Do caregiver interventions improve outcomes in relatives with dementia and mild cognitive impairment? A comprehensive systematic review and meta-analysis

Evidence Map of Non-Pharmacological Dementia Care Partner Interventions Implemented in the US: Gaps and Impact Opportunities

There are 200+ tested interventions for care partners (family, friends, and fictive kin) of people living with dementia (PLWD). But these interventions do not systematically cover relevant settings. Nor do these interventions affect all relevant outcomes that matter to people and healthcare systems. We present an evidence map of settings and outcomes from translated interventions to identify gaps. Of 190 studies identified, 31 unique interventions were retained in the evidence map. Identified setting gaps included studies set solely in hospitals/medical centers or set in multiple settings. Identified outcome gaps included interventions that improved care partner beliefs about providing care, care partner negative coping strategies, PLWD resources (e.g., social support), and PLWD coping strategies. Armed with an understanding of present gaps, we call on researchers to fill the identified gaps to ensure systematic coverage of settings and evaluation of outcomes that matter to people and healthcare systems.

Effects of Activities on the Psychological Well-Being of Caregivers of Older Adults: A Systematic Review

Given that approximately 41.8 million Americans provide unpaid care to older adults and caregiving roles are often associated with decreased well-being, it is critical to identify strategies to maximize their well-being. The purpose of this review was to explore which activities significantly improve well-being among caregivers of older adults. A systematic literature review was conducted using PsycINFO and 24 research articles met inclusion criteria and were included in the final analysis. Eight cohesive activity categories were identified: Social (n = 5), Psychoeducation (n = 3), Arts/entertainment in the home (n = 2), Psychotherapy (n = 5), Religious/Spiritual (n = 4), Multimodal (n = 4), Physical (n = 5), and Arts/entertainment outside the home (n = 2). Findings suggest that caregivers of older adults should seek opportunities for engagement in meaningful activities, particularly social, psychoeducational activities, arts/entertainment activities in the home, which showed positive impacts, as well as psychotherapy, religious/spiritual, multimodal, and physical activities, which showed mixed impacts on caregivers' psychological well-being.

Ambivalent Feelings and Relationship Quality in Dementia Family Caregivers: Associations with Depressive Symptomatology

OBJECTIVES

Ambivalent feelings in dementia family caregivers have been found to be related to caregivers´ stress associated with the behavioral and psychological symptoms of dementia (BPSD-related stress), and depressive symptoms. Ambivalent feelings may also affect caregivers´ perceived quality of the relationship with the person living with dementia (PLwD), but this variable has been scarcely studied. This study analyzes the role of ambivalent feelings in the association between caregivers' BPSD-related stress, perceived quality of the relationship with the PLwD, and depressive symptomatology.

METHODS

A theoretical model was developed and tested in a sample of 390 family caregivers.

RESULTS

The obtained tested model had an excellent fit to the data, explaining 24% of the variance of depressive symptomatology. A significant association was found between caregivers' BPSD-related stress, ambivalent feelings, and depressive symptomatology. Also, an indirect effect in the association between ambivalent feelings and depressive symptomatology was found through the perceived quality of the relationship.

CONCLUSIONS

Ambivalent feelings in dementia family caregivers are associated with caregivers' BPSD-related stress, perception of a lower relationship quality, and higher depressive symptomatology.

CLINICAL IMPLICATIONS

Targeting caregivers' ambivalent feelings and the quality of the relationship in interventions for dementia family caregivers may decrease their distress.

Effectiveness of interventions for informal caregivers of community-dwelling frail older adults: A systematic review and meta-analysis

AIM

Systematic reviews on interventions for informal caregivers of community-dwelling frail older adults were published over a decade ago and they mistook frailty for other severe age-related conditions like disability and dementia. Therefore, this study aimed to systematically synthesize these interventions supporting these caregivers identified by an acknowledged frailty assessment instrument and to examine their effectiveness on caregiver-related outcomes.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Fourteen electronic databases, grey literature and reference lists were systematically searched for randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) from inception to November 3, 2023.

METHODS

Methodology quality and risk of bias were assessed. Data were meta-analysed using the Comprehensive Meta-Analysis, version 3.0. Studies and outcomes unsuitable for meta-analysis were summarized by narrative syntheses.

RESULTS

Four studies consisting of three RCTs and one NRCT were included involving 350 participants. Interventions for caregivers of frail older adults included multicomponent interventions (n = 3) and education intervention (n = 1). Interventions had a moderate effect on reducing depression and showed nonsignificant effects on caregiver burden, caregiving time or quality of life (QoL). The PEDro scores for RCTs ranged from 6 to 8, indicating good methodologic quality, but were all judged as high risk of bias. The NRCT reported all methodologic aspects and was at low risk of bias.

CONCLUSIONS

Few studies focus on interventions targeting caregivers of frail older adults, and their effectiveness may vary by outcomes. This review suggested the potential benefits of these interventions in reducing caregivers' depression.

IMPACT

The differential effectiveness by outcomes and high risk of bias of studies implicate that more rigorous studies are warranted.

Transforming the discharge conversation through support and structure: A scoping review

Background

System level demands and interpersonal barriers can disrupt nurse delivery of high-quality information at discharge, which can contribute to a lack of caregiver preparedness to manage care of the patient and ultimately affect patient health.

Objective

To synthesize evidence on effective nurse communication with informal caregivers during hospital discharge of adult patients with cognitive decline or Alzheimer's disease and related dementia.

Design

A scoping review of inpatient nurse communication with informal caregivers.

Methods

Collected research (published between 2011 and 2023) from three databases (MEDLINE, PsycINFO, and CINAHL), along with a separate search for gray literature (N = 18), to extract and synthesize recommended communication practices evidenced to improve the nurse care experience and support caregiver activation and preparedness.

Results

Extraction synthesis of strategies resulted in two themes with corresponding sub-themes: Support (Information exchange, Space and time to determine preparedness, and Positive reinforcement of caregiver efforts) and Structure (Setting shared expectations, Informational resources, and Standardization).

Conclusions

We offer practical recommendations for both interpersonal and policy level facilitation of nurse delivery of high-quality information at discharge to caregivers of patients with serious illness.

2024 Alzheimer's disease facts and figures

This article describes the public health impact of Alzheimer's disease (AD), including prevalence and incidence, mortality and morbidity, use and costs of care and the ramifications of AD for family caregivers, the dementia workforce and society. The Special Report discusses the larger health care system for older adults with cognitive issues, focusing on the role of caregivers and non-physician health care professionals. An estimated 6.9 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060, barring the development of medical breakthroughs to prevent or cure AD. Official AD death certificates recorded 119,399 deaths from AD in 2021. In 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death, Alzheimer's was the seventh-leading cause of death in the United States. Official counts for more recent years are still being compiled. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2021, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 140%. More than 11 million family members and other unpaid caregivers provided an estimated 18.4 billion hours of care to people with Alzheimer's or other dementias in 2023. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $346.6 billion in 2023. Its costs, however, extend to unpaid caregivers' increased risk for emotional distress and negative mental and physical health outcomes. Members of the paid health care and broader community-based workforce are involved in diagnosing, treating and caring for people with dementia. However, the United States faces growing shortages across different segments of the dementia care workforce due to a combination of factors, including the absolute increase in the number of people living with dementia. Therefore, targeted programs and care delivery models will be needed to attract, better train and effectively deploy health care and community-based workers to provide dementia care. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2024 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $360 billion. The Special Report investigates how caregivers of older adults with cognitive issues interact with the health care system and examines the role non-physician health care professionals play in facilitating clinical care and access to community-based services and supports. It includes surveys of caregivers and health care workers, focusing on their experiences, challenges, awareness and perceptions of dementia care navigation.

Longitudinal effects of ambivalent and guilt feelings on dementia family caregivers' depressive symptoms

BACKGROUND

The world prevalence of people with dementia is increasing. Most of the care received by people with dementia is provided by family caregivers, and this prolonged activity has a significant impact on caregivers' levels of depression. Stressors and frequency of leisure are known predictors of caregivers' depressive levels. The longitudinal impact of caregivers' ambivalent and guilt feelings is unknown.

METHODS

Participants were 177 family caregivers of relatives with dementia who were assessed three times during a 2-year period. In addition to demographic variables, psychological symptoms of the dementias, and frequency of leisure activities, caregivers' ambivalent feelings, guilt, and depressive symptoms were measured. The longitudinal association of changes in these variables with changes in caregivers' depressive symptoms over time was assessed using mixed linear models.

RESULTS

Changes over time in the assessed variables predicted 48.05% of variance of changes over time in depressive symptoms. Even when variables strongly associated with increased depressive symptoms were controlled (lower caregivers' age and educational level, higher reaction to BPSD, and lower leisure activities), increases in ambivalence and guilt contributed to an increase of 9.22% of the variance of changes depressive symptoms over a 2-year period. The effects of ambivalent feelings on depression are indirect, mediated by guilt feelings. Cessation of caregiving do not seem to alter these findings.

CONCLUSIONS

Caregivers' ambivalent and guilt feelings are significant predictors of caregivers' mental health. Caregivers may significantly benefit from early detection of ambivalent and guilt feelings and preventive strategies targeting triggers associated with ambivalent and guilt symptoms.

Neuropsychiatric Symptoms Predict Faster Cognitive Decline in Dementia Collaborative Care Than Antipsychotic Use

Background

To compare short-term cognitive outcomes among groups with and without neuropsychiatric symptoms (NPSs) or antipsychotic prescription and to determine which disease status or treatment modality is associated with relatively faster cognitive decline.

Methods

We retrospectively analyzed a prospective cohort of patients diagnosed with dementia and mild cognitive impairment. All participants were evaluated using the Cognitive Abilities Screening Instrument (CASI) during their initial clinical assessments and at the annual follow-up. The dependent variable was annual delta CASI. Multivariate linear regression analysis was used to assess the degree of association between NPS, antipsychotic use, and cognitive decline after adjusting for confounding factors. Neuropsychiatric symptoms were examined individually to determine their predictive value for cognitive decline.

Results

A total of 407 (N = 407) patients were included in the study. NPSs, rather than antipsychotic use, led to faster cognitive decline. A higher baseline NPI total score predicted a significantly faster decline in CASI scores (1-year delta CASI = -0.22, 95% CI = -0.38~ -0.05, p = 0.010). Specific items (delusions, agitation, depression, anxiety, euphoria, and apathy) in the NPS significantly increased cognitive decline.

Conclusion

Certain neuropsychiatric symptoms, rather than antipsychotic use, lead to faster cognitive decline in a dementia collaborative care model. Checking for and providing appropriate interventions for NPS in people with dementia and their caregivers are highlighted.

Dementia care and prevention in community settings: a built environment framework for cognitive health promotion

PURPOSE OF REVIEW

Most people with dementia live in the community. As lifespan increases, one in three persons aged 85+ are expected to live with dementia. We conduct a systematic search to identify frameworks for dementia care and prevention in community settings. This is important to ensure quality of life for people living with cognitive decline (PLCD).

RECENT FINDINGS

61 frameworks are synthesized into the dementia care and prevention in community (DCPC) framework. It highlights three levels of provision: built environment and policy supports, access and innovation, and inclusion across stages of decline. Domains of intervention include: basic needs; built environment health and accessibility; service access and use; community health infrastructure; community engagement; mental health and wellbeing; technology; end-of-life care; cultural considerations; policy, education, and resources. Personhood is not adequately represented in current built environment frameworks. This is supplemented with 14 articles on lived experiences at home and social practices that contribute to PLCD's social identity and psychological safety.

SUMMARY

Policy makers, health and built environment professionals must work together to promote "personhood in community" with PLCD. Clinicians and community staff may focus on inclusion, social identity and a sense of at-homeness as attainable outcomes despite diagnosis.

The quality of family relationships in dementia: Mixed methods to unravel mixed feelings

Objective: Close relationships influence health and quality of life outcomes for people with dementia and their families. Yet, we know little on the role of different relationship domains with quantitative methods having proved to have limitations in this research field. We aimed to study these relationship domains over time, contrasting the views of people with dementia and their family carers, making use of both quantitative and qualitative approaches.Methods: A convergent mixed methods design was adopted, analysing longitudinal data (four time points over three years) from 66 dyads of Portuguese community-dwelling people with dementia and their primary carers, from the EU-Actifcare project sample. Quantitative assessments used sociodemographic and clinical variables, and Positive Affect Index scores, with descriptive and inferential analyses. Qualitative data, collected through individual and joint semi-structured interviews, were explored using thematic analysis.Results: Both quantitative and qualitative findings demonstrated that some domains of relationship quality are affected in different ways, with changes occurring at different stages. Some (e.g., 'communication') may even improve after initial decline. 'Closeness' was consistently altered over time, from carers' perspectives, and played an important protective role regarding institutionalisation. Overall, changes in the relationship quality were perceived differently by people with dementia and their carers, and these divergent perspectives often led to tension. Qualitative data revealed that 'mixed feelings' (ambivalence) involve complex experiences, arguably more difficult to manage than negative feelings alone. Furthermore, perceived informal support, particularly from the extended family, and receiving formal services' assistance, seemed to facilitate positive (re)appraisals of the relationship.Conclusions: A deeper understanding of relationship quality and its domains as dementia progresses may help tailoring interventions to tackle modifiable aspects of relationships, meeting the needs and cherishing the resources of dyads and families. Timely assessments could identify relationships at risk and need for support, including for alternative caring arrangements.

Counseling regarding the care of people with dementia with a focus on §7a SGB XI in Germany: a "gray-shaded" scoping review

BACKGROUND

Care counseling is an important psychosocial intervention for people with care needs and their relatives and can contribute to maintaining and/or improving a patient's quality of life and reducing the burden of caregivers. This is especially the case for people with dementia and their relatives, in which the methods of care counseling need to be different than those for individuals with non-dementia related care needs. Furthermore, the counseling content needs to be adjusted to the specific form and stage of dementia. In Germany, every person who receives support per the German Social Law Book XI (SBG XI) can take advantage of care counseling according to §7a SGB XI. To date, there is no systematic overview of counseling services for people with dementia and their relatives related to this specific provision in Germany.

METHODS

We conducted a gray-shaded scoping review with a focus on the evaluation of care counseling according to §7a SGB XI for people with dementia and their relatives. For this purpose, we applied five search strategies. We researched (1) national electronic databases, (2) Google, (3) targeted websites, (4) experts, and (5) academic electronic databases. Additionally, for the included gray literature, we conducted backward citation tracking via reference lists and forward citation tracking via Google Scholar for scientific articles. Screening of the identified potentially relevant records was performed independently by two reviewers.

RESULTS

We identified 985 records and included 6 studies in our review. We divided the identified studies into three themes: understanding conceptual dimensions, digitalization of counseling, and understanding the perspective of those being counseled. No studies investigated the perspective and experience of people with dementia and their relatives regarding the counseling service according to §7a SGB XI.

CONCLUSIONS

Our results show that further research is needed, especially regarding the experience of people with dementia and their relatives who participated in counseling according to §7a SGB XI. It seems essential to understand the perspective of people with dementia and their relatives to improve and tailor counseling services in Germany.

The review protocol was prospectively published (BMJ Open 12:e059771, 2022).

2023 Alzheimer's disease facts and figures

This article describes the public health impact of Alzheimer's disease, including prevalence and incidence, mortality and morbidity, use and costs of care, and the overall impact on family caregivers, the dementia workforce and society. The Special Report examines the patient journey from awareness of cognitive changes to potential treatment with drugs that change the underlying biology of Alzheimer's. An estimated 6.7 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060 barring the development of medical breakthroughs to prevent, slow or cure AD. Official death certificates recorded 121,499 deaths from AD in 2019, and Alzheimer's disease was officially listed as the sixth-leading cause of death in the United States. In 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death, Alzheimer's was the seventh-leading cause of death. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2019, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 145%. This trajectory of deaths from AD was likely exacerbated by the COVID-19 pandemic in 2020 and 2021. More than 11 million family members and other unpaid caregivers provided an estimated 18 billion hours of care to people with Alzheimer's or other dementias in 2022. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $339.5 billion in 2022. Its costs, however, extend to family caregivers' increased risk for emotional distress and negative mental and physical health outcomes - costs that have been aggravated by COVID-19. Members of the paid health care workforce are involved in diagnosing, treating and caring for people with dementia. In recent years, however, a shortage of such workers has developed in the United States. This shortage - brought about, in part, by COVID-19 - has occurred at a time when more members of the dementia care workforce are needed. Therefore, programs will be needed to attract workers and better train health care teams. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2023 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $345 billion. The Special Report examines whether there will be sufficient numbers of physician specialists to provide Alzheimer's care and treatment now that two drugs are available that change the underlying biology of Alzheimer's disease.
