The attitudes of carers and old age psychiatrists towards the treatment of potentially fatal events in end-stage dementia

Factors influencing palliative care in advanced dementia: a systematic review

Background

Dementia is a progressive neurodegenerative life-limiting disease. The international literature indicates that patients with advanced dementia can benefit from palliative care (PC) provided during the end-of-life phase. However, evidence indicates that currently many fail to access such provision despite the increased recognition of their palliative needs.

Aim

To investigate the factors influencing provision of PC services for people with advanced dementia.

Methods

A systematic review of mixed method studies written in English was undertaken. 11 electronic databases including Embase, Medline, PubMed, CINAHL and Scopus from 2008 to 2018 were searched. Narrative synthesis and content analysis were used to analyse and synthesise the data.

Key findings

In total, 34 studies were included. 25 studies providing qualitative data, 6 providing quantitative data and 3 mixed methods studies. The findings identified organisational, healthcare professionals and patients-related barriers and facilitators in provision of PC for people with advanced dementia from perspective of stakeholders across different care settings. The most commonly reported barriers are lack of skills and training opportunities of the staff specific to PC in dementia, lack of awareness that dementia is a terminal illness and a palliative condition, pain and symptoms assessment/management difficulties, discontinuity of care for patients with dementia and lack of coordination across care settings, difficulty communicating with the patient and the lack of advance care planning.

Conclusions

Even though the provision of PC was empirically recognised as a care step in the management of dementia, there are barriers that hinder access of patients with dementia to appropriate facilities. With dementia prevalence rising and no cure on the horizon, it is crucial that health and social care regulatory bodies integrate a palliative approach into their care using the identified facilitators to achieve optimal and effective PC in this population.

Caring for a family member or friend with dementia at the end of life: A scoping review and implications for palliative care practice

BACKGROUND

Although people with dementia receive substantial care from informal sources, there is limited research available that investigates how these carers experience end-of-life care.

AIM

This review aimed to identify what is currently known about carers' experiences of providing end-of-life care to a family member or friend with dementia and draw implications for palliative care policy and service provision.

DESIGN

A scoping literature review was conducted, first using a targeted key word search, followed by assessments of eligibility based on title and then abstract content.

DATA SOURCES

Records were sourced through PsycINFO, PubMed and CINAHL databases. Peer-reviewed papers published between 2000 and 2016, reporting on data collected directly from carers, were included for review.

RESULTS

Carers' experience centred on relationships (with care recipients, family and friends and health care professionals) and the specific context of caring for someone with dementia. These broad categories of carers' experiences had clear influences on them personally, particularly in relation to their sense of self and their wellbeing.

CONCLUSION

Palliative care services would benefit from ensuring holistic approaches to supporting people with dementia, their carers and wider family networks. Tailoring services to the specific context of dementia would enable effective, personalised support throughout extended periods leading up to care recipient death as well as through the challenges faced beyond bereavement.

A systematic review of barriers and facilitators to and interventions for proxy decision-making by family carers of people with dementia

BACKGROUND

Relatives of people with dementia report that proxy decision-making is difficult and distressing. We systematically reviewed the literature about barriers and facilitators to family carers of people with dementia making proxy decisions, and interventions used to facilitate their decision-making.

METHODS

We searched electronic databases and references of included papers up to February 2014. Two authors independently evaluated study quality using a checklist.

RESULTS

We included the 30/104 papers from our search which fitted predetermined criteria and prioritized higher quality papers. Family carers report that proxy decision-making is challenging and can be distressing, especially when decisions are made against the wishes of the care recipient and support from healthcare professionals is lacking. Decision-specific manualized aids have been developed, and while results for those supporting decisions about respite and percutaneous endoscopic gastrostomy (PEG) feeding have shown promising results in pilot trials, no intervention has yet been shown to significantly reduce decisional conflict or carer burden, or increase knowledge in randomized controlled trials; a decision aid for advance care planning increased decisional conflict.

CONCLUSIONS

We recommend development and testing of decision aids targeting the decisions carers report finding most distressing, including those around where people should live, accessing services, and end of life treatments. Being provided with information to make decisions which have not previously been considered may increase feelings of conflict, suggesting these aids should be carefully targeted.

Do people with dementia die at their preferred location of death? A systematic literature review and narrative synthesis

AIM

place of death is an important component of the quality of a person's death. The aim of this study was to undertake a systematic review and narrative synthesis of the literature concerning place of death of people with dementia and the preferences for location of death of people with dementia as well as family carers and healthcare providers preferred location of death for patients with dementia.

METHODS AND RESULTS

studies relying on death certificate data show that patients with dementia die more commonly in care homes than other locations contrasting with prospective studies which show that death is more common in own residence and hospital. Age (older), gender (male), availability of hospital and nursing home beds and enrolment in hospice, influence place of death. There is very limited evidence of patients, family carers and healthcare providers' views on preferred location of death for patients with dementia and the only study included reported that, family carers views are more agreed to rather than patients own views regarding place of death.

CONCLUSION

this study on place of death raises exploratory questions on end-of-life care for patients with dementia which has implications on health and social care policies related to dementia.

Care of the dying neurologic patient

The causes of death in patients with neurodegenerative diseases are important information for patients and relatives because misleading information causes additional burdens. Early and frank discussion about disease progression, the causes of death, and end-of-life decisions might support the patient's and family's acceptance of the dying process and also helps physicians to frame treatment goals more explicitly. These goals include the place of death as well as medication administered at the end of life. The Liverpool Care Pathway provides a useful tool to standardize the care at the end of life that contributes to individual decisions and care plans. The prescription of medication at the end of life in various neurodegenerative diseases differs from treatment during the earlier phases of the diseases, not only because of swallowing difficulties but also in terms of symptom control.

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.

The effectiveness and appropriateness of a palliative approach to care for people with advanced dementia: a systematic review

BACKGROUND

Dementia is a progressive and incurable disease which presents many challenges to care providers, particularly in terms of end-of-life care. A palliative approach; that is an approach to care which seeks to ease burdensome symptoms without attempting curative treatment, has been suggested as the most appropriate framework for addressing the needs of these people.

OBJECTIVES

The overall objective was to establish best practice in relation to palliative care for people with advanced dementia in terms of effectiveness and appropriateness.

SEARCH STRATEGY

The search strategy aimed to find both published and unpublished English language studies, published between 1997 and 2009. A three-step search strategy was utilised in each component of this review.

CRITICAL APPRAISAL

Quantitative, qualitative and discursive text articles were included in this review. Articles were assessed for congruence to the review criteria and then critically appraised for quality using the appropriate JBI tool.

DATA COLLECTION AND ANALYSIS

Data were extracted using the appropriate JBI data extraction tool for each methodology. No quantitative meta-analysis was possible due to clinical and statistical heterogeneity. Qualitative synthesis was performed with the JBI QARI tool. Discursive textual synthesis was performed with the JBI NOTARI tool.

RESULTS

Quantitative studies recommended the use of do not resuscitate, do not hospitalise orders and other forms of advance directives to prevent interventions unwanted by the patient and/or their family. Feeding tubes and the use of intravenous antibiotics were not found to be an effective intervention. Interventions designed to treat the burdensome symptoms of advanced dementia (such as pain and agitation) were found to be of the most benefit to patients.Qualitative analysis found it distressing for families to discuss or plan for, a poor quality of life for their loved one during the process of dying. Decisions concerned with palliative treatment for the person with advanced dementia were found to be complicated by knowledge differences, lack of understanding of the disease trajectory of dementia, the unpredictable nature of dementia itself and religious and socio-economical issues. Textual analysis found that a palliative approach to end of life care in advanced dementia is both appropriate and effective in terms of benefit to patients and their significant others.Despite the large volume of data retrieved and analysed for this review, no studies examining the role of case-conferencing for managing the introduction of palliative care or managing a palliative approach met the inclusion criteria for this systematic review.

IMPLICATIONS FOR PRACTICE

IMPLICATIONS FOR FUTURE RESEARCH: There is a need for further studies in the area of palliation and advanced dementia, particularly high quality studies investigating palliative care case conferencing and other methods of arranging and planning end of life care for people with dementia.

CONCLUSION

There is some evidence to suggest that a palliative approach is both effective and appropriate for use with people who have advanced dementia. There is no evidence for or against the use of case-conferencing as a method of arranging care for people with advanced dementia.

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.

Treatment decisions regarding hospitalization and surgery for nursing home residents with advanced dementia: the CareAD Study

BACKGROUND

Dementia differs from other terminal illnesses both in its slow progression and the fact that patients and family members often do not perceive it as a cause of death. Furthermore, because decisional incapacity is almost universal in patients with advanced dementia, decisions must be made by surrogates. However, little is known about the factors that influence how surrogates make decisions for persons with late-stage dementia.

METHODS

The setting was the first wave of a study of patients with advanced dementia in three Maryland nursing homes (The Care of Nursing Home Residents with Advanced Dementia Study). Of 125 consented participants, 123 residents and their surrogates provided adequate information and agreed to interviews and medical record reviews. Bivariate analysis and logistic regression models were used to explore whether variables related to demographics, illness, communication and surrogate background were associated with surrogate decisions to not provide aggressive treatments (i.e. hospitalization or surgery).

RESULTS

Treatment decisions regarding aggressive medical care had been made by 81% of surrogates over the preceding 6 months. In bivariate analysis the following factors were significantly associated with not providing aggressive care: resident and surrogate of white race, older surrogate age, worse resident medical illness, worse surrogate perception of resident quality of life, presence of a 'do not hospitalize' order (DNH), and more contact with nurses. In the multivariate analysis, resident white race and presence of a DNH were significant predictors of surrogate decisions to not provide aggressive treatments. Treatment decisions were not associated with surrogate relationship or religiosity.

CONCLUSIONS

Treatment decisions for individuals with advanced dementia are mostly strongly associated with the patient's race and presence of DNH and less so with changeable features of illness or environment.
