Assisted suicide bordering on active euthanasia

What medical conditions lead to a request for euthanasia? A rapid scoping review

Background and Aims

Euthanasia is a controversial issue related to the right to die. Although euthanasia is mostly requested by terminally sick individuals, even in societies where it is legal, it is unclear what medical conditions lead to euthanasia requests. In this scoping review, we aimed to compile medical conditions for which euthanasia has been requested or performed around the world.

Methods

The review was preferred reporting items for systematic reviews and meta-analysis for scoping reviews (PRISMA-ScR) checklist. Retrieved search results were screened and unrelated documents were excluded. Data on reasons for conducting or requesting euthanasia along with the study type, setting, and publication year were extracted from documents. Human development index and euthanasia legality were also extracted. Major medical fields were used to categorize reported reasons. Group discussions were conducted if needed for this categorization. An electronic search was undertaken in MEDLINE through PubMed for published documents covering the years January 2000 to September 2022.

Results

Out of 3323 records, a total of 197 papers were included. The most common medical conditions in euthanasia requests are cancer in a terminal phase (45.4%), Alzheimer's disease and dementia (19.8%), constant unbearable physical or mental suffering (19.8%), treatment-resistant mood disorders (12.2%), and advanced cardiovascular disorders (12.2%).

Conclusion

Reasons for euthanasia are mostly linked to chronic or terminal physical conditions. Psychiatric disorders also lead to a substantial proportion of euthanasia requests. This review can help to identify the features shared by conditions that lead to performing or requesting euthanasia.

Brain-Computer Interfaces, Completely Locked-In State in Neurodegenerative Diseases, and End-of-Life Decisions

In the future, policies surrounding end-of-life decisions will be faced with the question of whether competent people in a completely locked-in state should be enabled to make end-of-life decisions via brain-computer interfaces (BCI). This article raises ethical issues with acting through BCIs in the context of these decisions, specifically self-administration requirements within assisted suicide policies. We argue that enabling patients to end their life even once they have entered completely locked-in state might, paradoxically, prolong and uphold their quality of life.

Euthanasia and assisted suicide in neurological diseases: a systematic review

OBJECTIVE

To identify the neurological diseases for which euthanasia and assisted suicide are most frequently requested in the countries where these medical procedures are legal and the specific characteristics of euthanasia in some of these diseases, and to show the evolution of euthanasia figures.

METHODS

We conducted a systematic literature review.

RESULTS

Dementia, motor neuron disease, multiple sclerosis, and Parkinson's disease are the neurological diseases that most frequently motivate requests for euthanasia or assisted suicide. Requests related to dementia constitute the largest group, are growing, and raise additional ethical and legal issues due to these patients' diminished decision-making capacity. In some countries, the ratios of euthanasia requests to all cases of multiple sclerosis, motor neuron disease, or Huntington disease are higher than for any other disease.

CONCLUSIONS

After cancer, neurological diseases are the most frequent reason for requesting euthanasia or assisted suicide.

When the cause of death does not exist: time for the WHO to close the ICD classification gap for Medical Aid in Dying

Medical aid in dying (MAID) is a highly controversial ethical issue in the global medical community. Unfortunately, the International Classification of Diseases (ICD) of the World Health Organization (WHO) lacks coding for MAID. Therefore, no robust data adequately monitors worldwide trends that include information on diseases and conditions underlying the patients' request for assisted dying ("MAID gap"). Countries with legalised MAID observe substantial increases in cases, and likely additional countries will allow MAID in the near future. Hence, we encourage the WHO to create specific ICD codes for MAID. According to internationally established practices, a revised classification would require separate MAID-codes for (1) assisted suicide and (2) voluntary active euthanasia including supplemental codings of diseases, clusters of symptoms and function-oriented categories. By addressing these concerns, the WHO could close the "MAID gap" with new codes providing urgently necessary insights to society, public health decision-makers and regulators on this comparatively new social and medical ethical phenomenon.

Search strategy and selection criteria

Data for this Viewpoint were identified by searches of MEDLINE, PubMed, and references from relevant articles using the search terms "Medical Aid in Dying", "Assisted Dying", "Assisted suicide", "Voluntary active euthanasia", "End of life decisions" and "Cause of death statistics". Only articles and sources published in English between 1997 and 2023 were included."

Long-term development of assisted suicide in Switzerland: analysis of a 20-year experience (1999-2018)

AIMS OF THE STUDY

The legalisation of assisted suicide is one of the most debated topics in the field of medical ethics worldwide. In countries in which assisted suicide is not legal, public discussions about its approval also encompass considerations of the long-term consequences that such legalisation would bring, for example, how many people will use this option, from what conditions would they be suffering, would there be differences between male and female assisted suicide and which developments and trends could be expected if there were to be a marked increase of cases of assisted suicide over time?

METHODS

In order to answer these questions, we present the development of assisted suicide in Switzerland over a 20-year period (1999-2018; 8738 cases) using data from the Swiss Federal Statistical Office.

RESULTS

During the observation period, the number of assisted suicides rose significantly: when four 5-year periods (1999-2003, 2004-2008, 2009-2013, 2014-2018) were analysed, the number of assisted suicide cases doubled over each period compared with the preceding one (Χ = 206.7, 270.4 and 897.4; p <0.001). The percentage of assisted suicides among all deaths rose from 0.2% (1999-2003; n = 582) to 1.5% (2014-2018: n = 4820). The majority of people who chose assisted suicide were elderly, with increasing age over time (median age in 1999-2003: 74.5 years vs 2014-2018: 80 years), and with a predominance of women (57.2% vs 42.8%). The most common underlying condition for assisted suicide was cancer (n = 3580, 41.0% of all assisted suicides). Over time, assisted suicide increased similarly for all underlying conditions; however, the proportion in each disease group remained unchanged.

CONCLUSIONS

It is a matter of one's viewpoint whether the rise of assisted suicide cases should be considered alarming or not. These figures reflect an interesting social development but still do not appear to represent a mass phenomenon.

Assisted suicide in patients with cancer

Background

There are limited data on the long-term development and trends of assisted suicide (AS) among cancer patients.

Patients and methods

Using data of the Swiss Federal Statistical Office, we analyzed AS trends over an 18-year period (1999-2016; total number of cases = 6553).

Results

Among patients who underwent AS, cancer was the most common underlying disease (n = 2704, 41.3% of all AS cases). The most common cancer types were lung (14.0% of cancer-related AS cases), breast (11.0%) and prostate (10.1%). There was a slight preponderance of men compared with women (51.5% versus 48.5%). The proportion of AS cases within cancer types did not change over time. The ratio of cancer-related AS cases in relationship with all cancer-related deaths increased from 0.3% at the beginning of the study period (1999-2003) to 2.1% from 2014 to 2016 (change of age-standardized rates for men: +488%; for women: +417%). At the end of the study period (2014-2016), there were only minor differences between cancer-specific ratios, highest and lowest range: 1.1% (liver cancer) and 2.8% (breast, esophageal and lip/oral cavity/oropharynx cancer). Individuals who underwent AS because of cancer were considerably younger than those who choose AS on account of other diseases (73 years versus 80 years). The median age of people with cancer-related AS was similar to that of all cancer-related deaths (74 years): for women, the median age of cancer-related AS was 72, whereas for men it was 75. The median age at which AS took place increased over time.

Conclusions

During the study period, the proportion of people who chose cancer-related AS has approximately sextupled. However, AS among cancer patients remains rare and represents only ∼2% of all cancer-related deaths.

•

Cancer was the most common underlying disease for AS (41.3% of all AS cases).

•

The ratio of cancer-related AS to all cancer-related deaths has sextupled over time: from 0.3% (1991-2003) to 2.1% (2014-2016).

•

There were only minor differences between the cancer-specific ratios; in 2014-2016, ranges were between 1.1% and 2.8%.

•

Individuals with cancer-related AS were younger than those who choose AS due to other diseases (73 vs. 80 years).

•

The median age of people with cancer-related AS (73 years) was similar to that of all cancer-related deaths (74 years).

Death by request in Switzerland: Posttraumatic stress disorder and complicated grief after witnessing assisted suicide

Background

Despite continuing political, legal and moral debate on the subject, assisted suicide is permitted in only a few countries worldwide. However, few studies have examined the impact that witnessing assisted suicide has on the mental health of family members or close friends.

Methods

A cross-sectional survey of 85 family members or close friends who were present at an assisted suicide was conducted in December 2007. Full or partial Post-Traumatic Distress Disorder (PTSD; Impact of Event Scale–Revised), depression and anxiety symptoms (Brief Symptom Inventory) and complicated grief (Inventory of Complicated Grief) were assessed at 14 to 24 months post-loss.

Results

Of the 85 participants, 13% met the criteria for full PTSD (cut-off≥35), 6.5% met the criteria for subthreshold PTSD (cut-off≥25), and 4.9% met the criteria for complicated grief. The prevalence of depression was 16%; the prevalence of anxiety was 6%.

Conclusion

A higher prevalence of PTSD and depression was found in the present sample than has been reported for the Swiss population in general. However, the prevalence of complicated grief in the sample was comparable to that reported for the general Swiss population. Therefore, although there seemed to be no complications in the grief process, about 20% of respondents experienced full or subthreshold PTSD related to the loss of a close person through assisted suicide.

Pentobarbital in the context of possible suicides: Analysis of a Case

Pentobarbital is a barbiturate, acting as a central nervous system depressant (CNS), being used for its anticonvulsant, sedative, hypnotic and anaesthetic properties. Barbiturates were replaced by benzodiazepines, leading to a decrease in poisoning cases with these compounds. However, pentobarbital is still used in many countries as an anaesthetic in veterinary medicine. Due to its properties, this compound is sought after by people who wish to commit suicide, acquiring it on the black market. The authors present an unusual fatal pentobarbital intoxication case, in a 37 years-old male salesperson, with no known connection with the veterinary field, being more difficult to obtain this compound. Toxicological results in cardiac blood revealed the presence of pentobarbital (111mg/L), ethanol (0.94g/L), diazepam (33ng/mL), nordiazepam (50ng/mL), oxazepam (3.3ng/mL), temazepam (5.3ng/mL), and metoclopramide. No illicit drugs were detected. Pentobarbital analysis in urine and gastric content was also positive, as well as its presence in the glass powder and in the bottle residue sent to the laboratory. In the present case, it was possible to conclude that the death was a suicide due to pentobarbital intoxication in association with other depressants of the CNS (benzodiazepines and ethanol). It is important to search pentobarbital in routine toxicological analyses, since it is one of the drugs most frequently mentioned by entities defending "painless death", advising the simultaneous use of metoclopramide for emesis avoidance.

The Attitudes of Greek Physicians and Lay People on Euthanasia and Physician-Assisted Suicide in Terminally Ill Cancer Patients

The purpose of this article is to explore the attitudes of lay people and physicians regarding euthanasia and physician-assisted suicide in terminally ill cancer patients in Greece. The sample consisted of 141 physicians and 173 lay people. A survey questionnaire was used concerning issues such as euthanasia, physician-assisted suicide, and so forth. Many physicians (42.6%) and lay people (25.4%, P = .002) reported that in the case of a cardiac and/or respiratory arrest, there would not be an effort to revive a terminally ill cancer patient. Only 8.1% of lay people and 2.1% of physicians agreed on physician-assisted suicide ( P = .023). Many of the respondents, especially physicians, supported sedation but not euthanasia or physician-assisted suicide. However, many of the respondents would prefer the legalization of a terminally ill patient's hastened death.

Content of health status reports of people seeking assisted suicide: a qualitative analysis

Two right-to-die organisations offer assisted suicide in Switzerland. The specific legal situation allows assistance to Swiss and foreign citizens. Both organisations require a report of the person's health status before considering assistance. This qualitative study explored these reports filed to legal authorities after the deaths of individuals in the area of Zurich. Health status reports in the legal medical dossiers of the deceased were analysed using content analysis and Grounded Theory. From 421 cases of assisted suicide (2001-2004), 350 reports on health status were filed. Many cases contained diagnosis lists only. Other reports had more elaborate reports revealing that some physicians were aware about the patient's death wish and the intention to solicit assisted suicide. Physicians' attitudes ranged from neutral to rather depreciative. Few physicians openly referred the patient to the organisations and supported the patient's request by highlighting a history of suffering as well as reporting understanding and agreement with the patient's wish to hasten death. In the health status reports five categories could be identified. Some files revealed that physicians were aware of the death wish. The knowledge and recognition of the patient's death wish varied from no apparent awareness to strongly supportive. This variety might be due to difficulties to discuss the death wish with patients, but might also reflect the challenge to avoid legal prosecution in the country of origin. To require comparable health status reports as requirements for the right-to-die organisations might be difficult to pursue.

Collaborated death: an exploration of the Swiss model of assisted suicide for its potential to enhance oversight and demedicalize the dying process

Death, like many social problems, has become medicalized. In response to this medicalization, physician-assisted suicide (PAS) has emerged as one alternative among many at the end of life. And although the practice is currently legal in the states of Oregon and Washington, opponents still argue that PAS is unethical, is inconsistent with a physician's role, and cannot be effectively regulated. In comparison, Switzerland, like Oregon, permits PAS, but unlike Oregon, non-physicians and private organizations play a significant role in assisted death. Could the Swiss model be the answer? The following essay explores the Swiss model of assisted suicide for its potential to enhance the regulation of PAS, reduce physician involvement, and perhaps demedicalize the way we die.

The response of a Swiss university hospital's palliative care consult team to assisted suicide within the institution

In January 2006 the Centre Hospitalier Universitaire Vaudois (CHUV), a large university hospital in Lausanne, Switzerland, became the first hospital in Switzerland to allow assisted suicide (AS) in exceptional cases within its walls. However, euthanasia is illegal. This decision has posed several ethical and practical dilemmas for the hospital's palliative care consult service. To address these, the team embarked on a formal process of open dialogue amongst its members with the goal of identifying a collective response and position. This process involved meetings every 4 to 6 weeks over the course of 10 months. An iterative process unfolded. One of the principal dilemmas relates to finding a balance between the team's position against AS and the patient's autonomy and the institution's directive. Although all team members expressed opposition to AS, there were mixed opinions as to whether or not the team members should be present during the act if requested so by patients. Some thought this could be misinterpreted as complicity in the act and could send out mixed messages to the public and other health professionals about palliative care. Others felt that the team's commitment to nonabandonment obliged them to be present even if they did not provide the drug or give any advice or assistance. The implications of nonabandonment are explored, as are several other questions such as whether or not the teams are obliged to provide detailed information on AS when requested by patients.

Role of non-governmental organisations in physician assisted suicide

Could right to die organisations be part of the solution to the many ethical difficulties doctors face over assisted suicide? Stephen Ziegler and Georg Bosshard examine how two organisations in Switzerland and Oregon help people die
