The ideal SAH grading scale as per Rosen should include these four points
1. Aid clinicians in making patient management decisions that are infl uenced by the severity of SAH
2. Guide prognosis so that clinicians, patients, and family members can have appropriate expectations
for outcome. In this role, it is also essential for clinicians to thoroughly understand the prognostic
limitations of the grading scale
3. Facilitate communication between physicians to describe individual patients and to compare similar
groups of patients in multicenter studies that examine the impact of new treatment strategies
4. Enable clinicians to track a patient's status serially to detect and quantify changes in the severity of
disease. This is a critical use, but most units probably use the GCS or a modifi cation thereof
will completely replace experienced clinical judgment but rather
will serve to enhance predictive models. The future of SAH predic-
tion models likely will include portions of the scales in use today
possibly in combination with novel variables, such as biomarkers or
genetic susceptibility fi ndings obtained at admission.
