Further Evidence of Feasibility, Validity, and Reliability of Quality of Life-Aged Care Consumers: Evidence From Home-Based Care Settings. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2024; 27:1206-1214. [PMID: 38795955 DOI: 10.1016/j.jval.2024.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 04/22/2024] [Accepted: 05/10/2024] [Indexed: 05/28/2024]
Abstract
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.

Using EQ-5D for Proxy Assessment of Health-Related Quality of Life in Residential Care Facilities: A Systematic Review of Feasibility and Psychometric Properties. J Am Med Dir Assoc 2024; 25:104870. [PMID: 38043585 DOI: 10.1016/j.jamda.2023.10.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 10/19/2023] [Accepted: 10/23/2023] [Indexed: 12/05/2023]
Abstract
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.

PReventing and Approaching Crises for frail community-dwelling patients Through Innovative Care (PRACTIC): protocol for an effectiveness cluster randomised controlled trial. Trials 2024; 25:304. [PMID: 38711048 PMCID: PMC11075302 DOI: 10.1186/s13063-024-08117-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 04/15/2024] [Indexed: 05/08/2024] Open
Abstract
BACKGROUND Demographic changes, with an increasing number and proportion of older people with multimorbidity and frailty, will put more pressure on home care services in municipalities. Frail multimorbid people receiving home care services are at high risk of developing crises, defined as critical challenges and symptoms, which demand immediate and new actions. The crises often result in adverse events, coercive measures, and acute institutionalisation. There is a lack of evidence-based interventions to prevent and resolve crises in community settings. METHODS This is a participatory action research design (PAR) in a 6-month cluster randomised controlled trial (RCT). The trial will be conducted in 30 municipalities, including 150 frail community-dwelling participants receiving home care services judged by the services to be at risk of developing crisis. Each municipality (cluster) will be randomised to receive either the locally adapted TIME intervention (the intervention group) or care as usual (the control group). The Targeted Interdisciplinary Model for Evaluation and Treatment of Neuropsychiatric Symptoms (TIME) is a manual-based, multicomponent programme that includes a rigorous assessment of the crisis, one or more interdisciplinary case conferences, and the testing and evaluation of customised treatment measures. PAR in combination with an RCT will enhance adaptations of the intervention to the local context and needs. The primary outcome is as follows: difference in change between the intervention and control groups in individual goal achievement to resolve or reduce the challenges of the crises between baseline and 3 months using the PRACTIC Goal Setting Interview (PGSI). Among the secondary outcomes are the difference in change in the PGSI scale at 6 months and in neuropsychiatric symptoms (NPSs), quality of life, distress perceived by professional carers and next of kin, and institutionalisation at 3 and 6 months. DISCUSSION Through customised interventions that involve patients, the next of kin, the social context, and health care services, crises may be prevented and resolved. The PReventing and Approaching Crises for frail community-dwelling patients Through Innovative Care (PRACTIC) study will enhance innovation for health professionals, management, and users in the development of new knowledge and a new adapted approach towards crises.

Abstract
OBJECTIVE This study aims to examine the effects of the individually tailored complex intervention Participation Enabling Care in Nursing (PECAN) on activities and participation of residents with joint contractures. DESIGN Multicentre pragmatic cluster-randomised controlled trial. SETTING 35 nursing homes in Germany (August 2018-February 2020). PARTICIPANTS 562 nursing home residents aged ≥65 years with ≥1 major joint contracture (303 intervention group, 259 control group). INTERVENTIONS Nursing homes were randomised to PECAN (18 clusters) or optimised standard care (17 clusters) with researcher-concealed cluster allocation by facsimile. The intervention targeted impairments in activities and participation. Implementation included training and support for selected staff. Control group clusters received brief information. PRIMARY AND SECONDARY OUTCOME MEASURES The primary endpoint PaArticular Scales combined residents' activities and participation at 12 months. The secondary outcome comprised quality of life. Safety measures were falls, fall-related consequences and physical restraints. Residents, staff and researchers were unblinded. Data collection, data entry and statistical analysis were blinded. Primary analyses were intention-to-treat at cluster level and individual level using a generalised mixed-effect regression model and imputation of missing data. RESULTS Primary outcome analyses included 301 intervention group residents and 259 control group residents. The mean change on the Activities Scale was -1.47 points (SD 12.2) in the intervention group and 0.196 points (SD 12.5) in the control group and -3.87 points (SD 19.7) vs -3.18 points (SD 20.8) on the Participation Scale. The mean differences of changes between the groups were not statistically significant: Activities Scale: -1.72 (97.5% CI -6.05 to 2.61); Participation Scale: -1.24 (97.5% CI -7.02 to 4.45). We found no significant difference in the secondary outcome and no effects on safety measures. CONCLUSION The complex intervention did not improve the activities and participation of nursing home residents on the PaArticular Scales at 12 months. Current nursing conditions in Germany may hamper implementation. TRIAL REGISTRATION NUMBER DRKS00015185.

Abstract
Nursing home residents' well-being is often proxy-rated in studies, and few studies have explored the association between resident-rated person-centered climate, garden greenery, and resident-rated well-being. A cross-sectional study was conducted. Questionnaire data from a convenient sample of 470 nursing home residents in a city in Southeast China in 2021 were analyzed using multiple linear regressions, with block-wise models. The instruments used were the Person-centered Climate Questionnaire-Patient version, the Nursing Home Greenery Index, and, for well-being, the EuroQol-Visual Analogue Scale, the Life Satisfaction Questionnaire, and the 9-item Patient Health Questionnaire (depression symptoms). In the unadjusted models, the person-centered climate was positively associated with general health (β 0.29, p < 0.001), person-centered climate and greenery with life satisfaction (β 0.39, and 0.18; both p < 0.001), and negatively with depression (β -0.28, and β -0.23, both p < 0.001). After adjusting for personal and nursing home characteristics, the associations between person-centered climate, greenery, and well-being remained statistically significant. The three models explained 36%, 35%, and 21% of the variance in general health, life satisfaction, and depression, respectively. This study provides knowledge on person-centered climate in long-term care and the access to greenery.

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. Health Qual Life Outcomes 2022; 20:159. [PMID: 36456953 PMCID: PMC9713096 DOI: 10.1186/s12955-022-02065-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 10/31/2022] [Indexed: 12/03/2022] Open
Abstract
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.

Abstract
BACKGROUND EQ-5D is widely used for valuing changes in quality of life for economic evaluation of interventions for people with dementia. There are concerns about EQ-5D-3L in terms of content validity, poor inter-rater agreement and reliability in the presence of cognitive impairment, but there is also evidence to support its use with this population. An evidence gap remains regarding the psychometric properties of EQ-5D-5L. OBJECTIVES To report psychometric evidence around EQ-5D-5L in people with dementia. METHODS A systematic review identified primary studies reporting psychometric properties of EQ-5D-5L in people with dementia. Searches were completed up to November 2020. Study selection, data extraction and quality assessment were undertaken independently by at least 2 researchers. RESULTS Evidence was extracted from 20 articles from 14 unique studies covering a range of dementia severity. Evidence of known group validity from 5 of 7 studies indicated that EQ-5D-5L distinguishes severity of disease measured by cognitive impairment, depression, level of dependence and pain. Convergent validity (9 studies) showed statistically significant correlations of weak and moderate strengths, between EQ-5D-5L scores and scores on other key measures. Statistically significant change was observed in only one of 6 papers that allowed this property to be examined. All seven studies showed a lack of inter-rater reliability between self and proxy reports with the former reporting higher EQ-5D-5L scores than those provided by proxies. Five of ten studies found EQ-5D-5L to be acceptable, assessed by whether the measure could be completed by the PwD and/or by the amount of missing data. As dementia severity increased, the feasibility of self-completing EQ-5D-5L decreased. Three papers reported on ceiling effects, two found some evidence in support of ceiling effects, and one did not. CONCLUSIONS EQ-5D-5L seems to capture the health of people with dementia on the basis of known-group validity and convergent validity, but evidence is inconclusive regarding the responsiveness of EQ-5D-5L. As disease progresses, the ability to self-complete EQ-5D-5L is diminished.
