Bioethics

Bioethics

The study of moral principles and values that guide decision-making in biology, medicine, research and biotechnology, particularly when scientific advances impact human wellbeing, rights and society.

Importance of bioethics

It ensures scientific progress is responsible, fair and safe, balancing innovation with human rights, societal values and potential risks.

Moral considerations in bioethics

Factors that influence what is considered right or wrong, including maximizing patient outcomes, following professional duties, ensuring fairness and equality, considering policy consequences, and respecting patient opinions.

Moral dilemma in healthcare

Deciding whether to respect a minor’s medical wishes if they conflict with parental decisions—balancing autonomy vs duty of care.

Key bioethical issues

Includes euthanasia & assisted suicide, genetic testing & screening, IVF & reproductive technologies, resource allocation, clinical trials, consent & vulnerability, mental health care, and animal testing.

Ethical issue in genetic testing

Potential for psychological harm, discrimination, and privacy breaches, especially if results predict future disease.

Ethical concern in resource allocation

Limited resources require decisions about who receives treatment, raising issues of justice and fairness.

Consequence-based approach

Focuses on outcomes—actions are ethical if they maximize overall benefit and minimize harm.

Duty-based approach

Focuses on rules and obligations—actions are ethical if they follow moral rules, regardless of outcomes.

Virtue-based approach

Focuses on the moral character of the individual—ethical decisions come from acting as a virtuous person.

Comparison of ethical approaches

Consequence-based seeks the best outcome, duty-based follows rules, virtue-based emphasizes being a good person.

Autonomy

The right of individuals to make informed decisions about their own healthcare without coercion.

Non-maleficence

The obligation to avoid causing harm, ensuring risks are minimized and justified.

Beneficence

The duty to act in the best interest of the patient, promoting wellbeing.

Justice in bioethics

Fair and equitable distribution of resources and treatment across society.

Integrity in bioethics

Conducting research and practice with honesty, transparency, and accountability, ensuring informed decisions.

Application of ethical principles to end-of-life care

Autonomy: patient choice; Beneficence: reduce suffering; Non-maleficence: avoid unnecessary harm; Justice: fair access to care.

Application of ethical approaches to euthanasia

Consequence: reduces suffering; Duty: may violate 'do not kill'; Virtue: depends on compassion.

Social factors in bioethics

Influences from society’s beliefs, values and attitudes, including equality, public health, and cultural views.

Example of a social factor

Attitudes toward abortion or euthanasia vary between societies.

Economic factors in bioethics

Financial considerations affecting decisions, such as cost of treatments and resource availability.

Socioeconomic factor

The interaction between social and economic status, affecting access to healthcare and decision-making.

Legal factors in bioethics

Laws and regulations that determine what is permitted or prohibited in healthcare and research.

Example of a legal factor

Laws regulating clinical trials or embryo research ensure ethical compliance.

Political factors in bioethics

Government decisions that influence healthcare systems, funding, and policy.

Example of a political factor

Government funding decisions affecting hospital resources or vaccine programs.

Why bioethical decisions differ between countries

They are influenced by social values, economic resources, legal systems, and political priorities.

Key challenge in bioethics

Balancing competing principles (e.g., autonomy vs beneficence) when no solution satisfies all stakeholders.

Importance of informed consent

It ensures autonomy and integrity, allowing individuals to make decisions with full knowledge of risks and benefits.

Ultimate goal of bioethics

To ensure biological advancements are ethical, equitable, and beneficial to individuals and society.
