Defining end of life in dementia: A systematic review

Does personality affect the cognitive decline in aging? A systematic review

Cognitive decline is a natural consequence of aging, but several genetic, environmental, and psychological factors can influence its trajectories. Among the most enduring factors, the Big Five personality traits - defined as relatively stable tendencies to think, behave, and react to the environment - can influence both directly (e.g., by physiological correlates) and indirectly (e.g., healthy or risky behaviors) the risk of developing dementia and mild cognitive impairment (MCI) - a preclinical form of cognitive decline. Despite the great amount of studies focusing on the relationship between personality and cognitive decline, an updated systematic synthesis of the results including a broader range of study designs is still lacking. This systematic review aims to summarize the findings of studies investigating: (i) differences in personality traits between groups of healthy individuals and those with MCI, (ii) the impact of personality traits on the risk for both MCI and dementia, and (iii) changes in personality traits among individuals progressing from normal cognition to MCI. Neuroticism emerged as a significant risk factor for MCI and dementia; Conscientiousness and Openness appear to offer protection against dementia and moderate cognitive decline. Overall, these findings suggest a pivotal role of personality structure in shaping cognitive outcomes on the long run.

Exploring the Regulatory Landscape of Dementia: Insights from Non-Coding RNAs

Dementia, a multifaceted neurological syndrome characterized by cognitive decline, poses significant challenges to daily functioning. The main causes of dementia, including Alzheimer's disease (AD), frontotemporal dementia (FTD), Lewy body dementia (LBD), and vascular dementia (VD), have different symptoms and etiologies. Genetic regulators, specifically non-coding RNAs (ncRNAs) such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are known to play important roles in dementia pathogenesis. MiRNAs, small non-coding RNAs, regulate gene expression by binding to the 3' untranslated regions of target messenger RNAs (mRNAs), while lncRNAs and circRNAs act as molecular sponges for miRNAs, thereby regulating gene expression. The emerging concept of competing endogenous RNA (ceRNA) interactions, involving lncRNAs and circRNAs as competitors for miRNA binding, has gained attention as potential biomarkers and therapeutic targets in dementia-related disorders. This review explores the regulatory roles of ncRNAs, particularly miRNAs, and the intricate dynamics of ceRNA interactions, providing insights into dementia pathogenesis and potential therapeutic avenues.

The burden of neurological conditions in north Africa and the Middle East, 1990-2019: a systematic analysis of the Global Burden of Disease Study 2019

BACKGROUND

The burden of neurological conditions in north Africa and the Middle East is increasing. We aimed to assess the changes in the burden of neurological conditions in this super-region to aid with future decision making.

METHODS

In this analysis of the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 data, we examined temporal trends of disability-adjusted life-years (DALYs; deaths and disabilities combined), deaths, incident cases, and prevalent cases of 14 major neurological conditions and eight subtypes in 21 countries in the north Africa and the Middle East super-region. Additionally, we assessed neurological DALYs due to 22 potentially modifiable risk factors, within four levels of classification, during the period 1990-2019. We used a Bayesian modelling estimation approach, and generated 95% uncertainty intervals (UIs) for final estimates on the basis of the 2·5th and 97·5th percentiles of 1000 draws from the posterior distribution.

FINDINGS

In 2019, there were 441·1 thousand (95% UI 347·2-598·4) deaths and 17·6 million (12·5-24·7) neurological DALYs in north Africa and the Middle East. The leading causes of neurological DALYs were stroke, migraine, and Alzheimer's disease and other dementias (hereafter dementias). In north Africa and the Middle East in 2019, 85·8% (82·6-89·1) of stroke and 39·9% (26·4-54·7) of dementia age-standardised DALYs were attributable to modifiable risk factors. North Africa and the Middle East had the highest age-standardised DALY rates per 100 000 population due to dementia (387·0 [172·0-848·5]), Parkinson's disease (84·4 [74·7-103·2]), and migraine (601·4 [107·0-1371·8]) among the global super-regions. Between 1990 and 2019, there was a decrease in the age-standardised DALY rates related to meningitis (-75·8% [-81·1 to -69·5]), tetanus (-88·2% [-93·9 to -76·1]), stroke (-32·0% [-39·1 to -23·3]), intracerebral haemorrhage (-51·7% [-58·2 to -43·8]), idiopathic epilepsy (-26·2% [-43·6 to -1·1]), and subarachnoid haemorrhage (-62·8% [-71·6 to -41·0]), but for all other neurological conditions there was no change. During 1990-2019, the number of DALYs due to dementias, Parkinson's disease, multiple sclerosis, ischaemic stroke, and headache disorder (ie, migraine and tension-type headache) more than doubled in the super-region, and the burden of years lived with disability (YLDs), incidence, and prevalence of multiple sclerosis, motor neuron disease, Parkinson's disease, and ischaemic stroke increased both in age-standardised rate and count. During this period, the absolute burden of YLDs due to head and spinal injuries almost doubled.

INTERPRETATION

The increasing burden of neurological conditions in north Africa and the Middle East accompanies the increasing ageing population. Stroke and dementia are the primary causes of neurological disability and death, primarily attributable to common modifiable risk factors. Synergistic, systematic, lifetime, and multi-sectoral interventions aimed at preventing or mitigating the burden are needed.

End-of-Life Care of Persons with Alzheimer's Disease and Other Dementias

End-of-life (EOL) care has been a common option for patients with terminal medical conditions such as cancers. However, the utilization of EOL care in Alzheimer disease and other dementing conditions have become available relatively recently. As the end-stage dementia approaches, the clinicians and caregivers become faced with numerous clinical challenges-delirium, neuropbehavioral symptoms, the patient's inability to communicate pain and associated discomfort, food refusal, and so on. In addition to providing quality clinical care to the EOL patients, clinicians should pay special attention to their families, assuring that their loved ones will receive supportive measures to improve quality of life (QOL).

Portuguese Caregivers of Persons With Alzheimer's Disease in the Context of the COVID-19 Pandemic: A Qualitative Study of the Grieving Process

This study addresses the experiences of informal caregivers caring for elderly family members with Alzheimer's disease (AD) during the COVID-19 pandemic. The study includes a sample of eight informal caregivers who were evaluated through a semi-structured interview six months after the death of a loved one they cared for. A thematic content analysis was applied to the interviews and yielded two higher-order domains: (1) Experiencing the AD and the death of a family member and (2) The grieving process during the COVID-19 pandemic. The results provide valuable insights into family caregivers' experiences regarding the profound emotional impact of caregiving and grief during the COVID-19 pandemic. Caregivers maintain their identity even after loss, underscoring the enduring impact of caregiving. The identity as a caregiver impacted coping and grief responses, highlighting the need for tailored interventions.

Music therapy for supporting informal carers of adults with life-threatening illness pre- and post-bereavement; a mixed-methods systematic review

BACKGROUND

Music therapy interventions with informal carers of individuals with life-threatening illness at pre- and post-bereavement is an increasingly important clinical area. This systematic review is the first to synthesise and critically evaluate the international evidence associated with music therapy with adult informal carers pre- and post-bereavement. Specifically, the objectives were: i) to describe the characteristics and effectiveness of music therapy interventions which aim to improve health-related outcomes for adult informal carers of adults with life-threatening illness (pre- and post-bereavement), and ii) to describe the experience of music therapy for adult informal carers of adults with life-threatening illness (pre- and post-bereavement).

METHODS

Eligibility: adult informal carers of adults at end of life or bereaved; music therapy interventions for improving health-related outcomes; qualitative; mixed-method; and quantitative studies including comparators of any other intervention; published in English from 1998 onwards. Six databases were searched up to July 2022. A JBI mixed-methods systematic review approach was followed throughout, including quality appraisal, data extraction and a convergent segregated approach to synthesis and integration.

RESULTS

A total of 34 studies were included, published between 2003 and 2022. Most were conducted in North America (n = 13), Australia (n = 10), or Europe (n = 8). No studies were conducted in low- and middle-income countries or in the UK. The majority were qualitative (n = 17), followed by quasi-experimental (n = 8), mixed-methods (n = 7) and two RCTs. The majority focused on carers of individuals with dementia (n = 21) or advanced cancer (n = 7). Seventeen studies were purely quantitative or included a quantitative component. During meta-synthesis, findings were aligned to core outcomes for evaluating bereavement interventions in palliative care and previously identified risk factors for complicated grief. Commonly targeted outcomes in quantitative studies included quality of life and mental wellbeing, showing equivocal effectiveness of music therapy with significant and non-significant results. Twenty-two studies either purely qualitative or with a qualitative component underwent meta synthesis and suggested a diverse range of improved pre- and post-bereavement outcomes for informal carers across all core outcomes, and across all risk and protective factors, including psychological, spiritual, emotional, and social outcomes.

CONCLUSIONS

Qualitative studies provide moderate to strong evidence for improved health-related outcomes for adult informal carers of adults with life-threatening illness pre-bereavement. Limited studies including those bereaved negates conclusions for the bereavement phase. Comparisons and explanations for effectiveness across quantitative and qualitative studies are equivocal, with a high risk of bias and small samples in the limited number of quantitative studies, demonstrating a need for high-quality RCTs.

Live Discharge of Hospice Patients with Alzheimer's Disease and Related Dementias: A Systematic Review

Background: Hospice is intended to promote the comfort and quality of life of dying patients and their families. When patients are discharged from hospice prior to death (ie, experience a "live discharge"), care continuity is disrupted. This systematic review summarizes the growing body of evidence on live discharge among hospice patients with Alzheimer's Disease and related dementias (ADRD), a clinical subpopulation that disproportionately experiences this often burdensome care transition. Methods: Researchers conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Reviewers searched AgeLine, APA PsycINFO (Ovid), CINAHL Plus with Full Text, ProQuest Dissertations & Theses Global, PubMed, Scopus, and Web of Science (Core Collection). Reviewers extracted data and synthesized findings from 9 records, which reported findings from 10 individual studies. Results: The reviewed studies, which were generally of high quality, consistently identified diagnosis of ADRD as a risk factor for live discharge from hospice. The relationship between race and live hospice discharge was less clear and likely dependent upon the type of discharge under investigation and other (eg, systemic-level) factors. Research on patient and family experiences underscored the extent to which live hospice discharge can be distressing, confusing, and associated with numerous losses. Conclusion: Research specific to live discharge among ADRD patients and their families is limited. Synthesis across included studies points to the importance for future research to differentiate between types of live discharge-revocation vsversus decertification-as these are vastly different experiences in choice and circumstances.

What care do people with dementia receive at the end of life? Lessons from a retrospective clinical audit of deaths in hospital and other settings

BACKGROUND

The need for better end-of-life care for people with dementia has been acknowledged. Existing literature suggests that people dying with dementia have less access to palliative care, yet little is known about the care provided to people with dementia at the end of life. This study aimed to establish evidence related to end-of-life care for people dying with dementia in hospital compared to other settings.

METHODS

A retrospective clinical audit of people who had a diagnosis of dementia and had accessed services within a local health district, who died between 2015 and 2019, was conducted. A total of 705 people were identified, and a subset of 299 people randomly selected for manual audit. Chi-square p-values were used to compare the place of death, and a t-test or non-parametric test was used to assess the significance of the difference, as appropriate. Measures of functional decline within one month of death were assessed using mixed effects logistic regression models.

RESULTS

The characteristics of people differed by place of death, with people who died in hospital more likely to be living at home and to not have a spouse. Less than 1 in 5 people had advance care directives or plans. Many were still being actively treated at the time of death: almost half of people who died in hospital had an investigation in their final 72 hours, less than half of people were coded as receiving palliative care at death, and more than 2 in 3 people did not get access to specialist palliative care. Declining function was associated with the terminal phase.

CONCLUSION

This study provides novel insights for those providing end-of-life care for people with dementia. Healthcare professionals and policy makers should consider how demographic characteristics relate to the places people with dementia receive end-of-life care. The care provided to people with dementia in the last year of their life highlights the need for more support to prepare advance care documentation and timely consideration for palliative care. Changes in markers of nutritional status and function in people with advanced dementia may help with identification of terminal phases.

Caregiver experiences of hospice dementia care: a systematic review and meta-ethnography

OBJECTIVES

Hospices are regarded as gold standard providers of end-of-life care. The term hospice, however, is broadly used, and can describe a type of care offered in a variety of health care services (e.g. nursing homes). It thus becomes complex for families to decide between services. We aimed to review the evidence around the experience of family carers of people with dementia accessing in-patient hospice settings for end-of-life care.

METHOD

We registered the review protocol on PROSPERO. We used PerSPE(C)TiF to systematically organise our search strategy. The evidence was reviewed across six databases: PubMed, EMBASE, PsycINFO, ASSIA, ISI Web, and CINAHL. We used meta-ethnography as per the eMERGe guidance for data interpretation.

RESULTS

Four studies were included. Two third-order constructs were generated through meta-ethnography: expectations of care and barriers to quality of care. We found that carers had expectations of care, and these could change over time. If discussion was not held with hospice staff early on, the carers could experience reduced care quality due to unmatched expectations. Unmatched expectations acted as barriers to care and these were found in terms of carers not feeling adequately supported, and/or having the person discharged from hospice, which would entail increased care responsibility for carers.

CONCLUSION

In view of an increase in new dementia cases over time and with hospice services being under pressure, integrating palliative care services within community-based models of care is key to reducing the risk of having inadequate and under resourced services for people with dementia.

End of Life Events and Causes of Death in Danish Long-Lived Siblings: Reduced Dementia Risk Compared to Sporadic Long-Livers

Background

Better physical robustness and resilience of long-lived siblings compared to sporadic long-livers has been demonstrated in several studies. However, it is unknown whether long-lived siblings also end their lives better.

Objective

To investigate end-of-life (EoL) events (dementia diagnosis, medication, hospitalizations in the last 5 years of life), causes of death, and location of death in long-lived siblings compared to matched sporadic long-livers from the Danish population.

Methods

Long-lived siblings were identified through three nationwide Danish studies in which the inclusion criteria varied, but 99.5% of the families had at least two siblings surviving to age 90 + . Those who died between 2006 and 2018 were included, and randomly matched with sex, year-of-birth and age-at-death controls (i.e., sporadic long-lived controls) from the Danish population.

Results

A total of 5,262 long-lived individuals were included (1,754 long-lived siblings, 3,508 controls; 63% women; median age at death 96.1). Long-lived siblings had a significantly lower risk of being diagnosed with dementia in the last years of life (p = 0.027). There was no significant difference regarding the number of prescribed drugs, hospital stays, days in hospital, and location of death. Compared to controls, long-lived siblings presented a lower risk of dying from dementia (p = 0.020) and ill-defined conditions (p = 0.030).

Conclusions

In many aspects long-lived siblings end their lives similar to sporadic long-livers, with the important exception of lower dementia risk during the last 5 years of life. These results suggest that long-lived siblings are excellent candidates for identifying environmental and genetic protective factors of dementia.

Supportive care decision-making processes of persons with dementia and their caregivers

Little is known about the decision-making processes around seeking more supportive care for dementia. Persons with dementia are often left out of decision-making regarding seeking more supportive care as their dementia progresses. This paper provides a description of findings from the Decision-making in Alzheimer's Research project (DMAR) investigating the process of decision-making about transitions to more supportive care. We conducted 61 qualitative interviews with two stakeholder groups: 24 persons with dementia, and 37 informal caregivers to explore supportive care decisions and associated decision-making factors from the perspectives of persons with dementia and their caregivers. We identified four main decisions that persons with dementia and their informal caregivers played a role in: (1) sharing household responsibilities; (2) limiting routine daily activities; (3) bringing in formal support; and (4) moving to a care facility. Based on our findings we developed a schematized roadmap of decision-making that we used to guide the discussion of our findings. Four crosscutting themes emerged from our analysis: unknowns and uncertainties, maintaining life as you know it, there's no place like home and resource constraints. These results will be incorporated into the development of instruments whose goal is to identify preferences of persons with dementia and their caregivers, in order to include persons with dementia in care decisions even as their dementia progresses.

Good death for people living with dementia: a qualitative study

BACKGROUND

Ensuring a good death is one of the primary objectives of palliative care and end-of-life care. There is insufficient evidence regarding what defines a good death for people living with dementia. Obtaining an understanding of what constitutes a good death could help improve dementia care. This study aimed to explore how multiple stakeholders perceive a good death for people living with dementia.

METHODS

This qualitative study was carried out across six prefectures in Japan. Enrollment of participants took place within dementia outpatient clinics, hospitals, daycare centers, and community centers. A total of thirty-three in-depth interviews with people living with dementia, physicians, and nurses were conducted. Six focus group discussions were performed with family caregivers and care workers. Verbatim transcripts of the interviews were prepared, and inductive content analysis was used to examine the data.

FINDINGS

Regarding the perception of a good death, the following themes were derived: (1) painless death; (2) dying in a preferred environment; (3) family's coping with loss; (4) maintaining regular life; (5) living with respect; and (6) preparation for death. All these themes are interrelated. Participants viewed a good death as a process rather than a single event.

CONCLUSION

This study identifies crucial components of a good death for people living with dementia. The findings could be used to improve dementia care.

Home-based care for people living with dementia at the end of life: the perspective of experts

BACKGROUND

In the last phase of their lives, people living with dementia often indicate restlessness, anxiety or pain. Further, their care is considered inadequate, as they are, for example, sometimes overtreated for curative care or undertreated for pain management. These patients also face multiple barriers in accessing palliative care. This qualitative study explores the perception of experts about how people living with dementia in Germany are cared for at home toward the end of their lives.

METHODS

A total of 12 experts involved in outpatient/palliative care were recruited to constitute a purposive, heterogeneous sample. Interviews, which were structured using an interview guide, were conducted with physicians, nurses, representatives of health insurance funds, welfare associations, municipal counselling centres, scientists and coordinators of outpatient palliative care and voluntary work; the interviews were transcribed and analysed via thematic content analysis, based on Kuckartz's method.

RESULTS

The analysis of the results led to the establishment of four main categories that focused on formal care arrangements, the roles of relatives in care arrangements, the specifics of dementia, and restrictions on access to palliative care.

CONCLUSIONS

Suitable end-of-life care for people living with dementia and support for their relatives require resources and the conceptualisation of specific care arrangements to help minimise potential barriers that prevent access to palliative care.

Dying with behavioral and psychological symptoms of dementia in Australian nursing homes: a retrospective case-control study

Objectives

To identify predictors of mortality in people with active and challenging behavioral and psychological symptoms of dementia (BPSD).

Design

A retrospective case-control study was designed to compare those referred to Dementia Support Australia (DSA) who died in the 12 months to November 2016, with an equal number of controls who did not die. An audit tool was designed after literature review and expert opinion from the service. Odds ratio calculations and the Mann-Whitney U test were used to assess for difference.

Setting

Residents of Australian residential aged care facilities with BPSD referred to the DSA service.

Participants

Of 476 patients referred to DSA during the study period, 44 died. 44 controls were randomly selected from those remaining matched for age and sex.

Results

Significant differences included higher rates of benzodiazepine use, drowsiness, delirium, reduced oral intake and discussions about goals of care in those who died. Those who died were referred to the service for a shorter period and had more frequent contact between DSA and nurses at the nursing homes. Increase in opioid use and loss of skin integrity in those who died approached significance. The overall end of life course demonstrated a complex set of needs with frequent delirium, pain and frailty.

Conclusion

Further study is required to determine the optimal care for those with BPSD at the end of their lives. This study would indicate complex end of life care needs and point to a role for palliative care support.

Accuracy of clinical predictions of prognosis at the end-of-life: evidence from routinely collected data in urgent care records

BACKGROUND

The accuracy of prognostication has important implications for patients, families, and health services since it may be linked to clinical decision-making, patient experience and outcomes and resource allocation. Study aim is to evaluate the accuracy of temporal predictions of survival in patients with cancer, dementia, heart, or respiratory disease.

METHODS

Accuracy of clinical prediction was evaluated using retrospective, observational cohort study of 98,187 individuals with a Coordinate My Care record, the Electronic Palliative Care Coordination System serving London, 2010-2020. The survival times of patients were summarised using median and interquartile ranges. Kaplan Meier survival curves were created to describe and compare survival across prognostic categories and disease trajectories. The extent of agreement between estimated and actual prognosis was quantified using linear weighted Kappa statistic.

RESULTS

Overall, 3% were predicted to live "days"; 13% "weeks"; 28% "months"; and 56% "year/years". The agreement between estimated and actual prognosis using linear weighted Kappa statistic was highest for patients with dementia/frailty (0.75) and cancer (0.73). Clinicians' estimates were able to discriminate (log-rank p < 0.001) between groups of patients with differing survival prospects. Across all disease groups, the accuracy of survival estimates was high for patients who were likely to live for fewer than 14 days (74% accuracy) or for more than one year (83% accuracy), but less accurate at predicting survival of "weeks" or "months" (32% accuracy).

CONCLUSION

Clinicians are good at identifying individuals who will die imminently and those who will live for much longer. The accuracy of prognostication for these time frames differs across major disease categories, but remains acceptable even in non-cancer patients, including patients with dementia. Advance Care Planning and timely access to palliative care based on individual patient needs may be beneficial for those where there is significant prognostic uncertainty; those who are neither imminently dying nor expected to live for "years".

End-of-life perspectives according to family caregivers of older adults with dementia: A qualitative study

BACKGROUND

Family caregivers are primarily responsible for the care of older adults with dementia, and the demands of this care increase as the end of life approaches. Experiencing the end of a family member's life can be stressful, and caregivers consider important to know how to identify when their loved one is approaching the end of life in order to prepare for this moment. Thus, as the family is primarily responsible for the older adult with dementia, it is essential to know the meanings of the end of life attributed by family caregivers.

OBJECTIVE

To analyze the perceptions of family caregivers of older adults with dementia about the end of life.

METHODS

This is a qualitative, descriptive and exploratory study. The convenience sample consisted of family caregivers of older adults with dementia. The inclusion criteria were being a family member directly involved in the care of the older adult with dementia and being 18 years of age or older. Data were collected from individual semi-structured interviews. The number of participants was defined during the interviews using the saturation criterion. Data were analyzed using the thematic analysis technique.

RESULTS

A total of 63 family caregivers participated, 74.6% of whom were women, predominantly wives and daughters. Two themes resulted from the data analysis: (i) Different perspectives on the end of life: from death itself to a sad, painful and long grief process; and (ii) End of life in the perspective of transcendence. The meaning of the end of life was perceived in different ways by family caregivers. Understanding how they perceive and experience the end-of-life process of the older adult with dementia helps to clarify the best ways for the health professionals to approach and intervene with these families.

Implementing Palliative Care Teams Specialized in Dementia in Two Countries: Experiences of Failure and Success

Much is known about palliative care needs of persons with dementia and their family. Less is known about how to successfully implement models that address those needs. We present specialist models in the Netherlands (2017-2018) and Northern Ireland (2016-2017) contrasting its evaluations. From implementation failure in the Netherlands compared with successful implementation in Northern Ireland, we learn that recognizing roles and competencies among all involved is essential in developing effective partnership relationships. All of this is facilitated by referral before the end of life and offering various training programs and in-patient and out-patient services and therapies to show benefits early.

Antiparasitic Activity of Hippeastrum Species and Synergistic Interaction between Montanine and Benznidazole against Trypanosoma cruzi

BACKGROUND

Hippeastrum species have a wide range of biological properties. In Argentina, this genus comprises ten widely distributed species.

PURPOSE

To evaluate the antiparasitic and anticholinesterase activities and chemical profiles of seven Argentinean Hippeastrum species and determine the synergism between the major isolated alkaloid-montanine-and benznidazole in anti-Trypanosoma cruzi activity.

METHODS

The antiparasitic activity was evaluated through antiproliferative and viability assays against T. cruzi epimastigotes. Synergism assays were performed using the Chou-Talalay method. AChE and BuChE inhibitory activities were also assessed. The alkaloid composition was obtained using GC-MS analysis.

RESULTS

All extracts showed strong growth inhibition of T. cruzi epimastigote proliferation. The extracts from H. aglaiae, H. aulicum, and H. hybrid stand out for their potent and total growth inhibition, which was comparable to benznidazole. The H. reticulatum extract showed strong Acetylcholinesterase (AChE) inhibitory activities, while five species showed moderate Butyrylcholinesterase (BuChE) inhibition. Fifteen alkaloids were identified by means of GC-MS. Regarding the synergism assessment, the highest synergistic effect was obtained from the combination of montanine and benznidazole.

CONCLUSION

Hippeastrum species bulb extracts from Argentina were shown to be a good source of antiparasitic alkaloids and cholinesterase inhibitors. The synergism between montanine and benznidazole emerges as a potential combination for future studies to treat Chagas disease.

Identification and Prognostication of End-of-Life State Using a Japanese Guideline-Based Diagnostic Method: A Diagnostic Accuracy Study

Purpose

Prognostic uncertainty can be a barrier to providing palliative care. Accurate prognostic estimation for patients at the end of life is challenging. This study aimed to evaluate the accuracy of end-of-life diagnosis using our unique diagnostic method.

Patients and Methods

A retrospective longitudinal observational study was conducted through collaboration among three medical facilities in a rural super-aged community in Japan. In 2007, we established a unique end-of-life diagnostic process comprising (1) physicians' judgement, (2) disclosure to patients, and (3) discussion at an end-of-life case conference (EOL-CC), based on Japanese end-of-life-related guidelines. Research subjects were consecutive patients discussed in EOL-CC between January 1, 2010, and September 30, 2017. The primary outcome was mortality within 6 months after the initial EOL-CC decision. Sensitivity, specificity, and diagnostic odds ratio were calculated using EOL-CC diagnosis (end-of-life or non-end-of-life) as an index test and overall survival (<6 months or ≥6 months) as a reference standard.

Results

In total, 315 patients were eligible for survival analysis (median age 89, range 54-107). The study population was limited to patients with severe conditions such as advanced cancer, organ failures, advanced dementia with severe deterioration in functioning. EOL-diagnosis by our methods was associated with much lower survival rate at 6 months after EOL-CC than non-EOL-diagnosis (6.9% vs 43.5%; P < 0.001). Of the patients, 297 were eligible for diagnostic accuracy analysis (median age 89, range 54-107). The EOL-diagnosis showed high sensitivity (0.95; 95% confidence interval [CI] 0.92-0.97) but low specificity (0.35; 95% CI 0.20-0.53) against the outcomes. It also showed a high diagnostic odds ratio (10.32; 95% CI 4.08-26.13).

Conclusion

The diagnostic process using the Japanese end-of-life guidelines had tolerable accuracy in identification and prognostication of end of life.

Health inequalities for older people from minority ethnic groups receiving palliative care and end of life care: A scoping review protocol

OBJECTIVE

The proposed scoping review aims to explore international literature on how older people from minority ethnic groups engage with and utilise palliative and end of life care, investigate the barriers and facilitators, and compare how this varies between ethnicities and health conditions.

INTRODUCTION

Minority ethnic groups make up substantial parts of the populations of many countries around the world. Research has found that there are disparities in access to palliative care and end of life care among minority ethnic groups. Language barriers, cultural values, and socio-demographic factors have been cited as preventing access to quality palliative and end of life care. However, it is unclear how these barriers and inequalities differ across different minority ethnic groups in different countries, and across different health conditions within these groups.

INCLUSION CRITERIA

The population will be older people of different minority ethnic groups who are receiving palliative or end of life care, family caregivers, and health and social care professionals. The sources of information will include quantitative, qualitative and mixed methods research, and sources that focus on minority ethnic groups' interactions with palliative and end of life care.

METHODS

A scoping review guided by the Joanna Briggs Institute Manual for Evidence Synthesis. Searches of MEDLINE, Embase, PsycInfo, CINAHL, Scopus, Web of Science, Assia, and the Cochrane Library will be conducted. Citation tracking, reference list checking and grey literature searches will be undertaken. Data will be extracted, charted and summarised descriptively.

IMPLICATIONS

This review will highlight the health inequalities present in palliative and end of life care, the research gaps in understudied minority ethnic populations, locations where further study is required, and how barriers and facilitators differ across different ethnic groups and health conditions. The results of this review will be shared with stakeholders and will provide evidence-based recommendations for inclusive palliative and end of life care.

A Review of Clinical Signs and Symptoms of Imminent End-of-Life in Individuals With Advanced Illness

Background: World population is not only aging but suffering from serious chronic illnesses, requiring an increasing need for end-of-life care. However, studies show that many healthcare providers involved in the care of dying patients sometimes express challenges in knowing when to stop non-beneficial investigations and futile treatments that tend to prolong undue suffering for the dying person. Objective: To evaluate the clinical signs and symptoms that show end-of-life is imminent in individuals with advanced illness. Design: Narrative review. Methods: Computerized databases, including PubMed, Embase, Medline,CINAHL, PsycInfo, and Google Scholar were searched from 1992 to 2022 for relevant original papers written in or translated into English language that investigated clinical signs and symptoms of imminent death in individuals with advanced illness. Results: 185 articles identified were carefully reviewed and only those that met the inclusion criteria were included for review. Conclusion: While it is often difficult to predict the timing of death, the ability of healthcare providers to recognize the clinical signs and symptoms of imminent death in terminally-ill individuals may lead to earlier anticipation of care needs and better planning to provide care that is tailored to individual's needs, and ultimately results in better end-of-life care, as well as a better bereavement adjustment experience for the families.

A Consensus Definition of End of Life from an International and Interdisciplinary Perspective: A Delphi Panel Study

Background: Those working in the field of palliative care have recognized that many terms are being used synonymously and that clear definitions (or any definitions) for many of these terms are lacking. The synonymous use of the terms palliative and end of life (EOL) can especially lead to conflicts in clinical practice, such as a tardy referral to palliative care. Such conflicts may then result in poorer treatment of patients, for instance, pain management. In research, the lack of clear definitions or even of any established definition for central concepts, such as EOL, weakens study validity and research outcomes. Objective: The aim of this study was to establish a concise definition for the EOL phase. Design: A modified Delphi study design was chosen. A structured questionnaire based on a previously conducted concept analysis about the EOL was used. Setting: A panel of international and interdisciplinary experts was established. Between 34 (1st round) and 21 (4th round) individuals participated in the anonymous online expert panel. Results: After four panel rounds, we were able to provide a definition which covers physical and psychosocial aspects that should be considered at the beginning of the EOL phase and possible predictions about the remaining time. The definition also covers aspects of EOL care, such as considerations related to the individual's dignity, spirituality, and maintenance of relationships. Conclusion: EOL is a term which is defined by considering multiple aspects that affect the process of identifying the EOL phase, the EOL phase itself and the resulting care options.

Gender differences in the intention to withhold life-sustaining treatments involving severe dementia for self and on behalf of parent or spouse

Background

Few studies have explored gender differences in the attitudes toward advanced care planning and the intention to withhold life-sustaining treatments (LSTs) involving severe dementia in Asian countries. We examined gender differences in the attitude toward the Patient Autonomy Act (PAA) in Taiwan and how the gender differences in these attitudes affect the intention to withhold LSTs for severe dementia. We also investigated self–other differences in the intention to withhold LSTs between genders.

Methods

Between March and October 2019, a structured questionnaire was distributed to hospitalized patients’ family members through face-to-face contact in an academic medical center. Exploratory factor analysis and independent and paired-sample t-tests were used to describe gender differences. Mediation analyses controlled for age, marital status, and education level were conducted to examine whether the attitude toward the PAA mediates the gender effect on the intention to withhold LSTs for severe dementia.

Results

Eighty respondents filled out the questionnaire. Exploratory factor analysis of the attitude toward the PAA revealed three key domains: regarding the PAA as (1) promoting a sense of abandonment, (2) supporting patient autonomy, and (3) contributing to the collective good. Relative to the men, the women had lower average scores for promoting a sense of abandonment (7.48 vs. 8.94, p = 0.030), higher scores for supporting patient autonomy (8.74 vs. 7.94, p = 0.006), and higher scores for contributing to the collective good (8.64 vs. 7.47, p = 0.001). Compared with the women, the men were less likely to withhold LSTs for severe dementia (15.84 vs. 18.88, p = 0.01). Mediation analysis revealed that the attitude toward the PAA fully mediated the gender differences in the intention to withhold LSTs for severe dementia. Both men and women were more likely to withhold LSTs for themselves than for their parents. Compared with the women, the men were more likely to withhold resuscitation for themselves than for their parents (p = 0.05). Women were more likely to agree to enteral tube feeding and a tracheotomy for their husbands than for themselves; men made consistent decisions for themselves and their wives in those LST scenarios.

Conclusion

Gender influences the attitude toward advanced care planning and consequently affects the intention to withhold LSTs, indicating that there may be a difference in how men and women perceive EOL decision-making for severe dementia in Taiwan. Further studies are warranted.

A feasibility study of a decision aid to support family carers of people with severe dementia or those towards the end-of-life

BACKGROUND

Advance care planning in dementia does not always happen. As dementia progresses, decisions are often left for family carers to make with professionals.

AIM

To test the feasibility and acceptability of the delivery and use of a decision aid for family carers of people with severe dementia or towards the end-of-life.

DESIGN

Feasibility study using a before-after design of a paper-based decision aid with family carers of people with severe dementia or towards the end-of-life. Criteria for whether to progress to full evaluation included achieving: 70% recruitment rate of target of 30 people, and retention of 70% at 6 months. Outcome measures at baseline, 3 and 6 months, included: the Decisional Conflict Scale (DCS), Kessler Psychological Distress Scale (K10), EQ5D-5L and Satisfaction with Care at the End of Life (SWC-EOLD).

PARTICIPANTS

Twenty-eight family carers were recruited (93% of target), 26 completed baseline assessment and 20 (71%) of those were followed-up at 6 months.

RESULTS

Almost all outcomes changed indicating improvement over 6 months. The DCS and K10 scores decreased indicating less decisional conflict and less psychological distress. The decision aid was acceptable, 25% found it very helpful and 55% a little helpful at 6 months.

CONCLUSION

We met the success criteria demonstrating this study was feasible and acceptable to carers. Future research should test the effectiveness of the decision aid in a full scale evaluation.

The German version of the Mini Suffering State Examination (MSSE) for people with advanced dementia living in nursing homes

Background

The Mini Suffering State Examination (MSSE) has been explicitly recommended to assess suffering in dementia patients. This study aimed to develop a German version of the MSSE and assess its psychometric properties involving people with advanced dementia (PAD) in a nursing home setting.

Methods

The MSSE was translated into German, and 95 primary nurses administered it cross-sectionally to 124 PAD in Zurich, Switzerland. The psychometric properties of the German MSSE version were calculated for this population.

Results

The mean age of the PAD was 83.3 years (SD = 9.1, range = 55–102 years), and 98 of them (79.0%) were women. The Kuder-Richardson Formula 20 coefficient for the entire scale (0.58), the eight items relating to objective health conditions (0.39), and the professional and family estimation of the patient’s suffering (0.64) indicated low internal consistency. A confirmatory factor analysis indicated an unsatisfactory fit to a one-factor structure, with a comparative fit index and root mean square error of approximation of 0.71 and 0.08, respectively, and a Tucker–Lewis index of 0.64. The MSSE total score was significantly but moderately correlated with the total scores of the Symptom Management–End-of-Life with Dementia (SM-EOLD) scale (Pearson’s correlation coefficient (r) = -0.44; p < 0.05), the physical suffering scores (r = 0.41; p < 0.05), and the psychological suffering scores (r = 0.55; p < 0.05).

Conclusions

The German version of the MSSE questionnaire did not perform well in the nursing home setting involving PAD. The instrument had low internal consistency, doubtful validity, and could not discriminate between suffering and other distressing symptoms. We do not recommend its use in this population.

Patterns of unplanned hospital admissions among people with dementia: from diagnosis to the end of life

BACKGROUND

hospitalisations are sentinel events for people with dementia. How patterns of unplanned hospital admissions change among people with dementia after diagnosis is relatively unknown.

OBJECTIVE

to describe patterns of unplanned hospital admissions of people with dementia from diagnosis until death/study end.

METHODS

retrospective cohort study using mental healthcare provider data of people diagnosed with dementia in London, UK (1995-2017), linked to mortality and hospital data. The primary outcome was the rate of unplanned hospital admissions after diagnosis until death/study end. We calculated the cumulative incidence of unplanned hospital admissions. The rates of unplanned hospital admissions and the percentage of time spent as an inpatient were stratified by time from first dementia diagnosis.

RESULTS

for 19,221 people with dementia (61.4% female, mean age at diagnosis 81.0 years (standard deviation, SD 8.5)), the cumulative incidence of unplanned hospital admissions (n = 14,759) was 76.8% (95% CI 76.3%-77.3%). Individuals remained in the study for mean 3.0 (SD 2.6) years, and 12,667 (65.9%) died. Rates and lengths of unplanned hospital admissions remained relatively low and short in the months after the dementia diagnosis, increasing only as people approached the end of life. Percentage of time spent as an inpatient was <3% for people who were alive at the study end but was on average 19.6 and 13.3% for the decedents in the last 6 and 12 months of life, respectively.

CONCLUSIONS

the steep rise in hospitalisations before death highlights the need for improved community care and services for people with dementia who are approaching the end of life.

The construction of the responsible patient in complex palliative care: interpreting palliative care policies

Background:

To contribute with knowledge to health policy development, this article presents a critical discourse analysis of two Norwegian official reports on palliative care published in 1999 and 2017.

Methods:

We identify, describe and discuss how linguistic features in policy documents contribute to and engender a distinct change from 1999 to 2017 in how patients are framed, documenting the development of palliative care.

Results:

The analysis identifies and considers two interwoven discourses: the discourse of accountability and the discourse of complexity. The patient moves from being described as in need of care, in the 1999 report, to being described as an active and responsible patient making proper choices, in the 2017 report.

Conclusion:

Result of this policy development might be less involvement of professionals and focus on existential questions, and more responsibility on patients for their prospective wellbeing and health: a change that we argue should be considered and counteracted in upcoming policy processes considering palliative care.

The last year of life for patients dying from cancer vs. non-cancer causes: a retrospective cross-sectional survey of bereaved relatives

PURPOSE

To compare health care experiences of patients with cancer or non-cancer diseases in their last year of life.

METHODS

A cross-sectional post-bereavement survey was conducted using an adapted German version of the VOICES questionnaire (VOICES-LYOL-Cologne). Differences in the reported experiences were assessed using a two-sided Pearson's chi-square test and Mann-Whitney U test.

RESULTS

We collected data from 351 bereaved relatives. More than half of non-cancer patients were not informed that their disease could lead to death (p < 0.001). When this was communicated, in 46.7% of non-cancer and 64.5% of cancer patients, it was reported by the hospital doctor (p = 0.050). In all, 66.9% of non-cancer and 41.6% of cancer patients were not informed about death being imminent (p < 0.001). On average, non-cancer patients had significantly fewer transitions and hospital stays in their last year of life (p = 0.014; p = 0.008, respectively). Non-cancer patients were treated more often by general practitioners, and cancer patients were treated more often by specialists (p = 0.002; p = 0.002, respectively). A substantially lower proportion of non-cancer patients were treated by at least one member of or in the setting of general or specialized palliative care (p < 0.001).

CONCLUSIONS

Non-cancer patients experience disadvantages in communication regarding their care and in access to specialized palliative care in their last year of life compared to cancer patients. Regarding the assessment of palliative care needs and the lack of communication of an incurable disease, non-cancer patients are underserved. An early identification of patients requiring palliative care is a major public health concern and should be addressed irrespective of diagnosis.

Multidisciplinary Clinicians and the Relational Autonomy of Persons with Neurodegenerative Disorders and an Advance Care Plan: A Thematic Analysis

Introduction

People diagnosed with neurodegenerative disorders often grapple with threats to their agency, prompting some to engage in advance care planning. Advance care plans are intended to protect autonomy by helping patients receive goal-consistent healthcare. Accordingly, there is a need to better understand factors associated with hospital doctors’ application of advance care plans to treatment decisions of this patient cohort.

Purpose

The purpose of this study was to explain the recommendations of multidisciplinary hospital-based clinicians about the benefits of advance care plans for people diagnosed with neurodegenerative disorders, and the elements that influence how doctors apply such plans.

Materials and Methods

Using a constructivist grounded theory informed thematic analysis, semi-structured interviews were conducted with purposively and theoretical sampled hospital-based clinicians: 16 doctors, six registered nurses and 10 allied health clinicians who self-reported having experience delivering healthcare to people with neurodegenerative disorders and an advance care plan. Allied health and nurse data helped to inform questions posed to doctors. Data were inductively analysed using open and focused coding.

Results

Analysis revealed two main themes: recommending agency through advance care plans; and limiting agency through advance care plans. These themes formed the basis of the core category: patient agency. All clinicians held positive attitudes towards advance care plans as a means to preserve patient voices and alleviate family of responsibility. However, the extent to which doctors shared decisions with family revealed a tension between individualistic agency associated with advance care plans and relational autonomy perceived by doctors as appropriate.

Conclusion

Although doctors expressed positive attitudes towards advance care plans, they typically practiced relational autonomy wherein they partner with family in contemporaneous healthcare decision on patients’ behalf. Accordingly, the healthcare preferences of hospitalised, incompetent people with neurodegenerative disorders are balanced against judgements of both doctors and family.

Challenges faced during the COVID-19 pandemic by family carers of people living with dementia towards the end of life

Background

People living with dementia account for a large proportion of deaths due to COVID-19. Family carers are faced with making significant and emotive decisions during the pandemic, including decisions about end of life. We aimed to explore the challenges faced by family carers of people living with dementia during the first wave of the COVID-19 pandemic in England, as reported by charity telephone support line staff, who were able to objectively discuss a range of different experiences of many different carers who call the helpline. In particular, we focussed on key concerns and areas of decision making at the end of life.

Methods

We conducted a qualitative study using semi-structured interviews with eight telephone support line staff from two UK based charities who support carers of people living with dementia and those at the end of life. Interviews were conducted in the first wave of the pandemic in England in May–June 2020.

Results

An overarching theme of uncertainty and reactivity during a crisis was identified, and within this, five main themes were identified: concerns about care transitions, uncertainty in engaging support and help, pandemic-motivated care planning, maintaining the wellbeing of the person living with dementia, and trust, loss of agency and confusion.

Conclusions

Family carers may be reluctant to seek support because of fear of what may happen to their relative, which may include hospitalisation and becoming ill with COVID-19, care home placement, or not being able to be with a relative at the end of life. In some cases, a lack of trust has developed, and instead carers are seeking support from alternative services they trust such as nationally known charities.This study was used to inform the development of a decision aid to support family carers making decisions about care for their relative with dementia during the pandemic, who the lack the capacity to make their own decisions.

Enteral tube feeding for people with severe dementia

BACKGROUND

The balance of benefits and harms associated with enteral tube feeding for people with severe dementia is not clear. An increasing number of guidelines highlight the lack of evidenced benefit and potential risks of enteral tube feeding. In some areas of the world, the use of enteral tube feeding is decreasing, and in other areas it is increasing.

OBJECTIVES

To assess the effectiveness and safety of enteral tube feeding for people with severe dementia who develop problems with eating and swallowing or who have reduced food and fluid intake.

SEARCH METHODS

We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE, Embase, four other databases and two trials registers on 14 April 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), or controlled non-randomised studies. Our population of interest was adults of any age with a diagnosis of primary degenerative dementia of any cause, with severe cognitive and functional impairment, and poor nutritional intake. Eligible studies evaluated the effectiveness and complications of enteral tube feeding via a nasogastric or gastrostomy tube, or via jejunal post-pyloric feeding, in comparison with standard care or enhanced standard care, such as an intervention to promote oral intake. Our primary outcomes were survival time, quality of life, and pressure ulcers.

DATA COLLECTION AND ANALYSIS

Three review authors screened citations and two review authors assessed full texts of potentially eligible studies against inclusion criteria. One review author extracted data, which were then checked independently by a second review author. We used the 'Risk Of Bias In Non-randomised Studies of Interventions' (ROBINS-I) tool to assess the risk of bias in the included studies. Risk of confounding was assessed against a pre-agreed list of key potential confounding variables. Our primary outcomes were survival time, quality of life, and pressure ulcers. Results were not suitable for meta-analysis, so we presented them narratively. We presented results separately for studies of percutaneous endoscopic gastrostomy (PEG) feeding, nasogastric tube feeding and studies using mixed or unspecified enteral tube feeding methods. We used GRADE methods to assess the overall certainty of the evidence related to each outcome for each study.

MAIN RESULTS

We found no eligible RCTs. We included fourteen controlled, non-randomised studies. All the included studies compared outcomes between groups of people who had been assigned to enteral tube feeding or oral feeding by prior decision of a healthcare professional. Some studies controlled for a range of confounding factors, but there were high or very high risks of bias due to confounding in all studies, and high or critical risks of selection bias in some studies. Four studies with 36,816 participants assessed the effect of PEG feeding on survival time. None found any evidence of effects on survival time (low-certainty evidence). Three of four studies using mixed or unspecified enteral tube feeding methods in 310 participants (227 enteral tube feeding, 83 no enteral tube feeding) found them to be associated with longer survival time. The fourth study (1386 participants: 135 enteral tube feeding, 1251 no enteral tube feeding) found no evidence of an effect. The certainty of this body of evidence is very low. One study of PEG feeding (4421 participants: 1585 PEG, 2836 no enteral tube feeding) found PEG feeding increased the risk of pressure ulcers (moderate-certainty evidence). Two of three studies reported an increase in the number of pressure ulcers in those receiving mixed or unspecified enteral tube feeding (234 participants: 88 enteral tube feeding, 146 no enteral tube feeding). The third study found no effect (very-low certainty evidence).  Two studies of nasogastric tube feeding did not report data on survival time or pressure ulcers. None of the included studies assessed quality of life. Only one study, using mixed methods of enteral tube feeding, reported on pain and comfort, finding no difference between groups. In the same study, a higher proportion of carers reported very heavy burden in the enteral tube feeding group compared to no enteral tube feeding. Two studies assessed the effect of nasogastric tube feeding on mortality (236 participants: 144 nasogastric group, 92 no enteral tube feeding). One study of 67 participants (14 nasogastric, 53 no enteral tube feeding) found nasogastric feeding was associated with increased mortality risk. The second study found no difference in mortality between groups. The certainty of this evidence is very low. Results on mortality for those using PEG or mixed methods of enteral tube feeding were mixed and the certainty of evidence was very low. There was some evidence from two studies for enteral tube feeding improving nutritional parameters, but this was very low-certainty evidence. Five studies reported a variety of harm-related outcomes with inconsistent results. The balance of evidence suggested increased risk of pneumonia with enteral tube feeding. None of the included studies assessed behavioural and psychological symptoms of dementia.

AUTHORS' CONCLUSIONS

We found no evidence that tube feeding improves survival; improves quality of life; reduces pain; reduces mortality; decreases behavioural and psychological symptoms of dementia; leads to better nourishment; improves family or carer outcomes such as depression, anxiety, carer burden, or satisfaction with care; and no indication of harm. We found some evidence that there is a clinically significant risk of pressure ulcers from enteral tube feeding. Future research should focus on better reporting and matching of control and intervention groups, and clearly defined interventions, measuring all the outcomes referred to here.
