Further Evidence of Feasibility, Validity, and Reliability of Quality of Life-Aged Care Consumers: Evidence From Home-Based Care Settings.

OBJECTIVES: The Quality of Life-Aged Care Consumers (QOL-ACC) is an aged-care-specific preference-based instrument currently being rolled out in residential care across Australia as part of the aged care Quality Indicator program. This study aimed to provide a comprehensive assessment of the feasibility, reliability, and construct validity of the QOL-ACC in a large national sample of older adults receiving aged care services at home. METHODS: Older adults receiving in-home aged care services completed a survey including the QOL-ACC, Quality of Care Experience-ACC, adult social care outcome tool, EQ-5D-5L, and 2 global single item measures of health and quality of life. Feasibility was assessed by missing responses (≤5%) and ceiling/floor effects (≤15%). Construct validity was assessed by exploring the relationship between the QOL-ACC and other instruments (convergent validity) and its ability to discriminate varying levels of self-rated health and quality of life (known-group validity). RESULTS: A total of 802 respondents (mean age, 74.5 ± 6.3 years; 56.0% females) completed the survey. The QOL-ACC had no missing responses, no floor effects, and very low ceiling effect (3.5%) and demonstrated moderate correlation with adult social care outcome tool (r = 0.59, P < .001), EQ-5D-5L (r = 0.65, P < .001), EQ-VAS (r = 0.53, P < .001), and a lower correlation with the QCE-ACC (r = 0.41, P < .001). Respondents with poor self-rated health and quality of life had significantly lower preference-weighted scores on the QOL-ACC. CONCLUSIONS: The QOL-ACC demonstrated adequate feasibility, reliability, and construct validity in a large population of older people accessing government-subsidized aged care services at home. Further studies will explore the responsiveness of the QOL-ACC to aged-care-specific interventions both in home and residential aged care settings.

The process of co-designing a model of social prescribing: An Australian case study.

INTRODUCTION: Social needs such as housing, employment, food, income and social isolation are having a significant impact on individuals, families and communities. Individuals are increasingly presenting to health settings with social needs, which are ill-equipped to address nonmedical needs. Social prescribing is a systematic approach connecting the health, social and community sectors to better address social needs and improve health and wellbeing. Social prescribing interventions are being implemented world-wide. With variability in health and social care systems internationally, it is important that social prescribing interventions are co-designed with key stakeholders to ensure they can be implemented and sustained within local systems. METHODS: This Australian case study provides a detailed description of the process undertaken to co-design a social prescribing service model in a regional area. Four co-design workshops were undertaken, two with health and social care professionals and two with community members. The project followed an iterative process of resourcing, planning, recruiting, sensitising, facilitation, reflection and building for change across the workshops. RESULTS: Through this process, key stakeholders were able to successfully co-design a social prescribing model of care for the region. CONCLUSION: By demonstrating the process and materials used in our project, we aim to open the 'black box' of co-design for social prescribing and provide ideas and resources for others to adapt and utilise. PATIENT OR PUBLIC CONTRIBUTION: The project was designed and undertaken by a steering committee comprising university-based researchers (authors C. O. and S. B.), local government (author D. A.) and health, social and community services (authors B. G., M. W., J. O. and S. R.). Members of the steering committee participated in project design, participant recruitment, workshop facilitation, data analysis and interpretation.

Reliability of the quality of life-aged care consumers (QOL-ACC) and EQ-5D-5L among older people using aged care services at home.

PURPOSE: The Quality of Life-Aged Care Consumers (QOL-ACC), a valid preference-based instrument, has been rolled out in Australia as part of the National Quality Indicator (QI) program since April 2023 to monitor and benchmark the quality of life of aged care recipients. As the QOL-ACC is being used to collect quality of life data longitudinally as one of the key aged care QI indicators, it is imperative to establish the reliability of the QOL-ACC in aged care settings. Therefore, we aimed to assess the reliability of the QOL-ACC and compare its performance with the EQ-5D-5L. METHODS: Home care recipients completed a survey including the QOL-ACC, EQ-5D-5L and two global items for health and quality of life at baseline (T1) and 2 weeks later (T2). Using T1 and T2 data, the Gwet's AC2 and intra-class correlation coefficient (ICC) were estimated for the dimension levels and overall scores agreements respectively. The standard error of measurement (SEM) and the smallest detectable change (SDC) were also calculated. Sensitivity analyses were conducted for respondents who did not change their response to global item of quality of life and health between T1 and T2. RESULTS: Of the 83 respondents who completed T1 and T2 surveys, 78 respondents (mean ± SD age, 73.6 ± 5.3 years; 56.4% females) reported either no or one level change in their health and/or quality of life between T1 and T2. Gwet's AC2 ranged from 0.46 to 0.63 for the QOL-ACC dimensions which were comparable to the EQ-5D-5L dimensions (Gwet's AC2 ranged from 0.52 to 0.77). The ICC for the QOL-ACC (0.85; 95% CI, 0.77-0.90) was comparable to the EQ-5D-5L (0.83; 95% CI, 0.74-0.88). The SEM for the QOL-ACC (0.08) was slightly smaller than for the EQ-5D-5L (0.11). The SDC for the QOL-ACC and the EQ-5D-5L for individual subjects were 0.22 and 0.30 respectively. Sensitivity analyses stratified by quality of life and health status confirmed the base case results. CONCLUSIONS: The QOL-ACC demonstrated a good test-retest reliability similar to the EQ-5D-5L, supporting its repeated use in aged care settings. Further studies will provide evidence of responsiveness of the QOL-ACC to aged care-specific interventions in aged care settings.

Age-related differences in saccadic indices of top-down guidance via short-term memory during visual search.

Aging has been associated with significant declines in the speed and accuracy of visual search. These effects have been attributed partly to low-level (bottom-up) factors including reductions in sensory acuity and general processing speed. Aging is also associated with changes in top-down attentional control, but the impact of these on search is less well-understood. The present study investigated age-related differences in top-down attentional control by comparing the speed and accuracy of saccadic sampling in the presence and absence of top-down information about target color in young (YA) and older (OA) observers. Displays contained an equal number of red and blue Landholt stimuli. Targets were distinguished from distractors by a unique orientation, and observers reported the direction of the target's gap on each trial. Single-target cues signaled the color of the target with 100% validity. Dual-target cues indicated the target could be present in either colored subgroup. The results revealed reliable group differences in the benefits associated with top-down information on single-target cues compared to dual-target cues. On single-target searches, OA made significantly more saccades than YA to stimuli in the uncued color subset. Single-target cues also produced a smaller advantage in the time taken to fixate the target in OA compared to YA. These results support an age-related decline in observers' use of top-down information to restrict sequences of saccades to a task-relevant subset of objects during visual search.

Clinical effectiveness of cardiac rehabilitation and barriers to completion in patients of low socioeconomic status in rural areas: A mixed-methods study.

OBJECTIVE: To investigate cardiac rehabilitation utilisation and effectiveness, factors, needs and barriers associated with non-completion. DESIGN: We used the mixed-methods design with concurrent triangulation of a retrospective cohort and a qualitative study. SETTING: Economically disadvantaged areas in rural Australia. PARTICIPANTS: Patients (≥18 years) referred to cardiac rehabilitation through a central referral system and living in rural areas of low socioeconomic status. MAIN MEASURES: A Cox survival model balanced by inverse probability weighting was used to assess the association between cardiac rehabilitation utilization and 12-month mortality/cardiovascular readmissions. Associations with non-completion were tested by logistic regression. Barriers and needs to cardiac rehabilitation completion were investigated through a thematic analysis of semi-structured interviews and focus groups (n = 28). RESULTS: Among 16,159 eligible separations, 44.3% were referred, and 11.2% completed cardiac rehabilitation. Completing programme (HR 0.65; 95%CI 0.57-0.74; p < 0.001) led to a lower risk of cardiovascular readmission/death. Living alone (OR 1.38; 95%CI 1.00-1.89; p = 0.048), having diabetes (OR 1.48; 95%CI 1.02-2.13; p = 0.037), or having depression (OR 1.54; 95%CI 1.14-2.08; p = 0.005), were associated with a higher risk of non-completion whereas enrolment in a telehealth programme was associated with a lower risk of non-completion (OR 0.26; 95%CI 0.18-0.38; p < 0.001). Themes related to logistic issues, social support, transition of care challenges, lack of care integration, and of person-centeredness emerged as barriers to completion. CONCLUSIONS: Cardiac rehabilitation completion was low but effective in reducing mortality/cardiovascular readmissions. Understanding and addressing barriers and needs through mixed methods can help tailor cardiac rehabilitation programmes to vulnerable populations and improve completion and outcomes.

Examining interrater agreement between self-report and proxy-report responses for the quality of life-aged care consumers (QOL-ACC) instrument.

BACKGROUND: Quality of life is an important quality indicator for health and aged care sectors. However, self-reporting of quality of life is not always possible given the relatively high prevalence of cognitive impairment amongst older people, hence proxy reporting is often utilised as the default option. Internationally, there is little evidence on the impact of proxy perspective on interrater agreement between self and proxy report. OBJECTIVES: To assess the impacts of (i) cognition level and (ii) proxy perspective on interrater agreement using a utility instrument, the Quality of Life-Aged Care Consumers (QOL-ACC). METHODS: A cross-sectional study was undertaken with aged care residents and family member proxies. Residents completed the self-report QOL-ACC, while proxies completed two proxy versions: proxy-proxy perspective (their own opinion), and proxy-person perspective (how they believe the resident would respond). Interrater agreement was assessed using quadratic weighted kappas for dimension-level data and concordance correlation coefficients and Bland-Altman plots for utility scores. RESULTS: Sixty-three residents (22, no cognitive impairment; 41, mild-to-moderate cognitive impairment) and proxies participated. In the full sample and in the mild-to-moderate impairment group, the mean self-reported QOL-ACC utility score was significantly higher than the means reported by proxies, regardless of perspective (p < 0.01). Agreement with self-reported QOL-ACC utility scores was higher when proxies adopted a proxy-person perspective. CONCLUSION: Regardless of cognition level and proxy perspective, proxies tend to rate quality of life lower than residents. Further research is needed to explore the impact of such divergences for quality assessment and economic evaluation in aged care.

Exploring older people's understanding of the QOL-ACC, a new preference-based quality-of-life measure, for quality assessment and economic evaluation in aged care: the impact of cognitive impairment and dementia.

BACKGROUND: Quality-of-life is an essential outcome for quality assessment and economic evaluation in health and social care. The-Quality-of-Life - Aged Care Consumers (QOL-ACC) is a new preference-based quality-of-life measure, psychometrically validated with older people in aged care. More evidence is needed to inform the self-report reliability of the QOL-ACC in older people with varying levels of cognitive impairment and dementia. METHODS: A think-aloud protocol was developed and applied with older residents. The Mini Mental State Examination (MMSE) was applied to assign participants to no cognitive impairment (NCI - MMSE score ≥ 27) and cognitive impairment (MMCI - MMSE score < 27) subgroups. Three independent raters utilised a Tourangeau survey response model-based framework to identify response issues. Data were compared across cognition subgroups and synthesized using a 'traffic light' grading to classify frequency and type of response issues. Gradings were utilised to assess self-report reliability according to different levels of cognitive impairment. RESULTS: Qualitative data from 44 participants (NCI = 20, MMCI = 24) were included for analysis. Response issues were more evident in the cognitive impairment subgroup than the no cognitive impairment subgroup. All participants who received a 'red' grade had an MMSE score of < 20 and 66% of 'amber' grades occurred in the cognitive impairment subgroup. CONCLUSIONS: The QOL-ACC is able to be completed reliably by older residents with an MMSE score > 17. Future research is needed to assess the generalisability of these findings to other preference-based quality of life instruments and for older people in other care settings including health systems.

What Aspects of Quality of Life are Important from Palliative Care Patients' Perspectives? A Framework Analysis to Inform Preference-Based Measures for Palliative and End-of-Life Settings.

BACKGROUND AND OBJECTIVE: Preference-based outcome measures are commonly applied in economic analyses to inform healthcare resource allocation decisions. Few preference-based outcome measures have been specifically developed for palliative and end-of-life settings. This study aimed to identify which quality-of-life domains are most important to Australians receiving specialised palliative care services to help determine if the development of a new condition-specific preference-based outcome measure is warranted. METHODS: In-depth face-to-face interviews were conducted with 18 participants recruited from palliative care services in South Australia. Data were analysed using a framework analysis drawing on findings from a systematic review of international qualitative studies investigating the quality-of-life preferences of patients receiving palliation (domains identified included cognitive, emotional, healthcare, personal autonomy, physical, preparatory, social, spiritual). Participants identified missing or irrelevant domains in the EQ-5D and QLU-C10D questionnaires and ranked the importance of domains. RESULTS: A priori domains were refined into cognitive, environmental, financial, independence, physical, psychological, social and spiritual. The confirmation of the eight important quality-of-life domains across multiple international studies suggests there is a relatively high degree of convergence on the perspectives of patients in different countries. Four domains derived from the interviews are not covered by the EQ-5D and QLU-C10D (cognitive, environmental, financial, spiritual), including one of the most important (spiritual). CONCLUSIONS: Existing, popular, preference-based outcome measures such as the EQ-5D do not incorporate the most important, patient-valued, quality-of-life domains in the palliative and end-of-life settings. Development of a new, more relevant and comprehensive preference-based outcome measure could improve the allocation of resources to patient-valued services and have wide applicability internationally.

Characteristics of patients who return unplanned to the ED, and factors that contribute to their decision to return: Integrated results from an explanatory sequential mixed methods inquiry.

AIM: To identify common characteristics of patients who return to the ED unplanned and factors that may contribute to their decision to return. BACKGROUND: Return visits to the Emergency Department (ED) have been associated with adverse events and deficits in initial care provided. There is increasing evidence to suggest that many return visits may be preventable. METHODS: The results of primary quantitative measures (QUAN) followed by qualitative measures (qual) were integrated to build on and explain the quantitative data found in the initial phase of the research. RESULTS: Integration of results produced three new findings. 1) Most return visits occurred beyond 48 hrs because patients intentionally delayed going back to the ED despite their persisting symptoms; 2) Clinical urgency and deterioration were rarely evident in patients who made return visits in patients and 3) Ineffective communication between the clinician and the patient at discharge may have contributed to patients making the decision to return to the ED. CONCLUSION: The decision to return unplanned to the ED is not an immediate response for most patients, and several potentially avoidable factors may influence their decision-making process. Future research should focus on strategies which contribute to the avoidance of unplanned return visits.

Unravelling the Self-Report Versus Proxy-Report Conundrum for Older Aged Care Residents: Findings from a Mixed-Methods Study.

OBJECTIVES: No guidance currently exists as to the cognition threshold beyond which self-reported quality of life for older people with cognitive impairment and dementia is unreliable. METHODS: Older aged care residents (≥ 65 years) were randomly assigned to complete the EQ-5D-5L in computer-based (eye movements were tracked) or hard copy (participants were encouraged to 'think aloud') format. Cognition was assessed using the Mini-Mental State Examination (MMSE). Think aloud and eye tracking data were analysed by two raters, blinded to MMSE scores. At the participant level, predefined criteria were used to assign traffic light grades (green, amber, red). These grades indicate the extent to which extracted data elements provided evidence of self-report reliability. The MMSE-defined cognition threshold was determined following review of the distributions of assigned traffic light grades. RESULTS: Eighty-one residents participated and provided complete data (38 eye tracking, 43 think aloud). In the think aloud cohort, all participants with an MMSE score ≤ 23 (n = 10) received an amber or red grade, while 64% of participants with an MMSE score ≥ 24 (21 of 33) received green grades. In the eye tracking cohort, 68% of participants with an MMSE score ≥ 24 (15 of 22) received green grades. Of the 16 eye tracking participants with an MMSE score ≤ 23, 14 (88%) received an amber or red grade. CONCLUSIONS: Most older residents with an MMSE score ≥ 24 have sufficient cognitive capacity to self-complete the EQ-5D-5L. More research is needed to better understand self-completion reliability for other quality-of-life instruments in cognitively impaired populations.

The experience of using home automation by individuals with disability.

Purpose: People with disability often require long-term support within the home. Advances in technology have made home automation more readily available to support people living with disability. However, few studies describe the perspectives of people using home automation. The aim of this study was to explore the experience of individuals living with long term serious disability using home automation.Materials and methods: A phenomenological approach was adopted. In-depth, semi-structured interviews were conducted. Data were analysed using an inductive approach to identify themes.Results: Two overarching categories of themes were identified: 'benefits' and 'challenges'. Benefits captured the outcomes experienced by people living with disability using home automation and the impact upon their lives. Participants described several challenges with using home automation such as self-advocating to receive home automation, long waiting periods in the assessment and installation process, frustrations when home automation did not work, and the challenges experienced from being without home automation.Conclusion: This research identified the benefits and challenges of home automation experienced by people with long term serious disability. The findings can be used to understand the importance of home automation and the impact it has upon the lives of people living with disability.

It is recognised that home automation can have a positive impact upon the lives of people living with disability.Funding for home automation is a complicated process with long waiting times. This process needs to be readdressed in order for people to receive home automation in a timely manner to prevent negative experiences.Home automation within the community could support people living with disability to access the community more.It is important to develop facilities and communities that are accessible and inclusive for people with disabilities.

How do older adults receiving aged care services understand and respond to the EQ-5D-5L? A think-aloud study in residential care.

PURPOSE: The EQ-5D-5L is a preference-based instrument for measuring and valuing health-related quality of life (HRQoL). The EQ-5D-5L has been used extensively in economic evaluation, including in aged care. However, older adults' understanding of the EQ-5D-5L has not been comprehensively investigated to date. This research aimed to assess older adults' understanding of the EQ-5D-5L using a think-aloud protocol with two cognition groups: no cognitive impairment and mild/moderate cognitive impairment. METHODS: Participants' cognition was assessed using the Standardised Mini-Mental State Examination (SMMSE). Face-to face interviews were conducted with concurrent and retrospective think-aloud encouraged through verbal probing. Audio recordings were transcribed, and qualitative analysis, informed by the Tourangeau four-stage Response Model (comprehension, retrieval, decision process, response process) was conducted in NVivo. RESULTS: In total, 46 older adults (age 65 +) were recruited from 10 residential care facilities across South Australia (n = 25 no cognitive impairment, n = 21 mild/moderate cognitive impairment). Comprehension, retrieval, judgement and response mapping issues were common across all cognition levels and EQ-5D-5L dimensions. The two dimensions resulting in the most response issues were usual activities and personal care. CONCLUSION: Older adults may bring a different understanding to the EQ-5D-5L descriptive system than that expected given testing with general population samples. Dimension descriptors that are more relevant to this population may facilitate responses that better align with the underlying EQ-5D-5L concept model.

A scoping review of the use of visual tools and adapted easy-read approaches in Quality-of-Life instruments for adults.

PURPOSE: Self-Reporting using traditional text-based Quality-of-Life (QoL) instruments can be difficult for people living with sensory impairments, communication challenges or changes to their cognitive capacity. Adapted communication techniques, such as Easy-Read techniques, or use of pictures could remove barriers to participation for a wide range of people. This review aimed to identify published studies reporting adapted communication approaches for measuring QoL, the methodology used in their development and validation among adult populations. METHODS: A scoping review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews checklist was undertaken. RESULTS: The initial search strategy identified 13,275 articles for screening, with 264 articles identified for full text review. Of these 243 articles were excluded resulting in 21 studies for inclusion. The majority focused on the development of an instrument (12 studies) or a combination of development with some aspect of validation or psychometric testing (7 studies). Nineteen different instruments were identified by the review, thirteen were developed from previously developed generic or condition-specific quality of life instruments, predominantly aphasia (7 studies) and disability (4 studies). Most modified instruments included adaptations to both the original questions, as well as the response categories. CONCLUSIONS: Studies identified in this scoping review demonstrate that several methods have been successfully applied e.g. with people living with aphasia post-stroke and people living with a disability, which potentially could be adapted for application with more diverse populations. A cohesive and interdisciplinary approach to the development and validation of communication accessible versions of QOL instruments, is needed to support widespread application, thereby reducing reliance on proxy assessors and promoting self-assessment of QOL across multiple consumer groups and sectors.

A scoping review to explore the health, social and economic outcomes of home automation for people with disability.

PURPOSE: People with disability often require long-term care. Long-term care is changing with the availability and advances in cost and function of technologies, such as home automation. Home automation has the potential to reduce paid carer hours and can potentially offer many benefits to people with a disability. The aim of this scoping review is to identify the health, social and economic outcomes experienced by people living with a disability who use home automation. MATERIALS AND METHODS: Two electronic databases were searched by title and abstract to identify international literature that describes home automation experiences from the perspectives of people with disability. A thematic approach was taken to synthesise the data to identify the key outcomes from home automation. RESULTS: The review identified 11 studies reporting home automation outcomes for people living with a disability. Seven outcomes were associated with home automation: independence, autonomy, participation in daily activities, social and community connectedness, safety, mental health, and paid care and informal care. CONCLUSION: Advances in technology and changes in funding to support people living with a disability have made access to home automation more readily available. Overall, the study findings showed that there is a range of potential benefits of home automation experienced by individuals living with a disability.Implications for RehabilitationA wide range of outcomes have been evaluated following the installation of home automation systems for people with disability.Key outcomes evaluated to date include independence, autonomy, participation, safety, mental health, and reduced need for paid carers.Outcomes of home automation appear to be connected; for example, improved participation may lead to improved mental health.

Patients' experiences and reasons for unplanned return visits to the emergency department: A qualitative study.

AIMS: The aim of this study was to explore the reasons for and experiences of patients who make an unplanned return visit to the emergency department. DESIGN: This study forms the qualitative phase of a larger explanatory sequential mixed methods study and is informed by interpretive description. The paper was prepared using the consolidated criteria for reporting qualitative research. METHODS: Semi-structured patient interviews were conducted over a 3-month period (July-September 2021). Data were analysed using reflexive thematic analysis. RESULTS: Interviews from 13 participants generated findings related to experiences at and following their initial visit that contributed to their decision to return to the emergency department. Four themes were developed: (1) Patients experience barriers to feeling heard and having their concerns addressed; (2) Patients have little choice but to place their trust in clinicians; (3) Patients unexpectedly experience persistent symptoms which cannot be managed at home; and (4) Patients develop a sense of urgency about having their condition treated. CONCLUSION: A negative experience at the initial ED visit may have dual conflicting impacts. It can contribute to patients' perceived need for a return visit because they are ill-equipped to manage their condition at home, and it can also contribute to their initial reluctance to return to the ED when symptoms persist. Nurses and other clinicians working in ED need to actively build patient's experiential trust through clear communication, timely consultation and shared decision-making at discharge, which in turn can increase patient's confidence and capability to self-manage their condition. This study adds to the current body of literature about return visits by highlighting that a more positive experience of ED may assist patients to make better-informed decisions about when and how to seek treatment and minimize unnecessary and unplanned return visits. Whilst not an intended topic for exploration in this study, the COVID-19 pandemic influenced patients' experiences at both initial and return ED visits and limited their ability to access primary healthcare options. These experiences contributed to patients' decisions to make a return visit.

Older adults' community participation, physical activity, and social interactions during and following COVID-19 restrictions in Australia: a mixed methods approach.

BACKGROUND: With the increasing age of the global population, key components of healthy ageing including community, physical, and social participation continue to gain traction. However, management of the COVID-19 pandemic aimed to protect older adults and reduce the spread of the virus, this restricted community participation and reduced the opportunities for social interaction. METHODS: This mixed methods study investigates community dwelling older adults' community participation; physical activity and social interaction prior to, during, and following the COVID-19 lockdown in Adelaide, Australia. Twenty-six community dwelling older adults were monitored over three time-points between November 2018 and October 2020, with Global Positioning Systems, accelerometry and self-reported diaries. In addition, nineteen participants completed semi-structured interviews. RESULTS: Community participation varied across the three time points, with significant reduction in the number of trips taken out-of-home (p = 0.021), social interactions (p = 0.001) and sleep quality (p = 0.008) during restrictions. Five themes were identified to explain personal experiences of community participation during restrictions: (1) Reframing of meaning, (2) Redefining to maintain activities, (3) Revision of risk, (4) Reflection and renewal and (5) Future planning. CONCLUSION: During COVID-19 the physical and social activities of community dwelling older adults changed. Services that support older adults to adapt their activities   , considering their capacities and preferences, to facilitate community participation are required.

What Quality-of-Life Dimensions Are Most Important to Older Adults from Culturally and Linguistically Diverse Backgrounds Receiving Aged Care Services? An Exploratory Study.

There is little research on what aspects of quality of life (QoL) are most important to culturally and linguistically diverse (CALD) older adults. This study aimed to identify what QoL dimensions were most important to CALD older adults receiving aged care services, and therefore, how relevant a new six dimensions QoL instrument developed for use in aged care is to this population. A three-stage, mixed-methods study was undertaken. Stage 1: n = 3 focus groups with aged care providers. Stage 2: n = 30 semi-structured interviews with Italian-born older adults in ethno-specific residential aged care. Stage 3: survey of n = 63 older adults from mixed CALD backgrounds receiving community aged care services. Overall, older adults asserted the importance of the six dimensions of the new QoL instrument. The importance of 'identity' and 'purpose and meaning' were identified via the focus groups; however, the community-based CALD older adults identified these aspects of quality of life as more important than older Italians in residential care. Being in ethno-specific residential aged care where needs relating to language, food, and religion were met and they continued to live with others from their community may have meant that the meeting of cultural needs was more taken for granted.

Home Automation for Adults With Disability Following an Injury: Protocol for a Social Return on Investment Study.

BACKGROUND: People with disability following a serious injury require long-term care. The most common injuries resulting in long-term disability are spinal cord and acquired brain injuries. While the long-term effects are difficult to predict and will vary between individuals, the costs of care and recovery span well beyond the initial treatment phase and include long-term care. Long-term care is changing with the availability and advances in cost and function of technologies, such as home automation. "Home automation" refers to technology that automates or remotely controls household functions. Home automation costs vastly differ, but home automation has the potential to positively impact the lives of people with disabilities. However, there is a dearth of evidence relating to the impact of home automation for people with a disability and few rigorous evaluations about the costs and return on investment. OBJECTIVE: The purpose of this study is to describe the impact of home automation for people with long-term disability following a serious injury (such as a motor vehicle accident) using case studies, and by conducting an evaluation of the costs and outcomes for individuals, families, and the wider community using a Social Return on Investment (SROI) approach. METHODS: SROI is a form of economic evaluation that develops a theory of change to examine the relationship among inputs, outputs, and outcomes and, in recent years, has gained popularity internationally, including in Australia. SROI has six phases: (1) identify scope and stakeholders, (2) map outcomes, (3) evidence outcomes and give them value, (4) establish impact, (5) calculate the SROI, and (6) report findings. Individuals with a disability who use home automation and key stakeholders will be interviewed. Stakeholders will be individuals involved in home automation for people with disabilities, such as allied health professionals, medical practitioners, equipment suppliers, engineers, and maintenance professionals. Users of home automation will be people who have a disability following a serious injury, have the capacity to provide consent, and have 1 or more elements of home automation. The impact of home automation will be established with financial proxies and appropriate discounts applied to avoid overestimating the social return. The SROI ratio will be calculated, and findings will be reported. RESULTS: The project was funded in November 2021 by the Lifetime Support Authority. Recruitment is underway, and data collection is expected to be completed by October 2022. The final results of the study will be published in March 2023. CONCLUSIONS: To our knowledge, this study represents the first study in Australia and internationally to employ SROI to estimate the social, personal, and community outcomes of home automation for people with a disability following a serious injury. This research will provide valuable information for funders, consumers, researchers, and the public to guide and inform future decision-making.

A genome-wide association study of plasma concentrations of warfarin enantiomers and metabolites in sub-Saharan black-African patients.

Diversity in pharmacogenomic studies is poor, especially in relation to the inclusion of black African patients. Lack of funding and difficulties in recruitment, together with the requirement for large sample sizes because of the extensive genetic diversity in Africa, are amongst the factors which have hampered pharmacogenomic studies in Africa. Warfarin is widely used in sub-Saharan Africa, but as in other populations, dosing is highly variable due to genetic and non-genetic factors. In order to identify genetic factors determining warfarin response variability, we have conducted a genome-wide association study (GWAS) of plasma concentrations of warfarin enantiomers/metabolites in sub-Saharan black-Africans. This overcomes the issue of non-adherence and may have greater sensitivity at genome-wide level, to identify pharmacokinetic gene variants than focusing on mean weekly dose, the usual end-point used in previous studies. Participants recruited at 12 outpatient sites in Uganda and South Africa on stable warfarin dose were genotyped using the Illumina Infinium H3Africa Consortium Array v2. Imputation was conducted using the 1,000 Genomes Project phase III reference panel. Warfarin/metabolite plasma concentrations were determined by high-performance liquid chromatography with tandem mass spectrometry. Multivariable linear regression was undertaken, with adjustment made for five non-genetic covariates and ten principal components of genetic ancestry. After quality control procedures, 548 participants and 17,268,054 SNPs were retained. CYP2C9*8, CYP2C9*9, CYP2C9*11, and the CYP2C cluster SNP rs12777823 passed the Bonferroni-adjusted replication significance threshold (p < 3.21E-04) for warfarin/metabolite ratios. In an exploratory GWAS analysis, 373 unique SNPs in 13 genes, including CYP2C9*8, passed the Bonferroni-adjusted genome-wide significance threshold (p < 3.846E-9), with 325 (87%, all located on chromosome 10) SNPs being associated with the S-warfarin/R-warfarin outcome (top SNP rs11188082, CYP2C19 intron variant, p = 1.55E-17). Approximately 69% of these SNPs were in linkage disequilibrium (r 2 > 0.8) with CYP2C9*8 (n = 216) and rs12777823 (n = 8). Using a pharmacokinetic approach, we have shown that variants other than CYP2C9*2 and CYP2C9*3 are more important in sub-Saharan black-Africans, mainly due to the allele frequencies. In exploratory work, we conducted the first warfarin pharmacokinetics-related GWAS in sub-Saharan Africans and identified novel SNPs that will require external replication and functional characterization before they can be considered for inclusion in warfarin dosing algorithms.

What quality of life domains are most important to older adults in residential care?

Quality of life is a critically important outcome measure in aged care. However, few studies have provided a detailed examination of what quality of life means to older adults living in residential care. In the current study, N = 43 older adults (67 to 99 years) living in six residential aged care facilities in four Australian states took part in semi-structured interviews. Participants had normal cognition through to mild /moderate cognitive impairment as measured by the PAS-Cog, were able to provide informed consent, and could participate in an interview conducted in English. Interviews were transcribed, and data was analyzed in NVivo using thematic analysis. Both physical and psycho-social aspects were identified as important for older adults' quality of life with six key quality of life domains identified: independence, mobility, pain management, social connections, emotional well-being, and activities. More research is needed to test these domains with a more diverse sample of older adults living in residential aged care, in particular older adults from culturally and linguistically diverse communities. Such qualitative work is essential for the development of suitable quality of life measures for this population and provides valuable information to inform improvements to care practices and service provision. Some ways in which the identified quality of life domains could be used to enhance care provision are discussed.
