OBJECTIVE: To determine the strength of the correlation between the Hunt and 
Hess scale, Fisher score, Brussels coma score, World Federation of Neurosurgeons 
score, and Glasgow coma score and health-related quality of life.
METHODS: Evaluable questionnaires from 236 patients (5.6 years [± standard 
deviation, 2.854 years] on average after hemorrhage) were included in the 
analysis. Quality of life was documented using the MOS-36 item short form health 
survey. Because of the ordinal nature of the variables, Kendall tau was used for 
calculation. Significance was established as P ≤ 0.05.
RESULTS: Weak and very weak correlations were found in general (r ≤ 0.28). The 
strongest correlations were found between the Glasgow coma score and quality of 
life (r = 0.236, P = 0.0001). In particular, the "best verbal response" achieved 
the strongest correlations in the comparison, at r = 0.28/P = 0.0001. The Fisher 
score showed very weak correlations (r = -0.148/P = 0.012). The Brussels coma 
score (r = -0.216/P = 0.0001), Hunt and Hess scale (r = -0.197/P = 0.0001), and 
the World Federation of Neurosurgeons score (r = -0.185/P = 0.0001) revealed 
stronger correlations, especially in terms of the physical aspects of quality of 
life.
CONCLUSIONS: The Glasgow coma scale revealed the strongest, and the Fisher score 
showed the weakest correlations. Thus the Fisher score, as an indicator of the 
severity of a hemorrhage, has little significance in terms of health-related 
quality of life.
