Comparison of trends in US health-related quality of life over the 2000s using the SF-6D, HALex, EQ-5D, and EQ-5D visual analog scale versus a broader set of symptoms and impairments

Cumulative social disadvantage and health-related quality of life: national health interview survey 2013-2017

BACKGROUND

Evidence for the association between social determinants of health (SDoH) and health-related quality of life (HRQoL) is largely based on single SDoH measures, with limited evaluation of cumulative social disadvantage. We examined the association between cumulative social disadvantage and the Health and Activity Limitation Index (HALex).

METHODS

Using adult data from the National Health Interview Survey (2013-2017), we created a cumulative disadvantage index by aggregating 47 deprivations across 6 SDoH domains. Respondents were ranked using cumulative SDoH index quartiles (SDoH-Q1 to Q4), with higher quartile groups being more disadvantaged. We used two-part models for continuous HALex scores and logistic regression for poor HALex (< 20th percentile score) to examine HALex differences associated with cumulative disadvantage. Lower HALex scores implied poorer HRQoL performance.

RESULTS

The study sample included 156,182 respondents, representing 232.8 million adults in the United States (mean age 46 years; 51.7% women). The mean HALex score was 0.85 and 17.7% had poor HALex. Higher SDoH quartile groups had poorer HALex performance (lower scores and increased prevalence of poor HALex). A unit increase in SDoH index was associated with - 0.010 (95% CI [-0.011, -0.010]) difference in HALex score and 20% higher odds of poor HALex (odds ratio, OR = 1.20; 95% CI [1.19, 1.21]). Relative to SDoH-Q1, SDoH-Q4 was associated with HALex score difference of -0.086 (95% CI [-0.089, -0.083]) and OR = 5.32 (95% CI [4.97, 5.70]) for poor HALex. Despite a higher burden of cumulative social disadvantage, Hispanics had a weaker SDoH-HALex association than their non-Hispanic White counterparts.

CONCLUSIONS

Cumulative social disadvantage was associated with poorer HALex performance in an incremental fashion. Innovations to incorporate SDoH-screening tools into clinical decision systems must continue in order to accurately identify socially vulnerable groups in need of both clinical risk mitigation and social support. To maximize health returns, policies can be tailored through community partnerships to address systemic barriers that exist within distinct sociodemographic groups, as well as demographic differences in health perception and healthcare experience.

The trend in quality of life of Chinese population: analysis based on population health surveys from 2008 to 2020

BACKGROUND

Quality of life (QoL) is one of the most important indicators for evaluating an individual's overall health status. However, evidence exploring the trend in QoL of the Chinese population is still lacking. This study aimed to investigate the trend in QoL of the Chinese population measured by the EQ-5D from 2008 to 2020, as well as compare the changing trends in QoL categorized by populations with different socio-demographic characteristics.

METHODS

Data were obtained from the 2008, 2013, and 2020 waves of the Health Services Surveys conducted in Tianjin, China. Respondents completed the EQ-5D (EQ-5D-3L in 2008 and 2013 and EQ-5D-5L in 2020) through face-to-face interviews or self-administration. Responses of the EQ-5D-3L in 2008 and 2013 were mapped onto the EQ-5D-5L responses, and then converted to utility values using the Chinese value set. The trend in QoL was explored by comparing the percentage of any reported problems on each EQ-5D dimension and the corresponding utility values across the three waves. Subgroup analyses were performed to compare trends in utility values stratified by socio-demographic indicators. The effect of the time variable (year) on utility values was assessed by multiple linear regression analyses using the pooled data.

RESULTS

By analyzing and comparing the three waves of the data (N = 25,939 in the 2008 wave, N = 22,138 in 2013, and N = 19,177 in 2020), an upward trend was observed in the percentages of reporting problems on all five dimensions (p < 0.001), resulting in a decreasing trend in utility values (2008: 0.948, 2013: 0.942, 2020: 0.939, p < 0.001). Utility values declined more over time among the female, the elder, the recipients of medical assistance, the widowed, the unemployed, and respondents with primary or lower education. The effect of the year (Coef. for 2013 = - 0.009, p < 0.001; Coef. for 2020 = - 0.010, p < 0.001) confirmed the downward trend in the utility values.

CONCLUSIONS

The overall QoL of the Chinese population decreased over the period from 2008 to 2020. The QoL of the disadvantaged or vulnerable populations in terms of socioeconomic characteristics declined more over time.

Establishing the minimal clinically important difference of the EQ-5D-3L in older adults with a history of falls

PURPOSE

Establish the minimal clinically important difference (MCID) of a health-related quality of life (HRQoL) measure-the EuroQol EQ-5 Dimensions-3 Level (EQ-5D-3L)-in older adults with a history of falls.

METHODS

This study is a secondary analysis of 255 complete cases who were enrolled in a 12-month randomized controlled trial (NCT01029171; NCT00323596); participants were randomized to the Otago Exercise Program (OEP; n = 126/172; Age:81.2 ± 6.2 years; 60.3% Female) or control (CON; n = 129/172; Age:81.7 ± 5.7 years; 70.5% Female). Participants completed the EQ-5D-3L and Visual Analogue Scale (VAS) at baseline and 1-year. The VAS was associated with HRQoL and was the health status anchor (VAS minimal improvement = 7 to 17, maximal improvement ≥ 18, minimal decline =  - 7 to - 17, maximal decline ≤  - 18 points). We used four distinct approaches to estimate MCID ranges: (1) anchor-based change differences of the EQ-5D-3L (1-year minus baseline); (2) anchor-based beta coefficients from ordinary least squares regressions (OLS); (3) anchor-based receiver operating characteristic (ROC), and 4) distribution-based standard deviation and standardized effect size of 0.5.

RESULTS

EQ-5D-3L MCID ranges for minimal improvements (OEP = 0.028 to 0.059; CON = 0.007 to 0.051), maximal improvements (OEP = 0.059 to 0.090; CON = 0.051 to 0.090), minimal declines (OEP =  - 0.029 to - 0.105; CON =  - 0.015 to - 0.051), and maximal declines (OEP =  - 0.018 to - 0.072; CON =  - 0.018 to - 0.082) were established using change difference, OLS, and distribution-based methods. The ROC area under the curve was poor, thus, it was not used to estimate the MCID.

CONCLUSIONS

Our results will assist in the interpretation of changes in HRQoL, as measured by the EQ-5D-3L, in older adults with a history of falls.

Effectiveness of music therapy for alleviating pain during haemodialysis access cannulation for patients undergoing haemodialysis: a multi-facility, single-blind, randomised controlled trial

Background

Repeated pain during haemodialysis access cannulations is a serious problem for haemodialysis patients even when prescribed oral or topical analgesics. Although some studies have observed the efficacy of music therapy for improving pain and anxiety, its effectiveness during haemodialysis access cannulations during dialysis is uncertain. The purpose of this study is to investigate the effects of music therapy for pain when cannulating haemodialysis access for haemodialysis patients.

Methods

A prospective, multi-facility, single-blind, crossover, randomised controlled trial will be implemented. The intervention includes listening to Mozart, along with a white noise control condition. One hundred twenty haemodialysis patients will be enrolled across five facilities. Patients will be randomly allocated to either an Early-sequence group or a Later-sequence group. The Early-sequence group will receive cannulation while listening to Mozart’s Sonata for two pianos in D major (K.448) during the second week (Music period) and white noise during the fourth week (White noise period). The Later-sequence group will receive cannulation along with white noise first, followed by Mozart. All patients will also undergo cannulation during a no-sound period (wearing only headphones) during the first and third week (No-sound period). The music or no-music protocol will begin 8 min prior to the cannulating procedure, and participants will finish listening after starting haemodialysis during each period. The primary outcomes that will be assessed include the Visual Analogue Scale (VAS) score for pain during cannulation, and secondary outcomes are blood pressure, heart rate, VAS anxiety score, State-Trait Anxiety Inventory score, and salivary amylase activity. The operators who are in charge of haemodialysis access cannulation will be blind to the listening condition and VAS report.

Discussion

The proposed study has several methodological benefits. First, using white noise is a suitable control condition for addressing the role of sound in pain management. Additionally, using a crossover design with repeated measurements can help control individual differences between participants, which should better distinguish between- and within-participant variability. Overall, music therapy is a safe and inexpensive intervention that does not have the problematic side effects typically associated with pharmacological treatment. If effective, music therapy can be easily implemented for reducing pain and anxiety during cannulation.

Long-term effect of community-based continence promotion on urinary symptoms, falls and healthy active life expectancy among older women: cluster randomised trial

Background

The long-term effectiveness of group continence promotion delivered via community organisations on female urinary incontinence, falls and healthy life expectancy remains unknown.

Methods

A pragmatic cluster randomised trial was conducted among 909 women aged 65–98 years with urinary incontinence, recruited from 377 community organisations in the UK, Canada and France. A total of 184 organisations were randomised to an in-person 60-min incontinence self-management workshop (461 participants), and 193 to a control healthy ageing workshop (448 participants). The primary outcome was self-reported incontinence improvement at 1-year. Falls and gains in health utility were secondary outcomes.

Results

A total 751 women, mean age 78.0, age range 65–98 completed the trial (83%). At 1-year, 15% of the intervention group versus 6.9% of controls reported significant improvements in urinary symptoms, (difference 8.1%, 95% confidence intervals (CI) 4.0–12.1%, intracluster correlation 0.04, number-needed-to-treat 13) and 35% versus 19% reported any improvement (risk difference 16.0%, 95% CI 10.4–21.5, number-needed-to-treat 6). The proportion of fallers decreased from 42% to 36% in the intervention group (−8.0%, 95% CI −14.8 – −1.0) and from 44% to 34% in the control group (−10.3%, 95% CI −17.4 – −3.6), no difference between groups. Both intervention and control groups experienced a gain in health utility (0.022 points (95% CI 0.005–0.04) versus 0.035 (95% CI 0.017–0.052), respectively), with no significant difference between groups.

Conclusion

Community-based group continence promotion achieves long-term benefits on older women’s urinary symptoms, without improvement in falls or healthy life expectancy compared with participation in a healthy ageing workshop.

Comparison of the EQ-5D 3L and the SF-6D (SF-36) contemporaneous utility scores in patients with chronic kidney disease in Sri Lanka: a cross-sectional survey

OBJECTIVES

The aim of this study was to compare utility weights of EuroQoL-five-dimension-3 levels (EQ-5D-3L) and Short-Form six-dimension (SF-6D) in a representative cohort of patients with chronic kidney disease (CKD). A cost-utility analysis (CUA) is designed to report the change to costs required to achieve an estimated change to quality-adjusted life years (QALYs). The quality component of a QALY is measured by utility. Utility represents the preference of general population for a given health state. Classification systems of the multi-attribute utility instruments (MAUIs) are used to define these health states. Utility weights developed from different classification systems can vary and may affect the conclusions from CUAs.

DESIGN

A community-based cross-sectional study.

SETTING

Anuradhapura, a rural district in Sri Lanka.

PARTICIPANTS

A representative sample of 1096 patients with CKD, selected using the population-based CKD register, completed the EQ-5D-3L and SF-36. SF-6D was constructed from the SF-36 according to the published algorithm. The study assessed discrimination, correlation and differences across the two instruments.

RESULTS

Study participants were predominantly male (62.6%). Mean EQ-5D-3L utility score was 0.540 (SD 0.35) compared with 0.534 (SD 0.09) for the SF-6D (p=0.588). The correlation (r) between the scores was 0.40 (p<0.001). Utility scores were significantly different in both males and females between the two tools, but there was no difference in age and educational categories. Both MAUI scores were significantly lower (p<0.001) among those who were in more advanced stages of the disease and the corresponding utility scores of the two instruments in different CKD stages were also significantly different (p<0.05). The largest effect size was seen among the patients on dialysis.

CONCLUSIONS

The correlation between the scores was moderate. SF-6D had the lowest floor and ceiling effect and was better at detecting different stages of the disease. Thus, based on the evidence presented in this study, SF-6D appears to be more appropriate to be used among patients with CKD.

Analgesic effect of preoperative dezocine-based local anesthesia in patients undergoing inguinal hernia repair

Objective

This study was performed to investigate the analgesic effects of intramuscular injection of dezocine-based local anesthesia in patients undergoing inguinal hernia repair.

Methods

A total of 120 patients underwent local herniorrhaphy from July 2015 to December 2016 and were randomly divided into 2 groups: the dezocine group, in which a preoperative intramuscular injection of dezocine was administered, and the control group, in which no dezocine injection was administered. The patients’ pain and comfort levels were evaluated at 30 minutes, 2 hours, 6 hours, 12 hours, and 24 hours postoperatively.

Results

The visual analog scale scores at 30 minutes, 2 hours, 6 hours, 12 hours, and 24 hours were significantly lower in the dezocine than control group. In the Bruggemann comfort scale evaluation, patients who received dezocine injections showed significantly greater comfort than those in the control group at 30 minutes, 2 hours, 6 hours, 12 hours, and 24 hours. No adverse reactions occurred in the dezocine group.

Conclusions

Dezocine-based local anesthesia can attenuate postoperative pain and increase the comfort level during and after herniorrhaphy.

Physical activity and body mass shape quality of life trajectories in mid-age women

OBJECTIVE

To determine the combined longitudinal effect of body mass index (BMI) and physical activity (PA) on health-related quality of life (HrQoL), using the SF-6D (SF-36) utility measure.

METHODS

Five waves of self-reported data from the 1946-51 cohort (n=5,200; data collection, 2001-2013) of the Australian Longitudinal Study on Women's Health were used. Mixed effect models were employed to address the objective.

RESULTS

Women with high PA experienced higher HrQoL regardless of BMI group, however, for those healthy or overweight, there was a very small decline in HrQoL over time. Women reporting no PA levels experienced the lowest baseline mean SF-6D score within each BMI group, with decreasing trajectories over the follow-up period. The rate of decline was greatest in women with obesity. Within each BMI group, there was a large, increasing gap in HrQoL between those who reported no and low PA over time. Women with obesity and high PA experienced similar HrQoL trajectories to women with normal weight or overweight with low PA levels. Overweight women with moderate PA experienced similar HrQoL to those with low PA but normal weight.

CONCLUSIONS

PA may mitigate the adverse effect of overweight and obesity on HrQoL at mid-life, at higher activity levels. Implications for public health: PA benefits HrQoL regardless of body mass, with larger gains for those currently not physically active. Moderate to high PA may mitigate the effect of overweight and obesity.

Assessing the impact of caring for a child with Dravet syndrome: Results of a caregiver survey

OBJECTIVE

The objective of this study was to describe and quantify the impact of caring for a child with Dravet syndrome (DS) on caregivers.

METHODS

We surveyed DS caregivers at a single institution with a large population of patient with DS. Survey domains included time spent/difficulty performing caregiving tasks (Oberst Caregiving Burden Scale, OCBS); caregiver health-related quality of life (EuroQoL 5D-5L, EQ-5D); and work/activity impairment (Work Productivity and Activity Impairment questionnaire, WPAI). Modified National Health Interview Survey (NHIS) questions were included to assess logistical challenges associated with coordinating medical care.

RESULTS

Thirty-four primary caregivers responded, and 30/34 respondents completed the survey. From OCBS, providing transportation, personal care, and additional household tasks required the greatest caregiver time commitment; arranging for child care, communication, and managing behavioral problems presented the greatest difficulty. EuroQoL 5D-5L domains with the greatest impact on caregivers (0=none, 5=unable/extreme) were anxiety/depression (70% of respondents≥slight problems, 34%≥moderate) and discomfort/pain (57% of respondents≥slight problems, 23%≥moderate). The mean EQ-5D general health visual analogue scale (VAS) score (0=death; 100=perfect health) was 67 (range, 11-94). Respondents who scored <65 were two- to fourfold more likely to report ≥moderate time spent and difficulty managing child behavior problems and assisting with walking, suggesting that children with DS with high degrees of motor or neurodevelopmental problems have an especially high impact on caregiver health. On the WPAI, 26% of caregivers missed >1day of work in the previous week, with 43% reporting substantial impact (≥6, scale=1-10) on work productivity; 65% reported switching jobs, quitting jobs, or losing a job due to caregiving responsibilities. National Health Interview Survey responses indicated logistical burdens beyond the home; 50% of caregivers made ≥10 outpatient visits in the past year with their child with DS.

CONCLUSIONS

Caring for patients with DS exerts physical, emotional, and time burdens on caregivers. Supportive services for DS families are identified to highlight an unmet need for DS treatments.

Health-Related Utility Weights in a Cohort of Real-World Crohn's Disease Patients

BACKGROUND AND AIMS

Estimating health-related utility weights in Crohn's Disease [CD] patients is crucial for assessing the cost-effectiveness of new pharmaceutical interventions. Values used in most analyses are based on secondary data and vary substantially among studies. We estimated utility weights in a consecutive sample of real-world CD patients.

METHODS

Patients enrolled in an ongoing socioeconomic study of CD in the Israeli adult patient population completed a self-administered Short Form 36 health survey [SF-36] and Short Inflammatory Bowel Disease [SIBDQ] questionnaires and were assessed for their current clinical status, including the Harvey-Bradshaw Index [HBI] of disease severity. For each patient enrolled we calculated a utility weight using the SF-6D scoring system.

RESULTS

The cohort comprised 425 patients [40% male] with mean age of 39.1 [± 14.0] years. The average HBI was 6.1 [± 5.4]; 198 [47%] patients were in remission state [HBI < 5], 99 [23%] had mild disease [HBI 5-7], 102 [25%] moderate [HBI 8-16], and 26 [6%] severe disease [HBI > 16]. Mean utility weights were: 0.667 in all patients, 0.744 in patients with disease remission, 0.638 in mild disease, 0.587 in moderate disease, and 0.505 in severe disease. The significant predictors of utility weights in a multivariable regression analysis were the HBI [β = -0.494; p < 0.001], economic status [β = 0.198; p < 0.001], time since diagnosis [β = 0.106; p < 0.001], male [compared with female] gender [β = 0.099; p = 0.009], hospital admission in the past year for any cause [β = -0.086; p = 0.027], and treatment with steroids [β = -0.100; p = 0.012] where β denotes the standardised regression coefficients; model adjusted R(2) = 0.428.

CONCLUSIONS

Utility weights for patients in the remission and mild disease states were generally lower as compared with values used in published cost-effectiveness analyses. These values should be considered when assessing the value for money of future interventions for CD.

Improving quality of care and long-term health outcomes through continuity of care with the use of an electronic or paper patient-held portable health file (COMMUNICATE): study protocol for a randomized controlled trial

BACKGROUND

The advantages of patient-held portable health files (PHF) and personal health records (PHR), paper or electronic, are said to include improved health-care provider continuity-of-care and patient empowerment in maintaining health. Top-down approaches are favored by public sector government and health managers. Bottom-up approaches include systems developed directly by health-care providers, consumers and industry, implemented locally on devices carried by patient-consumers or shared via web-based portals. These allow individuals to access, manage and share their health information, and that of others for whom they are authorized, in a private, secure and confidential environment. Few medical record technologies have been evaluated in randomized trials to determine whether there are important clinical benefits of these interventions. The COMMUNICATE trial will assess the acceptability and long-term clinical outcomes of an electronic and paper patient-held PHF.

METHODS/DESIGN

This is a 48-month, open-label pragmatic, superiority, parallel-group design randomized controlled trial. Subjects (n = 792) will be randomized in a 1:1:1 ratio to each of the trial arms: the electronic PHF added to usual care, the paper PHF added to usual care and usual care alone (no PHF). Inclusion criteria include those 60 years or older living independently in the community, but who have two or more chronic medical conditions that require prescription medication and regular care by at least three medical practitioners (general and specialist care). The primary objective is whether use of a PHF compared to usual care reduces a combined endpoint of deaths, overnight hospitalizations and blindly adjudicated serious out-of-hospital events. All primary analyses will be undertaken masked to randomized arm allocation using intention-to-treat principles. Secondary outcomes include quality of life and health literacy improvements.

DISCUSSION

Lack of blinding creates potential for bias in trial conduct and ascertainment of clinical outcomes. Mechanisms are provided to reduce bias, including balanced study contact with all participants, a blinded adjudication committee determining which out-of-hospital events are serious and endpoints that are objective (overnight hospitalizations and mortality). The PRECIS tool provides a summary of the trial's design on the Pragmatic-Explanatory Continuum.
