“…Five questions are categorical (1-3 scale) and one question is on interval level (visual analog scale [VAS] 0-100) [10]. The Dutch language version of EQ-5D was used [4]. The Dutch EQ-5D translation has been performed using a forward-backward translation by the EuroQol Group and has been valued by standardized procedures throughout multiple countries (www.euroqol.org).…”

“…The EQ-5D categories measure five dimensions: mobility, self-care, activities of daily life (ADL), pain, and anxiety/ depression. For all states, utility indices were assigned, and in this study, the Dutch utility index or Dutch tariff was used [4]. The scale of the Dutch ariff ranges from À0.33 to 1.00 with higher scores reflecting higher QOL and 0 reflecting QOL equal to death.…”

“…Hence, the primary outcome of the therapy does not always relate to QOL in the same manner. Consequently, specific regression coefficients (tarrifs) were constructed for different countries [4,5]. Responsiveness of the EQ-5D was found to be moderate in a study in which exercise treatment was provided [6] and was sufficient for patients undergoing low-back surgery (area under the receiver operating characteristics [ROC] curve (AUC) of 0.77) [7].…”

“…The particular protocol for eliciting TTO valuations of EQ-5D health states used in the UK Measurement and Valuation of Health (MVH) study (Dolan, 1997) is widely used in part or full by other researchers. For example, it was used in the Netherlands (Lamers et al, 2006) and the US (Shaw et al, 2006).…”

A uniform time trade off method for states better and worse than dead: feasibility study of the ‘lead time’ approach

A uniform Time Trade Off method for states better and worse than dead: feasibility study of the 'lead time' approach SummaryThe way Time Trade Off (TTO) values are elicited for states of health considered 'worse than being dead' has important implications for the mean values used in economic evaluation. Conventional approaches to TTO, as used in the UK's 'MVH' value set, are problematic because they require fundamentally different tradeoffs tasks for the valuation of states better and worse than dead. This study aims to refine and test the feasibility of a new approach described by Robinson and Spencer (2006), and to explore the characteristics of the valuation data it generates. The approach introduces a 'lead time' into the TTO, producing a uniform procedure for generating values either >0 or <0. We used this lead time TTO to value 10 moderate to severe EQ-5D states using a sample of the general public (n=109). We conclude that the approach is feasible for use in valuation studies, and appears to overcome the discontinuity in values around 0 evident in conventional methods.

“…The EQ-5D is a generic instrument for measuring health-related QOL, which has been developed and validated in a number of European countries. 7,8 The EQ-5D evaluates five dimensions of health status: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has three levels of assessment that include 'no problems' , 'some problems' or 'severe problems' .…”

The aim of the Saga Challenge Antihypertensive Study (S-CATS), a single-arm, prospective and multi-center trial, was to evaluate the effectiveness of combined antihypertensive treatment with losartan and hydrochlorothiazide (HCTZ). Enrolled in the study were a total of 161 patients with hypertension, who in spite of treatment with an angiotensin receptor blocker (ARB) alone or an ARB and calcium channel blocker (CCB), had not been able to reach blood pressure control goals set by the Japanese Society of Hypertension Guidelines (JSH 2004). The ARBs were replaced with a combination pill containing losartan (50 mg) and HCTZ (12.5 mg), and this treatment was continued for 3 months. This change in therapy resulted in significant decreases in systolic (158 ± 14 to 137 ± 15 mm Hg, Po0.001) and diastolic (85 ± 11 to 76 ± 10 mm Hg, Po0.001) blood pressure and heart rate (73±3 to 72±3) during the study. The patients' quality of life (QOL) score, the EuroQol 5 dimensions (EQ-5D) and the visual analog scale (VAS) (n¼96; 70.0 (68.8-80.0) to 80.0 (70.0-90.0), Po0.01) all improved significantly. Another QOL score, the hypertension symptom score (HSS), which we originally developed for the S-CATS trial, decreased significantly (n¼93; 4.0 (1.0-9.0) to 2.0 (1.0-8.0), Po0.05). The Pittsburgh sleep quality index (PSQI), which is a psychometric assessment of subjective sleep quality, also decreased significantly (n¼45; 4.0 (2.0-7.0) to 3.0 (2.0-5.0), Po0.05). There was a significant correlation between a change in HSS (baseline value À3-months value) and a decrease in systolic blood pressure (n¼93; R¼0.241, Po0.05). These results suggest that an anti-hypertensive treatment combined with an ARB and a thiazide diuretic may improve patients' QOL, including sleep quality.
