[PMID: 39300432 DOI: 10.1186/s12955-024-02297-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 09/09/2024] [Indexed: 09/22/2024] Open
Abstract
BACKGROUND This study evaluates the health-related quality of life (HRQoL) of persons with diffuse large B-cell lymphoma (DLBCL) by using EQ-5D-5L and SF-6Dv2 and compares the measurement properties of the two instruments. METHOD DLBCL patients were identified via a patient group and were surveyed using web-based questionnaires. Demographic information, socioeconomic status (SES), clinical characteristics, and EQ-5D-5L and SF-6Dv2 responses were collected and statistically described. The association between the EQ-5D-5L and SF-6Dv2 dimensions were analyzed using the Spearman's correlation coefficient, whereas the correlation of the utility scores was evaluated using Pearson's correlation coefficient. The agreement between the responses of the two instruments were examined using a Bland-Altman (B-A) plot. A one-way analysis of variance (ANOVA) was performed to compare the utility scores across subgroups in different clinical states (a t-test was used if there were two subgroups). In addition, the graded response model (GRM) was used to describe the discrimination ability and difficulty characteristics of the dimensions in the two instruments. RESULTS In total, 582 valid responses were collected, among which 477 respondents were associated with initial-treatment and 105 respondents were relapsed/refractory (RR) patients. The mean (standard deviation [SD]) EQ-5D-5L and SF-6Dv2 utility scores of the DLBCL patients were 0.828 (0.222) and 0.641 (0.220), respectively. The correlation between the EQ-5D-5L and SF-6Dv2 dimensions ranged from 0.299 to 0.680, and the correlation between their utility scores was 0.787. The B-A plot demonstrated an acceptable but not strong agreement between EQ-5D-5L and SF-6Dv2 utility scores. The GRM model results indicated that all dimensions of each instrument were highly discriminating overall, but EQ-5D-5L had suboptimal discriminative power among patients with good health. CONCLUSION Both the EQ-5D-5L and SF-6Dv2 showed valid properties to assess the HRQoL of DLBCL patients. However, utility scores derived from the two instruments had substantial difference, thereby prohibiting the interchangeable use of utilities from the two instruments.

Rheumatology (Oxford) 2024; 63:1113-1122. [PMID: 37522862 DOI: 10.1093/rheumatology/kead351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 06/10/2023] [Accepted: 06/27/2023] [Indexed: 08/01/2023] Open
Abstract
OBJECTIVE To investigate the health-related quality of life (HR-QoL), work productivity and activity impairment and associated factors among patients with idiopathic inflammatory myopathy (IIM). METHODS This was an observational, cross-sectional study. The 189 ambulatory patients with IIM were recruited from May 2019 to May 2022. HR-QoL was measured by the European Quality of Life 5-Dimension (EQ-5D) questionnaire. The Work Productivity and Activity Impairment (WPAI) questionnaire was used to evaluate work productivity and activity impairment. The IIM-related parameters were assessed by the 8-item Manual Muscle Test (MMT-8), Myositis Disease Activity Assessment visual analogue scale (MYOACT), Myositis Damage Index (MDI), Disease Activity Score (DAS) and Physician/Patient Global Assessment (PhGA/PtGA). Quantile regression and ordinal logistic regression were performed to identify the factors, considering EQ-5D or WPAI scores as dependent variables, respectively. RESULTS Of the 189 IIM patients enrolled, 60% had DM, 13% had PM and 27% had clinical amyopathic DM. The median EQ-5D score was 1.00 (95% CI 0.73, 1.00), 28% were employed and 45% of overall work was impaired due to health problems. EQ-5D values were positively associated with MMT-8 and negatively with MYOACT, DAS, MDI-global and PhGA/PtGA. For the WPAI, activity impairment was associated with a lower MMT-8 score, older onset age and higher PhGA only in 25th-75th percentile. Increased PtGA was associated with increased activity and overall working productivity impairment in most quantiles (P<0.05). CONCLUSION Multiple disease characteristics were associated with reduced HR-QoL or working productivity impairment in patients with IIM, especially for PtGA.

Methods Protoc 2024; 7:24. [PMID: 38525782 PMCID: PMC10961787 DOI: 10.3390/mps7020024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 12/21/2023] [Accepted: 01/01/2024] [Indexed: 03/26/2024] Open
Abstract
Cancer, a pervasive global health challenge, necessitates chemotherapy or radiotherapy treatments for many prevalent forms. However, traditional follow-up approaches encounter limitations, exacerbated by the recent COVID-19 pandemic. Consequently, telemonitoring has emerged as a promising solution, although its clinical implementation lacks comprehensive evidence. This report depicts the methodology of a randomized trial which aims to investigate whether leveraging a smartphone app called Contigo for disease monitoring enhances self-reported quality of life among patients with various solid cancers compared to standard care. Secondary objectives encompass evaluating the app's impact on depressive symptoms and assessing adherence to in-person appointments. Randomization will be performed independently using an allocation sequence that will be kept concealed from clinical investigators. Contigo offers two primary functions: monitoring cancer patients' progress and providing educational content to assist patients in managing common clinical situations related to their disease. The study will assess outcomes such as quality of life changes and depressive symptom development using validated scales, and adherence to in-person appointments. Specific scales include the EuroQol Group's EQ-5D questionnaire and the Patient Health Questionnaire (PHQ-9). We hypothesize that the use of Contigo will assist and empower patients receiving cancer treatment, which will translate to better quality of life scores and a reduced incidence of depressive symptoms. All analyses will be undertaken with the intention-to-treat principle by a statistician unaware of treatment allocation. This trial is registered in ClinicalTrials under the registration number NCT06086990.

Abstract
BACKGROUND The purpose of this study is to examine the relationship between the Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS) and EQ-5D-5L and compare their psychometric properties in 4 chronic conditions in China. METHODS Participants were invited to complete the online survey. Spearman's rank correlation was used to evaluate the correlation between SWEMWBS and EQ-5D-5L; exploratory factor analysis was used to ascertain the number of unique underlying latent factors measured by SWEMWBS and EQ-5D-5L. Next, we assessed the psychometric properties of SWEMWBS and EQ-5D-5L by reporting distributions and examining their known-group validity and convergent validity. RESULTS In total, 500 individuals participated the online survey. Spearman's rank correlation showed that EQ-5D-5L dimensions, except for the anxiety/depression dimension, were weakly correlated with all dimensions of SWEMWBS. The two-factor solution for exploratory factor analysis found that all of SWEMWBS dimensions loaded onto one factor, four EQ-5D-5L dimensions (mobility, self-care, usual activities and pain/discomfort) onto another, and the EQ-5D-5L item of anxiety/depression item loaded moderately onto both factors. Patients of four disease groups had different distributions of responses for both SWEMWBS and EQ-5D-5L. In terms of known-group validity, both the F statistic and AUROC value of EQ-5D-5L utility scores were significantly higher than SWEMWBS scores in all four pair-wised comparisons. The Pearson correlation coefficient between EQ-5D-5L utility scores, SWEMWBS scores and EQ-VAS was 0.44 (P < 0.01) and 0.65 (P < 0.01), respectively. CONCLUSIONS SWEMWBS and EQ-5D-5L measure different constructs and can be seen as complementary measures. Both measures demonstrated good convergent validity and known-group validity with EQ-5D-5L being a more sensitive measure, even for mental conditions.

Abstract
INTRODUCTION Euro-Qol-5 Dimension (EQ-5D) and Short-Form 6-Dimension (SF-6D) are the most commonly used generic multi-attribute utility instruments (MAUI) to calculate quality-adjusted life-years (QALYs) in East and South-East Asia. This study aims to systematically review and summarize current evidence on comparing measurement properties of EQ-5D and SF-6D in East and South-East Asian populations. AREAS COVERED Guided by the PRISMA systematic review and meta-analysis guidelines, a systematic literature search was conducted in databases of PubMed, Web of Science, MEDLINE, EMBASE and CINAHL (until June 2022) to obtain studies which compared measurement properties (feasibility, reliability, validity, responsiveness, and sensitivity) and agreement of EQ-5D and SF-6D in the populations. EXPERT OPINION In general, both EQ-5D and SF-6D had good measurement properties in East and South-East Asian populations; but their utility scores cannot be used interchangeably. Compared to the 3-level EQ-5D, SF-6D had better sensitivity and lower ceiling effects, but the comparison results between the 5-level EQ-5D and SF-6D were inconsistent across populations. This scoping review found that most studies did not consider order effects, did not specify the versions of SF-6D, and ignored certain measurement properties (reliability, content validity, and responsiveness). These aspects need to be further explored in future studies.

Abstract
In Chile, 18% of the population is over 60 years old and is projected to reach 31% in three decades. An aging population demands the development of strategies to improve quality of life (QoL). In this randomized trial, we present the implementation and evaluation of the Quida platform, which consists of a network of unintrusive sensors installed in the houses of elderly participants to monitor their activities and provide assistance. Sixty-nine elderly participants were included. A significant increase in overall QoL was observed amongst participants allocated to the interventional arm (p < 0.02). While some studies point out difficulties monitoring users at home, Quida demonstrates that it is possible to detect presence and movement to identify patterns of behavior in the sample studied, allowing us to visualize the behavior of older adults at different time intervals to support their medical evaluation.

Abstract
BACKGROUND Idiopathic normal pressure hydrocephalus (iNPH) is a potentially reversible disease. Surgical results have been well described in the literature, but only a few studies investigated the subjective outcome. This study aimed to investigate the patient's expectations about surgery, the perceived improvement after treatment, and its impact on the quality of life (QoL). METHODS A new dedicated survey was created to investigate subjectively different aspects of the treatment pathway of iNPH (diagnosis, symptoms, expectations from surgery, surgical operation, surgical results, and postoperative QoL), together with the SF-12 and EQ-5D as validated, standardized tools. RESULTS Forty-five patients were included. Forty-three percent of cases received the diagnosis after at least 1 year, with symptoms worsening in 73%, and frustration in 93%. Reaching a diagnosis was important for 100% of patients, with high expectations from surgery; 86% of them hoped to return to a normal life. Seventy-two percent of patients reported a significant postoperative improvement (walking 68%, mood 57%). Memory and incontinence did not improve in 64% of cases. Subjectively, QoL improved in 72% of cases. The SF-12 score is comparable to controls >75 years, but lower than the 65-75 years group. The EQ-5D index was 0.66 (lower than those of the 65-75 years group = 0.823, and >75 years group = 0.724). Pain and discomfort, instead, were lower compared to the healthy population (43% vs 56%). The idea of having an implanted device and of long-term follow-up is not worrying for 80% of patients; approximately two-thirds of them reported a regained control of their lives. CONCLUSIONS The importance of early diagnosis and patients' perspective, alongside clinical evaluation, is highlighted. The self-reported evaluations on symptoms and QoL, along with the balance between postoperative worries and benefits, should be discussed preoperatively with patients and relatives, and included postoperatively to comprehensively assess the surgical outcome.

[PMID: 35710429 PMCID: PMC9202323 DOI: 10.1186/s12955-022-02003-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Accepted: 06/04/2022] [Indexed: 03/07/2023] Open
Abstract
BACKGROUND SF-6Dv2, the latest version of SF-6D, has been developed recently, and its measurement properties remain to be evaluated and compared with the EQ-5D-5L. The aim of this study was to assess and compare the measurement properties of the SF-6Dv2 and the EQ-5D-5L in a large-sample health survey among the Chinese population. METHODS Data were obtained from the 2020 Health Service Survey in Tianjin, China. Respondents were randomly selected and invited to complete both the EQ-5D-5L and SF-6Dv2 through face-to-face interviews or self-administration. Health utility values were calculated by the Chinese value sets for the two measures. Ceiling and floor effects were firstly evaluated. Convergent validity and discriminate validity were examined using Spearman's rank correlation and effect sizes, respectively. The agreement was assessed using intraclass correlation coefficients (ICC). Sensitivity was compared using relative efficiency and receiver operating characteristic. RESULTS Among 19,177 respondents (49.3% male, mean age 55.2 years, ranged 18-102 years) included in this study, the mean utility was 0.939 (0.168) for EQ-5D-5L and 0.872 (0.184) for SF-6Dv2. A higher ceiling effect was observed in EQ-5D-5L than in SF-6Dv2 (72.8% vs. 36.1%). The Spearman's rank correlation (range: 0.30-0.69) indicated an acceptable convergent validity between the dimensions of EQ-5D-5L and SF-6Dv2. The SF-6Dv2 showed slightly better discriminative capacities than the EQ-5D-5L (ES: 0.126-2.675 vs. 0.061-2.256). The ICC between the EQ-5D-5L and SF-6Dv2 utility values of the total sample was 0.780 (p < 0.05). The SF-6Dv2 had 29.0-179.2% higher efficiency than the EQ-5D-5L at distinguishing between respondents with different external health indicators, while the EQ-5D-5L was found to be 8.2% more efficient at detecting differences in self-reported health status than the SF-6Dv2. CONCLUSIONS Both the SF-6Dv2 and EQ-5D-5L have been demonstrated to be comparably valid and sensitive when used in Chinese population health surveys. The two measures may not be interchangeable given the moderate ICC and the systematic difference in utility values between the SF-6Dv2 and EQ-5D-5L. Further research is warranted to compare the test-retest reliability and responsiveness.

Abstract
AIMS This study compared the psychometric properties of EQ-5D-5L and SF-6D to assess the interchangeability of both instruments in patients with a recent fracture presenting at a Fracture Liaison Service (FLS). MATERIALS AND METHODS Data from a prospective observational study in a Dutch FLS clinic were used. Over 3 years, subjects were interviewed at several time points using EQ-5D-5L and SF-36. Floor and ceiling effects were evaluated. Agreement was evaluated by intra-class correlation coefficients and visualized in Bland-Altman plots. Spearman's rank correlation coefficients were applied to assess convergent validity. Mann-Whitney U test or Kruskal-Wallis H test as well as effect size (ES) were used to explore known-groups validity. Responsiveness was explored using standardized response mean (SRM) and ES. For each measurement property, hypotheses on direction and magnitude of effects were formulated. RESULTS A total of 499 patients were included. EQ-5D-5L had a considerable ceiling effect in comparison to SF-6D (21 vs. 1.2%). Moderate agreement between the (UK and Dutch) EQ-5D-5L and SF-6D was identified with intra-class correlation coefficients of 0.625 and 0.654, respectively. Bland-Altman plots revealed proportional bias as the differences in utilities between two instruments were highly dependent on the health states. High correlation between instruments was found (UK: rho = 0.758; Dutch: rho = 0.763). EQ-5D-5L and SF-6D utilities showed high correlation with physical component score but low correlation with mental component score of SF-36. Both instruments showed moderate discrimination (ES > 0.5) for subgroup by baseline fracture type, and moderate responsiveness (SRM > 0.5) in patients that sustained a subsequent fracture. CONCLUSION Both EQ-5D-5L and SF-6D appeared to be valid utility instruments in patients with fractures attending the FLS. However, they cannot be used interchangeably given only moderate agreement was identified, and differences in utilities and ceiling effect were revealed. Comparable construct validity and responsiveness were indicated, and neither instrument was found to be clearly superior.

Abstract
Study of the outcome of treatment of shoulder conditions has emphasized subjective evaluation of outcomes including a variety of disease, region, and joint-specific tools. In response to the rapidly rising cost of health care, further interest has been directed to cost-effectiveness and value. Comparison of the outcomes of different shoulder conditions with each other, other musculoskeletal, and nonorthopedic conditions requires more generalized outcome tools, especially when considering cost-effectiveness and utility analysis. The concept of quality of life (QoL) was developed to satisfy this goal, and there are a variety of general health and QoL assessments tools available. The purpose of this study is to review the concept of health-related QoL and discuss health-related QoL measures as they relate to shoulder conditions.
