ABSTRACT We sought to compare the ability of the EQ-5D, Health Utilities Index Mark 2 (HUI2), and HUI Mark 3 (HUI3) index scores to discriminate between respondents based on the presence or absence of chronic medical conditions in a population health survey.
Secondary analyses were conducted with data from a probability sample (n = 3480, mean age: 42.5 years, male: 42.4%, Hispanic: 28.6%) of the 2001 noninstitutionalized US general adult population. F-statistic ratios were used to evaluate the relative efficiency of the EQ-5D, HUI2, and HUI3 in differentiating respondents with or without each of 18 chronic medical conditions, and differentiating respondents with low- or high-burden conditions.
In comparing respondents with and without chronic medical conditions, the F-statistic values of these 3 indices were not significantly different, except for EQ-5D versus HUI2 [mean F-statistic ratio: 0.79, 95% confidence interval (CI): 0.59-0.98]. In comparing respondents with a low-burden condition with those with a high-burden condition, the F-statistic values of EQ-5D and HUI2 index scores were similar, while those for EQ-5D versus HUI3 (mean: 0.79; 95% CI: 0.66-0.92) and for HUI2 versus HUI3 (mean: 0.83; 95% CI: 0.71-0.95) were significantly less than 1.0. The overall ceiling effects of the EQ-5D, HUI2, and HUI3 index scores were 48.9%, 15.4%, and 15.3%, respectively.
Although the EQ-5D seems to be marginally less informative, the EQ-5D, HUI2, and HUI3 index scores were generally comparable in determining health burden of chronic medical conditions in this population health survey data.

    • "The EQ-5D is a widely used health utility index that can be derived from SF-36 scales [26]. It provides a single general measure of health status that can be used in economic analyses and to track the impact of healthcare interventions, and has been shown to be useful in a number of conditions [27] [28] [29] [30] [31] [32].

    ABSTRACT: Objective: Researchers have identified significant limitations in some currently used measures of health literacy. The purpose of this paper is to present data on the relation of health-related quality of life, health status, and health service utilization to performance on a new measure of health literacy in a nonpatient population. Methods: The new measure was administered to 475 English- and Spanish-speaking community-dwelling volunteers along with existing measures of health literacy and assessments of health-related quality of life, health status, and healthcare service utilization. Relations among measures were assessed via correlations and health status and utilization was tested across levels of health literacy using ANCOVA models. Results: The new health literacy measure is significantly related to existing measures of health literacy as well as to participants' health-related quality of life. Persons with lower levels of health literacy reported more health conditions, more frequent physical symptoms, and greater healthcare service utilization. Conclusion: The new measure of health literacy is valid and shows relations to measures of conceptually related constructs such as quality of life and health behaviors. Practice implications: FLIGHT/VIDAS may be useful to researchers and clinicians interested in a computer administered and scored measure of health literacy.

    • "The EQ-5D questionnaire was selected because it has been used in testing, albeit in a limited way in breast biopsy [22] [23]. The EQ-5D questionnaire has pronounced ceiling effects in prior literature [24] [25] [26]. The version used for many years has three levels in each of five attributes, allowing for 243 health states.

    ABSTRACT: The Testing Morbidities Index (TMI) was developed to measure the effects of any diagnostic or screening procedure on health-related quality of life (HRQOL); it includes seven domains incorporating mental and physical aspects before, during, and after testing. To add to prior work on the validity of the TMI classification, responsiveness of a summated scale version was evaluated in 71 colonoscopy patients. Further data on construct validity were also obtained. Patients enrolled in the study when scheduling colonoscopy days to weeks beforehand. The baseline survey included the EuroQol five-dimensional (EQ-5D) questionnaire with five levels in each attribute (EQ-5D-5L questionnaire) and its visual analogue scale (VAS) assessment (EQ-VAS), the Short Form 12 version 2 (SF-12v2) component summary scores and six-dimensional health state short-form (derived from the short-form 12v2 health survey [SF-6D] utilities), and an original construct-specific VAS (CS-VAS) for usual HRQOL using utility scale anchors. The TMI's highest possible summated score (all best levels) served as its baseline. Survey data were generally obtained by telephone interview. A postprocedure survey was given to patients after colonoscopy and interviews conducted as soon as possible after the day of the procedure. The postprocedure survey included the SF-12v2/SF-6D, EQ-5D questionnaire instruments, TMI items, and a CS-VAS incorporating the overall HRQOL effects of colonoscopy. Standardized response means showed greatest responsiveness by the TMI (-1.52) followed by the CS-VAS instruments (-0.42). The EQ-5D-5L questionnaire, the EQ-VAS, and the SF-12 component summaries were unresponsive, and the SF-6D was minimally responsive (-0.05). Correlation of the post-CS-VAS with the TMI was substantial (r = -0.52), suggesting TMI construct validity. Moderate to strong correlation of the baseline CS-VAS with standard indexes was observed (r = 0.54-0.81). The TMI appears responsive and exhibits further evidence of construct validity.

    • "They reported significantly lower utilities (estimated using indirect methods) for mild pain than for no pain (p < 0.0001), suggesting a greater value for treatments that eliminate migraine altogether compared with those that reduce migraine to a mild level. Luo et al. (2009) compared the ability of the EQ-5D and the HUI Mark 2 (HUI2) and HUI3 index systems to discriminate between the presence or absence of chronic medical conditions, and found differences in utility values obtained for respondents with migraine (sampled either outside of or during an attack) on each of the three instruments (0.82, 0.80, and 0.72, respectively), suggesting utility value elicitation can be affected by the methods employed [13]. To our knowledge, there are currently no studies that have estimated utility values for migraine pain severity levels and outcomes using the EQ-5D in a UK population of migraineurs. "

    ABSTRACT: To estimate utility values for different levels of migraine pain severity from a United Kingdom (UK) sample of migraineurs. One hundred and six migraineurs completed the EQ-5D to evaluate their health status for mild, moderate and severe levels of migraine pain severity for a recent migraine attack, and for current health defined as health status within seven days post-migraine attack. Statistical tests were used to evaluate differences in mean utility scores by migraine severity. Utility scores for each health state were significantly different from 1.0 (no problems on any EQ-5D dimension) (p < 0.0001) and one another (p < 0.0001). The lowest mean utility, - 0.20 (95% confidence interval [CI]: -0.27 - -0.13), was for severe migraine pain. The smallest difference in mean utility was between mild and moderate migraine pain (0.13) and the largest difference in mean utility was between current health (without migraine) and severe migraine pain (1.07). Results indicate that all levels of migraine pain are associated with significantly reduced utility values. As severity worsened, utility decreased and severe migraine pain was considered a health state worse than death. Results can be used in cost-utility models examining the relative economic value of therapeutic strategies for migraine in the UK.
