A systematic review of the integration of palliative care in dementia management

End of life care for people with dementia and comorbid cancer: recent studies and research gaps

PURPOSE OF REVIEW

This narrative review examines recent research on end of life (EOL) care for people with dementia and comorbid cancer, highlighting the complexity and challenge of providing effective EOL care for this group and areas of interest for future research.

RECENT FINDINGS

People with cancer and dementia and their family/supporters have more complex care and support needs at EOL that are less well met than those of older adults with cancer alone, including questionable use of aggressive EOL care interventions, poorer access to specialist palliative care teams and poor pain management. Those diagnosed with dementia at the same time as, or after their cancer diagnosis, are at greater risk of aggressive EOL care and EOL cancer treatment and care plans that are not able to meet their care needs as dementia progresses.

SUMMARY

There is a lack of research on EOL care for people with cancer and dementia. There is little understanding of what good care for this population looks like and if and how EOL care can best meet the needs of people with cancer and dementia or their carers/supporters. More research is needed to inform improved care for this population.

Palliative Care Interventions for Persons With Neurodegenerative Disease: A Scoping Review of Clinical Trial Study Design Features

Background: Within palliative care research, best practice guidelines to conduct scientifically rigorous clinical trials for neurodegenerative diseases are underexplored. This patient population experiences unique challenges, including fluctuations in cognitive capacity, care partner (CP) and proxy involvement, and high adverse events (AEs), that necessitate special consideration when designing clinical trials. Objective: The objective of this study was to describe and identify clinical trial design features that have been documented in studies involving a neuropalliative intervention for persons with neurodegenerative diseases, highlighting features that have been adapted for this unique patient population. Design: We conducted a scoping review of clinical trials with a neuropalliative intervention for persons with neurodegenerative disease. We searched Cochrane, Web of Science, EMBASE, Scopus, and PubMed (MEDLINE) databases for articles published in English between 1950 and 2023. Two reviewers screened, extracted, and synthesized data from the included articles. A third reviewer adjudicated instances of conflict. The data were analyzed using a thematic framework approach. Results: Of 1025 texts, 44 articles were included. Seven study design features were analyzed: (1) consent, (2) proxies and CPs, (3) recruitment strategies, (4) retention strategies, (5) choice of comparator, (6) AEs, and (7) internal validity. This scoping review found disparities in study design features around structured consent, proxies and CPs, comparators, and AEs. Conclusions: To date, neuropalliative care clinical trials have had varied study designs and the majority of research has focused on dementia. Research guideline development for high-quality neuropalliative care clinical trials is greatly needed across the range of neurodegenerative diseases. To increase the scientific rigor of clinical trials and neuropalliative care, we recommend a standardized capacity assessment for consent, defining conditions for the CP, proxy, and AEs, systematizing appropriate comparators, and outlining preemptive recruitment and retention strategies to address the broader unpredictable challenges of palliative care research.

A palliative care goals model for people with dementia and their family: Consensus achieved in an international Delphi study

BACKGROUND

Advance care planning in dementia includes supporting the person and their family to consider important goals of care. International research reports the importance of psycho-social-spiritual aspects towards end of life.

AIM

To develop a multidimensional international palliative care goals model in dementia for use in practice.

DESIGN

International Delphi study integrating consensus and evidence from a meta-qualitative study. The Delphi panel rated statements about the model on a 5-point agreement scale. The criteria for consensus were pre-specified.

SETTING/PARTICIPANTS

Seventeen researchers from eight countries developed an initial model, and 169 candidate panellists were invited to the international online Delphi study.

RESULTS

Panellists (107; response 63.3%) resided in 33 countries. The model comprised four main care goals: (1) Comfort ensured; (2) Control over function maintained; (3) Identity protected and personhood respected and (4) Coping with grief and loss-person and caregiver supported. The model reflects how needs and care goals change over time with the progression of dementia, concluding with bereavement support. The first version of the model achieved a consensus after which it was slightly refined based on feedback. We did not achieve a consensus on adding a goal of life prolongation, and on use of the model by people with dementia and family themselves.

CONCLUSION

A new palliative care goals model for people with dementia and their families includes relationship aspects for use by professionals and achieved a consensus among a panel with diverse cultural background. The position of life prolongation in relation to palliative care goals needs further research.

Characterizing Canadian Social Workers Willing to Be Involved in Medical Assistance in Dying for Persons Lacking Decisional Capacity

Medical assistance in dying (MAID) is available in Canada for competent persons meeting the legal requirements. Extending access to persons lacking decisional capacity is being considered. Social workers may be called upon to accompany these persons through the MAID process. As part of a larger survey, we asked social workers from Quebec whether they would be willing to be involved should advance requests for MAID be legalized. Of the 367 respondents, 291 replied that they would. Using multivariable logistic regression, we identified characteristics that distinguish them from the other social workers surveyed: importance of religious or spiritual beliefs, being born in Canada, having received assisted-death requests from families, professional experiences with MAID, and dreading the prospect of participating in MAID for persons lacking decisional capacity. These findings underline the need for educational interventions that would increase social workers' confidence in providing high-quality care to clients who opt for MAID.

Developing neuropalliative care for sporadic Creutzfeldt-Jakob Disease

We aimed to identify targets for neuropalliative care interventions in sporadic Creutzfeldt-Jakob disease by examining characteristics of patients and sources of distress and support among former caregivers. We identified caregivers of decedents with sporadic Creutzfeldt-Jakob disease from the University of California San Francisco Rapidly Progressive Dementia research database. We purposively recruited 12 caregivers for in-depth interviews and extracted associated patient data. We analysed interviews using the constant comparison method and chart data using descriptive statistics. Patients had a median age of 70 (range: 60-86) years and disease duration of 14.5 months (range 4-41 months). Caregivers were interviewed a median of 22  (range 11-39) months after patient death and had a median age of 59 (range 45-73) years. Three major sources of distress included (1) the unique nature of sporadic Creutzfeldt-Jakob disease; (2) clinical care issues such as difficult diagnostic process, lack of expertise in sporadic Creutzfeldt-Jakob disease, gaps in clinical systems, and difficulties with end-of-life care; and (3) caregiving issues, including escalating responsibilities, intensifying stress, declining caregiver well-being, and care needs surpassing resources. Two sources of support were (1) clinical care, including guidance from providers about what to expect and supportive relationships; and (2) caregiving supports, including connection to persons with experience managing Creutzfeldt-Jakob disease, instrumental support, and social/emotional support. The challenges and supports described by caregivers align with neuropalliative approaches and can be used to develop interventions to address needs of persons with sporadic Creutzfeldt-Jakob disease and their caregivers.

Informal care-givers' attitudes towards medical assistance in dying for persons with dementia

Medical assistance in dying (MAID) is legal in Canada but cannot be accessed through an advance request. Some data suggest that informal care-givers of persons with dementia support the legalisation of advance requests for MAID. Opponents argue that care-givers' support is due to society's failure to address their well-documented burden and unmet needs. To our knowledge, this assumption has never been tested. To fill this knowledge gap, we conducted a survey among 204 Canadian informal care-givers of persons with dementia to (a) elicit their attitudes towards allowing no longer competent adults to access MAID through an advance request, and (b) test the hypothesis that attitudes are in part driven by the level of burden experienced by care-givers and unmet needs for support. Attitudes were elicited with a clinical vignette involving a woman with Alzheimer's disease who requests MAID while still competent, or through an advance request for the time after she would lose decisional capacity. Informal care-givers' support for MAID ranged from 60 per cent in the scenario where the person is still competent and likely has several more years to live, to 87 per cent when she is depicted as no longer competent, in severe distress and close to death. Quality-of-life considerations and the value of self-determination were key arguments in support of legalising advance requests for MAID. Using multivariable logistic regression, we found no evidence that burden and unmet support needs influence attitudes towards advance requests for MAID, after controlling for other determinants. These findings contribute new insights into people's attitudes towards the sensitive issue of whether MAID should be extended to persons with dementia-induced decisional incapacity.

When to initiate palliative care in neurology

Life-limiting and life-threatening neurologic conditions often progress slowly. Patients live with a substantial symptom burden over a long period of time, and there is often a high degree of functional and cognitive impairment. Because of this, the most appropriate time to initiate neuropalliative care is often difficult to identify. Further challenges to the incorporation of neuropalliative care include communication barriers, such as profound dysarthria or language impairments, and loss of cognitive function and decision-making capacity that prevent shared decision making and threaten patient autonomy. As a result, earlier initiation of at least some components of palliative care is paramount to ensuring patient-centered care while the patient is still able to communicate effectively and participate as fully as possible in their medical care. For these reasons, neuropalliative care is also distinct from palliative care in oncology, and there is a growing evidence base to guide timely initiation and integration of neuropalliative care. In this chapter, we will focus on when to initiate palliative care in patients with life-limiting, life-threatening, and advanced neurologic conditions. We will address three main questions, which patients with neurologic conditions will benefit from initiation of palliative care, what aspects of neurologic illness are most amenable to neuropalliative care, and when to initiate neuropalliative care?

Examining the role of specialist palliative care in geriatric care to inform collaborations: a survey on the knowledge, practice and attitudes of geriatricians in providing palliative care

BACKGROUND

The global population is ageing, and rates of multimorbidity and chronic illness are rapidly rising. Given specialist palliative care has been shown to improve overall care and reduce health care costs, how best to provide this care to older people is internationally significant.

AIM

To examine the knowledge, attitudes and practices of geriatricians in providing palliative care and working with specialist palliative care services. We also aimed to capture self-reported barriers, confidence and satisfaction in providing palliative care.

DESIGN

A prospective cross-sectional study surveying Australasian geriatricians was conducted.

SETTING/PARTICIPANTS

This was a voluntary anonymous online survey, distributed to all full members of the Australian and New Zealand Society of Geriatric Medicine.

RESULTS

A total of 168 completed responses were received; 58.3% were female and 36.6% had over 20 years of clinical experience. Most geriatricians (85%) reported caring for patients in their last 12 months of life represented a substantial aspect or most of their practice. Geriatricians overwhelmingly believed they should coordinate care (84%) and derived satisfaction from providing palliative care (95%). The majority (69%) believed all patients with advanced illness should receive concurrent specialist palliative care. Regarding knowledge, participants scored an average of 13.5 correct answers out of 18 in a Modified Palliative Care Knowledge Test.

CONCLUSIONS

Geriatricians find reward in providing generalist palliative care to their patients; however, potential exists for improved collaborations with specialist palliative care services. An evidence base for geriatric patients who benefit most from specialist palliative care services is needed to improve resourcing, collaborative practice and ultimately palliative care delivery.

No difference in effects of 'PACE steps to success' palliative care program for nursing home residents with and without dementia: a pre-planned subgroup analysis of the seven-country PACE trial

Background

‘PACE Steps to Success’ is a multicomponent training program aiming to integrate generalist and non-disease-specific palliative care in nursing homes. This program did not improve residents’ comfort in the last week of life, but it appeared to improve quality of care and dying in their last month of life. Because this program included only three dementia-specific elements, its effects might differ depending on the presence or stage of dementia. We aimed to investigate whether the program effects differ between residents with advanced, non-advanced, and no dementia.

Methods

Pre-planned subgroup analysis of the PACE cluster-randomized controlled trial in 78 nursing homes in seven European countries. Participants included residents who died in the previous 4 months. The nursing home staff or general practitioner assessed the presence of dementia; severity was determined using two highly-discriminatory staff-reported instruments. Using after-death questionnaires, staff assessed comfort in the last week of life (Comfort Assessment in Dying–End-of-Life in Dementia-scale; primary outcome) and quality of care and dying in the last month of life (Quality of Dying in Long-Term Care scale; secondary outcome).

Results

At baseline, we included 177 residents with advanced dementia, 126 with non-advanced dementia and 156 without dementia. Post-intervention, respectively in the control and the intervention group, we included 136 and 104 residents with advanced dementia, 167 and 110 with non-advanced dementia and 157 and 137 without dementia. We found no subgroup differences on comfort in the last week of life, comparing advanced versus without dementia (baseline-adjusted mean sub-group difference 2.1; p-value = 0.177), non-advanced versus without dementia (2.7; p = 0.092), and advanced versus non-advanced dementia (− 0.6; p = 0.698); or on quality of care and dying in the last month of life, comparing advanced and without dementia (− 0.6; p = 0.741), non-advanced and without dementia (− 1.5; p = 0.428), and advanced and non-advanced dementia (0.9; p = 0.632).

Conclusions

The lack of subgroup difference suggests that while the program did not improve comfort in dying residents with or without dementia, it appeared to equally improve quality of care and dying in the last month of life for residents with dementia (regardless of the stage) and those without dementia. A generalist and non-disease-specific palliative care program, such as PACE Steps to Success, is a useful starting point for future palliative care improvement in nursing homes, but to effectively improve residents’ comfort, this program needs further development.

Referral criteria to specialist palliative care for patients with dementia: A systematic review

BACKGROUND

Patients with dementia often have significant symptom burden and a progressive course of functional deterioration. Specialist palliative care referral may be helpful, but it is unclear who and when patients should be referred. We conducted a systematic review of the literature to examine referral criteria for palliative care among patients with dementia.

METHODS

We searched Ovid MEDLINE, Ovid Embase, Ovid PsycInfo, Cochrane Library, PubMed, and CINAHL databases for articles from inception to December 3, 2019, related to specialist palliative care referral for dementia. Two investigators independently reviewed the citations for inclusion, extracted the referral criteria, and categorized them thematically.

RESULTS

Of the 1788 citations, 59 articles were included in the final sample. We identified 13 categories of referral criteria, including 6 disease-based and 7 needs-based criteria. The most commonly discussed criterion was "dementia stage" (n = 43, 73%), followed by "new diagnosis of dementia" (n = 17, 29%), "medical complications of dementia" (n = 12, 20%), "prognosis" (n = 11, 19%), and "physical symptoms" (n = 11, 19%). Under dementia stage, 37/44 (84%) articles recommended a palliative care referral for advanced dementia. Pneumonia (n = 6, 10%), fall/fracture (n = 4, 7%), and decubitus ulcers (n = 4, 7%) were most commonly discussed complications to trigger a referral. Under prognosis, the time frame for referral varied from <2 years of life expectancy to <6 months. 3 (5%) of articles recommended "surprise question" as a potential trigger.

CONCLUSIONS

This systematic review highlighted the lack of consensus regarding referral criteria for palliative care in patients with dementia and the need to identify timely triggers to standardize referral.

Practical nursing recommendations for palliative care for people with dementia living in long-term care facilities during the COVID-19 pandemic: A rapid scoping review

BACKGROUND

The acute nature of COVID-19 and its effects on society in terms of social distancing and quarantine regulations affect the provision of palliative care for people with dementia who live in long-term care facilities. The current COVID-19 pandemic poses a challenge to nursing staff, who are in a key position to provide high-quality palliative care for people with dementia and their families.

OBJECTIVE

To formulate practice recommendations for nursing staff with regard to providing palliative dementia care in times of COVID-19.

DESIGN AND METHOD

A rapid scoping review following guidelines from the Joanna Briggs Institute. Eligible papers focused on COVID-19 in combination with palliative care for older people or people with dementia and informed practical nursing recommendations for long-term care facilities. After data extraction, we formulated recommendations covering essential domains in palliative care adapted from the National Consensus Project's Clinical Practice Guidelines for Quality Palliative Care.

DATA SOURCES

We searched the bibliographic databases of PubMed, CINAHL and PsycINFO for academic publications. We searched for grey literature using the search engine Google. Moreover, we included relevant letters and editorials, guidelines, web articles and policy papers published by knowledge and professional institutes or associations in dementia and palliative care.

RESULTS

In total, 23 documents (7 (special) articles in peer-reviewed journals, 6 guides, 4 letters to editors, 2 web articles (blogs), 2 reports, a correspondence paper and a position paper) were included. The highest number of papers informed recommendations under the domains 'advance care planning' and 'psychological aspects of care'. The lowest number of papers informed the domains 'ethical care', 'care of the dying', 'spiritual care' and 'bereavement care'. We found no papers that informed the 'cultural aspects of care' domain.

CONCLUSION

Literature that focuses specifically on palliative care for people with dementia in long-term care facilities during the COVID-19 pandemic is still largely lacking. Particular challenges that need addressing involve care of the dying and the bereaved, and ethical, cultural and spiritual aspects of care. Moreover, we must acknowledge grief and moral distress among nursing staff. Nursing leadership is needed to safeguard the quality of care and nursing staff should work together within an interprofessional care team to initiate advance care planning conversations in a timely manner, to review and document advance care plans, and to adapt goals of care as they may change due to the COVID-19 situation. Tweetable abstract: The current COVID-19 pandemic affects people living with dementia, their families and their professional caregivers. This rapid scoping review searched for academic and grey literature to formulate practical recommendations for nursing staff working in long-term care facilities on how to provide palliative care for people with dementia in times of COVID-19. There is a particular need for grief and bereavement support and we must acknowledge grief and moral distress among nursing staff. This review exposes practice and knowledge gaps in the response to COVID-19 that reflect the longstanding neglect and weaknesses of palliative care in the long-term care sector. Nursing leadership is needed to safeguard the quality of palliative care, interprofessional collaboration and peer support among nursing staff.

Characteristics and Outcomes of Dementia Patients Who Receive Inpatient Palliative Care Consultation

BACKGROUND/OBJECTIVES

Acute hospitalization may be an ideal opportunity to introduce palliative care to dementia patients, who may benefit from symptom management and goals of care discussions. We know little about patients who receive inpatient palliative care consultations (IPCCs).

DESIGN

Retrospective analysis using electronic medical record.

SETTING

Tertiary academic medical center and affiliated community hospital.

PARTICIPANTS

Patients with dementia by International Classification of Diseases diagnosis, 65 years or older, hospitalized between July 1, 2015, and December 31, 2015.

MEASUREMENTS

We used χ² and t-test/Mann-Whitney U test to compare characteristics (living arrangement, advanced dementia markers, diagnoses of delirium and dementia with behavior disturbance, and admitting diagnosis) and outcomes (change in code status, length of stay [LOS], discharge disposition, and discharge medications for symptom management) of patients who did and did not receive IPCC. Patients were matched on sex, age, and race.

RESULTS

Among 927 hospitalized patients with dementia, 17% received IPCC (N = 157). Patients who received IPCC were more likely to be admitted from a nursing facility (35.7% vs 12.7%; P < .0001), experience delirium (71.3% vs 57.3%; P = .01), have behavior disturbance (23.6% vs 13.4%; P = .02), have a pressure ulcer at admission (26.1% vs 11.5%; P = .001), have hypernatremia (12.7% vs 3.2%; P = .002), and be bedbound (20.4% vs 3.2%; P < .000). Patients who received IPCC had a longer LOS (median = 5.9 vs 4.3 days; P = .004) and were more likely to be discharged to hospice (56% vs 3.1%; P < .0001). Patients with IPCC were more likely to have a discharge code status of do not attempt resuscitation (89% vs 46%). There was no significant difference in comfort medications at discharge between groups.

CONCLUSIONS

Patients who received IPCC had evidence of more advanced dementia. These patients were more likely to change their code status and enroll in hospice. IPCC may be useful to prioritize patient-centered care and discuss what matters most to patients and families.
