Costs and Burden Associated With Loss of Labor Productivity in Informal Caregivers of People With Dementia: Results From Spain

Caregivers' Absenteeism and Its Association With Health Shocks and Functional Impairment Among Persons With Severe Dementia

Adult child caregivers of persons with severe dementia (PWSDs) experience absenteeism due to caregiving. We quantified employed adult child caregivers' absenteeism; its association with PWSDs' functional impairment and health shocks; and characteristics of caregivers not experiencing absenteeism in the presence of PWSDs' health shocks and high functional impairment. We used a prospective cohort of 111 employed adult child caregivers of community-dwelling PWSDs in Singapore surveyed every 4 months for 1 year. We calculated absenteeism days due to caregiving and the corresponding absenteeism cost. Findings showed that 43% of the caregivers experienced absenteeism due to caregiving at least once during 1 year. On average, in a month, caregivers experienced 2.3 (SD = 5.9) absenteeism days and S$758 (SD = 2120) absenteeism cost. Those caring for PWSDs with high functional impairment experienced an additional 2.5 absenteeism days and S$788 absenteeism cost versus caregivers of PWSDs with low functional impairment. Caregivers whose PWSDs experienced a health shock experienced an additional 1.8 absenteeism days and S$772 absenteeism cost versus caregivers of PWSDs without a health shock. Co-residence with PWSDs worsened the impact of PSWDs' high functional impairment on caregivers absenteeism. Caregivers not co-residing with PWSDs and not using a maladaptive coping style were less likely to experience absenteeism when caring for PWSDs with a health shock. Results suggest a need to support caregivers of PWSDs to better cope with their caregiving in order to mitigate caregivers' absenteeism.

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.

The Costs of Dementia in Europe: An Updated Review and Meta-analysis

BACKGROUND AND OBJECTIVE

The prevalence of dementia is increasing, while new opportunities for diagnosing, treating and possibly preventing Alzheimer's disease and other dementia disorders are placing focus on the need for accurate estimates of costs in dementia. Considerable methodological heterogeneity creates challenges for synthesising the existing literature. This study aimed to estimate the costs for persons with dementia in Europe, disaggregated into cost components and informative patient subgroups.

METHODS

We conducted an updated literature review searching PubMed, Embase and Web of Science for studies published from 2008 to July 2021 reporting empirically based cost estimates for persons with dementia in European countries. We excluded highly selective or otherwise biased reports, and used a random-effects meta-analysis to produce estimates of mean costs of care across five European regions.

RESULTS

Based on 113 studies from 17 European countries, the estimated mean costs for all patients by region were highest in the British Isles (73,712 EUR), followed by the Nordics (43,767 EUR), Southern (35,866 EUR), Western (38,249 EUR), and Eastern Europe and Baltics (7938 EUR). Costs increased with disease severity, and the distribution of costs over informal and formal care followed a North-South gradient with Southern Europe being most reliant on informal care.

CONCLUSIONS

To our knowledge, this study represents the most extensive meta-analysis of the cost for persons with dementia in Europe to date. Though there is considerable heterogeneity across studies, much of this is explained by identifiable factors. Further standardisation of methodology for capturing resource utilisation data may further improve comparability of future studies. The cost estimates presented here may be of value for cost-of-illness studies and economic evaluations of novel diagnostic technologies and therapies for Alzheimer's disease.

A 14-Year Longitudinal Analysis of Healthcare Expenditure on Dementia and Related Factors (DEMENCOST Study)

BACKGROUND

The large number of dementia cases produces a great pressure on health and social care services, which requires efficient planning to meet the needs of patients through infrastructure, equipment, and financial, technical, and personal resources adjusted to their demands. Dementia analysis requires studies with a very precise patient characterization of both the disease and comorbidities present, and long-term follow-up of patients in clinical aspects and patterns of resource utilization and costs generated.

OBJECTIVE

To describe and quantify direct healthcare expenditure and its evolution from three years before and up to ten years after the diagnosis of dementia, compared to a matched group without dementia.

METHODS

Retrospective cohort design with follow-up from 6 to 14 years. We studied 996 people with dementia (PwD) and 2,998 controls matched for age, sex, and comorbidity. This paper adopts the provider's perspective as the perspective of analysis and refers to the costs actually incurred in providing the services. Aggregate costs and components per patient per year were calculated and modelled.

RESULTS

Total health expenditure increases in PwD from the year of diagnosis and in each of the following 7 years, but not thereafter. Health status and mortality are factors explaining the evolution of direct costs. Dementia alone is not a statistically significant factor in explaining differences between groups.

CONCLUSION

The incremental direct cost of dementia may not be as high or as long as studies with relatively short follow-up suggest. Dementia would have an impact on increasing disease burden and mortality.

A Canadian national survey of informal employed caregivers of older adults with and without dementia: Work and employee outcomes

BACKGROUND

The majority of family caregivers (CG) caring for older adults, many of whom have dementia, are employees concurrently contending with the work demands and the stress and conflicts of caregiving. Both employers and CG employees are challenged by the need to address this problem.

METHOD

A cross-sectional Canadian survey was distributed nationally to working informal CGs of older adults in 2015 to 2016. It was designed to investigate the relative predictive roles of caregiving variables, job demands, balancing work and caregiving variables, and work-related factors on work and employee outcomes. Our sample was comprised of employees (N = 1,839) who were concurrently providing informal care for an older adult with specific attention to those caring for care recipients (CR) with dementia. We employed hierarchical and ordinal multiple regression to examine CG and caregiving characteristics, family and job demands, and balancing job-caregiving variables as predictors of work-related outcomes including work engagement, employment/employee changes index, absenteeism, and intent-to-turnover.

RESULTS

After controlling for CGs' age, sex, and family financial situation, we found dementia demands, job-caregiving conflict, effective manager, and organizational culture were significant predictors of five out of six work and employee outcomes. Role overload was significantly associated with four outcomes.

CONCLUSION

To our knowledge, this is the first study of this size to explore the association of these predictive variables with work-related outcomes and to refine the understanding of the profile of employed CGs of older adults with dementia. Sustaining working CGs of older adults may require new 'talent management' approaches rather than simply increasing the number of benefits.

Amyloid-Related Imaging Abnormalities and β-Amyloid-Targeting Antibodies: A Systematic Review

Importance

After more than a decade of research and development of clinical trials testing anti-β-amyloid monoclonal antibodies (mAbs), extensive experience has been gained regarding the effects of these treatments in patients with Alzheimer disease (AD). On the verge of an expected large-scale introduction in the clinical setting after the recent US Food and Drug Administration approval of aducanumab, shared knowledge regarding amyloid-related imaging abnormalities (ARIAs) is of paramount importance.

Objective

To summarize available evidence on ARIAs from randomized clinical trials (RCTs) testing anti-β-amyloid mAbs in patients with AD and to provide a comprehensive update about risk factors, clinical correlates, and implications for withholding and reinitiating treatment.

Evidence Review

In this systematic review, a literature search of MEDLINE/PubMed, Embase, and Cochrane Library and a search of ClinicalTrials.gov were conducted through September 15, 2021. Publications describing RCTs, secondary analyses of RCT data, and case reports of ARIAs were included. Strengths of clinical data were graded according to the Oxford Centre for Evidence-Based Medicine.

Findings

Twenty-two RCTs, 11 secondary analyses of RCTs, and 1 case report, including in total 15 508 adult patients (8483 women [54.7%]; mean [SD] age, 69.6 [8.3] years) were selected for inclusion. Signal alterations that included parenchymal edema and sulcal effusion leading to transient hyperintensities on fluid-attenuated inversion recovery and T2-weighted sequences were termed ARIA-E, whereas those consisting of hemosiderin deposits, including parenchymal microhemorrhages and leptomeningeal superficial siderosis, were termed ARIA-H. Apolipoprotein E (ApoE) ε4 genotype was the main risk factor for both ARIA types; ARIA-E incidence was further associated with treatment dose, affecting the 55% of ApoE ε4 carriers in the high-dose aducanumab treatment group. Both ARIA types manifested early during study course, and symptomatic cases accounted for the 6.1% to 39.3% of ARIA-E cases at higher treatment doses across RCTs, whereas ARIA-H cases were generally asymptomatic. Most ARIA-E cases resolved with treatment withholding, although corticosteroid administration was required anecdotally. ARIA-E recurrence after dose reinitiation or adjustment varied from 13.8% to 25.6% across RCTs.

Conclusions and Relevance

Evidence suggests that ARIAs are frequent, mostly asymptomatic collateral events of amyloid-modifying therapies, highlighting the need for standardized clinical and neuroradiological management protocols in real-world clinical settings.

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.

Caregiver Characteristics and Outcomes Associated With Level of Care Complexity for Older Adults

Care in the home is increasingly complex, with family caregivers now expected to take on aspects of care previously managed by nurses and other health professionals. In a national sample of caregivers of older adults, we examined predictors and outcomes of level of care (low, medium, high) based on caregiving hours and counts of activities of daily living (ADLs) and instrumental ADLs supported. Characteristics associated with high level of care include Hispanic or "other" race/ethnicity, being unemployed, and specific care recipient conditions (e.g., Alzheimer's disease/dementia, cancer, mobility limitations). High compared to low level of care is also associated with caregiving difficulty and unmet needs. These findings underscore the need for targeted interventions and nursing research to further understand the features and dynamics of care complexity. Such research can inform family-centered interventions, health care system redesign, and health policies to support family caregivers of older adults engaged in complex care.

Development and Validation of a Prediction Model for 6-Month Societal Costs in Older Community Care-Recipients in Multiple Countries; the IBenC Study

This study aims to develop and validate a prediction model of societal costs during a period of 6-months in older community care-recipients across multiple European countries. Participants were older community care-recipients from 5 European countries. The outcome measure was mean 6-months total societal costs of resource utilisation (healthcare and informal care). Potential predictors included sociodemographic characteristics, functional limitations, clinical conditions, and diseases/disorders. The model was developed by performing Linear Mixed Models with a random intercept for the effect of country and validated by an internal-external validation procedure. Living alone, caregiver distress, (I)ADL impairment, required level of care support, health instability, presence of pain, behavioural problems, urinary incontinence and multimorbidity significantly predicted societal costs during 6 months. The model explained 32% of the variation within societal costs and showed good calibration in Iceland, Finland and Germany. Minor model adaptations improved model performance in The Netherland and Italy. The results can provide a valuable orientation for policymakers to better understand cost development among older community care-recipients. Despite substantial differences of countries’ care systems, a validated cross-national set of key predictors could be identified.

Associations between informal care costs, care quality, carer rewards, burden and subsequent grief: the international, access, rights and empowerment mortality follow-back study of the last 3 months of life (IARE I study)

BACKGROUND

At the end of life, formal care costs are high. Informal care (IC) costs, and their effects on outcomes, are not known. This study aimed to determine the IC costs for older adults in the last 3 months of life, and their relationships with outcomes, adjusting for care quality.

METHODS

Mortality follow-back postal survey.

SETTING

Palliative care services in England (London), Ireland (Dublin) and the USA (New York, San Francisco).

PARTICIPANTS

Informal carers (ICrs) of decedents who had received palliative care.

DATA

ICrs reported hours and activities, care quality, positive aspects and burdens of caregiving, and completed the Texas Revised Inventory of Grief (TRIG).

ANALYSIS

All costs (formal, informal) were calculated by multiplying reported hours of activities by country-specific costs for that activity. IC costs used country-specific shadow prices, e.g. average hourly wages and unit costs for nursing care. Multivariable logistic regression analysis explored the association of potential explanatory variables, including IC costs and care quality, on three outcomes: positive aspects and burdens of caregiving, and subsequent grief.

RESULTS

We received 767 completed surveys, 245 from London, 282 Dublin, 131 New York and 109 San Francisco. Most respondents were women (70%); average age was 60 years. On average, patients received 66-76 h per week from ICrs for 'being on call', 52-55 h for ICrs being with them, 19-21 h for personal care, 17-21 h for household tasks, 15-18 h for medical procedures and 7-10 h for appointments. Mean (SD) IC costs were as follows: USA $32,468 (28,578), England $36,170 (31,104) and Ireland $43,760 (36,930). IC costs accounted for 58% of total (formal plus informal) costs. Higher IC costs were associated with less grief and more positive perspectives of caregiving. Poor home care was associated with greater caregiver burden.

CONCLUSIONS

Costs to informal carers are larger than those to formal care services for people in the last three months of life. If well supported ICrs can play a role in providing care, and this can be done without detriment to them, providing that they are helped. Improving community palliative care and informal carer support should be a focus for future investment.

Psychoeducational intervention on burden and emotional well-being addressed to informal caregivers of people with dementia

BACKGROUND

In dementia it is necessary that a family member become an informal caregiver. This labour has social, physical and emotional repercussions on the caregiver's health. The objective was to assesses the impact of the INFOSA-DEM intervention on burden and emotional well-being among caregivers of people with dementia, evaluating the effects at 3 and 6 months.

METHOD

We adopted an experimental, non-randomised design with an intervention group and a control group. The intervention group received the intervention and the control group received usual care. The study was carried out in the catchment areas of three centres specialising in the care of people with cognitive impairment in the province of Barcelona.

RESULTS

At 3 months, there was an improvement with respect to burden in the intervention group with a significant worsening (P < 0.012) in the control group. Similarly, a positive effect on emotional well-being was observed in the intervention group compared with a small negative effect among controls.

CONCLUSIONS

Programs addressed to informal caregivers based on psychoeducational and cognitive-behavioural therapies are effective in improving quality of life and emotional well-being, and in reducing burden, with a positive effect on the quality of care provided at home.

Resultados

Todos los CNP presentaban sobrecarga basal (59,93 ± 14,71); el 73,3% manifestaban DL, con un nivel medio de 5,13 ± 2,56 e incapacidad moderada (41,7%). El 50% percibían escaso apoyo social y gran afectación de la CVRS, sobre todo en términos de dolor y ansiedad. Tras la intervención se encontró una mejora significativa (p = 0,004) en el apoyo social, así como cambios positivos de carácter descriptivo en la incapacidad por DL y dimensiones de la CVRS. No se hallaron progresos (p > 0,05) para la presencia y en el nivel de DL, así como en los niveles de sobrecarga.

Conclusiones

La intervención resulta efectiva para mejorar el apoyo social percibido. Sin embargo, el escaso impacto sobre otras variables aconseja reconsiderar sus contenidos, así como animar a nuevos estudios prospectivos que puedan ofrecer resultados más alentadores.

Family caregiving in dementia and its impact on quality of life and economic burden in Japan-web based survey

Background: Dementia has become a growing health-care problem in the rapidly ageing Japanese population. This study assesses the impact of dementia on quality of life, economic burden, and productivity loss. Objective: The objective of this study was to assess the impact of dementia on the Quality of Life (QoL), economic burden, and productivity loss among families living with dementia. Methods: An online survey was conducted among families who lived with relatives with dementia. Demographic data and information about health condition and costs of long-term care and treatment were collected. Participants were asked to answer the EuroQol (EQ-5D-5L) questionnaire, Zarit Burden Interview (ZARIT-8), and Work Productivity and Activity Impairment Questionnaire (WPAI). Multivariate analyses were conducted to assess factors associated with burden by families living with dementia. Results: Six hundred and thirty-five participants completed the survey. Of these participants, 50.5% were primary caregivers. Overall, 78.7% of dementia patients suffered from Alzheimer, and 43.9% needed long-term care. Compared to non-primary caregivers, primary caregivers had lower health utility scores (0.896 vs 0.873; p = 0.02), higher burden of caregiving (ZARIT-8: 21.1 vs 24.5; p < 0.0001), and higher overall work impairment (40.2% vs 20.8%; p < 0.0001), absenteeism (15.3% vs 5.7%; p < 0.0001), and presenteeism-related impairment (33.2% vs 17.3%; p < 0.0001). Conclusion: Families living with dementia caring for a person with dementia experience increased burden. Health policies related to dementia need to be considered not only for patients, but also for their families living with dementia to improve their QoL.

Dementia care-giving and employment: a mixed-studies review on a presumed conflict

Many persons with dementia live at home and are cared for by their relatives. If the relatives are still employed, this can lead to higher burden and losses in their work-life. The interplay between informal care-giving and working is complex. Different studies have explored this issue, but the results have not been yet synthesised. In this mixed-studies review, we elucidate the underlying complexity. Our objective is to identify the factors related to care-giving that influence employment, and to describe their impact on dementia care-givers’ employment. We performed a literature search of primary studies using four databases and one meta-database, and retrieved English- and German-language articles. We used the Mixed Methods Appraisal Tool to assess their methodological quality. Evidence identified was synthesised by a parallel-results convergent synthesis design. We included 55 qualitative, quantitative and mixed-method studies published up to January 2018. The emerging model identified factors linked to the care recipient with dementia, the informal care-giver and the care-giving context. The impacts of these factors on care-givers’ employment are mostly negative (e.g. stopped/reduced work, decreased job performance). Nevertheless, the results provide encouraging insights as working can counterbalance care-giving strain, and managing both roles can enhance care-givers’ wellbeing. Practical efforts should focus on enabling informal care-givers to better manage the balance between care-giving and work responsibilities.
