Artificial intelligence (AI) systems are quickly gaining ground in healthcare and clinical decision-making. However, it is still unclear in what way AI can or should support decision-making that is based on incapacitated patients’ values and goals of care, which often requires input from clinicians and loved ones. Although the use of algorithms to predict patients’ most likely preferred treatment has been discussed in the medical ethics literature, no example has been realised in clinical practice. This is due, arguably, to the (...) lack of a structured approach to the epistemological, ethical and pragmatic challenges arising from the design and use of such algorithms. The present paper offers a new perspective on the problem by suggesting that preference predicting AIs be viewed as sociotechnical systems with distinctive life-cycles. We explore how both known and novel challenges map onto the different stages of development, highlighting interdisciplinary strategies for their resolution. (shrink)

Transplanting organs from emotionally related donors has become a fairly routine procedure in many countries. However, donors have to be chosen carefully in order to avoid not just medically, but also morally, questionable outcomes. This paper draws attention to vulnerabilities that may affect the voluntariness of the donor's decision. Suggestions are made as to how to approach the evaluation and selection of potential donors.

Living organ donation has developed into an important therapeutic option in transplantation medicine. However, there are some medico-ethical problems that come along with the increasing reliance on this organ source. One of these concerns is based on the observation that many more women than men function as living organ donors. Whereas discrimination and differential access have been extensively discussed in the context of cadaveric transplantation and other areas of health care, the issue of gender imbalance in living organ donation has (...) received less attention. This paper presents relevant data from the Eurotransplant and UNOS transplantation systems and discusses possible explanations for the documented gender discrepancies. The conclusion calls for are view of existing practice guidelines in order to secure effective protection of particularly vulnerable potential donors and an equitable donor-recipient-ratio in living organ donation.

In everyday conversations, professional codes, policy debates, and academic literature, the concept of respect is referred to frequently. Bioethical arguments in recent decades equate the idea of respect for persons with individuals who are capable of autonomous decision-making, with the focus being explicitly on ‘autonomy,’ ‘capacity,’ or ‘capability.’ In much of bioethics literature, respect for persons is replaced by respect for autonomy. Though the unconditional respect for persons and their autonomy (irrespective of actual decision-making capacity) is established in Kantian bioethics, (...) current argument and debates often revolve around a thin concept of autonomy, focusing on capacity and capability: persons are owed respect because they are ‘rational beings’ or with a focus on ‘agency’ and ‘decision-making abilities.’ However, these aspects alone are insufficient while engaging the concept of respect for persons, particularly in healthcare settings. This paper sets out to explore if the concept of respect for persons—as opposed to a thin concept of autonomy—could help us engage better in healthcare practices. We shall probe the practical value of the experiential aspect of respect—understood as the recognition of persons as respect-worthy through certain dispositions and deliberative acts—by reflecting on instances in clinical practice that tend to be dismissed as negligible or even unavoidable in a stressful environment such as a busy hospital. We shall argue that these instances are far from trivial but carry moral significance and express an unacceptable—disrespectful—attitude that can compromise the moral habitus in hospital settings. In our conclusion, we call for practicing recognition respect in the health professional–patient encounter by focussing on manners, attitudes, and behaviors. Furthermore, we call for continuous medical ethics education programs to address the moral significance of disrespectful behaviors and their manifestations in particular socio-cultural contexts.

Matters of hospital management do not figure prominently on the medical ethics agenda. However, management decisions that have to be taken in the area of hospital care are in fact riddled with ethical questions and do have significant impact on patients, staff members, and the community being served. In this decision making process evidence based medicine plays an increasingly important role as a tool for rationalising as well as rationing health care resources. In this article, ethical issues of hospital management (...) and the role of EBM will be explored, with particular reference to disease management programs, diagnosis related groups, and clinical pathways as recent developments in the German health care system.

Extended Reality (XR) systems, such as Virtual Reality (VR) and Augmented Reality (AR), provide a digital simulation either of a complete environment, or of particular objects within the real world. Today, XR is used in a wide variety of settings, including gaming, design, engineering, and the military. In addition, XR has been introduced into psychology, cognitive sciences and biomedicine for both basic research as well as diagnosing or treating neurological and psychiatric disorders. In the context of XR, the simulated ‘reality’ (...) can be controlled and people may safely learn to cope with their feelings and behavior. XR also enables to simulate environments that cannot easily be accessed or created otherwise. Therefore, Extended Reality systems are thought to be a promising tool in the resocialization of criminal offenders, more specifically for purposes of risk assessment and treatment of forensic patients. Employing XR in forensic settings raises ethical and legal intricacies which are not raised in case of most other healthcare applications. Whereas a variety of normative issues of XR have been discussed in the context of medicine and consumer usage, the debate on XR in forensic settings is, as yet, straggling. By discussing two general arguments in favor of employing XR in criminal justice, and two arguments calling for caution in this regard, the present paper aims to broaden the current ethical and legal debate on XR applications to their use in the resocialization of criminal offenders, mainly focusing on forensic patients.

Further discussion of the ongoing human cloning debate.In the late 1990s cloning was still the subject of passionate debate. While philosophers were crossing swords about the implications of the “Dolly technique” for the meaning of human identity, sweeping declarations were made by major international bodies such as the World Medical Association, UNESCO, and the World Health Organization that unanimously condemned human reproductive cloning as ethically unacceptable and/or contrary to human dignity. By now, the topic elicits a mere frown, sneer, sigh, (...) or yawn from most bioethicists, depending on their temperament or mood. The same may hold true for those delegates at the United Nations who sat through many sessions that included the ominous agenda item entitled “international convention against reproductive cloning of human beings”.Human cloning became an issue at the United Nations when the item was introduced at the request of France and Germany in 2001. The two countries limited their proposal to reproductive cloning. This move, although aiming quite reasonably at the formulation of a minimal consensus among member states, got at least Germany into some trouble at home, as critical voices from different parts of the political spectrum argued that Germany should rather pursue a comprehensive ban on human cloning for any purpose, which would be more in accordance with its own national ….

Risk and crisis communication (RCC) is a current ethical issue subject to controversy, mainly due to the tension between individual liberty (a core component of fairness) and effectiveness. In this paper we propose a consistent definition of the RCC process in public health emergencies (PHERCC), which comprises six key elements: evidence, initiator, channel, publics, message, and feedback. Based on these elements and on a detailed analysis of their role in PHERCC, we present an ethical framework to help design, govern and (...) evaluate PHERCC strategies. The framework aims to facilitate RCC, incorporating effectiveness, autonomy, and fairness. It comprises five operational ethical principles: openness, transparency, inclusivity, understandability, and privacy. The resulting matrix helps understanding the interplay between the PHERCC process and the principles of the framework. The paper includes suggestions and recommendations for the implementation of the PHERCC matrix. (shrink)

This paper presents scientists’ understanding of their roles in society and corresponding responsibilities. It discusses the researchers’ perspective against the background of the contemporary literature on scientific responsibility in the social sciences and philosophy and proposes a heuristic that improves the understanding of the complexity of scientific responsibility. The study is based on qualitative interviews with senior scientists. The presented results show what researchers themselves see as their responsibilities, how they assume them, and what challenges they perceive with respect to (...) their responsibilities. Regarding the latter, the interviewed researchers highlight those aspects of responsibility that go beyond the expertise of their professional role, and thus cannot be carried by scientists alone. For example, scientists alone cannot determine the general direction science takes, or the useful application of their research. The interviewed researchers describe those challenges as responsibilities that must be shared across different societal groups. In the theoretical literature, responsibility has been described as a relation between an actor (who), the action for which someone is responsible (what), and the normative framework against which someone is responsible (why). We will draw on this concept of “relational responsibility” to identify the various actors, normative frameworks, and actions relevant to scientific responsibility. This will serve as a heuristic tool to help identify the entanglement of responsibilities spread across several societal groups. (shrink)

Artificial intelligence (AI) systems are increasingly being used in healthcare, thanks to the high level of performance that these systems have proven to deliver. So far, clinical applications have focused on diagnosis and on prediction of outcomes. It is less clear in what way AI can or should support complex clinical decisions that crucially depend on patient preferences. In this paper, we focus on the ethical questions arising from the design, development and deployment of AI systems to support decision-making around (...) cardiopulmonary resuscitation and the determination of a patient’s Do Not Attempt to Resuscitate status (also known as code status). The COVID-19 pandemic has made us keenly aware of the difficulties physicians encounter when they have to act quickly in stressful situations without knowing what their patient would have wanted. We discuss the results of an interview study conducted with healthcare professionals in a university hospital aimed at understanding the status quo of resuscitation decision processes while exploring a potential role for AI systems in decision-making around code status. Our data suggest that (1) current practices are fraught with challenges such as insufficient knowledge regarding patient preferences, time pressure and personal bias guiding care considerations and (2) there is considerable openness among clinicians to consider the use of AI-based decision support. We suggest a model for how AI can contribute to improve decision-making around resuscitation and propose a set of ethically relevant preconditions—conceptual, methodological and procedural—that need to be considered in further development and implementation efforts.

This paper addresses the critiques based on trade-offs and normativity presented in response to our target article proposing the Public Health Emergency Risk and Crisis Communication (PHERCC) framework. These critiques highlight the ethical dilemmas in crisis communication, particularly the balance between promoting public autonomy through transparent information and the potential stigmatization of specific population groups, as illustrated by the discussion of the mpox outbreak among men who have sex with men. This critique underscores the inherent tension between communication effectiveness and (...) autonomy versus fairness and equity. In response, our paper reiterates the adaptability of the PHERCC framework, emphasizing its capacity to tailor messages to diverse audiences, thereby reducing potential stigmatization and misinformation. Through community engagement and feedback integration, the PHERCC framework aims to optimize the effectiveness of communication strategies while addressing ethical concerns. Furthermore, by involving affected communities in the communication strategy from the onset, the framework seeks to minimize ethical trade-offs and enhance the acceptance and effectiveness of public health messages.

Nanomedicine plays a prominent role among emerging technologies. The spectrum of potential applications is as broad as it is promising. It includes the use of nanoparticles and nanodevices for diagnostics, targeted drug delivery in the human body, the production of new therapeutic materials as well as nanorobots or nanoprotheses. Funding agencies are investing large sums in the development of this area, among them the European Commission, which has launched a large network for life-sciences related nanotechnology. At the same time government (...) agencies as well as the private sector are putting forward reports of working groups that have looked into the promises and risks of these developments. This paper will begin with an introduction to the central ethical themes as identified by selected reports from Europe and beyond. In a next step, it will analyse the most frequently invoked ethical concerns–risk assessment and management, the issues of human identity and enhancement, possible implications for civil liberties (e.g. nanodevices that might be used for covert surveillance), and concerns about equity and fair access. Although it seems that the main ethical issues are not unique to nanotechnologies, the conclusion will argue against shrugging them off as non-specific items that have been considered before in the context of other biomedical technologies, such as gene therapy or xenotransplantation. Rather, the paper will call on ethicists to help foster a rational, fair and participatory discourse on the different potential applications of nanotechnologies in medicine, which can form the basis for informed and responsible societal and political decisions.

This volume gives an overview on the currently debated ethical issues regarding advance directives from an international perspective. It focuses on a wider understanding of the known and widely accepted concept of patient self-determination for future situations. Although advance directives have been widely discussed since the 1980s, the ethical bases of advance directives still remain a matter of heated debates. The book aims to contribute to these controversial debates by integrating fundamental ethical issues on advance directives with practical matters of (...) their implementation. Cultural, national and professional differences in how advance directives are understood by health care professions and by patients, as well as in laws and regulations, are pinpointed. (shrink)

Large language models (LLMs) have now entered the realm of medical ethics. In a recent study, Balaset alexamined the performance of GPT-4, a commercially available LLM, assessing its performance in generating responses to diverse medical ethics cases. Their findings reveal that GPT-4 demonstrates an ability to identify and articulate complex medical ethical issues, although its proficiency in encoding the depth of real-world ethical dilemmas remains an avenue for improvement. Investigating the integration of LLMs into medical ethics decision-making appears to be (...) an interesting avenue of research. However, despite the promising trajectory of LLM technology in medicine, it is crucial to exercise caution and refrain from attributing their expertise to medical ethics. Our thesis follows an examination of the nature of expertise and the epistemic limitations that affect LLM technology. As a result, we propose two more fitting applications of LLMs in medical ethics: first, as tools for mining electronic health records or scientific literature, thereby supplementing evidence for resolving medical ethics cases, and second, as educational platforms to foster ethical reflection and critical thinking skills among students and residents. The integration of LLMs in medical ethics, while promising, requires careful consideration of their epistemic limitations. Consequently, a well-considered definition of their role in ethically sensitive decision-making is crucial. (shrink)

Das Buch enthält aktuelle Fallbesprechungen: Zukonkreten Fällen aus dem Feld der Bio- und Medizinethik wird eine kurze Analyse ethischer Aspekte dargestellt, an die sich juristische Kommentare anschließen. Diskutiert werden nicht-klinische Fälle aus Forschungsethik und Ethik in den Lebenswissenschaften sowie Fälle aus der klinischen Praxis in den Bereichen Chirurgie, Intensiv- und Notfallmedizin, genetisches Screening, Allgemeinmedizin, Neurologie, Psychiatrie und innere Medizin.

DieMedizinIntensivmedizin Intensivmedizin ist ein wichtiges Arbeitsfeld der biomedizinischen Ethik. In vielen Fällen werden existentielle Fragen des Menschseins berührt, um die Individuen und Gesellschaften immer wieder erneut ringen: Unter welchen Umständen erwarte oder erhoffe ich als Intensivpatient welche Art der Zuwendung? Welche Verpflichtung habe ich als Angehöriger dem Patienten gegenüber, wie kann ich meiner Rolle als Bezugsperson gerecht werden? Welche Verantwortung hat die Gemeinschaft bzw. der Staat gegenüber Schwerkranken und Sterbenden? Was ist ein guter Tod und wer darf darüber befinden? Namen (...) wie „Karen Quinlan“ oder „Nancy Cruzan“, zwei junge Frauen, die sich nach einem Unfall über Jahre hinweg in einem Zustand des apallischen Syndroms (‚Wachkoma‘) befanden, erinnern an die intensiven Debatten, die über die letzten Jahrzehnte zu diesen Fragen geführt wurden. Zudem ist die Intensivmedizin seit ihren Anfangstagen zur Zeit der Polioepidemien und der Entwicklung verschiedener Organersatztherapien (Dialyse, Beatmung) in der Mitte des letzten Jahrhunderts von Allokationsfragen begleitet: Welcher Patient soll die knappe Ressource erhalten und wer soll darüber anhand welcher Kriterien entscheiden dürfen? Die kritischen Diskussionen zum „God Committee“ von Seattle – einem Bürgerkomitee, das Anfang der 1960er Jahre über den Zugang von Patienten zur Dialyse befand – sowie um die Zuteilungskriterien für Organe Verstorbener zum Zwecke der Transplantation illustrieren, dass es sich hierbei im Kern nicht um medizinischtechnische, sondern um Gerechtigkeitsfragen sowie um Fragen der Abwägung individual- und sozialethischer Prinzipien handelt.

In our recent article ‘The Ethics of the Algorithmic Prediction of Goal of Care Preferences: From Theory to Practice’1, we aimed to ignite a critical discussion on why and how to design artificial intelligence (AI) systems assisting clinicians and next-of-kin by predicting goal of care preferences for incapacitated patients. Here, we would like to thank the commentators for their valuable responses to our work. We identified three core themes in their commentaries: (1) the risks of AI paternalism, (2) worries about (...) attacks to our humanity stemming from the use of AI and (3) the possibility of designing AI systems for more relevant use cases than the one we consider in our work. We shall focus on these themes, leaving aside some other interesting suggestions, given the limited space available for our response. Diaz Milian and Bhattacharyya discuss the risks of AI paternalism highlighting how the use of an AI to predict goal of care preferences may incentivise clinicians and surrogates to shift the burden of decision making to the machine.2 In particular, ‘[i]f the AI-generated response is given priority above the other agents’2 and the AI makes decisions autonomously, then ‘AI paternalism’ would emerge.2 Against this possibility, the authors suggest four safeguards to be implemented in the AI life-cycle.2 These are procedures that may improve the trustworthiness of the AI and human control over it.3 We agree that it is important ….

Kantian deontology is one of three classic moral theories, among virtue ethics and consequentialism. Issues in medical ethics are frequently addressed within a Kantian paradigm, at least – although not exclusively – in European medical ethics. At the same time, critical voices have pointed to deficits of Kantian moral philosophy which must be examined and discussed. It is argued that taking concrete situations and complex relationships into account is of paramount importance in medical ethics. Encounters between medical or nursing staff (...) and patients are rarely symmetrical relationships between autonomous and rational agents. Kantian ethics, the criticism reads, builds on the lofty ideal of such a relationship. In addition to the charge of an individualist and rationalist focus on autonomy, Kantian ethics has been accused of excluding those not actually in possession of these properties or of its rigorism. It is said to be focussed on laws and imperatives to an extent that it cannot appreciate the complex nuances of real conflicts. As a more detailed analysis will show, these charges are inadequate in at least some regards. This will be demonstrated by drawing on the Kantian notion of autonomy, the role of maxims and judgment and the conception of duties, as well as the role of emotions. Nevertheless the objections brought forward against Kantian moral theory can help determine, with greater precision, its strengths and shortcomings as an approach to current problems in medical ethics.

Psychotherapy is a well-established, efficacious, and fully accepted treatment for mental disorders and psychological problems. Psychotherapy is an interpersonal practice engaging patient values, interests, and personal meanings at every step. Thereby, psychotherapy abounds with moral issues. In psychotherapy ethics, numerous moral issues converge, including self-determination or autonomy, decision-making capacity and freedom of choice, coercion and constraint, medical paternalism, boundaries between health and illness, insight into illness and the need for therapy, dignity, under- and overtreatment, and much more. The Oxford Handbook (...) of Psychotherapy Ethics covers the whole range of ethical issues in the heterogenous field of psychotherapy, closing a commonly perceived gap between ethical sensitivity, technical language, and knowledge among psychotherapists. The primary audience is psychotherapists in clinical practice. Furthermore, the Oxford Handbook of Psychotherapy Ethics addresses the whole range of professionals providing mental health services beyond psychology and medicine including counselors, social workers, nurses, or ministers. The Oxford Handbook of Psychotherapy Ethics is not only intended for a clinical audience but also for a philosophical/ethical audience. The goal of the is to explicitly link the two disciplines by fostering a productive dialogue between them, enriching both the psychotherapeutic encounter and the ethical analysis and sensitivity within and outside the clinic.

The current humanitarian use of drones is focused on two applications: disaster mapping and medical supply delivery. In response to the growing interest in drone deployment in the aid sector, we sought to develop a resource to support value sensitivity in humanitarian drone activities. Following a bottom-up approach encompassing a comprehensive literature review, two empirical studies, a review of guidance documents, and consultations with experts, this work illuminates the nature and scope of ethical challenges encountered by humanitarian organizations embarking upon (...) innovation programmes. The Framework for the Ethics Assessment of Humanitarian Drones (FEAHD) identifies five values and five key questions related to ethical considerations along the decision chain of humanitarian drone activities. It fills a gap between high-level, principle-based guidance related to humanitarian innovation, and detailed operation-oriented checklists for projects involving the use of drones. In this way, the FEAHD contributes to support value sensitivity in the humanitarian use of drones. (shrink)

A patient’s decision-making capacity or competence is among the prerequisites for valid consent to medical treatment, and is regarded as the gatekeeping element in ensuring respect for patients’ self-determination. The issue is especially relevant in the case of vulnerable persons, such as patients who are cognitively or mentally impaired, and where medical decisions carry far-reaching consequences. As a grounding principle, DMC is a priori assumed, and challenged only when substantial doubts arise owing to observed or assumed deficiencies of the capacities (...) commonly considered relevant for competent decision making ; in this sense, the onus is on...

This article tries to present a broad view on the values and ethicalissues that are at stake in efforts to rationalize health policy on thebasis of economic evaluations (like cost-effectiveness analysis) andrandomly controlled clinical trials. Though such a rationalization isgenerally seen as an objective and `value free' process, moral valuesoften play a hidden role, not only in the production of `evidence', butalso in the way this evidence is used in policy making. For example, thedefinition of effectiveness of medical treatment or (...) health care serviceis heavily dependent on dominant individual or social views about thegoals of the particular treatment or service. There is also a concernthat a reliance on EBM in health policy will occur at the expense ofwidely shared social values like equity and solidarity. Moreover, thereis a concern that when economic considerations and rational proceduresbecome more influential, various `outside' groups third parties likeinsurance companies and policy makers will get a stronger influence onmedical practice which may lead to a change in the patient-providerrelationship. The authors conclude that social values and patientpreference should be explicitly addressed when health policy making isbased on economic and other scientific evidence. (shrink)

BackgroundThe need for an ethical debate about the use of coercion in intensive care units (ICU) may not be as obvious as in other areas of medicine, such as psychiatry. Coercive measures are often necessary to treat critically ill patients in the ICU. It is nevertheless important to keep these measures to a minimum in order to respect the dignity of patients and the cohesion of the clinical team. A deeper understanding of what patients and their relatives perceive during their (...) ICU stay will shed different light on intensive care management. Patients' experiences of loss of control, dependency and abandonment may lead to a new approach towards a broader approach to the concept of coercion in intensive care. The aim of our research is to explore the experiences of patients and relatives in the ICU and to determine when it might be possible to reduce feelings and memories of coercion.MethodsWe conducted and analysed 29 semi-structured interviews with patients and relatives who had been in the ICU a few months previously. Following a coding and categorisation process in MAXQDA™, a rigorous qualitative methodology was used to identify themes relevant to our research.ResultsFive main themes emerged: memory issues; interviewees’ experiences of restricting measures and coercive treatment; patients’ negative perception of situational and relational dependency with the risk of informal coercion; patients’ perceptions of good care in a context of perceived dependency; progression from perception of coercion and dependency to respect for the person. All patients were grateful to have survived. However, coercion in the form of restraint, restriction of movement, and coercive treatment in the ICU was also acknowledged by patients and relatives. These included elements of informal coercion beyond restraints, such as a perceived negative sense of dependence, surrender, and asymmetrical interaction between the patient and health providers.ConclusionsTo capture the full range of patients' experiences of coercion, it is necessary to expand the concept of coercion to include less obvious forms of informal coercion that may occur in dependency situations. This will help identify solutions to avoid or reduce negative recollections that may persist long after discharge and negatively affect the patients' quality of life. (shrink)

How health care providers are paid affects how medicine is practiced. It is thus important to assess provider payment models not only from the economic perspective but also from the ethical perspective. China recently started to reform the provider payment model in the health care system from fee-for-service to case-based payment. This paper aims to examine this transition from an ethical perspective. We collected empirical studies on the impact of case-based payment in the Chinese health care system and applied a (...) systematic ethical matrix that integrates clinical ethics and public health ethics to analyze the empirical findings. We identified eleven prominent ethical issues related to case-based payment. Some ethical problems of case-based payment in China are comparable to ethical problems of managed care and diagnosis related groups in high-income countries. However, in this paper we discuss in greater detail four specific ethical issues in the Chinese context: professionalism, the patient-physician relationship, access to care and patient autonomy. Based on the analysis, we cautiously infer that case-based payment is currently more ethically acceptable than fee-for-service in the context of China, mainly because it seems to lower financial barriers to access care. Nonetheless, it will be difficult to justify the implementation of case-based payment if no additional measures are taken to monitor and minimize its existing negative ethical implications. (shrink)
