Health-care use and cost in dementia caregivers: Longitudinal results from the Predictors Caregiver Study

Promoting Successful Cognitive Aging: A Ten-Year Update

A decade has passed since we published a comprehensive review in this journal addressing the topic of promoting successful cognitive aging, making this a good time to take stock of the field. Because there have been limited large-scale, randomized controlled trials, especially following individuals from middle age to late life, some experts have questioned whether recommendations can be legitimately offered about reducing the risk of cognitive decline and dementia. Despite uncertainties, clinicians often need to at least make provisional recommendations to patients based on the highest quality data available. Converging lines of evidence from epidemiological/cohort studies, animal/basic science studies, human proof-of-concept studies, and human intervention studies can provide guidance, highlighting strategies for enhancing cognitive reserve and preventing loss of cognitive capacity. Many of the suggestions made in 2010 have been supported by additional research. Importantly, there is a growing consensus among major health organizations about recommendations to mitigate cognitive decline and promote healthy cognitive aging. Regular physical activity and treatment of cardiovascular risk factors have been supported by all of these organizations. Most organizations have also embraced cognitively stimulating activities, a heart-healthy diet, smoking cessation, and countering metabolic syndrome. Other behaviors like regular social engagement, limiting alcohol use, stress management, getting adequate sleep, avoiding anticholinergic medications, addressing sensory deficits, and protecting the brain against physical and toxic damage also have been endorsed, although less consistently. In this update, we review the evidence for each of these recommendations and offer practical advice about behavior-change techniques to help patients adopt brain-healthy behaviors.

Economic Burden of Alzheimer's Disease Dementia in Japan

BACKGROUND

Alzheimer's disease dementia (ADD) is the leading cause of long-term care in Japan.

OBJECTIVE

This study estimates the annual healthcare and long-term care costs in fiscal year 2018 for adults over 65 years of age with ADD in Japan and the informal care costs and productivity loss for their families.

METHODS

Healthcare and long-term care costs for ADD were estimated according to the disease severity classified by the clinical dementia rating (CDR) score, using reports from a literature review. For the costs of time spent on caregiving activities, productivity loss for ADD family caregivers aged 20-69 and informal care costs for all ADD family caregivers were estimated.

RESULTS

The total healthcare cost of ADD was JPY 1,073 billion, of which 86% (JPY 923 billion) was attributed to healthcare costs other than ADD drug costs (JPY 151 billion). The healthcare costs other than ADD drug costs by severity were less than JPY 200 billion for CDR 0.5, CDR 1, and CDR 2, respectively, but increased to JPY 447 billion (48%) for CDR 3. The public long-term care costs were estimated to be JPY 4,783 billion, which increased according to the severity. Total productivity loss for ADD family caregivers aged 20-69 was JPY 1,547 billion and the informal care cost for all ADD family caregivers was JPY 6,772 billion.

CONCLUSION

ADD costs have a significant impact on public-funded healthcare, long-term care systems, and families in Japan. To minimize the economic burden of ADD, prolonging healthy life expectancy is the key factor to address.

Tip of the Iceberg: Assessing the Global Socioeconomic Costs of Alzheimer's Disease and Related Dementias and Strategic Implications for Stakeholders

While it is generally understood that Alzheimer’s disease (AD) and related dementias (ADRD) is one of the costliest diseases to society, there is widespread concern that researchers and policymakers are not comprehensively capturing and describing the full scope and magnitude of the socioeconomic burden of ADRD. This review aimed to 1) catalogue the different types of AD-related socioeconomic costs described in the literature; 2) assess the challenges and gaps of existing approaches to measuring these costs; and 3) analyze and discuss the implications for stakeholders including policymakers, healthcare systems, associations, advocacy groups, clinicians, and researchers looking to improve the ability to generate reliable data that can guide evidence-based decision making. A centrally emergent theme from this review is that it is challenging to gauge the true value of policies, programs, or interventions in the ADRD arena given the long-term, progressive nature of the disease, its insidious socioeconomic impact beyond the patient and the formal healthcare system, and the complexities and current deficiencies (in measures and real-world data) in accurately calculating the full costs to society. There is therefore an urgent need for all stakeholders to establish a common understanding of the challenges in evaluating the full cost of ADRD and define approaches that allow us to measure these costs more accurately, with a view to prioritizing evidence-based solutions to mitigate this looming public health crisis.

Utilization and Cost Effects of the VHA Caring for Older Adults and Caregivers at Home (COACH) Program

Since 2010, the Veterans Health Administration has initiated a home-based Caring for Older Adults and Caregivers at Home (COACH) program to provide clinical support to dementia patients and family caregivers. But its impact on health care utilization and costs is unknown. We compared 354 COACH care recipients with a propensity score weighted comparison group of 9,857 community-dwelling Veterans during fiscal years 2010-2015. In 1-year follow-up, COACH program was associated with a lower rate of long-term nursing home placement (average treatment effect on the treated [ATT] -3%; p = .01). The program increased utilization of emergency services (ATT 6%; p = .01), hospitals (ATT 10%; p < .001), and personal care services (ATT 31%; p < .001). Health care costs were also significantly increased. Improved access to services may have enabled COACH Veterans to stay at home longer. As one of Veterans Health Administration's top priorities to expand caregiver assistance programs, COACH seems to be a promising model for a nationwide implementation.

Reduced Awareness of Memory Deficit is Associated With Increased Medicare Home Health Care Use in Dementia

OBJECTIVE

The objective of this study was to examine whether reduced awareness of memory deficits in individuals with dementia is associated with more frequent need for Medicare home health care services.

METHODS

Cross-sectional analyses were conducted in a multicenter, clinic-based cohort. In total, 192 participants diagnosed with dementia and their informants were independently asked whether or not the participant demonstrated cognitive symptoms of dementia related to memory and word-finding. Participant self-awareness was measured as the discrepancy between participant and caregiver report of these symptoms. Annual Medicare home health benefit use data was obtained from Medicare claims matched by year to the Predictors study visit.

RESULTS

Participants that used home health services had lower awareness scores than those who did not. Awareness remained independently associated with home health use in a logistic regression adjusted for age, gender, education, caregiver relationship, global cognition, dementia subtype, and medical comorbidities.

IMPLICATIONS

Reduced self-awareness of memory deficits in individuals with dementia is associated with more frequent use of Medicare home health services. The disproportionate use of in-home assistance as a function of awareness level may reflect dangers faced by patients, and challenges faced by caregivers, when patients have limited awareness of their memory deficits. Current results have implications for clinical care, caregiver education, and models of health care utilization.

2020 Alzheimer's disease facts and figures

This article describes the public health impact of Alzheimer's disease (AD), including incidence and prevalence, mortality and morbidity, use and costs of care, and the overall impact on caregivers and society. The Special Report discusses the future challenges of meeting care demands for the growing number of people living with Alzheimer's dementia in the United States with a particular emphasis on primary care. By mid-century, the number of Americans age 65 and older with Alzheimer's dementia may grow to 13.8 million. This represents a steep increase from the estimated 5.8 million Americans age 65 and older who have Alzheimer's dementia today. Official death certificates recorded 122,019 deaths from AD in 2018, the latest year for which data are available, making Alzheimer's the sixth leading cause of death in the United States and the fifth leading cause of death among Americans age 65 and older. Between 2000 and 2018, deaths resulting from stroke, HIV and heart disease decreased, whereas reported deaths from Alzheimer's increased 146.2%. In 2019, more than 16 million family members and other unpaid caregivers provided an estimated 18.6 billion hours of care to people with Alzheimer's or other dementias. This care is valued at nearly $244 billion, but its costs extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are more than three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 23 times as great. Total payments in 2020 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $305 billion. As the population of Americans living with Alzheimer's dementia increases, the burden of caring for that population also increases. These challenges are exacerbated by a shortage of dementia care specialists, which places an increasing burden on primary care physicians (PCPs) to provide care for people living with dementia. Many PCPs feel underprepared and inadequately trained to handle dementia care responsibilities effectively. This report includes recommendations for maximizing quality care in the face of the shortage of specialists and training challenges in primary care.

Feasibility of an at-home, web-based, interactive exercise program for older adults

Introduction

Increased physical exercise is linked to enhanced brain health and reduced dementia risk. Exercise intervention studies usually are conducted at facilities in groups under trainer supervision. To improve scalability, accessibility, and engagement, programs may need to be structured such that individuals can execute and adjust routines in their own homes.

Methods

One hundred eighty-three healthy older adults from two sites (the United States and Sweden) were screened. One hundred fifty-six subjects (mean age 73.2), randomly assigned to one of four interventions (PACE-Yourself physical exercise program, mindfulness meditation, or Cogmed® adaptive or nonadaptive computerized working memory training) began the study. All interventions were structurally similar: occurring in subjects' homes using interactive, web-based software, over five weeks, ∼175 minutes/week. In the PACE-Yourself program, video segments presented aerobic exercises at different pace and intensity (P&I). The program paused frequently, allowing subjects to indicate whether P&I was “too easy,” “too hard,” or “somewhat hard.” P&I of the subsequent exercise set was adjusted, allowing subjects to exercise at a perceived exertion level of “somewhat hard.” Program completion was defined as finishing ≥60% of sessions.

Results

A high percentage of participants in all groups completed the program, although the number (86%) was slightly lower in the PACE-Yourself group than the other three. Excluding dropouts, the PACE-Yourself group had a lower adherence rate of 93%, compared with the other three (∼98%). Over the five weeks, PACE-Yourself participants increased exercising at the highest intensity level, consistent with augmented aerobic activity over time. The number of exercise sessions completed predicted the postintervention versus preintervention increase in self-reported level of physical activity.

Discussion

This study supports the feasibility of a home-based, subject-controlled, exercise program in which P&I is regulated via real-time participant feedback, which may promote self-efficacy. Further study is needed to determine if similar results are found over longer periods and in more diverse populations.

•

Physical exercise is linked to enhanced brain health and reduced dementia risk.

•

PACE-Yourself is an interactive, web-based exercise program.

•

Its novel design allows participants to regulate exercise pace and intensity.

•

Older adults in the program had high completion and adherence rates.

•

PACE-Yourself may facilitate scalability and accessibility of exercise programs.

Using sensor-based technology for safety and independence - the experiences of people with dementia and their families

BACKGROUND

The majority of people with dementia prefer to live independently and safely in their own home cared for by their family members. Much effort has been invested in the development of technology, such as sensor-based networks. Many challenges remain, in particular gaining more knowledge about their experiences and perceived benefits. This study aimed to explore experiences, needs and benefits with using sensor-based technology for safety and independence in the homes of people with dementia and their family members.

METHODS

This study is part of the TECH@HOME project, aiming to evaluate the effects of sensor-based technology on independence among people with dementia and caregiver stress among their family members. This study applied an inductive, qualitative approach with semi-structured interviews of people with dementia (n = 9) and family members (n = 21). The participants were interviewed between June and September 2018 after using the technology for at least 6 months. The interviews were analysed with manifest content analysis.

RESULTS

Our findings highlighted that technology was considered as a precaution and a safety measure that could provide a sense of having control of the everyday life of the person with dementia. Understanding and acceptance of the technology were as important, together with the reliability of the technology. Ethical dilemmas related to the monitoring of the person with dementia in the home were also raised.

CONCLUSION

This study provides insights into how people with dementia and family members experience and benefit from using sensor-based technology in their own homes. The knowledge generated is essential for healthcare professionals and policymakers developing and implementing care and service systems including technology, as well as for the industry.

The direct and indirect financial costs of informal cancer care: A scoping review

Informal caregivers are the primary source of support for cancer patients, providing assistance with household tasks, medical care and emotional support. These responsibilities often result in high levels of emotional, physical, social and financial burden for the caregiver. The aim of this study was to perform a scoping review exploring what is known regarding the financial costs experienced by caregivers and identify gaps in the literature. Seven databases were searched for articles published between May 2008 and May 2018 related to direct and indirect costs of informal cancer care. Included articles reported on the costs incurred by cancer caregivers as a dollar value, relied on caregiver-reported costs and were peer reviewed. A total of 19 studies met the inclusion criteria. These studies reported out of pocket costs' opportunity costs of informal care time and caregiver time loss from paid employment. Care time was the largest source of cancer caregiver costs, averaging $4,809 per month when valued using the proxy good method or $2,877 per month when the opportunity cost approach was used. Caregiver costs were highest when the care recipient was in the palliative phase of the disease. There was an absence of literature reporting costs for cancer caregivers in low and middle income countries and none of the included studies considered costs related to the caregivers' medical expenditures. There were many challenges when comparing the costs across studies due to variations in the type of expenses reported and the methods used to value expenses. Quantifying the financial costs associated with being an informal caregiver can facilitate the communication of the financial burden caregivers experience, potentially spurring the development of policies and programs to reduce their financial burden and better support cancer caregivers.

Hospitalisation rates and predictors in people with dementia: a systematic review and meta-analysis

BACKGROUND

Hospitalisation is often harmful for people with dementia and results in high societal costs, so avoidance of unnecessary admissions is a global priority. However, no intervention has yet reduced admissions of community-dwelling people with dementia. We therefore aimed to examine hospitalisation rates of people with dementia and whether these differ from people without dementia and to identify socio-demographic and clinical predictors of hospitalisation.

METHODS

We searched MEDLINE, Embase, and PsycINFO from inception to 9 May 2019. We included observational studies which (1) examined community-dwelling people with dementia of any age or dementia subtype, (2) diagnosed dementia using validated diagnostic criteria, and (3) examined all-cause general (i.e. non-psychiatric) hospital admissions. Two authors screened abstracts for inclusion and independently extracted data and assessed included studies for risk of bias. Three authors graded evidence strength using Cochrane's GRADE approach, including assessing for evidence of publication bias using Begg's test. We used random effects meta-analysis to pool estimates for hospitalisation risk in people with and without dementia.

RESULTS

We included 34 studies of 277,432 people with dementia: 17 from the USA, 15 from Europe, and 2 from Asia. The pooled relative risk of hospitalisation for people with dementia compared to those without was 1.42 (95% confidence interval 1.21, 1.66) in studies adjusted for age, sex, and physical comorbidity. Hospitalisation rates in people with dementia were between 0.37 and 1.26/person-year in high-quality studies. There was strong evidence that admission is associated with older age, and moderately strong evidence that multimorbidity, polypharmacy, and lower functional ability are associated with admission. There was strong evidence that dementia severity alone is not associated.

CONCLUSIONS

People with dementia are more frequently admitted to hospital than those without dementia, independent of physical comorbidities. Future interventions to reduce unnecessary hospitalisations should target potentially modifiable factors, such as polypharmacy and functional ability, in high-risk populations.

The costs of dementia subtypes to California Medicare fee-for-service, 2015

INTRODUCTION

Dementia is among the costliest of medical conditions, but it is not known how these costs vary by dementia subtype.

METHODS

The effect of dementia diagnosis subtype on direct health care costs and utilization was estimated using 2015 California Medicare fee-for-service data. Potential drivers of increased costs in Lewy body dementia (LBD), in comparison to Alzheimer's disease, were tested.

RESULTS

3,001,987 Medicare beneficiaries were identified, of which 8.2% had a dementia diagnosis. Unspecified dementia was the most common diagnostic category (59.6%), followed by Alzheimer's disease (23.2%). LBD was the costliest subtype to Medicare, on average, followed by vascular dementia. The higher costs in LBD were explained in part by falls, urinary incontinence or infection, depression, anxiety, dehydration, and delirium.

DISCUSSION

Dementia subtype is an important predictor of health care costs. Earlier identification and targeted treatment might mitigate the costs associated with co-occurring conditions in LBD.

Evaluation of the perceived health of caregivers of patients in mild-to-moderate stage Alzheimer's disease

PURPOSE

To know the health perceived by the family caregivers of Alzheimer's disease, according to the relationship of kinship and the duration of the care in mild-to-moderate stage of dementia.

DESIGN AND METHODS

Cross-sectional descriptive study in 255 caregivers. The instruments used were an ad hoc questionnaire and the Goldberg General Health Questionnaire (GHQ-28).

FINDINGS

The presence of acute and chronic mental pathology has been observed. Specifically in the spouses and children, severe depression and social dysfunction, and in periods of care between 2 and 5 years, mainly anxiety and insomnia have been observed.

PRACTICE IMPLICATIONS

The relationship of kinship and the duration of care must be taken into account in the planning of specific interventions in these caregivers.

Development of a Brief Caregiver-centric Screening Tool to Identify Risk of Depression among Caregivers of Hospitalized Older Adults

OBJECTIVES

Caregivers of hospitalized older adults experience elevated levels of stress and are at risk of poor health outcomes. There is a lack of screening tools based on self-reported caregiver variables incorporating both protective and risk factors, for early identification of at-risk caregivers. This study reports the development of a caregiver-centric screening tool to identify risk of depression at admission and predicts 3-month risk of depression and quality of life amongst caregivers of older adults with an unplanned admission.

DESIGN, SETTING AND PARTICIPANTS

This prospective cohort study was conducted in the medical wards of a tertiary-care hospital from July 2015 to May 2017. We recruited family caregivers of patients aged 65 years and above who fulfilled the following criteria: a) unplanned admission, b) not residing in nursing homes; and c) requiring assistance in activities of daily living.

MEASUREMENTS

We examined 11 candidate caregiver variables (mastery, burden and nine demographic variables). Risk of depression (score ≥8 on Hospital Anxiety and Depression Scale (HADS-D) depression subscale) was the primary outcome, and was assessed during the index admission. Logistic regression models were used to identify risk factors and risk scores (weights). The total risk scores were then stratified into three risk levels. Predictive validity of the screening tool was assessed using 3-months post-discharge risk of depression and health-related quality of life (HRQoL).

RESULTS

The study included 274 caregiver-patient dyads. The mean (SD) age of the caregivers was 59 (10) years with 33.6% caregivers screening positive for risk of depression. The final model comprised three caregiver variables: mastery, burden and education. The total risk scores ranged from 0 to 6 and showed good discrimination (AUC:0.82, 95% CI: 0.77 to 0.87). Caregivers were classified into low-risk (0-1 points), intermediate-risk (2-4 points), and high-risk (5-6 points) groups, with corresponding rates of risk of depression (HADS-D≥8) of 10.7%, 44.6% and 73.3%, during admission. Relative risk rates of the intermediate- and high- risk group using the low-risk group as reference were 4.16 and 6.84 respectively. At 3-months post-discharge, the rates of caregivers at risk of depression or having poor HRQoL also increased corresponding to the three risk levels as per baseline, supporting the predictive validity of the tool.

CONCLUSIONS/IMPLICATIONS

The caregiver-centric tool is a novel, practical, self-administered, relatively brief caregiver-centric instrument that can be used for rapid screening and stratification of caregivers at risk of depression. Uniquely, the tool comprised of assessment of protective factor (mastery) in addition to risk factors to provide a holistic assessment of the caregiver. It can be incorporated as part of older adults' admission evaluation so that prompt intervention can be rendered to their at-risk caregivers.

We Are Caregivers: Social Identity Is Associated with Lower Perceived Stress among Rural Informal Caregivers

ABSTRACTInformal caregivers often experience high stress levels with little support, especially in rural settings. With a mixed-methods approach, this research explored experiences of rural informal caregivers, including how social identification as a caregiver, social interactions, and formal and informal coping support related to perceived stress. Major focus group themes (n = 8) included lacking available services, balancing challenges, unmet practical needs, and strong community identity. Survey data (n = 22) revealed that perceived coping support (e.g., having someone to turn to), social interactions, and caregiver identity (e.g., perceiving the role as important to one's self-concept) were associated with lower life upset stress, but only caregiver identity was associated with managing the personal distress and negative feelings associated with caregiving stress. Results suggest that, although available rural services may fall short, other options might alleviate caregiver stress, including facilitating access to coping support, encouraging social interactions, and enhancing caregiver social identity.

Mediating effect of spiritual coping strategies and family stigma stress on caregiving burden and mental health in caregivers of persons with dementia

Background A considerable number of the persons living with dementia rely on family members for care and assistance when performing activities of daily living. As a result, caregivers may be at increased risk for mental health problems such as depression, anxiety and caregiver burden. This study examined if and how spiritual coping and stigma-related family stress impacted the associations between the patient activities of daily living impairment and caregiver mental health. Methods Using a longitudinal design, 664 caregivers were assessed at baseline for spiritual coping strategies and family stigma stress, along with patients' instrumental activities of daily living and cognitive functioning. After 12 months, caregivers were assessed for depressive and anxiety symptoms, caregiver burden, and quality of life (physical and mental). Sequential mediation of spiritual coping strategies and stigma-related family stress on the relationship between patient instrumental activities of daily living and caregiver mental health outcomes was examined using the PROCESS macro statistical method. Results Participants had been caring for someone with dementia for an average of 46.4 (SD, 16.9) months and 63% of caregivers were female. There were significant indirect associations between patient instrumental activities of daily living and caregiver anxiety, depression, caregiving burden, and the mental health component of quality of life. Spiritual coping and stigma-related stress mediated these associations (-0.54 Collapse

Utility of the Dependence Scale in dementia: validity, meaningfulness, and health economic considerations

BACKGROUND

The concept of dependence has been proposed as a unified representation of disease severity to quantify and stage disease progression in a manner more informative to patients, caregivers, and healthcare providers.

METHODS

This paper provides a review of the Dependence Scale (DS) as a quantitative measure of Alzheimer's disease severity, its properties as an outcome measure, a metric of disease progression, and a correlate of medical costs.

RESULTS

The literature supports the notion that the DS is related to, but distinct from, key severity measures, including cognition, function, and behavior, and captures the full spectrum of patient needs. It also presents as a useful measure for assessing disease progression.

CONCLUSIONS

Results underscore the importance of the DS as a unique endpoint in Alzheimer's disease clinical trials, providing important information about the impact of therapeutic interventions. The DS also is a useful measure for economic evaluation of novel interventions aimed at delaying progression.

A cross-sectional study of family caregiver burden and psychological distress linked to frailty and functional dependency of a relative with advanced dementia

Psychological health of caregivers of people with dementia is a major public concern. This study sought to determine the relationship between caregiver burden, psychological distress, frailty and functional dependency of a relative with advanced dementia. Persons with dementia and their caregivers (102 dyads) participated in this Portuguese community based cross-sectional study. Data were collected using the Clinical Dementia Rating Scale, a sociodemographic questionnaire, the Zarit Burden Interview, the Brief Symptoms Inventory and the Edmonton Frail Scale. Alzheimer's disease was the most common type of dementia among the recipients of care, who showed moderate (42.2%) to severe (52.9%) dementia. Among them 35.3% exhibited moderate and 45.1% severe frailty. Family caregivers reported moderate (76.5%) to severe burden (18.6%). Psychological distress was very high among family caregivers. Results show that people with dementia exhibited moderate (35.3%) or severe frailty (45.1%) and that a severe frailty was found in people with moderate dementia. A one-way ANOVA was conducted between the Global Severity Index and some sociodemographic variables. ANOVA reached p < .01 for employment status of the caregiver, assistance and professional support, and psychiatric history; and p = 0.01 for caregiver age and years of caregiving. Although caregivers reported benefit from the supportive approach offered by the multidisciplinary home care team, high levels of distress and associated burden were found, which might decrease their capacity to care for the person with dementia and their own health and well-being.

Perspectives and Insights from Vietnamese American Mental Health Professionals on How to Culturally Tailor a Vietnamese Dementia Caregiving Program

OBJECTIVE

Little is known about dementia and caregiving among the rapidly growing Vietnamese American population. This qualitative study elicited insights on culturally tailoring an intervention to address mental health needs in Vietnamese American dementia caregivers from Vietnamese American mental health professionals.

METHODS

Eight Vietnamese American mental health professionals were interviewed to explore: experiences working with and needs of the community; Vietnamese attitudes toward treatment; and acculturation in Vietnamese caregiving. Participants provided recommendations on tailoring a program for Vietnamese dementia caregivers. Content analysis of their responses was conducted.

RESULTS

Themes included: a) caregivers' unique needs and experiences; b) different waves of immigration and acculturation levels affect views on mental health, treatment, and caregiving; c); traditions and beliefs on caregiving; d) mental health, help-seeking and health services; e) how to culturally tailor a program for Vietnamese dementia caregivers; and f) cultural acceptance of the program.

CONCLUSIONS

An intervention to reduce stress and depression among Vietnamese American dementia caregivers should recognize the special risks of the experiences of war and immigration of the caregivers as well as the pressure of the expectations of the Vietnamese culture on family care. For the program to be acceptable and effective, it needs to consider all aspects of caregivers' health, and incorporate Vietnamese cultural values/beliefs.

CLINICAL IMPLICATIONS

A successful Vietnamese dementia caregiver intervention should include traditional Vietnamese values/beliefs, holistic experiences, spirituality, and background/immigration experiences. Evidence-based programs may be used with this population if they are culturally tailored.

Life Enhancing Activities for Family Caregivers of people with dementia: protocol for a randomized controlled trial of a positive affect skills intervention

Given the increasing number of family caregivers of persons with dementia (PWD) and the associated burden and detriments to both physical and mental health, interventions that aim to improve such outcomes are important. Studies are increasingly demonstrating the unique importance of positive emotions in coping with stress, independent from the impact of negative emotions. However, none have examined the benefits of interventions that target positive emotions for caregivers of individuals with a chronic and debilitating disease such as dementia. This paper presents the design and methods for a randomized controlled trial (RCT) of a positive affect skills intervention for family caregivers of PWD. The RCT is of a skills-based intervention that seeks to increase the frequency and intensity of positive affect in order to improve outcomes such as well-being, coping, and physical and mental health. The skills are delivered by trained facilitators via five one-to-one Internet video sessions with family caregivers of persons diagnosed with dementia (eg, Alzheimer's disease, vascular dementia, unspecified). The control group is an emotion reporting/waitlist control. Follow-up assessments are conducted post-intervention and at 1, 3, and 6 months post-completion of the intervention. This study promises to be an important and needed step toward improving the lives of caregivers of PWD.

Supporting carers of people with dementia: What is effective?

Carer stress is well documented, especially in those caring for individuals with dementia. A recommendation of all national dementia strategies is to provide excellent support and information to informal carers of people with dementia. NICE guidance suggests that a range of tailored interventions, including psychological input, psychoeducation and training courses, should be offered to reduce caregiver burden and stress, although good-quality outcome-based evidence is lacking. On the basis of a narrative review of the literature, we describe individual and multicomponent carer support packages and discuss their evidence base, reflecting on outcomes for carers. Multicomponent interventions have the best evidence for effectiveness.

Learning Objectives

• Consider the risks of both physical and psychological harm experienced by carers of people with dementia (often referred to as carer burden or caregiver burden)

• Be aware of the interventions available for the support of carers of people with dementia

• Consider the evidence for the effectiveness of these interventions and be aware of the limitations of the evidence

Increasing Burden of Complex Multimorbidity Across Gradients of Cognitive Impairment

INTRODUCTION

This study evaluates the burden of multimorbidity (MM) across gradients of cognitive impairment (CI).

METHODS

Using data from the 2010 Health and Retirement Study, we identified individuals with no CI, mild CI, and moderate/severe CI. In addition, we adopted an expansive definition of complex MM by accounting for the occurrence and co-occurrence of chronic conditions, functional limitations, and geriatric syndromes.

RESULTS

In a sample of 18 913 participants (weighted n = 87.5 million), 1.93% and 1.84% presented with mild and moderate/severe CI, respectively. The prevalence of most conditions constituting complex MM increased markedly across the spectrum of CI. Further, the percentage of individuals presenting with 10 or more conditions was 19.9%, 39.3%, and 71.3% among those with no CI, mild CI, and moderate/severe CI, respectively.

DISCUSSION

Greater CI is strongly associated with increased burden of complex MM. Detailed characterization of MM across CI gradients will help identify opportunities for health care improvement.

Caregiver Experiences Across Three Neurodegenerative Diseases: Alzheimer’s, Parkinson’s, and Parkinson’s With Dementia

Objective: This article asks whether distinct caregiver experiences of Alzheimer’s disease (AD), Parkinson’s disease (PD), and Parkinson’s disease with dementia (PDD) spouses are accounted for by disease diagnosis or by a unique combination of symptoms, demands, support, and quality of life (QOL) cross disease groups. Method: One hundred five live-in spouse caregivers (71.4 ± 7 years) were surveyed for persons with AD (39%), PD (41%), and PDD (20%). A hierarchical cluster analysis organized caregivers across disease diagnosis into clusters with similar symptom presentation, care demands, support, and QoL. Results: Four clusters cut across disease diagnosis. “Succeeding” cared for mild symptoms and had emotional support. “Coping” managed moderate stressors and utilized formal supports. “Getting by with support” and “Struggling” had the greatest stressors; available emotional support influenced whether burden/depression was moderate or severe. The results remain the same when diagnostic category is added to the cluster analysis. Discussion: This study supports going beyond disease diagnosis when examining caregiver experiences.

The social and economic burden of frontotemporal degeneration

Objective:

To quantify the socioeconomic burden of frontotemporal degeneration (FTD) compared to previously published data for Alzheimer disease (AD).

Methods:

A 250-item internet survey was administered to primary caregivers of patients with behavioral-variant FTD (bvFTD), primary progressive aphasia, FTD with motor neuron disease, corticobasal syndrome, or progressive supranuclear palsy. The survey included validated scales for disease staging, behavior, activities of daily living, caregiver burden, and health economics, as well as investigator-designed questions to capture patient and caregiver experience with FTD.

Results:

The entire survey was completed by 674 of 956 respondents (70.5%). Direct costs (2016 US dollars) equaled $47,916 and indirect costs $71,737, for a total annual per-patient cost of $119,654, nearly 2 times higher than reported costs for AD. Patients ≥65 years of age, with later stages of disease, and with bvFTD correlated with higher direct costs, while patients <65 years of age and men were associated with higher indirect costs. An FTD diagnosis produced a mean decrease in household income from $75,000 to $99,000 12 months before diagnosis to $50,000 to $59,999 12 months after diagnosis, resulting from lost days of work and early departure from the workforce.

Conclusions:

The economic burden of FTD is substantial. Counting productivity-related costs, per-patient costs for FTD appear to be greater than per-patient costs reported for AD. There is a need for biomarkers for accurate and timely diagnosis, effective treatments, and services to reduce this socioeconomic burden.

Factors associated with living situation among Alzheimer's caregivers in the south of Spain that affect the election of external support services

Alzheimer’s is a syndrome mainly suffered by women and the care they need is also mainly provided by other women. The aim of this paper is to describe the profile of users of professional support services and to find out if some socio-demographic factors are linked with those elections. The study was conducted from January to June 2012 thanks to the cooperation of over 41 Alzheimer’s Associations in Andalusia, in the south of Spain. A person trained by the main researcher (a social worker or a psychologist) completed the questionnaire during an interview with the caregiver. Seven hundred and seventy-eight questionnaires were analysed. Contrary to previous findings, the use of external services is not infrequent. The most commonly used services are Day Care Centres (22.4%) and Cognitive Workshops (19.2%), but Home Assistance Services are the most frequently used either alone or in combination with the other two (27.5%). A higher level of education increases the probability of choosing a nursing home. The two main factors for looking for external support are non-cohabitation and working outside the home. Among caregivers under 40 years old this is the main profile. Using no services or in low and medium intensity in service hours leads to informal caregivers being the main caregivers. The potential labour market for professional caring is reduced by a crowding-out effect. Employment reduces the chance of being a caregiver.

Examining Factors Affecting Caregiver Burden: A Comparison of Frontotemporal Dementia and Alzheimer's Disease

This study was conducted to compare the caregiver burden with regard to Alzheimer's disease (AD) and frontotemporal dementia (FTD) and to determine the factors affecting the caregiver burden of patients with AD and FTD. A comparative descriptive study design was used. The sample consisted of 90 patients with AD and 44 patients with FTD and their caregivers. Sociodemographic questionnaire, Mini-Mental State Examination (MMSE), the Caregiver Burden Inventory (CBI), Neuropsychiatric Inventory (NPI), and Functional Activities Questionnaire (FAQ) were used. Descriptive statistics, t tests, χ2 test, and multinominal regression were used for analysis. No difference was found with subscales and the total score of the CBI, except time dependency scale. The total NPI and FAQ scores correlated significantly, and the MMSE score did not show a significant correlation with the AD and FTD caregiver burden. The presence and frequency of neuropsychological symptoms differ among patients with FTD and AD, and different symptoms affect the caregiver burdens in both groups.

Direct and indirect cost of managing alzheimer's disease and related dementias in the United States

INTRODUCTION

Care of individuals with Alzheimer's Disease and Related Dementias (ADRD) poses special challenges. As the disease progresses, individuals with ADRD require increasing levels of medical care, caregiver support, and long-term care which can lead to substantial economic burden. Areas covered: In this expert review, we synthesized findings from studies of costs of ADRD in the United States that were published between January 2006 and February 2017, highlighted major sources of variation in costs, identified knowledge gaps and briefly outlined directions for future research and implications for policy and program planning. Expert commentary: A consistent finding of all studies comparing individuals with and without ADRD is that the average medical, non-medical, and indirect costs of individuals with ADRD are higher than those without ADRD, despite the differences in the methods of identifying ADRD, duration of the study, payer type and settings of study population. The economic burden of ADRD may be underestimated because many components such as direct non-medical costs for home safety modifications and adult day care services and indirect costs due to the adverse impact of ADRD on caregivers' health and productivity are not included in cost estimates.

2016 Alzheimer's disease facts and figures

This report describes the public health impact of Alzheimer's disease, including incidence and prevalence, mortality rates, costs of care, and the overall impact on caregivers and society. It also examines in detail the financial impact of Alzheimer's on families, including annual costs to families and the difficult decisions families must often make to pay those costs. An estimated 5.4 million Americans have Alzheimer's disease. By mid-century, the number of people living with Alzheimer's disease in the United States is projected to grow to 13.8 million, fueled in large part by the aging baby boom generation. Today, someone in the country develops Alzheimer's disease every 66 seconds. By 2050, one new case of Alzheimer's is expected to develop every 33 seconds, resulting in nearly 1 million new cases per year. In 2013, official death certificates recorded 84,767 deaths from Alzheimer's disease, making it the sixth leading cause of death in the United States and the fifth leading cause of death in Americans age ≥ 65 years. Between 2000 and 2013, deaths resulting from stroke, heart disease, and prostate cancer decreased 23%, 14%, and 11%, respectively, whereas deaths from Alzheimer's disease increased 71%. The actual number of deaths to which Alzheimer's disease contributes is likely much larger than the number of deaths from Alzheimer's disease recorded on death certificates. In 2016, an estimated 700,000 Americans age ≥ 65 years will die with Alzheimer's disease, and many of them will die because of the complications caused by Alzheimer's disease. In 2015, more than 15 million family members and other unpaid caregivers provided an estimated 18.1 billion hours of care to people with Alzheimer's and other dementias, a contribution valued at more than $221 billion. Average per-person Medicare payments for services to beneficiaries age ≥ 65 years with Alzheimer's disease and other dementias are more than two and a half times as great as payments for all beneficiaries without these conditions, and Medicaid payments are 19 times as great. Total payments in 2016 for health care, long-term care and hospice services for people age ≥ 65 years with dementia are estimated to be $236 billion. The costs of Alzheimer's care may place a substantial financial burden on families, who often have to take money out of their retirement savings, cut back on buying food, and reduce their own trips to the doctor. In addition, many family members incorrectly believe that Medicare pays for nursing home care and other types of long-term care. Such findings highlight the need for solutions to prevent dementia-related costs from jeopardizing the health and financial security of the families of people with Alzheimer's and other dementias.

Dementia Caregiver Burden: a Research Update and Critical Analysis

PURPOSE OF REVIEW

This article provides an updated review of the determinants of caregiver burden and depression, with a focus on care demands and especially the differential effects of various neuropsychiatric symptoms or symptom clusters. Moreover, studies on caregivers for frontotemporal and Lewy body dementias were referred to in order to identify differences and similarities with the mainstream literature based largely on Alzheimer caregivers.

RECENT FINDINGS

As a group, neuropsychiatric symptoms are most predictive of caregiver burden and depression regardless of dementia diagnosis, but the effects appear to be driven primarily by disruptive behaviors (e.g., agitation, aggression, disinhibition), followed by delusions and mood disturbance. Disruptive behaviors are more disturbing partly because of the adverse impact on the emotional connection between the caregiver and the care-recipient and partly because they exacerbate difficulties in other domains (e.g., caring for activities of daily living). In behavioral variant frontotemporal dementia, not only are these disruptive behaviors more prominent but they are also more disturbing due to the care-recipient's insensitivity to others' feelings. In Lewy body dementia, visual hallucinations also appear to be distressing. The disturbing nature of disruptive behaviors cuts across dementia conditions, but the roles played by symptoms that are unique or particularly serious in a certain condition need to be explored further.

Financial Care for Older Adults With Dementia

This article describes an examination of the sociodemographic characteristics of adult children, particularly Baby Boomer caregivers, who provide financial care to older parents with dementia. The sample including 1,011adult children dementia caregivers aged 50 to 64 years is selected from a nationally representative sample in the 2010 Health and Retirement Study. Exact logistic regression revealed that race, provision of financial assistance to caregiver children, and the number of their children are significantly associated with financial caregiving of parents. Non-White caregivers are more likely to provide financial care to their parents or parents-in-law with dementia; those who have more children and provide financial assistance to their children are less likely to provide financial care to parents with dementia. The current findings present valuable new information on the sociodemographic characteristics of adult children who provide financial assistance to parents with dementia and inform research, programs, and services on dementia caregiving.

Randomized Trial of the Family Intervention: Telephone Tracking-Caregiver for Dementia Caregivers: Use of Community and Healthcare Resources

OBJECTIVES

To examine the effects of a telephone-delivered intervention, Family Intervention: Telephone Tracking-Caregiver (FITT-C), on community support and healthcare use by dementia caregivers.

DESIGN

Randomized, controlled trial.

SETTING

Academic medical center.

PARTICIPANTS

Dyads (n = 250) of distressed informal dementia caregivers and care recipients.

INTERVENTION

Caregivers were randomly assigned to receive the FITT-C (n = 133) or telephone support (TS; n = 117). Both groups received 16 telephone contacts from a master's-level therapist over 6 months. The FITT-C intervention provided psychoeducation, problem solving, and other directive approaches based on assessment of critical areas (e.g., mood, behavior, family functioning, social support). TS provided supportive therapeutic strategies.

MEASUREMENTS

Outcome variables were caregiver report of community support service use, number of visits to the emergency department (ED) for caregivers and care recipients, and hospital stays for caregivers during the interventions.

RESULTS

Intervention groups did not differ in demographic characteristics, use of support services, or use of healthcare resources at baseline. Caregivers who received the FITT-C used community support services at end of treatment significantly more than those receiving TS (P = .02). FITT-C caregivers had a significantly lower rate of ED visits (rate difference 9.5%, P = .048) and hospital stays (rate difference 11.4%, P = .01) over the 6-month course of the intervention than TS caregivers. Care recipient use of community or medical resources did not differ according to group.

CONCLUSION

An entirely telephone-delivered intervention was effective in increasing caregiver engagement in community resources and reducing caregiver use of hospital-based healthcare resources. Results highlight the potential effect of FITT-C on healthcare use.

Health, social and economic consequences of dementias: a comparative national cohort study

BACKGROUND AND PURPOSE

Dementia causes morbidity, disability and mortality, and as the population ages the societal burden will grow. The direct health costs and indirect costs of lost productivity and social welfare of dementia were estimated compared with matched controls in a national register based cohort study.

METHODS

Using records from the Danish National Patient Registry (1997-2009) all patients with a diagnosis of Alzheimer's disease, vascular dementia or dementia not otherwise specified and their partners were identified and compared with randomly chosen controls matched for age, gender, geographical area and civil status. Direct health costs included primary and secondary sector contacts, medical procedures and medication. Indirect costs included the effect on labor supply. All cost data were extracted from national databases. The entire cohort was followed for the entire period - before and after diagnosis.

RESULTS

In all, 78 715 patients were identified and compared with 312 813 matched controls. Patients' partners were also identified and matched with a control group. Patients had lower income and higher mortality and morbidity rates and greater use of medication. Social- and health-related vulnerability was identified years prior to diagnosis. The average annual additional cost of direct healthcare costs and lost productivity in the years before diagnosis was 2082 euros per patient over and above that of matched controls, and 4544 euros per patient after the time of diagnosis.

CONCLUSIONS

Dementias cause significant morbidity and mortality, consequently generating significant socioeconomic costs.

Effect of diabetes on caregiver burden in an observational study of individuals with Alzheimer's disease

Background

The burden on caregivers of patients with Alzheimer’s disease (AD) is associated with the patient’s functional status and may also be influenced by chronic comorbid medical conditions, such as diabetes. This post-hoc exploratory analysis assessed whether comorbid diabetes in patients with AD affects caregiver burden, and whether caregivers with diabetes experience greater burden than caregivers without diabetes. Caregiver and patient healthcare resource use (HCRU) were also assessed.

Methods

Baseline data from the GERAS observational study of patients with AD and their caregivers (both n = 1495) in France, Germany and the UK were analyzed.

Caregiver burden was assessed using the Zarit Burden Interview (ZBI). Caregiver time on activities of daily living (ADL: basic ADL; instrumental ADL, iADL) and supervision (hours/month), and caregiver and patient HCRU (outpatient visits, emergency room visits, nights hospitalized) were assessed using the Resource Utilization in Dementia instrument for the month before the baseline visit. Regression analyses were adjusted for relevant covariates. Time on supervision and basic ADL was analyzed using zero-inflated negative binomial regression.

Results

Caregivers of patients with diabetes (n = 188) were younger and more likely to be female (both p < 0.05), compared with caregivers of patients without diabetes (n = 1307). Analyses showed caregivers of patients with diabetes spent significantly more time on iADL (+16 %; p = 0.03; increases were also observed for basic ADL and total caregiver time but did not reach statistical significance) and had a trend towards increased ZBI score. Patients with diabetes had a 63 % increase in the odds of requiring supervision versus those without diabetes (p = 0.01). Caregiver and patient HCRU did not differ according to patient diabetes.

Caregivers with diabetes (n = 127) did not differ from those without diabetes (n = 1367) regarding burden/time, but caregivers with diabetes had a 91 % increase in the odds of having outpatient visits (p = 0.01).

Conclusions

This cross-sectional analysis found caregiver time on iADL and supervision was higher for caregivers of patients with AD and diabetes versus without diabetes, while HCRU was unaffected by patient diabetes. Longitudinal analyses assessing change in caregiver burden over time by patient diabetes status may help clarify the cumulative impact of diabetes and AD dementia on caregiver burden.
