To value EQ-5D health states by a general Dutch public. EQ-5D is a standardised questionnaire that is used to calculate quality-adjusted life-years for cost-utility analysis.
A sample of 309 Dutch adults from Rotterdam and surroundings was asked to value 17 EQ-5D health states using the time trade-off method. Regression analysis was applied to the valuations of these 17 health states. By means of the estimated regression coefficients, which together constitute the so-called Dutch tariff, valuations can be determined for all possible EQ-5D health states. These values reflect the relative desirability of health states on a scale where 1 refers to full health and 0 refers to death. Societal valuations are necessary in order to correct life-years for the quality of life.
Complete data were obtained from 298 persons. Theywere representative for the Dutch population as far as age, gender and subjective health were concerned, but had a somewhat higher educational level. The estimated Dutch EQ-5D tariff revealed that the respondents assigned the most weight to (preventing) pain and anxiety or depression, followed by mobility, self-care and the activities of daily living. The Dutch tariff differed from the UK ('Measurement and Valuation of Health') tariff, which is currently used in Dutch cost-utility analyses. Compared to UK respondents, Dutch respondents assigned more weight to anxiety and depression and less weight to the other dimensions. Conclusion. The valuation of health states by this representative Dutch study group differed from the valuation that is currently used in Dutch cost-utility analyses.

    • "The EQ-5D covers five dimensions of health: mobility, self-care, daily activities, pain/discomfort and anxiety/depression; each with three levels of functioning: no problems, some problems and severe problems (Rabin & de Charro, 2001). Answers were used to compute an index value based on a Dutch valuation study, (Lamers, Stalmeier, McDonnell, Krabbe, & van Busschbach, 2005) ranging between + 1 and − 0.329, where 0 means death. The EQ-VAS is a graded, vertical line ranging from 0 (worst imaginable health state) to 100 (best imaginable health state). "

    ABSTRACT: Type 2 diabetes (T2DM) is associated with cognitive impairment. We examined whether undiagnosed cognitive impairment in T2DM-patients is associated with a reduced health status and depressive symptoms. In an observational study, 225 T2DM-patients aged ≥70years were examined at their homes and (some of them) at a memory clinic for undiagnosed cognitive impairment (dementia or mild cognitive impairment [MCI], defined according to internationally accepted criteria). Questionnaires assessing health status (SF-36, EQ-5D, EQ-VAS) and depressive symptoms (CES-D) were filled out. Health status and depressive symptoms were compared between patients with and without cognitive impairment. Patients with cognitive impairment (n=57) showed significantly lower scores on the physical and mental summary scores of the SF-36 than patients with normal cognition (difference: 3.5 (95%-CI 0.7-6.3, p=0.02, effect size 0.41) and 2.9 (95%-CI 0.3-5.6; p=0.03, effect size 0.37). EQ-5D index and EQ-VAS scores were significantly lower in patients with cognitive impairment. Depression (CES-D≥16) occurred almost twice as often in patients with cognitive impairment (RR 1.8; 95%-CI: 1.1-3.0). Undiagnosed cognitive impairment in T2DM-patients is associated with a reduced health status and more depressive symptoms. Detection of cognitive impairment in T2DM-patients identifies a vulnerable patient group that could benefit from tailored treatment and care. Copyright © 2015. Published by Elsevier Inc.

    • "Current health state is also rated on a scale ranging from 0 (worst imaginable state) to 100 (best imaginable state). Both Dutch and Turkish versions have been validated (Eser et al., 2007; Lamers et al., 2005). Self-harm and suicide attempt: A question asking about a suicide attempt will be used to assess the presence of a suicide attempt during the course of the study. "

    ABSTRACT: Abstract Background: The Turkish community living in Europe has an increased risk for suicidal ideation and attempted suicide. Online self-help may be an effective way of engagement with this community. This study will evaluate the effectiveness of a culturally adapted, guided, cognitive behavioural therapy-based online self-help intervention targeting suicidal ideation for Turkish adults living in the Netherlands and in the UK. This study will be performed in two phases. First, the Dutch online intervention will be adapted to Turkish culture. The second phase will be a randomized controlled trial with two conditions: experimental and waiting-list control. Ethical approval has been granted for the trials in London and Amsterdam. The experimental group will obtain direct access to the intervention, which will take 6 weeks to complete. Participants in the waiting-list condition will obtain access to the modules after 6 weeks. Participants in both conditions will be assessed at baseline, post-test and 3 months post-test follow-up. The primary outcome measure is reduction in frequency and intensity of suicidal thoughts. Secondary outcome measures are self-harm, attempted suicide, suicide ideation attributes, depression, hopelessness, anxiety, quality of life, worrying and satisfaction with the treatment.

    • "Health states defined by the five-dimensional descriptive system can be converted into a weighted health state index by applying scores from value sets elicited from general population samples that leads to a mean weighted health index ranging from 0 (dead) to 1 (optimal health).(Williams, 1995; Lamers et al., 2005) Covariates Age, sex, educational level (number of years of education beyond the age of 12), marital status (married or not married). The presence of depression and anxiety disorders was assessed by the corresponding sections of the CIDI 2.1, 12-month version. "

    ABSTRACT: Background Physical symptoms significantly impair health-related quality of life (HRQoL), but age effects and differential effects of medically unexplained symptoms (MUS) and medically explained symptoms (MES) have hardly been examined. Our objective was to determine the effect of age on the impact of MUS and MES on HRQoL.Methods In a population-based cohort (n = 946, aged 28–75 years), MUS and MES were measured using the Composite International Diagnostic Interview and HRQoL using the EuroQol-5 dimensions (EQ-5D). Using multiple linear regression, we regressed MUS, MES and their interaction with age on HRQoL, adjusted for socio-demographic variables and the presence of depressive and anxiety disorders. In case of significant interaction terms, age-stratified results will be presented.ResultsIn the whole study population, the association between MUS and HRQoL was stronger (β = −0.35; p < 0.001) than between MES and HRQoL (β = −0.26; p < 0.001). Adjusted for depressive and anxiety disorders, differences between these associations decline (MUS: β = −0.28, p < 0.001; MES: β = −0.25, p < 0.001). Age significantly interacted with number of MUS in explaining variance in HRQoL but not with the number of MES. The impact of MUS on HRQoL is much larger in people aged below 65 years (β = −0.39, p < 0.001) versus those aged 65 years and over (β = −0.21, p = 0.002). In the older group, the association between MUS and HRQoL lost significance when adjusted for depressive and anxiety disorders (β = −0.12 p = 0.062).Conclusion Our results show that age affects the association between MUS and HRQoL, which suggest that older persons cope better with MUS than younger persons.
