Conditional information
Result interpretation
Model performance:
- In a study bij Hunt & Huss (1968) including 275 cases, the mortality was 20% for patients admitted to the hospital at grade I or II, whereas in patients who reached the operating room for any procedure whatever at grade I or II, it was 14%. The difference in mortality was due to a number of instances of early fatal rebleeding.
- Worldwide, different scales are used to assess the clinical condition on admission after aneurysmal subarachnoid hemorrhage. In addition to the prognostic value, the inter-rater variability should be taken into account when deciding which scale preferably should be used.
- In a validation study by Degen et al (2011) including 50 subarachnoid hemorrhage patients, the Hunt and Hess scale showed moderate interobserver agreement (weighted kappa value: 0.48; 95% CI, 0.36–0.59). The World Federation of Neurological Surgeons and the Prognosis on Admission of Aneurysmal Subarachnoid Hemorrhage scales both showed good interobserver agreement (0.64 and 0.60 respectively) with overlapping CI.
