An Exploratory Study of Alternative Time Frames and Descriptors for EQ-5D-5L in Obstructive Airway Diseases Using Mixed Methods.

OBJECTIVES: EQ-5D-5L with its recall time of "today" may limit its ability to capture episodic symptoms and exacerbations in chronic obstructive airway diseases (OAD). We examined whether longer time frames and changing the intensity response scales to frequency scales could improve the measurement properties of EQ-5D-5L. METHODS: We used a mixed-method design starting with in-depth interviews with 20 patients and clinicians to elicit preferred time frames using concept elicitation techniques and content analyses. We then administered the top 4 preferred variants using 1- and 4-weeks' time frames with the original intensity or an alternative frequency response scale alongside EQ-5D-5L and St George Respiratory Questionnaire to OAD patients during 2 different visits. We compared the ceiling effects and construct validity by testing a priori hypotheses in relation to St George Respiratory Questionnaire and clinical outcomes via correlation and receiver operating characteristic (ROC) analyses, respectively. Follow-up patients were categorized into "better," "stable," and "worse" groups to assess reliability using intraclass correlation coefficient (ICC) or Cohen's Kappa (k) and responsiveness using ROC analysis. RESULTS: A total of 184 patients (mean [SD] age: 54[18]; female: 37.0%) completed baseline assessments. A total of 120 patients also completed follow-up assessments (mean [SD] interval: 2.8 [1.7] months). The ceilings were lower in the variants compared with EQ-5D-5L (P < .001). Reliability of the variants were comparable to or higher than EQ-5D-5L. The c-statistic values derived from ROC analyses of the variants were consistently higher than EQ-5D-5L. CONCLUSIONS: Use of longer time frames with the original intensity or the frequency response scales may improve EQ-5D-5L's psychometric properties in OAD patients.

Exploring the Comparability Between EQ-5D and the EQ Health and Wellbeing in the General Australian Population.

OBJECTIVES: The EQ Health and Wellbeing (EQ-HWB) is a novel measure that conceptually overlaps with the 5-level EQ-5D (EQ-5D-5L) while capturing broader dimensions of health and well-being. This study aimed to explore the extent to which the EQ-HWB and EQ-5D-5L capture overlapping or complementary constructs and to explore the discriminative ability of the EQ-HWB Short version (EQ-HWB-S) as a multiattribute utility instrument in the Australian setting. METHODS: A secondary analysis of data from a nationally representative cross-sectional survey of 2002 Australian adults was performed. The survey included socioeconomic questions and health characteristics and the EQ-HWB and EQ-5D-5L instruments. Convergent and known-group validity were evaluated through Spearman rank correlation and multivariable regression analyses, respectively. An exploratory factor analysis was also performed to explore the underlying constructs of the 2 measures. RESULTS: Correlation coefficients varied from moderate to strong (rs ≥ 0.40) between the EQ-5D-5L and the corresponding EQ-HWB dimensions (all P < .001). Based on the exploratory factor analysis, both instruments measure similar underlying constructs, with the EQ-HWB capturing broader aspects of well-being. The known-group analysis demonstrated the relative discriminative ability of the EQ-HWB-S in capturing broader aspects of health and well-being. CONCLUSIONS: The EQ-HWB was at least moderately correlated with the EQ-5D-5L in overlapping domains/dimensions and demonstrated greater sensitivity in participants with mental health problems versus the EQ-5D-5L. Our findings support future research exploring the value of the EQ-HWB-S as a multiattribute utility instrument for the general Australian population.

EQ-5D-5L Population Norms and Quality-Adjusted Life Expectancy by Sociodemographic Characteristics and Modifiable Risk Factors for Adults in Queensland, Australia.

OBJECTIVES: Over half of Australia's disease burden is due to morbidity, predominantly chronic conditions. Health-related quality of life instruments provide measures of morbidity and health status across different dimensions with EQ-5D being one of the most widely used. This study reports EQ-5D-5L general population norms for Queensland, Australia using the recently published Australian value set. METHODS: Population survey results from cross-sectional computer-assisted telephone interviews for Queensland adults in 2022 and 2023 were analyzed. EQ-5D-5L, as well as modifiable risk factors and sociodemographic data were collected. Using the recently published final Australian EQ-5D-5L value set, mean utility scores were calculated for Queensland, as well as by sociodemographic characteristics, including remoteness and socioeconomic area-based measures, and modifiable risk factors, such as smoking and body mass index. Results were combined with life tables to estimate quality-adjusted life expectancy (QALE) for subgroups with different lifestyles. RESULTS: The EQ-5D utility score for the Queensland adult population was 0.916. Smoking daily, being obese or older in age, or living in the most disadvantaged socioeconomic area were associated with lower mean scores. QALE was 6.1 and 7.9 years shorter than the life expectancy for Queensland males and females, respectively, but generally, those who reported having healthier lifestyles had higher mean utility scores and thus longer QALE. CONCLUSIONS: In addition to reporting Queensland EQ-5D-5L general population norms, these results demonstrate potential QALE gains in people following healthier lifestyles. The results support investment in prevention and may motivate further studies in this important area.

Health inequity assessment in Brazil: is EQ-5D-3L sensible enough to detect differences among distinct socioeconomic groups?

BACKGROUND: Multidimensional health-related quality of life (HRQOL) instruments, such as the EQ-5D, are increasingly used to assess inequalities in health. However, it is necessary to explore the ability of these instruments to capture differences between population groups, especially in low/middle-income countries. This study aimed to investigate whether the EQ-5D-3L instrument can detect differences in HRQOL between groups of different socioeconomic status (SES) in Brazil. METHODS: Data collection occurred during the Brazilian EQ-5D-3L valuation study and included respondents aged 18 to 64 years enrolled in urban areas. SES was aggregated into three categories: "higher" (A and B), "intermediate" (C) and "lower" (D and E). EQ-5D-3L index was calculated considering the Brazilian value set. A mixed-effects regression model was estimated with random effects on individuals and marginal effects on SES, sex, and educational attainment. Odds ratios for the chance of reporting problems for each EQ-5D dimension were estimated by logistic regression. RESULTS: A total of 9,148 respondents were included in the study. Mean age was 37.80 ± 13.13 years, 47.4% were men and the majority was ranked as classes B or C (38.4% and 50.7%, respectively). Participants in lower SES classes reported increasingly poorer health compared to individuals in higher classes. The mean EQ-5D-3L index decreased as SES deteriorates being significantly higher for classes A and B (0.874 ± 0.14) compared to class C (0.842 ± 0.15) and classes D and E (0.804 ± 0.17) (p < 0.001). The same was observed for the mean EQ-VAS scores (84.0 ± 13.8 in classes A and B, 81.0 ± 17 in class C and 78.3 ± 18.7 in class C [p < 0.001]). The multivariate analysis confirmed that SES is an independent factor that effects EQ-5D-3L index measures. Participants in intermediate and lower SES classes have a statistically significant lower EQ-5D-3L index compared to participants in classes A and B, regardless of age, sex, and educational attainment. CONCLUSION: In a Brazilian population sample, the EQ-5D-3L instrument was able to detect important differences between groups with distinct socioeconomic statuses (SES). The EQ-5D-3L is useful for exploring inequities in health.

Prognostic factors for deterioration of quality of life one year after admission to ICU for severe SARS-COV2 infection.

PURPOSE: Patients with COVID-19 present long-term symptoms collectively known as "post-COVID syndrome". Long-term manifestations are more frequent in patients requiring admission to Intensive Care Units (ICU), but the risk factors for their development are still unknown. This study explores the quality of life of patients with severe COVID-19 one year after their discharge from ICU. METHODS: Prospective observational study including 106 patients admitted to the ICU of a tertiary care hospital between March and August 2020. We analysed quality of life using the EuroQol-5D index (EQ-5D). We evaluated as possible risk factors associated with a worse value of the EQ-5D index the medical record, the clinical situation at hospital admission, the clinical situation at ICU admission and evolution in the ICU. As a secondary objective, we explored the presence of other frequent symptoms. RESULTS: Most patients (55.4%) reported that their quality of life worsened one year after admission. The mean perceived health status, on the EQ-VAS scale (0-100), was 70.4, with a median of 70 (RI 60-90). The median EQ-5D index was 0.91 (RI 0.76-1). The factors independently related to lower quality of life were female sex and duration of mechanical ventilation. Almost all (91%) of the patients had sequelae one year after discharge from the ICU. The most frequent manifestations were neuropsychiatric (71%). CONCLUSIONS: Critically ill COVID-19 patients worsen their quality of life more than one year after discharge. Female sex and duration of mechanical ventilation predict a lower quality of life assessed by the EQ-5D index.

Population-level norm values by EQ-5D-3L in Hungary - a comparison of survey results from 2022 with those from 2000.

PURPOSE: Although population norms of the EQ-5D-3L instrument had been available in Hungary since 2000, their evaluation was based on a United Kingdom (UK) value set. Our objective was to estimate the population norms for EQ-5D-3L by using the new Hungarian value set available since 2020, to extend the scope to adolescents, and to compare with norms from 2000. METHODS: A cross sectional EQ-5D-3L survey representative of the Hungarian population was conducted in 2022. The EQ-5D-3L dimensional responses were analyzed by age and sex and compared with the survey from 2000, by estimating population frequencies with their 95% confidence intervals; index values were evaluated by both value sets. RESULTS: Altogether, 11,910 respondents, aged 12 or more (578 between 12 and 17), completed the EQ-5D-3L. There was a notable improvement in reporting problems for both sexes (age 35-64) regarding the pain/discomfort and anxiety/depression compared to 2000. Below the age 44, both sexes had an EQ-5D-3L index plateau of 0.98, while above the age 55, men tended to have numerically higher index values compared to women, with the difference increasing with older age. Improvement in dimensional responses were also translated to numerically higher index values for both sexes between ages 18 and 74 compared to 2000. Multivariate regression analysis showed that higher educational attainment, lower age, larger household size, and active occupational status were associated with higher index values. CONCLUSION: Over the past 22 years, there was a large improvement in HRQoL of the middle-aged to elderly men and women in Hungary.

Health states can be described by a combination of statements of health-related quality of life measures. 'Value sets' are numerical expressions of how preferred a health state is. The provision of population-level health-related quality of life estimates (also known as 'population norms') are expected to improve the precision of patient-level clinical decision making, and health economic and public health studies. However, preference towards these health states is influenced by culture, resulting in differences across populations. While responses for the EQ-5D-3L instrument for adults have been available in Hungary since 2000, the evaluation of these responses was based on a 'value set' from the United Kingdom, rather than a Hungarian one.This research, utilizing the newly introduced Hungarian 'value set' (available since 2020) for the EQ-5D-3L instrument, offers a larger sample size, inclusion of adolescents and potentially improved sampling compared to the prior research conducted in 2000. Comparison of the two surveys allows us to estimate changes in both dimensional responses and overall health-related quality of life of the population over a 20-year time horizon, while we also compare the impact of different 'value sets' on health-related quality of life assessment. A large EQ-5D-3L improvement was observed in middle-aged-to-elderly people.

Associations between the EQ-5D-5L and exacerbations of chronic obstructive pulmonary disease in the ETHOS trial.

PURPOSE: Exacerbations of chronic obstructive pulmonary disease (COPD) are associated with deteriorating health and health-related quality of life (HRQoL) among people with COPD during and after events. HRQoL data are key to evaluating treatment cost-effectiveness and informing reimbursement decisions in COPD. EuroQoL 5-dimension 5-level (EQ-5D-5L) utility scores, based on various HRQoL measures, are used in economic evaluations of pharmacotherapy. These analyses estimated associations between EQ-5D-5L utility scores and exacerbations (new and previous) in patients with moderate-to-very severe COPD. METHODS: Longitudinal mixed models for repeated measures (MMRM), adjusted for time and treatment, were conducted using data from the ETHOS study (NCT02465567); models regressed EQ-5D-5L on current and past exacerbations that occurred during the study, adjusting for other patient reported outcomes and clinical factors. RESULTS: Based on the simplest covariate adjusted model (adjusted for current exacerbations and number of previous exacerbations during the study), a current moderate exacerbation was associated with an EQ-5D-5L disutility of 0.055 (95% confidence interval: 0.048, 0.062) with an additional disutility of 0.035 (0.014, 0.055) if the exacerbation was severe. After resolving, each prior exacerbation was associated with a disutility that persisted for the remainder of the study (moderate exacerbation, 0.014 [0.011, 0.016]; further disutility for severe exacerbation, 0.011 [0.003, 0.018]). CONCLUSION: An EQ-5D-5L disutility of 0.090 was associated with a current severe exacerbation in ETHOS. Our findings suggest incorporating the effects of current, recently resolved, and cumulative exacerbations into economic models when estimating benefits and costs of COPD pharmacotherapy, as exacerbations have both acute and persistent effects.

Inferior long-term outcomes after surgery for lumbar disc herniation in patients with prior lumbar spine surgery.

BACKGROUND: Previous lumbar spine surgery is a frequent exclusion criterion for studies evaluating lumbar surgery outcomes. In real-life clinical settings, this patient population is important, as a notable proportion of patients evaluated for lumbar spine surgery have undergone prior lumbar surgery already previously. Knowledge about the long-term outcomes after microdiscectomy on patients with previous lumbar surgery and how they compare to those of first-time surgery is lacking. METHODS: The original patient cohort for screening included 615 consecutive patients who underwent surgery for lumbar disc herniation, with a median follow-up time of 18.1 years. Of these patients, 89 (19%) had undergone lumbar spine surgery prior to the index surgery. Propensity score matching (based on age, sex, and follow-up time) was utilized to match two patients without prior surgery with each patient with a previous surgery. The primary outcome measure was the need for further lumbar spine surgery during the follow-up period, and the secondary outcome measures consisted of present-time patient-reported outcome measures (Oswestry Disability Index, EuroQol-5D) and present-time ability to carry out employment. RESULTS: Patients who received previous lumbar surgeries had a higher need for further surgery (44% vs. 28%, p = 0.009) and had a shorter time to further surgery than the propensity score-matched cohort (mean Kaplan-Meier estimate, 15.7 years vs. 19.8 years, p = 0.008). Patients with prior surgery reported inferior Oswestry Disability Index scores (13.7 vs. 8.0, p = 0.036). and EQ-5D scores (0.77 vs. 0.86, p = 0.01). In addition, they had a higher frequency of receiving lumbar spine-related disability pensions than the other patients (12% vs. 1.9%, p = 0.01). CONCLUSIONS: Patients with previous lumbar surgery had inferior long-term outcomes compared to patients without prior surgery. However, the vast majority of these patients improved quickly after the index surgery. Furthermore, the difference in the patients' reported outcomes was small at the long-term follow-up, and they reported high satisfaction with the results of the study surgery. Hence, surgery for these patients should be considered if surgical indications are met, but special care needs must be accounted for when deliberating upon their indications for surgery.

The psoas muscle index as a useful predictor of total hip arthroplasty outcomes.

INTRODUCTION: The aim of this study is to assess the association between the psoas muscle index (PMI) and total hip arthroplasty (THA) outcomes. This is a critical issue as sarcopenia has been associated with poor patient satisfaction post-THA. MATERIALS AND METHODS: This was a retrospective case-control study of 205 THAs, with a mean follow-up of 3.6 (range, 2.0-5.5) years. Age, sex, serum immune markers, spinopelvic parameters, PMI (quantified as the cross-sectional area of the psoas, bilaterally, at L3 divided by the individual's height squared), and patient-reported outcomes were compared between patients 'with' (n = 118) and 'without' (n = 87) achievement of a minimum clinically important difference (MCID) improvement in the EuroQol 5-Dimension (EQ-5D), post-THA. Logistic regression and receiver operating characteristic curve analyses were used to identify predictive factors. RESULTS: A ≥ MCID improvement in the EQ-5D was associated with the PMI (odds ratio, 0.75; 95% confidence interval, 0.63-0.91; P = 0.028), prognostic nutritional index (odds ratio, 0.85; 95% confidence interval, 0.45-0.94; P = 0.043), and age (odds ratio, 1.09; 95% confidence interval, 1.01-1.18; P = 0.044). After adjusting the PMI threshold to 4.0 cm2/m2 for females and 6.4 cm2/m2 for males, there were significant differences in serum factors (P = 0.041 for albumin and P = 0.016 for a prognostic nutritional index < 40), MCID (P < 0.001 for EQ-5D, P < 0.001 for low back pain, and P = 0.008 for the Hip Disability and Osteoarthritis Outcome Score Joint Replacement score), patient satisfaction (P = 0.003), and T1 pelvic angle (P = 0.030). CONCLUSION: The PMI, which is associated with nutritional status and global sagittal spinal deformity, does predict THA outcomes. Therefore, it can be useful when discussing THA expectations with patients.

Valuing the EQ Health and Wellbeing Short Using Time Trade-Off and a Discrete Choice Experiment: A Feasibility Study.

OBJECTIVES: The EQ Health and Wellbeing Short (EQ-HWB-S) is a new generic measure that covers health and wellbeing developed for use in economic evaluation in health and social care. The aim was to test the feasibility of using composite time trade-off (cTTO) and a discrete choice experiment (DCE) based on an international protocol to derive utilities for the EQ-HWB-S and to generate a pilot value set. METHODS: A representative UK general population was recruited. Online videoconference interviews were undertaken where cTTO and DCE tasks were administered using EuroQol Portable Valuation Technology. Quality control (QC) was used to assess interviewers' performance. Data were modeled using Tobit, probit, and hybrid models. Feasibility was assessed based on the distribution of data, participants, and reports of understanding from the interviewer, QC and modeling results. RESULTS: cTTO and DCE data were available for 520 participants. Demographic characteristics were broadly representative of the UK general population. Interviewers met QC requirements. cTTO values ranged between -1 to 1 with increasing disutility associated with more severe states. Participants understood the tasks and the EQ-HWB-S states; and the interviewers reported high levels of understanding and engagement. The hybrid Tobit heteroscedastic model was selected for the pilot value set with values ranging from -0.384 to 1. Pain, mobility, daily activities, and sad/depressed had the largest disutilities, followed by loneliness, anxiety, exhaustion, control, and cognition in the selected model. CONCLUSIONS: EQ-HWB-S can be valued using cTTO and DCE. Further methodological work is recommended to develop a valuation protocol specific to the EQ-HWB-S.

The relationship between patient-reported health-related quality of life and malnutrition risk in cirrhosis: an observational cohort study.

Patients with cirrhosis experience worse health-related quality of life (HRQoL), and attempts are warranted further exploration of modifiable factors to improve HRQoL. Data on the impact of malnutrition risk on HRQoL among cirrhosis are limited; thus, we aimed to strengthen understanding by clarifying the relationship between nutritional status and low HRQoL in patients with decompensated cirrhosis. Consecutive inpatients with cirrhosis attending our department within a tertiary hospital were studied. Generic health profiles and malnutrition risk were evaluated by the EuroQol-5D (EQ-5D) and Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) score, respectively. Multiple linear regression analysis was used to determine association of malnutrition risk with low HRQoL. In this cohort of 364 patients with median age of 64 years and 49·5 % male, 55·5 % of the study population reported impairment pertinent to HRQoL in at least one dimension in terms of the EQ-5D. Moreover, malnutrition risk (RFH-NPT score: ß coefficient = -0·114, P = 0·038) was proved to be independently associated with poor HRQoL in multiple analysis, after adjustment for significant variables like age, BMI and markers of decompensation. Notably, we found that health dimensions representing physical function (i.e. mobility, self-care and usual activities) are substantially affected, while malnourished patients reported less frequencies of complaints in other domain such as anxiety/depression. In conclusion, the risk of malnutrition assessed by the RFH-NPT score is independently associated with low HRQoL. It is operational to improve HRQoL by identifying patients at high malnutrition risk and providing timely nutrition treatment.

Estimating health related quality of life effects in vitiligo. Mapping EQ-5D-5 L utilities from vitiligo specific scales: VNS, VitiQoL and re-pigmentation measures using data from the HI-Light trial.

BACKGROUND: Vitiligo is reported to affect 2% of the world's population and has a significant impact on health related quality of life (HRQoL). The relationship between HRQoL and clinical outcomes used in vitiligo require further examination. Mapping condition specific measures of HRQoL: vitiligo specific quality of life instrument (VitiQoL), vitiligo noticeability scale (VNS) and vitiligo re-pigmentation scores (RPS) to the EQ-5D have not yet been reported. METHODS: Data collected from a randomised clinical trial (HI-Light) in vitiligo was used to develop mapping algorithms for the EQ-5D-5 L and the relationship between HRQoL, clinical outcomes and EQ-5D were investigated. Two EQ-5D-5 L value sets (Van Hout and Alava) using linear and non-linear models were considered. Logistic regression models were used to model the probability of vitiligo noticeability (VNS) in terms of RPS, EQ-5D and VitiQoL scores. RESULTS: Mapping from RPS appeared to perform better followed by VNS for the Alava crosswalks using polynomial models: Mean observed vs. predicted utilities of 0.9008 (0.005) vs. 0.8984 (0.0004) were observed for RPS. For VNS, mean observed vs. predicted utilities of 0.9008 (0.005) vs. 0.8939 (0.0003) were observed. For VitiQoL, mean observed vs. predicted utilities of 0.9008 (0.005) vs. 0.8912 (0.0002) were observed. For patients with the least re-pigmentation (RPS < 25%), a Total VitiQoL score of about 20 points gives around an 18% chance of vitiligo being no longer or a lot less noticeable. CONCLUSION: The algorithm based on RPS followed by VNS performed best. The relationship between effects from vitiligo specific HRQoL instruments and clinical RPS was established allowing for plausible clinically relevant differences to be identified, although further work is required in this area.

Effects of concurrent exercise on health-related quality of life in middle-aged women.

OBJECTIVE: This study aimed to evaluate the influence of a 16-week concurrent exercise program on health-related quality of life in middle-aged women. METHODS: A total of 150 middle-aged women from the FLAMENCO project (age range 45-60 years) were randomized into a counseling (n = 75) or an exercise (n = 75) group. The exercise group followed a 16-week (3 days/week, 60 min/session) concurrent exercise program (aerobic + resistance training). The counseling group attended conferences on a healthy lifestyle. Participants' health-related quality of life was assessed with the EuroQol plus, a visual analog scale and the 36-item Short Form Health Survey (SF-36), where greater values indicate a better health-related quality of life. RESULTS: The visual analog scale increased by 9.0% in the exercise group, whereas it only increased by 3.5% in the counseling group (p = 0.040). The SF-36 physical function, physical role, bodily pain, vitality and emotional role increased by 5.5%, 11.3%, 10.8%, 9.6% and 8.9%, respectively, in the exercise group, whereas these only increased by 0.6%, decreased by 0.7% and increased by 1.4%, 3.8% and 0.6% in the counseling group (all p < 0.05). CONCLUSIONS: Our results suggest that a 16-week concurrent exercise program adapted for midlife women improved their health-related quality of life. CLINICALTRIALS.GOV IDENTIFIER: NCT02358109.

Longitudinal health-related quality of life analysis in childhood cancer survivors after proton beam therapy.

PURPOSE: Whilst proton beam therapy (PBT) for children with cancer is expected to reduce their comorbidities, to date only a limited number of studies have been published. To analyze the long-term comorbidity and health-related quality of life (HRQoL) of childhood cancer survivors (CCSs) after PBT, we conducted a questionnaire-based study. METHODS: Questionnaires were sent to CCSs who underwent PBT at the University of Tsukuba Hospital during the period from 1984 to 2020. Scores from 41 CCSs who did not undergo PBT (noPBT-CCSs) and from the general population were used for comparison. RESULTS: In total, 110 individuals who underwent PBT participated in the study. Among them, 40 individuals were longitudinally analyzed. The range of change in the scores was significantly greater in the CCSs whose initial scores were low. Although the comorbidity levels were more severe, HRQoL tended to be better in the PBT-CCSs than in the noPBT-CCSs with central nervous system (CNS) or solid tumors, respectively. When compared with the general population, the psychosocial health summary scores and its components were not different in the noPBT-CNS-CCSs. On the other hand, the psychosocial health summary scores and/or at least one of the scores of emotional, social, and school functioning were significantly higher in the other CCSs groups. CONCLUSIONS: The HRQoL scores of CCSs with low initial scores can be greatly changed over time. Appropriate psychosocial support for this population is warranted. PBT may avoid reduction in HRQoL in terms of the psychosocial functioning of CCSs with CNS tumors.

Association of physical activity, smoking, and socioeconomic factors on health checkup participation in community-dwelling stroke survivors aged 50 years or older.

BACKGROUND: We investigated the sociodemographic and health-related factors associated with health checkup participation in community-dwelling stroke survivors. METHODS: Among participants of the Korea National Health and Nutrition Examination Survey, 642 stroke survivors were included. We investigated the sociodemographic, medical, and health-related quality of life factors-evaluated by the EuroQol 5-Dimension Questionnaire (EQ-5D)-associated with participation in any type of health checkup. To explore the associations between multiple variables and health checkup participation, a multivariable complex-sample logistic regression model was used. RESULTS: One-third of the community-dwelling stroke survivors did not receive a health checkup in the past two years. Insufficient physical activity (OR: 0.5, 95% CI: 0.3-0.9), current smoking (OR: 0.4, 95% CI: 0.2-0.8), low education level (OR: 0.5, 95% CI: 0.3-0.9), living alone (OR: 0.5, 95% CI: 0.3-0.998), and no occupation (OR: 0.5, 95% CI: 0.3-0.9) showed independent negative associations with health checkup participation. Among the five EQ-5D dimensions, mobility, self-care, usual activities, and pain/discomfort dimensions were associated with health checkup participation rate. CONCLUSION: Policies and further research are needed to promote health checkups for stroke survivors who are physically inactive, currently smoking, living alone, unemployed, less educated, or having extreme problems in their daily lives.

Feasibility and applicability of locomotive syndrome risk test in elderly patients who underwent total knee arthroplasty.

OBJECTIVES: The concept of locomotive syndrome (LS) and its evaluation method, the LS risk test, have been applied in an integrated manner to capture the decline in mobility resulting from musculoskeletal disorders. The purpose of this study was to evaluate the impact of total knee arthroplasty (TKA) in the elderly with knee osteoarthritis, a common disorder found in LS. METHODS: A total of 111 patients were registered prior to TKA and postoperatively followed up for 1 year. Three components of the LS risk test (the two-step test, stand-up test, and Geriatric Locomotive Function Scale-25) were assessed pre- and postoperatively. RESULTS: After surgery, all three components of the test showed significant improvements from the baseline. The ratio of Stage 3 LS patients (progressed stage of decrease in mobility) reduced from 82.3% to 33.9% postoperatively. There was no significant difference in the degree of change in the scores between the younger (60-74 years) and older (≥75 years) age groups. CONCLUSIONS: We found that TKA has a major impact in preventing the progression of LS in patients with knee osteoarthritis. The LS risk test is a feasible tool for the longitudinal evaluation of patients with musculoskeletal diseases of varying severity and with multiple symptoms.

[Comparison Between EuroQol Five-Dimensional Questionnaire and Short-Form 6-Dimension Health Survey for the Populations in China:A Scoping Review].

Objective By review of the studies comparing the measurements properties of EuroQol five-dimensional questionnaire (EQ-5D) and short-form 6-dimension health survey (SF-6D) in Chinese populations,this study aims to provide a reference for selecting,applying,and improving the health-related quality of life and health utility measurement tools for Chinese populations.Methods We retrieved the original studies which compared the two tools from both Chinese and English databases and then summarized the findings of the included studies from the measurement properties.Results A total of 12 studies were screened out,including 9 studies about diseased populations and 3 studies about the general populations.The included studies generally demonstrated that both EQ-5D and SF-6D had good feasibility,while the utility scores generated from them cannot be used interchangeably.For the diseased populations,both EQ-5D and SF-6D and their utility scores had good construct validity,including convergent and known-groups validity,while only the utility scores had good construct validity for the general populations.For the diseased populations,SF-6D had smaller ceiling effect and better sensitivity than EQ-5D-3L,while the comparison results between SF-6D and EQ-5D-5L were inconsistent.For the general populations,SF-6D also had better sensitivity than EQ-5D.In addition,there was little comparative evidence for reliability such as test-retest reliability and responsiveness between SF-6D and SF-6D in the two populations.Conclusion This review summarized the characteristics,methods,results,and conclusions of the studies that directly compared the two tools for the populations in China.Although only the studies directly comparing EQ-5D and SF-6D are included in this review,the common findings in these studies provide a basis for better comparison between the two in the future.

A Comparison of a Preliminary Version of the EQ-HWB Short and the 5-Level Version EQ-5D.

OBJECTIVES: The EQ Health and Wellbeing Short (EQ-HWB-S) is a new broad generic measure of health and wellbeing for use in economic evaluations of interventions across healthcare, social care, and public health. This measure conceptually overlaps with the 5-level version EQ-5D (EQ-5D-5L), while expanding on the coverage of health and social care related dimensions. This study aims to examine the extent to which the EQ-HWB-S and EQ-5D-5L overlap and are different. METHODS: A sample of US-based respondents (n = 903; n = 400 cancer survivors and n = 503 general population) completed a survey administered via an online panel. The survey included the EQ-HWB item pool (62 items, including 11 items used in this analysis), EQ-5D-5L, and questions about sociodemographic and health characteristics. The analysis included (Spearman's) correlations, the comparison of patterns of response (distributions and ceiling effects), and the ability to discriminate between known groups. RESULTS: Moderate to strong associations were found between conceptually overlapping dimensions of the EQ-5D-5L and the EQ-HWB-S (rs > 0.5, P < .001). Among respondents reporting full health on the EQ-5D-5L (n = 161, 18.23%), the EQ-HWB-S identified ceiling effects, particularly with the item "feeling exhausted." Most EQ-5D-5L and EQ-HWB-S items demonstrated discriminative ability among those with and without physical and mental conditions, yielding medium (> 0.5) to large effect sizes (> 0.8). Nevertheless, only EQ-HWB-S items distinguished between caregivers and noncaregivers and those with low and high caregiver burden, albeit with small effect sizes (0.2-0.5). CONCLUSIONS: Results indicate a convergence between the measures, especially between overlapping dimensions, lending support to the validity of the EQ-HWB-S. The EQ-HWB-S performed similarly or better than the EQ-5D-5L among patient groups and is better able to differentiate among caregivers and respondents closer to full health.

Quality of Life Assessment in Trials of Revascularization for Chronic Stable Angina: Insights from ORBITA and the Implications of Blinding.

The main aims of therapy in chronic stable angina are to reduce the risk of myocardial infarction and death and improve symptoms and quality of life (QoL). Unblinded trials have shown that revascularization does not reduce the risk of myocardial infarction or death but does appear to improve symptoms. However, symptoms are susceptible to the placebo effect which can bias therapies to appear more effective than they are. To assess the true physical impact of a treatment on symptoms, placebo-controlled trials with patients and medical and research teams blinded to treatment allocation are necessary. Symptoms and QoL can be reported directly by the patient or indirectly by the physician. Patient-reported outcome measures in angina trials can include angina frequency, frequency of nitrate use, exercise capacity, and questionnaires such as the Seattle Angina Questionnaire (SAQ) and the generic EuroQOL-5D-5L (EQ-5D-5L) QoL questionnaire. Physician-assessed outcome measures include Canadian Cardiovascular Society Class. The Objective Randomised Blinded Investigation with Optimal Medical Therapy of Angioplasty in Stable Angina (ORBITA) trial was the first blinded placebo-controlled study investigating the role of percutaneous coronary intervention (PCI) in chronic stable angina. The trial showed a smaller than expected and not statistically significant effect of placebo-controlled PCI on the primary endpoint of change in exercise time at 6 weeks follow-up in single-vessel coronary artery disease. There was also no significant placebo-controlled treatment effect of PCI for the prespecified secondary endpoints of SAQ or EQ-5D-5L, although PCI did result in 20% more patients becoming free from angina than placebo in a non-prespecified secondary analysis. ORBITA has demonstrated the need for symptomatic and QoL effects of PCI to be studied using placebo control. Here, we describe ways of measuring QoL, the impact of the unblinded and blinded trials to date, what we have learned from ORBITA, and what is next for this common and complex condition.

Postoperative outcomes after degenerative lumbar spine surgery in rheumatoid arthritis patients -a propensity score-matched analysis.

BACKGROUND: Although treatment options for rheumatoid arthritis (RA) have evolved significantly since the introduction of biologic agents, degenerative lumbar disease in RA patients remains a major challenge. Well-controlled comparisons between RA patients and their non-RA counterparts have not yet been reported. The objective of the present study was to compare postoperative outcomes of lumbar spine surgery between RA and non-RA patients by a retrospective propensity score-matched analysis. METHODS: Patients who underwent primary posterior spine surgery for degenerative lumbar disease in our prospective multicenter study group between 2017 and 2020 were enrolled. Demographic data including age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) physical status classification, diabetes mellitus, smoking, steroid usage, number of spinal levels involved, and preoperative patient-reported outcome (PRO) scores (numerical rating scale [NRS] for back pain and leg pain, Short Form-12 physical component summary [PCS], EuroQOL 5-dimension [EQ-5D], and Oswestry Disability Index [ODI]) were used to calculate a propensity score for RA diagnosis. One-to-one matching was performed and 1-year postoperative outcomes were compared between groups. RESULTS: Among the 4567 patients included, 90 had RA (2.0%). RA patients in our cohort were more likely to be female, with lower BMI, higher ASA grade and lower current smoking rate than non-RA patients. Preoperative NRS scores for leg pain, PCS, EQ-5D, and ODI were worse in RA patients. Propensity score matching generated 61 pairs of RA and non-RA patients who underwent posterior lumbar surgery. After background adjustment, RA patients reported worse postoperative PCS (28.4 vs. 37.2, p = 0.008) and EQ-5D (0.640 vs. 0.738, p = 0.03), although these differences were not significant between RA and non-RA patients not on steroids. CONCLUSIONS: RA patients showed worse postoperative quality of life outcomes after posterior surgery for degenerative lumbar disease, while steroid-independent RA cases showed equivalent outcomes to non-RA patients.
