Subarachnoid hemorrhage grading scales

Hunt and Hess scale

REFERENCES

The Hunt and Hess scale , introduced in , is one of the grading systems used to classify the severity of a subarachnoid hemorrhage based on the patient's clinical condition.

Numerous systems are reported for grading the clinical condition of patients following subarachnoid hemorrhage SAH. This article reviews the advantages and limitations of these scales as well as more recent proposals for other grading systems based on these scales with or without addition of other factors known to be prognostic for outcome after SAH. There remain substantial deficits in the literature regarding grading of patients with SAH.

Subarachnoid hemorrhage grading scales

We are thankful for interest 1 in our recently published 2 ruptured brain arteriovenous malformation AVM grading scale, and the opportunity to respond. Hemorrhage volume and AVM size are important considerations in the management of intracranial bleeds. Indeed, other studies have demonstrated the relationship between intracerebral hemorrhage ICH volume and patient mortality eg, ICH score 3 , and the role of AVM size in surgical decision-making eg, Spetzler-Martin score 4. While the objectives of these studies are distinct from the purpose of the RAGS score ie, to predict clinical outcomes based on initial clinical presentation after AVM rupture , we also believed AVM size and hemorrhage volume were important, so they were included in initial models. Neither hemorrhage volume nor AVM size had a statistically significant impact on the model, meaning that the presence of either variable did not significantly improve the model's predictive ability; thus, they were not included in the RAGS score. A key objective of the RAGS score is to provide a simple, easy-to-use, quickly calculable score for everyday use, thus overcoming the limitations of more complicated and cumbersome grading systems.

Risk factors for mortality after subarachnoid hemorrhage: a retrospective observational study. Subarachnoid hemorrhage is an important cause of morbidity and mortality. The aim of the study was to determine predictors of mortality among patients with subarachnoid hemorrhage hospitalized in an Intensive Care Unit. This is a retrospective study of patients with subarachnoid hemorrhage admitted to the Intensive of our institution during a 7 year period We included in the study patients with subarachnoid hemorrhage. Multivariate analysis of patients with subarachnoid hemorrhage following an aneurysm rupture revealed that mortality was significantly associated with septic shock and hypernatremia during the first 72 hours of Intensive Care Unit stay, while early treatment of aneurysm clipping or endovascular coiling within the first 72 hours was identified as a predictor of a good prognosis. Transferred patients with subarachnoid hemorrhage had lower survival rates.

Numerous grading scales have been proposed to predict the outcome of aneurysmal subarachnoid hemorrhage SAH ; however, these have not been validated in angiogram-negative SAH patients. The predictive performance of the grading scales was assessed via evaluation of distribution, trend, association, and discrimination. Both grading scales indicated a significant trend between scores and outcome , and association with the outcome. However, the mFS performed with increased accuracy when predicting mRS However, angiogram-negative SAH still has a definite incidence of delayed cerebral ischemia DCI and poor outcome, particularly in patients with a nonperimesencephalic bleeding pattern [ 1 ]. However, none of these were initially designed for use in angiogram-negative SAH patients. These grading scales were derived and validated in the aneurysmal SAH patients but were also commonly used in the clinical assessment and prognosis of angiogram-negative SAH patients.

Past studies revealed the prognosis differed between aneurysmal subarachnoid hemorrhage aSAH patients with surgical clipping and endovascular coiling. We retrospectively reviewed aSAH patients in our institution to investigate the effectiveness of grading scores between two groups.
