“…Two latent classes of MS were identified in regard to lifestyle behaviors. Previous studies have analyzed the latent classes of MS based on diagnostic criteria or types of physical activity; therefore, there are limitations to directly comparing the results of this study with those of previous studies (Boyko et al, 2011;Arguelles et al, 2015;Metzger et al, 2010;Lee et al, 2009). Nevertheless, the present results reinforce that latent classes exist that have different features.…”

“…The EQ-5D consists of multiple-choice questions that can be answered using a three-point scale ranging from 1 ("not affected") to 3 ("seriously affected") to determine current health status; this is applied to five items: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. In this study we used the EQ-5D Index, which was calculated by weighting each item (Lee et al, 2009). The variable was dichotomously re-categorized (9.0 = "high"; less than 9.0 = "low") for complex sample simple logistic regression.…”

The purpose of this study is to identify latent classes involving the health behaviors of patients with metabolic syndrome and to examine the effects of demographic characteristics and health-related lifestyles on their quality of life. The data was sourced from the database of the 2013 Korea health panel survey. Health behavior variables (smoking, drinking, body mass index, and physical activities) were dichotomously recategorized for latent class analysis. Two latent classes of metabolic syndrome, named 'low physical actor' and 'low physical actor with smoking and alcohol' were identified. Both latent classes showed statistically significant differences in demographic characteristics and EQ-5D index. Additionally, there were differences in the factors affecting quality of life between latent classes. This study's findings suggest that a tailored intervention based on features of the latent classes is required to improve the lifestyle and quality of life of metabolic syndrome patients.

Population norms for the EQ-5D-3L: a cross-country analysis of population surveys for 20 countries

et al. 2018

View full text Add to dashboard Cite

This study provides EQ-5D population norms for 20 countries (N = 163,838), which can be used to compare profiles for patients with specific conditions with data for the average person in the general population in a similar age and/or gender group. Descriptive EQ-5D data are provided for the total population, by gender and by seven age groups. Provided index values are based on European VAS for all countries, based on TTO for 11 countries and based on VAS for 10 countries. Important differences exist in EQ-5D reported health status across countries after standardizing for population structure. Self-reported health according to all five dimensions and EQ VAS generally decreased with increasing age and was lower for females. Mean self-rated EQ VAS scores varied from 70.4 to 83.3 in the total population by country. The prior living standards (GDP per capita) in the countries studied are correlated most with the EQ VAS scores (0.58), while unemployment appeared to be significantly correlated in people over the age of 45 only. A country's expenditure on health care correlated moderately with higher ratings on the EQ VAS (0.55). EQ-5D norms can be used as reference data to assess the burden of disease of patients with specific conditions. Such information, in turn, can inform policy-making and assist in setting priorities in health care.

“…Responses to the EQ‐5D‐3L were obtained from patients or their family members (when the patients could not communicate) by phone at 1‐year post‐IAT. The individual utility weights for the EQ‐5D‐3L‐based QALY were obtained from a South Korean general population survey (Lee et al., 2009). The direct saving of the institutional rehabilitation costs and the QALY gains were obtained for the >6‐hr and ≤6‐hr groups, by comparison with the 1‐year cost and QALY‐gain of the no‐recanalization group.…”

ObjectivesThrombolytic therapy is associated with favorable clinical outcomes after successful and rapid recanalization in patients with acute ischemic stroke. This study aimed to evaluate the cost benefits and clinical outcomes at 1 year after intraarterial thrombectomy (IAT) by the rapidity of the successful recanalization.Materials & MethodsClinical outcomes of and medical costs incurred by 230 patients with acute ischemic stroke who underwent IAT were compared by the rapidity from symptom onset to successful recanalization (2b/3 thrombolysis in cerebral infarction grade): ≤6‐hr (n = 143), >6‐hr (n = 31), and no‐recanalization (n = 56). Clinical outcomes including functional independence (0–2 modified Rankin Score), mortality, and home‐discharge checked at 1 year post‐IAT were compared among the three groups. Cost utility was calculated using quality‐adjusted life years (QALY) estimated using the EuroQol‐5 dimensions‐3 levels questionnaire and the fees paid for institutional rehabilitation during the year post‐IAT, and, was compared among the groups.ResultsPatients in the ≤6‐hr group showed higher functional independence (≤6‐hr, 70%; >6‐hr, 40%; no‐recanalization, 6%, p < .001) and home‐discharge rate (73%, 52%, 21%, and respectively, p < .001), and lower mortality (10%, 16%, and 43%, respectively, p < .001) at 1 year after IAT than other two groups. The cost utility of the ≤6‐hr group was $35,557/QALY higher than that of the >6‐hr group, and $27.829/QALY higher than no‐recanalization group.ConclusionsRapid and successful recanalization of the occluded intracranial vessels within 6 hr after the onset of symptoms resulted in markedly higher cost utility and functional independence at 1 year post‐IAT.
