Continuous Deep Sedation Until Death in Nursing Home Residents with Dementia: A Case Series

Continuous Palliative Sedation Until Death: The Development of a Practice Protocol for Nursing Homes

OBJECTIVES

Challenges inherent in the practice of continuous palliative sedation until death appear to be particularly pervasive in nursing homes. We aimed to develop a protocol to improve the quality of the practice in Belgian nursing homes.

METHODS

The development of the protocol was based on the Medical Research Council Framework and made use of the findings of a systematic review of existing improvement initiatives and focus groups with 71 health care professionals [palliative care physicians, general practitioners (GPs), and nursing home staff] identifying perceived barriers to the use of continuous palliative sedation until death in nursing homes. The protocol was then reviewed and refined by another 70 health care professionals (palliative care physicians, geriatricians, GPs, and nursing home staff) through 10 expert panels.

RESULTS

The final protocol was signed off by expert panels after 2 consultation rounds in which the remaining issues were ironed out. The protocol encompassed 7 sequential steps and is primarily focused on clarification of the medical and social situation, communication with all care providers involved and with the resident and/or relatives, the organization of care, the actual performance of continuous sedation, and the supporting of relatives and care providers during and after the procedure. Although consistent with existing guidelines, our protocol describes more comprehensively recommendations about coordination and collaboration practices in nursing homes as well as specific matters such as how to communicate with fellow residents and give them the opportunity to say goodbye in some way to the person who is dying.

CONCLUSIONS AND IMPLICATIONS

This study succeeded in developing a practice protocol for continuous palliative sedation until death adapted to the specific context of nursing homes. Before implementing it, future research should focus on developing profound implementation strategies and on thoroughly evaluating its effectiveness.

Barriers in the Decision Making About and Performance of Continuous Sedation Until Death in Nursing Homes

BACKGROUND AND OBJECTIVES

While decision making about and performance of continuous sedation involve many challenges, they appear to be particularly pervasive in nursing homes. This study aims to identify barriers to the decision making and performance of continuous sedation until death in Flemish nursing homes as experienced by the health care professionals involved.

RESEARCH DESIGN AND METHODS

Ten focus groups were held with 71 health care professionals including 16 palliative care physicians, 42 general practitioners, and 13 nursing home staff. Discussions were transcribed verbatim and analyzed using a constant comparative approach.

RESULTS

Perceived barriers concerned factors prior to and during sedation and were classified according to three types: (a) personal barriers related to knowledge and skills including the lack of clarity on what continuous sedation should be used for (linguistic ambiguity) and when and how it should be used (practical ambiguity); (b) relational barriers concerning communication and collaboration both between health care professionals and with family; (c) organizational barriers related to the organization of care in nursing homes where, for example, there is no on-site physician, or where the recommended medication is not always available.

DISCUSSION AND IMPLICATIONS

The findings suggest there are considerable challenges for sound decision making about and performance of continuous sedation until death in nursing homes. There is a need for multicomponent initiatives that provide guidance in the context of the complexity of a resident's medical situation, the family, and the specific organization of care, which would have the potential to facilitate and improve the decision-making process and performance of continuous sedation in nursing homes.

Sedatives and Sedation at the End of Life in Nursing Homes: A Retrospective Multicenter Cohort Study

OBJECTIVES

There is scarce information about sedation in nursing homes at the end of life. We aimed to assess (1) the use of sedatives generally and "sedatives with continuous effect," based on objective operational criteria, within the last week of life in nursing homes and (2) factors associated with this treatment.

DESIGN

Retrospective cohort study, using the nursing homes' medical records.

SETTING AND PARTICIPANTS

Residents who died in 4 German nursing homes from January 2015 to December 2017 and whose medical records were available (n = 512).

METHODS

Sedatives analyzed were those recommended by guidelines for "palliative sedation": benzodiazepines, levomepromazine, haloperidol (≥5 mg/d), and propofol. The definition of "sedatives with continuous effect" and doses judged as at least moderately sedating were consented by palliative care clinicians and pharmacists, based on the literature. Descriptive statistics and multivariate logistic regression analysis were performed (R version 3.6.1).

RESULTS

Overall, 110/512 (21%) deceased residents received a sedative at least once during the last week of life, 46/512 (9%) "sedatives with continuous effect." Oral lorazepam was used most frequently. Eleven of 512 (2%) residents received doses judged as at least moderately sedating. The term sedation was not used. Most frequent indications were agitation (58/110; 53%) and anxiety (35/110; 32%); no indication was noted for 36/110 (33%) residents. The resident's involvement in the decision for sedatives was documented in 3/110 (3%). Multivariate logistic regression analysis showed significant associations between use of sedatives and age (OR = 0.94, P < .001) as well as institution (P < .001).

CONCLUSIONS AND IMPLICATIONS

Our data indicate a lower prevalence of sedation compared to international data and considerable differences regarding prevalence between institutions. These differences, potential setting-specific challenges, and need for support measures for consistent best practice of sedation in nursing homes should be further explored.

Changing Practices in the Use of Continuous Sedation at the End of Life: A Systematic Review of the Literature

CONTEXT

The use of continuous sedation until death (CSD) has been highly debated for many years. It is unknown how the use of CSD evolves over time. Reports suggest that there is an international increase in the use of CSD for terminally ill patients.

OBJECTIVE

To gain insight in developments in the use of CSD in various countries and subpopulations.

METHODS

We performed a search of the literature published between January 2000 and April 2020, in PubMed, Embase, CINAHL, PsycInfo, and the Cochrane Library by using the Preferred reporting items for systematic review and meta-analysis protocols guidelines. The search contained the following terms: continuous sedation, terminal sedation, palliative sedation, deep sedation, end-of-life sedation, sedation practice, and sedation until death.

RESULTS

We found 23 articles on 16 nationwide studies and 38 articles on 37 subpopulation studies. In nationwide studies on frequencies of CSD in deceased persons varied from 3% in Denmark in 2001 to 18% in The Netherlands in 2015. Nationwide studies indicate an increase in the use of CSD. Frequencies of CSD in the different subpopulations varied too widely to observe time trends. Over the years, more studies reported on the use of CSD for nonphysical symptoms including fear, anxiety, and psycho-existential distress. In some studies, there was an increase in requests for sedation of patients from their families.

CONCLUSIONS

The frequency of CSD seems to increase over time, possibly partly because of an extension of indications for sedation, from mainly physical symptoms to also nonphysical symptoms.

Physician and Surrogate Agreement with Assisted Dying and Continuous Deep Sedation in Advanced Dementia in Switzerland

BACKGROUND

Assisted dying and continuous deep sedation (CDS) are controversial practices. Little is known about the perceptions of physicians and surrogates about these practices for patients with advanced dementia.

OBJECTIVES

To describe and compare physician and surrogate agreement with the use of assisted dying and CDS in advanced dementia.

DESIGN, SETTING, SUBJECTS

Physicians (n = 64) and surrogates (n = 168) of persons with advanced dementia were recruited as part of a randomized controlled trial in Switzerland that tested decision support tools in this population.

METHODS

At baseline, the participants were asked about their agreement with assisted dying and CDS in advanced dementia using the following response options: "completely agree," "somewhat agree," "somewhat disagree," "completely disagree," and "do not know." Multivariable logistic regressions compared the likelihood that surrogates versus physicians would completely or somewhat agree (vs. completely or somewhat disagree) with these practices.

RESULTS

The physicians and surrogates, respectively, had a mean age (SD) of 50.6 years (9.9) and 57.4 years (14.6); 46.9% (n = 30/64) and 68.9% (n = 115/167) were women. A total of 20.3% (n = 13/64) of the physicians and 47.0% (n = 79/168) of the surrogates agreed with assisted dying in advanced dementia. Surrogates were significantly more likely to agree with this practice than physicians (adjusted odds ratio, 3.87; 95% CI: 1.94, 7.69). With regard to CDS, 51.6% (n = 33/64) of the physicians and 41.9% (n = 70/169) of the surrogates agreed with this practice, which did not differ significantly between the groups.

CONCLUSIONS

The surrogates were more agreeable to considering assisted dying in the setting of advanced dementia than the physicians, and about half of the participants in both groups reported CDS to be an appropriate option for this population.

Systematic review of general practice end-of-life symptom control

Background

End of life care (EoLC) is a fundamental role of general practice, which will become more important as the population ages. It is essential that general practice’s role and performance of at the end of life is understood in order to maximise the skills of the entire workforce.

Objective

To provide a comprehensive description of the role and performance of general practitioners (GPs) and general practice nurses (GPNs) in EoLC symptom control.

Method

Systematic literature review of papers from 2000 to 2017 were sought from Medline, PsycINFO, Embase, Joanna Briggs Institute and Cochrane databases.

Results

From 6209 journal articles, 46 papers reported GP performance in symptom management. There was no reference to the performance of GPNs in any paper identified. Most GPs expressed confidence in identifying EoLC symptoms. However, they reported lack of confidence in providing EoLC at the beginning of their careers, and improvements with time in practice. They perceived emotional support as being the most important aspect of EoLC that they provide, but there were barriers to its provision. GPs felt most comfortable treating pain, and least confident with dyspnoea and depression. Observed pain management was sometimes not optimal. More formal training, particularly in the use of opioids was considered important to improve management of both pain and dyspnoea.

Conclusions

It is essential that GPs receive regular education and training, and exposure to EoLC from an early stage in their careers to ensure skill and confidence. Research into the role of GPNs in symptom control needs to occur.

Nurses' perspectives on whether medical aid in dying should be accessible to incompetent patients with dementia: findings from a survey conducted in Quebec, Canada

We conducted a survey in a random sample of 514 Quebec nurses caring for the elderly to assess their attitudes towards extending medical aid in dying to incompetent patients and to explore associated factors. Attitudes were measured using clinical vignettes featuring a hypothetical patient with Alzheimer disease. Vignettes varied according to the stage of the disease (advanced or terminal) and the presence or absence of a written request. Of the 291 respondents, 83.5% agreed with the current legislation that allows physicians to administer aid in dying to competent patients who are at the end of life and suffer unbearably. A similar proportion (83%, p = 0.871) were in favor of extending medical aid in dying to incompetent patients who are at the terminal stage of Alzheimer disease, show signs of distress, and have made a written request before losing capacity.

Dying well with reduced agency: a scoping review and thematic synthesis of the decision-making process in dementia, traumatic brain injury and frailty

Background

In most Anglophone nations, policy and law increasingly foster an autonomy-based model, raising issues for large numbers of people who fail to fit the paradigm, and indicating problems in translating practical and theoretical understandings of ‘good death’ to policy. Three exemplar populations are frail older people, people with dementia and people with severe traumatic brain injury. We hypothesise that these groups face some over-lapping challenges in securing good end-of-life care linked to their limited agency. To better understand these challenges, we conducted a scoping review and thematic synthesis.

Methods

To capture a range of literature, we followed established scoping review methods. We then used thematic synthesis to describe the broad themes emerging from this literature.

Results

Initial searches generated 22,375 references, and screening yielded 49, highly heterogeneous, studies that met inclusion criteria, encompassing 12 countries and a variety of settings. The thematic synthesis identified three themes: the first concerned the processes of end-of-life decision-making, highlighting the ambiguity of the dominant shared decision-making process, wherein decisions are determined by families or doctors, sometimes explicitly marginalising the antecedent decisions of patients. Despite this marginalisation, however, the patient does play a role both as a social presence and as an active agent, by whose actions the decisions of those with authority are influenced. The second theme examined the tension between predominant notions of a good death as ‘natural’ and the drive to medicalise death through the lens of the experiences and actions of those faced with the actuality of death. The final theme considered the concept of antecedent end-of-life decision-making (in all its forms), its influence on policy and decision-making, and some caveats that arise from the studies.

Conclusions

Together these three themes indicate a number of directions for future research, which are likely to be applicable to other conditions that result in reduced agency. Above all, this review emphasises the need for new concepts and fresh approaches to end of life decision-making that address the needs of the growing population of frail older people, people with dementia and those with severe traumatic brain injury.

Prospective Observations of Discomfort, Pain, and Dyspnea in Nursing Home Residents With Dementia and Pneumonia

OBJECTIVES

To describe observations of suffering in patients with dementia from the diagnosis of pneumonia until cure or death.

DESIGN

Prospective observational study between January 2012 and May 2014.

SETTING

Dutch nursing homes (32).

PARTICIPANTS

Nursing home patients with dementia and pneumonia (n = 193).

MEASUREMENTS

Independent observers performed observations of patients with dementia scheduled 13 times within the 15 days following diagnosis of pneumonia; twice daily in the first 2 days- to observe discomfort (Discomfort Scale-Dementia of Alzheimer Type; range 0-27), comfort (End Of Life in Dementia-Comfort Assessment in Dying; range 14-42), pain (Pain Assessment in Advanced Dementia; range 0-10), and dyspnea (Respiratory Distress Observation Scale; range 0-16).

RESULTS

Observational data were obtained for 208 cases of pneumonia in 193 patients. In 71.2% of cases, patients received 1 or more treatments to relieve symptoms such as antipyretics, opioids, or oxygen; 89.4% received antibiotics. Discomfort was highest 1 day after diagnosis [mean Discomfort Scale-Dementia of Alzheimer Type score 8.1 (standard deviation, SD 5.8)], then declined, and stabilized around day 10 [mean 4.5 (SD 4.1)], or increased in the days preceding death. Observed pain and dyspnea followed a comparable pattern. Discomfort patterns did not differ much between cases treated with and without antibiotics.

CONCLUSIONS

Pneumonia in patients with dementia involved elevated levels of suffering during 10 days following diagnosis and in the days preceding death. Overall observed discomfort was low compared with prior Dutch studies, and the number of treatments to relieve symptoms was higher. Future studies should examine whether symptoms of pneumonia can be relieved even more, and what treatments are the most effective.

Awareness of dementia by family carers of nursing home residents dying with dementia: a post-death study

BACKGROUND

High-quality palliative care for people with dementia should be patient-centered, family-focused, and include well-informed and shared decision-making, as affirmed in a recent white paper on dementia from the European Association for Palliative Care.

AIM

To describe how often family carers of nursing home residents who died with dementia are aware that their relative has dementia, and study resident, family carer, and care characteristics associated with awareness.

DESIGN

Post-death study using random cluster sampling.

SETTING/PARTICIPANTS

Structured questionnaires were completed by family carers, nursing staff, and general practitioners of deceased nursing home residents with dementia in Flanders, Belgium (2010).

RESULTS

Of 190 residents who died with dementia, 53.2% of family carers responded. In 28% of cases, family carers indicated they were unaware their relative had dementia. Awareness by family carers was related to more advanced stages of dementia 1 month before death (odds ratio = 5.4), with 48% of family carers being unaware when dementia was mild and 20% unaware when dementia was advanced. The longer the onset of dementia after admission to a nursing home, the less likely family carers were aware (odds ratio = 0.94).

CONCLUSION

Family carers are often unaware that their relative has dementia, that is, in one-fourth of cases of dementia and one-fifth of advanced dementia, posing considerable challenges for optimal care provision and end-of-life decision-making. Considering that family carers of residents who develop dementia later after admission to a nursing home are less likely to be aware, there is room for improving communication strategies toward family carers of nursing home residents.

Towards a standardised approach for evaluating guidelines and guidance documents on palliative sedation: study protocol

Background

Sedation in palliative care has received growing attention in recent years; and so have guidelines, position statements, and related literature that provide recommendations for its practice. Yet little is known collectively about the content, scope and methodological quality of these materials.

According to research, there are large variations in palliative sedation practice, depending on the definition and methodology used. However, a standardised approach to comparing and contrasting related documents, across countries, associations and governmental bodies is lacking. This paper reports on a protocol designed to enable thorough and systematic comparison of guidelines and guidance documents on palliative sedation.

Methods and design

A multidisciplinary and international group of palliative care researchers, identified themes and clinical issues on palliative sedation based on expert consultations and evidence drawn from the EAPC (European Association of Palliative Care) framework for palliative sedation and AGREE II (Appraisal Guideline Research and Evaluation) instrument for guideline assessment. The most relevant themes were selected and built into a comprehensive checklist. This was tested on people working closely with practitioners and patients, for user-friendliness and comprehensibility, and modified where necessary. Next, a systematic search was conducted for guidelines in English, Dutch, Flemish, or Italian. The search was performed in multiple databases (PubMed, CancerLit, CNAHL, Cochrane Library, NHS Evidence and Google Scholar), and via other Internet resources. Hereafter, the final version of the checklist will be used to extract data from selected literature, and the same will be compiled, entered into SPSS, cleaned and analysed systematically for publication.

Discussion

We have together developed a comprehensive checklist in a scientifically rigorous manner to allow standardised and systematic comparison. The protocol is applicable to all guidelines on palliative sedation, and the approach will contribute to rigorous and systematic comparison of international guidelines on any challenging topic such as this. Results from the study will provide valuable insights into common core elements and differences between the selected guidelines, and the extent to which recommendations are derived from, or match those in the EAPC framework. The outcomes of the study will be disseminated via peer-reviewed journals and directly to appropriate audiences.

Making sense of continuous sedation in end-of-life care for cancer patients: an interview study with bereaved relatives in three European countries

PURPOSE

The purpose of the study was to explore relatives' descriptions and experiences of continuous sedation in end-of-life care for cancer patients and to identify and explain differences between respondents from the Netherlands, Belgium, and the UK.

METHODS

In-depth interviews were held between January 2011 and May 2012 with 38 relatives of 32 cancer patients who received continuous sedation until death in hospitals, the community, and hospices/palliative care units.

RESULTS

Relatives' descriptions of the practice referred to the outcome, to practical aspects, and to the goals of sedation. While most relatives believed sedation had contributed to a 'good death' for the patient, yet many expressed concerns. These related to anxieties about the patient's wellbeing, their own wellbeing, and questions about whether continuous sedation had shortened the patient's life (mostly UK), or whether an alternative approach would have been better. Such concerns seemed to have been prompted by relatives witnessing unexpected events such as the patient coming to awareness during sedation. In the Netherlands and in Belgium, several relatives reported that the start of the sedation allowed for a planned moment of 'saying goodbye'. In contrast, UK relatives discerned neither an explicit point at which sedation was started nor a specific moment of farewell.

CONCLUSIONS

Relatives believed that sedation contributed to the patient having a good death. Nevertheless, they also expressed concerns that may have been provoked by unexpected events for which they were unprepared. There seems to exist differences in the process of saying goodbye between the NL/BE and the UK.
