The difficulty of explaining the outputs of artificial intelligence (AI) models and what has led to them is a notorious ethical problem wherever these technologies are applied, including in the medical domain, and one that has no obvious solution. This paper examines the proposal, made by Luciano Floridi and colleagues, to include a new ‘principle of explicability’ alongside the traditional four principles of bioethics that make up the theory of ‘principlism’. It specifically responds to a recent set of criticisms that (...) challenge the supposed need for such a principle to perform an enabling role in relation to the traditional four principles and therefore suggest that these four are sufficient without the addition of explicability. The paper challenges the critics’ premise that explicability cannot be an ethical principle like the classic four because it is explicitly subordinate to them. It argues instead that principlism in its original formulation locates the justification for ethical principles in a midlevel position such that they mediate between the most general moral norms and the contextual requirements of medicine. This conception of an ethical principle then provides a mold for an approach to explicability on which it functions as an enabling principle that unifies technical/epistemic demands on AI and the requirements of high-level ethical theories. The paper finishes by anticipating an objection that decision-making by clinicians and AI fall equally, but implausibly, under the principle of explicability’s scope, which it rejects on the grounds that human decisions, unlike AI’s, can be explained by their social environments.

Communicating an unfavourable prognosis while maintaining patient hope represents a critical challenge for healthcare professionals. Duty requires respect for the right to patient autonomy while at the same time not doing harm by causing hopelessness and demoralisation. In some cases, the need for therapeutic privilege is discussed. The primary objectives of this study were to explore HPs’ perceptions of hope in the prognosis communication and investigate how they interpret and operationalise key ethical principles. Sixteen qualitative semistructured interviews with HPs from (...) different positions and experience, including doctors and nurses in four different departments, were conducted in the Ticino Cantonal Hospital, Switzerland. The interviews were recorded, transcribed verbatim and analysed using thematic analysis. HPs defined prognosis and patient hope as interdependent concepts related to future perspectives for subjective quality of life. Two main factors allow HPs to maximise the benefits and minimise the harm of their communication: respecting the patient’s timing and sharing the patient’s wishes. Time is required to reframe needs and expectations. Furthermore, communication needs to be shared by HPs, patients and their relatives to build common awareness and promote a person-centred approach to prognosis. In this process, interprofessional collaboration is key: doctors and nurses are complementary and can together guarantee that patients and relatives receive information in the most appropriate form when they need it. Organisational aspects and the HPs’ emotional difficulties, particularly in coping with their own despair, are barriers to effective communication that need further investigation. (shrink)

With the growing application of machine learning models in medicine, principlist bioethics has been put forward as needing revision. This paper reflects on the dominant trope in AI ethics to include a new ‘principle of explicability’ alongside the traditional four principles of bioethics that make up the theory of principlism. It specifically suggests that these four principles are sufficient and challenges the relevance of explicability as a separate ethical principle by emphasizing the coherentist affinity of principlism. We argue that, through (...) specification, the properties of explicability are already covered by the four bioethical principles. The paper finishes by anticipating an objection that coherent principles could not facilitate technology induced change and are not well-suited to tackle moral differences. (shrink)

Lukas J. Meier et al. offer the promise of a pathway for resolving clinical bioethical problems using an artificial intelligence interface. The ultimate goal, we assume, is...

Background: The four principles of Beauchamp and Childress - autonomy, non-maleficence, beneficence and justice - havebeen extremely influential in the field of medical ethics, and are fundamental for understanding the currentapproach to ethical assessment in health care. This study tests whether these principles can be quantitativelymeasured on an individual level, and then subsequently if they are used in the decision making process whenindividuals are faced with ethical dilemmas. Methods: The Analytic Hierarchy Process was used as a tool for the measurement (...) of the principles. Four scenarios, whichinvolved conflicts between the medical ethical principles, were presented to participants and they madejudgments about the ethicality of the action in the scenario, and their intentions to act in the same manner if theywere in the situation. Results: Individual preferences for these medical ethical principles can be measured using the Analytic HierarchyProcess. This technique provides a useful tool in which to highlight individual medical ethical values. Onaverage individuals have a significant preference for non-maleficence over the other principles, however, andperhaps counter-intuitively, this preference does not seem to relate to applied ethical judgements in specificethical dilemmas. Conclusions: People state they value these medical ethical principles but they do not actually seem to use them directly in thedecision making process. The reasons for this are explained through the lack of a behavioural model to accountfor the relevant situational factors not captured by the principles. The limitations of the principles in predictingethical decision making are discussed. (shrink)

Deprescribing is the term used to describe the process of withdrawal of an inappropriate medication supervised by a clinician. This article presents a discussion of how the Four Principles of biomedical ethics that may guide medical practitioners’ prescribing practices apply to deprescribing medications in older adults. The view of deprescribing as an act creates stronger moral duties than if viewed as an omission. This may explain the fear of negative outcomes which has been reported by prescribers as a barrier to (...) deprescribing. Respecting the autonomy of older adults is complex as they may not wish to be active in the decision-making process; they may also have reduced cognitive function and family members may therefore have to step in as surrogate decision-makers. Informed consent is intended as a process of information giving and reflection, where consent can be withdrawn at any time. However, people are rarely updated on the altered risks and benefits of their long-term medications as they age. Cessation of inappropriate medication use has a large financial benefit to the individual and the community. However, the principle of justice also dictates equal rights to treatment regardless of age. (shrink)

Principlism appears to be the prevailing applied ethical framework in bioethics. Despite the view’s various strengths, critics point out that since the principles are ad hoc, conflicts indubitably emerge leading to inconsistency. There is debate around whether principlism can provide definitive action-guiding moral prescriptions or only help structure intelligent analyses and justifications of moral choices. In this paper, I contend that applying concepts of moral symmetry and moral asymmetry allows us to modify one of principlism’s principles—the principle of beneficence—into what (...) I will call the principle of compassion. I argue that the principle of compassion can function as an arbitrating or primary principle within the principlist framework. The result is a view we might call compassionate principlism. Arguably, compassionate principlism leads to fewer inconsistencies and provides more acceptable action-guiding moral prescriptions than traditional principlism. (shrink)
