A systematic review of instruments for measuring outcomes in economic evaluation within aged care

Use of the adult social care outcomes toolkit (ASCOT) in research studies: an international scoping review

PURPOSE

Since the launch of Adult Social Care Outcomes Toolkit (ASCOT) in 2012, there has been increasing interest in use of ASCOT measures in social care research and evaluation, internationally. This scoping review seeks to understand ASCOT use and the methodologies within which the measures have been applied.

METHODS

An international scoping review of studies published between January 2012 and July 2024 that utilized ASCOT, excluding measure development and psychometric studies.

RESULTS

Fifty-five articles (11 protocols) reported use of ASCOT. Most reported cross-sectional studies (n = 19) or randomized controlled trials (n = 15) that explored the effectiveness of policy, interventions or systems. ASCOT measures were also applied in mixed methods and other study designs, including qualitative studies. A few studies applied ASCOT to develop theory or conceptual frameworks that relate to care, including how to understand unmet need.

CONCLUSION

ASCOT measures have been applied, internationally, in a range of ways, with a focus on evaluation studies. Further research is required to explore how ASCOT is used in practice, including care planning. Focus is also needed on ensuring users select the appropriate measure for their study, and widen awareness of adapted versions to support data collection, like ASCOT easy read (ASCOT-ER).

Comorbidities and health-related quality of life among rural older community-dwellers in Vietnam

This study explored the patterns of comorbidities and their impact on health-related quality of life (HRQoL) among elderly individuals living in rural communities in Vietnam. A cross-sectional study was conducted across four communes in Thai Binh province. The demographic characteristics and comorbidities of the participants were evaluated, along with their Euroqol-5 dimensions-5 levels (EQ-5D-5L), using a structured questionnaire supplemented by clinical examinations. A multivariate Tobit regression model was applied to assess the relationship between comorbidities and HRQoL. Results showed that a minority of participants (9.5%) were free of comorbidities. Cataracts were the most common condition (61.0%), followed by osteoarthritis (55.4%), rheumatoid arthritis (46.1%), and dementia (39.0%). The average EQ-5D index was 0.806 (SD =  0.184). Pain/discomfort, difficulties with usual activities, and anxiety/depression contributed most to the reduction in the EQ-5D-5L index. Participants with rheumatoid arthritis (β =  - 0.10; 95% CI =  - 0.13, - 0.07) and postural hypotension (β =  - 0.08; 95% CI =  - 0.14, - 0.02) experienced the greatest decrease in EQ-5D index, followed by those with urinary diseases (β =  - 0.05; 95% CI =  - 0.09, - 0.02) and stroke (β =  - 0.05; 95% CI =  - 0.09, - 0.01). This study highlights the high prevalence of comorbidities among the elderly in rural Vietnam, with arthritis, postural hypotension, urinary diseases, and stroke being most strongly associated with reduced HRQoL. Regular screening and monitoring of comorbidities are vital to identify individuals who would benefit most from healthcare interventions to enhance HRQoL.

Performance indicators on long-term care for older people in 43 high- and middle-income countries: literature review, web search and expert consultation

BACKGROUND

Long-term care (LTC) for older people is an area of focus for many health and social policies in high- and middle-income countries. Performance Indicators are used to provide national and subnational jurisdictions with insights to ensure quality of the provided LTC services for older people. Although LTC systems vary across jurisdictions, there is demand for internationally comparable indicators to support countries in monitoring LTC and facilitate mutual learning. The aim of this study was to provide an overview of indicators currently employed to monitor the performance of LTC systems and services in high- and middle- income countries and describe their key characteristics.

METHODS

A review of the literature in six scientific databases (literature review) and web searches of relevant sites across 43 selected countries (web search) was conducted. We asked country representatives from the Working Party on Health Care Quality and Outcomes of the Organization for Economic Cooperation and Development, where most of these countries are represented, to cross-validate the sources of information found (expert consultation). We then extracted and analysed the data from all obtained sources based on a predetermined set of characteristics.

RESULTS

The search of scientific databases yielded 12,960 records, from which forty papers were selected for inclusion. The scientific literature findings were complemented by 34 grey literature sources. In total, we identified performance indicators being used to monitor LTC systems and services across 29 national and subnational jurisdictions in 24 out of 43 countries. In total, 620 indicators were identified. All jurisdictions used indicators related to institutional LTC and 16 also used indicators on home care. The most frequently monitored structures, processes, and results were pressure ulcers, falls, use of restraints and pain management.

CONCLUSIONS

We identified LTC performance indicators currently being monitored in 29 jurisdictions across 24 countries. Many jurisdictions are monitoring similar structures, processes, and results. This presents an opportunity to develop internationally comparable LTC performance indicators based on existing efforts across countries.

Cognitive interviewing for assessing the content validity of older-person specific outcome measures for quality assessment and economic evaluation: a scoping review

PURPOSE

Older people (aged ≥ 65 years) are significant users of health and social care systems. However, many outcome measures for quality assessment and economic evaluation lack content validation for this population. Cognitive interviews are a key approach for generating content validity evidence. This systematic scoping review aimed to synthesise evidence on cognitive interviewing practices with older adults, including those with cognitive impairment and dementia, to determine the content validity of outcome measures used with these populations in health and social care settings.

METHODS

A search was conducted across five databases, and results were uploaded to Covidence review management software. Two researchers performed screening and data extraction using a custom template. The initial search identified 8814 articles. After removing duplicates and conducting title and abstract screening, 105 articles remained. Full-text screening excluded 86 references, resulting in 19 included articles.

RESULTS

Studies utilised various cognitive interviewing approaches, predominantly concurrent think-aloud combined with verbal probing. Inductive analysis based on Tourangeau's four-stage response model was commonly used for analysing verbal protocol data. Only one in four included studies indicated any allowances to alleviate cognitive burden for older participants. There was limited involvement of older people with cognitive impairment and dementia, but studies including these populations reported several modifications enhancing meaningful inclusion.

Clinical and cost-effectiveness of a home-based health promotion intervention for older people with mild frailty in England: a multicentre, parallel-group, randomised controlled trial

BACKGROUND

Health promotion for people with mild frailty has the potential to improve health outcomes, but such services are scarce in practice. We developed a personalised, home-based, behaviour change, health promotion intervention (HomeHealth) and assessed its clinical effectiveness and cost-effectiveness in maintaining independent functioning in activities of daily living in older adults with mild frailty.

METHODS

This trial was an individual, multicentre, parallel-group, randomised controlled trial done in England. Participants were mainly recruited from general practices in three different areas of England (the London north Thames region, east and north Hertfordshire, and west Yorkshire). Participants were individuals residing in the community who were registered with a general practice, 65 years and older with mild frailty (scoring 5 on the CFS), with a life expectancy of more than 6 months, and with capacity to consent to participate. We excluded adults residing in nursing or care homes, those with moderate-to-severe frailty or with no frailty, those receiving palliative care, and those already case managed (eg, receiving a similar ongoing intervention from the voluntary sector or community service). Eligible participants were randomly assigned 1:1 to either the HomeHealth intervention or to treatment as usual. HomeHealth is a multidomain health promotion intervention delivered by the voluntary sector at home in six sessions over 6 months. The primary outcome was independent functioning (assessed using the modified Barthel Index [BI]) at 12 months. Outcome assessments were masked and were analysed by intention to treat using linear mixed models. Incremental costs and quality-adjusted life-years (QALYs) were calculated using seemingly unrelated regression and bootstrapping. The trial is registered on the ISRCTN registry (ISRCTN54268283).

FINDINGS

We recruited 388 participants between Jan 8, 2021 and July 2, 2022 (mean age 81 years, SD 6·5; 249 (64%) of 388 were women and 139 (36%) were men). 195 participants were randomly assigned to HomeHealth and 193 to treatment as usual. Median follow-up was 363 days (IQR 356-370) in the HomeHealth group and 362 days (IQR 355-373) in the treatment-as-usual group. HomeHealth did not improve BI scores at 12 months (mean difference 0·250, 95% CI -0·932 to 1·432). HomeHealth was superior to treatment as usual with a negative point estimate for incremental costs (-£796; 95% CI -2016 to 424) and positive point estimate for incremental QALYs (0·009, -0·021 to 0·039). There were 55 serious adverse events in the HomeHealth group and 85 in the treatment-as-usual group; none were intervention related.

INTERPRETATION

HomeHealth is a safe intervention with a high probability of cost-effectiveness, driven by a reduction in unplanned hospital admissions. HomeHealth should be considered as a health promotion intervention for older people with mild frailty.

Assessing the feasibility of measuring residents' quality of life in English care homes and the construct validity and internal consistency of measures completed by staff proxy: a cross-sectional study

OBJECTIVES

To assess the feasibility of capturing older care home residents' quality of life (QoL) in digital social care records and the construct validity (hypothesis testing) and internal consistency (Cronbach's alpha) of four QoL measures.

DESIGN

Cross-sectional data collected in wave 1 of the DACHA (Developing resources And minimum dataset for Care Homes' Adoption) study, a mixed-methods pilot of a prototype minimum dataset (MDS).

SETTING

Care homes (with or without nursing) registered to provide care for older adults (>65 years) and/or those living with dementia. All homes used a digital record system from one of two suppliers.

PARTICIPANTS

Data were extracted from 748 residents. All permanent residents, aged 65 years or older, were eligible to participate, including those lacking capacity to consent. Temporary residents and residents in their last weeks of life were excluded.

OUTCOME MEASURES AND ANALYSIS

The English language versions of Adult Social Care Outcomes Toolkit (ASCOT)-Proxy-Resident, ICEpop CAPability measure for Older people (ICECAP-O), EQ-5D-5L proxy and the QUALIDEM were added to the digital record. As there have not been any previous studies of the structural validity of the English language version of the QUALIDEM, ordinal exploratory factor analysis (EFA) was applied for this measure only. Feasibility (% missing by software provider and measure), % floor/ceiling effects (>15% at lower/upper end of the scales), convergent or divergent construct validity (criterion of >75% of hypotheses accepted) and internal consistency (Cronbach's alpha ≥0.7) were assessed for all four measures.

RESULTS

The ordinal EFA of QUALIDEM did not replicate the findings of previous research. A six-factor (36 item) solution was proposed and used in all subsequent analyses. There were low rates of missing data (<5%) for all items, except ASCOT-Proxy-Resident Control (5.1%) and Dignity (6.2%) and QUALIDEM item 35 (5.1%). Ceiling effects were observed for the ASCOT-Proxy-Resident and two of the QUALIDEM subscales. None of the scales had floor effects. Cronbach's alpha indicated adequate internal consistency (α ≥0.70) for the ASCOT-Proxy-Resident, ICECAP-O and EQ-5D-5L proxy. There were issues with two QUALIDEM subscales. Construct validity for all measures was adequate.

CONCLUSIONS

The findings support the use of EQ-5D-5L, ASCOT-Proxy-Resident and the ICECAP-O in care homes for older people. The choice of measure will depend on the construct(s) of interest. More research is needed to establish the psychometric properties of the QUALIDEM in an English care home setting.

Impact of the Smarter Safer Homes Solution on Quality of Life and Health Outcomes in Older People Living in Their Own Homes: Randomized Controlled Trial

BACKGROUND

An increasingly aging population, accompanied by a shortage of residential aged care homes and workforce and consumer feedback, has driven a growing interest in enabling older people to age in place through home-based care. In this context, smart home technologies for remote health monitoring have gained popularity for supporting older people to live in their own homes.

OBJECTIVE

This study aims to investigate the impact of smart home monitoring on multiple outcomes, including quality of life, activities of daily living, and depressive symptoms among older people living in their own homes over a 12-month period.

METHODS

We conducted an open-label, parallel-group randomized controlled trial. The control group continued to receive their existing care from aged care service providers. Meanwhile, the intervention group, in addition to receiving their usual aged care services, had their activities of daily living monitored using a smart home platform. Surveys including the Adult Social Care Outcomes Toolkit (ASCOT), EuroQol-5 Dimensions-5 Levels (EQ-5D-5L), Katz Index of Independence in Activities of Daily Living (Katz ADL), Lawton Instrumental Activities of Daily Living Scale (IADL), and Geriatric Depression Scale (GDS) were conducted at baseline and 6 and 12 months from baseline. Linear mixed-effects models were used to compare the difference between the intervention and control groups, with the ASCOT as the primary outcome measure.

RESULTS

Data from 130 participants were used in the analysis, with no significant differences in baseline characteristics between the control group (n=61) and the intervention group (n=69). In comparison to the control group, the intervention group had a higher ASCOT score at the 6-month assessment (mean difference 0.045, 95% CI 0.001 to 0.089; Cohen d=0.377). However, this difference did not persist at the 12-month assessment (mean difference 0.031, 95% CI -0.014 to 0.076; Cohen d=0.259). There were no significant differences in EQ-5D-5L, Katz ADL, IADL, and GDS observed between the intervention and control groups at the 6-month and 12-month assessments.

CONCLUSIONS

The study demonstrates that smart home monitoring can improve social care-related quality of life for older people living in their own homes. However, the improvement was not sustained over the long term. The lack of statistically significant findings and diminished long-term improvements may be attributed to the influence of the COVID-19 pandemic during the later stage of the trial. Further research with a larger sample size is needed to evaluate the effect of smart home monitoring on broader quality-of-life measures.

Enhancing quality of life measurement: adapting the ASCOT easy read for older adults accessing social care

PURPOSE

This study aimed to adapt and assess the content validity of the ASCOT Easy Read (ASCOT-ER) for older people accessing social care.

METHODS

A co-production working group of 8 older social care users and their supporters was established to evaluate the comprehensibility and relevance of the ASCOT-ER images, wording and layout. Changes made by the working group were iteratively tested using cognitive interviewing techniques (think aloud) with 25 older social care users not able to self-complete the original ASCOT.

RESULTS

Co-research with people with dementia and their supporters was critical to the development of an effective and accessible tool. Issues identified with comprehension, recall, judgement and response were addressed through iterative adjustments to design, layout and wording. An unexpected finding was that illustrations were disliked or disregarded by the majority of people, and, in particular, those living with dementia. This result contrasts with the typical assumption of easy read approaches, where illustrations are expected to enhance comprehension.

CONCLUSION

The ASCOT-ER measure for older people is suitable for older people using social care services with mild to moderate dementia, mild cognitive impairment and other age-related needs. The revisions applied were designed to improve comprehension, judgement and response for this group and even those who were most cognitively impaired experienced fewer issues by the final round of testing. Nonetheless, some prompting was still required, particularly for those with higher levels of cognitive impairment and it is likely that some respondents will require the questionnaire to be administered in an interview format.

Medication adherence and quality of life among geriatric patients: Insights from a hospital-based cross-sectional study in India

BACKGROUND

Understanding the factors that influence medication adherence and the multidimensional aspects of quality of life in the elderly is of paramount importance in enhancing their overall well-being. Since geriatric patients usually suffer from multiple morbidities due to their declining age, the adherence towards their medications plays a very crucial role in their quality of life.

METHODOLOGY

This cross-sectional study explores the intricate relationship between medication adherence and quality of life among 310 elderly patients at a single medical college and hospital. Participants completed the Morisky Medication Adherence Scale (MMAS-8) to assess medication adherence and the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire, which comprises four domains (physical health, psychological health, social relationships, and environment) to evaluate quality of life. Statistical analyses, including correlations, paired t-tests, ANOVA, and Backward Multiple Linear Regression, were employed to examine the relationships and differences among variables.

RESULTS

The findings indicate varying levels of medication adherence among participants, with a significant proportion exhibiting medium adherence (47.1%) and highlighting the need for interventions to address challenges in medication adherence among the elderly population. Notably, gender emerged as a significant factor influencing quality of life, with males reporting higher satisfaction across all domains compared to females. Medication adherence exhibited a significant correlation with the social relationships domain (DOM3) of the WHOQOL-BREF, underlining the importance of adherence in fostering positive social interactions.

CONCLUSION

Our study revealed a significant association between medication adherence (MMAS- 8) and the quality of life (WHOQOL-BREF) among elderly patients. We also observed noteworthy gender differences in quality-of-life perceptions. It emphasizes the need for tailored interventions that consider medication adherence issues to enhance the overall quality of life among this vulnerable population.

Appropriateness of the EQ-HWB for Use in Residential Aged Care: A Proxy Perspective

BACKGROUND AND OBJECTIVE

The EQ Health and Wellbeing (EQ-HWB) is a new generic quality-of-life measure for use in evaluating interventions in health, public health and social care. This study aimed to explore proxies' views regarding the appropriateness of the EQ-HWB for measuring residents' quality of life living in residential aged care facilities.

METHODS

Qualitative think-aloud and semi-structured interviews were conducted with family members and aged care staff across three facilities in Melbourne, Australia. Proxies completed the 25-item EQ-HWB proxy version 2 (i.e. proxy-person perspective) whilst talking through the reasons for choosing their response. All interviews were audio-recorded and transcribed verbatim. A thematic analysis was used for data analysis.

RESULTS

The sample included 29 proxies; nine family members and 20 aged care staff. The first theme summarised proxies' ability to proxy report residents' health and well-being using the EQ-HWB, which highlighted challenges with adherence to the proxy perspective, proxies' limited knowledge about residents, disagreement with residents' self-evaluation and use of heuristics. The second theme reflected feedback on the suitability of the EQ-HWB for use in residential aged care. Although proxies perceived that the EQ-HWB covered important domains, there were concerns about ambiguity, inappropriate examples, double-barrelled items and perceived repetition. Suggestions were made to improve the response options, comprehensiveness, recall period, layout and instructions of the questionnaire.

CONCLUSIONS

While the EQ-HWB captures domains relevant to residential aged care, modifications to item wording and examples are necessary to improve its appropriateness. Use of the proxy-person perspective revealed some challenges that require further consideration.

Psychometric Properties of the World Health Organization Quality of Life Scale for Older Adults (WHO-QoL-Old) in a Mexican Population

BACKGROUND/OBJECTIVE

The present study aimed to contribute to analyzing the psychometric properties of the WHO Quality of Life Scale for Older Adults (WHO-QoL-Old) in a sample of older adults in Michoacán, Mexico.

METHODS

111 older adults from Michoacán, Mexico, participated in the study. Confirmatory factor analysis (CFA) was conducted to test the fit of various models. Data analysis was performed using R Studio, considering the ordinal nature of the items in the model estimation method. Internal consistency was evaluated using the alpha coefficient (α) and McDonald's omega coefficient (ω).

RESULTS

The CFA indicated that the six-correlated-factor model proposed theoretically showed a very good fit (χ2: 397.11, p < 0.001; CFI: 0.958; SRMR: 0.079; RMSEA: 0.079). The factors within the model demonstrated acceptable internal consistency, with an alpha coefficient ranging from 0.739 to 0.874 and an omega coefficient ranging from 0.748 to 0.882.

CONCLUSIONS

It is concluded that the WHO-QoL-Old scale presents good psychometric properties for the Mexican older adult population.

Utility index and vision-related quality of life in patients awaiting specialist eye care

OBJECTIVES

This study aimed to ascertain utility and vision-related quality of life in patients awaiting access to specialist eye care. A secondary aim was to evaluate the association of utility indices with demographic profile and waiting time.

METHODS

Consecutive patients that had been waiting for ophthalmology care answered the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25). The questionnaire was administered when patients arrived at the clinics for their first visit. We derived a utility index (VFQ-UI) from the patients' responses, then calculated the correlation between this index and waiting time and compared utility across demographic subgroups stratified by age, sex, and care setting.

RESULTS

536 individuals participated in the study (mean age 52.9±16.6 years; 370 women, 69% women). The median utility index was 0.85 (interquartile range [IQR] 0.70-0.92; minimum 0.40, maximum 0.97). The mean VFQ-25 score was 70.88±14.59. Utility correlated weakly and nonsignificantly with waiting time (-0.05, P = 0.24). It did not vary across age groups (P = 0.85) or care settings (P = 0.77). Utility was significantly lower for women (0.84, IQR 0.70-0.92) than men (0.87, IQR 0.73-0.93, P = 0.03), but the magnitude of this difference was small (Cohen's d = 0.13).

CONCLUSION

Patients awaiting access to ophthalmology care had a utility index of 0.85 on a scale of 0 to 1. This measurement was not previously reported in the literature. Utility measures can provide insight into patients' perspectives and support economic health analyses and inform health policies.

Using EQ-5D for Proxy Assessment of Health-Related Quality of Life in Residential Care Facilities: A Systematic Review of Feasibility and Psychometric Properties

OBJECTIVES

The accurate assessment of Health-Related Quality of Life (HRQoL) in residents of residential care facilities (RCF) necessitates the use of proxy-reported instruments that possess robust psychometric properties. Generally, these instruments are modified versions of self-reported tools, with adjustments made to pronouns and instructions to better suit the respondent. Among such tools, the EQ-5D has emerged as a prominent instrument for evaluating HRQoL within RCF settings. This review aimed to synthesize evidence on psychometric properties of the proxy version of EQ-5D.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Residents in RCF.

METHODS

An extensive search was conducted across 8 databases, covering articles from inception to May 29, 2023. We included a total of 20 articles reporting data that can be used to evaluate psychometric properties of this instrument in RCF. The quality appraisal employed the COSMIN Risk of Bias checklist, and data synthesis followed COSMIN methodology.

RESULTS

Most of the included studies were conducted in Europe, with 75% using nursing staff as proxies. Missing data rates were 5% for EQ-5D and 26% for EQ VAS. Evidence of moderate certainty on construct validity of the EQ-5D index was inconsistent, although the EQ VAS showed sufficient construct validity supported by high certainty. EQ-5D index responsiveness evidence was limited, characterized by low certainty and inconsistency. Proxy-resident agreement ranged from poor to moderate, and improved with repeated administration for the "mobility" and "usual activities" dimensions. The lowest agreement was observed when staff served as proxies or the proxy-proxy perspective was adopted.

CONCLUSIONS AND IMPLICATIONS

This review offers an overview of the psychometric properties of EQ-5D as a proxy HRQoL measure in RCF. The suboptimal evidence on psychometric properties of EQ-5D indicated the need for more validation studies and cautious use of the instrument in RCF.

The impact of elder abuse training on subacute health providers and older adults: study protocol for a randomized control trial

BACKGROUND

Elder abuse often goes unreported and undetected. Older people may be ashamed, fearful, or otherwise reticent to disclose abuse, and many health providers are not confident in asking about it. In the No More Shame study, we will evaluate a co-designed, multi-component intervention that aims to improve health providers' recognition, response, and referral of elder abuse.

METHODS

This is a single-blinded, pragmatic, cluster randomised controlled trial. Ten subacute hospital sites (i.e. clusters) across Australia will be allocated 1:1, stratified by state to a multi-component intervention comprising a training programme for health providers, implementation of a screening tool and use of site champions, or no additional training or support. Outcomes will be collected at baseline, 4 and 9 months. Our co-primary outcomes are change in health providers' knowledge of responding to elder abuse and older people's sense of safety and quality of life. We will include all inpatients at participating sites, aged 65 + (or aged 50 + if Aboriginal or Torres Strait Islander), who are able to provide informed consent and all unit staff who provide direct care to older people; a sample size of at least 92 health providers and 612 older people will provide sufficient power for primary analyses.

DISCUSSION

This will be one of the first trials in the world to evaluate a multi-component elder abuse intervention. If successful, it will provide the most robust evidence base to date for health providers to draw on to create a safe environment for reporting, response, and referral.

Validation of Quality-of-Life assessment tool for Ethiopian old age people

Background

A valid and reliable quality of life (QOL) assessment tool is critical for identifying health issues, evaluating health interventions, and establishing the best health policies and care plans. One of the tools for this goal is the World Health Organization's Quality of Life Old module (WHOQOL-OLD). It is validated and available in more than 20 languages globally, except Amharic (the widely spoken language in Ethiopia). As a result, the purpose of this study was to translate it into Amharic language and validate it among the elderly people in Bahir Dar City, Northwestern Ethiopia.

Methods

This was a cross-sectional study conducted among 180 community-dwelling old age people in Bahir Dar City, Ethiopia, from January 16 to March 13, 2021. Psychometric validation was achieved through Cronbach's alpha of the internal consistency reliability test and construct validity from confirmatory factor analysis.

Results

The study participants were aged between 60 and 90 years, with a mean age of 69.44. Females made up 61.7% of the study population, and 40% of them could not read or write. The results showed a relatively low level of quality of life, with a total transformed score of 58.58±23.15. The Amharic version of the WHOQOL-OLD showed a Cronbach's Alpha value of 0.96 and corrected item-total correlations of more than 0.74. The confirmatory factor analysis confirmed the six-domain model with a chi-square (X2) of 341.98 and a p-value less than 0.001. The comparative fit index (CFI) was 0.98, Tucker-Lewis's index (TCL) was 0.97, and the root mean square error of approximation (RMSEA) was 0.046.

Conclusion

The Amharic version of the WHOQOL-OLD indicated good internal consistency reliability and construct validity. The tool can be utilized to provide care to Ethiopian community-dwelling old age people.

Psychometric properties of the World Health Organization WHOQOL-AGE Scale in Singapore

WHOQOL-AGE is a promising quality of life (QOL) tool that has not been fully validated in Asia. The present study aimed to verify its factor structure and psychometric properties among community-dwelling older adults in Singapore. This study was cross-sectional and used data (N = 593) from the Community Health and Intergenerational study that interviewed older adults between 2018 and 2021. Confirmatory factor analysis (CFA) was used to examine the factor structure of the WHOQOL-AGE, and Cronbach's alpha coefficients were employed to examine internal consistency. Spearman's rho correlations coefficients between WHOQOL-AGE and other related scales (Satisfaction with Life and the Friendship) examined convergent validity. A Pearson's correlation coefficient between WHOQOL-AGE and compassion scale examined discriminant validity. An independent t test was used to demonstrate known-groups validity, examining differences in QOL scores between individuals with and without chronic medical conditions. Findings supported a bifactor model with more satisfactory goodness-of-fit indices than the original two-factor model and the two-correlated factor model. WHOQOL-AGE showed adequate internal consistency (Cronbach's alpha coefficients > .70). Good convergent validity was demonstrated by moderate-to-large correlations between WHOQOL-AGE and satisfaction with life (rs = .54) as well as social connectedness (rs = .33). Discriminant validity was shown by low correlations between WHOQOL-AGE and compassion (r = .19). Findings also indicated good known-groups validity (p < 0.01). The WHOQOL-AGE showed promising psychometric properties using an Asian convenience sample and can be useful in large-scale studies or busy clinical settings.

Feasibility of self-reported health related quality of life assessment with older people in residential care: insights from the application of eye tracking technology

PURPOSE

Increasingly there are calls to routinely assess the health-related quality of life (HRQoL) of older people receiving aged care services, however the high prevalence of dementia and cognitive impairment remains a challenge to implementation. Eye-tracking technology facilitates detailed assessment of engagement and comprehension of visual stimuli, and may be useful in flagging individuals and populations who cannot reliably self-complete HRQoL instruments. The aim of this study was to apply eye-tracking technology to provide insights into self-reporting of HRQoL among older people in residential care with and without cognitive impairment.

METHODS

Residents (n = 41), recruited based on one of three cognition subgroups (no, mild, or moderate cognitive impairment), completed the EQ-5D-5L on a computer with eye tracking technology embedded. Number and length of fixations (i.e., eye gaze in seconds) for key components of the EQ-5D-5L descriptive system were calculated.

RESULTS

For all dimensions, participants with no cognitive impairment fixated for longer on the Area of Interest (AOI) for the response option they finally chose, relative to those with mild or moderate cognitive impairment. Participants with cognitive impairment followed similar fixation patterns to those without. There was some evidence that participants with cognitive impairment took longer to complete and spent relatively less time attending to the relevant AOIs, but these differences did not reach statistical significance generally.

CONCLUSIONS

This exploratory study applying eye tracking technology provides novel insights and evidence of the feasibility of self-reported HRQoL assessments in older people in aged care settings where cognitive impairment and dementia are highly prevalent.

Child-Parent Agreement in the Assessment of Health-Related Quality of Life Using the CHU9D and the PedsQLTM

OBJECTIVE

This study examined the inter-rater agreement between child-self and parental proxy health-related quality of life (HRQoL) ratings (overall and domain level) using two different generic child-specific measures, the Child Health Utility 9D (CHU9D) and the Pediatric Quality of Life Inventory (PedsQLTM), in a community-based sample of Australian children. A secondary objective was to investigate the impact of age on child-parent agreement across the dimensions of the two measures.

METHODS

A total of 85 child-parent dyads (children aged 6-12 years) recruited from the community completed the self and proxy versions of the CHU9D and the PedsQLTM, respectively. The inter-rater agreement was estimated using Concordance Correlation Coefficients (CCC) and Gwet's Agreement Coefficient (AC1) for the overall sample and across age-groups.

RESULTS

Agreement was low for overall HRQoL for both the CHU9D (CCC = 0.28) and the PedsQLTM (CCC = 0.39). Across the CHU9D dimensions, agreement was the highest for 'sad' (AC1 = 0.83) and lowest for 'tired' (AC1 = 0.31). The PedsQLTM demonstrated stronger agreement (AC1 = 0.41-0.6) for the physical health dimension but weaker for the psychosocial dimensions (AC1 < 0.4). Except for the 'tired' dimension, agreement was consistent across age-groups with the CHU9D, whilst the PedsQLTM showed poor agreement for most of the psychosocial health items among the older age-groups only (8-10 and 11-12 years).

CONCLUSION

This study highlights that the agreement between child and parent proxy reported HRQoL may be influenced by both the measure used and the age of the child. These findings may have implications for the economic evaluation of healthcare interventions and services in child populations when both child and proxy perspectives are considered in the assessment of child HRQoL.

Face Validity of Four Preference-Weighted Quality-of-Life Measures in Residential Aged Care: A Think-Aloud Study

OBJECTIVE

There is an increased use of preference-weighted quality-of-life measures in residential aged care to guide resource allocation decisions or for quality-of-care assessments. However, little is known about their face validity (i.e., how understandable, appropriate and relevant the measures are 'on their face' when respondents complete them). The aim of this study was to assess the face validity of four preference-weighted measures (i.e., EQ-5D-5L, EQ-HWB, ASCOT, QOL-ACC) in older people living in residential aged care.

METHODS

Qualitative cognitive think-aloud interviews were conducted using both concurrent and retrospective think-aloud techniques. To reduce burden, each resident completed two measures, with the four measures randomised across participants. Audio recordings were transcribed and framework analysis was used for data analysis, based on an existing framework derived from the Tourangeau four-stage response model.

RESULTS

In total, 24 interviews were conducted with residents living across three residential aged care facilities in Melbourne, Australia. Response issues were identified across all four measures, often related to comprehension and difficulty selecting a response level due to double-barrelled and ambiguous items that have different meanings in the residential aged care context. We also identified issues related to understanding instructions, non-adherence to the recall period, and noted positive responding that requires attention when interpreting the data.

CONCLUSIONS

Our findings provide further evidence on the appropriateness of existing measures, indicating numerous response issues that require further research to guide the selection process for research and practice.

Measurement properties of utility-based health-related quality-of-life measures in cardiac rehabilitation: a systematic review protocol

OBJECTIVE

This review will identify and appraise existing evidence on the measurement properties of utility-based health-related quality-of-life (HRQoL) measures used in cardiac rehabilitation programs. The review will map the measure domains against the International Classification of Functioning, Disability and Health and the International Consortium of Health Outcome Measures domains for cardiovascular disease.

INTRODUCTION

Improving HRQoL is an international key indicator for delivering high-quality and person-centered secondary prevention programs. Many instruments and measures assess HRQoL in individuals undergoing cardiac rehabilitation. Utility-based measures are suitable for calculating quality-adjusted life years, a required outcome metric in cost-utility analysis. Cost-utility analysis requires the use of utility-based HRQoL measures. However, there is no consensus on which utility-based measure is best for populations undergoing cardiac rehabilitation.

INCLUSION CRITERIA

Eligible studies will include patients aged ≥18 years with cardiovascular disease who are undergoing cardiac rehabilitation. Empirical studies that assess quality of life or HRQoL using a utility-based, health-related, patient-reported outcome measure or a measure accompanied by health state utilities will be eligible. Studies must report at least 1 of the following measurement properties: reliability, validity, responsiveness.

METHODS

This review will follow the JBI methodology for systematic reviews of measurement properties. The following databases will be searched from inception to the present: MEDLINE, Emcare, Embase, Scopus, CINAHL, Web of Science Core Collection, Informit, PsyclNFO, REHABDATA, and the Cochrane Library. Studies will be critically appraised using the The COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) risk of bias checklist. The review will be reported in line with the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines.

Validity and reliability of the WHOQOL-BREF in the measurement of the quality of life of Sickle disease patients in Bahrain

Background

Limited attention is devoted to the improvement of the quality of life of patients suffering from the negative consequences of Sickle cell disease (SCD). Our study focuses on the evaluation of the performance of the WHOQOL-BREF as a tool to measure the quality of life of SCD Patients in Bahrain.

Methods

We conducted a cross-sectional study that enrolled 273 SCD patients selected using a simple random sampling technique from primary health-care centers in Bahrain in 2019. A designed questionnaire including the WHOQOL-BREF was filled by the patients in the health centers. The reliability of the WHOQOL-BREF was assessed by standardized Cronbach's alpha coefficient, and the validity was measured by convergent validity, principal component analysis and confirmatory factor analysis.

Results

The WHOQOL-BREF had good internal consistency as Cronbach's alpha coefficient for the overall scale was 0.91. The convergent validity results indicated that the correlation coefficients values for all scale domains are significantly correlated at α < 0.01. Confirmatory factor analysis found that the four-domain structure produced a robust fit to the data.

Conclusion

The WHOQOL-BREF tool has high internal consistency and validity in assessing the quality of life of Sickle Disease patients in Bahrain.

Exploring differences and similarities of EQ-5D-3L, EQ-5D-5L and WHOQOL-OLD in recipients of aged care services in Germany

European countries more than ever face shifts towards aging societies with accompanying challenges for health and aged care services. Economic evaluation has mainly relied on health measures such as EQ-5D across populations and conditions. We want to know how well the EQ-5D performs in the target population to avoid bias to the disadvantage of older adults and care-dependents. Therefore, we aim to explore differences and similarities of EQ-5D-3L and EQ-5D-5L in comparison to the old-age specific WHOQOL-OLD instrument in a sample of older adults receiving aged care services. We collected data from n = 329 older adults (≥65 years) receiving aged care services in Germany; the majority was at least 80 years and had varying care needs. We assessed instruments' feasibility, test-retest reliability, instruments' association and sensitivity to known-group differences. In terms of feasibility and test-retest reliability both EQ-5D versions performed better than the WHOQOL-OLD. All measures differentiated well between groups based on aspects of general health and care levels. The analysis of relationship between measures indicated that EQ-5D and WHOQOL-OLD assess partially overlapping, but distinct constructs. We found no clear evidence of superiority of either EQ-5D version over the other. The EQ-5D-5L performed better in terms of test-retest reliability and stronger correlations with WHOQOL-OLD facets. We conclude that using the WHOQOL-OLD alongside EQ-5D in this sample added further information on different aspects of quality of life.

Feasibility, validity and reliability of the ASCOT-Proxy and ASCOT-Carer among unpaid carers of people living with dementia in England

BACKGROUND

People with dementia living at home represent a growing group of social care services users in England. Many are unable to complete questionnaires due to cognitive impairment. The ASCOT-Proxy is an adapted version of an established measure, ASCOT, which was developed as a way of collecting social care-related quality of life (SCRQoL) data from this group of service users, either alone or alongside the ASCOT-Carer, a measure of SCRQoL for unpaid carers. The ASCOT-Proxy includes two perspectives, the proxy-proxy perspective ('My opinion: What I think') and proxy-person perspective ('What I think the person I represent thinks'). We aimed to establish the feasibility, construct validity and reliability of the ASCOT-Proxy and ASCOT-Carer, with unpaid carers of people with dementia living at home unable to self-report. We also aimed to establish structural characteristics of the ASCOT-Proxy.

METHODS

Cross-sectional data were collected using self-administered questionnaire (paper or online) among unpaid carers living in England between January 2020 and April 2021. Unpaid carers could take part if they supported someone living with dementia who was unable to self-complete a structured questionnaire. The person living with dementia or their unpaid carer had to use at least one social care service. We used the proportion of missing data to establish feasibility, ordinal exploratory factor analysis to establish structural characteristics, Zumbo's ordinal alpha for internal reliability, and hypothesis testing for construct validity. We also conducted Rasch analysis.

RESULTS

We analysed data for 313 carers (62.4(± 12.0) years, 75.7% (N=237) females). We were able to calculate the ASCOT-Proxy-proxy overall score for 90.7% of our sample, the ASCOT-Proxy-person overall score for 88.8% of our sample and in case of the ASCOT-Carer for 99.7% of our sample. As there was an issue with structural characteristics of the ASCOT-Proxy-proxy we conducted Rasch, reliability and construct validity analysis for the ASCOT-Proxy-person and ASCOT-Carer only.

CONCLUSIONS

This was a first study to explore psychometric characteristics of the ASCOT-Proxy and ASCOT-Carer with unpaid carers of people with dementia living at home unable to self-report. There are some aspects of the psychometric characteristics of the ASCOT-Proxy and ASCOT-Carer that warrant further investigation in future. Trial registration NA.

A head-to-head comparison of well-being of older people (WOOP) and EQ-5D-5L in patients, carers and general public in China

Recently, well-being of older people measure (WOOP) was developed and validated in a Dutch population. Although WOOP was developed targeting the older people, it has the potential for use in a wider population. In this study, we aimed to examine the relationship between WOOP and EQ-5D-5L and compared their psychometric properties in a sample of patients, carers and healthy general public covering a wider age group. We conducted a cross-sectional study in Guizhou Province, China between July and August 2022. Data was collected using paper and pencil. We analysed and reported the acceptability, item response distribution, the Spearman correlation coefficients of all items, the Exploratory Factor Analysis (EFA) of all items, the known-group validity and the convergent validity of EQ-5D-5L utility and WOOP utility. A total of 322 participants completed the survey with 105 patients, 101 carers and 116 healthy general public. 9% of participants had at least one missing response. Three items of WOOP did not have any level 5 responses and EQ-5D-5L had more level 1 responses. The correlations were low between EQ-5D-5L and WOOP items and the three-factor EFA showed these two instruments had only one shared factor and the other two factors were only related to WOOP items. Younger people had lower missing response rate and a different response distribution for three items. WOOP measures a broader construct beyond health while EQ-5D-5L is a more sensitive instrument when health is considered alone. There is a potential of using WOOP in a wider population.

Derivation, and establishment of the validity and reliability, of the CASP-11-SG quality of life scale among community-dwelling older adults

PURPOSE

The number and proportion of older adults, aged ≥ 60 years, in Singapore is rapidly increasing. A valid and reliable quality of life (QoL) measure will enable assessment of their situation and help evaluate social and clinical interventions, potentially improving care. This study aims to evaluate the validity and reliability of the control, autonomy, self-realization, and pleasure (CASP)-12v.3 QoL scale and establish a scale suitable for use among older adults in Singapore.

METHODS

Data from 3526 community-dwelling older adults from a national survey was used. Measurement properties of the CASP-12v.3 scale were evaluated. Confirmatory factor analysis (CFA; testing single- and two-factor models with residual covariances for negatively worded items and a bifactor model) was performed in half of the sample and exploratory factor analysis (EFA) was performed in the other half. The results led to revised CFA models and the CASP-11-SG scale. The CASP-11-SG scale's measurement properties, convergent, and known-groups validity, and measurement equivalence/invariance (ME/I) across English and Chinese languages were evaluated.

RESULTS

Item 3 'I feel free to plan for the future' of the CASP-12v.3 scale had low correlation with other items of the control/autonomy subscale, low item-total correlation and high item-scale correlation. While CFA and EFA supported the two-factor model, removing item 3 improved model fit. The resulting CASP-11-SG scale (Cronbach's alpha: 0.81) demonstrated convergent and known-groups validity and partial ME/I across English and Chinese languages.

CONCLUSION

The CASP-11-SG scale, with satisfactory psychometric properties, can be used for assessing QoL among older adults in Singapore.

Measurement properties of the EQ-5D in populations with a mean age of ≥ 75 years: a systematic review

PURPOSE

Healthcare interventions for middle-old and oldest-old individuals are often (economically) evaluated using the EQ-5D to measure health-related quality of life (HrQoL). This requires sufficient measurement properties of the EQ-5D. Therefore, the current study aimed to systematically review studies assessing the measurement properties of the EQ-5D in this population.

METHODS

The databases PubMed, Cochrane library, Web of Science, Embase, and EconLit were searched for studies providing empirical evidence of reliability, validity, and/or responsiveness of the EQ-5D-3L and EQ-5D-5L in samples with a mean age ≥ 75 years. Studies were selected by two independent reviewers, and the methodological quality was assessed using the COSMIN Risk of Bias checklist. Results were rated against updated criteria for good measurement properties (sufficient, insufficient, inconsistent, indeterminate). The evidence was summarized, and the quality of evidence was graded using a modified GRADE approach.

RESULTS

For both EQ-5D versions, high-quality evidence for sufficient convergent validity was found. Known-groups validity was sufficient for the EQ-5D-5L (high-quality evidence), whereas the results were inconsistent for the EQ-5D-3L. Results regarding the reliability were inconsistent (EQ-5D-3L) or entirely lacking (EQ-5D-5L). Responsiveness based on correlations of change scores with instruments measuring related/similar constructs was insufficient for the EQ-5D-3L (high-quality evidence). For the EQ-5D-5L, the available evidence on responsiveness to change in (Hr)QoL instruments was limited.

CONCLUSION

Since the responsiveness of the EQ-5D in a population of middle-old and oldest-old individuals was questionable, either using additional instruments or considering the use of an alternative, more comprehensive instrument of (Hr)QoL might be advisable, especially for economic evaluations.

Validating the Well-Being of Older People (WOOP) Instrument in China

Generic health-related quality of life (HRQoL) measures have been used for estimating utility value, which is then used for calculating quality-adjusted life years (QALYs). HRQoL measures may not capture many of the relevant and important non-health aspects of quality of life. The well-being of older people (WOOP) instrument was first developed in the Netherlands. This study aimed to validate this new instrument among older people in China. WOOP was first translated into simplified Chinese (for use in Mainland China) by two experienced translators. From July to August 2022, a cross-sectional study was conducted on a convenience sample of 500 older people in Southwestern China. Older people who provided consent reported their demographic information and completed the simplified Chinese version of the WOOP instrument using a pencil and paper. The feasibility of WOOP was determined by the percentage of missing responses. Then, using the data without any missing responses, we examined the item response distributions, pairwise Spearman correlations, underlying factors, and known-group validity of WOOP. Among the nine items of WOOP, three had more than 10% missing responses. The response distributions of the nine items were overall good without signs of ceiling and floor effects. The correlations among the WOOP items were low. A two-factor exploratory factor analysis model suggested that the WOOP items can be categorized into either internal or external well-being items. Good known-group validity results were found. Some WOOP items may not be easily understood by a small proportion of rural residents. However, other results have suggested WOOP to be a valid instrument for measuring the well-being of the elderly in China. The availability of WOOP enables the measurement of well-being-related utility.

Assessing feasibility, construct validity, and reliability of a new aged care-specific preference-based quality of life instrument: evidence from older Australians in residential aged care

BACKGROUND

Quality of Life-Aged Care Consumers (QOL-ACC) is a new older-person-specific quality of life instrument designed for application in quality assessment and economic evaluation in aged care. The QOL-ACC was designed from its inception with older people receiving aged care services ensuring its strong content validity. Given that the QOL-ACC has already been validated in home care settings and a preference-weighted value set developed, we aimed to assess feasibility, construct validity and reliability of the QOL-ACC in residential aged care settings.  METHODS: Individuals living in residential aged care facilities participated in an interviewer-facilitated survey. The survey included the QOL-ACC, QCE-ACC (quality of aged care experience measure) and two other preference-based quality of life instruments (ASCOT and EQ-5D-5L). Feasibility was assessed using missing data and ceiling/floor effects. Construct validity was assessed by exploring the relationship between the QOL-ACC and other instruments (convergent validity) and the QOL-ACC's ability to discriminate varying levels of self-rated health and quality of life. Internal consistency reliability was assessed using Cronbach's alpha (α).

RESULTS

Of the 200 residents (mean age, 85 ± 7.7 years) who completed the survey, 60% were female and 69% were born in Australia. One in three participating residents self-rated their health as fair/poor. The QOL-ACC had no missing data but had small floor effects (0.5%) and acceptable ceiling effects (7.5%). It demonstrated moderate correlation with ASCOT (r = 0.51, p < 0.001) and EQ-5D-5L (r = 0.52, p < 0.001) and a stronger correlation with the QCE-ACC (r = 0.57, p < 0.001). Residents with poor self-rated health and quality of life had significantly lower scores on the QOL-ACC. The internal consistency reliability of the QOL-ACC and its dimensions was good (α = 0.70-0.77).

CONCLUSIONS

The QOL-ACC demonstrated good feasibility, construct validity and internal consistency reliability to assess aged care-related quality of life. Moderate correlations of the QOL-ACC and other instruments provide evidence of its construct validity and signifies that the QOL-ACC adds non-redundant and non-interchangeable information beyond the existing instruments. A stronger correlation with the QCE-ACC than other instruments may indicate that quality of life is more intimately connected with the care experience than either health- or social-related quality of life in residential aged care settings.

A Qualitative Investigation of Older Adults' Conceptualization of Quality of Life and a Think-Aloud Content Validation of the EQ-5D-5L, SF-12v2, Warwick Edinburgh Mental Wellbeing Scale, and Office of National Statistics-4

OBJECTIVES

Old age is characterized by declining health, comorbidities, and increasing health and social care service use. Traditionally, patient-reported outcome measures (PROMs) including the EQ-5D-5L and SF-12v2 have focused on health. Nevertheless, aged care often aims to improve broader elements of quality of life (QoL), captured by well-being measures, such as the Warwick Edinburgh Mental Wellbeing Scale (WEMWBS) and Office of National Statistics-4 (ONS-4). This study investigates older adults' conceptualization of QoL and the content validity of the EQ-5D-5L, SF-12v2, WEMWBS, and ONS-4 in measuring their QoL.

METHODS

Qualitative cognitive think-aloud interviews were undertaken with older adults aged 75+, exploring their views on what was important to QoL and, for each measure, the relevance, acceptability, and interpretation of items; suitability of response options; and the comprehensiveness of the measure. Conceptualization of QoL was analyzed thematically and content validity using framework analysis.

RESULTS

Twenty interviews were undertaken. Older adults' conceptualization of QoL centered on health, ability to perform usual activities, social contact, and emotional functioning. Possible response shift was observed, as older adults assessed their health relative to lower health expectations at their age or to people in worse states. Participants questioned the relevance of negatively phrased mental items and often preferred the functioning-focused EQ-5D-5L to more subjective ONS-4 and WEMWBS items. Domains suggested to improve comprehensiveness included social contact, coping, security, dignity, and control.

CONCLUSIONS

These findings are useful to researchers developing new PROMs for older adults or for the developers of included PROMs considering permanently adapting or bolting-on domains to improve content validity in older adults.

Health-related quality of life in various health conditions: two consecutive surveys of older Japanese adults

PURPOSE

Measuring health-related quality of life (HRQOL) in various health conditions in different countries is important given the regional differences. This study employed large-scale nationwide data targeting older adults in Japan to estimate the HRQOL in the key health conditions that are the major causes of disability.

METHODS

Our data were derived from two survey waves (2016 and 2019 surveys) of cross-sectional data from the Japan Gerontological Evaluation Study, an ongoing nationwide study targeting functionally independent older adults in Japan. A total of 28,345 individuals from 27 of the 47 Japanese provinces were analyzed. The EuroQoL 5-dimension 5-level instrument (EQ-5D-5L) was employed to assess the HRQOL utility scores. The targeted minimum loss-based estimator with sampling weighting methods was applied to estimate the utility score in eight major health conditions, including sensory organ disease, musculoskeletal disease, oral disorders, and depressive disorders.

RESULTS

The estimated HRQOL utility score for those with the poorest health conditions in self-rated health, hearing loss, vision loss, number of remaining teeth (e.g., no teeth with no denture use), oral dysfunction, depressive symptoms, chronic low back pain, and chronic knee pain was 0.576 (95% confidence interval (CI) 0.555-0.598), 0.768 (95% CI 0.737-0.800), 0.680 (95% CI 0.662-0.699), 0.809 (95% CI 0.796-0.821), 0.776 (95% CI 0.764-0.788), 0.723 (95% CI 0.710-0.737), 0.715 (95% CI 0.690-0.739), and 0.742 (95% CI 0.722-0.763), respectively.

CONCLUSION

We successfully provided a catalog for the HRQOL utility score in key health conditions that are the leading causes of disability among older adults.

Latent profile analysis for quality of life in older patients

Background

Quality of life (QOL) is a complex concept known for being influenced by socio-demographic characteristics, individual needs, perceptions and expectations. The study investigates influences of such heterogeneous variables and aims to identify and describe subgroups of older patients who share similar response patterns for the four domains (physical health, psychological health, social relationships and environment) of World Health Organization Quality of Life instrument, Short Form (WHOQOL-BREF).

Methods

The sample used included older Romanian patients (N = 60; equal numbers of men and women; mean age was 71.95, SD = 5.98). Latent Profile Analysis (LPA) was conducted to explore quality of life profiles with the four WHOQOL-BREF domains as input variables. Differences between profiles were analysed by MANOVA and ANOVAs as a follow-up.

Results

The LPA results showed that the three-profile model was the most suitable and supported the existence of three distinct QOL profiles: low and very low (28.3%), moderate (63.3%) and high (8.4%). The relative entropy value was high (0.86), results pointed to a good profile solution and the three profiles differed significantly from one another.

Conclusion

Our results reveal heterogeneity within the older adult sample and provide meaningful information to better tailor QOL improvement programs to the needs of older patient groups, especially those designed for patients of profiles related to poorer QOL in different domains.

A systematic review to identify the use of stated preference research in the field of older adult care

In the design of long-term care systems, preferences can serve as an essential indication to better tailor services to the needs, wishes and expectations of its consumers. The aim of this systematic review was to summarize and synthesize available evidence on long-term care preferences that have been elicited by quantitative stated-preference methods. The databases PubMed and Web of Science were searched for the period 2000 to 2020 with an extensive set of search terms. Two independent researchers judged the eligibility of studies. The final number of included studies was 66, conducted in 19 different countries. Studies were systematized according to their content focus as well as the survey method used. Irrespective of the heterogeneity of studies with respect to research focus, study population, sample size and study design, some consistent findings emerged. When presented with a set of long-term care options, the majority of study participants preferred to "age in place" and make use of informal or home-based care. With increasing severity of physical and cognitive impairments, preferences shifted toward the exclusive use of formal care. Next to the severity of care needs, the influence on preferences of a range of other independent variables such as income, family status and education were tested; however, none showed consistent effects across all studies. The inclusion of choice-based elicitation techniques provides an impression of how studies operationalized long-term care and measured preferences. Future research should investigate how preferences might change over time and generations as well as people's willingness and realistic capabilities of providing care.

Valuing the Quality-of-Life Aged Care Consumers (QOL-ACC) Instrument for Quality Assessment and Economic Evaluation

OBJECTIVE

This paper reports on the valuation of the classification system for the Quality-of-Life Aged Care Consumers (QOL-ACC) instrument using a discrete choice experiment (DCE) with duration with a large sample of older people receiving aged care services.

METHODS

A DCE with 160 choice sets of two quality-of-life state-survival duration combinations blocked into 20 survey versions, with eight choice sets in each version, was designed and administered through an on-line survey to older Australians receiving aged care services in home and via interviewer facilitation with older people in residential aged care settings. Model specifications investigating preferences with respect to survival duration and interactions between QOL-ACC dimension levels were estimated. Utility weights were developed, with estimated coefficients transformed to the 0 (being dead) to 1 (full health) scale to generate a value set suitable for application in quality assessment and for the calculation of quality-adjusted life-years for use in economic evaluation.

RESULTS

In total, 953 older people completed the choice experiment with valid responses. The estimation results from econometric model specifications indicated that utility increased with survival duration and decreased according to quality-of-life impairment levels. An Australian value set (range - 0.56 to 1.00) was generated for the calculation of utilities for all QOL-ACC states.

CONCLUSION

The QOL-ACC is unique in its focus on measuring and valuing quality of life from the perspective of older people themselves, thereby ensuring that the preferences of aged care service users are the primary focus for quality assessment and economic evaluation.

Health, well-being and quality of life in aged care: Validation of theoretical domains to inform a person-centred outcomes measurement framework

OBJECTIVES

The constructs of health, well-being and quality of life are not routinely understood or measured for people accessing aged care services. This study aimed to identify and validate theoretical domains of health, well-being and quality of life for recipients of care, their informal carers and staff, and inform the development of a person-centred outcomes measurement framework.

METHODS

First, a rapid review to identify recurrent domains of health, well-being and quality-of-life in aged care, using systematic searches of electronic databases, and review of grey literature, following the PRISMA guidelines. Second, establish content validity of identified domains using (a) Delphi technique with n = 134 aged care staff, care recipients and caregivers, and (b) comparability with categories within the International Classification of Functioning, Disability and Health (ICF) and ICF Geriatric Core Set.

RESULTS

From 972 records detected in the rapid review, 19 peer-reviewed research articles and 27 grey literature sources were included in the content analysis. Twenty-four domains and 109 concepts were identified, and health, quality of life, security and food and nutrition were ranked as the most important. One domain, cognition, linked to both the Geriatric Core Set and ICF, and 37% of domains and 39% of concepts were evident within the ICF.

CONCLUSIONS

This study identified and validated 24 important domains of health, well-being and quality of life for the older person receiving care, their informal carers and staff. These domains can be used to guide the selection of outcome measures and facilitate person-centred care and care planning.

Influence of Depression and Sleep Quality on Postoperative Outcomes after Total Hip Arthroplasty: A Prospective Study

The trend of Total Hip Arthroplasty (THA) is projected to grow. Therefore, it has become imperative to find new measures to improve the outcomes of THA. Several studies have focused attention on the influence of psychological factors and sleep quality on surgical outcomes. The consequences of depressive states may affect outcomes and also interfere with rehabilitation. In addition, sleep quality may be an essential factor in determining surgical outcomes. To our knowledge, few articles focus on the influence of these factors on THA results. The present study investigates a possible correlation between preoperative depression or sleep quality and postoperative outcomes of THA. This study was conducted with 61 consecutive patients undergoing THA from January 2020 to January 2021. Patients were assessed preoperatively using GDS and PSQI, and six months postoperatively using FJS-12, SF-36, WOMAC, PSQI, and GDS. To simplify comparisons, the overall scores were normalized to range from 0 (worst condition) to 100 points (best condition). A total of 37 patients (60.7%) were classified as depressed and 24 as not depressed (39.3 %) in the preoperative assessment. A low–moderate positive correlation between preoperative GDS score and FJS-12 (rho = 0.22, p = 0.011), SF-36-PCS (rho = 0.328, p = 0.01), and SF-36-MCS (rho = 0.293, p = 0.022) scores at six-month follow-up was found. When the normalized preoperative GDS score was high (no depression), the FJS-12, SF-36-PCS, and SF-36-MCS scores tended to increase more compared to the other group. Statistically significant differences between the two groups were found in postoperative FJS-12 (p = 0.001), SF-36-PCS (p = 0.017), and SF-36-MCS scores (p = 0.016). No statistically significant correlation between preoperative PSQI score and postoperative outcome measures was found. Preoperatively depressed patients had a low–moderate positive correlation with postoperative SF-36 and FJS-12 scores. There was no correlation between sleep quality and postoperative outcome measures of THA.

A Validation Study of the EQ-5D-5L and ICEpop Capability Measure for Older People Among Older Individuals With Depressive Symptoms in Brazil

OBJECTIVES

This study aimed to assess the known-groups validity of the EQ-5D-5L and the ICEpop Capability Measure for Older People (ICECAP-O), 2 outcome measures used in economic evaluation, among older adults with depressive symptoms in socioeconomically deprived areas of Brazil. We also explored the role of education and income on responses to these measures.

METHODS

This cross-sectional study used baseline data from PROACTIVE, a cluster randomized controlled trial to evaluate a psychosocial intervention for late-life depression among older adults. Participants aged ≥60 years with a 9-item Patient Health Questionnaire score ≥10 were recruited from 20 primary healthcare clinics. Ordered logistic regression models assessed the association between depressive symptoms severity, income, and education and dimension-level responses on the EQ-5D-5L and ICECAP-O. Multivariable regression models investigated the ability of EQ-5D-5L and ICECAP-O scores to discriminate between depressive symptoms severity levels and other characteristics, including education level and household income.

RESULTS

A total of 715 participants were included in the study. Depressive symptoms severity was associated with all EQ-5D-5L and ICECAP-O dimensions, except the ICECAP-O enjoyment attribute. In contrast, household income was only associated with the ICECAP-O security attribute. Higher severity of depressive symptoms (9-item Patient Health Questionnaire scores) was also strongly associated with lower (ie, worse) scores on both measures in all models. Education level and household income showed no association with either EQ-5D-5L or ICECAP-O scores.

CONCLUSIONS

To best of our knowledge, this is the first study that investigated the validity of these 2 measures among older adults in Brazil. Both EQ-5D-5L and ICECAP-O showed evidence of validity in differentiating depressive symptom severity.

Do we agree or disagree? A systematic review of the application of preference-based instruments in self and proxy reporting of quality of life in older people

PURPOSE

Quality of life is an important person-centred outcome in health and aged care settings. Due to an increasing prevalence of cognitive decline and dementia in ageing populations, a proportion of older people receiving health and aged care services may not be able to reliably assess their own quality of life, highlighting the need for proxy assessment. This systematic review sought to investigate the level of agreement between self and proxy-report of older people's quality of life using established preference-based instruments of quality of life suitable for economic evaluation.

METHODS

A systematic review was conducted following PRISMA guidelines. Eight databases were searched: Web of Science, Scopus, Medline, Econlit, PsychINFO, CINAHL, Ageline and Cochrane Library. Information was extracted on the instruments, population samples (including any cognitive thresholds applied), mean scores, type of proxy, and measures of inter-rater agreement.

RESULTS

A total of 50 studies using eight different preference-based quality of life instruments were identified. Most studies were cross-sectional (72%) with a wide variety of cognitive assessments and thresholds applied to define older participants with cognitive impairment. The most common proxies were family members, mostly spouses. The level of agreement between self and proxy-report was generally poor - irrespective of the instrument applied or type of proxy - with proxy-report generally indicating lower levels of quality of life than self-report. There was some evidence of stronger agreement on more observable quality of life domains e.g., physical health and mobility, relative to less observable domains e.g. emotional well-being. Few studies tracked self and/or proxy-report of quality of life longitudinally.

CONCLUSIONS

More research is needed to develop evidence to inform guidance on self-report versus proxy-report of quality of life for older people receiving health and aged care services. Until then, the collection of both self and proxy reports as complementary measures is indicated.

Factors Associated with Health-Related Quality of Life among Older Adults in Rural South Korea Based on Ecological Model

As the portion of older adults in the population in rural areas of South Korea exceeds 20%, the importance of health-related quality of life is increasing. The aim of the study was to examine the health-related quality of life through the ecological model and its basic determining factors for older adults. The study was conducted on 184 respondents aged 65 and over living in rural areas of South Korea. The measurements were health-related quality of life, health care service needs, sleep quality, social support, and personal characteristics. The collected data were tested using descriptive, t-test, ANOVA, and hierarchical multiple regression. The results showed that older adults in rural areas experienced a low quality of life. Religion, having a helper, and social support were significantly related to health-related quality of life in older adults. This directly shows that the government should make efforts to build a social support system to improve the gap between urban and rural areas. To improve the health-related quality of life of older adults in rural areas, it would be helpful to increase physical activity and to form a community, leading to a social network.

Clinical and cost-effectiveness of a personalised health promotion intervention enabling independence in older people with mild frailty (‘HomeHealth’) compared to treatment as usual: study protocol for a randomised controlled trial

Background

Frailty is clinically associated with multiple adverse outcomes, including reduced quality of life and functioning, falls, hospitalisations, moves to long-term care and mortality. Health services commonly focus on the frailest, with highest levels of need. However, evidence suggests that frailty is likely to be more reversible in people who are less frail. Evidence is emerging on what interventions may help prevent or reduce frailty, such as resistance exercises and multi-component interventions, but few interventions are based on behaviour change theory. There is little evidence of cost-effectiveness.

Previously, we co-designed a new behaviour change health promotion intervention (“HomeHealth”) to support people with mild frailty. HomeHealth is delivered by trained voluntary sector support workers over six months who support older people to work on self-identified goals to maintain their independence, such as strength and balance exercises, nutrition, mood and enhancing social engagement. The service was well received in our feasibility randomised controlled trial and showed promising effects upon outcomes.

Aim

To test the clinical and cost-effectiveness of the HomeHealth intervention on maintaining independence in older people with mild frailty in comparison to treatment as usual (TAU).

Methods

Single-blind individually randomised controlled trial comparing the HomeHealth intervention to TAU. We will recruit 386 participants from general practices and the community across three English regions. Participants are included if they are community-dwelling, aged 65 + , with mild frailty according to the Clinical Frailty Scale. Participants will be randomised 1:1 to receive HomeHealth or TAU for 6 months. The primary outcome is independence in activities of daily living (modified Barthel Index) at 12 months. Secondary outcomes include instrumental activities of daily living, quality of life, frailty, wellbeing, psychological distress, loneliness, cognition, capability, falls, carer burden, service use, costs and mortality. Outcomes will be analysed using linear mixed models, controlling for baseline Barthel score and site. A health economic analysis and embedded mixed-methods process evaluation will be conducted.

Discussion

This trial will provide definitive evidence on the effectiveness and cost-effectiveness of a home-based, individualised intervention to maintain independence in older people with mild frailty in comparison to TAU, that could be implemented at scale if effective.

Estimating an anchored utility tariff for the well-being of older people measure (WOOP) for the Netherlands

OBJECTIVE

Health economic evaluations using common health-related quality of life measures may fall short in adequately incorporating all relevant benefits of health and social care interventions targeted at older people. The Well-being of Older People measure (WOOP) is a broader well-being measure that comprises nine well-being domains. The objective of this study was to estimate a utility tariff for the WOOP, to facilitate its application in cost-utility analyses.

METHODS

A discrete choice experiment (DCE) with duration approach was set up and fielded among 2,012 individuals from the Netherlands aged 65 years and above. Matched pairwise choice tasks, colour-coding and level overlap were used to reduce the cognitive burden of the DCE. The choice tasks were created using a Bayesian heterogeneous D-efficient design. The estimation procedure accommodated for nonlinear time preferences via an exponential discounting function.

RESULTS

The estimation results showed that 'physical health', 'mental health', and 'making ends meet' were the most important well-being domains for older people, followed by 'independence' and 'living situation'. Of somewhat lesser importance were domains like 'social life', 'receiving support' and 'feeling useful'. The generated utility tariffs can be used to translate well-being states described with the WOOP to a utility score between -0.616 and 1.

CONCLUSIONS

This study established a tariff for the WOOP, which will facilitate its use in economic evaluations of health and social care interventions targeted at older people, first of all in the Netherlands.

Valuing informal carers' quality of life using best-worst scaling-Finnish preference weights for the Adult Social Care Outcomes Toolkit for carers (ASCOT-Carer)

This study developed Finnish preference weights for the seven-attribute Adult Social Care Outcomes Toolkit for carers (ASCOT-Carer) and investigated survey fatigue and learning in best-worst scaling (BWS) experiments. An online survey that included a BWS experiment using the ASCOT-Carer was completed by a sample from the general population in Finland. A block of eight BWS profiles describing different states from the ASCOT-Carer were randomly assigned to each respondent, who consecutively made four choices (best, worst, second best and second worst) per profile. The analysis panel data had 32,160 choices made by 1005 respondents. A scale multinomial logit (S-MNL) model was used to estimate preference weights for 28 ASCOT-Carer attribute levels. Fatigue and learning effects were examined as scale heterogeneity. Several specifications of the generalised MNL model were employed to ensure the stability of the preference estimates. The most and least-valued states were the top and bottom levels of the control over daily life attribute. The preference weights were not on a cardinal scale. We observed the position effect of the attributes on preferences associated with the best or second-best choices. A learning effect was found. The established preference weights can be used in evaluations of the effects of long-term care services and interventions on the quality of life of service users and caregivers. The learning effect implies a need to develop study designs that ensure equal consideration to all profiles (choice tasks) in a sequential choice experiment.

Cost analysis of employing general practitioners within residential aged care facilities based on a prospective, stepped-wedge, cluster randomised trial

OBJECTIVE

To assess the impacts of changing a model of care and employing general practitioners (GPs) within residential aged care facilities (RACFs) on costs to the aged care provider (ACP) and state and federal governments of Australia.

METHODS

This study was a cost analysis of a prospective, stepped-wedge, cluster randomised trial. All financial data from the ACP for every RACF involved, before and after implementation of the new model were obtained. Costs of hospital transfers, admissions, ambulance usage and GP consultations were calculated. Costs of new infrastructure, recruiting and training new staff were accounted for. Costs were standardised to 2019 Australian Dollars per occupied bed day (OBD).

RESULTS

Implementation of the new model of care resulted in overall cost savings of $9.7 per OBD to the ACP, with increased salary costs offset by increased federal government subsidies and Medicare claims income. Costs to the federal government increased by $19.6 per OBD, driven by increases in subsides. Costs savings of $3.0 per OBD to state governments were seen, driven by decreased costs of hospital transfers.

CONCLUSIONS

Implementation of a model of care including GPs employed at RACFs had a mixed impact on costs depending on perspective, with overall savings to the ACP and state government perspective.

Outpatient Oral Neuropathic Pain Management with Photobiomodulation Therapy: A Prospective Analgesic Pharmacotherapy-Paralleled Feasibility Trial

Neuropathic pain (NP) can be challenging to treat effectively as analgesic pharmacotherapy (MED) can reduce pain, but the majority of patients do not experience complete pain relief. Our pilot approach is to assess the feasibility and efficacy of an evidence-based photobiomodulation (PBM) intervention protocol. This would be as an alternative to paralleled standard analgesic MED for modulating NP intensity-related physical function and quality of life (QoL) prospectively in a mixed neurological primary burning mouth syndrome and oral iatrogenic neuropathy study population (n = 28). The study group assignments and outcome evaluation strategy/location depended on the individual patient preferences and convenience rather than on randomisation. Our prospective parallel study aimed to evaluate the possible pre/post-benefit of PBM and to allow for a first qualitative comparison with MED, various patient-reported outcome measures (PROMs) based on Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT-II) were used for up to a nine-month follow-up period in both intervention groups (PBM and MED). The PBM protocol applied to the PBM group was as follows: λ810 nm, 200 mW, 0.088 cm2, 30 s/point, 9 trigger and affected points, twice a week for five consecutive weeks, whereas the MED protocol followed the National Institute of Clinical Excellence (NICE) guidelines. Our results showed that despite the severe and persistent nature of the symptoms of 57.50 ± 47.93 months at baseline in the PBM group, a notably rapid reduction in PISmax on VAS from 7.6 at baseline (T0) to 3.9 at one-month post-treatment (T3) could be achieved. On the other hand, mean PISmax was only reduced from 8.2 at baseline to 6.8 at T3 in the MED group. Our positive PBM findings furthermore support more patients' benefits in improving QoL and functional activities, which were considerably impaired by NP such as: eating, drinking and tasting, whereas the analgesic medication regimens did not. No adverse events were observed in both groups. To the best knowledge of the authors, our study is the first to investigate PBM efficacy as a monotherapy compared to the gold standard analgesic pharmacotherapy. Our positive data proves statistically significant improvements in patient self-reported NP, functionality, psychological profile and QoL at mid- and end-treatment, as well as throughout the follow-up time points (one, three, six and nine months) and sustained up to nine months in the PBM group, compared to the MED group. Our study, for the first time, proves the efficacy and safety of PBM as a potent analgesic in oral NP and as a valid alternative to the gold standard pharmacotherapy approach. Furthermore, we observed long-term pain relief and functional benefits that indicate that PBM modulates NP pathology in a pro-regenerative manner, presumably via antioxidant mechanisms.

Predicting falls within 3 months of emergency department discharge among community-dwelling older adults using self-report tools versus a brief functional assessment

BACKGROUND

Identifying older adults with risk for falls prior to discharge home from the Emergency Department (ED) could help direct fall prevention interventions, yet ED-based tools to assist risk stratification are under-developed. The aim of this study was to assess the performance of self-report and functional assessments to predict falls in the 3 months post-ED discharge for older adults.

METHODS

A prospective cohort of community-dwelling adults age 60 years and older were recruited from one urban ED (N = 134). Participants completed: a single item screen for mobility (SIS-M), the 12-item Stay Independent Questionnaire (SIQ-12), and the Timed Up and Go test (TUG). Falls were defined through self-report of any fall at 1- and 3-months and medical record review for fall-related injury 3-months post-discharge. We developed a hybrid-convolutional recurrent neural network (HCRNN) model of gait and balance characteristics using truncal 3-axis accelerometry collected during the TUG. Internal validation was conducted using bootstrap resampling with 1000 iterations for SIS-M, FRQ, and GUG and leave-one-out for the HCRNN. We compared performance of M-SIS, FRQ, TUG time, and HCRNN by calculating the area under the receiver operating characteristic area under the curves (AUCs).

RESULTS

14 (10.4%) of participants met our primary outcome of a fall or fall-related injury within 3-months. The SIS-M had an AUC of 0.42 [95% confidence interval (CI) 0.19-0.65]. The SIQ-12 score had an AUC of 0.64 [95% confidence interval (CI) 0.49-0.80]. The TUG had an AUC of 0.48 (95% CI 0.29-0.68). The HCRNN model using generated accelerometer features collected during the TUG had an AUC of 0.99 (95% CI 0.98-1.00).

CONCLUSION

We found that self-report and functional assessments lack sufficient accuracy to be used in isolation in the ED. A neural network model using accelerometer features could be a promising modality but research is needed to externally validate these findings.

Economic Evaluation of a Reablement Training Program for Homecare Staff Targeting Sedentary Behavior in Community-Dwelling Older Adults Compared to Usual Care: A Cluster Randomized Controlled Trial

Purpose

Training and supporting homecare staff in reablement aims to change staff behavior from “doing for” to “doing with” older adults and is assumed to benefit the health and quality of life of older adults and reduce healthcare utilization and costs. This study evaluated the cost-effectiveness and cost-utility of the staff reablement training program “Stay Active at Home” (SAaH) from a societal perspective.

Participants and Methods

An economic evaluation was embedded in a 12-month cluster randomized controlled trial. Ten Dutch homecare nursing teams participated (n = 313 staff members), of which five teams were trained in reablement and the other five provided usual care. Cost and effect data were collected from 264 older adults at baseline, 6 and 12 months. Costs included “intervention,” “healthcare,” and “patient and family” costs (collectively, societal costs) and were assessed using questionnaires and client records or estimated by bottom-up micro-costing. Effects included sedentary behavior and quality-adjusted life years (QALYs). Multiple imputed bootstrapped data were used to generate cost-effectiveness planes and acceptability curves.

Results

No statistically significant differences were observed between the intervention and control group in terms of sedentary time (adjusted mean difference: \documentclass[12pt]{minimal} \usepackage{wasysym} \usepackage[substack]{amsmath} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage[mathscr]{eucal} \usepackage{mathrsfs} \DeclareFontFamily{T1}{linotext}{} \DeclareFontShape{T1}{linotext}{m}{n} {linotext }{} \DeclareSymbolFont{linotext}{T1}{linotext}{m}{n} \DeclareSymbolFontAlphabet{\mathLINOTEXT}{linotext} \begin{document} $$\beta $$ \end{document} 4.8 minutes [95% CI –26.4, 36.0]), QALYs (\documentclass[12pt]{minimal} \usepackage{wasysym} \usepackage[substack]{amsmath} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage[mathscr]{eucal} \usepackage{mathrsfs} \DeclareFontFamily{T1}{linotext}{} \DeclareFontShape{T1}{linotext}{m}{n} {linotext }{} \DeclareSymbolFont{linotext}{T1}{linotext}{m}{n} \DeclareSymbolFontAlphabet{\mathLINOTEXT}{linotext} \begin{document} $$\beta $$ \end{document} 0.01 [95% CI –0.03, 0.04]), and societal costs (\documentclass[12pt]{minimal} \usepackage{wasysym} \usepackage[substack]{amsmath} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage[mathscr]{eucal} \usepackage{mathrsfs} \DeclareFontFamily{T1}{linotext}{} \DeclareFontShape{T1}{linotext}{m}{n} {linotext }{} \DeclareSymbolFont{linotext}{T1}{linotext}{m}{n} \DeclareSymbolFontAlphabet{\mathLINOTEXT}{linotext} \begin{document} $$\beta $$ \end{document} €2216 [95% CI –459, 4895]), except lower costs for domestic help in the intervention group (\documentclass[12pt]{minimal} \usepackage{wasysym} \usepackage[substack]{amsmath} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage[mathscr]{eucal} \usepackage{mathrsfs} \DeclareFontFamily{T1}{linotext}{} \DeclareFontShape{T1}{linotext}{m}{n} {linotext }{} \DeclareSymbolFont{linotext}{T1}{linotext}{m}{n} \DeclareSymbolFontAlphabet{\mathLINOTEXT}{linotext} \begin{document} $$\beta $$ \end{document} €–173 [95% CI –299, –50]). The probability that SAaH was cost-effective compared to usual care ranged from 7.1% to 19.9%, depending on the willingness-to-pay (WTP) (€0‒€50,000)/minute of sedentary time averted and was 5.9% at a WTP of €20,000/QALY gained.

Conclusion

SAaH did not improve outcomes or reduce costs and was not cost-effective from a societal perspective compared to usual care in Dutch older adults receiving homecare. Consequently, there is insufficient evidence to justify widespread implementation of the training program in its current form.

The application of the QALY measure in the assessment of the effects of health interventions on an older population: a systematic scoping review

BACKGROUND

One of the most commonly used types of evaluation methods is cost-utility analysis (CUA), using the Quality Adjusted Life Year (QALY) indicator as a preference-based measure for assessing effects of a given programme. Such assessments are often translated into health-care provision priorities; therefore, effectively choosing the method of outcome evaluation is crucial for ensuring the best possible allocation of scarce resources. The main objective of this scoping review is to identify what kinds of problems and limitations may occur when the QALY indicator is used to assess the effects of health interventions in the older population.

METHODS

To identify literature in a scoping review, the databases MEDLINE via PubMed and Scopus were searched. A manual search on relevant organizations' and associations' websites was also conducted (EUnetHTA, ISPOR and national governmental agencies responsible for allocation decisions). No limits concerning publication dates were set. All relevant data were extracted and analyzed, then a narrative summary was prepared.

RESULTS

The database search identified 10,832 relevant items, finally 32 studies were included in the analysis. The main types of issues indicated in the studies were as follows: (1) lower life expectancy in the older population causes lower QALY gains; (2) an equal value of one QALY is used regardless of age; (3) poorer average health state causes lower QALY gains; (4) inadequate instruments to measure quality of life (QoL); (5) attributes of QoL used regardless of age; and (6) no beyond-health QoL aspects taken into account.

CONCLUSIONS

This review shows clearly that many problems of different types are connected with using QALY for the older population, but there is no consensus as to whether QALY discriminates against the older population or not - an opinion regarding this issue depends strongly on accepted principles, particularly the approach to equity and how one understands fairness. Health care resources should not be allocated solely on the basis of the health maximization rule because this can lead to discrimination against certain groups (e.g., older, disabled, and/or chronically ill people). To maintain the balance between efficiency and equity, the issues connected with age-based rationing should be widely discussed.

Systematic review of 29 self-report instruments for assessing quality of life in older adults receiving aged care services

BACKGROUND

Quality of life (QoL) outcomes are used to monitor quality of care for older adults accessing aged care services, yet it remains unclear which QoL instruments best meet older adults', providers' and policymakers' needs. This review aimed to (1) identify QoL instruments used in aged care and describe them in terms of QoL domains measured and logistical details; (2) summarise in which aged care settings the instruments have been used and (3) discuss factors to consider in deciding on the suitability of QoL instruments for use in aged care services.

DESIGN

Systematic review.

DATA SOURCES

MEDLINE, EMBASE, PsycINFO, Cochrane Library and CINAHL from inception to 2021.

ELIGIBILITY CRITERIA

Instruments were included if they were designed for adults (>18 years), available in English, been applied in a peer-reviewed research study examining QoL outcomes in adults >65 years accessing aged care (including home/social care, residential/long-term care) and had reported psychometrics.

DATA EXTRACTION AND SYNTHESIS

Two researchers independently reviewed the measures and extracted the data. Data synthesis was performed via narrative review of eligible instruments.

RESULTS

292 articles reporting on 29 QoL instruments were included. Eight domains of QoL were addressed: physical health, mental health, emotional state, social connection, environment, autonomy and overall QoL. The period between 1990 and 2000 produced the greatest number of newly developed instruments. The EuroQoL-5 Dimensions (EQ-5D) and Short Form-series were used across multiple aged care contexts including home and residential care. More recent instruments (eg, ICEpop CAPability measure for Older people (ICECAP-O) and Adult Social Care Outcomes Toolkit (ASCOT)) tend to capture emotional sentiment towards personal circumstances and higher order care needs, in comparison with more established instruments (eg, EQ-5D) which are largely focused on health status.

CONCLUSIONS

A comprehensive list of QoL instruments and their characteristics is provided to inform instrument choice for use in research or for care quality assurance in aged care settings, depending on needs and interests of users.

Feasibility of the EQ-5D in the elderly population: a systematic review of the literature

Purpose

The EQ-5D-3L and 5L are widely used generic preference-based instruments, which are psychometrically sound with the general population, but little is known about the instruments’ feasibility in the elderly. Therefore, this systematic review summarises the available literature with regard to the feasibility properties of the instruments in the elderly population.

Methods

We conducted a systematic search in PubMed, PsycInfo and EuroQol databases using pre-specified vocabulary and inclusion/exclusion criteria to identify publications until November 2020. Study characteristics and outcomes referring to the feasibility of the EQ-5D-3L and 5L in the elderly were extracted, if all study participants were at least 65+ years.

Results

We identified 17 studies reporting feasibility outcomes based on four criteria: missing values, completion rates, completion time and broad qualitative statements referring to the completion. Missing values per dimension ranged from 0 to 10.7%, although being mostly below 7%. The completion rate was around 90% or better, whereas the EQ VAS rating was missing from 2.3 to 25.3% of the respondents. Only two of the included studies examined the EQ-5D-5L; 15 studies reported on the EQ-5D-3L.

Conclusion

Comparing our findings against the general population from published literature, we find that feasibility outcomes in older age groups are just below that of younger populations. Furthermore, older respondents have a higher propensity of requiring assistance or even an interviewer-based approach. Nonetheless, the reviewed literature indicates that the EQ-5D-3L still has good feasibility properties and, hence, is highly applicable in older respondents. However, further research is needed to explore feasibility properties of the EQ-5D-5L in this population.

Convergent and Discriminant Validity of the Barthel Index and the EQ-5D-3L When Used on Older People in a Rehabilitation Setting

This study compares the empirical performance of a commonly used functional-status measure, the Barthel Index (BI), to that of a widely used generic preference-based instrument, the EuroQoL-5-Dimensions 3 Level (EQ-5D-3L), in older people. Data from older people receiving rehabilitation services were used to test the validity of the BI and EQ-5D-3L. Convergent validity was investigated using Spearman’s correlation, exploratory factor analysis (EFA), scatter plots, Krippendorff’s alpha and modified Bland-Altman plots. Discriminant validity was examined using Kruskal Wallis tests, ceiling effects and EFA. A total of 1690 participants were included in the analysis. The BI total and EQ-5D-3L utility scores showed moderate correlation (r = 0.51; Krippendorff’s alpha = 0.52). Kendall’s Tau-B correlations between BI items and EQ-5D-3L dimensions measuring the same construct were weak to moderate (0.05 ≤ absolute r ≤ 0.54). In the EFA, some BI items cross-loaded onto the same factors as EQ-5D-3L dimensions, suggesting that the instruments were interrelated. The BI, however, focuses more on physical functioning, while the EQ-5D-3L measures broader wellbeing concepts. Both instruments showed good discriminant validity and would therefore be equally valuable for measuring subgroup differences. Researchers should consider using the BI in rehabilitation to capture more physical functioning-specific constructs not measured by the EQ-5D-3L.

Acceptance and commitment therapy for older people with treatment-resistant generalised anxiety disorder: the FACTOID feasibility study

BACKGROUND

Generalised anxiety disorder, characterised by excessive anxiety and worry, is the most common anxiety disorder among older people. It is a condition that may persist for decades and is associated with numerous negative outcomes. Front-line treatments include pharmacological and psychological therapy, but many older people do not find these treatments effective. Guidance on managing treatment-resistant generalised anxiety disorder in older people is lacking.

OBJECTIVES

To assess whether or not a study to examine the clinical effectiveness and cost-effectiveness of acceptance and commitment therapy for older people with treatment-resistant generalised anxiety disorder is feasible, we developed an intervention based on acceptance and commitment therapy for this population, assessed its acceptability and feasibility in an uncontrolled feasibility study and clarified key study design parameters.

DESIGN

Phase 1 involved qualitative interviews to develop and optimise an intervention as well as a survey of service users and clinicians to clarify usual care. Phase 2 involved an uncontrolled feasibility study and qualitative interviews to refine the intervention.

SETTING

Participants were recruited from general practices, Improving Access to Psychological Therapies services, Community Mental Health Teams and the community.

PARTICIPANTS

Participants were people aged ≥ 65 years with treatment-resistant generalised anxiety disorder.

INTERVENTION

Participants received up to 16 one-to-one sessions of acceptance and commitment therapy, adapted for older people with treatment-resistant generalised anxiety disorder, in addition to usual care. Sessions were delivered by therapists based in primary and secondary care services, either in the clinic or at participants' homes. Sessions were weekly for the first 14 sessions and fortnightly thereafter.

MAIN OUTCOME MEASURES

The co-primary outcome measures for phase 2 were acceptability (session attendance and satisfaction with therapy) and feasibility (recruitment and retention). Secondary outcome measures included additional measures of acceptability and feasibility and self-reported measures of anxiety, worry, depression and psychological flexibility. Self-reported outcomes were assessed at 0 weeks (baseline) and 20 weeks (follow-up). Health economic outcomes included intervention and resource use costs and health-related quality of life.

RESULTS

Fifteen older people with treatment-resistant generalised anxiety disorder participated in phase 1 and 37 participated in phase 2. A high level of feasibility was demonstrated by a recruitment rate of 93% and a retention rate of 81%. A high level of acceptability was found with respect to session attendance (70% of participants attended ≥ 10 sessions) and satisfaction with therapy was adequate (60% of participants scored ≥ 21 out of 30 points on the Satisfaction with Therapy subscale of the Satisfaction with Therapy and Therapist Scale-Revised, although 80% of participants had not finished receiving therapy at the time of rating). Secondary outcome measures and qualitative data further supported the feasibility and acceptability of the intervention. Health economic data supported the feasibility of examining cost-effectiveness in a future randomised controlled trial. Although the study was not powered to examine clinical effectiveness, there was indicative evidence of improvements in scores for anxiety, depression and psychological flexibility.

LIMITATIONS

Non-specific therapeutic factors were not controlled for, and recruitment in phase 2 was limited to London.

CONCLUSIONS

There was evidence of high levels of feasibility and acceptability and indicative evidence of improvements in symptoms of anxiety, depression and psychological flexibility. The results of this study suggest that a larger-scale randomised controlled trial would be feasible to conduct and is warranted.
