Relieving existential suffering through palliative sedation: discussion of an uneasy practice

Continuous palliative sedation until death: a qualitative study of palliative care clinicians' experiences

BACKGROUND

The practice of continuous palliative sedation until death is the subject of much medical and ethical debate, which is reflected in the inconsistency that persists in the literature regarding the definition and indications of palliative sedation.

AIM

This study aims to gain a better understanding of palliative care clinicians' experiences with continuous palliative sedation.

DESIGN

We conducted a qualitative study based on focus group discussions.

SETTING/PARTICIPANTS

We conducted six focus groups with a total of 28 palliative care clinicians (i.e., 15 nurses, 12 physicians, and 1 end-of-life doula) from diverse care settings across Canada, where assisted dying has recently been legalized.

RESULTS

An interpretative phenomenological analysis was used to consolidate the data into six key themes: responding to suffering; grappling with uncertainty; adapting care to ensure ongoing quality; grounding clinical practice in ethics; combining medical expertise, relational tact, and reflexivity; and offering an alternative to assisted death.

CONCLUSIONS

Interaction with the patient's family, uncertainty about the patient's prognosis, the concurrent practice of assisted dying, and the treatment of existential suffering influence the quality of sedation and indicate a lack of clear palliative care guidelines. Nevertheless, clinicians exhibit a reflective and adaptive capacity that can facilitate good practice.

Palliative sedation determinants: systematic review and meta-analysis in palliative medicine

BACKGROUND

The utilisation of palliative sedation is often favoured by patients approaching end of life due to the presence of multiple difficult-to-manage symptoms during the terminal stage. This study aimed to identify the determinants of the use of palliative sedation.

METHODS

To identify pertinent observational studies, a comprehensive search was performed in PubMed, Embase, Cochrane Library, and PsycINFO databases from their inception until March 2022. The methodological quality of the chosen prospective and retrospective cohort studies was assessed using the Newcastle Ottawa Scale, while the Agency for Healthcare Research and Quality was used to evaluate the methodological quality of the selected cross-sectional studies. For each potential determinant of interest, the collected data were synthesised and analysed, and in cases where data could not be combined, a narrative synthesis approach was adopted.

RESULTS

A total of 21 studies were analysed in this research, consisting of 4 prospective cohort studies, 7 retrospective cohort studies, and 10 cross-sectional studies. The findings indicated that several determinants were significantly associated with palliative sedation. These determinants included younger age, male gender, presence of tumours, dyspnoea, pain, delirium, making advanced medical end-of-life decisions, and dying in a hospital setting.

CONCLUSIONS

The findings of our review could help physicians identify patients who may need palliative sedation in advance and implement targeted interventions to reverse refractory symptoms, develop personalized palliative sedation programs, and ultimately improve the quality of palliative care services.

Finding the Hidden Professional Culture of Mental Health Nursing-Spiritual Care for Individuals with a Co-morbid Life-Limiting Illness

People with severe mental illness are dying up to thirty years earlier than the general population. The limited literature on their experience of dying indicates that they often suffer from inequities in their access to healthcare services, and further, what care they do receive is frequently poor. Living with both a mental illness and facing death can engender spiritual concerns and dying at a younger age is a risk factor for spiritual despair. Hence, addressing spiritual concerns can be an important dimension of mental health nursing care. The aim of this ethnographic study of 11 senior and experienced mental health nurses was to determine if the culture of the mental health service impacted their spiritual care for those patients who were facing death. The data highlighted that the nurses felt comfortable in providing spiritual care when the person was suffering from psychosis. Yet, the results also revealed that nurses felt disempowered by the dominance of the biomedical culture, in which they felt unable to articulate their care. However, it was identified that their spiritual care was inherent within the professional values, knowledge, and skills of mental health nursing and framed through their therapeutic relationships. Therefore, strategies need to be used by the organization to assist nurses to reclaim their power and assist the mental health service to further develop and engage in spiritual care practices.

Survival Outcomes in Palliative Sedation Based on Referring Versus On-Call Physician Prescription

This study sought to determine the survival duration of patients who underwent palliative sedation, comparing those who received prescriptions from referring physicians versus on-call physicians. It included all patients over 18 years old who died in the Palliative Care, Internal Medicine, and Oncology units at the Hospital Universitario of Jerez de la Frontera between 1 January 2019, and 31 December 2019. Various factors were analyzed, including age, gender, oncological or non-oncological disease, type of primary tumor and refractory symptoms. Statistical analysis was employed to compare survival times between patients who received palliative sedation from referring physicians and those prescribed by on-call physicians, while accounting for other potential confounding variables. This study revealed that the median survival time after the initiation of palliative sedation was 25 h, with an interquartile range of 8 to 48 h. Notably, if the sedation was prescribed by referring physicians, the median survival time was 30 h, while it decreased to 17 h when prescribed by on-call physicians (RR 0.357; 95% CI 0.146-0.873; p = 0.024). Furthermore, dyspnea as a refractory symptom was associated with a shorter survival time (RR 0.307; 95% CI 0.095-0.985; p = 0.047). The findings suggest that the on-call physician often administered palliative sedation to rapidly deteriorating patients, particularly those experiencing dyspnea, which likely contributed to the shorter survival time following sedation initiation. This study underscores the importance of careful patient selection and prompt initiation of palliative sedation to alleviate suffering.

Cross-cultural comparison of continuous deep sedation for advanced cancer patients in East Asian countries: prospective cohort study

OBJECTIVE

Cultural, social, and legal factors have been known to affect physicians' practice of continuous deep sedation. There have been few quantitative studies to compare continuous deep sedation practice in Asian countries. We aimed to describe and compare clinical characteristics of continuous deep sedation in Japan, Korea and Taiwan.

METHODS

Patients with advanced cancer admitted to participating palliative care units were enrolled from January 2017 to September 2018. We evaluated and compared (i) the prevalence of continuous deep sedation, (ii) the characteristics of sedated and non-sedated groups in each country, and (iii) continuous deep sedation administration patterns among the three countries.

RESULTS

A total of 2158 participants were included in our analysis, and 264 received continuous deep sedation. The continuous deep sedation prevalence was 10, 16 and 22% in Japan, Korea and Taiwan, respectively. Delirium was the most frequent target symptom in all countries, along with dyspnoea (in Japan) and psychological symptoms (in Korea). Midazolam was most frequently used in Japan and Taiwan, but not in Korea (P < 0.001). Among the patients receiving continuous deep sedation, the hydration amount on the final day was significantly different, with median volumes of 200, 500 and 0 mL in Japan, Korea and Taiwan, respectively (P < 0.001). In Korea, 33% of the continuous deep sedation administration caused a high degree of physicians' discomfort, but 3% in Japan and 5% in Taiwan (P < 0.001).

CONCLUSIONS

Clinical practices of continuous deep sedation and physicians' discomfort related to continuous deep sedation initiation highly varied across countries. We need to develop optimal decision-making models of continuous deep sedation and hydration during continuous deep sedation in each country.

Possible age-related differences in healthcare professionals' perspectives on younger and older patients' autonomy and decision-making in the context of sedation in specialised palliative care: exploratory secondary qualitative content and linguistic conversation analysis of interviews with healthcare professionals

Background

Chronic illnesses and multi-morbidity can threaten competence and independence, particularly in old age. Autonomy becomes increasingly important in the context of sedation, as in this case medication leads to (further) changes of consciousness. The study aimed to identify possible age-related differences in the perspectives of healthcare professionals on patients’ autonomy, in the context of sedation in specialised palliative care.

Method

Secondary analysis of interviews with healthcare professionals, analysed by qualitative content and linguistic conversation analysis. The interviews analysed span 51 healthcare professionals in specialised palliative care across 17 centres (adult inpatient and specialist palliative home care services) in Germany.

Results

The study shows that the perspectives of healthcare professionals on patients’ autonomy differs according to the age of the patient in the context of sedation in specialised palliative care. The different perspectives may lead to different ways of treating the patients, for example a greater space of autonomy and decision-making for younger patients.

Conclusion

In particular, measures that may restrict consciousness (e.g. sedation) and thus influence patients’ ability to fully exercise their autonomy and fully participate in decision-making require special attention by healthcare professionals with respect to possible influences on treatment, such as different perceptions by healthcare professionals based on the patient’s age or age-related stereotypes.

Trial registration

The study “SedPall” is registered in the German Clinical Trials Register (ID: DRKS00015047).

Four aspects of spiritual care: a phenomenological action research study on practicing and improving spiritual care at two Danish hospices

BACKGROUND

In Denmark and internationally, there has been an increased focus on strengthening palliative care by enhancing spiritual care. Dying patients, however, do not experience their spiritual needs being adequately met.

METHODS

Through an action research study design with four consecutive stages, namely, observation in practice, reflection-on-praxis, action-in-praxis, and evaluation of the action research process involving patients and hospice staff from two hospices in Denmark, two research questions were explored: (1) How do patients and staff perceive, feel, live, practice, and understand spiritual care at hospice? and (2) How can spiritual care be improved in hospice practice? The data material presented comprised 12 individual interviews with patients and nine focus group interviews with the staff.

RESULTS

We found four aspects of spiritual care through which patients and staff seemed to perceive, feel, live, practice, and understand spiritual care at hospice, and from where spiritual care may be improved in hospice practice. These aspects constituted four themes: (1) relational, (2) individualistic, (3) embodied, and (4) verbal aspects of spiritual care.

CONCLUSION

Staff realized immanent limitations of individual aspects of spiritual care but learned to trust that their relational abilities could improve spiritual care. Embodied aspects seemed to open for verbal aspects of spiritual care, but staff were reluctant to initiative verbal dialogue. They would bodily sense values about preserving patients' boundaries in ways that seemed to hinder verbal aspects of spiritual care. During action-in-praxis, however, staff realized that they might have to initiate spiritual conversation in order to care for patients' spiritual needs.

Increasing our understanding of nonphysical suffering within palliative care: A scoping review

Objective

Nonphysical suffering is emotional, psychological, existential, spiritual, and/or social in nature. While palliative care is a discipline dedicated to the prevention and relief of suffering — both physical and nonphysical — little is known about existing research specific to nonphysical suffering within the context of palliative care. This scoping review helps to fill this gap.

Method

Three hundred and twenty-eight unique records were identified through a systematic search of three databases (MEDLINE, CINAHL, and PsycINFO). The following keywords were used: (suffering) AND (palliative OR “end of life” OR “end-of-life” OR hospice OR dying OR terminal* ill*). Thirty studies published between 1998 and 2019 met the inclusion criteria.

Results

Losses, worries, and fears comprise patients’ primary sources of nonphysical suffering. Patients face numerous barriers in expressing their nonphysical suffering to healthcare providers. The idea that patients can choose how they perceive their circumstances, thereby minimizing their nonphysical suffering, is pervasive in the research. The nature of nonphysical suffering experienced by family caregivers and palliative care clinicians is revealed in the review. The unique and sensitive interplay between nonphysical suffering and both palliative sedation and requests for hastened death is also evident. Overall, seven themes can be identified: (i) patients’ experiences of nonphysical suffering; (ii) patient coping mechanisms; (iii) efforts to measure nonphysical suffering; (iv) palliative sedation; (v) requests for hastened death; (vi) family suffering; and (vii) clinician suffering.

Significance of results

This is the first scoping review to map palliative care's research specific to suffering that is social, emotional, spiritual, psychological, and/or existential in nature. Its findings expand our understanding of the nature of nonphysical suffering experienced by patients, families, and palliative care clinicians. The review's findings have significant implications for front-line practice and future research.

Refractory psycho-existential distress and continuous deep sedation until death in palliative care: The French perspective

OBJECTIVE

Since February 2016, French Claeys-Leonetti law has recognized patients' right to confront incurable diseases with short-term prognosis and refractory physical or psychological or existential symptoms by requesting continuous deep sedation until death (CDSUD). Determining when psychological or existential distress is refractory and unbearable remains complex and controversial.This review provides a comprehensive thought on CDSUD for advanced incurable patients with refractory psychological and/or existential distress in palliative care settings. It offers guidance on psychiatric or psychological diagnosis for explaining patients' requests for CDSUD.

METHOD

A narrative literature review (2000-2019) was conducted on the MedLine search about the use of palliative sedation in cases of refractory psychological and/or existential distress.

RESULTS

(1) Definitions of "refractory symptom," "refractory psychological distress," and "refractory existential distress" are inconsistent; (2) alternative diagnoses might obscure or be obscured by psycho-existential distress; and (3) criteria on meanings, reasons for requests, decision-making processes, and functions are evolving in practice.

SIGNIFICANCE OF RESULTS

Before implementing CDSUD, palliative healthcare professionals should seek input from psycho-oncologists in palliative care. Mental health professionals should analyze and assess the reasons for psychological and/or existential distress, consider the intentionality processes of requests, and explore alternative diagnoses, such as depressive or adjustment disorders, demoralization syndrome, desire to hasten death, and desire for euthanasia. Therapeutic responses (e.g., pharmacological and psychotherapeutic) should be implemented before deciding that psycho-existential distress is refractory.

What is spiritual care? Professional perspectives on the concept of spiritual care identified through group concept mapping

OBJECTIVES

The overall study aim was to synthesise understandings and experiences regarding the concept of spiritual care (SC). More specifically, to identify, organise and prioritise experiences with the way SC is conceived and practised by professionals in research and the clinic.

DESIGN

Group concept mapping (GCM).

SETTING

The study was conducted within a university setting in Denmark.

PARTICIPANTS

Researchers, students and clinicians working with SC on a daily basis in the clinic and/or through research participated in brainstorming (n=15), sorting (n=15), rating and validation (n=13).

RESULTS

Applying GCM, ideas were identified, organised and prioritised online. A total of 192 unique ideas of SC were identified and organised into six clusters. The results were discussed and interpreted at a validation meeting. Based on input from the validation meeting a conceptual model was developed. The model highlights three overall themes: (1) 'SC as an integral but overlooked aspect of healthcare' containing the two clusters SC as a part of healthcare and perceived significance; (2) 'delivering SC' containing the three clusters quality in attitude and action, relationship and help and support, and finally (3) 'the role of spirituality' containing a single cluster.

CONCLUSION

Because spirituality is predominantly seen as a fundamental aspect of each individual human being, particularly important during suffering, SC should be an integral aspect of healthcare, although it is challenging to handle. SC involves paying attention to patients' values and beliefs, requires adequate skills and is realised in a relationship between healthcare professional and patient founded on trust and confidence.

Palliative sedation and medical assistance in dying: Distinctly different or simply semantics?

Medical assistance in dying (MAiD) and palliative sedation (PS) are both legal options in Canada that may be considered by patients experiencing intolerable and unmanageable suffering. A contentious, lively debate has been ongoing in the literature regarding the similarities and differences between MAiD and PS. The aim of this paper is to explore the propositions that MAiD and PS are essentially similar and conversely that MAiD and PS are distinctly different. The relevance of such a debate is apparent for clinicians and patients alike. Understanding the complex and multi‐faceted nuances between PS and MAiD allows patients and caregivers to make more informed decisions pertaining to end‐of‐life care. It is hoped that this paper will also serve to foster further debate and consideration of the issues associated with PS and MAiD with a view to improve patient care and the quality of both living and dying in Canada.

Moral identity and palliative sedation: A systematic review of normative nursing literature

Background:

In the last two decades, nursing authors have published ethical analyses of palliative sedation—an end-of-life care practice that also receives significant attention in the broader medical and bioethics literature. This nursing literature is important, because it contributes to disciplinary understandings about nursing values and responsibilities in end-of-life care.

Research aim:

The purpose of this project is to review existing nursing ethics literature about palliative sedation, and to analyze how nurses’ moral identities are portrayed within this literature.

Research design:

We reviewed discussion papers, written by nurses about the ethics of palliative sedation, which were cited in MEDLINE, CINAHL, Nursing and Allied Health, or Philosopher’s Index (search date March 2018). Twenty-one papers met selection criteria. We performed a comprehensive review and analysis (using the Qualitative Analysis Guide of Leuven), of the values, responsibilities, and relationships reflected in authors’ portrayal of the nursing role.

Findings:

Two different tones are apparent in the extant nursing ethics literature. One is educational, while the other is critically reflective. Irrespective of tone, all authors agree on the alleviation of suffering as a fundamental nursing responsibility. However, they differ in their analysis of this responsibility in relation to other values in end-of-life care, including those that depend on consciousness. Finally, authors emphasize the importance of subjective and experience-based understandings of palliative sedation, which they argue as depending on nurses’ proximity to patients and families in end-of-life care.

Discussion and conclusion:

Based on our findings, we develop three recommendations for future writing by nurses about palliative sedation. These relate to the responsibility of recognizing how consciousness might matter in (some) peoples’ moral experiences of death and dying, to the importance of moral reflectiveness in nursing practice, and to the value of a relational approach in conceptualizing the nursing ethics of palliative sedation.

Dealing with ethical and existential issues at end of life through co-creation

BACKGROUND

In research on co-creation in nursing, a caring manner can be used to create opportunities for the patient to reach vital goals and thereby increase the patient's quality of life in palliative home care. This can be described as an ethical cornerstone and the goal of palliative care. Nurses must be extra sensitive to patients' and their relatives' needs with regard to ethical and existential issues and situations in home care encounters, especially at the end of life.

AIM

The aim of this study was to explore nurses' experiences of dealing with ethical and existential issues through co-creation at the end of life in palliative home care.

RESEARCH DESIGN, PARTICIPANTS, AND RESEARCH CONTEXT

The material consisted of texts from interviews with 12 nurses in a home care context. A hermeneutical approach was used, and the method was inspired by a thematic analysis.

ETHICAL CONSIDERATIONS

Informed consent was sought from the participants regarding study participation and the storage and handling of data for research purposes. Ethical permission to conduct the study was given from organizations that participated in this study.

FINDINGS

A main theme and four subthemes emerged. The main theme was "Deep co-creative relationships are needed to manage ethical and existential issues at the end of life." A model was created to display the findings and relations between ethical issues and situations and the need for a deep trustful caring relationship to solve problems in palliative home care.

DISCUSSION

Together, the themes can be considered as a tool for learning and dealing with ethical and existential issues at the end of life in home care. The themes can also be seen as a part of nurses' ethical competence within this context.

CONCLUSION

The quality of life at the end of life can be improved through co-creation, despite difficult ethical and existential issues. Future research should focus on co-creation from the patients' perspective.

The nature of suffering and its relief: a proposal for a redefinition

Recent advances in our understanding of the nature of suffering and its different dimensions have exposed certain deficits in the current definition of suffering. These shortcomings have impacted negatively on the appropriate formulation of precise treatment objectives for each dimension of suffering within the overall framework of the goals of medicine. Existential suffering offers a clear example where the lack of a universally accepted definition has led to confusion regarding what should constitute appropriate relief for this particular dimension of suffering. In this thought piece, we propose a redefinition of suffering based on three elements: first, suffering refers to a specific state of a person (the essence of suffering); second, this state is characterised by a specific psychosomatic anguish reaction (the manifestation of suffering) and third, this reaction is in response to a perceived threat to the integrity of the person (the cause of suffering). The proposed definition allows for an important and clear distinction to be made between the primary and symptomatic relief of suffering and the role of medicine in each form of relief. The terms of the proposed definition and the distinction between primary and symptomatic relief provide useful tools for further research regarding the different dimensions of suffering and its relief.

Medically Assisted Dying in Canada: "Beautiful Death" Is Transforming Nurses' Experiences of Suffering

BACKGROUND

Nurses witness pain and distress up close and consequently experience their own suffering. A narrative study of Canadian nurses' participating in medical assistance in dying found nurses' previous witnessing of unresolved end-of-life suffering has shaped their acceptance of medical assistance in dying. Little is known about the impact of participating in medically assisted dying on nurses' suffering.

PURPOSE

To explore how nurses' overall experience of suffering is shaped by participating in medical assistance in dying.

METHODS

Qualitative secondary analysis using narrative inquiry and thematic analysis.

RESULTS

Nurses' narratives are chronologically organized addressing experiences of suffering before medical assistance in dying was a legal option and after its implementation. An overarching narrative before the availability of medical assistance in dying is (1) a culture of nurses' taken-for-granted suffering: feeling terrible. After medical assistance in dying, two key narratives describe (2) transformational feelings of a beautiful death and (3) residual discomfort. Nurses found their suffering transformed when participating in medical assistance in dying; end-of-life care was satisfying and gratifying. And yet, unanswered questions due to worries of becoming desensitized and ongoing deeper questioning remain.

CONCLUSIONS

Participating in medical assistance in dying has positively impacted nurses and starkly contrasts their previous experiences caring for those with unbearable suffering. Further research is needed to explore becoming desensitized and long-term emotional impact for nurses.

Ethics of crisis sedation: questions of performance and consent

This paper focuses on the practice of injecting patients who are dying with a relatively high dose of sedatives in response to a catastrophic event that will shortly precipitate death, something that we term 'crisis sedation.' We first present a confabulated case that illustrates the kind of events we have in mind, before offering a more detailed account of the practice. We then comment on some of the ethical issues that crisis sedation might raise. We identify the primary value of crisis sedation as allowing healthcare professionals to provide some degree of reassurance to patients, their families and the professionals who are caring for them. Next we focus on the issue of informed consent. Finally, we ask whether continuous deep sedation might be preferable to crisis sedation in scenarios where potential catastrophic events can be anticipated.

The Use of Palliative Sedation to Treat Existential Suffering: A Scoping Review on Practices, Ethical Considerations, and Guidelines

Context:

Though palliative sedation has been recognized as an acceptable practice in Canada for many years now, there is a lack of clinical research and guidelines pertaining to its use as a treatment of existential refractory symptoms in the terminally ill.

Objectives:

This scoping review aimed to survey the literature surrounding palliative sedation and existential suffering and to inform research, policy, and practice.

Methods:

To address the main research question: Is palliative sedation an acceptable intervention to treat existential refractory symptoms in adults aged 65 and older? a scoping review following Arksey and O’Malley’s framework was performed, spanning electronic databases of the peer reviewed and grey literature. Articles were screened for inclusion, and a thematic content analysis allowed for a summary of key findings.

Results:

Out of 427 search results, 71 full text articles were obtained, 20 of which were included. Out of these articles, four themes were identified as key findings. These included: (1) Ethical considerations; (2) The role of the health care provider; looking specifically at the impact on nurses; (3) The need for multidisciplinary care teams; and (4) Existential suffering’s connection to religiosity and spirituality.

Conclusion:

Palliative sedation to treat existential refractory symptoms was labelled a controversial practice. A shortage of evidence-based resources limits the current literature’s ability to inform policy and clinical practice. There is a need for both qualitative and quantitative multi-center research so health care professionals and regional-level institutions have firm roots to establish proper policy and practice.

Palliative Sedation for the Terminally Ill Patient

Palliative sedation (PS) is performed in the terminally ill patient to manage one or more refractory symptoms. Proportional PS, which means that drugs can be titrated to the minimum effective dose, is the form most widely used. From a quarter to a third of all terminally ill patients undergo PS, with a quarter of these requiring continuous deep sedation. The prevalence of PS varies according to the care setting and case mix. The most frequent refractory physical symptoms are delirium and dyspnea, but PS is also considered for existential suffering or psychological distress, which is an extremely difficult and delicate issue to deal with. Active consensus from the patient and advanced care planning is recommended for PS. The decision-making process concerning the continuation or withdrawal of other treatments is not the same as that used for PS. The practice differs totally from euthanasia in its intentions, procedures, and results. The most widely used drugs are midazolam and haloperidol for refractory delirium, but chlorpromazine and other neuroleptics are also effective. In conclusion, some patients experience refractory symptoms during the last hours or days of life and PS is a medical intervention aimed at managing this unbearable suffering. It does not have a detrimental effect on survival.

Cultivating Compassion: The Practice Experience of a Medical Assistance in Dying Coordinator in Canada

Accessing medical assistance in dying (MAiD) became legal in Canada in June, 2016. This marks a unique time in our history, as eligible persons can now opt for an assisted death and health care professionals can be involved without criminal repercussion. I used an autoethnographic approach to explore and describe my experience of implementing and coordinating a new MAiD program in a local health authority. Part I is a self-reflexive narrative based on journal entries about my immersion in this practice role over a 6 month period. In Part II, I share five emergent storylines: coming to the role (the calling), embodiment (becoming the face of), immersion in clinical practice, interactions with those seeking MAiD, and self survival (sense making). The created story and storylines shine a light on new ethical practice realities, enhance understanding about MAiD as it continues to unfold, and hopefully inspire human centered, compassionate care.

Palliative Sedation for Existential Suffering: A Systematic Review of Argument-Based Ethics Literature

CONTEXT

Although unanimity exists on using palliative sedation (PS) for controlling refractory physical suffering in end-of-life situations, using it for controlling refractory existential suffering (PS-ES) is controversial. Complicating the debate is that definitions and terminology for existential suffering are unclear, ambiguous, and imprecise, leading to a lack of consensus for clinical practice.

OBJECTIVES

To systematically identify, describe, analyze, and discuss ethical arguments and concepts underpinning the argument-based bioethics literature on PS-ES.

METHODS

We conducted a systematic search of the argument-based bioethics literature in PubMed, CINAHL, Embase^®, The Philosopher's Index, PsycINFO^®, PsycARTICLES^®, Scopus, ScienceDirect, Web of Science, Pascal-Francis, and Cairn. We included articles published in peer-reviewed journals till December 31, 2016, written in English or French, which focused on ethical arguments related to PS-ES. We used Peer Review of Electronic Search Strategies protocol, Preferred Reporting Items for Systematic Reviews and Meta-Analyses, and The Qualitative Analysis Guide of Leuven for data extraction and synthesis of themes.

RESULTS

We identified 18 articles that met the inclusion criteria. Our analysis revealed mind-body dualism, existential suffering, refractoriness, terminal condition, and imminent death as relevant concepts in the ethical debate on PS-ES. The ethical principles of double effect, proportionality, and the four principles of biomedical ethics were used in argumentations in the PS-ES debate.

CONCLUSION

There is a clear need to better define the terminology used in discussions of PS-ES and to ground ethical arguments in a more effective way. Anthropological presuppositions such as mind-body dualism underpin the debate and need to be more clearly elucidated using an interdisciplinary approach.

The Practice of Continuous Palliative Sedation in Long-Term Care for Frail Patients with Existential Suffering

Some guidelines and recommendations identify existential suffering as a potential refractory symptom for which continuous palliative sedation (CPS) can be administered under certain conditions. However, there has been little research on the characteristics of patients with existential suffering treated with CPS and the degree to which the preconditions are fulfilled. The aim of this study was to provide insight into this specific indication for CPS. Questionnaires were sent to nursing home physicians in the Netherlands, who described 314 patients. Existential suffering was a refractory symptom in 83 of the patients. For most of the patients with refractory existential suffering, other refractory symptoms were also reported, and life expectancy was seven days or less; informed consent for initiating CPS had been obtained in all cases. Consultation and intermittent sedation before the start of CPS were far less frequently reported than one would expect based on the guidelines. Multivariate analysis showed that being male, having previously requested euthanasia, having a nervous system disease, or having an other diagnosis were positively correlated with the administration of CPS for existential suffering. We conclude that more attention should be paid to the suggested preconditions and to the presence of existential suffering in male patients or patients with a nervous system disease.

[Austrian guideline for palliative sedation therapy (long version) : Results of a Delphi process of the Austrian Palliative Society (OPG)]

BACKGROUND

Palliative sedation therapy (PST) is an important and ethically accepted therapy in the care of selected palliative care patients with otherwise unbearable suffering from refractory distress. PST is increasingly used in end-of-life care. Austria does not have a standardized ethical guideline for this exceptional practice near end of life, but there is evidence that practice varies throughout the country.

OBJECTIVE

The Austrian Palliative Society (OPG) nominated a multidisciplinary working group of 16 palliative care experts and ethicists who established the national guideline on the basis of recent review work with the aim to adhere to the Europeans Association of Palliative Care's (EAPC) framework on palliative sedation therapy respecting Austrians legal, structural and cultural background.

METHODS

Consensus was achieved by a four-step sequential Delphi process. The Delphi-process was strictly orientated to the recently published EUROIMPACT-sedation-study-checklist and to the AGREE-2-tool. Additionally national stakeholders participated in the reflection of the results.

RESULTS

As a result of a rigorous consensus process the long version of the Austrian National Palliative Sedation Guideline contains 112 statements within eleven domains and is supplemented by a philosophers excursus on suffering.

CONCLUSIONS

By establishing a national guideline for palliative sedation therapy using the Delphi technique for consensus and stakeholder involvement the Austrian Palliative Society aims to ensure nationwide good practice of palliative sedation therapy. Screening for the practicability and efficacy of this guideline will be a future task.

Experiences of Family Members of Dying Patients Receiving Palliative Sedation

PURPOSE/OBJECTIVES

To describe the experience of family members of patients receiving palliative sedation at the initiation of treatment and after the patient has died and to compare these experiences over time.
.

DESIGN

Descriptive comparative study.
.

SETTING

Oncology ward at Shaare Zedek Medical Center in Jerusalem, Israel.
.

SAMPLE

A convenience sample of 34 family members of dying patients receiving palliative sedation. 
.

METHODS

A modified version of a questionnaire describing experiences of family members with palliative sedation was administered during palliative sedation and one to four months after the patient died. Descriptive statistics were used to describe the results of the questionnaire, and appropriate statistical analyses were conducted for comparisons over time.
.

MAIN RESEARCH VARIABLES

Experiences of family members and time.
.

FINDINGS

Most relatives were satisfied with the sedation and staff support. Palliative sedation was experienced as an ethical way to relieve suffering. However, one-third felt that it shortened the patient's life. An explanation of the treatment was given less than half of the time and was usually given on the same day treatment was started. This explanation was given by physicians and nurses. Many felt that they were not ready for changes in the patient's condition and wanted increased opportunities to discuss the treatment with oncology care providers. No statistically significant differences in experiences were found over time. 
.

CONCLUSIONS

Relatives' experiences of palliative sedation were generally positive and stable over time. Important experiences included timing of the initiation of sedation, timing and quality of explanations, and communication.
.

IMPLICATIONS FOR NURSING

Nurses should attempt to initiate discussions of the possible role of sedation in the event of refractory symptoms and follow through with continued discussions. The management of refractory symptoms at the end of life, the role of sedation, and communication skills associated with decision making related to palliative sedation should be a part of the core nursing curriculum. Nursing administrators in areas that use palliative sedation should enforce good nursing clinical practice as recommended by international practice guidelines, such as those of the European Association for Palliative Care.

Psychological processes of suffering of palliative care patients in Malaysia: a thematic analysis

Although suffering in palliative care has received increasing attention over the past decade, the psychological processes that underpin suffering remain relatively unexplored.

OBJECTIVE

To understand the psychological processes involved in the experiencing of suffering at the end phase of life.

METHODS

Semistructured interviews were conducted with 20 palliative care inpatients from an academic medical centre in Kuala Lumpur, Malaysia. The transcripts were thematically analysed with NVIVO9.

RESULTS

5 themes of psychological processes of suffering were generated: (1) perceptions, (2) cognitive appraisals, (3) hope and the struggles with acceptance, (4) emotions and (5) clinging. A model of suffering formation was constructed.

CONCLUSION

The findings may inform the development of mechanism-based interventions in the palliation of suffering.

An International Consensus Definition of the Wish to Hasten Death and Its Related Factors

BACKGROUND

The desire for hastened death or wish to hasten death (WTHD) that is experienced by some patients with advanced illness is a complex phenomenon for which no widely accepted definition exists. This lack of a common conceptualization hinders understanding and cooperation between clinicians and researchers. The aim of this study was to develop an internationally agreed definition of the WTHD.

METHODS

Following an exhaustive literature review, a modified nominal group process and an international, modified Delphi process were carried out. The nominal group served to produce a preliminary definition that was then subjected to a Delphi process in which 24 experts from 19 institutions from Europe, Canada and the USA participated. Delphi responses and comments were analysed using a pre-established strategy.

FINDINGS

All 24 experts completed the three rounds of the Delphi process, and all the proposed statements achieved at least 79% agreement. Key concepts in the final definition include the WTHD as a reaction to suffering, the fact that such a wish is not always expressed spontaneously, and the need to distinguish the WTHD from the acceptance of impending death or from a wish to die naturally, although preferably soon. The proposed definition also makes reference to possible factors related to the WTHD.

CONCLUSIONS

This international consensus definition of the WTHD should make it easier for clinicians and researchers to share their knowledge. This would foster an improved understanding of the phenomenon and help in developing strategies for early therapeutic intervention.

[Analysis of palliative sedation in hospitalised elderly patients: Effectiveness of a protocol]

OBJECTIVE

To measure changes in the practice of palliative sedation during agony in hospitalised elderly patients before and after the implementation of a palliative sedation protocol.

MATERIAL AND METHODS

A retrospective before-after study was performed in hospitalised patients over 65 years old who received midazolam during hospital admission and died in the hospital in two 3-month periods, before and after the implementation of the protocol. Non-sedative uses of midazolam and patients in intensive care were excluded. Patient and admission characteristics, the consent process, withdrawal of life-sustaining treatments, and the sedation process (refractory symptom treated, drug doses, assessment and use of other drugs) were recorded. Association was analysed using the Chi(2) and Student t tests.

RESULTS

A total of 143 patients were included, with no significant differences between groups in demographic characteristics or symptoms. Do not resuscitate (DNR) orders were recorded in approximately 70% of the subjects of each group, and informed consent for sedation was recorded in 91% before vs. 84% after the protocol. Induction and maintenance doses of midazolam followed protocol recommendations in 1.3% before vs 10.4% after the protocol was implemented (P=.02) and adequate rescue doses were used in 1.3% vs 11.9% respectively (P=.01). Midazolam doses were significantly lower (9.86mg vs 18.67mg, P<.001) when the protocol was used than when it was not used. Ramsay sedation score was used in 8% vs. 12% and the Palliative Care Team was involved in 35.5% and 16.4% of the cases (P=.008) before and after the protocol, respectively.

CONCLUSIONS

Use of midazolam slightly improved after the implementation of a hospital protocol on palliative sedation. The percentage of adequate sedations and the general process of sedation were mostly unchanged by the protocol. More education and further assessment is needed to gauge the effect of these measures in the future.

Limits and responsibilities of physicians addressing spiritual suffering in terminally ill patients

CONTEXT

Many patients experience spiritual suffering that complicates their physical suffering at the end of life. It remains unclear what physicians' perceived responsibilities are for responding to patients' spiritual suffering.

OBJECTIVES

To investigate U.S. physician opinions about the impact patients' unresolved spiritual struggles have on their physical pain, physicians' responsibilities for treating patients' spiritual suffering compared with patients' physical pain, and the number of patients in the past 12 months whose suffering the physician was unable to relieve to an acceptable point.

METHODS

The study was based on a mailed survey to 2016 practicing U.S. physicians from clinical specialties that care for significant numbers of dying patients.

RESULTS

Of 1878 eligible physicians, 1156 (62%) responded. Most physicians agreed that patients with unresolved spiritual struggles tend to have worse physical pain (81%) and that physicians should seek to relieve patients' spiritual suffering just as much as patients' physical pain (88%). Compared with physicians who strongly disagreed that physicians should seek to relieve patients' spiritual suffering just as much as patients' physical pain, those who strongly agreed were less likely to report being unable to relieve patients' suffering to a point the physician found acceptable (27% vs. 54% reported three or more such patients in the previous 12 months, adjusted odds ratio [95% CI] = 0.3 [0.1, 0.8]).

CONCLUSION

Most physicians believe that spiritual suffering tends to intensify physical pain and that physicians should seek to relieve such suffering. Physicians who believe they should address spiritual suffering just as much as physical pain report more success in relieving patient's suffering.

Existential encounters: nurses' descriptions of critical incidents in end-of-life cancer care

Nurses working with cancer patients in end of life care need to be prepared to encounter patients' psychosocial and spiritual distress.

AIM

The aim of this study was to describe nurses' experiences of existential situations when caring for patients severely affected by cancer.

METHODS AND SAMPLE

Nurses (registered and enrolled) from three urban in-patient hospices, an oncology clinic and a surgery clinic and a palliative homecare team were, prior to the start of a training program, invited to write down their experiences of a critical incident (CI), in which existential issues were featured.

RESULTS

Eighty-eight CIs were written by 83 nurses. The CIs were analyzed with qualitative content analysis. Two main themes were found: Encounters with existential pain experiences, which concerned facing death and facing losses; and Encountering experiences of hope, which concerned balancing honesty, and desire to live.

CONCLUSIONS

This study points out that health care professionals need to be aware of patients' feelings of abandonment in exposed situations such as patients' feelings of existential loneliness. That there are some patients that express a desire to die and this makes the nurses feel uncomfortable and difficult to confront these occurrences and its therefore important to listen to patients' stories, regardless of care organization, in order to gain access to patients' inner existential needs.

The use of palliative sedation: A comparison of attitudes of French-speaking physicians from Quebec and Switzerland

OBJECTIVE

Previous literature has suggested that laws and regulations may impact the use of palliative sedation. Our present study compares the attitudes of French-speaking physicians practicing in the Quebec and Swiss environments, where different laws are in place regarding physician-assisted suicide.

METHOD

Data were drawn from two prior studies, one by Blondeau and colleagues and another by Beauverd and coworkers, employing the same two-by-two experimental design with length of prognosis and type of suffering as independent variables. Both the effect of these variables and the effect of their interaction on Swiss and Quebec physicians' attitudes toward sedation were compared. The written comments of respondents were submitted to a qualitative content analysis and summarized in a comparative perspective.

RESULTS

The analysis of variance showed that only the type of suffering had an effect on physicians' attitudes toward sedation. The results of the Wilcoxon test indicated that the attitudes of physicians from Quebec and Switzerland tended to be different for two vignettes: long-term prognosis with existential suffering (p = 0.0577) and short-term prognosis with physical suffering (p = 0.0914). In both cases, the Swiss physicians were less prone to palliative sedation.

SIGNIFICANCE OF RESULTS

The attitudes of physicians from Quebec and Switzerland toward palliative sedation, particularly regarding prognosis and type of suffering, seem similar. However, the results suggest that physicians from Quebec could be slightly more open to palliative sedation, even though most were not in favor of this practice as an answer to end-of-life existential suffering.

Palliative Sedation

Purpose:

To describe the suggested clinical practice of palliative sedation as it is presented in the literature and discuss available guidelines for its use.

Methods:

CINAHL, PubMed, and Web of Science were searched for publications since 1997 for recommended guidelines and position statements on palliative sedation as well as data on its provision. Keywords included palliative sedation, terminal sedation, guidelines, United States, and end of life. Inclusion criteria were palliative sedation policies, frameworks, guidelines, or discussion of its practice, general or oncology patient population, performance of the intervention in an inpatient unit, for humans, and in English. Exclusion criteria were palliative sedation in children, acute illness, procedural, or burns, and predominantly ethical discussions.

Results:

Guidelines were published by American College of Physicians-American Society of Internal Medicine (2000), Hospice and Palliative Nurses Association (2003), American Academy of Hospice and Palliative Medicine (2006), American Medical Association (2008), Royal Dutch Medical Association (2009), European Association for Palliative Care (2009), National Hospice and Palliative Care Organization (2010), and National Comprehensive Cancer Network (2012). Variances throughout guidelines include definitions of the practice, indications for its use, continuation of life-prolonging therapies, medications used, and timing/prognosis.

Recommendations:

The development and implementation of institutional-based guidelines with clear stance on the discussed variances is necessary for consistency in practice. Data on provision of palliative sedation after implementation of guidelines needs to be collected and disseminated for a better understanding of the current practice in the United States.

[Palliative sedation: Current situation and areas of improvement]

OBJECTIVE

To determine the prevalence, epidemiology and registration status of palliative sedation (PS) prevalence in a teaching hospital, and to establish areas for improvement.

METHODS

A descriptive retrospective analysis was designed using the records from cancer patients who died between October and December 2010. The variables included were: epidemiological, inpatient unit, refractory symptom, drugs and dosages, and patient participation in the decision making process. The qualitative analysis followed a Delphi process: each participant received the overall performance of the group referred to as mean, median, 25th and 75th percentile. Items selected were those in which there was total or a high consensus.

RESULTS

A total of 53 deaths were identified. Just over half (51.92%) received PS. The mean age was 67.46 and 64% were males. The most frequent diagnosis was lung cancer (32.14%). Fifteen of the patient patients were in the Oncology ward, 7 in Hematology, and 4 at the Emergency Department. The PC team took part in 14 of the sedations performed. A refractory symptom was identified in 20. There were 11 cases of dyspnea and 5 cases of delirium. The mean time between admission and PS was 9.5 days. The mean duration of PS was 1.2 days, with a mean number of 2.6 drugs used. There were 20 informed consents which were all verbal. The mean time from last chemotherapy to death was 82 days. For the Delphi process, 12 oncology or palliative care health professionals were included. A consensus was reached on the minimum data to be recorded in case of PS. This list includes: selection criteria, decision-making process and the sedation evolution.

CONCLUSIONS

PS was applied in half of the patients who died due to dyspnea or delirium. Selection criteria were identified, as well as the type of PS and patient involvement in decision making process. A consensus was also reached on a minimum dataset that would help the clinician to record relevant information in PS.

Midwifing distress at end of life: Missed opportunities?

Birth and death are rites of passage, and preparation is important (Richards, 2007). Palliative care clinicians describe end of life as a meaningful stage of life filled with opportunity and mystery. However, in palliative care, we have a tendency to overlook dying as a means of spiritual awakening, and there is little understanding, and little or no demand, among palliative care patients, or in the broader culture, to learn the skills of dying.

Physicians' experiences and perspectives regarding the use of continuous sedation until death for cancer patients in the context of psychological and existential suffering at the end of life

OBJECTIVE

The use of continuous sedation until death for terminally ill cancer patients with unbearable and untreatable psychological and existential suffering remains controversial, and little in-depth insight exists into the circumstances in which physicians resort to it.

METHODS

Our study was conducted in Belgium, the Netherlands, and the UK in hospitals, PCUs/hospices, and at home. We held interviews with 35 physicians most involved in the care of cancer patients who had psychological and existential suffering and had been continuously sedated until death.

RESULTS

In the studied countries, three groups of patients were distinguished regarding the origin of their psychological and existential suffering. The first group had preexisting psychological problems before they became ill, the second developed psychological and existential suffering during their disease trajectory, and the third presented psychological symptoms that were characteristic of their disease. Before they resorted to the use of sedation, physicians reported that they had considered an array of pharmacological and psychological interventions that were ineffective or inappropriate to relieve this suffering. Necessary conditions for using sedation in this context were for most physicians the presence of refractory symptoms, a short life expectancy, and an explicit patient request for sedation.

CONCLUSIONS

Physicians in our study used continuous sedation until death in the context of psychological and existential suffering after considering several pharmacological and psychological interventions. Further research and debate are needed on how and by whom this suffering at the end of life should be best treated, taking into account patients' individual preferences.

[Palliative sedation for psycho-existential suffering]

Sedation in palliative care is generally considered as an important therapy in terminally ill patients with refractory symptoms. However the sedation of patients with intractable psycho-existential suffering is still under discussion. This paper discusses the case of a 56-year-old patient in the final phase of carcinoma of the ovaries, who required palliative sedation for refractory, mainly psycho-existential suffering. It describes the course on our ward and the difficult process of decision-making. We discuss our approach based on literature.

The perspective of the nursing staff on terminal sedation in pediatric onco-hematology: a phenomenologic-hermeneutic study

OBJECTIVE

The study was designed to explore the subjective perspective on end-of-life practices in three different groups of pediatric onco-hematologic nurses.

METHOD

In 2004-2005 each member of the nursing staff of the Pediatric Onco-Hematology Ward of the University of Padua, Italy, and the Oncology Ward and Home Assistance Module of the Giannetta Gaslini Hospital, Genoa, Italy was interviewed using a semistructured questionnaire with open questions on end-of-life procedures. The results were returned to the interviewees through group meetings. Here, we examine replies given regarding terminal sedation.

RESULTS

With regard to the nurses from Padua, common features came together in a consolidated practice. The amount of suffering and physical pain was considered an element in determining the use of sedation: "when there is atrocious suffering." Another aspect was "painful awareness," the difficulty in being able to bear the fact that the child is aware that death is imminent. The nurses from Genoa stated that the procedure was adopted mainly for three reasons: to sedate the pain, to calm the hunger for air, and to control the anguish caused by the realization that death was imminent or unavoidable. It was noted that the nursing staff of the Home Assistance Unit, Genoa found themselves in a privileged position regarding this procedure both because of the strong relationship established among child, parents, and nurse, and because of being able to take shared decisions after in-depth discussion.

SIGNIFICANCE OF RESULTS

The results enlighten the critical role of the nursing staff with respect to this procedure, given the involvement with the families and their ability to understand the child's demands and intimate expectations.

The Experiences of Suffering of Palliative Care Patients in Malaysia

A qualitative study was conducted with semi-structured interviews to explore the experiences of suffering in 20 adult palliative care inpatients of University Malaya Medical Centre. The results were thematically analyzed. Ten basic themes were generated (1) loss and change → differential suffering, (2) care dependence → dependent suffering, (3) family stress → empathic suffering, (4) disease and dying → terminal suffering, (5) health care staff encounters → interactional suffering, (6) hospital environment → environmental suffering, (7) physical symptoms → sensory suffering, (8) emotional reactions → emotional suffering, (9) cognitive reactions → cognitive suffering, and (10) spiritual reactions → spiritual suffering. An existential–experiential model of suffering was conceptualized from the analysis. This model may inform the development of interventions in the prevention and management of suffering.

[Euthanasia, assisted suicide and palliative care: a review by the Ethics Committee of the French Society of Anaesthesia and Intensive Care]

CONTEXT

Management of the end of life is a major social issue which was addressed in France by law, on April 22nd 2005. Nevertheless, a debate has emerged within French society about the legalization of euthanasia and/or assisted suicide (E/AS). This issue raises questions for doctors and most especially for anesthetists and intensive care physicians.

OBJECTIVE

To highlight, dispassionately and without dogmatism, key points taken from the published literature and the experience of countries which have legislated for E/AS.

RESULTS

The current French law addresses most of the end of life issues an intensive care physician might encounter. It is credited for imposing palliative care when therapies have become senseless and are withdrawn. However, this requirement for palliative care is generally applied too late in the course of a fatal illness. There is a great need for more education and stronger incentives for early action in this area. On the rare occasions when E/AS is requested, either by the patient or their loved-ones, it often results from a failure to consider that treatments have become senseless and conflict with patient's best interest. The implementation of E/AS cannot be reduced to a simple affirmation of the Principle of autonomy. Such procedures present genuine difficulties and the risk of drift.

CONCLUSION

We deliver a message of prudence and caution. Should we address painful end of life and moral suffering issues, by suppressing the subject, i.e. ending the patient's life, when comprehensive palliative care has not first been fully granted to all patients in need of it ?

Breaking bad news in a Southeast European population: a survey among cancer patients in Albania

OBJECTIVE

The purpose of this study was to explore the attitudes of cancer patients, their family, and community members in Albania, a post-communist country in Southeast Europe, regarding breaking bad news.

METHODS

One hundred and fifty consecutive cancer patients, 150 respective relatives, and an age-sex-residence matched sample of 150 individuals in Tirana district were interviewed from September 2009-January 2010 about attitudes related to diagnosis disclosure. Logistic regression was used to assess the association of diagnosis disclosure with demographic characteristics.

RESULTS

Community members were the most in favor, whereas the patients' relatives were the least in favor of diagnosis disclosure. Most of the patients, who were aware of their diagnosis, were not satisfied with the disclosure approach employed by the medical staff. The odds of favoring diagnosis disclosure were significantly higher among younger, male, urban, and more educated patients.

CONCLUSION

This survey identified important characteristics of cancer patients, their relatives, and a community-based sample in Albania that could predict the willingness to disclose a fatal diagnosis. Establishment of a formal training of health professionals regarding breaking bad news should be considered in order to ensure a proper approach of communicating diagnosis to cancer patients in transitional Albania.
