used clinical grading system for assessing severity and prognosis in subarachnoid hemorrhage (SAH) caused by ruptured intracranial aneurysm. Developed by neurosurgeons William Hunt and Robert Hess in 1968, the five-point ordinal scale measures level of consciousness and presence of focal neurological deficits. Hunt-Hess grade at admission is the single strongest predictor of 30-day mortality and functional outcome and guides urgency of neurosurgical intervention.
