The Limits of Advance Directives in Maintaining Autonomy in Patients with Advanced Dementia

Limits of advance directives in decision-making around food and nutrition in patients with dementia

Advance directives are critically important for capable individuals who wish to avoid the burdens of life-prolonging interventions in the advanced stages of dementia. However, this paper will argue that advance directives should have less application to questions about feeding patients during the clinical course of dementia than often has been presumed. The argument will be framed within the debate between Ronald Dworkin and Rebecca Dresser regarding the moral authority of precedent autonomy to determine an individual's future end-of-life care plan. We will use a brief analysis of the positions taken in two important papers that come out of the Dworkin/Dresser debate and a hypothetical patient, John, who will be followed from diagnosis of dementia to death, to show how advance directives should apply to key points in the progression of his disease, particularly in relation to food and nutrition.

No playing around with robots? Ambivalent attitudes toward the use of Paro in elder care

This paper explores the ways in which health care professionals, family carers, and older persons expressed attitudes and opinions on using Paro, a social robot designed to stimulate patients with dementia. Thereafter, we critically evaluate existing prejudicial views toward Paro users to provide recommendations for its future use. Using an exploratory qualitative interview method, we recruited a total of 67 participants in Switzerland. They included 23 care professionals, 17 family carers, and 27 older persons. Data obtained were analyzed thematically. Study findings present general agreement that Paro is an appealing and beneficial social robot, but it is not a tool that everyone feels comfortable with. Because it is perceived as "child play," it would be demeaning for competent adults to play with such things. Consequently, Paro is appropriate only for persons with dementia. These findings brought forth ethical concerns about deception, infantilization, and respecting older persons' dignity. The idea of who is an appropriate Paro user led to our discussions on predicting future Paro users. The meaning of using social robotics in nursing homes can be conditioned by a rigid interpretation of adulthood and playful behavior. To protect future selves when one is living with dementia from prejudices, it may be useful for older persons and their loved ones to plan their future care situations to ensure that they are treated in accordance with their delineated decisions.

Medical aid in dying to avoid late-stage dementia

Many patients with dementia want the option of using medical aid in dying (MAID) to end their lives before losing decision-making capacity and other abilities that impact their desired quality of life. But, for over two decades, it has been widely understood that these patients cannot (solely because of their dementia diagnosis) satisfy three statutory eligibility requirements in all U.S. MAID laws: (1) decisional capacity, (2) the ability to self-administer the life-ending medications, and (3) a terminal condition with 6 months or less to live. Now, because of recent statutory amendments together with the use of voluntarily stopping eating and drinking (VSED) to quickly advance to a terminal condition, this dementia exclusion from MAID might no longer apply. If combining VSED and MAID is now a possibility for patients with dementia, then clinicians need more guidance on whether and when to support patients seeking to take this path. In this article, we begin to provide this guidance. First, we describe the recent case of an Oregon patient with early-stage Alzheimer's dementia who successfully used VSED to qualify for and use MAID. Second, we discuss prior barriers to using VSED as a bridge to MAID for people with dementia. Third, we describe recent legal changes that might make this path now possible.

Dementia Care at the End of Life: A Clinically Focused Review

With the geriatric population in the United States growing rapidly, the prevalence of dementia is expected to rise concomitantly. As dementia is an invariably progressive and terminal illness, planning for and managing end of life care in dementia is an important part of the overall process of dementia care. Unfortunately, this is often neglected outside of formal palliative and hospice medicine training programs and geriatric psychiatrists are left without preparation on how to manage, as well as counsel patients and families on, this important phase of dementia care. This review aims to explore the potential contributors to this historic disparity in geriatric education and care delivery, as well as its impact, while also attempting to shift the field's focus toward a palliative approach to dementia care. To begin to accomplish this, this review explores the natural illness history/disease trajectory of the various dementing illnesses, as well as the topic of prognostication as it pertains to the end of life for patients with dementia and how this information can be used in advanced care planning and symptom management.

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.

Change in Advance Care Plans of Nursing Home Residents With Dementia and Pneumonia: Secondary Analysis of Randomized Controlled Trial Data

OBJECTIVES

To explore changes in advance care plans of nursing home residents with dementia following pneumonia, and factors associated with changes. Second, to explore factors associated with the person perceived by older adult care physicians as most influential in advance treatment decision making.

DESIGN

Secondary analysis of physician-reported PneuMonitor trial data.

SETTING AND PARTICIPANTS

The PneuMonitor trial took place between January 2012 and May 2015 in 32 nursing homes across the Netherlands; it involved 429 residents with dementia who developed pneumonia.

METHODS

We compared advance care plans before and after the first pneumonia episode. Generalized logistic linear mixed models were used to explore associations of advance care plan changes with the person most influential in decision making, with demographics and indicators of disease progression. Exploratory analyses assessed associations with the person most influential in decision making.

RESULTS

For >90% of the residents, advance care plans had been established before the pneumonia. After pneumonia, treatment goals were revised in 15.9% of residents; 72% of all changes entailed refinements of goals. Significant associations with treatment goal changes were not found. Treatment plans changed in 20.0% of residents. Changes in treatment decisions were more likely for residents who were more severely ill (odds ratio 1.5, 95% CI 1.2-1.9) and those estimated to live <3 months (odds ratio 3.3, 95% CI 1.9-5.8). Physicians reported that a family member was often (47.4%) most influential in decision making. Who is most influential was associated with the resident's dementia severity.

CONCLUSIONS AND IMPLICATIONS

Overall, changes in advance care plans after pneumonia diagnosis were small, suggesting stability of most preferences or limited dynamics in the advance care planning process. Advance care planning involving family is common for nursing home residents with dementia, but advance care planning with persons with dementia themselves is rare and requires more attention.

Understanding Factors That Predict Advance Directive Completion

Background

Advance care planning was designed for the purpose of ensuring that patients receive care at end of life (EOL) that is congruent with their wishes, goals, and values. Despite the evidence of the negative impact of not having advance directives (ADs), only one-third of adults in the United States have written ADs. Determining the patient's goals of care in the setting of metastatic cancer is vital to the delivery of high-quality healthcare. Although much is known about barriers to AD completion (e.g., the uncertainty of the disease process and trajectory, readiness of patient and family to have these discussions, and patient-provider communication barriers), little is known about the role of both patient and caregiver factors influencing AD completion.

Objective

This study aimed to understand the relationship between patient and family caregiver demographic characteristics, and processes, and their influence on AD completion.

Design

This study was a cross-sectional descriptive correlational design and employed secondary data analysis. The sample was composed of 235 patients with metastatic cancer and their caregivers.

Results

A logistic regression analysis was performed to analyze the relationship between predictor variables and the criterion variable of AD completion. Out of the 12 predictor variables, only 2 variables (patient age and race) predicted AD completion. Of those two predictor variables, patient age made a greater and unique contribution to explaining AD completion, compared with patient race.

Conclusion

There is a need for further research on cancer patients with historical low AD completion.
