Comments on the Risk Stratification for the In-Hospital Mortality in Subarachnoid Hemorrhage: The HAIR Score

Excerpt

The HAIR score was published in the August 2014 issue of Neurocritical Care as a tool to enable risk stratification of in-hospital mortality after subarachnoid hemorrhage (SAH) [1]. The scale features four variables: Hunt and Hess score, age, intraventricular hemorrhage, and re-bleeding that comprise a composite maximum score of 8. Several other factors, previously described as being associated with poor outcome after SAH, were not considered in the HAIR score, for example larger aneurysm size or the presence of global cerebral edema on follow-up CT scan. In their retrospectively reviewed cohort of 400 patients, Lee et al. demonstrated increasing mortality rates with incremental increases in HAIR scores across the entire spectrum of scores between 0 and 7. …
