Comparative StudyDoes the EQ-5D measure quality of life in schizophrenia?
Most health economic evaluations in mental care include outcome measures aimed at specific aspects of health, like symptom improvement, functional improvement and quality of life instead of generic preference based outcome measures. The health economic guidelines (NICE) recommend to include a generic preference based outcome measure, like EQ-5D, in health economic evaluations in order to allow for comparisons of health related quality of life of patient groups across different diseases, providing information particular useful to support health policy decisions and cost-effectiveness analysis. Although the EQ-5D is by far the most widespread outcome measure within the context of economic evaluations, its validity in psychiatric populations has not yet been established unambiguously. An increasing number of articles have tested the validity of the EQ-5D in comparisons with clinical measures in mental health, but only few studies have addressed the correlation between the EQ-5D and a condition-specific quality of life measure in mental health. ⋯ Mental health interventions often seek to improve the patients' quality of life in a broader perspective, like improving the patients' relationship with family, friends and other network, financial situation, employment and accommodation. If the EQ-5D is used as a single outcome in health economic evaluations of e.g. mental health community interventions, these factors may be overlooked. Based on a relatively small sample, we therefore recommend applying the EQ-5D together with condition-specific quality of life measures in future health economic evaluations in mental health.
