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

Abstract

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.
