Dementia Care at End of Life: Current Approaches

Cognitive biases and moral characteristics of healthcare workers and their treatment approach for persons with advanced dementia in acute care settings

Introduction

Palliative care (PC) delivery for persons with advanced dementia (AD) remains low, particularly in acute-care settings. Studies have shown that cognitive biases and moral characteristics can influence patient care through their effect on the thinking patterns of healthcare workers (HCWs). This study aimed to determine whether cognitive biases, including representativeness, availability, and anchoring, are associated with treatment approaches, ranging from palliative to aggressive care in acute medical situations, for persons with AD.

Methods

Three hundred fifteen HCWs participated in this study: 159 physicians and 156 nurses from medical and surgical wards in two hospitals. The following questionnaires were administered: a socio-demographic questionnaire; the Moral Sensitivity Questionnaire; the Professional Moral Courage Scale; a case scenario of a person with AD presenting with pneumonia, with six possible interventions ranging from PC to aggressive care (referring to life-prolonging interventions), each given a score from (-1) (palliative) to 3 (aggressive), the sum of which is the "Treatment Approach Score;" and 12 items assessing perceptions regarding PC for dementia. Those items, the moral scores, and professional orientation (medical/surgical) were classified into the three cognitive biases.

Results

The following aspects of cognitive biases were associated with the Treatment Approach Score: representativeness-agreement with the definition of dementia as a terminal disease and appropriateness of PC for dementia; availability-perceived organizational support for PC decisions, apprehension regarding response to PC decisions by seniors or family, and apprehension regarding a lawsuit following PC; and anchoring-perceived PC appropriateness by colleagues, comfort with end-of-life conversations, guilt feelings following the death of a patient, stress, and avoidance accompanying care. No association was found between moral characteristics and the treatment approach. In a multivariate analysis, the predictors of the care approach were: guilt feelings about the death of a patient, apprehension regarding senior-level response, and PC appropriateness for dementia.

Conclusion

Cognitive biases were associated with the care decisions for persons with AD in acute medical conditions. These findings provide insight into the potential effects of cognitive biases on clinical decisions, which may explain the disparity between treatment guidelines and the deficiency in the implementation of palliation for this population.

Euthanasia in persons with advanced dementia: a dignity-enhancing care approach

In current Western societies, increasing numbers of people express their desire to choose when to die. Allowing people to choose the moment of their death is an ethical issue that should be embedded in sound clinical and legal frameworks. In the case of persons with dementia, it raises further ethical questions such as: Does the person have the capacity to make the choice? Is the person being coerced? Who should be involved in the decision? Is the person's suffering untreatable? The use of Advance Euthanasia Directives (AED) is suggested as a way to deal with end-of-life wishes of persons with dementia. However, in the Netherlands-the only country in which this practice is legal-the experiences of patients, doctors, and relatives have been far from satisfactory.Our paper analyses this complex ethical challenge from a Dignity-Enhancing Care approach, starting from the Dutch experiences with AED as a case. We first consider the lived experiences of the different stakeholders, seeking out a dialogical-interpretative understanding of care. We aim to promote human dignity as a normative standard for end-of-life care practices. Three concrete proposals are then presented in which this approach can be operationalised in order to deal respectfully with the end-of-life choices of persons with dementia.

Junior medical doctors' decision making when using advance care directives to guide treatment for people with dementia: a cross-sectional vignette study

Background

Junior medical doctors have a key role in discussions and decisions about treatment and end-of-life care for people with dementia in hospital. Little is known about junior doctors’ decision-making processes when treating people with dementia who have advance care directives (ACDs), or the factors that influence their decisions. To describe among junior doctors in relation to two hypothetical vignettes involving patients with dementia: (1) their legal compliance and decision-making process related to treatment decisions; (2) the factors influencing their clinical decision-making; and (3) the factors associated with accurate responses to one hypothetical vignette.

Method

A cross-sectional survey of junior doctors, including trainees, interns, registrars and residents, on clinical rotation in five public hospitals located in one Australian state. The anonymous, investigator-developed survey was conducted between August 2018 and June 2019. Two hypothetical vignettes describing patients with dementia presenting to hospital with an ACD and either: (1) bacterial pneumonia; or (2) suspected stroke were presented in the survey. Participants were asked to indicate whether they would commence treatment, given the ACD instructions described in each vignette.

Results

Overall, 116 junior doctors responded (35% consent rate). In Vignette 1, 58% of respondents (n = 67/116) selected the legally compliant option (i.e. not commence treatment). Participants who chose the legally compliant option perceived ‘following patient wishes’ (n = 32/67; 48%) and ‘legal requirements to follow ACDs’ (n = 32/67; 48%) as equally important reasons for complying with the ACD. The most common reason for not selecting the legally compliant option in Vignette 1 was the ‘ACD is relevant in my decision-making process, but other factors are more relevant’ (n = 14/37; 38%). In Vignette 2, 72% of respondents (n = 83/116) indicated they would commence treatment (i.e. not follow the ACD) and 18% (n = 21/116) selected they would not commence treatment. (i.e. follow the ACD). Similar reasons influenced participant decision-making in Vignette 2, a less legally certain scenario.

Conclusions

There are critical gaps in junior doctors’ compliance with the law as it relates to the implementation of ACDs. Despite there being differences in relation to the legal answer and its certainty, clinical and ethical factors guided decision-making over and above the law in both vignettes. More education and training to guide junior doctors’ clinical decision-making and ensure compliance with the law is required.

Effect of providing purple sweet potato water extract on tumor necrosis factor-α levels, protein 53 expression, glial fibrillary acidic protein expression, brain-derived neurotrophic factor levels, and spatial working memory in rats with d-galactose induction

Alzheimer's dementia (AD) is a neurodegenerative disease. The mechanism of oxidative stress in AD is due to amyloid beta (Aβ) protein that aggregates to form plaques, which further triggers chronic inflammation and neuronal apoptosis. Purple sweet potato extract with the main content of anthocyanins is a potential antioxidant with a direct target on the amyloid cascade hypothesis.

Objective

The research objective was to determine the role of purple sweet potato water extract as an antioxidant and anti-inflammatory in preventing apoptosis in order to provide a neuroprotective effect in d-galactose-induced rats.

Methods

A total of 100 male Wistar rats with randomized posttest-only control group design that met the eligibility criteria were included in this study. The treatment group was given 200 mg/kg BW/day of purple sweet potato water extract on days 1-70. d-galactose induction was administered in the treatment and control groups on days 15-70.

Results

The independent t-test showed that the mean tumor necrosis factor-α (TNF-α) levels in the treatment group (735.36±139.74) was significantly lower than that in the control group (896.77±152.52). The p53 and glial fibrillary acidic protein (GFAP) expressions of astrocyte cells in the treatment group were significantly lower than that in the control group. The brain-derived neurotrophic factor (BDNF) levels in the treatment group (498.13±121.47) were higher than that in the control (391.93±140.28), and there was a significant increase in spatial working memory in the treatment group (72.01±10.22) than the control (59.77±11.87).

Conclusions

The neuroprotective effect of purple sweet potato extract is due to d-galactose induction resulting from decrease in TNF-α levels, p53 expression, and GFAP expression and increase in BDNF levels and spatial working memory.

Practitioner Bias as an Explanation for Low Rates of Palliative Care Among Patients with Advanced Dementia

Patients with advanced dementia are less likely than those with other terminal illnesses to receive palliative care. Due to the nature and course of dementia, there may be a failure to recognize the terminal stage of the disease. A possible and under-investigated explanation for this healthcare disparity is the healthcare practitioner who plays a primary role in end-of-life decision-making. Two potential areas that might impact provider decision-making are cognitive biases and moral considerations. In this analysis, we demonstrate how the cognitive biases and moral considerations of practitioners related to clinical decision-making are inherent in clinical practice and may impact on providers' accuracy related to diagnostic and treatment related decision-making associated with patients with advanced dementia. Anchoring, default, availability, representativeness and framing biases are cognitive biases based on the "Two System Model" that relate to decision-making in end-of-life care. In patients with advanced dementia, those biases may result in a tendency to adhere to traditional mandatory care, involving an aggressive approach to care, which values saving lives at all costs, without taking into account the possible suffering and long-term consequences. Aspects such as moral sensitivity and moral courage play an important role in ethical decision-making related to advanced dementia. Investigations of clinical decision-making that include the cognitive biases and ethical considerations of practitioners might advance the comprehensive understanding of the clinical decision-making process related to care of patients with advanced dementia and promote the quality of care given to this population.

Accuracy of two prognostic indexes to predict mortality in older adults with advanced dementia

Dementia is a cause of disability among older adults. Accessing advanced dementia prognosis is a challenge.

Euthanasia in Dementia: A Narrative Review of Legislation and Practices in the Netherlands and Belgium

Euthanasia was first legalized in the Netherlands and Belgium in 2001 and 2002, respectively. Currently they are among the few countries that also allow euthanasia on the basis of dementia, which is still considered controversial, both from a scientific and societal perspective. To date, euthanasia in dementia constitutes a small proportion of all Dutch and Belgian euthanasia cases. However, instances are rising due to a growing awareness among the general public about the possibilities of a self-chosen end-of-life and the willingness among medical professionals to perform euthanasia in individuals diagnosed with dementia. In both countries euthanasia is allowed under strict conditions in patients with dementia and decisional capacity regarding euthanasia, while in the Netherlands an advance euthanasia directive can also replace an oral request for euthanasia in those with late-stage dementia. Judging euthanasia requests from patients with dementia is complex and the assessment of the due care criteria (especially those related to decisional capacity and unbearable suffering) requires caution and great care. In this narrative review, we reflect on the legal regulation, clinical guidelines and societal debate regarding euthanasia in dementia in the Netherlands and Belgium. By discussing the 20 years of experience with the ethical dilemmas and controversial aspects surrounding this delicate topic, we hope to inform the preparation or implementation of new legislation on euthanasia in dementia in other countries.

Caring for Patients With Dementia at End of Life

Care of the dementia patient continues to be challenging. It is a terminal condition that many times goes undiagnosed leading to improper evidence-based interventions. Healthcare professionals (HCPs) should initiate goals of care conversations early with patients and their families in order to align treatment preferences. Early integration of palliative medicine is an important intervention that can lead to better manage symptoms and lessen the strain on loved ones. Additionally, early enrollment into hospice should be encouraged with loved ones to promote quality of life as defined by the patient.

Towards personalized dementia care through meaningful activities supported by technology: A multisite qualitative study with care professionals

BACKGROUND

Person-centred care is widely recognised as important for helping people with dementia maintain a sense of self and purpose in life - especially for those living in care facilities. Despite this, most care practices still adopt a medical approach in which physical needs are prioritized over psychosocial well-being. Addressing the need to find ways of promoting person-centred approaches in care, this study explored care professionals' reflections on a novel, technological intervention (SENSE-GARDEN) that combines multisensory stimuli and digital media to create personalized environments for people with dementia. The aim of this study was to explore the experiences of care professionals who had used SENSE-GARDEN for approximately 1 year.

METHODS

Three care homes in Norway, Belgium, and Portugal and 1 hospital in Romania used the SENSE-GARDEN with residents/patients with moderate to severe dementia over the course of 1 year. Qualitative data - including observations and interviews with 2 care professionals - were collected at the beginning of the study period from the Norwegian care home to explore initial impressions of the new SENSE-GARDEN room. At the end of the study period, 8 care professionals across the 4 facilities were interviewed for an in-depth exploration of their experiences. The two sets of data were analysed separately through reflexive thematic analysis.

RESULTS

At the beginning of the study period, the staffs' focus was mainly on the novelty of the new SENSE-GARDEN room and how it provided opportunities for meaningful experiences. Post-intervention, the care professionals provided reflective accounts on how care could be delivered in alternative ways to standard practice. The themes generated from the post-intervention interviews were: "shifting focus onto personalized care", "building and fostering relationships", and "continuous discoveries". Through delivering person-centred care, the professionals reported a sense of purpose and achievement in their work.

CONCLUSIONS

Professionals from care facilities across 4 different countries highlighted the value of interventions such as SENSE-GARDEN as a way of creating opportunities to better know people with dementia. Thus, they experienced improved relationships and greater job satisfaction. However, delivering person-centred interventions is time-consuming, and future research should evaluate the feasibility of sustaining them on a long-term basis.

Activities of daily living at hospital admission associated with mortality in geriatric patients with dementia: a Danish nationwide population-based cohort study

PURPOSE

Determining life expectancy in patients with dementia are challenging. We aimed at studying the association between basic activities of daily living as measured by the Barthel Index at hospital admission and mortality among older patients with dementia.

METHODS

All patients aged ≥ 65 years with diagnosed dementia in the population-based National Danish Geriatric Database from 2005 to 2014 were included and followed until death, emigration, or study termination (31.12.2015). Data on Barthel Index (BI) were used to assess ADL. Patients were categorized into four predefined standard BI subcategories according to the national Danish version of the statistical classification of diseases [BI = 0-24 (very low ADL), BI = 25-49 (low ADL), BI = 50-79 (moderate reduced ADL), and BI = 80-100 (independent ADL)]. Association with mortality was assessed using multivariable Cox regression analysis adjusting for age, marital status, Charlson Comorbidity Index, BMI, prior hospitalizations, year of admission and polypharmacy.

RESULTS

In total, 6550 patients (women 62%) were included, median (IQR) age 84 (79-88) years and BI 37 (13-63). Mortality increased significantly with decreasing BI in both the crude and multivariable analysis. In subcategories BI = (80-100) and BI = (0-24), survival time (median (95%)) was 3.6 (3.4-3.9) years and 0.8 (0.7-0.9) years, respectively. Also, in patients with BI = (0-24), the overall mortality risk (HR (95% CI)) was 2.5 (2.2-2.8), 30-day risk 11.8 (5.8-23.9), and 1-year risk 4.4 (3.6-5.5) when using BI = (80-100) as reference.

CONCLUSION

Barthel Index is independently associated with all-cause mortality among older patients with dementia admitted to hospital. BI may be a helpful tool for clinicians when discussing treatment and care strategies with patients and their families.

Los cuidados paliativos domiciliares reducen las consultas a urgencias y muertes en centros de salud a un menor costo

Resumen Objetivos Comparar los tipos de asistencia domiciliar geriátrica y paliativa para determinar cuál obtiene mejores resultados en los pacientes con demencia avanzada. Métodos El presente es un estudio de cohorte retrospectiva. Se incluyeron pacientes con demencia avanzada ingresados al programa de Atención Comunitaria Geriátrica de un hospital geriátrico público de Costa Rica en el periodo entre enero de 2018 y junio de 2019. Ellos se dividieron en dos grupos dependiendo del equipo especializado que realizó la atención domiciliaria y se analizaron sus características sociodemográficas y clínicas. Posteriormente, se analizaron los datos generados de los registros médicos sobre consultas de emergencia, hospitalización, lugar de defunción y costo de la visita generados por cada paciente entre junio de 2018 y diciembre de 2019. Se compararon 192 pacientes con demencia avanzada Global Dementia Scale 7 visitados por el equipo geriátricos especializado domiciliar con 19 de visitados por el equipo de cuidados paliativos especializado domiciliar del Hospital Geriátrico Nacional. Resultados Se analizaron 226 datos generados (192 por el programa de geriatría y 34 por el de paliativos). Los que recibían atención domiciliaria por un equipo paliativo tenían menos probabilidades de acudir a la sala de emergencias y morir en un centro de salud en comparación con aquellos que reciben atención domiciliaria por un equipo geriátrico, con un costo menor. Conclusiones El programa de cuidado paliativo especializado domiciliar reduce las consultas de emergencia, la muerte en el domicilio y los costos de atención en pacientes con demencia avanzada en comparación con el programa geriátrico.

Challenges related to providing care for parents with dementia across borders: A qualitative study on transnational carers in Oslo

Migration requires people to re-define their caring roles, develop new caring strategies and negotiate the scope of care with the family in the country of origin. The main aim of this paper is to identify and describe challenges related to transnational care provided for people with dementia. Transnational caring itself poses many challenges for families but caring for a person living with dementia can be especially difficult. The qualitative data presented in this article was collected in 2018 as part of a larger study focusing on understandings, experiences and responses to age-related cognitive impairment among families with minority ethnic backgrounds. The data includes seven semi-structured in-depth interviews with migrants in Oslo who were engaged in transnational caring activities for their parents living with dementia. The participants in our study experienced numerous challenges related to providing care across borders to their parents. Some of the challenges were typical for transnational caring and were associated with care regimes in the countries of parents' and participants' residence, motives for providing care, participants' socio-economic situation and family relations. The other challenges were due to specific care needs of people living with dementia.

"It is always me against the Norwegian system." barriers and facilitators in accessing and using dementia care by minority ethnic groups in Norway: a qualitative study

BACKGROUND

Dementia is one of the greatest health challenges in the contemporary world. Due to several barriers to accessing health care services, elderly immigrants constitute a group that poses special challenges in dementia diagnosis and treatment. The aim of this study was to explore the barriers and facilitators in accessing and using dementia care services by minority ethnic groups in Norway.

METHODS

The study utilised a qualitative design. The participants included family caregivers of individuals from minority ethnic groups living with dementia, representatives of immigrant communities, and representatives of health and care personnel working with people living with dementia. Individual semi-structured in-depth interviews were carried out in 2018 and 2019 in Oslo and Akershus. Interviews were analysed using thematic analyses.

RESULTS

Several barriers and facilitators in accessing and using dementia care services were identified, the most important of which were related to lack of knowledge of dementia, lack of awareness of dementia care services, lack of language skills, culturally based differences, the organisation of Norwegian dementia care services, and immigrants' socio-economic status. According to the study participants, having health care personnel in the family and further adaptation of dementia services to the needs of people with different cultural and linguistic backgrounds facilitate access to dementia services.

CONCLUSIONS

The study shows the need to develop inclusive policies that promote a patient-centred approach to ensure that individuals from minority ethnic groups receive appropriate dementia care.

Comfort and Satisfaction With Care of Home-Dwelling Dementia Patients at the End of Life

CONTEXT

Despite the preference to pass away at home, many dementia patients die in institutions, resulting in a paucity of studies examining end-of-life care outcomes in the home setting.

OBJECTIVE

The objective of this study was to identify modifiable factors associated with the comfort of dementia patients dying at home and families' satisfaction with care.

METHODS

This is a prospective cohort study conducted from October 2014 to April 2019 in Singapore. Dementia patients at Stage 7 on the Functional Assessment Staging Scale, with albumin <35 g/L, enteral feeding, or pneumonia, were recruited from a palliative homecare program. Independent variables included demographics, medical information, and care preferences. The Comfort Assessment in Dying with Dementia scale assessed dying patients' comfort, whereas the Satisfaction with Care at the End-of-Life in Dementia scale evaluated family caregivers' satisfaction two months after bereavement. Gamma regression identified factors independently associated with comfort and satisfaction.

RESULTS

The median age of 202 deceased patients whose comfort was assessed was 88 years. Anti-cholinergic prescription (60.4% of patients) [β (95% CI) = 1.823 (0.660-2.986), P = 0.002] was positively associated with comfort, whereas opioid prescription (89.6%) [β (95% CI) = -2.179 (-4.107 to -0.251), P = 0.027] and >1 antibiotic courses used in the last two weeks of life (77.2%) [β (95% CI) = -1.968 (-3.196 to -0.740), P = 0.002] were negatively associated. Independent factors associated with families' satisfaction with care were comfort [β (95% CI) = 0.149 (0.012-0.286), P = 0.033] and honoring of medical intervention preferences (96.0%) [β (95% CI) = 3.969 (1.485-6.453), P = 0.002].

CONCLUSION

Achieving comfort and satisfaction with care for dementia patients dying at home involves an interplay of modifiable factors. Honoring medical intervention preferences, such as those with palliative intent associated with patients' comfort, determined families' satisfaction with care.

Expert Consensus on the Care and Management of Patients with Cognitive Impairment in China

The cognitive disease consensus was prepared by panels of health and public representatives based on actual clinical practice in Geriatric Departments in Chinese hospitals and a systematic literature review. This consensus reflects the medical knowledge accumulated by those experts and provides information about professional medical care and advice. A multidisciplinary panel of specialists (neurologists, psychiatrists, and nursing specialists) reports an expert consensus on the medical knowledge accumulated from those experts and provides information about professional medical care and advice. The recommendations focus on the care and management of older adults with mild cognitive impairment, the objectives and methods of maintaining cognition and training, the assessments and measures of daily care for patients at different stages of dementia, the assessments and coping strategies for the behavioral and psychological symptoms of dementia, principles and suggestions for an appropriate living environment, arrangements for recreational activities, the care and management of patients with end-stage dementia, and suggestions for addressing stress in caregivers.

Palliative Care for Dementia: 2020 Update

Dementia management is complicated by neuropsychiatric symptoms such that the longitudinal care of a psychiatrist or other mental health provider is often an essential part of patient care and a major source of family support. Given the importance of end-of-life continuity of care, the involvement of psychiatry in palliative and hospice services affords an important opportunity for growth. Common challenges involve sharing prognostic information with patients and families to aid in advance planning, and management of persistent pain and nutritional issues. Future research will yield important new insights and guidelines for care.
