“…This is consistent with findings from non-stroke populations, suggesting a possibly important clinical relationship between frailty and HRQoL [24,26]. It is also noteworthy that the robust group had HRQoL comparable to a normal population [42][43][44].…”

Background Stroke survivors are known to have poorer health-related quality of life (HRQoL) than the general population, but less is known about characteristics associated with HRQoL decreasing through time following a stroke. This study aims to examine how in-hospital frailty is related to HRQoL from 3 to 18 months post stroke. Method Six hundred twenty-five participants hospitalised with stroke were included and followed up at 3 and/or 18 months post stroke. Stroke severity was assessed the day after admission with the National Institutes of Health Stroke Scale (NIHSS). A modified Fried phenotype was used to assess in-hospital frailty; measures of exhaustion, physical activity, and weight loss were based on pre-stroke status, while gait speed and grip strength were measured during hospital stay. HRQoL at 3- and 18-months follow-up were assessed using the five-level version of the EuroQol five-dimensional descriptive system (EQ-5D-5L) and the EuroQol visual analogue scale (EQ-5D VAS). We conducted linear mixed effect regression analyses unadjusted and adjusted for sex, age, and stroke severity to investigate the association between in-hospital frailty and post-stroke HRQoL. Results Mean (SD) age was 71.7 years (11.6); mean NIHSS score was 2.8 (4.0), and 263 (42.1%) were female. Frailty prevalence was 10.4%, while 58.6% were pre-frail. The robust group had EQ-5D-5L index and EQ-5D VAS scores at 3 and 18 months comparable to the general population. Also at 3 and 18 months, the pre-frail and frail groups had significantly lower EQ-5D-5L indices than the robust group (p < 0.001), and the frail group showed a larger decrease from 3 to 18 months in the EQ-5D-5L index score compared to the robust group (− 0.056; 95% CI − 0.104 to − 0.009; p = 0.021). There were no significant differences in change in EQ-5D VAS scores between the groups. Conclusion This study on participants mainly diagnosed with mild strokes suggests that robust stroke patients have fairly good and stable post-stroke HRQoL, while post-stroke HRQoL is impaired and continues to deteriorate among patients with in-hospital frailty. This emphasises the importance of a greater focus on frailty in stroke units. Trial registration ClinicalTrials.gov (NCT02650531).

“…The ndings are similar for age groups that overlap with those for 50-79 years in three Asian countries and Ireland [17,19,20,26]. Furthermore, compared to the youngest age group, those aged 30-39 years reported less problems with usual activities, which is comparable to the ndings from six countries [14,15,17,20,25,26].…”

“…National population norms are increasingly available for the EQ-5D-5L and to date include 14 countries: Bulgaria [14], China [15], Germany [16], Hong Kong [17], Italy [18], Indonesia [19], Ireland [20], Japan [21], Poland [22], Slovenia [23], Spain [24], Trinidad and Tobago [25], USA [2] and Vietnam [26]. Data were collected by computer assisted interview, face-to-face interview, on-line and self-completed (pen and paper).…”

“…The collection of population norms was the main objective of four studies while the remainder had other objectives including valuation and national health surveys, which also included the EQ-5D-5L questionnaire. Samples size ranged from approximately 1000 [14], the level required for EQ-5D-5L valuation studies, to over 20 000 in the Spanish National Health Survey [24]. Most studies reported norms for the EQ-5D-5L dimensions, index and EQ VAS scores across categories of age and sex, with other socioeconomic variables including education level, being less widely reported [2,[14][15][16][17][18][19][20][21][22][23][24][25][26].…”

Purpose: To provide the first Norwegian EQ-5D-5L and EQ VAS population norms for the adult general population. Methods: Postal survey of a random sample of 12,790 Norwegians identified through the National Registry of the Norwegian Tax Administration. Norms are shown for the five EQ-5D-5L dimensions, EQ-5D index and EQ VAS scores for seven age categories, males, females and education level. Results: There were 3,200 (25.9%) respondents to 12,263 correctly addressed questionnaires. The EQ-5D-5L dimensions, EQ VAS and background questions were completed by 3,120 (24.6%) respondents. The mean age (SD) was 50.9 (21.7); range 18 to 97 years. The youngest age group of 18-29 years and oldest of 80 years and over had the highest (n=691) and lowest (n=239) number of respondents respectively. Compared to the general population, the respondents comprised a greater number of females, younger and older ages, and had a higher education level. 32% of respondents reported no health problems on the EQ-5D-5L. From the youngest to oldest age groups, there was a general decline in health as assessed by the EQ-5D-5L. The exception was for anxiety/depression, where the youngest age groups had the poorest health. Apart from self-care, women reported poorer health than men, as assessed by the EQ-5D-5L; EQ VAS scores were similar for men and women. Higher levels of health (EQ-5D index, EQ VAS scores) were found with increasing levels of education. Conclusion: The population norms will improve interpretation of EQ-5D-5L and EQ VAS scores in Norwegian applications including clinical practice, clinical and health services research, and national quality registers where EQ-5D-5L is the most widely used patient-reported instrument.

“…The EQ-VAS reference data can often yield a table of mean(s)/median(s) EQ-VAS scores by age-sex groups, while the mean(s)/median(s) EQ-5D-5L indexes were derived from the national value set for the EQ-5D-5L indexes reference data [20]. The population norms using the EQ-5D-5L were developed globally, from Western countries [21][22][23][24][25][26][27][28][29][30] to Asian countries [31][32][33][34][35][36][37]. A hint of population norms using the EQ-5D-5L for the Vietnamese has been done elsewhere, but the study included an urban population only, and furthermore, used Thai preferences [37].…”

PurposeThis study aims to provide EQ-5D-5L reference data of the general Vietnamese population and to test the EQ-5D-5L’ known-groups validity among people living with hypertension in Vietnam.MethodsThe EQ-5D-5L population norms were obtained via a representative sample from a general population of 1200 adults. Outcomes of the population norms were presented through five dimensions and five levels, EQ-VAS, and EQ-5D-5L indexes. Descriptive statistics of these outcomes were categorised by gender and age groups. Evidence of the known-groups validity was based on a sample of 577 non-hypertensive adults, 242 individuals with undiagnosed and 477 individuals with diagnosed hypertension. A hypothesis was formulated that people with worse health status would have lower EQ-VAS and EQ-5D-5L indexes. ResultsFor the EQ-5D-5L population norms, 54.4% of the respondents reported having full health. The mean EQ-VAS and EQ-5D-5L indexes were 81.10 and 0.94, respectively. The EQ-VAS and EQ-5D-5L indexes were higher among males, people at younger ages, those with more education, a paid job, and single. The mean EQ-VAS and EQ-5D-5L indexes of people in the diagnosed hypertension group were statistically significantly lower than they were in the other two groups. ConclusionThe EQ-5D-5L population norms were derived for the Vietnamese general population. The EQ-5D-5L can distinguish the quality-of-life differences among Vietnamese with hypertension.
