Ethical Dimensions and Professional Ethical Guidance on End-of-Life Decisions

This chapter examines the principal ethical dimensions of end-of-life decisions and the manner in which biomedical principles guide difficult clinical choices. It begins by outlining the governing ethical principles of sanctity of life, beneficence, non-maleficence, autonomy and justice and then analyses the dilemmas that arise when these principles come into tension in practice. Particular attention is given to withholding and withdrawal of life-sustaining treatment, palliative and terminal sedation, medical futility, distributive justice and the distinction between “killing” and “letting die”. The chapter shows that although respect for autonomy is central to contemporary bioethics, it is not absolute and must be assessed in relation to the patient’s best interests, vulnerability, quality of life and the doctor’s professional obligations. It further contends that end-of-life decisions should not be reduced to purely clinical judgement but should instead be approached through structured shared decision-making that accommodates communication, capacity assessment, family involvement and the patient’s values and beliefs. The chapter also examines Malaysian professional ethical codes, clinical guidelines and palliative care standards insofar as they reflect and operationalise these ethical principles in local end-of-life care. In the Malaysian context, these instruments are significant in demonstrating that ethical end-of-life care must remain responsive to religion, culture, family involvement and local clinical realities.
