Cost-effectiveness of an in-home respite care program to support informal caregivers of persons with dementia: A model-based analysis

Model-Based Economic Evaluations of Interventions for Dementia: An Updated Systematic Review and Quality Assessment

BACKGROUND

There has been an increase in model-based economic evaluations of interventions for dementia. The most recent systematic review of economic evaluations for dementia highlighted weaknesses in studies, including lack of justification for model assumptions and data inputs.

OBJECTIVE

This study aimed to update the last published systematic review of model-based economic evaluations of interventions for dementia, including Alzheimer's disease, with a focus on any methodological improvements and quality assessment of the studies.

METHODS

Systematic searches in eight databases, including PubMed, Cochrane, Embase, CINAHL, PsycINFO, EconLit, international HTA database, and the Tufts Cost-Effectiveness Analysis Registry were undertaken from February 2018 until August 2022. The quality of the included studies was assessed using the Philips checklist and the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) 2022 checklist. The findings were summarized through narrative analysis.

RESULTS

This review included 23 studies, comprising cost-utility analyses (87%), cost-benefit analyses (9%) and cost-effectiveness analyses (4%). The studies covered various interventions, including pharmacological (n = 10, 43%), non-pharmacological (n = 4, 17%), prevention (n = 4, 17%), diagnostic (n = 4, 17%) and integrated (n = 1, 4%) [diagnostics-pharmacologic] strategies. Markov transition models were commonly employed (65%), followed by decision trees (13%) and discrete-event simulation (9%). Several interventions from all categories were reported as being cost effective. The quality of reporting was suboptimal for the Methods and Results sections in almost all studies, although the majority of studies adequately addressed the decision problem, scope, and model-type selection in their economic evaluations. Regarding the quality of methodology, only a minority of studies addressed competing theories or clearly explained the rationale for model structure. Furthermore, few studies systematically identified key parameters or assessed data quality, and uncertainty was mostly addressed partially.

CONCLUSIONS

This review informs future research and resource allocation by providing insights into model-based economic evaluations for dementia interventions and highlighting areas for improvement.

WHO, WHEN, HOW: a scoping review on flexible at-home respite for informal caregivers of older adults

BACKGROUND

As the world population is aging, considerable efforts need to be put towards developing and maintaining evidenced-based care for older adults. Respite services are part of the selection of homecare offered to informal caregivers. Although current best practices around respite are rooted in person centeredness, there is no integrated synthesis of its flexible components. Such a synthesis could offer a better understanding of key characteristics of flexible respite and, as such, support its implementation and use.

METHODS

To map the literature around the characteristics of flexible at-home respite for informal caregivers of older adults, a scoping study was conducted. Qualitative data from the review was analyzed using content analysis. The characterization of flexible at-home respite was built on three dimensions: WHO, WHEN and HOW. To triangulate the scoping results, an online questionnaire was distributed to homecare providers and informal caregivers of older adults.

RESULTS

A total of 42 documents were included in the review. The questionnaire was completed by 105 participants. The results summarize the characteristics of flexible at-home respite found in the literature. Flexibility in respite can be understood through three dimensions: (1) WHO is tendering it, (2) WHEN it is tendered and (3) HOW it is tendered. Firstly, human resources (WHO) must be compatible with the homecare sector as well as being trained and qualified to offer respite to informal caregivers of older adults. Secondly, flexible respite includes considerations of time, duration, frequency, and predictability (WHEN). Lastly, flexible at-home respite exhibits approachability, appropriateness, affordability, availability, and acceptability (HOW). Overall, flexible at-home respite adjusts to the needs of the informal caregiver and care recipient in terms of WHO, WHEN, and HOW.

CONCLUSION

This review is a step towards a more precise definition of flexible at-home respite. Flexibility of homecare, in particular respite, must be considered when designing, implementing and evaluating services.

Economics and dementia: Challenges and responses

Economics and dementia are interconnected in many ways. There is, for example, accumulating evidence of the ways in which dementia impacts on the economic status of individuals and families, on health and social care system budgets, and on national economies. An individual's economic status can affect their risk of dementia and their ability to respond to it. Governments and other strategic decision-makers are aware of the (growing, indeed urgent) need to take action - whether that is prevention, treatment or care - but also very aware of the limited resources available to them and to the general population. Research evidence can potentially inform the difficult decisions that government and others need to take. We briefly summarise some economic evaluation studies in the dementia area as a basis for identifying the main challenges of moving from evidence to better policy and practice. We then discuss some possible responses (from a range of stakeholders) to these challenges, and how the STRiDE study has sought to contribute to this fast-moving field.

Experiences of workplace violence among healthcare workers in home care settings: A qualitative systematic review

AIMS

The aims of this systematic review were to obtain a comprehensive understanding of healthcare workers' experiences who were subjected to workplace violence in the home care environment and identify their specific support needs.

BACKGROUND

Workplace violence toward healthcare workers has been a prevalent and ongoing issue. With the expansion of home care services, more emphasis should be placed on maintaining a safe in-home care environment for healthcare workers. Understanding healthcare workers' experience of workplace violence is crucial for developing effective interventions.

METHODS

A systematic search was conducted in 10 databases from their inception date until January 2022. Primary qualitative studies were included. Two reviewers performed screening of studies, methodological quality assessment, and data extraction and analysis independently. The two-step approach by Sandelowski and Barroso on meta-summary and meta-synthesis was used. This qualitative systematic review was reported according to the PRISMA guidelines.

RESULTS

Eight studies were included. Three themes were identified: (1) impact of workplace violence, (2) reasons behind tolerating violence, and (3) way forward to prevent violence.

CONCLUSION

Workplace violence is common among healthcare workers in home care settings, yet the support provided to healthcare workers is inadequate. The findings suggest the need for effective interventions and policies to address this grave issue in order to improve the well-being of healthcare workers as it may indirectly affect the care quality provided to patients.

IMPLICATIONS FOR NURSING

Due to the unique nature of home care services, interventions preventing workplace violence must be tailored to the specific home care settings and needs of healthcare workers. Future research should develop and evaluate different interventions to prevent workplace violence in home care settings.

Adaptation of families of adult patients with brain tumor: Partial least squares structural equation modeling

Brain tumor patients experience physical, psychological, social, and cognitive changes. These changes are challenging for both the patients and their families. These patients and their families need to adapt together on the cancer treatment path. This study aimed to identify the factors affecting adaptation in families of adult patients with brain tumors. A quantitative, cross-sectional study of 165 families of adult patients with primary brain tumors was conducted using a self-administered questionnaire. Partial least squares structural equation modeling was used to test a hypothetical model. The results showed that family stress, family functioning, and family resources influenced on family adaptation in families of adult patients with primary brain tumors. Among these factors, family resources were identified to be the strongest factor associated with family adaptation. The results of this study may be utilized as a theoretical basis in nursing to improve the family adaptation of patients with brain tumors. Regarding nursing practices, the results suggest that nurses should provide family-centered nursing interventions and promote family resources to help brain tumor patients and their families to adapt.

Comparison of on Site versus Online Psycho Education Groups and Reducing Caregiver Burden

OBJECTIVES

The purpose of this project was to comparatively assess the benefit from the effects of the online versus onsite psychoeducative interventions on caregivers' emotional burden, including their sense of burden, anxiety, and depression.

METHODS

Seventy-one caregivers of Patients with Dementia (PwD) were divided in two groups, the online versus the onsite, and participated in the 4-month psychoeducational group intervention. Psychosocial assessment was performed using Beck Anxiety Inventory, Beck Depression Inventory and Zarit Burden Interview before and after the intervention.

RESULTS

No significant differences were found between the online and onsite groups in anxiety (p = .531), depression (p = .577) and sense of burden (p = .623) after the interventions. Both interventions showed significant reductions across emotional variables measured over the course of the treatment study and treatment interventions.

CONCLUSIONS

Both online and onsite interventions are effective at improving emotional health as they reduce the level of anxiety, depression, and sense of caregiver burden.

CLINICAL IMPLICATIONS

The use of online psychoeducative interventions is indicative for use by clinicians who work with dementia caregivers as compared to the onsite ones. Therefore, they may be assumed as having significant utility in dementia caregivers, especially when being adapted during the recent confinement measures due to the coronavirus disease pandemic (COVID-19).

Exploratory pilot study on resource allocation along the dementia continuum under constrained and unconstrained budget scenarios

Background

People with dementia and their carers have a wide range of health and social care needs which vary along the dementia continuum. The government response to events and transitions at various stages of the continuum can have a substantial impact on the lived experience of dementia and to resource allocation decision-making. Hearing what practitioners have to say about need at various points of transition along the dementia continuum is very important, especially for the resource allocation process.

Methods

The paper uses an innovative longitudinal balance of care (BoC) methodology to identify the impact of changes along the dementia care continuum for care recipients and practitioners throughout the course of the condition. Participatory workshops were held with five Health and Social Care Professionals (HSCPs) to pilot a mixed methods approach to resource allocation decision-making along the dementia continuum. In these workshops, these practitioner participants were asked to generate a set of services and supports for a person with dementia with changing and evolving needs over a five year period under two budget scenarios: no budget constraint (NBC); and a budget constraint (BC). Participants were asked to recommend services for short, post event, transition periods and for longer steady state periods.

Results

Participants were able to allocate different packages of services and supports for different stages of dementia under different budgetary conditions. The total cost for the five year period under the NBC scenario is €200,000 on average, reducing to €133,000 under the BC scenario. Under the BC (NBC) scenarios, participants spent on average 85% (90%) of their budget on community services and 15% (10%) on nursing home services.

Conclusion

The methodology used in this paper is a valuable complement to cross-sectional BoC studies through its identification of the importance of events, transitions and staging along the dementia care continuum. The desire of participants to keep people with dementia living in their own home is strong, even in the later stages of dementia, as evident by their recommendation to spend €400 per week more on home care provision compared to the alternative residential care, albeit in the absence of any budget constraints.

Resource allocation in dementia care: comparing the views of people with dementia, carers and health and social care professionals under constrained and unconstrained budget scenarios

BACKGROUND

People with dementia and their carers have a wide range of health and social care needs. People with dementia, carers and health and social care professionals (HSCPs) all have different perspectives on dementia care. Differences among these groups are important for commissioners of services and for front-line HSCPs.

OBJECTIVE

To compare the service recommendations of people with dementia and carers with those of HSCPs, under different budgetary conditions.

METHODS

A mixed-methods approach, which builds on the Balance of Care method, was used. Nine workshops were held with 41 participants from three groups: people with dementia, carers and HSCPs. Participants were asked to make decisions on a set of services for case types of dementia under two scenarios: a no budget constraint (NBC) scenario and a budget constraint (BC) scenario.

RESULTS

While each group allocated resources in broadly similar overall proportions, important differences in emphasis emerged: (i) people with dementia and carers placed more emphasis on psychosocial supports than HSCPs; (ii) carers put more emphasis on respite opportunities for carers; and (iii) carers identified residential care as the most suitable setting for the person with dementia more frequently than health care professionals.

CONCLUSION

Our findings suggest that the importance of psychosocial interventions, including counselling and peer support programmes, are currently underestimated by HSCPs. The provision of in-home respite is highly valued by carers. Even with unconstrained resources, some carers do not judge home care to be a viable option for dementia case types with high-level care needs.

Design and evaluation of a dashboard to support the comprehension of the progression of patients with dementia in day centers

BACKGROUND AND OBJECTIVE

In day centers, people with dementia are assigned to specific groups to receive care according to the progression of the disease. This article presents the design and evaluation of a dashboard aimed at facilitating the comprehension of the progression of people with dementia to support decision-making of healthcare professionals (HCPs) when determining patient-group assignment.

MATERIALS AND METHOD

A participatory design methodology was followed to build the dashboard. The grounded theory methodology was utilized to identify requirements. A total of 8 HCPs participated in the design and evaluation of a low-fidelity prototype. The perceived usefulness and perceived ease of use of the high-fidelity prototype was evaluated by 15 HCPs (from several day centers) and 38 psychology students utilizing a questionnaire based on the technology acceptance model.

RESULTS

HCPs perceived the dashboard as extremely likely to be useful (Mdn=6.5 out of 7) and quite likely to be usable (Mdn=6 out of 7). Psychology students perceived the dashboard as quite likely to be useful and usable (both with Mdn=6).

CONCLUSIONS

Making use of a participatory design helped foster in HCPs a sense of ownership of the dashboard, thus facilitating its acceptance. The creation of low-fidelity and high-fidelity prototypes led to identifying valuable, timely, and specific feedback at different stages of the development process as well as to establishing a set of lessons learned for the development of dashboards in the healthcare domain.

Which factors increase informal care hours and societal costs among caregivers of people with dementia? A systematic review of Resource Utilization in Dementia (RUD)

BACKGROUND

Nearly 19 million people across OECD countries are living with dementia, and millions of family caregivers are affected by the disease. The costs of informal care are estimated to represent 40-75% of the total dementia cost exceeding formal care time and medical costs.

OBJECTIVE

To conduct a systematic review to evaluate the methodological quality and factors associated with high informal care hours per month that increase societal costs, and to identify what type of interventions may alleviate the entire burden of informal and formal caregiving.

METHODS

The systematic review was registered at PROSPERO (15.12.2020). A search in Medline, Embase, PsycINFO, and web of science for observational studies, cost-effectiveness, and cost of illness (COI) analyses on resource utilization in dementia (RUD) was conducted on 1 December 2020. Our inclusion criteria included a requirement that studies had to use the original RUD, RUD-FOCA or RUD lite in terms of hours or days per month, and costs as primary or secondary outcome, OECD countries, within the last 20 years and a sample population comprising persons with dementia (PwD) ≥65 years and their caregivers. We followed the PRISMA, GRADE, PICO guidelines and Drummond criteria to assess the methodology and quality of the studies.

RESULTS

Of 307 studies, 26 cross-sectional and 3 longitudinal cohort studies were included in the analyses. Two studies had a randomized controlled trial (RCT) design. The methods and cost categories in each study varied widely. Disease severity, caregiver factors, and behavioural and psychological symptoms of dementia (BPSD) were associated with high informal care hours and societal cost. One RCT found no effect of a non-pharmacological intervention on informal care hours, yet another RCT found a cost-effective impact of an in-home respite care programme reducing informal care burden and costs.

CONCLUSION

The divergent use of the RUD components within included studies encourage more harmonized analyses. There are only two RCTs on RUD, one of which shows a significant treatment effect. Larger sample sizes and longer follow-up periods are required in future RCTs with dedicated focus on cost-enhancing and resource intensive factors such as disease severity and BPSD. Novel interventions must diversify between caregiver and PwD groups.

Supporting family carers of people with dementia: A discrete choice experiment of public preferences

Community-based care for people with dementia is mainly provided by family carers, many of whom experience decreased mental, physical and financial well-being due to their caring role. Many countries are now implementing ageing-in-place policies that have increased pressure on family carers as care-work is redistributed from residential to community-based settings. Family caring responsibilities for people with dementia are made even more complicated by the economic, social and cultural expectations that underpin existing provision. Support for family carers is, therefore, an important policy topic across many countries. The focus of this paper is on the propensity of citizens to support enhanced care for family carers in Ireland, as demonstrated by their willingness-to-pay additional taxation to fund different combinations of carer support measures, developed through careful and sustained dialogue with multiple stakeholders, especially family carers themselves. We carried out a discrete choice experiment (DCE) with 509 members of the general public in Ireland between January and February 2021. Using mixed logit models, our findings show that citizens value four key attributes: regular caring breaks for family carers (day-care and long-break respite); financial compensation (carer's allowance); and emotional support (carer peer support groups). We also estimated the welfare impact of moving from current provision to enhanced support packages for family carers of people with dementia. The welfare gains accumulate to €1035.80 for the most complete levels of provision across the four support attributes. Overall, respondents in this paper showed empathy and understanding towards family carers of people with dementia through their willingness to contribute to funding additional services and supports.

Cost-effectiveness of a telehealth intervention for in-home dementia care support: Findings from the FamTechCare clinical trial

Determining the cost-effectiveness of technological interventions is a crucial aspect in assuring these interventions can be adopted. The FamTechCare intervention is an innovative telehealth support that links family caregivers of persons living with dementia to tailored feedback from dementia care experts based on caregiver-initiated video recordings of challenging care situations. The FamTechCare intervention has demonstrated significant reductions in caregiver depression and increases in caregiver competence when compared to standard telephone support. The purpose of this article is to report on the cost-effectiveness of the FamTechCare telehealth intervention. Process-based costing and a cost-effectiveness analysis using the incremental cost-effectiveness ratio (ICER) was completed with 68 caregiver and person living dementia with dyads. The cost of the 12-week FamTechCare telehealth intervention was found to be greater ($48.43 per dyad per week) due to the telehealth equipment, recording application, and expert panel time compared with the telephone support intervention ($6.96 per dyad per week). The ICER was $18.51 for caregiver depression and $36.31 for caregiver competence indicating that it cost no more than $36.38 per dyad per week over 12 weeks to achieve significant improvement in depression and competence in the FamTechCare caregivers compared to the telephone support caregivers. The FamTechCare intervention appears to be cost-effective when compared to the telephone support intervention and remains near the willingness-to-pay threshold for caregivers providing in-home dementia care support.
