BACKGROUND Utility scores are used to estimate Quality Adjusted Life Years (QALYs), applied in determining the cost-effectiveness of health care interventions. In studies where no preference based measures are collected, indirect methods have been developed to estimate utilities from clinical instruments. The aim of this study was to evaluate a published method of estimating the EuroQol-5D (EQ-...

OBJECTIVE Using inflammatory arthritis patients as an example, we investigate EuroQol-5D (EQ-5D) profiles resulting in states worse than death (WTD), and the heath status of patients occupying these states. METHODS Baseline data from two UK trials were used that reflected the range of arthritis states/severity found in routine practice. EQ-5D profiles resulting in negative valuations (i.e., s...

OBJECTIVES The purposes of this study were to analyse and compare aspects of validity (concurrent and discriminant) of the two widely used indirect utility instruments, the EuroQol-5D (EQ-5D) and the Short Form-6D (SF-6D) in a representative cohort of patients with rheumatoid arthritis (RA). METHODS Five hundred and eighty-three consecutive adult patients (435 women, 148 men) with RA and refe...

OBJECTIVE To assess the reliability and validity of the EuroQol (EQ-5D) for osteoarthritis of the knee (OA knee). METHODS Eighty-two patients with OA knee were asked to complete on two occasions, separated by 1 week, the EQ-5D, the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the 36-item short form of the Medical Outcomes Study (SF-36). RESULTS In this patient ...

BACKGROUND The European Quality of Life 5-Dimensions questionnaire is one of the most commonly used measures of health-related quality of life. OBJECTIVES To present the feasibility, reliability and validity of the Hebrew version of the EQ-5D. METHODS We conducted face-to-face interviews with a representative sample (n = 1666) of the Israeli Jewish population. The data collected included de...

BACKGROUND A number of different measures can be used within cost-utility analyses, we compared results according to both the EQ-5D and SF-6D. METHODS A randomized trial was conducted to compare 4 options for people with knee pain. Over the 2 year trial period, the change in cost to health-service was estimated, and both the EQ-5D and SF-6D were used to estimate the change in quality-adjusted...

OBJECTIVE To test the feasibility and validity of the EQ-5D (a widely used generic (disease non-specific) quality of life (QoL) instrument which allows comparisons between different patient groups and the general population) to assess QoL in patients with Parkinson's disease. METHODS All 124 patients with Parkinson's disease seen in a community based study on the prevalence of parkinsonism we...

BACKGROUND Accurately assessing changes in the quality of life of older people living permanently in nursing homes is important. The multi-attribute utility instrument most commonly used and recommended to assess health-related quality of life in the nursing home population is the three-level EuroQol EQ-5D-3L. To date, there have been no studies using the Health Utilities Index Mark III (HUI3)....

OBJECTIVES We assessed health-related quality of life (HRQOL), its associated factors, and examined measurement properties of the EuroQol - 5 Dimensions - 5 Levels (EQ-5D-5L) in HIV/AIDS patients. METHODS A cross-sectional multi-site survey was conducted in 1016 patients (age: 35.4 ± 7.0 years; 63.8% male) in three epicenters of Vietnam. Internal consistency reliability, convergent validity, ...

OBJECTIVES Cost-effectiveness analysis (CEA) is essential for the comparison of treatments for rheumatoid arthritis (RA). CEA centres on accurate measurement of health utility (HU) preferences. Direct measures of HU in RA patients demonstrate weaker correlations with health status (functional disability and pain) than indirect measures. We examined whether demographic and psychosocial factors r...
