The Ethics of Life and Death: Advance Directives and End-of-Life Decision Making in Persons with Dementia

Relating to the end of life through advance care planning: Expectations and experiences of people with dementia and their family caregivers

Background

Dementia is widely considered a progressive condition associated with changes in cognitive capacities, which promotes the idea that people with dementia need to anticipate end-of-life care preferences. There is a growing body of interventions meant to support advance care planning (ACP) for people with dementia and their families. However, a deeper understanding of their experiences and expectations regarding planning the end of life is needed to inform ethically sound and person-centered ACP. This study explores how end-of-life care planning for people with dementia is experienced and perceived in practice.

Methods

We conducted a secondary analysis of qualitative data from in-depth interviews and ethnographic fieldwork. Participants included people with dementia living in the community or in nursing homes, family caregivers, and professional caregivers. During reflective sessions, the researchers moved back and forth between their original data and overarching topics related to ACP. Both performed deductive coding to filter relevant information from their data. Ongoing discussions allowed for the fine-tuning of themes.

Results

End-of-life care planning for people with dementia can encompass a paradox of control. While it may foster a sense of being in control, it may also feel like relinquishing control over future situations. It raises concerns regarding responsibility, as present, former and future wishes may not align. Family caregivers are often responsible for concrete end-of-life decision-making, prompting them to weigh previous wishes against present situations. Further, people with dementia may wish to focus on the present and distance themselves from the future.

Discussion

Advance decisions about end-of-life care are often decontextualized and people may find it difficult to oversee their future conditions and preferences. The widely recognized purpose of ACP to exert control over end-of-life care may need revision to match the needs of people with dementia while they are coping with their condition and an uncertain future.

Health Outcome Prioritization in Alzheimer's Disease: Understanding the Ethical Landscape

BACKGROUND

Dementia has been described as the greatest global health challenge in the 21st Century on account of longevity gains increasing its incidence, escalating health and social care pressures. These pressures highlight ethical, social, and political challenges about healthcare resource allocation, what health improvements matter to patients, and how they are measured. This study highlights the complexity of the ethical landscape, relating particularly to the balances that need to be struck when allocating resources; when measuring and prioritizing outcomes; and when individual preferences are sought.

OBJECTIVE

Health outcome prioritization is the ranking in order of desirability or importance of a set of disease-related objectives and their associated cost or risk. We analyze the complex ethical landscape in which this takes place in the most common dementia, Alzheimer's disease.

METHODS

Narrative review of literature published since 2007, incorporating snowball sampling where necessary. We identified, thematized, and discussed key issues of ethical salience.

RESULTS

Eight areas of ethical salience for outcome prioritization emerged: 1) Public health and distributive justice, 2) Scarcity of resources, 3) Heterogeneity and changing circumstances, 4) Knowledge of treatment, 5) Values and circumstances, 6) Conflicting priorities, 7) Communication, autonomy and caregiver issues, and 8) Disclosure of risk.

CONCLUSION

These areas highlight the difficult balance to be struck when allocating resources, when measuring and prioritizing outcomes, and when individual preferences are sought. We conclude by reflecting on how tools in social sciences and ethics can help address challenges posed by resource allocation, measuring and prioritizing outcomes, and eliciting stakeholder preferences.

Philosophical issues in dementia

PURPOSE OF REVIEW

This review aims to consider the philosophical literature from the last 18 months relevant to dementia. Philosophical thought should underpin and strengthen developments in clinical practice. For instance, deepening our thoughts about personhood should support the development of person-centred care.

RECENT FINDINGS

There is relatively little work written by philosophers about dementia. But much of the writing by health and social care researchers and much empirical work in this field throws up philosophical issues. These do not solely concern personal identity, personhood and selfhood, even if the literature frequently refers to these topics. Instead we see, first, that there are other issues (around citizenship, rights, the nature of mind, of normality and of ageing) which deserve further philosophical attention and, secondly, that the discussions about personhood have moved beyond the concern that our persistence over time as individuals depends on memory to encompass a broader view which emphasizes instead the ability of people to continue to construct their life-worlds through their persisting meaningful relationships.

SUMMARY

Real interaction with people with dementia creates an increasingly nuanced account of the life-worlds of people with dementia, which should stimulate both philosophical work and clinical practice.
