Abstract: 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 in iduals 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. 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. 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. 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.

Abstract: 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. 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. 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. Older adults may bring a different understanding to the EQ-5D-5L descriptive system than that expected given testing with general population s les. Dimension descriptors that are more relevant to this population may facilitate responses that better align with the underlying EQ-5D-5L concept model.

Abstract: To explore the perceptions of the Australian public regarding Australia's aged care workforce, including their willingness to pay more tax to fund better pay and conditions for aged care workers. An online survey was developed and administered to a representative s le of Australian adults (aged ≥18 years) by age group, gender and Australian state. Survey respondents completed a series of attitudinal statements to elicit their perceptions of the value of Australia's aged care workforce and were asked to indicate their willingness to pay additional tax to fund better pay and conditions for aged care workers. Those who gave a positive response were then asked to indicate what percentage of additional tax per year they would be willing to pay to ensure better pay and conditions for aged care workers. A total of 2033 adult respondents completed the survey. A majority (78%) of respondents either ‘agreed’ or ‘strongly agreed’ that aged care workers should be paid more. Approximately half of the respondents (50.57%) expressed a willingness to pay more tax to ensure better pay and conditions for aged care workers. The mean willingness to pay was 1.31% additional tax overall, and mean percentage additional tax values were relatively consistent across key socio‐demographic indicators. A majority of the Australian public are in favour of improving the wages and employment conditions of aged care workers. However, only one in two Australians is willing to pay more tax to ensure better pay and conditions for aged care workers.

Abstract: The recent Royal Commission into Aged Care Quality and Safety in Australia has documented systemic failures and shocking incidences of abuse and neglect, a not uncommon story internationally. As aged care in many countries is predominantly publicly funded, it is important to understand the general public's attitudes towards aged care quality, what aspects of care quality they think are most important and their willingness to contribute to increased funding to the sector. This paper asks specifically whether self-reported aged care literacy impacts expectations and willingness to pay. More than 10,000 members of the general population were surveyed stratified by age, gender and state. Regardless of the level of aged care literacy, there was consensus about what constitutes quality care, and care priorities for the sector. However, aged care literacy affected willingness to pay to fund a better-quality aged care system. The current crisis facing Australia's aged care system and that of many other countries internationally demonstrates the central importance of general public support to drive quality improvements, recognising that increasing public expenditure on aged care is a necessary part of the solution. This study provides important baseline data from which to commence national and international conversations to consider all options for ensuring the quality, safety and sustainability of aged care now and into the future.

Abstract: Quality of life (QoL) is an important outcome in aged care, but self-report is not always possible due to the high prevalence of cognitive impairment in older aged care residents. This study aims to assess the impact of family member proxy perspective (proxy-proxy or proxy-person) on interrater agreement with resident self-report by different cognition levels. The influence of proxy perspective and cognition level is a significant gap in the extant literature which this study seeks to address. A cross-sectional study was undertaken with residents classified into cognition subgroups according to the Mini Mental State Examination. Residents completed the self-report EQ-5D-5L, a well-established generic measure of health-related quality of life (HRQoL). Family member proxies completed EQ-5D-5L proxy version 1 (proxy-proxy perspective, where the proxy responds based on their own opinions) and proxy version 2 (proxy-person perspective, where the proxy responds as they believe the person would). Interrater agreement was assessed using the concordance correlation coefficient (CCC) for utility scores and the weighted kappa for dimension-level responses. Sixty-three residents (n = 22 no cognitive impairment, n = 27 mild impairment, and n = 14 moderate impairment) and proxies participated. EQ-5D-5L utility scores were lower for proxies compared with residents (self-report = 0.522, proxy-proxy = 0.299, and proxy-person = 0.408). Interrater agreement with self-report was higher for proxy-person (CCC = 0.691) than for proxy-proxy (CCC = 0.609). Agreement at the dimension level was higher for more easily observable dimensions, such as mobility, compared to less observable dimensions, such as anxiety/depression. Resident self-reported and proxy family member-reported HRQoL assessments, using the EQ-5D-5L, are different but may be more closely aligned when the proxy is specifically guided to respond from the person’s perspective. Further research is needed to address the impact of ergences in self-report and proxy-report ratings of HRQoL for quality assessment and economic evaluation in aged care.

Abstract: In economic evaluation, the quality of life of people with a disability has traditionally been assessed using preference-based instruments designed to measure and value quality of life. To provide robust measurement of the effectiveness of programs designed to improve the quality of life of people living with a disability, preference-based measures need to be sufficiently sensitive to detect incremental changes in the quality of life dimensions that are most important to people who have a disability. This study sought to explore whether there was a difference in the ranked order of importance of quality of life dimensions between people with a disability and people without a disability. An online survey was developed and administered Australia wide. The first s le (n = 410) comprised adults (aged ≥ 18 years) with a disability (n = 208) and family carers of person/s with a disability who were asked to respond on behalf of the person with a disability (n = 202). The second s le included adults without disability (n = 443). Respondents were asked to rank the importance of 12 quality of life dimensions extracted from the content of established preference-based quality of life measures (EQ-5D, AQoL and ASCOT). People with a disability placed relatively higher importance on broader quality of life dimensions (e.g. Control, Independence, Self-care ) relative to health status focused dimensions (e.g. Vision, Hearing, Physical mobility ). This distinction was less differentiable for those ‘without a disability’. The biggest differences in ranked importance of dimensions were in: Vision (‘with disability’ = 10th, ‘without disability’ = 4th), Self-care (‘with disability’ = 3rd, ‘without disability’ = 7th) and Mental well-being (‘with disability’ = 6th, ‘without disability’ = 2nd). The relative importance of quality of life dimensions for people with a disability differs to people without a disability. Quality of life is a key outcome for economic evaluation and for assessing the impact of disability care policy and practice in Australia and internationally. It is important that the effectiveness of interventions is measured and valued in ways which are fully reflective of the quality of life preferences of people with a disability.
