The involvement of cancer patients in the four stages of decision-making preceding continuous sedation until death: A qualitative study

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.

Shared decision-making in palliative cancer care: A systematic review and metasynthesis

BACKGROUND

Shared decision-making is a key element of person-centred care and promoted as the favoured model in preference-sensitive decision-making. Limitations to implementation have been observed, and barriers and limitations, both generally and in the palliative setting, have been highlighted. More knowledge about the process of shared decision-making in palliative cancer care would assist in addressing these limitations.

AIM

To identify and synthesise qualitative data on how people with cancer, informal carers and healthcare professionals experience and perceive shared decision-making in palliative cancer care.

DESIGN

A systematic review and metasynthesis of qualitative studies. We analysed data using inductive thematic analysis.

DATA SOURCES

We searched five electronic databases (MEDLINE, EMBASE, PsycINFO, CINAHL and Scopus) from inception until June 2023, supplemented by backward searches.

RESULTS

We identified and included 23 studies, reported in 26 papers. Our analysis produced four analytical themes; (1) Overwhelming situation of 'no choice', (2) Processes vary depending on the timings and nature of the decisions involved, (3) Patient-physician dyad is central to decision-making, with surrounding support and (4) Level of involvement depends on interactions between individuals and systems.

CONCLUSION

Shared decision-making in palliative cancer care is a complex process of many decisions in a challenging, multifaceted and evolving situation where equipoise and choice are limited. Implications for practice: Implementing shared decision-making in clinical practice requires (1) clarifying conceptual confusion, (2) including members of the interprofessional team in the shared decision-making process and (3) adapting the approach to the ambiguous, existential situations which arise in palliative cancer care.

The Mapping of Influencing Factors in the Decision-Making of End-of-Life Care Patients: A Systematic Scoping Review

Decisions in end-of-life care are influenced by several factors, many of which are not identified by the decision maker. These influencing factors modify important decisions in this scenario, such as in decisions to adapt to therapeutic support. This presented scoping review aims to map the factors that influence end-of-life care decisions for adult and older adult patients, by a scoping review. The review was carried out in 19 databases, with the keyword 'clinical decision-making' AND 'terminal care' OR 'end-of-life care' and its analogues, including publications from 2017 to 2022. The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews. The search resulted in 3474 publications, where the presence of influencing factors in end-of-life decision-making for adults and the elderly was applied as a selection criterion. Fifty-four (54) of them were selected, which means 1.5% of all the results. Among the selected publications, 89 influencing factors were found, distributed in 54 (60.6%) factors related to the health team, 18 (20.2%) to patients, 10 (11.2%) related to family or surrogates and 7 (7.8%) factors related to the decision environment. In conclusion, we note that the decision-making in end-of-life care is complex, mainly because there is an interaction of different characters (health team, patient, family, or surrogates) with a plurality of influencing factors, associated with an environment of uncertainty and that result in a critical outcome, with a great repercussion for the end of life, making it imperative the recognition of these factors for more competent and safe decision-making.

An analysis of the experiences of bereaved relatives and health care providers following palliative sedation: a study protocol for a qualitative international multicenter case study

BACKGROUND

Patients at the end-of-life may experience refractory symptoms of which pain, delirium, vomiting and dyspnea are the most frequent. Palliative sedation can be considered a last resort option to alleviate one or more refractory symptoms. There are only a limited number of (qualitative) studies exploring the experiences of relatives of sedated patients and their health care professionals (HCPs). The aims of this study protocol are: 1) to elicit the experiences of bereaved relatives and health care professionals of patients treated with palliative sedation and 2) to explore the understanding of the decision-making process to start palliative sedation across care settings in 5 European countries.

METHODS

This study protocol is part of the larger HORIZON 2020 Palliative Sedation project. Organisational case study methodology will be used to guide the study design. In total, 50 cases will be conducted in five European countries (10 per country). A case involves a semi-structured interview with a relative and an HCP closely involved in the care of a deceased patient who received some type of palliative sedation at the end-of-life. Relatives and health care professionals of deceased patients participating in a linked observational cohort study of sedated patients cared for in hospital wards, palliative care units and hospices will be recruited. The data will be analyzed using a framework analysis approach. The first full case will be analyzed by all researchers after being translated into English using a pre-prepared code book. Afterwards, bimonthly meetings will be organized to coordinate the data analysis.

DISCUSSION

The study aims to have a better understanding of the experiences of relatives and professional caregivers regarding palliative sedation and this within different settings and countries. Some limitations are: 1) the sensitivity of the topic may deter some relatives from participation, 2) since the data collection and analysis will be performed by at least 5 different researchers in 5 countries, some differences may occur which possibly makes it difficult to compare cases, but using a rigorous methodology will minimize this risk.

Sedation in specialized palliative care: A cross-sectional study

Background

Palliative sedation is used to relieve refractory symptoms and is part of clinical practice in Sweden. Yet we do not know how frequently this practice occurs, how decision-making takes place, or even which medications are preferentially used.

Objectives

To understand the current practice of palliative sedation in Sweden.

Methods

We conducted a retrospective cross-sectional medical record-based study. For 690 consecutive deceased patients from 11 of 12 specialized palliative care units in the southernmost region of Sweden who underwent palliative sedation during 2016, we collected data on whether the patient died during sedation and, for sedated patients, the decision-making process, medication used, and depth of sedation.

Results

Eight percent of patients were sedated. Almost all (94%) were given midazolam, sometimes in combination with propofol. The proportions of sedation were similar in the patient groups with and without cancer. The largest proportion of the sedated patients died in inpatient care, but 23% died at home, with specialized palliative home care. Among the patients with a decision to sedate, 42% died deeply unconscious, while for those without such a decision the corresponding figure was 16%. In only one case was there more than one physician involved in the decision to use palliative sedation.

Conclusion

8% of patients in specialized palliative care received palliative sedation, which is lower than international measures but much increased compared to an earlier Swedish assessment. The level of consciousness achieved often did not correspond to the planned level; this, together with indications of a scattered decision process, shows a need for clear guidelines.

Physicians’ Experiences and Perceptions of Environmental Factors Affecting Their Practices of Continuous Deep Sedation until Death: A Secondary Qualitative Analysis of an Interview Study

As previous research has paid little attention to environmental factors affecting the practice of continuous deep sedation until death (CDS), we aimed to explore these using physicians’ experiences and perceptions. We performed an interpretative thematic analysis of primary data from a qualitative interview study conducted from February to May 2019 in Belgium with 47 physicians. Structural factors were identified: the lack of professional and/or technical support in monitoring sedated patients; the use of guidelines in team contexts; the time constraints for treating individual patients and work pressure; the structural knowledge gap in medical education; the legal context for assisted dying; and the lack of a clear legal context for CDS. Cultural factors were identified: the moral reservations of care teams and/or institutions towards CDS; the presence of a palliative care culture within care teams and institutions; the culture of fear of making clinical errors regarding CDS among a group of physicians; the professional stigma of performing assisted dying among some of the physician population; the different understandings of CDS in medical and policy fields; and the societal taboo around suffering at the end of life and natural death. To conclude, improving CDS practice requires a whole-system approach considering environmental factors.

The Decision-Making Process for Palliative Sedation for Patients with Advanced Cancer-Analysis from a Systematic Review of Prospective Studies

BACKGROUND

The involvement of patients in decision making about their healthcare plans is being emphasized. In the context of palliative sedation, it is unclear how these decisions are made and who are involved in. The aim of the study is to understand how this decision-making is taken.

METHOD

Information from a systematic review on clinical aspects of palliative sedation prospective studies were included. PubMed, CINAHL, Cochrane, MEDLINE, and EMBASE were searched (January 2014-December 2019). Data extraction and analysis regarded: (a) When and by whom the decision-making process is initiated; (b) patient involvement; (c) family involvement and (d) healthcare involvement.

RESULTS

Data about decision making were reported in 8/10 included articles. Palliative sedation was reported in 1137 patients (only 16 of them were non-cancer). Palliative sedation was introduced by the palliative care team during the disease process, at admission, or when patients experienced refractory symptoms. Only two studies explicitly mentioned the involvement of patients in decision making. Co-decision between families and the regular health care professionals was usual, and the health care professionals involved had been working in palliative care services.

CONCLUSION

Patient participation in decision making appeared to be compromised by limited physical or cognitive capacity and family participation is described. The possibility of palliative sedation should be discussed earlier in the disease process.

Patient participation in shared decision-making in palliative care - an integrative review

BACKGROUND

Shared decision-making is a process where the decisions regarding patients' care are done in collaboration with the patient, the patient's family and a healthcare professional or an interdisciplinary team. Shared decision-making is considered to be a part of patient centred care, and it enables patient autonomy which is a cornerstone of palliative care. In the past, research on the experiences of palliative care patients' participation in shared decision-making involving a nurse has been limited as the focus has mainly been on specific medical interventions, rather than holistic palliative care.

OBJECTIVES

To synthesise research findings on patient participation in shared decision-making in palliative care.

RESEARCH DESIGN

An integrative literature review.

METHODS

The literature search was conducted by searching computerised databases (CINAHL, PubMed, PsychINFO and COCHRANE). The search resulted in 12 articles. The quality of the included articles was evaluated with JBI checklist, and the data analysis was done using inductive content analysis. Reporting was done according to a PRISMA checklist.

FINDINGS

Patients do participate in shared decision-making and desire to participate in everyday nursing care decisions, treatment-related medical decisions and end-of-life decisions. The prerequisites for patient participation in shared decision-making are interdisciplinary teamwork, open communication, good patient-healthcare professional relationship, a favourable environment and mutual information.

CONCLUSION

Palliative care patients do participate and desire to participate in decisions that cover a much broader range of topics than just medical interventions and this should be addressed in future research and in practise. The main responsibility for successful patient participation in shared decision-making lies with the healthcare professionals and the organisations providing palliative care. There is a need to conduct more research from the patient's perspective and explore the meaning of participating in shared decision-making from the patient's point of view.

A systematic review of quality improvement initiatives for continuous sedation until death

BACKGROUND

Extensive debate surrounds the practice of continuous sedation until death within end-of-life care.

AIM

To provide insight into existing initiatives to support the practice of continuous sedation until death and assess their feasibility and effectiveness.

DESIGN

Systematic review and narrative synthesis, registered on PROSPERO (CRD42020149630).

DATA SOURCES

Records were searched through MEDLINE, EMBASE, CENTRAL, CINAHL, and Web of Science from inception to April 16 2020. Peer-reviewed studies reporting original data on initiatives to support the practice of continuous sedation were included for review.

RESULTS

Twenty-one studies met the criteria and were included. Initiatives were focused on assessment tools of consciousness and discomfort (9), the use of guidelines and protocols (8), and expert consultation (3). All initiatives were reported as useful, acceptable, and feasible. Studies on the use of monitoring devices showed that a small proportion of patients were found to be awake, despite the patient being unresponsive according to the observer-based sedation scales. However, the wide range of values of these monitoring devices for comfortable and adequately sedated patients seems to hamper its overall implementation in daily clinical practice. Physicians reported changes in practice conform to guideline recommendations but the shift was modest at best. Expert consultation was regarded as supportive when sufficient expertise is lacking and helpful in avoiding possibly unnecessary sedations.

CONCLUSIONS

The reviewed initiatives may contribute to improvement of continuous sedation until death, though their evidence base is rather limited. More insight is needed into their feasibility, preconditions for effective implementation and impact in actual practice.

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.

Clinical and ethical aspects of palliative sedation with propofol-A retrospective quantitative and qualitative study

BACKGROUND

The anesthetic propofol is often mentioned as a drug that can be used in palliative sedation. The existing literature of how to use propofol in palliative sedation is scarce, with lack of information about how propofol could be initiated for palliative sedation, doses and treatment outcomes.

AIM

To describe the patient population, previous and concomitant medication, and clinical outcome when propofol was used for palliative sedation.

METHODS

A retrospective study with quantitative and qualitative data. All patients who during a 4.5-year period received propofol for palliative sedation at the Department of palliative medicine, Akershus University Hospital, Norway were included.

RESULTS

Fourteen patients were included. In six patients the main indication for palliative sedation was pain, in seven dyspnoea and in one delirium. In eight of these cases propofol was chosen because of the pharmacokinetic properties (rapid effect), and in the remaining cases propofol was chosen because midazolam in spite of dose titration failed to provide sufficient symptom relief. In all patients sedation and adequate symptom control was achieved during manual dose titration. During the maintenance phase three of 14 patients had spontaneous awakenings. At death, propofol doses ranged from 60 to 340 mg/hour.

CONCLUSIONS

Severe suffering at the end of life can be successfully treated with propofol for palliative sedation. This can be performed in palliative medicine wards, but skilled observation and dose titration throughout the period of palliative sedation is necessary. Successful initial sedation does not guarantee uninterrupted sedation until death.

EDITORIAL COMMENT

In palliative care, some patients at the end of life can reach a stage where there have been maximal analgesic and or anxiolytic treatments though without achieving comfort in the awake state. This report describes and discusses use of propofol in these infrequent cases to relieve suffering as part of palliative care.

Reflections on palliative sedation

'Palliation sedation' is a widely used term to describe the intentional administration of sedatives to reduce a dying person's consciousness to relieve intolerable suffering from refractory symptoms. Research studies generally focus on either 'continuous sedation until death' or 'continuous deep sedation'. It is not always clear whether instances of secondary sedation (i.e. caused by specific symptom management) have been excluded. Continuous deep sedation is controversial because it ends a person's 'biographical life' (the ability to interact meaningfully with other people) and shortens 'biological life'. Ethically, continuous deep sedation is an exceptional last resort measure. Studies suggest that continuous deep sedation has become 'normalized' in some countries and some palliative care services. Of concern is the dissonance between guidelines and practice. At the extreme, there are reports of continuous deep sedation which are best described as non-voluntary (unrequested) euthanasia. Other major concerns relate to its use for solely non-physical (existential) reasons, the under-diagnosis of delirium and its mistreatment, and not appreciating that unresponsiveness is not the same as unconsciousness (unawareness). Ideally, a multiprofessional palliative care team should be involved before proceeding to continuous deep sedation. Good palliative care greatly reduces the need for continuous deep sedation.
