End-of-life decision making by family caregivers of persons with advanced dementia: A literature review of decision aids

Supporting decision-making for individuals living with dementia and their care partners with knowledge translation: an umbrella review

Living with dementia requires decision-making about numerous topics including daily activities, such as advance care planning (ACP). Both individuals living with dementia and care partners require informed support for decision-making. We conducted an umbrella review to assess knowledge translation (KT) interventions supporting decision-making for individuals living with dementia and their informal care partners. Four databases were searched using 50 different search-terms, identifying 22 reviews presenting 32 KT interventions. The most common KT decision topic was ACP (N=21) which includes advanced care directives, feeding options, and placement in long-term care. The majority of KT interventions targeted care partners only (N=16), or both care partners and individuals living with dementia (N=13), with fewer interventions (N=3) targeting individuals living with dementia. Overall, our umbrella review offers insights into the beneficial impacts of KT interventions, such as increased knowledge and confidence, and decreased decisional conflicts.

A scoping review of decision-making tools to support substitute decision-makers for adults with impaired capacity

BACKGROUND

Substitute decision-makers (SDMs) make decisions that honor medical, personal, and end-of-life wishes for older adults who have lost capacity, including those with dementia. However, SDMs often lack support, information, and problem-solving tools required to make decisions and can suffer with negative emotional, relationship, and financial impacts. The need for adaptable supports has been identified in prior meta-analyses. This scoping review identifies evidence-based decision-making resources/tools for SDMs, outlines domains of support, and determines resource/tool effectiveness and/or efficacy.

METHODS

The scoping review used the search strategy: Population-SDMs for older adults who have lost decision-making capacity; Concept-supports, resources, tools, and interventions; Context-any context where a decision is made on behalf of an adult (>25 years). Databases included MEDLINE, Embase, CINAHL, PsycINFO, and Abstracts in Social Gerontology and SocIndex. Tools were scored by members on the research team, including patient partners, based on domains of need previously identified in prior meta-analyses.

RESULTS

Two reviewers independently screened 5279 citations. Articles included studies that evaluated a resource/tool that helped a family/friend/caregiver SDMs outside of an ICU setting. 828 articles proceeded onto full-text screening, and 25 articles were included for data extraction. The seventeen tools identified focused on different time points/decisions in the dementia trajectory, and no single tool encompassed all the domains of caregiver decision-making needs.

CONCLUSION

Existing tools may not comprehensively support caregiver needs. However, combining tools into a toolkit and considering their application relevant to the caregiver's journey may start to address the gap in current supports.

Interprofessional collaboration in palliative dementia care

Interprofessional collaboration (IPC) is essential for high-quality palliative care (PC) for persons with dementia. The aim of this scoping review was to identify IPC approaches in palliative dementia care and explore the elements constituting these approaches. We performed a search in PubMed, CINAHL, and PsychINFO using the Joanna Briggs Institute Reviewers' manual and PRISMA guidelines, and conducted content analysis of the included articles. In total, 28 articles were included, which described 16 IPC approaches in palliative dementia care. The content analysis revealed three overall elements of these approaches: 1) collaborative themes, 2) collaborative processes, and 3) resources facilitating collaboration. Frequently reported collaborative themes embraced pain management and providing care in the dying phase. These themes were addressed through intertwined collaborative processes including communication, coordination, assessing and monitoring, and reflecting and evaluating. To ensure optimal IPC in palliative dementia care, various resources were required, such as PC knowledge, skills to manage symptoms, skills to communicate with collaborators, and a facilitating environment. In conclusion, the identified IPC approaches in palliative dementia care involve diverse collaborating professionals who mainly manage symptoms, prepare for the dying phase and require material and immaterial resources to enable optimal IPC in palliative dementia care.

Resources to Support Decision-Making Regarding End-of-Life Nutrition Care in Long-Term Care: A Scoping Review

Resources are needed to aid healthcare providers and families in making end-of-life nutrition care decisions for residents living in long-term care settings. This scoping review aimed to explore what is reported in the literature about resources to support decision-making at the end of life in long-term care. Four databases were searched for research published from 2003 to June 2023. Articles included peer-reviewed human studies published in the English language that reported resources to support decision-making about end-of-life nutrition in long-term care settings. In total, 15 articles were included. Thematic analysis of the articles generated five themes: conversations about care, evidence-based decision-making, a need for multidisciplinary perspectives, honouring residents' goals of care, and cultural considerations for adapting resources. Multidisciplinary care teams supporting residents and their families during the end of life can benefit from resources to support discussion and facilitate decision-making.

The impact of the mySupport advance care planning intervention on family caregivers' perceptions of decision-making and care for nursing home residents with dementia: pretest-posttest study in six countries

BACKGROUND

the mySupport advance care planning intervention was originally developed and evaluated in Northern Ireland (UK). Family caregivers of nursing home residents with dementia received an educational booklet and a family care conference with a trained facilitator to discuss their relative's future care.

OBJECTIVES

to investigate whether upscaling the intervention adapted to local context and complemented by a question prompt list impacts family caregivers' uncertainty in decision-making and their satisfaction with care across six countries. Second, to investigate whether mySupport affects residents' hospitalisations and documented advance decisions.

DESIGN

a pretest-posttest design.

SETTING

in Canada, the Czech Republic, Ireland, Italy, the Netherlands and the UK, two nursing homes participated.

PARTICIPANTS

in total, 88 family caregivers completed baseline, intervention and follow-up assessments.

METHODS

family caregivers' scores on the Decisional Conflict Scale and Family Perceptions of Care Scale before and after the intervention were compared with linear mixed models. The number of documented advance decisions and residents' hospitalisations was obtained via chart review or reported by nursing home staff and compared between baseline and follow-up with McNemar tests.

RESULTS

family caregivers reported less decision-making uncertainty (-9.6, 95% confidence interval: -13.3, -6.0, P < 0.001) and more positive perceptions of care (+11.4, 95% confidence interval: 7.8, 15.0; P < 0.001) after the intervention. The number of advance decisions to refuse treatment was significantly higher after the intervention (21 vs 16); the number of other advance decisions or hospitalisations was unchanged.

CONCLUSIONS

the mySupport intervention may be impactful in countries beyond the original setting.

Nursing Home Resident, Family, and Staff Perspectives on Hospital Transfers for End-of-Life Care

Residents who are terminally ill often experience transfers to the emergency department resulting in hospitalizations, which may be potentially avoidable with treatment in the nursing home. This qualitative study explored the perspectives of 15 residents, 10 family members, and 20 nursing home staff regarding end-of-life care and the circumstances prompting resident transfers. Data analysis of participant interviews conducted January to May 2019 in a South Florida nursing home identified four themes related to transfer to the hospital: time left to live, when aggressive treatments would be unavailing, not knowing what the nursing home can do, and transfer decisions are situation-dependent. Study findings underscore the importance of increasing resident and family awareness of treatments available in the nursing home and person-centered advance care planning discussions. Further research should explore the reasons for residents' and family members' choice of aggressive therapies and their goals for care at the end of life.

Decision Aid Interventions for Family Caregivers of Persons With Advanced Dementia in Decision-Making About Feeding Options: A Scoping Review

OBJECTIVES

We provided an overview of the literature on decision aid interventions for family caregivers of older adults with advanced dementia regarding decision making about tube feeding. We synthesized (1) the use of theory during the development, implementation, and evaluation of decision aids; (2) the development, content, and delivery of decision aid interventions; (3) caregivers' experience with decision aid interventions; and (4) the effect of decision aid interventions on caregivers' quality of decision-making about feeding options.

DESIGN

Scoping review.

METHODS

We conducted a scoping review of peer-reviewed studies published January 1, 2000-June 30, 2022, in MEDLINE, EMBASE, The Cochrane Library, CINAHL, and Web of Science databases. The process was guided by Arksey and O'Malley's methodological framework, which includes identifying the research question, choosing related studies, charting the data, and summarizing results. Empirical articles concerning the decision aid interventions about feeding options were selected.

RESULTS

Six publications reporting 4 unique decision aid interventions were included. All the interventions targeted caregivers of older adults with advanced dementia. Three decision aids were culturally adapted from existing decision aids. The Ottawa Decision Support Framework and the International Patient Decision Aid Standards Framework were used in these 6 publications. Interventions aimed to improve decision making regarding tube feeding for caregivers through static delivery methods. Caregivers rated these decision aids as helpful and acceptable. Decisional conflict and knowledge of feeding options were the most common outcomes evaluated. Reduction in decisional conflict and increase in knowledge were consistently found among dementia caregivers, but no intervention effects were found on preferences for the use of tube feeding.

CONCLUSIONS AND IMPLICATIONS

Decision aid interventions effectively improve decision-making regarding tube feeding among the target population. Cultural adaptation of an existing decision aid intervention is the main strategy. However, the lack of guidance of a cultural adaptation framework in this process may lead to difficulties explaining caregivers' behavioral changes. Moreover, merely providing information is not enough to change caregivers' preferences or behavior of use of tube feeding. A systematic approach to cultural adaptation and interactive intervention is needed in future studies.

Decision-Support Needs of Caregivers Considering Hospice Enrollment for a Family Member With Dementia

Background: There are few evidence-based interventions to support the growing number of family caregivers of persons living with advanced dementias (PWADs) in surrogate decision-making roles. This study identifies needs for decision support among family caregivers considering hospice enrollment for PWADs, in order to better inform efforts for decision support. Method: Individual and focus group interviews were conducted with caregivers (n = 13) and healthcare professionals (n = 14). Directed content analysis was used to identify and organize themes that emerged from interview transcripts. Results: Analysis revealed 2 themes concerning PWAD caregivers' hospice-related decision-support needs: (1) detailed and practical information about hospice and (2) discussions clarifying meaning around quality of life (QOL) for PWADs. Caregivers needed to know when they should consider hospice, what treatments would be stopped, what services would help caregivers, and what costs would be involved. Caregivers varied in their perceptions of what it might mean for a PWAD to have QOL at the end of life and whether or not hospice would enhance it. Discussion: This study's findings underscore the importance of decision-support tools and patient- and family-centered education for PWADs and caregivers about the trajectory of dementia and end-stage symptoms, along with practical information for hospice care planning and discussions addressing end of life values.

Support needs of carers making proxy healthcare decisions for people with dementia: a systematic review based on the Noblit and Hare meta-ethnographic synthesis of qualitative studies

BACKGROUND

There are 50 million dementia sufferers worldwide. Decisions about healthcare often need to be made when the person with dementia lacks capacity to do so.Understanding the support needs of carers acting as proxy healthcare decision-makers will be vital in improving the decision-making process for people with dementia and addressing the holistic needs of carers.

OBJECTIVE

The objective of this study was to review the existing literature on the support needs of carers acting as proxy healthcare decision-makers for people with dementia.

DESIGN

A qualitative systematic review protocol was published on PROSPERO. The Critical Appraisal Skills Programme checklist was used to appraise study quality. A meta-ethnographic synthesis was performed to develop third-order constructs.

DATA SOURCES

A search was conducted using three online databases (MEDLINE, CINAHL and PsycINFO).

ELIGIBILITY CRITERIA

Fifteen studies met the inclusion criteria: primary qualitative research involving carers of people with dementia who had been involved in making proxy healthcare decisions.

DATA EXTRACTION AND SYNTHESIS

Two independent researchers conducted validity assessments for each paper selected for inclusion, and discrepancies were resolved by discussions with a third reviewer. Nvivo software was used and conceptual findings from study papers lead to interpretations of findings by the team.

RESULTS

From the 15 papers included in the study, three main domains arose from the meta-ethnography; informational, practical and emotional. Informational support needs included information about dementia itself and the anticipated disease trajectory. Practical needs included continuity of care, person-centred care and the use of legal frameworks.Emotional support included recognising the guilt that healthcare decisions can provoke and the importance of providing guidance in an empathic manner.

CONCLUSIONS

This meta-ethnography highlights opportunities for healthcare professionals and policymakers to improve experiences of carers making proxy healthcare decisions for people with dementia.

Caregiving for Patients With Frontotemporal Dementia in Latin America

Latin America is a vast heterogeneous territory where chronic diseases such as mild cognitive impairment or dementia are becoming higher. Frontotemporal dementia (FTD) prevalence in this region is estimated to be around 12-18 cases per thousand persons. However, this prevalence is underestimated given the lack of awareness of FTD even among healthcare professionals. Family members are responsible for the care of patients with FTD at home. These caregivers deliver care despite being ill-equipped and living in the context of austerity policies and social inequities. They often face unsurmountable financial and social burdens that are specific to the region. The most important step to support caregivers in Latin America is to increase awareness of the disease at all levels. Healthcare diplomacy is fundamental to create joint efforts that push policies forward to protect caregivers of FTD patients.

The Impact of Dementia on Cancer Treatment Decision-Making, Cancer Treatment, and Mortality: A Mixed Studies Review

Dementia and cancer occur commonly in older adults. Yet, little is known about the effect of dementia on cancer treatment and outcomes in patients diagnosed with cancer, and no guidelines exist. We performed a mixed studies review to assess the current knowledge and gaps on the impact of dementia on cancer treatment decision-making, cancer treatment, and mortality. A search in PubMed, Medline, and PsycINFO identified 55 studies on older adults with a dementia diagnosis before a cancer diagnosis and/or comorbid cancer and dementia published in English from January 2004 to February 2020. We described variability using range in quantitative estimates, ie, odds ratios (ORs), hazard ratios (HRs), and risk ratios (RR) when appropriate and performed narrative review of qualitative data. Patients with dementia were more likely to receive no curative treatment (including hospice or palliative care) (OR, HR, and RR range = 0.40-4.4, n = 8), while less likely to receive chemotherapy (OR and HR range = 0.11-0.68, n = 8), radiation (OR range = 0.24-0.56, n = 2), and surgery (OR range = 0.30-1.3, n = 4). Older adults with cancer and dementia had higher mortality than those with cancer alone (HR and OR range = 0.92-5.8, n = 33). Summarized findings from qualitative studies consistently revealed that clinicians, caregivers, and patients tended to prefer less aggressive care and gave higher priority to quality of life over life expectancy for those with dementia. Current practices in treatment-decision making for patients with both cancer and dementia are inconsistent. There is an urgent need for treatment guidelines for this growing patient population that considers patient and caregiver perspectives.

Rapid review of decision-making for place of care and death in older people: lessons for COVID-19

Introduction

The coronavirus pandemic (COVID-19) has affected the functioning and capacity of healthcare systems worldwide. COVID-19 has also disproportionately affected older adults. In the context of COVID-19, decision-making surrounding place of care (PoC) and place of death (PoD) in older adults involves significant new challenges.

Aims

To explore key factors that influence PoC and PoD decisions in older adults. A secondary aim was to investigate key factors that influence the process and outcome of these decisions in older adults. To apply findings from current evidence to the context of COVID-19.

Methods

Rapid review of reviews, undertaken using WHO guidance for rapid reviews for the production of actionable evidence. Data extracted was synthesised using narrative synthesis, with thematic analysis and tabulation.

Results

10 papers were included for full data extraction. These papers were published between 2005 and 2020. Papers included discussed actual PoD, as well as preferred. Results were divided into papers that explored the process of decision-making, and those that explored decision-making outcomes.

Conclusions

The process and outcomes of decision-making for older people are affected by many factors—all of which have the potential to influence both patients and caregivers experience of illness and dying. Within the context of COVID-19, such decisions may have to be made rapidly and be reflexive to changing needs of systems and of families and patients.

Enhancing shared and surrogate decision making for people living with dementia: A systematic review of the effectiveness of interventions

BACKGROUND

Dementia can have a profound impact on decision making. People living with dementia (PLwD) often need to make decisions about health care, and, as dementia progresses, decisions may need to be made on their behalf. Specific interventions may support this process.

REVIEW QUESTION

What interventions are effective in improving shared decision making or surrogate decision making on the health care of PLwD?

METHODS

A narrative systematic review of existing literature was conducted. Seven databases, grey literature and key journals were searched. After exclusion by title, abstracts then full texts were reviewed collaboratively to manage any disagreements.

RESULTS

Eight studies met the inclusion criteria. Two articles, including one RCT, evaluated decision aids regarding the use of enteral feeding in advanced dementia. Six further articles, including five RCTs, were found which evaluated the effectiveness of interventions supporting patients or carers with advance care planning.

CONCLUSION

Decision-making interventions typically consist of multiple components which aim to establish preferences for future health care. Advance care planning interventions supported aspects of the decision-making processes but their impact on decision quality was rarely evaluated. Interventions did not increase the concordance of decisions with a person's values. The decision-specific interventions are unlikely to produce benefit in other decision contexts.

PATIENT INVOLVEMENT

Two caregivers, a public stakeholder group and a carer group were consulted in the design of the wider study to which this review relates. Six PLwD refined the research questions addressed in this paper.

Palliative and end-of-life care for people living with dementia in rural areas: A scoping review

Background and objectives

People living with dementia deserve to experience the benefits of receiving palliative care and end-of-life services and supports, yet they often do not receive this care compared to those with other terminal diseases. People living with dementia in rural areas often face additional challenges to accessing such care. The purpose of this scoping review was to systematically review and synthesize the literature on palliative and end-of-life care for people with dementia living in rural areas, and to identify and describe key findings and gaps in the literature.

Methods

A collaborative research team approach was used in an iterative process across all stages of this review. Systematic, comprehensive searches were conducted across ten databases and eight targeted websites for relevant peer-reviewed, original research and other less formal literature, published in English, which yielded a total of 4476 results. After duplicate removal, screening, and review, 24 items were included for synthesis.

Results

All items were described and illustrated by frequency distribution, findings were grouped thematically, and five key themes emerged, including: 1) Knowledge about dementia, 2) Availability, accessibility, and utilization of palliative and end-of-life care services and supports, 3) Decision-making about care, the value of a person-centered approach and collaborative support, 4) Perspectives on artificial nutrition, hydration, and comfort care, and 5) Quality of life and death. The main gap identified was literature pertaining to rural populations, especially from locations other than the United States. The influence of rurality on relevant findings was mixed across rural-urban comparison studies, as was the effect of sex and gender across the literature.

Conclusions

Several areas were highlighted including the importance of increasing knowledge about dementia, having early conversations about advanced care and treatment options, providing a person-centered approach, and the potential for using technology to address rural access issues. These findings can be used to inform future research and policy and the development of services, supports, and strategies for rural people living with dementia. Further research is recommended.

"Imagine You Have ALS": Death Education to Prepare for Advance Treatment Directives

The study presents the results of qualitative research carried out within a death education project dedicated to advance treatment directives (ATDs) in which it was proposed to participants to empathize with people who had received a diagnosis of Amyotrophic Lateral Sclerosis (ALS). The study involved 104 people who discussed and reflected on issues related to the knowledge of having to die, palliative care and ATDs, investigating what choices they would have made if they had received such a diagnosis. Finally, they were asked to write a paper describing their impressions and hypothetical choices. Qualitative analysis has elucidated among fundamental themes. Four thematic areas emerged from the data analysis: (1) ATDs and the family; (2) the importance of reducing pain and suffering; (3) emotions and considerations regarding death, illness and spirituality; and (4) opinions on the DeEd course. It has emerged that some people are unfamiliar with palliative care or the right to self-determination and that addressing these issues helps manage the thought of the future with less terror. The experience of death education has therefore proven to be very positive in dealing with complex and often censored issues, allowing thinking about death in a less distressing way.

Artificial Intelligence for Caregivers of Persons With Alzheimer's Disease and Related Dementias: Systematic Literature Review

BACKGROUND

Artificial intelligence (AI) has great potential for improving the care of persons with Alzheimer's disease and related dementias (ADRD) and the quality of life of their family caregivers. To date, however, systematic review of the literature on the impact of AI on ADRD management has been lacking.

OBJECTIVE

This paper aims to (1) identify and examine literature on AI that provides information to facilitate ADRD management by caregivers of individuals diagnosed with ADRD and (2) identify gaps in the literature that suggest future directions for research.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for conducting systematic literature reviews, during August and September 2019, we performed 3 rounds of selection. First, we searched predetermined keywords in PubMed, Cumulative Index to Nursing and Allied Health Literature Plus with Full Text, PsycINFO, IEEE Xplore Digital Library, and the ACM Digital Library. This step generated 113 nonduplicate results. Next, we screened the titles and abstracts of the 113 papers according to inclusion and exclusion criteria, after which 52 papers were excluded and 61 remained. Finally, we screened the full text of the remaining papers to ensure that they met the inclusion or exclusion criteria; 31 papers were excluded, leaving a final sample of 30 papers for analysis.

RESULTS

Of the 30 papers, 20 reported studies that focused on using AI to assist in activities of daily living. A limited number of specific daily activities were targeted. The studies' aims suggested three major purposes: (1) to test the feasibility, usability, or perceptions of prototype AI technology; (2) to generate preliminary data on the technology's performance (primarily accuracy in detecting target events, such as falls); and (3) to understand user needs and preferences for the design and functionality of to-be-developed technology. The majority of the studies were qualitative, with interviews, focus groups, and observation being their most common methods. Cross-sectional surveys were also common, but with small convenience samples. Sample sizes ranged from 6 to 106, with the vast majority on the low end. The majority of the studies were descriptive, exploratory, and lacking theoretical guidance. Many studies reported positive outcomes in favor of their AI technology's feasibility and satisfaction; some studies reported mixed results on these measures. Performance of the technology varied widely across tasks.

CONCLUSIONS

These findings call for more systematic designs and evaluations of the feasibility and efficacy of AI-based interventions for caregivers of people with ADRD. These gaps in the research would be best addressed through interdisciplinary collaboration, incorporating complementary expertise from the health sciences and computer science/engineering-related fields.

Mobile Health, Information Preferences, and Surrogate Decision-Making Preferences of Family Caregivers of People With Dementia in Rural Hispanic Communities: Cross-Sectional Questionnaire Study

BACKGROUND

Mobile health (mHealth) technology holds promise for promoting health education and reducing health disparities and inequalities in underserved populations. However, little research has been done to develop mHealth interventions for family caregivers of people with dementia, particularly those in rural Hispanic communities, who often serve as surrogate decision makers for their relatives with dementia.

OBJECTIVE

As part of a larger project to develop and test a novel, affordable, and easy-to-use mHealth intervention to deliver individually tailored materials in rural Hispanic communities, in this pilot study, we aimed to examine (1) characteristics of people with dementia and their family caregivers in rural Hispanic communities, (2) caregivers' preferences for types and amounts of health information and participation in surrogate decision making, and (3) caregivers' mobile device usage and their desire for receiving information via mobile devices.

METHODS

This was a cross-sectional survey. A convenience sample of 50 caregivers of people with dementia was recruited from rural health care facilities in Southwest Texas during 3 weeks of April 2017 to May 2017 via word-of-mouth and flyers posted at the facilities.

RESULTS

More women than men were in the patient group (χ21=17.2, P<.001) and in the caregiver group (χ21=22.2, P<.001). More patients were on Medicare and Medicaid; more caregivers had private insurance (P<.001 in all cases). Overall, 42% of patients did not have a power of attorney for their health care; 40% did not have a living will or advance directive. Caregivers were interested in receiving all types of information and participating in all types of decisions, although on subscales for diagnosis, treatment, laboratory tests, self-care, and complementary and alternative medicine, their levels of interest for decision-making participation were significantly lower than those for receiving information. On the psychosocial subscale, caregivers' desire was greater for surrogate decision-making participation than for information. Caregivers did not differ in their interests in information and participation in decision making on the health care provider subscale. All but 1 caregiver (98%) owned a mobile phone and 84% had a smartphone. Two-thirds wanted to receive at least a little dementia-related information via a smartphone or tablet. The amount of dementia-related information caregivers wanted to receive via a mobile device was significantly greater for women than for men (U=84.50, P=.029). Caregivers who owned a tablet were more likely to want to receive dementia-related information via a mobile device than those who did not own a tablet (U=152.0, P=.006).

CONCLUSIONS

Caregivers in rural Hispanic communities were interested in receiving a wide range of information as well as participating in making decisions for their relatives with dementia. There is much need for effective mHealth interventions that can provide information tailored to the needs and preferences of these caregivers.
