Associations of end-of-life preferences and trust in institutions with public support for assisted suicide: evidence from nationally representative survey data of older adults in Switzerland

Preparing for the end-of-life: public attitudes towards advance directives and assisted suicide in Switzerland

BACKGROUND

Despite public support for assisted suicide (AS) and advance directives (AD), no studies have established whether individuals express interest in both procedures. This study investigates the relationship between AD completion and attitudes toward assisted suicide, examining whether Swiss older adults inclined toward AD also demonstrate positive attitudes toward AS.

METHOD

Data from 1,523 participants aged 58 and older were collected through the Swiss component of the representative Survey on Health, Ageing, and Retirement in Europe (SHARE) for 2019/2020. Participants were asked if they had completed AD. Attitudes toward AS were assessed using three key questions: support for AS, consideration of it, and membership in a right-to-die organization. Probit regression models analyzed the associations, considering various social, health, and regional characteristics.

RESULTS

Overall, 42% of the sample had completed AD. Additionally, 81% supported legal access to AS, 63% considered asking for it, and 9% were members of a right-to-die association. Among members of a right-to-die a, 89% had completed an AD. Respondents who had completed AD were more likely to support AS (p < 0.001), consider it (p < 0.001), and be members of a right-to-die organization (p < 0.001).

CONCLUSIONS

The study reveals an association between completing AD and supporting attitudes toward AS among older adults in Switzerland, highlighting how the desire to control end-of-life experiences can drive interest in both procedures. Future developments in end-of-life care planning should consider incorporating discussions and documentation of AD and AS together.

Knowledge of and Preferences for Medical Aid in Dying

Importance

Medical aid in dying (MAID) is legal in jurisdictions covering more than one-fifth of the US population and has been used by a largely White, educated population. The extent to which knowledge of MAID and preferences for personal use align with patterns of use is unknown.

Objective

To evaluate knowledge among US adults of the legal status of MAID as well as interest in using MAID.

Design, Setting, and Participants

This cross-sectional, self-report online survey study used a national Prime Panels-based sample of US adults recruited between July 16 and August 10, 2024. A total of 3227 respondents aged 18 years or older from all US states and Washington, DC, were included. Individuals from states with legal MAID, aged 60 years or older, and members of racial and ethnic minority groups were oversampled.

Main Outcomes and Measures

Knowledge of the legality of MAID in the US and in respondents' state of residence as well as potential interest in future use of MAID. Descriptive statistics and χ2 tests were used to examine associations by demographic characteristics and place of residence.

Results

Of 3227 respondents (mean [SD] age, 55.7 [17.4] years; 1839 women [57.0%]), 1654 (51.3%) did not know if MAID was legal the US, and 1638 (50.8%) did not know if MAID was legal in their state. Respondents in states where MAID is legal were more likely to know that MAID is legal in the US compared with those in states where MAID is not legal (728 of 2164 [33.6%] vs 216 of 1063 [20.3%]; P < .001). Across all respondents, 1420 (44.0%), including 96 of 222 Asian respondents (43.2%), 206 of 605 Black respondents (34.0%), and 129 of 308 Hispanic respondents (41.9%), reported they would definitely or probably consider MAID if they received a diagnosis of a terminal illness.

Conclusions and Relevance

In this online survey study of US adults, substantial interest in using MAID as well as significant knowledge gaps regarding the legality of MAID were reported. These findings highlight the need for public education, policy initiatives, and patient-clinician discussions to ensure equitable access to patient-centered end-of-life options and informed decision-making.

Cross-sectional survey on public attitudes and factors related to physician-assisted dying in Taiwan

OBJECTIVE

To examine the public's stance on physician-assisted dying (PAD) in Taiwan across different PAD scenarios and identify demographic and psychosocial factors associated with the levels of support.

DESIGN

Cross-sectional survey design. Independent variables included individual sociodemographic characteristics, healthcare professionals, perceived quality of life, formal caregiver experience, Patient Right to Autonomy Act (PRAA) awareness and advance care planning (ACP) preparedness.

SETTING

An online survey of the general population in Taiwan was conducted in 2022.

PARTICIPANTS

A total of 3922 Taiwanese adults who completed all survey questions.

OUTCOME MEASURES

Agreement levels with PAD in three scenarios: terminal illnesses, unbearable non-terminal pain and severe cognitive impairments. Multivariate logistic regression was used to examine agreement with each PAD scenario as separate dependent variables in the first three models and overall agreement across all scenarios as the dependent variable in the fourth model.

RESULTS

High levels of public support for PAD were observed, with 86.2% supporting PAD for terminal illnesses, 79.2% for unbearable non-terminal pain and 72.6% for severe cognitive impairments. Support for PAD was associated with factors including younger age, male gender, lack of religious affiliation, a non-healthcare professional background, employment as a formal caregiver, lack of awareness of PRAA and higher preparedness in ACP.

CONCLUSIONS

The results indicate a potential cultural shift in Taiwan towards greater emphasis on individual autonomy in end-of-life decisions. There appears to be significant public support for developing legal frameworks in favour of PAD, carefully considering the psychosocial factors that highlight the importance of individual rights in end-of-life care.

Attitudes toward Medically Assisted Dying Among the General Public in Slovenia

The aim of this study was to explore public attitudes toward medically assisted dying, focusing on the role of socio-demographic factors, mental health conditions, and personal experiences. Data were collected via an online panel in Slovenia, which consisted of 567 participants (53.1% men) aged 18 years and older. The majority of respondents supported medically assisted dying for terminally ill individuals (76.4%) and expressed willingness to support a loved one's decision (72.8%). The analysis indicated that psychosocial factors and personal experiences predict attitudes toward medically assisted dying. In particular, women, individuals with poorer physical and psychological health and individuals in better environmental conditions were more likely to have positive attitudes. In contrast, individuals who had experienced the loss of a loved one were more likely to oppose it. These findings suggest the need for further research to deepen understanding of the factors that predict attitudes toward medically assisted dying.

Determinants of suicidal history before assisted versus self-initiated suicide late in life: an observational study

BACKGROUND

Older adults are at risk of assisted and self-initiated suicide. The links between prior attempts and assisted suicide in the elderly have not been investigated. Hence, we aimed to investigate and describe the occurrence, timing and determinants of suicide attempts prior to assisted and self-initiated suicide.

METHODS

We developed a retrospective study of all assisted and self-initiated suicides among people over 65 years in the canton of Geneva, Switzerland, for a 10-year period (2010-2019). Cases were identified by cross-referencing hospitals' routinely collected electronic data and a forensic report database. Cases were characterised in terms of sociodemographic factors, mental health disorders, main comorbidities, temporal sequence, methods of injury, medical complications and disclosure rates of previous attempts. The study used descriptive statistics.

RESULTS

A total of 26 of 497 (5.2%) and 20 of 149 (13.4%) older adults had made previous attempts before assisted and self-initiated suicide, respectively. More than half of them had made a single attempt, mostly by medication poisoning, sometimes more than 10 years before dying. Individuals who made two attempts were significantly more represented among the assisted suicide decedents. One self-initiated suicide decedent and half of the assisted suicide cases had disclosed that they had considered suicide. Individual characteristics were similar, except for assisted suicide decedents, who were eight years older than self-initiated suicide decedents. Almost all the individuals had mental disorders. Depression, anxiety and chronic pain were particularly prevalent among decedents of assisted suicide. The substantial representation of women in both groups may be an indication of their vulnerability, possibly related to chronic pain and life stressors.

CONCLUSIONS

Our results show commonalities between older assisted and self-initiated suicide decedents who made an attempt (s) before suicide. Further research is needed to demonstrate the overlap between the determinants of assisted suicide and other forms of suicidality and to support a suicide prevention strategy applicable to both types of suicide.

Wish to Die Among Residents of Swiss Long-Term Care Facilities: A Multisite Cross-Sectional Study

OBJECTIVES

The wish to die (WTD) in persons near the end of life is a clinically important, ethically and practically complex phenomenon as demonstrated by the intense debates on assisted dying legislation around the world. Despite global aging and increasing institutionalization in old age, WTD among residents of long-term care facilities (LTCF) is underexplored. We aimed to assess the prevalence of WTD and identify its predictors in older LTCF residents.

DESIGN

Multisite cross-sectional observational study.

SETTING AND PARTICIPANTS

31 LTCF in the 3 major linguistic regions of Switzerland, including residents 75 years or older, admitted to the LTCF 4 to 10 months before the study, without severe cognitive impairment.

METHODS

Between February 2013 and June 2017, trained research staff interviewed residents to assess WTD using 2 validated instruments and collected information on potential predictors, including depressive symptoms, anxiety, demoralization, feeling to be a burden, spiritual distress, symptom burden, multimorbidity, and drug use. Demographic data were obtained by chart review. Descriptive statistics as well as univariate and multivariate regression analyses were performed.

RESULTS

From 427 eligible residents, 101 were excluded, 46 refused, and 280 were included in the study (acceptance rate 85.9%). In general, residents readily and openly addressed the topic of WTD. The prevalence of WTD was 16.0% and 16.2% according to the 2 instruments, with all but 1 of the residents expressing a passive WTD. The strongest independent predictors for a WTD were depressive symptoms (OR 7.45 and 5.77 for the 2 WTD assessment instruments) and demoralization (OR 2.62 and 3.66).

CONCLUSIONS AND IMPLICATIONS

The WTD is a relevant concern affecting approximately 1 in 6 LTCF residents. Further research is needed to investigate which interventions could best address the potentially modifiable factors that were associated with the WTD in this specific setting and population.

Dimensions of end-of-life preferences in the Swiss general population aged 55+

BACKGROUND

understanding end-of-life preferences in the general population and how they are structured in people's minds is essential to inform how to better shape healthcare services in accordance with population expectations for their end of life and optimise communication on end-of-life care issues.

OBJECTIVE

explore key dimensions underlying end-of-life preferences in a nationally representative sample of adults aged 55 and over in Switzerland.

METHODS

respondents (n = 2,514) to the Swiss version of the Survey of Health, Ageing and Retirement in Europe assessed the importance of 23 end-of-life items on a 4-point Likert scale. The factorial structure of the underlying end-of-life preferences was examined using exploratory structural equation modelling.

RESULTS

four dimensions underlying end-of-life preferences were identified: a medical dimension including aspects related to pain management and the maintenance of physical and cognitive abilities; a psychosocial dimension encompassing aspects related to social and spiritual support; a control dimension addressing the need to achieve some control and to put things in order before death; and a burden dimension reflecting wishes not to be a burden to others and to feel useful to others.

CONCLUSION

highlighting the multi-dimensionality of end-of-life preferences, our results reaffirm the importance of a holistic and comprehensive approach to the end of life. Our results also provide a general framework that may guide the development of information and awareness campaigns on end-of-life care issues in the general population, informational materials and guidelines to support healthy individuals in end-of-life thinking and planning, and advance directive templates appropriate for healthy individuals.

The views of Aotearoa/New Zealand adults over 60 years regarding the End of Life Choice Act 2019

This study described the views of older New Zealand adults toward assisted dying and specifically the End of Life Choice Act (2019), an Act making assisted dying legal. An anonymous postal and online survey of 636 adults 60 years and older was conducted. The majority of respondents did not support legalization (85.7%), while 8.8% were in favor (5.5% did not specify a view). Weighted binary logistic regression indicated that the odds of support for legalization were lower in those respondents with a religious affiliation (OR = .020, S.E. = 0.60, p = .00), and there were 2.66 times greater odds in those identifying as male (S.E. = 0.34, p = .005). On the other hand, those respondents under 65 years had increased odds of supporting legalization (OR = 1.89, S.E. = .029, p = .045). Results indicate that most participants were concerned about potential abuses and coercive practices if assisted dying became legally available in New Zealand.
