Palliative and end-of-life care for people living with dementia in rural areas: A scoping review

Background and objectives

People living with dementia deserve to experience the benefits of receiving palliative care and end-of-life services and supports, yet they often do not receive this care compared to those with other terminal diseases. People living with dementia in rural areas often face additional challenges to accessing such care. The purpose of this scoping review was to systematically review and synthesize the literature on palliative and end-of-life care for people with dementia living in rural areas, and to identify and describe key findings and gaps in the literature.

Methods

A collaborative research team approach was used in an iterative process across all stages of this review. Systematic, comprehensive searches were conducted across ten databases and eight targeted websites for relevant peer-reviewed, original research and other less formal literature, published in English, which yielded a total of 4476 results. After duplicate removal, screening, and review, 24 items were included for synthesis.

Results

All items were described and illustrated by frequency distribution, findings were grouped thematically, and five key themes emerged, including: 1) Knowledge about dementia, 2) Availability, accessibility, and utilization of palliative and end-of-life care services and supports, 3) Decision-making about care, the value of a person-centered approach and collaborative support, 4) Perspectives on artificial nutrition, hydration, and comfort care, and 5) Quality of life and death. The main gap identified was literature pertaining to rural populations, especially from locations other than the United States. The influence of rurality on relevant findings was mixed across rural-urban comparison studies, as was the effect of sex and gender across the literature.

Conclusions

Several areas were highlighted including the importance of increasing knowledge about dementia, having early conversations about advanced care and treatment options, providing a person-centered approach, and the potential for using technology to address rural access issues. These findings can be used to inform future research and policy and the development of services, supports, and strategies for rural people living with dementia. Further research is recommended.

The Efficacy and Safety of Tube Feeding in Advanced Dementia Patients: A Systemic Review and Meta-Analysis Study

OBJECTIVES

The current study aimed to conduct a systematic review and meta-analysis to explore the efficacy and safety of tube feeding in patients with advanced dementia.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

PubMed, Medline, Embase, and Cochrane Library were searched from inception until March 7, 2020, to obtain relevant studies.

INTERVENTION

Feeding with nasogastric tube or percutaneous endoscopic gastrostomy (PEG).

MEASURES

We evaluated the associations of tube feeding and the risk of mortality, period of survival days, tube-related complications, and nutritional status. Data from original studies were synthesized by using a random-effects model. Each selected article was assessed for bias using the Newcastle-Ottawa Scale. A narrative synthesis and pooled analyses are reported.

RESULTS

Twelve trials were eligible, involving 1805 patients with tube feeding (mean age: 82.8 years; 71.3% female) and 3861 without tube feeding (mean age: 82.7; 68.7% female). For mortality rate, patients with advanced dementia with tube feeding are associated with significantly higher mortality rate [k = 8; odds ratio (OR) 1.79; 95% confidence interval (CI) 1.04-3.07; P = .03]. Initially, no association was found for the risk of pneumonia and pressure sore between groups. However, sensitivity analysis showed patients with advanced dementia with PEG tube feeding have significantly higher risk of pneumonia (OR 3.56; 95% CI 2.32-5.44; P < .001) and pressure sore (OR 2.25; 95% CI 1.92-2.63; P < .001). Finally, no association was found for the survival period and nutritional status between groups.

CONCLUSIONS AND IMPLICATIONS

This meta-analysis indicates that tube feeding is associated with increased mortality rate and possible tube-related complications, but not improves with prolonging survival days and nutritional status. Shared decision-making routinely before insertion of a tube between caregivers and physicians is recommended.

International Survey of Physicians' Perspectives on Percutaneous Endoscopic Gastrostomy Tube Feeding in Patients with Dementia and Review of Literature

Percutaneous endoscopic gastrostomy (PEG) tube often remains to be used as a primary modality for feeding in patients with advanced dementia, perhaps due to misconceptions regarding the outcomes. Physicians' perceptions regarding the PEG tubes could be a significant contributing factor globally. A multidisciplinary approach involving the ethics committee can help address the issue. Our survey is focused on gauging physicians' perceptions regarding PEG tube utilization and its global impact on outcomes in dementia.

A Matter of Taste? Quality of Life in Day-to-Day Living with ALS and a Feeding Tube

Although people often refer to quality of life and there is a respectable research tradition to establish it, the meaning of the term is unclear. In this article we qualitatively study an intervention of which the quantitative effects are documented as indecisive. We do this in order to learn more about what the meaning of the term quality of life means when it is studied in daily life. With the help of these findings we reflect on the intricacies of objectifying and measuring quality of life using quantitative research designs. Our case is the feeding tube for patients suffering from ALS, a severe motor neuron disease that rapidly and progressively incapacitates patients. We studied how these patients, who lived in the Netherlands, anticipated and lived with a feeding tube in the course of their physical deterioration. Our analysis shows that the quality of life related to the feeding tube has to be understood as a process rather than as an outcome. The feeding tube becomes a different thing as patients move through the various phases of their illness, due to changes in their condition, living circumstances, and concerns and values. There are very different appreciations of the way the feeding tube changes the body's appearance and feel. Some patients refuse it because they feel it disfigures their body, whereas others are indifferent to its appearance. Our conclusion is that these differences are difficult to grasp with a quantitative study designs because 'matters of taste' and values are not distributed in a population in the same ways as physiological responses to medication. Effect studies assume physiological responses to be more or less the same for everyone, with only gradual differences. Our analysis of quality in daily life, however, shows that what a treatment comes to be and how it is valued shows shows generalities for subgroups rather than populations.

How are treatment decisions made about artificial nutrition for individuals at risk of lacking capacity? A systematic literature review

BACKGROUND

Worldwide, the number of individuals lacking the mental capacity to participate in decisions about their own healthcare is increasing. Due to the ageing global population and advancing medical treatments, there are now many more people living longer with neurological disorders, such as dementia, acquired brain injuries, and intellectual disabilities. Many of these individuals have feeding difficulties and may require artificial nutrition. However, little is known about the decision-making process; the evidence base is uncertain and often ethically complex. Using the exemplar of artificial nutrition, the objective of this review is to examine how treatment decisions are made when patients are at risk of lacking capacity.

METHODS AND FINDINGS

We undertook a systematic review according to PRISMA guidelines to determine who was involved in decisions, and what factors were considered. We searched PubMed, AMED, CINAHL, EMBASE, PsychINFO, and OpenSigle for quantitative and qualitative studies (1990-2011). Citation, reference, hand searches and expert consultation were also undertaken. Data extraction and quality assessment were undertaken independently and in duplicate. We utilised Thomas and Harden's 'Thematic Synthesis' for analysis. Sixty-six studies met inclusion criteria, comprising data from 40 countries and 34,649 patients, carers and clinicians. Six themes emerged: clinical indications were similar across countries but were insufficient alone for determining outcomes; quality of life was the main decision-making factor but its meaning varied; prolonging life was the second most cited factor; patient's wishes were influential but not determinative; families had some influence but were infrequently involved in final recommendations; clinicians often felt conflicted about their roles.

CONCLUSIONS

When individuals lack mental capacity, decisions must be made on their behalf. Dynamic interactive factors, such as protecting right to life, not unnecessarily prolonging suffering, and individual preferences, need to be addressed and balanced. These findings provide an outline to aid clinical practice and develop decision-making guidelines.

Undernutrition in older adults

Undernutrition in older persons usually presents as weight loss and is predominantly due to protein energy wasting. The presentation of undernutrition is often subtle in older persons and there is a need to utilize screening tools and increasing physician awareness. There are multiple treatable causes of undernutrition in older persons. The major causes are anorexia, cachexia, sarcopenia, dehydration, malabsorption and hypermetabolism. This article also provides an overview of the use of nutritional supplements and an approach to managing protein energy wasting.
