Comparing end-of-life practices in different policy contexts: a scoping review

Attitudes of physicians, nurses, and the general public toward End-of-Life (EoL) decisions in European countries: an umbrella review

BACKGROUND

End-of-life (EoL) decisions represent some of the most ethically complex and emotionally charged aspects of healthcare. Understanding the attitudes of physicians, nurses, and the public toward EoL decisions is crucial for aligning care provided with the personal values and preferences of patients.

AIM

To explore the attitudes of physicians, nurses, and the general public toward EoL decisions, including the withdrawal or withholding of life-sustaining treatments, euthanasia, physician-assisted suicide (PAS), palliative sedation, and advance care planning (ACP) within European countries.

DESIGN

An umbrella review was conducted, covering the period from January 2010 to June 2024. The search strategy included Medline, CINAHL, and PsycINFO, supplemented by manual searches of reference lists of all included studies to identify additional relevant studies.

RESULTS

The search identified 587 papers, 11 of which were included in the synthesis. Of these, six addressed euthanasia and PAS, three focused on ACP, one on the withdrawal of life-sustaining treatments, and one on palliative sedation. In Europe, the general public expressed the highest level of support for EoL practices such as euthanasia and PAS, followed by nurses, while physicians often held a more cautious perspective. For withdrawal of treatment, palliative sedation, and ACP, a critical recurring theme was the need to improve communication between patients and healthcare professionals.

CONCLUSIONS

The divergence underscores the intricate complexity of navigating ethical, cultural, and professional considerations in EoL care. Effective communication serves as a cornerstone for respecting patient autonomy and ensuring that healthcare decisions align with individual values, goals and preferences.

Intentional presence and the accompaniment of dying patients

In this paper, we offer a phenomenological and hermeneutical perspective on the presence of clinicians who care for the suffering and dying patients in the context of end-of-life care. Clinician presence is described as a way of (1) being present to the patient and to oneself, (2) being in the present moment, and (3) receiving and giving a presence (in the sense of a gift). We discuss how presence is a way of restoring human beings' relational and dialogical nature. To inform a different perspective on relational ethics, we also discuss how accompaniment refers to the clinician's awareness of the human condition and its existential limits.

Physician emotional experience of communication and decision making with end-of-life patients: qualitative studies systematic review

OBJECTIVE

To explore the emotional experience of physicians in acute settings when encountering end-of-life conversations and decision making.

METHOD

Thematic synthesis of qualitative studies. Medline, PsychInfo, PubMed, BNI and CIAHL were searched from 1985 to 2021 for studies published in English. Data extraction was informed by a framework created for assessing methodological quality by Polanin, Pigott, Espelage and Grotpeter (2019) and adapted by Draper et al. (2019).

RESULTS

Of 8429 papers identified, 17 were selected for review. Two themes containing 10 subthemes described the emotional and psychological factors impacting the experience of end-of-life care, namely: a tension between desire and ability to communicate end-of-life news, and a conflict of hiding versus revealing self across several practical and emotional contexts.

CONCLUSION

Medical training is only a small factor in how well a person copes with end-of-life care and may sometimes feed negative appraisals . Lack of support from senior colleagues, fear of criticism and a sense of perceived failure were linked to lower self-efficacy in end-of-life care. Beyond learning practical skills, physicians benefit from understanding the psychological factors impacting their experience and in building self-efficacy, and observing senior colleagues effectively process strong and difficult emotions.

PRACTICAL IMPLICATIONS

Promoting personal reflection and sharing of the experiences encountered in end-of-life care, especially modelled from senior colleagues, may contribute to improvements in competence and reduce the impact of heroism, feelings of failure and avoidance in practice.

Medications and dosages used in medical assistance in dying: a cross-sectional study

BACKGROUND

There is little evidence describing the technical aspects of medical assistance in dying (MAiD) in Canada, such as medications, dosages and complications. Our objective was to describe clinical practice in providing MAiD in Ontario and Vancouver, Canada, and explore relations between medications used, time until death and complications.

METHODS

We conducted a retrospective cohort study of a sample of adult (age ≥ 18 yr) patients who received MAiD in Ontario between 2016 and 2018, and patients who received MAiD in 1 of 3 Canadian academic hospitals (in Hamilton and Ottawa, Ontario, and Vancouver, British Colombia) between 2019 and 2020. We used de-identified data for 2016-2018 from the Office of the Chief Coroner for Ontario MAiD Database and chart review data for 2019-2020 from the 3 centres. We used multivariable parametric survival analysis to identify relations between medications, dosages and time from procedure start until death.

RESULTS

The sample included 3557 patients (1786 men [50.2%] and 1770 women [49.8%] with a mean age of 74 [standard deviation 13] yr). The majority of patients (2519 [70.8%]) had a diagnosis of cancer. The medications most often used were propofol (3504 cases [98.5%]), midazolam (3251 [91.4%]) and rocuronium (3228 [90.8%]). The median time from the first injection until death was 9 (interquartile range 6) minutes. Standard-dose lidocaine (40-60 mg) and high-dose propofol (> 1000 mg) were associated with prolonged time until death (prolonged by a median of 1 min and 3 min, respectively). Complications occurred in 41 cases (1.2%), mostly related to venous access or need for administration of a second medication.

INTERPRETATION

In a large sample of patients who died with medical assistance, certain medications were associated with small differences in time from injection to death, and complications were rare. More research is needed to identify the medication protocols that predict outcomes consistent with patient and family expectations for a medically assisted death.

Understanding Experiences of Moral Distress in End-of-Life Care Among US and UK Physician Trainees: a Comparative Qualitative Study

BACKGROUND

Moral distress is a state in which a clinician cannot act in accordance with their ethical beliefs because of external constraints. Physician trainees, who work within rigid hierarchies and who lack clinical experience, are particularly vulnerable to moral distress. We examined the dynamics of physician trainee moral distress in end-of-life care by comparing experiences in two different national cultures and healthcare systems.

OBJECTIVE

We investigated cultural factors in the US and the UK that may produce moral distress within their respective healthcare systems, as well as how these factors shape experiences of moral distress among physician trainees.

DESIGN

Semi-structured in-depth qualitative interviews about experiences of end-of-life care and moral distress.

PARTICIPANTS

Sixteen internal medicine residents in the US and fourteen junior doctors in the UK.

APPROACH

The work was analyzed using thematic analysis.

KEY RESULTS

Some drivers of moral distress were similar among US and UK trainees, including delivery of potentially inappropriate treatments, a poorly defined care trajectory, and involvement of multiple teams creating different care expectations. For UK trainees, healthcare team hierarchy was common, whereas for US trainees, pressure from families, a lack of guidelines for withholding inappropriate treatments, and distress around physically harming patients were frequently cited. US trainees described how patient autonomy and a fear of lawsuits contributed to moral distress, whereas UK trainees described how societal expectations around resource allocation mitigated it.

CONCLUSION

This research highlights how the differing experiences of moral distress among US and UK physician trainees are influenced by their countries' healthcare cultures. This research illustrates how experiences of moral distress reflect the broader culture in which it occurs and suggests how trainees may be particularly vulnerable to it. Clinicians and healthcare leaders in both countries can learn from each other about policies and practices that might decrease the moral distress trainees experience.

Assistance in dying across borders: How the transnational circulations of persons, terms and themes influence the construction of a public problem

Assistance in dying has become a transnational issue debated and lawfully practiced in several jurisdictions around the world. This article focuses on persons, terms and themes that circulate from one context authorizing assistance in dying to another. Building on Joseph Gusfield's concepts of judgment, ownership and responsibility, we explore how national debates on assistance in dying draw on transnational circulations which are instrumental in the construction of this issue as a public problem. Adopting a transnational lens shows that local public problems of assistance in dying should not be apprehended in isolation nor compared as independent contexts.

Assistance in dying: Conditions for international comparison

This special issue of Death Studies interrogates conditions for conducting international comparisons of assistance in dying regimes, and of related discourses and practices. To do so, it provides comparative social sciences and humanities perspectives on assistance in dying. In this editorial introduction, we first trace the origin of this special issue to the symposium held in 2018 in Lausanne, Switzerland. We then offer a short exploration of how assistance in dying regimes have been compared in the literature. Finally, we identify key conditions for conducting international comparisons of assistance in dying based on the articles presented in this issue of Death Studies.

International changes in end-of-life practices over time: a systematic review

Background

End-of-life policies are hotly debated in many countries, with international evidence frequently used to support or oppose legal reforms. Existing reviews are limited by their focus on specific practices or selected jurisdictions. The objective is to review international time trends in end-of-life practices.

Methods

We conducted a systematic review of empirical studies on medical end-of-life practices, including treatment withdrawal, the use of drugs for symptom management, and the intentional use of lethal drugs. A search strategy was conducted in MEDLINE, EMBASE, Web of Science, Sociological Abstracts, PAIS International, Worldwide Political Science Abstracts, International Bibliography of the Social Sciences and CINAHL. We included studies that described physicians’ actual practices and estimated annual frequency at the jurisdictional level. End-of-life practice frequencies were analyzed for variations over time, using logit regression.

Results

Among 8183 references, 39 jurisdiction-wide surveys conducted between 1990 and 2010 were identified. Of those, 22 surveys used sufficiently similar research methods to allow further statistical analysis. Significant differences were found across surveys in the frequency of treatment withdrawal, use of opiates or sedatives and the intentional use of lethal drugs (X² > 1000, p < 0.001 for all). Regression analyses showed increased use of opiates and sedatives over time (p < 0.001), which could reflect more intense symptom management at the end of life, or increase in these drugs to intentionally cause patients’ death.

Conclusion

The use of opiates and sedatives appears to have significantly increased over time between 1990 and 2010. Better distinction between practices with different legal status is required to properly interpret the policy significance of these changes. Research on the effects of public policies should take a comprehensive look at trends in end-of-life practice patterns and their associations with policy changes.

Medical end-of-life practices among Canadian physicians: a pilot study

BACKGROUND

Medical end-of-life practices are hotly debated in Canada, and data from other countries are used to support arguments. The objective of this pilot study was twofold: to adapt and validate a questionnaire designed to measure the prevalence of these practices in Canada and the underlying decision-making process, and to assess the feasibility of a nationally representative study.

METHODS

In phase 1, questionnaires from previous studies were adapted to the Canadian context through consultations with a multidisciplinary committee and based on a scoping review. The modified questionnaire was validated through cognitive interviews with 14 physicians from medical specialties associated with a higher probability of being involved with dying patients recruited by means of snowball sampling. In phase 2, we selected a stratified random sample of 300 Canadian physicians in active practice from a national medical directory and used the modified tailored method design for mail and Web surveys. There were 4 criteria for success: modified questions are clearly understood; response patterns for sensitive questions are similar to those for other questions; respondents are comparable to the overall sampling frame; and mean questionnaire completion time is less than 20 minutes.

RESULTS

Phase 1: main modifications to the questionnaire were related to documentation of all other medical practices (including practices intended to prolong life) and a question on the proportionality of drugs used. The final questionnaire contained 45 questions in a booklet style. Phase 2: of the 280 physicians with valid addresses, 87 (31.1%) returned the questionnaire; 11 of the 87 declined to participate, for a response rate of 27.1% (n = 76). Most respondents (64 [84%]) completed the mail questionnaire. All the criteria for success were met.

INTERPRETATION

It is feasible to study medical end-of-life practices, even for practices that are currently illegal, including the intentional use of lethal drugs. Results from this pilot study support conducting a large national study, but additional strategies would be necessary to improve the response rate.
