Cost-effectiveness of the FindMyApps eHealth intervention vs. digital care as usual: results from a randomised controlled trial

OBJECTIVES

Despite growing interest, the cost-effectiveness of eHealth interventions for supporting quality of life of people with dementia and their caregivers remains unclear. This study evaluated the cost-effectiveness of the FindMyApps intervention, compared to digital care-as-usual. FindMyApps aims to help people with dementia and their caregivers find and learn to use tablet apps that may support social participation and self-management of people with dementia and sense of competence of caregivers.

METHOD

A randomised controlled trial (Netherlands Trial Register NL8157) was conducted, including people with mild cognitive impairment (MCI) or mild dementia and their informal caregivers (FindMyApps n = 76, digital care-as-usual n = 74). Outcomes for people with MCI/dementia were Quality-Adjusted Life-Years (QALYs), calculated from EQ-5D-5L data and the Dutch tariff for utility scores, social participation (Maastricht Social Participation Profile) and quality of life (Adult Social Care Outcomes Toolkit), and for caregivers, QALYs and sense of competence (Short Sense of Competence Questionnaire). Societal costs were calculated using data collected with the RUD-lite instrument and the Dutch costing guideline. Multiple imputation was employed to fill in missing cost and effect data. Bootstrapped multilevel models were used to estimate incremental total societal costs and incremental effects between groups which were then used to calculate Incremental Cost-Effectiveness Ratios (ICERs). Cost-effectiveness acceptability curves were estimated.

RESULTS

In the FindMyApps group, caregiver SSCQ scores were significantly higher compared to care-as-usual, n = 150, mean difference = 0.75, 95% CI [0.14, 1.38]. Other outcomes did not significantly differ between groups. Total societal costs for people with dementia were not significantly different, n = 150, mean difference = €-774, 95%CI [-2.643, .,079]. Total societal costs for caregivers were significantly lower in the FindMyApps group compared to care-as-usual, n = 150, mean difference = € -392, 95% CI [-1.254, -26], largely due to lower supportive care costs, mean difference = €-252, 95% CI [-1.009, 42]. For all outcomes, the probability that FindMyApps was cost-effective at a willingness-to-pay threshold of €0 per point of improvement was 0.72 for people with dementia and 0.93 for caregivers.

CONCLUSION

FindMyApps is a cost-effective intervention for supporting caregivers' sense of competence. Further implementation of FindMyApps is warranted.

Understanding the extent to which PROMs and PREMs used with older people with severe frailty capture their multidimensional needs: A scoping review

BACKGROUND

Older people with severe frailty are nearing the end of life but their needs are often unknown and unmet. Systematic ways to capture and measure the needs of this group are required. Patient reported Outcome Measures (PROMs) & Patient reported Experience Measures (PREMs) are possible tools to assist this.

AIM

To establish whether, and in what ways, the needs of older people living with severe frailty are represented within existing PROMs and PREMs and to examine the extent to which the measures have been validated with this patient group.

DESIGN

The scoping review follows the method of Arksey and O'Malley.

RESULTS

Seventeen papers from 9 countries meeting the inclusion criteria and 18 multi-dimensional measures were identified: 17 PROMs, and 1 PROM with PREM elements. Seven out of the 18 measures had evidence of being tested for validity with those with frailty. No measure was developed specifically for a frail population. Using the adapted framework of palliative need, five measures covered all five domains of palliative need (IPOS, ICECAP-SCM, PDI, WHOQOL-BREF, WHOQOL-OLD). The coverage of items within the domains varied between the measures.

CONCLUSION

Existing PROMs and PREMs are not well designed for what we know about the needs of older people with severe frailty. Future research should firstly focus on adapting and validating the existing measures to ensure they are fit for purpose, and secondly on developing a better understanding of how measures are used to deliver/better person-centred care.

FindMyApps compared with usual tablet use to promote social health of community-dwelling people with mild dementia and their informal caregivers: a randomised controlled trial

Background

FindMyApps is a tablet-based eHealth intervention designed to help people learn to use a tablet and find easy-to-use apps. This study evaluated the effectiveness of FindMyApps for supporting social health of people living with dementia, and sense of competence of their informal caregivers.

Methods

A single-centre, two-arm, non-blinded randomised controlled trial was conducted (Netherlands Trial Register NL8157). From 1st January 2020 to 31st July 2022, community-dwelling people in the Netherlands with a pre-established diagnosis of mild cognitive impairment (MCI) or dementia (Brief Cognitive Rating Scale 17-32), an informal caregiver and internet connection were allocated by block randomisation to receive FindMyApps or digital care-as-usual. Primary outcomes (measured at baseline and after three months) for people with dementia/MCI were self-management (Adult Social Care Outcomes Toolkit total score) and social participation (Maastricht Social Participation Profile frequency and diversity scores), and for caregivers, sense of competence (Short Sense of Competence Questionnaire total score). Between-group differences were tested by MANCOVA or ANCOVA (alpha = 0.05).

Findings

150 dyads were randomised (FindMyApps n = 76, care-as-usual n = 74). Follow-up data were available for 128 dyads (FindMyApps n = 64, care-as-usual n = 64), who were included in the analysis in the trial arm to which they were assigned. No harms of the intervention were identified. There were no statistically significant differences in outcomes for people with dementia/MCI at group level. Diagnosis and experiencing apathy appeared to be relevant effect modifiers of secondary outcomes (neuropsychiatric symptoms, positive affect, sense of belonging, and pleasurable activities). Caregivers who received FindMyApps had higher sense of competence at three months (F [1,123] = 7.01, p = 0.0092, η2 = 0.054).

Interpretation

Overall we found no evidence that the FindMyApps intervention better supported social participation or self-management of people with MCI/dementia than digital care-as-usual. FindMyApps does seem to better support informal caregivers' sense of competence. For people with a diagnosis of mild dementia and older people, better tailored interventions, implementation and outcome measures may be needed.

Social care-related quality of life of people with dementia and their carers in England

People with dementia and their carers are a growing subgroup of people who use community-based social care. These services are designed to maintain people's quality of life while living at home. The ASCOT measure of social care-related quality of life (SCRQoL), designed to evaluate quality and effectiveness of social care, has been adapted for proxy-report when someone is unable to self-report. The ASCOT-Carer has been developed to measure carer's own SCRQoL. This study sought to establish the factors related to SCRQoL of people living with dementia (PLWD, proxy-reported by carers) and their carers. Data were collected via a self-administered postal or online survey of 313 carers in England, from January 2020 to April 2021. Carers were eligible if they supported someone living with dementia at home, who was unable to self-complete questionnaires. The person living with dementia or their carer had to use at least one social care service, e.g. home care. We recruited participants via an online volunteer panel and NHS sites. Multiple regression was applied to explore the factors significantly related to ASCOT SCRQoL by self- and proxy-report. Key influences on carers' own SCRQoL were their health, financial difficulties associated with caring, and satisfaction with social care support. Inadequate home design was significantly negatively associated with SCRQoL for PLWD. The latter stages of the pandemic-related restrictions (the tier system from 2nd December 2020 to study end, April 2021) were associated with significantly worse SCRQoL for PLWD, but not for carers. The study offers insight into the factors associated with SCRQoL. In particular, the findings highlight the importance of adequate home design for people with dementia; satisfactory social care support and limiting any adverse financial impact of caring are important for carers. The findings indicate a negative effect of COVID restrictions on SCRQoL of people with dementia.

Supporting the involvement of older adults with complex needs in evaluation of outcomes in long-term care at home programmes

Background

It is important to involve older people in evaluating public programmes that affect their lives. This includes those with physical and cognitive impairments (such as dementia) who may need support to live at home. Many countries have implemented new approaches to support older people to live well at home for longer. However, it can be challenging to involve disabled people in service evaluation, so we are unclear whether services are meeting their needs.

Aim

This study explored how a cascading methodology, offering different supports enabled the involvement of home care users with cognitive and physical impairments in the assessment of their care‐related quality of life.

Method

We used multiple tools from the Adult Social Care Outcomes Toolkit (ASCOT) with n = 63 older adults who were recipients of home care in the Illawarra. We also offered different physical and cognitive supports as needed.

Results

We started with the standard ASCOT questionnaire to assess the care‐related quality of life, but then offered alternative formats (including Easy Read) and supports (including physical and cognitive assistance) if the older person needed them to participate. This allowed us to involve a greater diversity of older people in the evaluation, and changed what we found out about whether their care needs were being met.

Conclusion

There is a need to implement more flexible and inclusive methods to increase the involvement of vulnerable users of long‐term care in the assessment of service outcomes. This is important to ensure that the perspectives of all service users inform the delivery of person‐centred care. It is also critical to understand the extent to which programmes are meeting the needs of vulnerable service users.

Patient or Public Contribution

Service users with dementia were involved in the design of the ‘Easy Read’ questionnaire used in the study.

The (cost-)effectiveness of an implemented fall prevention intervention on falls and fall-related injuries among community-dwelling older adults with an increased risk of falls: protocol for the in balance randomized controlled trial

Background

Falls and fall-related injuries among older adults are a serious threat to the quality of life and result in high healthcare and societal costs. Despite evidence that falls can be prevented by fall prevention programmes, practical barriers may challenge the implementation of these programmes. In this study, we will investigate the effectiveness and cost-effectiveness of In Balance, a fourteen-week, low-cost group fall prevention intervention, that is widely implemented in community-dwelling older adults with an increased fall risk in the Netherlands. Moreover, we will be the first to include cost-effectiveness for this intervention. Based on previous evidence of the In Balance intervention in pre-frail older adults, we expect this intervention to be (cost-)effective after implementation-related adjustments on the target population and duration of the intervention.

Methods

This study is a single-blinded, multicenter randomized controlled trial. The target sample will consist of 256 community-dwelling non-frail and pre-frail adults of 65 years or older with an increased risk of falls. The intervention group receives the In Balance intervention as it is currently widely implemented in Dutch healthcare, which includes an educational component and physical exercises. The physical exercises are based on Tai Chi principles and focus on balance and strength. The control group receives general written physical activity recommendations. Primary outcomes are the number of falls and fall-related injuries over 12 months follow-up. Secondary outcomes consist of physical performance measures, physical activity, confidence, health status, quality of life, process evaluation and societal costs. Mixed model analyses will be conducted for both primary and secondary outcomes and will be stratified for non-frail and pre-frail adults.

Discussion

This trial will provide insight into the clinical and societal impact of an implemented Dutch fall prevention intervention and will have major benefits for older adults, society and health insurance companies. In addition, results of this study will inform healthcare professionals and policy makers about timely and (cost-)effective prevention of falls in older adults.

Social care-related outcomes in Finland. Construct validity and structural characteristics of the Finnish ASCOT measure with older home care users

The Adult Social Care Outcomes Toolkit four response-level interview schedule (ASCOT INT4) for service users was translated into Finnish. The aim of this paper was to investigate the construct validity and structural characteristics of the Finnish ASCOT. We used data from a face-to-face interview survey of older people receiving publicly funded home care services, which was conducted in 2016-2017 (n = 493), excluding missing values and proxy respondents (n = 334). Chi-square tests, adjusted residuals and analyses of variance were used to examine hypothesised associations between each attribute and a number of relevant variables regarding health and well-being, disabilities, living arrangements, social contact and support, experience of service use, and the nature of the locality and environment. Structural characteristics were explored using exploratory factor analysis and Cronbach's alpha test. The EQ-5D-3L and ASCOT were moderately correlated (r = 0.429; p < 0.001). The ASCOT attributes were statistically positively related to the overall quality of life. For other tested variables, we found a high number of significant associations with the control over daily life, occupation, social participation, and personal cleanliness attributes, but fewer significant associations with the other attributes. Cronbach's alpha was 0.697 and a single factor was extracted. This assessment provides evidence to support the construct validity of the Finnish ASCOT. The results support the introduction of the Finnish ASCOT into Finland for use in practical applications. Future research on its reliability would be useful.

Impact of the FindMyApps program on people with mild cognitive impairment or dementia and their caregivers; an exploratory pilot randomised controlled trial

PURPOSE

FindMyApps is a web-based selection-tool and errorless learning training program to help people with mild dementia/Mild Cognitive Impairment (MCI) and caregivers find user-friendly apps. In preparation of a definitive trial, the impact and feasibility of the FindMyApps intervention on self-management and engagement in meaningful activities, including social participation, was explored.

MATERIALS AND METHODS

An exploratory pilot randomised controlled trial (trial registration approval number: NL7210) with pre/post measurements was conducted with community-dwelling people with mild dementia/MCI and their caregivers (n = 59) in the Netherlands. Dyads in the experimental group (n = 28) received training to use the tablet and FindMyApps, and the errorless learning method was taught to their caregivers. Control group dyads (n = 31) received a tablet (without FindMyApps), instructions on tablet-use and links to dementia-friendly apps. Validated instruments were used to assess person with dementia's self-management, meaningful activities and social participation, caregiver's sense of competence and both their quality of life.

RESULTS AND CONCLUSIONS

No statistical significant group differences on the outcomes were found. Small to moderate effect-sizes in favour of the FindMyApps group were found for self-management and social participation. Caregivers tended to have more positive care experiences. Subgroup analyses showed that people older than 70 benefitted more from FindMyApps regarding self-management and higher educated people benefitted more regarding social participation. FindMyApps is feasible for the target group and may have potential to improve self-management and social participation. For a future definitive effectiveness trial a larger sample size is recommended, as well as taking into account the possible impact of education and age.IMPLICATIONS FOR REHABILITATIONThe FindMyApps program is feasible for people with dementia/MCI and may have potential to improve their self-management and social participation.Informal caregivers may develop a more positive care experience when utilizing FindMyApps to find suitable apps for self-management and social participation for the person with dementia/MCI.

Testing the suitability of the ACCOM tool to measure outcomes of care for Culturally and Linguistically Diverse older people

The Australian Community Outcomes Measurement (ACCOM) uses a standardized set of instruments to measures functional, health, and social care-related quality of life (SCRQoL) among older people receiving services at home. One of its key components is the use of modified ASCOT SCT4 survey developed by The University of Kent PSSRU. This paper presents the preliminary findings of a pilot testing of ACCOM with CALD clients in South West Sydney using face to face interviews conducted by bilingual workers as a novel approach to administering the tool. The paper will argue that some of the domains in ASCOT SCT4 survey pose unique challenges for culturally diverse groups that highlight the ethnocentric nature of some of the questions. It also discusses some of the strategies the service provider used to address these concerns and be able to utilize the tool in a culturally effective manner.

Effects of Exergaming on Cognitive and Social Functioning of People with Dementia: A Randomized Controlled Trial

OBJECTIVES

Physical activity in people with dementia (PwD) may enhance physical and mental functioning. Exergaming, which combines physical exercise with cognitive stimulation in a gaming environment, was developed to overcome barriers in performing physical activities. We evaluated the effects of exergaming in day care centers (DCCs) for PwD and informal caregivers (ICs).

DESIGN

A randomized controlled trial among 23 DCCs across the Netherlands randomized to exergaming (interactive cycling during 6 months) or a care-as-usual control group.

SETTING AND PARTICIPANTS

A total of 112 (73 exergaming, 39 control) community-dwelling dyads (PwD, IC), with the PwD visiting a DCC at least twice per week.

METHODS

All outcomes were assessed using structured questionnaires during interviews with PwD and ICs at baseline (T0), 3 months (T1), and 6 months (T2). Primary outcomes: physical activity and mobility of the PwD.

SECONDARY OUTCOMES

physical, cognitive, emotional and social functioning, and quality of life for PwD. For ICs: experienced burden, quality of life, and positive care experiences.

RESULTS

Mixed-model analyses showed no statistically significant effects on primary outcomes. There were statistically significant positive effects on PwD's secondary outcomes at T2 on cognition [Mini-Mental State Examination (MMSE): r = 2.30, 95% confidence interval (CI): 0.65, 3.96, P = .007; and Trail Making Test part A (TMT-A): r = -28.98, 95% CI: -54.89, -3.08, P = .029], social functioning (Behavior Observation Scale for Intramural Psychogeriatrics subscale 1 (GIP): r = -1.86, 95% CI: -3.56, -0.17, P = .031), and positive post-test effects in ICs on distress caused by the PwD's neuropsychiatric symptoms (NPI-Q total distress: r = -3.30, 95% CI: -6.57, -0.03, P = .048) and on sense of competence (SSCQ: r = 2.78, 95% CI: 0.85, 4.71, P = .005).

CONCLUSIONS AND IMPLICATIONS

Exergaming appeared not effective on the primary outcomes. Despite the study being underpowered, we found positive effects on secondary outcomes for PwD and ICs, and no negative effects. We therefore recommend further study, dissemination, and implementation.

Capability instruments in economic evaluations of health-related interventions: a comparative review of the literature

PURPOSE

Given increasing interest in using the capability approach for health economic evaluations and a growing literature, this paper aims to synthesise current information about the characteristics of capability instruments and their application in health economic evaluations.

METHODS

A systematic literature review was conducted to assess studies that contained information on the development, psychometric properties and valuation of capability instruments, or their application in economic evaluations.

RESULTS

The review identified 98 studies and 14 instruments for inclusion. There is some evidence on the psychometric properties of most instruments. Most papers found moderate-to-high correlation between health and capability measures, ranging between 0.41 and 0.64. ASCOT, ICECAP-A, -O and -SCM instruments have published valuation sets, most frequently developed using best-worst scaling. Thirteen instruments were originally developed in English and one in Portuguese; however, some translations to other languages are available. Ten economic evaluations using capability instruments were identified. The presentation of results show a lack of consensus regarding the most appropriate way to use capability instruments in economic evaluations with discussion about capability-adjusted life years (CALYs), years of capability equivalence and the trade-off between maximisation of capability versus sufficient capability.

CONCLUSION

There has been increasing interest in applying the capability-based approach in health economic evaluations, but methodological and conceptual issues remain. There is still a need for direct comparison of the different capability instruments and for clear guidance on when and how they should be used in economic evaluations.

Population-based preference weights for the Adult Social Care Outcomes Toolkit (ASCOT) for service users for Austria: Findings from a best-worst experiment

BACKGROUND

The Adult Social Care Outcomes Toolkit (ASCOT) measures quality-of-life (QoL) outcomes of long-term care (LTC) service provision. Country-specific preference weights are required to calculate ASCOT scores. ASCOT has been translated into German, but lacks preference weights for German-speaking countries.

OBJECTIVES

This paper aims to establish Austrian preference weights for the German version of the ASCOT service user measure, using best-worst scaling (BWS).

METHODS

Data were collected using an online BWS-experiment from a general population sample (n=1,000) of Austrian adults. We use a scale-adjusted multinomial logit model (S-MNL) accounting for positioning effects to estimate preference weights.

RESULTS

Austrians value the top attribute-levels in the ASCOT domains 'being meaningfully occupied during the day' and 'having control over daily life' most highly, whereas high needs were the least preferred in the domains 'dignity' and 'social participation'. From a methods perspective, we found significant positioning effects only for 'best' choices, with statements at the top of a list being picked more often than those further down in the list. Factors related to survey completion (self-assessed understanding of the tasks and survey completion time) were shown to have the greatest effect on individual choice consistency.

DISCUSSION

The paper provides Austrian preference weights for the German version of ASCOT for service users. The weights also provide insight into how Austrians value different LTC-QoL states. Future research may investigate how values for different LTC-QoL states differ between socioeconomic groups.

From protocolized to person-centered chronic care in general practice: study protocol of an action-based research project (COPILOT)

AIM

To develop a proactive person-centered care approach for persons with (multiple) chronic diseases in general practice, and to explore the impact on 'Quadruple aims': experiences of patients and professionals, patient outcomes and costs of resources use.

BACKGROUND

The management of people with multiple chronic diseases challenges health care systems designed around single disease. Patients with multimorbidity often receive highly fragmented care that may lead to inefficient, ineffective and potentially harmful treatments and neglect of essential health needs. A more comprehensive, person-centered approach is advocated for persons with multiple morbidities. However, examples on how to provide more person-centered care and evidence of its impact are scarce. A group of Dutch general practitioners (GPs) took the initiative to develop such a care approach.

METHODS/DESIGN

Mixed methods with a development and pilot-testing phase. The proactive person-centered approach will be developed using an action-based research design consisting of multiple plan-act-observe-reflect-adjust cycles. In each cycle, experiences of patients and primary care professionals from 13 practices will be collected via interviews, observations and focus groups. Starting point for the first cycle is a 'person-centered consultation' of up to 1 h in which the GP discusses the health status and health care needs of the patient. Furthermore, shared decisions between GP and patient are made on treatment goals and follow-up. In the pilot-test phase, a nested case cohort study allows to explore the impact of the new approach on 'Quadruple aim' outcomes comparing persons with and without exposure to the new care approach.

DISCUSSION

This study will provide a proactive person-centered approach for persons with multimorbidity in primary care and estimate its potential impact on quadruple outcomes.

Development of Japanese utility weights for the Adult Social Care Outcomes Toolkit (ASCOT) SCT4

Purpose

In developed countries, progressive rapid aging is increasing the need for social care. This study aimed to determine Japanese utility weights for the Adult Social Care Outcomes Toolkit (ASCOT) four-level self-completion questionnaire (SCT4).

Methods

We recruited 1050 Japanese respondents from the general population, stratified by sex and age, from five major cities. In the best–worst scaling (BWS) phase, respondents ranked various social care-related quality of life (SCRQoL) states as “best,” “worst,” “second-best,” or “second-worst,” as per the ASCOT. Then, respondents were asked to evaluate eight different SCRQOL states by composite time-trade off (cTTO). A mixed logit model was used to analyze BWS data. The association between cTTO and latent BWS scores was used to estimate a scoring formula that would convert BWS scores to SC-QALY (social care quality-adjusted life year) scores.

Results

Japanese BWS weightings for ASCOT-SCT4 were successfully estimated and found generally consistent with the UK utility weights. However, coefficients on level 3 of “Control over daily life” and “Occupation” domains differed markedly between Japan and the UK. The worst Japanese SCRQoL state was lower than that for the UK, as Japanese cTTO results showed more negative valuations. In general, Japanese SC-QALY score (for more than 90% of health states) was lower than that for the UK.

Conclusions

We successfully obtained Japanese utility weights for ASCOT SCT4. This will contribute to the measurement and understanding of social care outcomes.

Japanese translation and cross-cultural validation of the Adult Social Care Outcomes Toolkit (ASCOT) in Japanese social service users

Background

The aim of this study was to develop and perform cross-cultural validation of a Japanese version of the Adult Social Care Outcomes Toolkit (ASCOT) four-level Self-Completion questionnaire (SCT4) instrument to measure Social-Care Related Quality of Life. It was important to develop a Japanese version of the ASCOT-SCT4 and validate it in the Japanese context, given the interest in measuring outcomes of social care services in Japan.

Methods

The original version of ASCOT-SCT4 was translated into Japanese following good practice guidelines. Additionally, comments and feedback were obtained from an independent committee engaged in managing and providing social care services to refine the flow of sentences of the newly developed translated version. The resulting version was tested for cross-cultural validation among community-dwelling adults who use social care services to confirm the factorial structure and the scale system of the Japanese version, using Structural Equation Modeling and Item Response Theory.

Results

Vigorous discussion was needed to translate the original version into Japanese especially for the items control over daily life and dignity. These two items were linguistically difficult to express in everyday language so potential participants could easily understand the intended concepts. In the cross-cultural validation, we obtained values for model fit within the acceptable range: between 0.706 and 0.550 for factor loadings, 0.923 for the Comparative Fit Index, 0.910 for the Tucker-Lewis Index, and 0.083 for the Root Mean Square Error of Approximation. This confirmed the factorial structure of the Japanese version. The IRT analysis, however, revealed that the scale system needed refinement to facilitate appropriate differentiation between each response option.

Conclusions

This study provided preliminary evidence that the Japanese version of ASCOT-SCT4 is valid. As a result, the Japanese version was finalized and approved by the instrument developer.

The (cost-) effectiveness of exergaming in people living with dementia and their informal caregivers: protocol for a randomized controlled trial

Background

Physical activity is linked to benefits such as increased physical fitness, cognition, emotional and social functioning, general health and well-being in older people. Some evidence suggests that this also applies to people living with dementia. However, it can be harder for them to perform physical activities, due to several barriers, such as issues with orientation and balance problems. A relatively new type of physical activity called exergaming may help them overcome these barriers. Exergaming is “physical exercise interactively combined with cognitive stimulation in a gaming environment”. The aim of our study is to evaluate the effectiveness and cost-effectiveness of exergaming compared to regular activities in people living with dementia, who attend day-care centres. Additionally, we want to investigate whether the exergaming activity for the person living with dementia, also (indirectly) affects the informal caregiver, as well as which facilitators and barriers to implementation of exergames for this target group exist.

Methods

A cluster Randomized Controlled Trial (RCT), with economic and process evaluations alongside will be carried out. In the Netherlands, 24 day-care centres are randomized in the experimental or control group. The study group will consist of 224 dyads (community-dwelling participants with dementia and their informal caregivers), who are interviewed at baseline, and at 3 and 6 months of follow-up. The participant with dementia has to visit the day-care centre for at least two days per week, have a diagnosis of mild to moderate dementia and have an informal caregiver present, who is willing to participate. Societal cost data will be collected during interviews, using healthcare utilization diaries, and from day-care centres. The process evaluation will only involve the experimental group, and will include an online survey, qualitative interviews and focus groups.

Discussion

This study will contribute to the evidence base that more effective exercise among people with dementia will result in positive effects on their wellbeing and quality of life. This will motivate people with dementia to be physically active. We also envision that there might be a positive effect on the burden of care experienced by their informal caregivers.

Trial registration

This trial was registered at the Netherlands Trial Register (NTR) on December 10, 2015 (number: NTR5537), this publication is based on protocol amendment number 01, issue date 28 December 2018. This includes all items from the World Health Organization Trial Registration Data Set [see Additional file 1].

Validity and test-retest reliability of the self-completion adult social care outcomes toolkit (ASCOT-SCT4) with adults with long-term physical, sensory and mental health conditions in England

BACKGROUND

The Adult Social Care Outcomes Toolkit (ASCOT-SCT4) is a multi-attribute utility index designed for the evaluation of long-term social care services. The measure comprises eight attributes that capture aspects of social care-related quality of life. The instrument has previously been validated with a sample of older adults who used home care services in England. This paper aims to demonstrate the instrument's test-retest reliability and provide evidence for its validity in a diverse sample of adults who use publicly-funded, community-based social care in England.

METHODS

A survey of 770 social care service users was conducted in England. A subsample of 100 services users participated in a follow-up interview between 7 and 21 days after baseline. Spearman rank correlation coefficients between the ASCOT-SCT4 index score and the EQ-5D-3 L, the ICECAP-A or ICECAP-O and overall quality of life were used to assess convergent validity. Data on variables hypothesised to be related to the ASCOT-SCT4 index score, as well as rating of individual attributes, were also collected. Hypothesised relationships were tested using one-way ANOVA or Fisher's exact test. Test-retest reliability was assessed using the intra-class correlation coefficient for the ASCOT-SCT4 index score at baseline and follow-up.

RESULTS

There were moderate to strong correlations between the ASCOT-SCT4 index and EQ-5D-3 L, the ICECAP-A or ICECAP-O, and overall quality of life (all correlations ≥ 0.3). The construct validity was further supported by statistically significant hypothesised relationships between the ASCOT-SCT4 index and individual characteristics in univariate and multivariate analysis. There was also further evidence for the construct validity for the revised Food and drink and Dignity items. The test-retest reliability was considered to be good (ICC = 0.783; 95% CI: 0.678-0.857).

CONCLUSIONS

The ASCOT-SCT4 index has good test-retest reliability for adults with physical or sensory disabilities who use social care services. The index score and the attributes appear to be valid for adults receiving social care for support reasons connected to underlying mental health problems, and physical or sensory disabilities. Further reliability testing with a wider sample of social care users is warranted, as is further exploration of the relationship between the ASCOT-SCT4, ICECAP-A/O and EQ-5D-3 L indices.

The acceptability and feasibility of using the Adult Social Care Outcomes Toolkit (ASCOT) to inform practice in care homes

BACKGROUND

The Adult Social Care Outcomes Toolkit (ASCOT) measures social care related quality of life (SCRQoL) and can be used to measure outcomes and demonstrate impact across different social care settings. This exploratory study built on previous work by collecting new inter-rater reliability data on the mixed-methods version of the toolkit and exploring how it might be used to inform practice in four case study homes.

METHOD

We worked with two care home providers to agree an in-depth study collecting SCRQoL data in four case-study homes. Data was collected about residents' age, ethnicity, cognitive impairment, ability to perform activities of daily living and SCRQoL in the four homes. Feedback sessions with staff and managers were held in the homes two weeks after baseline and follow-up data collected three months later. Interviews with managers explored their views of the feedback and recorded any changes that had been made because of it.

RESULTS

Participant recruitment was challenging, despite working in partnership with the homes. Resident response rates ranged from 23 to 54 % with 58 residents from four care homes taking part in the research. 53 % lacked capacity to consent. Inter-rater reliability for the ASCOT ratings of SCRQoL were good at time one (IRR = 0.72) and excellent at time two (IRR = 0.76). During the study, residents' ability to perform activities of daily living declined significantly (z = -2.67, p < .01), as did their expected needs in the absence of services (z = -2.41, p < .05). Despite these rapid declines in functionings, residents' current SCRQoL declined slightly but not significantly (Z = -1.49, p = .14). Staff responded positively to the feedback given and managers reported implementing changes in practice because of it.

CONCLUSION

This exploratory study faced many challenges in the recruitment of residents, many of whom were cognitively impaired. Nevertheless, without a mixed-methods approach many of the residents living in the care homes would have been excluded from the research altogether or had their views represented only by a representative or proxy. The value of the mixed-methods toolkit and its potential for use by providers is discussed.

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

BACKGROUND

This paper describes the methods and results of a systematic review to identify instruments used to measure quality of life outcomes in older people. The primary focus of the review was to identify instruments suitable for application with older people within economic evaluations conducted in the aged care sector.

METHODS

Online databases searched were PubMed, Medline, Scopus, and Web of Science, PsycInfo, CINAHL, Embase and Informit. Studies that met the following criteria were included: 1) study population exclusively above 65 years of age 2) measured health status, health related quality of life or quality of life outcomes more broadly through use of an instrument developed for this purpose, 3) used a generic preference based instrument or an older person specific preference based or non-preference based instrument or both, and 4) published in journals in the English language after 2000.

RESULTS

The most commonly applied generic preference based instrument in both the community and residential aged care context was the EuroQol - 5 Dimensions (EQ-5D), followed by the Adult Social Care Outcomes Toolkit (ASCOT) and the Health Utilities Index (HUI2/3). The most widely applied older person specific instrument was the ICEpop CAPability measure for Older people (ICECAP-O) in both community and residential aged care.

CONCLUSION

In the absence of an ideal instrument for incorporating into economic evaluations in the aged care sector, this review recommends the use of a generic preference based measure of health related quality of life such as the EQ-5D to obtain quality adjusted life years, in combination with an instrument that has a broader quality of life focus like the ASCOT, which was designed specifically for evaluating interventions in social care or the ICECAP-O, a capability measure for older people.
