Palliative care in dementia: issues and evidence

Mortality and its predictors among people with dementia receiving psychiatric in-patient care

BACKGROUND

Although dementia is a terminal condition, palliation can be a challenge for clinical services. As dementia progresses, people frequently develop behavioural and psychological symptoms, sometimes so severe they require care in specialist dementia mental health wards. Although these are often a marker of late disease, there has been little research on the mortality of people admitted to these wards.

AIMS

We sought to describe the mortality of this group, both on-ward and after discharge, and to investigate clinical features predicting 1-year mortality.

METHOD

First, we conducted a retrospective analysis of 576 people with dementia admitted to the Cambridgeshire and Peterborough National Health Service (NHS) Foundation Trust dementia wards over an 8-year period. We attempted to identify predictors of mortality and build predictive machine learning models. To investigate deaths occurring during admission, we conducted a second analysis as a retrospective service evaluation involving mental health wards for people with dementia at four NHS trusts, including 1976 admissions over 7 years.

RESULTS

Survival following admission showed high variability, with a median of 1201 days (3.3 years). We were not able to accurately predict those at high risk of death from clinical data. We found that on-ward mortality remains rare but had increased from 3 deaths per year in 2013 to 13 in 2019.

CONCLUSIONS

We suggest that arrangements to ensure effective palliation are available on all such wards. It is not clear where discussions around end-of-life care are best placed in the dementia pathway, but we suggest it should be considered at admission.

A Systematic Review of Palliative Care Needs in Young-Onset Dementia

BACKGROUND

The distinctive differences in clinical needs and disease trajectory between people with young-onset (YOD) and late-onset dementia (LOD) make dementia palliative care unique. Limited studies have reported on the differences in palliative care needs between YOD and LOD, and the optimal time point to introduce palliative care in YOD remains controversial. We performed a systematic review to summarize key issues surrounding palliative care in YOD and highlight unmet needs in this pertinent area.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched the PubMed database for all studies published between January 2000 and July 2022 that reported on palliative care in YOD.

RESULTS

Of 32 records identified, 8 articles were eligible for inclusion. The top 3 themes extracted centered around (1) clinical differences between YOD and LOD, (2) symptoms and causes of death in end-stage YOD, and (3) the importance of early advanced care planning (ACP). YOD diagnosis is often delayed and people with YOD have fewer somatic comorbidities but more neuropsychiatric symptoms, longer survival times, and a more malignant disease course. People with YOD and their families face unique psychosocial challenges when symptoms start at a younger age. End-stage YOD is not dissimilar to LOD where patients suffer from a broad spectrum of physical and psychological symptoms requiring palliation. Early initiation of ACP discussion is crucial in YOD given the more rapid progression of disease affecting cognition and decision-making capacity; however, rates of ACP completion in YOD remain low.

CONCLUSIONS

Given the complex care needs and more rapid disease trajectory in YOD, palliative care in YOD should be considered from the time of diagnosis, and to be incorporated into routine dementia care.

Developing a best-practice agenda for music therapy research to support informal carers of terminally ill patients pre- and post-death bereavement: a world café approach

BACKGROUND

Informal carers of terminally ill patients play a vital role in providing palliative care at home, which impacts on their pre- and post-death bereavement experience and presents an up to 50% greater risk for mental-health problems. However, developing and implementing effective bereavement support remains challenging. There is a need to build the evidence base for music therapy as a potentially promising bereavement support for this vulnerable population. This study aimed to co-design an international best practice agenda for research into music therapy for informal carers of patients pre- and post-death bereavement.

METHODS

Online half day workshop using a World Café approach; an innovative method for harnessing group intelligence within a group of international expert stakeholders (music therapy clinicians and academics with experience of music therapy with informal carers at end-of-life). Demographics, experience, key priorities and methodological challenges were gathered during a pre-workshop survey to inform workshop discussions. The online workshop involved four rounds of rotating, 25-minute, small group parallel discussions using Padlet. One final large group discussion involved a consensus building activity. All data were analysed thematically to identify patterns to inform priorities and recommendations.

RESULTS

Twenty-two consented and completed the pre-event survey (response rate 44%), from countries representing 10 different time zones. Sixteen participated in the workshop and developed the following best practice agenda. The effectiveness of music therapy in supporting informal carers across the bereavement continuum should be prioritised. This should be done using a mixed methods design to draw on the strengths of different methodological approaches to building the evidence base. It should involve service users throughout and should use a core outcome set to guide the choice of clinically important bereavement outcome measures in efficacy/effectiveness research.

CONCLUSIONS

Findings should inform future pre- and post-death bereavement support research for informal caregivers of terminally ill patients. This is an important step in building the evidence base for commissioners and service providers on how to incorporate more innovative approaches in palliative care bereavement services.

Dementia in People with Severe/Profound Intellectual (And Multiple) Disabilities, and Its Natural History

Introduction

Although the prevalence of dementia increases among people with severe/profound intellectual (and multiple) disabilities (SPI(M)D), dementia in people with SPI(M)D is not yet fully understood. Therefore, this study aimed to characterize the natural history of dementia in people with SPI(M)D, in particular, the prevalence and time of onset of dementia symptoms.

Methods

An explorative retrospective review of clinical records was conducted for people with SPI(M)D without dementia (n = 103), with questionable dementia (n = 19), and with diagnosed dementia (n = 19). Presence and time of onset of symptoms were extracted and compared between groups.

Results

People with questionable dementia or diagnosed dementia had compared to people without dementia more symptoms regarding the cognitive, activities of daily living, behavioral/psychological, and motor domains. The most prevalent early symptoms were memory loss, declined walking skills, increased anxious, apathetic, and irritable behavior. Predictors for dementia were the number of cognitive, behavioral/psychological, and motor symptoms.

Conclusion

These results contribute to enhance our understanding of dementia in people with SPI(M)D, which is essential for earlier recognizing and diagnosing dementia.

The "Counseling+" Roles of the Speech-Language Pathologist Serving Older Adults With Mild Cognitive Impairment and Dementia From Alzheimer's Disease

Purpose

Persons with dementia and mild cognitive impairment (MCI) are major consumers of services provided by speech-language pathologists (SLPs). These services include not only direct assessment and treatment of communication and swallowing but also counseling, collaboration, prevention, and wellness. These "counseling+" activities can be especially challenging for SLPs to deliver because of the lack of evidence, as well as the complex nature of Alzheimer's disease (AD) and other conditions that cause MCI and dementia.

Method

This tutorial is written by a speech-language pathologist, a neuropsychologist, and a geriatric psychiatrist to provide education, resources, and recommendations for SLPs delivering counseling+ activities to patients with MCI and dementia from AD and related disorders.

Results and Conclusions

We describe counseling+ activities across the continuum of care ranging from educating and conducting cognitive screenings with adults experiencing age-related cognitive decline to supporting end-of-life wishes. Because of their expertise in communication, SLPs can provide an array of important leading and supporting services to patients, their family, and other health care professionals on the care team, such as providing patients with appropriate feedback following a cognitive screening and helping caregivers identify the communicative intent of a responsive behavior. The demand for SLP services for patients with MCI and dementia will grow significantly over the next few decades, necessitating more systematic research and clinical evidence in this area.

Doença de Alzheimer: a experiência única de cuidadores familiares

Resumo A demência é uma síndrome de curso lento, progressivo e de natureza crônica, sendo o subtipo doença de Alzheimer (DA) a mais comum. Muitos estudos são realizados a partir das demandas da pessoa com demência, porém na perspectiva do cuidador eles são escassos. A pesquisa qualitativa teve como objetivo conhecer aspectos singulares da experiência do cuidar na perspectiva de cuidadoras familiares de idosos com DA, a partir de abordagem qualitativa. Foi utilizado o método fenomenológico proposto por Giorgi e Sousa. Participaram nove cuidadoras familiares (quatro esposas e cinco filhas) que cuidam de seus familiares. Esta pesquisa acompanhou o cuidar na fase inicial, moderada, avançada, em diferentes estágios da doença e no pós-óbito. A partir da questão central: “Como é para você a experiência de acompanhar seu familiar com a doença de Alzheimer?”, emergiram treze unidades temáticas que foram associadas às fases da doença. Os resultados apontaram as necessidades dos cuidadores, que vão desde o diagnóstico em fases iniciais até a criação de espaço para escuta e acolhimento diante das perdas graduais vivenciadas ao longo do processo de cuidar. Assim, é urgente o investimento em formação de profissionais em todas as áreas envolvidas no cuidar para promover qualidade de vida e bem-estar aos cuidadores. bem como a necessidade de equipes interdisciplinares para a experiência singular do cuidado em demência.

Chronic Palliative Care: Specific Practices for Alzheimer's Disease Sufferers

Introduction: In France, the government's plan to combat Alzheimer's disease takes into consideration mostly the beginnings of the disease; it does not deal with the sufferers’ end of life. For this pathology, the very idea of a palliative care phase and its definition are not straightforward. Method: The object of this qualitative study was to clarify this idea through a series of interviews with 44 professionals. Results: The study describes three successive phases in the disease trajectory, revealed by changes in the logic of care: the stimulation phase, the chronic palliative care phase, and the terminal palliative phase. Conclusion: Alzheimer's disease has a specific phase of chronic palliative care. It presents, for professionals, several types of problems related to communication, pain, and feeding.

Acceptability of Paper-Based Advance Care Planning (ACP) to Inform End-of-Life Care Provision for Community Dwelling Older Adults: A Qualitative Interview Study

This paper reports the findings from a study to investigate health care professionals’ views regarding the use and acceptability of two similar paper-based advance care planning (ACP) documents designed for older adults in their last year of life to inform end-of-life care provision. Participants’ views of using PEACE (Proactive Elderly Persons Advisory Care), a nurse led model with community geriatrician oversight, and PACe (proactive anticipatory care plan), a general practitioner (GP) led model implemented by two clinical commissioning groups (CCGs) as part of a wider pilot to determine their ability to improve end-of-life care provision, were explored. Hospital admission avoidance matrons took part in face to face interviews and care staff employed in private residential care homes took part in individual telephone interviews to explore their views of using the PEACE tool. Telephone interviews were conducted with GPs to explore their views of PACe. GPs and admission avoidance matrons were employed by CCGs and all study participants were recruited from the South East of England, where data collection took place in 2015. The data were analysed thematically. Findings from the study demonstrate how both tools provide a focus to ACP discussions to inform individual end-of-life care preferences. The importance of relationships was a pivotal theme established, trusting inter-professional relationships to enable multidisciplinary teamwork and a prior relationship with the older person (or their proxy in the case of cognitive impairment) to enable such conversations in the first place. Both tools enabled participants to think critically and reflect on their own practice. Notwithstanding participants’ views to improve their layout, using a paper-based approach to deliver streamlined ACP and end-of-life care was a theme to emerge as a potential barrier, and highlighted problems with accessing paper-based documentation, accuracy and care co-ordination in the context of multidisciplinary team working. The value of technology in overcoming this barrier and underpinning ACP as a means to help simplify service provision, promote integrated professional practice and provide seamless care, was put forward as a way forward.

Meaningful connections in dementia end of life care in long term care homes

BACKGROUND

Most persons with dementia die in long term care (LTC) homes, where palliative approaches are appropriate. However, palliative approaches have not been widely implemented and there is limited understanding of staff and family experiences of dying and bereavement in this context.

METHOD

This descriptive qualitative study explored family and staff experiences of end of life and end of life care for persons with dementia in LTC homes. Eighteen focus groups were conducted with 77 staff members and 19 relatives of persons with dementia at four LTC homes in four Canadian provinces.

RESULTS

Three themes emerged: knowing the resident, the understanding that they are all human beings, and the long slow decline and death of residents with dementia.

DISCUSSION

Intimate knowledge of the person with dementia, obtained through longstanding relationships, was foundational for person-centred end of life care. Health care aides need to be included in end of life care planning to take advantage of their knowledge of residents with dementia. There were unmet bereavement support needs among staff, particularly health care aides. Persons with dementia were affected by death around them and existing rituals for marking deaths in LTC homes may not fit their needs. Staff were uncomfortable answering relatives' questions about end of life.

CONCLUSIONS

Longstanding intimate relationships enhanced end of life care but left health care aides with unmet bereavement support needs. Staff in LTC homes should be supported to answer questions about the trajectory of decline of dementia and death. Further research about residents' experiences of deaths of other residents is needed.

How is palliative care understood in the context of dementia? Results from a massive open online course

BACKGROUND

A palliative approach to the care of people with dementia has been advocated, albeit from an emergent evidence base. The person-centred philosophy of palliative care resonates with the often lengthy trajectory and heavy symptom burden of this terminal condition.

AIM

To explore participants' understanding of the concept of palliative care in the context of dementia. The participant population took an online course in dementia.

DESIGN

The participant population took a massive open online course on 'Understanding Dementia' and posted answers to the question: 'palliative care means …' We extracted these postings and analysed them via the dual methods of topic modelling analysis and thematic analysis.

SETTING/PARTICIPANTS

A total of 1330 participants from three recent iterations of the Understanding Dementia Massive Open Online Course consented to their posts being used. Participants included those caring formally or informally for someone living with dementia as well as those with a general interest in dementia Results: Participants were found to have a general awareness of palliative care, but saw it primarily as terminal care, focused around the event of death and specialist in nature. Comfort was equated with pain management only. Respondents rarely overtly linked palliative care to dementia.

CONCLUSIONS

A general lack of palliative care literacy, particularly with respect to dementia, was demonstrated by participants. Implications for dementia care consumers seeking palliative care and support include recognition of the likely lack of awareness of the relevance of palliative care to dementia. Future research could access online participants more directly about their understandings/experiences of the relationship between palliative care and dementia.

Knowledge of Dementia Among the Australian Health Workforce: A National Online Survey

Dementia is a leading cause of death and disability in Australia. This research evaluated dementia knowledge and educational needs among the Australian health workforce. An online version of the validated Dementia Knowledge Assessment Scale (DKAS) was administered with a random sample of 234 health professionals across eight Australian states. Respondents provided additional self-report data concerning dementia experiences, educational needs, and demographic information. Dementia knowledge deficiencies were identified concerning risk factors, prevalent typologies of the condition, and cognitive symptoms. Prior university education and dementia-specific training were predictive of significantly higher knowledge scores. Self-reported dementia education needs included nonpharmaceutical interventions for the behavioral and psychological symptoms and best-evidence care provision. Knowledge deficiencies among health workers suggest patients with dementia may not be receiving consistent, best-evidence care in Australia. The research findings will support the development of a targeted online dementia education intervention that aims to improve health worker knowledge and patient care.

Pain Intervention for people with Dementia in nursing homes (PID): study protocol for a quasi-experimental nurse intervention

BACKGROUND

It is estimated that 19 to 83% of people with dementia suffer from pain that is inadequately treated in the last months of life. A large number of healthcare workers who care for these people in nursing homes lack appropriate expertise and may therefore not always recognise, assess and treat pain in those with dementia who have complex problems on time, properly and efficiently. The aim of this intervention trial is to identify care needs of people with dementia suffering from pain living in a nursing home.

METHODS

A quasi-experimental nurse-led intervention trial based on a convenience sample of four nursing homes in the Swiss Canton of Zurich examines the effects on dementia patients (n = 411), the healthcare institution and the qualification level of the healthcare workers compared to historical controls, using an event analysis and a multilevel analysis. Healthcare workers will be individually trained how to assess, intervene and evaluate acute and chronic pain. There are three data-monitoring cycles (T0, T1, T2) and two intervention cycles (I1, I2) with a total study duration of 425 days. There is also a process evaluation based on Dobbins analyses that analyse in particular the potentials for change in clinical practice of change agents.

DISCUSSION

The aim of the intervention trial is to improve pain management strategies in older people with dementia in nursing homes. Clinically significant findings will be expected that will help reduce suffering in the sense of "total pain" for people with dementia. The joint intra- and interdisciplinary collaboration between practice and supply-oriented (nursing) research will have both a lasting effect on the efficiency measurement and provide scientifically sound results. Nursing homes can integrate the findings from the intervention trial into their internal quality control process. The potential for improvements can be directly influenced by the nursing home itself.

Progressive compensatory symbiosis: spouse caregiver experiences of caring for persons with dementia in Taiwan

OBJECTIVES

Spouse caregivers have been the predominant family members who care for persons with dementia in Taiwan. Although studies in western countries have described the caregiving experiences and changes in the marital relationship for these spouse caregivers, this information is lacking in Taiwan. This study explored the experiences of spouse caregivers caring for persons with dementia in Taiwan.

METHODS

A grounded theory approach was used for this qualitative descriptive study. Data were collected through recorded in-depth interviews and observations with 15 spouse caregivers of persons with dementia. Constant comparative analysis was used to analyse the transcripts and field notes.

RESULTS

Analysis of interview transcripts revealed that the experiences of caregiving for spouse caregivers who lived with persons with dementia could be described as 'progressive compensatory symbiosis.' This core category included three components: awareness of unbalanced intimacy, making a commitment and implementing a compensatory scheme. These experiences could be either mutually beneficial or unbalanced and fluctuated as the disease progressed through the phases of 'subtle,' 'revealed' and 'confirmed,' which also influence the pace, transition and evolution of the compensatory symbiosis.

CONCLUSION

This exploratory study describes the family caregiving experiences for 15 spouse caregivers of persons with dementia in Taiwan. These results can provide guidance for developing interventions to prepare, facilitate and promote a mutually beneficial adjustment for spousal caregivers and their spouses as dementia progresses. The findings are worthy of further investigation with a larger sample and a prospective design.

Consensus views on advance care planning for dementia: a Delphi study

The uptake of advance care planning (ACP) is particularly low among people with dementia. This may reflect barriers to communication between professionals, patients and families in the face of lack of consensus about the process. This study aimed to methodically investigate consensus views of how ACP should be explained and carried out with people with dementia. A three-round Delphi study explored views of how and when ACP should be addressed, what should be covered, who should be involved and why rates of ACP are low. Seventeen participants took part comprising family members, old age psychiatrists and policy makers. Thirty-two items reached consensus. The panel agreed on 11 different areas for discussion. They concurred that ACP was best addressed after the person has come to terms with the diagnosis when the individual feels ready to do so. There was a consensus view that the process should be couched in terms of 'certain possibilities'. Consensus items emphasised personal choice and autonomy, while also prioritising the need to discuss financial aspects and to include spouses. There was no consensus that professionals should be involved, although the panel viewed them as carrying some responsibility for low uptake. It is suggested that ACP should include general discussion of values as well as coverage of specific points. Professionals need to offer discussion and information on ACP, but also make clear that the patient has the right to choose whether to pursue ACP or not.

First Do No Harm: Euthanasia of Patients with Dementia in Belgium

In Memory of Ed Pellegrino. Euthanasia in Belgium is not limited to terminally ill patients. It may be applied to patients with chronic degenerative diseases. Currently, people in Belgium wish to make it possible to euthanize incompetent patients who suffer from dementia. This article explains the Belgian law and then explores arguments for and against euthanasia of patients with dementia. It probes the dementia paradox by elucidating Dworkin's distinction between critical and experiential interests, arguing that at the end-of-life this distinction is not clearcut. It argues against euthanasia for patients with dementia, for respecting patients' humanity and for providing them with more care, compassion, and good doctoring.

End-of-life care in psychiatry: 'one chance to get it right'

End-of-life care has been given increasing importance within healthcare settings. In June 2014, the Leadership Alliance for the Care of Dying People published One Chance to Get it Right. This nationally accepted guidance replaces previous end-of-life care pathways such as the Liverpool Care Pathway and outlines how dying patients should be managed irrespective of setting. Increasingly, patients with mental health problems are entering their final days of life within psychiatric in-patient or acute hospital settings, and psychiatrists need to be aware of the new guidance and ready to implement it within psychiatric practice.

Symptom Assessment for a Palliative Care Approach in People With Dementia Admitted to Acute Hospitals: Results From a National Audit

CONTEXT

As the prevalence of dementia increases, more people will need dementia palliative and end-of-life (EOL) care in acute hospitals. Published literature suggests that good quality care is not always provided.

OBJECTIVE

To evaluate the prescription of antipsychotics and performance of multidisciplinary assessments relevant to palliative care for people with dementia, including those at EOL, during hospital admission.

METHOD

As part of a national audit of dementia care, 660 case notes were reviewed across 35 acute hospitals.

RESULTS

In the entire cohort, many assessments essential to dementia palliative care were not performed. Of the total sample, 76 patients died, were documented to be receiving EOL care, and/or were referred for specialist palliative care. In this cohort, even less symptom assessment was performed (eg, no pain assessment in 27%, no delirium screening in 68%, and no mood or behavioral and psychological symptoms of dementia in 93%). In all, 37% had antipsychotic drugs during their admission and 71% of these received a new prescription in hospital, most commonly for "agitation."

CONCLUSION

This study suggests a picture of poor symptom assessment and possible inappropriate prescription of antipsychotic medication, including at EOL, hindering the planning and delivery of effective dementia palliative care in acute hospitals.

The basis, ethics and provision of palliative care for dementia: A review

Interest in palliative care for people with dementia has been around for over two decades. There are clinical and ethical challenges and practical problems around the implementation of good quality palliative care in dementia. This narrative review of the literature focuses on the rationale or basis for services, some of the ethical issues that arise (particularly to do with artificial nutrition and hydration) and on the provision and implementation of services. We focus on the most recent literature. The rationale for palliative care for people with dementia is based on research and on an identified need for better clinical care. But the research largely demonstrates a paucity of good quality evidence, albeit particular interventions (and non-interventions) can be justified in certain circumstances. Numerous specific clinical challenges in end-of-life care for people with dementia are ethical in nature. We focus on literature around artificial nutrition and hydration and conclude that good communication, attention to the evidence and keeping the well-being of the person with dementia firmly in mind will guide ethical decision-making. Numerous challenges surround the provision of palliative care for people with dementia. Palliative care in dementia has been given definition, but can still be contested. Different professionals provide services in different locations. More research and education are required. No single service can provide palliative care for people with dementia.

Knowledge of Dementia: Do family members understand dementia as a terminal condition?

Current research identifies advanced dementia to be the terminal phase of this progressive and incurable condition. However, there has been relatively little investigation into how family members of people with advanced dementia understand their relative's condition. In this article, we report on semi-structured interviews with 10 family members of people with advanced dementia, in a residential aged care facility. Using a qualitative, descriptive design, we explored family members' understandings of dementia, whether they were aware that it was a terminal condition, and the ways they developed their understandings. Findings revealed that the majority of family members could not recognize the terminal nature of dementia. Relying on predominantly lay understandings, they had little access to formal information and most failed to conceptualize a connection between dementia and death. Moreover, family members engaged in limited dialogue with aged care staff about such issues, despite their relatives being in an advanced stage of the disease. Findings from our study suggest that how family members understand their relative's condition requires greater attention. The development of staff/family partnerships that promote shared communication about dementia and dying may enhance family members' understandings of the dementia trajectory and the types of decisions they may be faced with during the more advanced stages of the disease.

The Quality of Pain Treatment in Community-Dwelling Persons with Dementia

BACKGROUND/AIMS

Despite pervasive and debilitating pain among elders, it is underassessed and undertreated; and cognitive impairment can add challenges. We assessed the quality of pain care for community-dwelling elderly patients with dementia.

METHODS

We phone interviewed 203 Veterans Affairs primary care outpatients with dementia and pain and reviewed medical records to score 15 quality indicators of pain assessment and management.

RESULTS

Pain assessment was documented for 98%, and a standard pain scale was used for 94%. Modified pain scales were rarely used. Though 70% self-reported pain of 'quite bad' or worse, charts documented no pain in 64%. When pain was identified, treatment was offered to 80%; but only 59% had a follow-up assessment within 6 months. Nonpharmacological interventions were underused.

CONCLUSION

Community-dwelling elders with dementia are underdiagnosed and undertreated for pain.

Changing practice in dementia care in the community: developing and testing evidence-based interventions, from timely diagnosis to end of life (EVIDEM)

Background

The needs of people with dementia and their carers are inadequately addressed at all key points in the illness trajectory, from diagnosis through to end-of-life care. The EVIDEM (Evidence-based Interventions in Dementia) research and development programme (2007–12) was designed to help change this situation within real-life settings.

Objectives

The EVIDEM projects were (1) evaluation of an educational package designed to enhance general practitioners’ (GPs’) diagnostic and management skills; (2) evaluation of exercise as therapy for behavioural and psychological symptoms of dementia (BPSD); (3) development of a toolkit for managing incontinence in people with dementia living at home; (4) development of a toolkit for palliative care for people with dementia; and (5) development of practice guidance on the use of the Mental Capacity Act (MCA) 2005.

Design

Mixed quantitative and qualitative methods from case studies to large database analyses, including longitudinal surveys, randomised controlled trials and research register development, with patient and public involvement built into all projects.

Setting

General practices, community services, third-sector organisations and care homes in the area of the North Thames Dementia and Neurodegenerative Diseases Research Network local research network.

Participants

People with dementia, their family and professional carers, GPs and community mental health team members, staff in local authority social services and third-sector bodies, and care home staff.

Main outcome measures

Dementia management reviews and case identification in general practice; changes in behavioural and psychological symptoms measured with the Neuropsychiatric Inventory (NPI); extent and impact of incontinence in community-dwelling people with dementia; mapping of pathways to death of people with dementia in care homes, and testing of a model of collaborative working between primary care and care homes; and understandings of the MCA 2005 among practitioners working with people with dementia.

Results

An educational intervention in general practice did not alter management or case identification. Exercise as a therapy for BPSD did not reduce NPI scores significantly, but had a significant positive effect on carer burden. Incontinence is twice as common in community-dwelling people with dementia than their peers, and is a hidden taboo within a stigma. Distinct trajectories of dying were identified (anticipated, unexpected and uncertain), and collaboration between NHS primary care and care homes was improved, with cost savings. The MCA 2005 legislation provided a useful working framework for practitioners working with people with dementia.

Conclusions

A tailored educational intervention for general practice does not change practice, even when incentives, policy pressure and consumer demand create a favourable environment for change; exercise has potential as a therapy for BPSD and deserves further investigation; incontinence is a common but unrecognised problem for people with dementia in the community; changes in relationships between care homes and general practice can be achieved, with benefits for people with dementia at the end of life and for the UK NHS; application of the MCA 2005 will continue to improve but educational reinforcements will help this. Increased research capacity in dementia in the community was achieved. This study suggests that further work is required to enhance clinical practice around dementia in general practice; investigate the apparent beneficial effect of physical activity on BPSD and carer well-being; develop case-finding methods for incontinence in people with dementia; optimise working relationships between NHS staff and care homes; and reinforce practitioner understanding of the MCA 2005.

What should we know about dementia in the 21st century? A Delphi consensus study

Background

Escalating numbers of people are experiencing dementia in many countries. With increasing consumer needs, there is anticipated growth in the numbers of people providing diagnostic evaluations, treatments, and care. Ensuring a consistent and contemporary understanding of dementia across all of these groups has become a critical issue. This study aimed to reach consensus among dementia experts from English speaking countries regarding essential and contemporary knowledge about dementia.

Methods

An online Delphi study was conducted to examine expert opinion concerning dementia knowledge with three rounds of data collection. A sample of dementia experts was selected by a panel of Australian experts, including a geriatrician and three professors of aged care. Purposive selection was initially undertaken with the sample expanded through snowballing. Dementia experts (N = 19) included geriatricians, psychologists, psychiatrists, neuroscientists, dementia advocates, and nurse academics from the United Kingdom, United States, and Australia. In the first round, these participants provided open-ended responses to questions determining what comprised essential knowledge about dementia. In the second round, responses were summarised into 66 discrete statements that participants rated on the basis of importance. In the third round, a rank-ordered list of the 66 statements and a group median were provided and participants rated the statements again. The degree of consensus regarding importance ratings was determined by assessing median, interquartile range, and proportion of experts scoring above predetermined thresholds. Correlation scores were calculated for each statement after the final round to identify changes in statement scores.

Results

The Delphi experts identified 36 statements about dementia that they considered essential to understanding the condition. Statements about care for a person experiencing dementia and their care giver represented the largest response category. Other statements, for which full or very high consensus was reached, related to dementia characteristics, symptoms and progression, diagnosis and assessment, and treatment and prevention.

Conclusions

These results summarise knowledge of dementia that is considered essential across expert representatives of key stakeholder groups from three countries. This information has implications for the delivery of care to people with the condition and the development of dementia education programs.

Delirium diagnostic and classification challenges in palliative care: subsyndromal delirium, comorbid delirium-dementia, and psychomotor subtypes

CONTEXT

Delirium often presents difficult diagnostic and classification challenges in palliative care settings.

OBJECTIVES

To review three major areas that create diagnostic and classification challenges in relation to delirium in palliative care: subsyndromal delirium (SSD), delirium in the context of comorbid dementia, and classification of psychomotor subtypes, and to identify knowledge gaps and research priorities in relation to these three areas of focus.

METHODS

We combined multidisciplinary input from delirium researchers and knowledge users at an international delirium study planning meeting and relevant PubMed literature searches as the knowledge synthesis strategy in this review.

RESULTS

We identified six (SSD), 33 (dementia), and 44 (psychomotor subtypes) articles of relevance in relation to the focus of our review. Recent literature data highlight the frequency and impact of SSD, the relevance of comorbid dementia, and the propensity for a hypoactive presentation of delirium in the palliative population. The differential diagnoses to consider are wide and include pain, fatigue, mood disturbance, psychoactive medication effects, and other causes for altered consciousness.

CONCLUSION

Challenges in the diagnosis and classification of delirium in people with advanced disease are compounded by the generalized disturbance of central nervous system function that occurs in the seriously ill, often with comorbid illness, including dementia. Further research is needed to delineate the pathophysiological and clinical associations of these presentations and thus inform therapeutic strategies. The expanding aged population and growing focus on dementia care in palliative care highlight the need to conduct this research.

Caregiver burden in end-of-life care: Advanced cancer and final stage of dementia

Objective:

Considering two advanced illnesses, cancer and end-stage dementia, the aim of this study was to describe the symptoms of caregiver psychological distress and burden.

Method:

In this cross-sectional study, regression analyses were calculated to explain the influence of psychological distress in caregiver burden. A t test was employed to compare differences between the symptoms of caregiver burden.

Results:

The percentage of psychological distress was similar between caregivers of cancer patients (77.6%) and caregivers of dementia patients (72.4%). In the regression analysis, cancer caregiver distress accounted for 27.9% of the variance in symptoms of burden, while dementia caregiver distress accounted for 24.4% of the variance in symptoms of burden. No significant differences were revealed when comparing caregiver burden symptoms between caregivers of the two advanced illnesses (t = 0.06; p = 0.94).

Significance of Results:

In end-of-life care for patients with dementia, due to significant levels of caregiver distress and burden symptoms, there is a need to support caregivers in the same way as is done for caregivers of cancer patients.

Support for families of patients dying with dementia: a qualitative analysis of bereaved family members' experiences and suggestions

OBJECTIVE

To explore and document the needs of family caregivers of patients dying with dementia and to identify how healthcare professionals can adequately support them.

METHOD

We employed a cross-sectional survey containing open-ended questions that were analyzed using qualitative methods.

RESULTS

Receiving information about the diagnosis and disease trajectory of dementia is essential for the caregiving families of people dying with the disease. However, at present the communication of information offered by professionals is not experienced as satisfying. Further aspects that require improvement concern issues related to time constraints, as well as practical and emotional support from professionals in the care setting. Family members would also like professionals to better assist them during and after the dying process.

SIGNIFICANCE OF RESULTS

Family members face multiple burdens while caring for their demented relatives and need more professional support during the course of the disease trajectory as well as in the terminal phase.

Transitions to palliative care for older people in acute hospitals: a mixed-methods study

Background

Improving the provision of palliative and end-of-life care is a priority for the NHS. Ensuring an appropriately managed ‘transition’ to a palliative approach for care when patients are likely to be entering the last year of life is central to current policy. Acute hospitals represent a significant site of palliative care delivery and specific guidance has been published regarding the management of palliative care transitions within this setting.

Aims

(1) to explore how transitions to a palliative care approach are managed and experienced in acute hospitals and to identify best practice from the perspective of clinicians and service users; (2) to examine the extent of potentially avoidable hospital admissions amongst hospital inpatients with palliative care needs.

Design

A mixed-methods design was adopted in two hospitals in England, serving diverse patient populations. Methods included (1) two systematic reviews; (2) focus groups and interviews with 58 health-care professionals to explore barriers to, and facilitators of, palliative care transitions in hospital; (3) a hospital inpatient survey examining palliative care needs and aspects of management including a self-/proxy-completed questionnaire, a survey of medical and nursing staff and a case note review; (4) in-depth interviews with 15 patients with palliative care needs; (5) a retrospective case note review of all inpatients present in the hospital at the time of the survey who had died within the subsequent 12 months; and (6) focus groups with 83 key decision-makers to explore the implications of the findings for service delivery and policy.

Results

Of the 514 patients in the inpatient survey sample, just over one-third (n = 185, 36.0%) met one or more of the Gold Standards Framework (GSF) prognostic indicator criteria for palliative care needs. The most common GSF prognostic indicator was frailty, with almost one-third of patients (27%) meeting this criteria. Agreement between medical and nursing staff and the GSF with respect to identifying patients with palliative care needs was poor. In focus groups, health professionals reported difficulties in recognising that a patient had entered the last 12 months of life. In-depth interviews with patients found that many of those interviewed were unaware of their prognosis and showed little insight into what they could expect from the trajectory of their disease. The retrospective case note review found that 35 (7.2%) admissions were potentially avoidable. The potential annual cost saving across both hospitals of preventing these admissions was approximately £5.3M. However, a 2- or 3-day reduction in length of stay for these admissions would result in an annual cost saving of £21.6M or £32.4M respectively.

Conclusions

Patients with palliative care needs represent a significant proportion of the hospital inpatient population. There is a significant gap between NHS policy regarding palliative and end-of-life care management in acute hospitals in England and current practice.

Advance care planning for people with dementia: benefits and challenges

Advance care planning (ACP) is a process being championed within health and social care, particularly since the publication of the UK Department of Health's 2008 End of Life Care Strategy. However, its implementation in dementia care is yet to be fully realised and can pose significant ethical and legal dilemmas for the generic and specialist workforce, the patient themselves, and their family or loved ones. Challenges may be attributable to inadequate communication, capacity issues, missed opportunities, and the perception that dementia is not a life-limiting illness. The aim of this paper is to highlight the benefits of ACP for individuals with dementia while appraising the recognised barriers to assist in developing some realistic recommendations for future practice.

Diagnosis and management of Alzheimer's disease: past, present and future ethical issues

There is great interest in the ethical issues associated with Alzheimer's disease (AD) and related dementias given the prevalence of AD and the evolving neuroscience landscape in matters of diagnoses and therapeutics. Much of the ethics discussion arises in the tension between the principle of not doing harm (principle of non-maleficence) in this vulnerable population and the development of effective treatments (principle of beneficence). Autonomy and capacity issues are also numerous, wide-ranging, and concern (1) day to day affairs such as driving safely and spending money wisely, (2) life-time events such as designating a legal representative in case of incapacity, making a will, (3) consenting to treatment and diagnostic procedures, (4) participating in research. The latter issue is particularly thorny and illustrates well the complexity of tackling concerns related to capacity. The impetus to protect AD patients has partly led to ethics regulation and policies making research on inapt patients more difficult because of stringent requirements for signed informed consent or for showing the value of the research to this specific patient population. New issues are arising that relate to earlier diagnosis using biomarkers and (possibly soon) the use of drugs that modify disease progression. We here summarize and discuss the different ethical issues associated with AD from a historical perspective, with emphasis on diagnostic and treatments issues.

Evaluating educational initiatives to improve palliative care for people with dementia: a narrative review

Dementia accounts for one in three deaths among people aged 65 and over, but end-of-life care for people with dementia is often sub-optimal. Palliative care for people with dementia poses particular challenges to those providing services, and current policy initiatives recommend education and training in palliative care for those working with patients with dementia. However, there are few evaluations of the effectiveness of dementia education and training. This paper presents a narrative review undertaken in 2011-2012 of evaluations of palliative care education for those working with people with dementia at the end of life. A total of eight papers were identified that described and evaluated such palliative care education; none reported benefits for people with dementia. There is a clear need to develop and evaluate educational interventions designed to improve palliative and end-of-life care for people with dementia. Some suggestions for educationally sound approaches are discussed.

Barriers and facilitators to the receipt of palliative care for people with dementia: the views of medical and nursing staff

BACKGROUND

The global prevalence of dementia is set to rise to almost 65 million people by 2030, providing policy makers and practitioners with significant challenges, not least within the realms of end-of-life care. The international literature would suggest that people with dementia may benefit from palliative forms of care, but evidence indicates that many fail to access such provision at the end of life. The role of the health care team is pivotal if people with dementia are to benefit from the transition to palliative care.

AIM

This paper reports on qualitative research conducted in the UK that sought to explore the experiences of health care practitioners working in palliative care and sought to establish the issues relating to end-of-life care for people with dementia.

DESIGN

Eight focus groups and four individual interviews were held. Data were analysed using a thematic approach.

SETTING/PARTICIPANTS

The study included palliative care practitioners (n = 58) including medical, nursing and allied health professionals. Participants were recruited from acute hospitals, general practice, hospices and specialist palliative care units in the UK.

RESULTS

Four themes were identified: Making the transition; Competence challenged; 'The long view' and Working together. Whilst there exists good practice in this area, the barriers to timely and appropriate transitions to palliative care for people with dementia and their families continue to exist. The paper concludes with recommendations for policy and practice development.

Providing Quality Palliative Care in End-Stage Alzheimer Disease

Providing quality palliative care is a daunting task profoundly impacted by diminished patient capacity at the end of life. Alzheimer disease (AD) is a disorder that erases our memories and is projected to increase dramatically for decades to come. By the time the patients with AD reach the end stage of the disease, the ability of patients to provide pertinent subjective complaints of pain and discomfort would have vanished. Historical perspectives of palliative care, exploration of the AD process, ethical issues, and crucial clinical considerations are provided to improve the understanding of disease progression and quality of care for patients with end-stage AD.

Nutrition in severe dementia

An increasing proportion of older adults with Alzheimer's disease or other dementias are now surviving to more advanced stages of the illness. Advanced dementia is associated with feeding problems, including difficulty in swallowing and respiratory diseases. Patients become incompetent to make decisions. As a result, complex situations may arise in which physicians and families decide whether artificial nutrition and hydration (ANH) is likely to be beneficial for the patient. The objective of this paper is to present methods for evaluating the nutritional status of patients with severe dementia as well as measures for the treatment of nutritional disorders, the use of vitamin and mineral supplementation, and indications for ANH and pharmacological therapy.

Dementia deaths in hospice: a retrospective case note audit

Dementia is now recognized as a progressive terminal illness and it is established that people with dementia have significant palliative care needs as they approach the end of life. However, population prevalence studies suggest that very few people with dementia access hospice services in the UK. The literature further suggests that hospice staff may be inadequately prepared to care for people with dementia. A retrospective internal case note audit covering a 3-month period of referrals was undertaken in one hospice in the south of England as part of work to establish staff education requirements arising from patient make-up. Only patients over the age of 65 were included. Of the 288 case notes audited, 9% of the patients had either been diagnosed with dementia or suffered with dementia as a comorbidity. The results of the audit suggest that the number of people with dementia referred to hospice services may have increased in the last decade. This is in keeping with expectations and future predictions resulting from increased disease surveillance and an increasingly ageing population.

The challenges of providing palliative care for older people with dementia

Palliative care seems the right approach to dementia, except that it suggests a dichotomy between cure and care. As in cancer care, supportive care provides a broader framework, viewing dementia from the time of diagnosis until death and bereavement. The challenge is to find the right approach to the individual. This challenge arises in the person's own home, in long-term care homes, and in hospitals. The challenging features of palliative care for older people with dementia are found in connection with the use of antibiotics, antipsychotics, and other medications, as well as in decisions about whether the person is in pain or in distress, or whether artificial feeding should be contemplated or not, as well as about the use of advance care plans. In short, the challenges are essentially ethical as well as clinical. The right approach will be the one that recognizes this facet of clinical care.

Dying well with dementia: qualitative examination of end-of-life care

BACKGROUND

People with dementia often die badly, receiving end-of-life care of poorer quality than that given to those who are cognitively intact.

AIMS

To define good end-of-life care for people with dementia and identify how it can be delivered across care settings in the UK.

METHOD

In-depth interviews were conducted with 27 bereaved family carers and 23 care professionals recruited from the community, care homes, general hospitals and continuing care units. Data were analysed using the constant comparison method.

RESULTS

The data highlighted the challenge and imperative of 'dementia-proofing' end-of-life care for people with dementia. This requires using dementia expertise to meet physical care needs, going beyond task-focused care and prioritising planning and communication with families.

CONCLUSIONS

The quality of end-of-life care exists on a continuum across care settings. Together, the data reveal key elements of good end-of-life care and that staff education, supervision and specialist input can enable its provision.

Withholding, discontinuing and withdrawing medications in dementia patients at the end of life: a neglected problem in the disadvantaged dying?

Recent years have seen a growing recognition that dementia is a terminal illness and that patients with advanced dementia nearing the end of life do not currently receive adequate palliative care. However, research into palliative care for these patients has thus far been limited. Furthermore, there has been little discussion in the literature regarding medication use in patients with advanced dementia who are nearing the end of life, and discontinuation of medication has not been well studied despite its potential to reduce the burden on the patient and to improve quality of life. There is limited, and sometimes contradictory, evidence available in the literature to guide evidence-based discontinuation of drugs such as acetylcholinesterase inhibitors, antipsychotic agents, HMG-CoA reductase inhibitors (statins), antibacterials, antihypertensives, antihyperglycaemic drugs and anticoagulants. Furthermore, end-of-life care of patients with advanced dementia may be complicated by difficulties in accurately estimating life expectancy, ethical considerations regarding withholding or withdrawing treatment, and the wishes of the patient and/or their family. Significant research must be undertaken in the area of medication discontinuation in patients with advanced dementia nearing the end of life to determine how physicians currently decide whether medications should be discontinued, and also to develop the evidence base and provide guidance on systematic medication discontinuation.

End of life care for community dwelling older people with dementia: an integrated review

OBJECTIVE

To review the evidence for end-of-life care for community dwelling older people with dementia (including those resident in care homes).

DESIGN

An integrated review synthesised the qualitative and quantitative evidence on end-of-life care for community dwelling older people with dementia. English language studies that focused on prognostic indicators for end-of-life care, assessment, support/relief, respite and educational interventions for community dwelling older people with dementia were included. A user representative group informed decisions on the breadth of literature used. Each study selected was screened independently by two reviewers using a standardised check list.

RESULTS

Sixty eight papers were included. Only 17% (12) exclusively concerned living and dying with dementia at home. Six studies included direct evidence from people with dementia. The studies grouped into four broad categories: Dementia care towards the end of life, palliative symptom management for people with dementia, predicting the approach of death for people with dementia and decision-making. The majority of studies were descriptive. The few studies that developed dementia specific tools to guide end of life care and outcome measures specific to improve comfort and communication, demonstrated what could be achieved, and how much more needs to be done.

CONCLUSIONS

Research on end-of-life care for people with dementia has yet to develop interventions that address the particular challenges that dying with dementia poses. There is a need for investigation of interventions and outcome measures for providing end-of-life care in the settings where the majority of this population live and die.

Advance Care Planning: An opportunity for person-centred care for people living with dementia

Many people want to be able to plan ahead, so that if in the future they cannot make decisions or do things, their wishes will be known. This is called Advance Care Planning (ACP). Although it is part of official NHS policy (NHS End of Life Care Planning), ACP is hardly ever done, and it may become more difficult once a person has memory problems. In the UK, there is very little research into ACP. By the time someone has signs of dementia, families often become involved. We are uncertain how this affects ACP and the views of the person with dementia, particularly with the new Mental Capacity Act which allow families to comment on health, as well as financial, issues. Our study will be exploring the area of ACP, especially in dementia, by

• looking at the experience of other countries through a systematic review of the existing literature;

• finding out what people who have carried out ACP in this country think through interviews and focus groups;

• considering what factors might help professionals to encourage the process of ACP in practice; and

• looking at how ACP might be done better for people with dementia.

The ultimate aim of our study is to produce guidance on ACP for both people with dementia, their families and health care professionals.
