Long-term health-related quality of life after spontaneous nontraumatic subarachnoid hemorrhage: self and proxy reports in a 10-year period.

BACKGROUND: This study sought to examine health-related quality of life several years after spontaneous nontraumatic subarachnoid hemorrhage. Recent studies report impairments to be improved as far as normal levels. We question such an improvement in our own patient population over a period of 10 years. METHODS: The Medical Outcomes Study 36-Item and Medical Outcomes Study 12-Item Short-Form Health Surveys on health-related quality of life were used to question 236 patients and 235 proxies. The patients were assigned to 5 groups according to the time that had elapsed since their hemorrhage: 1 year N = 22, 2 years N = 36, 5 years N = 86, 8 years N = 61, and 10 years N = 31. Analyses of variance (ANOVA, Kruskal-Wallis) and correlation (Spearman, Kendall tau) were used in an exploratory approach. Significance was established as P ≤ 0.05. RESULTS: Over a period of 10 years, health-related quality of life is found to be impaired, and is reported as such by the patients themselves and their proxies. Comparison of the mean values between the groups, ie, 1, 2, 5, and 10 years, revealed no significant differences in health-related quality of life. The calculations with a view to correlations between the group means and time since hemorrhage also produced only very weak correlations of no significance. CONCLUSIONS: Health-related quality of life is impaired over a period of 10 years. Spontaneous nontraumatic subarachnoid hemorrhage should be regarded as a chronic cerebrovascular condition.

Health-related quality of life after spontaneous subarachnoid hemorrhage measured in a recent patient population.

OBJECTIVE: This study sought to determine the impact of spontaneous subarachnoid hemorrhage (SAH) on health-related quality of life (HRQOL). METHODS: Data were taken retrospectively from 601 patients (219 male, 382 female) treated between 1998 and 2008. Questionnaires concerning HRQOL were circulated prospectively, and the responses from 253 patients (81 male, 172 female) were analyzed. The questionnaires comprised the standardized Short-Form 36 (SF-36) and Short-Form 12 (SF-12) Health Surveys, a number of nonstandardized questions, and visual analogue scales. Statistical analysis of the results was exploratory, using unifactorial ANOVA (Scheffe), multivariate analyses of variance. RESULTS: The HRQOL is reduced considerably by SAH and remains so for a period of 10 years. Physical and emotional domains are primarily affected, but also cognitive functions, including memory and concentration in particular. Similarly, certain roles are affected that prove difficult to rehabilitate after acute care and cause serious debility in the long term. The Hunt and Hess Scale, Glasgow Outcome Scale, and seizures were found to have the greatest impact on HRQOL. CONCLUSIONS: Documentation of HRQOL after 6 to 12 months is useful because patients are often found to have a diminished HRQOL in the absence of a clear physical impairment. Because psychological, emotional, cognitive, and social functioning influence HRQOL in the long term, efforts at rehabilitation should focus in particular on improving such factors. Documentation of HRQOL is a useful, additive tool for consolidating and evaluating the outcome, and a treatment end point after SAH, respectively.

Which clinical variable influences health-related quality of life the most after spontaneous subarachnoid hemorrhage? Hunt and Hess scale, Fisher score, World Federation of Neurosurgeons score, Brussels coma score, and Glasgow coma score compared.

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.

Cerebral vasospasm and health-related quality of life after subarachnoid hemorrhage.

OBJECTIVE: To examine the influence of cerebral vasospasm on health-related quality of life after subarachnoid hemorrhage. An additional objective was to determine how the timing of nimodipine therapy can influence health-related quality of life. METHODS: Patients treated between 1998 and 2008 for nontraumatic subarachnoid hemorrhages were sent a standardized questionnaire for the purposes of documenting their health-related quality of life. Initially the patients were divided into two groups: those with and those without cerebral vasospasm after hemorrhage (radiologically confirmed). They were then differentiated according to four types of treatment options for vasospasm: 1) nimodipine since admission (N = 179); 2) nimodipine since diagnosis of vasospasm (N = 14); 3) no nimodipine/no vasospasm (N = 34); and 4) no nimodipine despite vasospasm (N = 5). Significance was established as P ≤ 0.05. RESULTS: Evaluable questionnaires were returned by 236 patients (68% women, mean age 56.35 ± 12.68 years; 32% men, mean age 54.57 ± 12.20 years). Health-related quality of life generally appeared to be impaired. Yet with the exception of the subscale (1 of 8) of physical role (P = 0.019), there were no differences between patients with and without vasospasm. Variations in the different treatment options revealed significant effects in terms of the component summaries and subscales: physical role and pain, general health, vitality, social functioning, emotional role, mental health, and mental component summary (P ≤ 0.04). CONCLUSIONS: Cerebral vasospasm had little influence on health-related quality of life in our patient population. Health-related quality of life cannot be used as the only argument in favor of treating cerebral vasospasm with nimodipine.
