Medical Ethics (Leaving Cert Religious Education): Revision Notes
Medical Ethics
What is medical ethics?
Medical ethics is the branch of ethics that deals with moral principles and values in medical practice and healthcare. It provides a framework for healthcare professionals to make difficult decisions when treating patients and conducting medical research. Medical ethics examines what is right and wrong in healthcare situations, helping doctors, nurses, and other medical professionals navigate complex moral dilemmas.
The field addresses fundamental questions about life, death, suffering, and human dignity. It considers how we should treat patients, what constitutes good medical practice, and how to balance competing interests and values in healthcare settings.
Core principles of medical ethics
Medical ethics is built on four fundamental principles that guide decision-making in healthcare settings. These principles work together to provide comprehensive ethical guidance for medical professionals.
The Four Core Principles of Medical Ethics:
Autonomy - Respecting patients' right to make their own informed decisions about their medical care. This means providing patients with accurate information and allowing them to choose their treatment path, even if healthcare professionals disagree with their choice.
Beneficence - The duty to do good and act in the patient's best interests. Healthcare professionals should aim to provide treatments and care that will benefit the patient and improve their wellbeing.
Non-maleficence - The obligation to "do no harm." This principle requires healthcare professionals to avoid causing unnecessary harm or suffering to patients, even when trying to help them.
Justice - The fair distribution of healthcare resources and equal treatment of patients regardless of their background, social status, or ability to pay. This principle addresses questions about who should receive scarce medical resources.
How moral theories influence medical decisions
Different moral philosophies provide distinct approaches to ethical decision-making in healthcare contexts. Understanding these theoretical frameworks helps healthcare professionals approach complex situations with greater clarity and consistency.
Consequentialist approach
Consequentialism judges the rightness of actions based on their outcomes or consequences. In medical ethics, this approach focuses on achieving the best possible results for patients and society.
A consequentialist might support:
- Allocating limited medical resources to treatments that save the most lives
- Conducting medical research that could benefit many future patients
- Making treatment decisions based on statistical outcomes and success rates
Worked Example: Consequentialist Decision-Making
A hospital has one ventilator available and two patients who need it. Patient A is 30 years old with a 80% chance of recovery, while Patient B is 75 years old with a 40% chance of recovery.
A consequentialist approach would allocate the ventilator to Patient A because this choice produces the best overall outcome - higher probability of saving a life and potentially more years of life saved.
Deontological approach
Deontology emphasises duty and moral rules rather than consequences. This approach focuses on whether actions are inherently right or wrong, regardless of their outcomes.
A deontologist might prioritise:
- Always telling patients the truth, even when it might cause distress
- Respecting patient autonomy as an absolute moral duty
- Following professional codes of conduct and medical guidelines strictly
Worked Example: Deontological Decision-Making
A patient asks their doctor about their terminal diagnosis. The family has requested that the patient not be told, believing it will cause unnecessary suffering.
A deontological healthcare professional would tell the patient the truth because honesty is a fundamental moral duty, regardless of the potential emotional consequences.
Virtue ethics approach
Virtue ethics focuses on moral character rather than specific actions or outcomes. It asks what kind of person one should be rather than what one should do.
A virtue ethics approach emphasises:
- Developing compassion, integrity, and wisdom as a healthcare professional
- Considering how decisions reflect on one's character as a healer
- Building trust and maintaining professional relationships
A healthcare professional following virtue ethics might focus on being honest, caring, and professionally competent in all interactions with patients, viewing these character traits as essential to good medical practice.
Major medical ethical dilemmas
Several key areas present ongoing ethical challenges in healthcare, where different moral theories often provide conflicting guidance.
End-of-life care
Decisions about when to continue or withdraw life-sustaining treatment raise complex questions about the value of life, quality of life, and patient autonomy. Different moral theories provide varying guidance on issues like euthanasia, assisted dying, and palliative care.
Resource allocation
With limited healthcare resources, difficult decisions must be made about who receives treatment, organ transplants, or expensive medications. Moral theories offer different approaches to these distribution questions.
Resource allocation becomes particularly challenging during health crises, such as pandemics, when demand for medical resources far exceeds supply and healthcare systems must make rapid decisions about patient care priorities.
Medical research and experimentation
The development of new treatments requires research involving human subjects, creating tensions between advancing medical knowledge and protecting individual participants from harm.
Informed consent and patient autonomy
Balancing respect for patient choice with professional medical judgement becomes challenging when patients make decisions that healthcare professionals believe are harmful.
Genetic testing and enhancement
Advances in genetics raise questions about testing for diseases, genetic modification, and what constitutes normal human variation versus medical conditions requiring treatment.
Practical applications
When facing medical ethical dilemmas, healthcare professionals can apply a systematic approach using different moral frameworks to reach well-reasoned decisions.
Worked Example: Ethical Decision-Making Process
Scenario: A patient refuses a blood transfusion due to religious beliefs, but the transfusion is necessary to save their life.
Step 1: Identify the ethical issue - Conflict between respecting patient autonomy and the duty to preserve life.
Step 2: Consider stakeholders - Patient, family, healthcare team, and religious community.
Step 3: Apply moral theories -
- Consequentialist: Focus on saving the patient's life
- Deontological: Respect the patient's autonomous decision
- Virtue ethics: Act with compassion while maintaining professional integrity
Step 4: Evaluate options - Respect refusal, seek alternative treatments, or consult ethics committee.
Step 5: Make a reasoned decision - Most ethical frameworks would support respecting the patient's informed refusal while exploring all alternative treatment options.
Understanding how moral theories influence medical decisions helps healthcare professionals make more thoughtful, ethically justified choices in complex situations.
Key Points to Remember:
- Medical ethics applies moral principles to healthcare decisions and medical practice
- Four core principles guide medical ethics: autonomy, beneficence, non-maleficence, and justice
- Consequentialism focuses on outcomes and results when making medical decisions
- Deontology emphasises moral duties and rules regardless of consequences
- Virtue ethics considers the character and integrity of the healthcare professional making decisions
- A systematic approach to ethical decision-making helps healthcare professionals navigate complex moral dilemmas
