The four pillars & a method for any ethics station

Before the debates, learn the framework behind almost every ethics question — and a simple method to structure an answer to a scenario you have never seen.

The four pillars

Four ideas sit behind nearly every ethical question in medicine. Most of the time they agree; the interesting questions happen when they are in conflict.

AutonomyThe patient’s right to make their own decisions.
BeneficenceActing in the patient’s best interests.
Non-maleficenceFirst, do no harm.
JusticeFairness, and using limited resources well.

A method for any station

This is the toolkit you’ll use on every debate that follows in this guide — especially assisted dying, next.

Ethics & Society

Assisted dying

One of the biggest ethical debates in UK medicine right now — and a favourite interview question, because there is no “right” answer.

What you need to know

Parliament has debated legalising assisted dying for terminally ill adults (the Terminally Ill Adults (End of Life) Bill). Broadly, it would let some dying patients — expected to die within a set time and with the mental capacity to decide — ask for help to end their life, with safeguards such as assessment by two doctors and independent oversight.

It is different from euthanasia, where a doctor actively administers the medication. “Assisted dying” usually means the patient takes it themselves. Health is devolved, so the law can differ across England, Scotland, Wales and Northern Ireland.

The debate

Arguments in favour

  • Respects patient autonomy over their own death
  • Can relieve unbearable suffering palliative care cannot always reach (beneficence)
  • Strict safeguards — capacity checks, time limits, oversight — can reduce the risks

Arguments against

  • Risk of coercion of vulnerable or disabled people (non-maleficence, justice)
  • A possible “slippery slope” to wider eligibility over time
  • Could affect trust in doctors and divert focus from palliative care
In the interview

They want balanced reasoning, not your verdict. Name the conflict (autonomy vs protecting the vulnerable), give points on both sides, and conclude humbly — mentioning the role of safeguards.

  • “Should assisted dying be legal in the UK?”
  • “How would you weigh patient autonomy against the risk of coercion?”

Ethics & Society

Health inequalities & mental health

Where you’re born can change your life expectancy by a decade — and interviewers want to know you understand why.

What you need to know

Health outcomes vary sharply by income, region and ethnicity. These differences are driven largely by the social determinants of health — housing, income, education, work and environment — not just by healthcare. The Marmot reviews showed how wide the gap is, and that it has grown.

At the same time, demand for mental health care has risen, especially among young people, and services are stretched. Parity of esteem — the principle that mental health should be valued equally to physical health — is official policy but not yet the reality.

Two ways of thinking about it

What a clinician can do

  • Spot and refer early; practise culturally aware care
  • “Social prescribing” — linking patients to non-medical support
  • Advocate for patients and for prevention

Why it’s hard

  • Most causes lie upstream, outside the clinic
  • Prevention saves money slowly; pressures are immediate
  • The patients in most need often find care hardest to access
In the interview

Show you know medicine alone can’t fix this — but that doctors still have a real role, and that public health and policy matter.

  • “What can a doctor do about causes of ill health that lie outside the clinic?”
  • “Why might two patients with the same illness have very different outcomes?”

Policy, Funding & Structure

The 10 Year Health Plan

England’s big plan for the future of the NHS — a neat way to show you understand where the service is heading.

What you need to know

The plan is built around three shifts:

The debate

Why it could work

  • Care closer to home can improve access and catch problems earlier
  • Prevention is cheaper and kinder than late treatment
  • Digital tools can free up clinician time

What could stop it

  • It needs workforce, funding and time the NHS is short of
  • Prevention pays off slowly while pressures are immediate
  • Going digital risks excluding some patients (the digital divide)
In the interview

Don’t just list the shifts — pick one, say why it matters most, and name a risk of getting it wrong.

  • “Which of the three shifts would help patients most?”
  • “Why is prevention so hard for the NHS to prioritise?”

Policy, Funding & Structure

Funding, structure & social care

How the NHS is paid for and organised — the backdrop to almost every other topic.

What you need to know

The NHS is funded mainly through general taxation and is free at the point of use. To cut duplication, NHS England is being abolished and merged into the Department of Health and Social Care.

Social care — help with everyday living, like washing and dressing — is separate from the NHS and largely means-tested. It is chronically underfunded, and gaps there pile pressure back onto hospitals: patients who are medically fit can’t be discharged safely, so beds stay full.

The debate

The case for reform

  • Merging bodies could streamline decisions and save money
  • Tax funding is fair — care by need, not ability to pay

The worries

  • Restructuring can distract and cost money during transition
  • Social care reform is repeatedly promised and rarely delivered
  • A tax-funded system is squeezed as demand rises faster than budgets
In the interview

The strongest point to make is how tightly the NHS and social care are linked — you can’t fix one while ignoring the other.

  • “Does restructuring the NHS improve care, or distract from it?”
  • “How are the NHS and social care connected?”

Workforce & Roles

Resident doctors, pay & training

Doctors in training have been striking over pay — a live question about fairness, safety and the future workforce.

What you need to know

“Resident doctor” is the newer term for a doctor in training (formerly “junior doctor”). Disputes over pay, after years of real-terms decline, led to industrial action. Separately, competition for specialty training posts is intense, and retention is a problem — trained doctors leave the NHS or move abroad.

The debate

The case for action

  • Fair pay supports morale and keeps doctors in the NHS
  • Retention protects patient safety in the long run
  • Workers have a right to withdraw their labour

The concerns

  • Strikes disrupt care and can put patients at risk short-term
  • Large pay rises strain an already tight budget
  • Fairness to patients left waiting
In the interview

This tests balanced reasoning and professionalism, not your politics. Weigh workers’ rights against patient safety, and mention that emergency cover is maintained during strikes.

  • “Is it ethical for doctors to go on strike?”
  • “Why does keeping hold of trained doctors matter so much?”

Workforce & Roles

Physician associates & scope of practice

A newer role that has become one of the most contested topics in the NHS — great for discussing patient safety and teamwork.

What you need to know

Physician associates (PAs) and anaesthesia associates (AAs) support doctors. They typically train for around two years after a science degree — they are not doctors. After concerns about role confusion and some high-profile incidents, the Leng review examined their safety, scope and supervision. They are now regulated by the GMC, which some argue helpfully raises standards and others say blurs the line with doctors.

The debate

The case for PAs

  • Add capacity and free doctors for complex work
  • Support team-based care and continuity

The concerns

  • Risk to safety if scope and supervision are unclear
  • Patients may not realise they aren’t seeing a doctor
  • Can reduce training opportunities for junior doctors
In the interview

Be balanced and not dismissive of PAs. The key themes are transparency, clear scope of practice, supervision and good teamwork.

  • “How should the NHS make sure patients know who is treating them?”
  • “What makes a role like this safe or unsafe?”

Access & Prevention

Waiting lists & urgent care

The issue patients feel most — and a clear example of how the whole system is connected.

What you need to know

Elective (planned) waiting lists grew sharply after the pandemic, A&E departments are often crowded, and delayed discharge — patients who are medically fit but can’t safely leave, often because social care isn’t available — keeps beds full.

These are linked: no social care means blocked beds, which means A&E backs up, which means ambulances are delayed. A problem in one place shows up as a delay somewhere else.

The trade-offs

Ways to tackle it

  • Fund more capacity (staff, beds, theatres)
  • Invest in social care so patients can be discharged
  • Prevention and community care to reduce demand

Why it’s tricky

  • How to prioritise: clinical need vs how long someone has waited
  • Targets can distort care — chasing the metric, not the patient
  • Money spent in one place is money not spent elsewhere
In the interview

Show you understand flow through the system — the best answers explain how the parts connect.

  • “Why do pressures in social care show up as delays in hospitals?”
  • “How would you decide who to treat first on a waiting list?”

Access & Prevention

GP access & neighbourhood health

Primary care is the NHS front door — and where a lot of current reform is aimed.

What you need to know

Getting a GP appointment and seeing the same clinician each time (continuity of care) are common frustrations. Reform pushes neighbourhood health — multidisciplinary teams of GPs, nurses, pharmacists, physios and social prescribers delivering more care closer to home. Continuity improves outcomes, but is harder to maintain when access is shared across a big team.

The debate

What patients gain

  • Faster access and care closer to home
  • The right professional for the problem (not always a GP)
  • More focus on prevention

What they might lose

  • Continuity — a trusted clinician who knows them
  • Online or phone triage can exclude some patients
  • It all depends on having enough staff
In the interview

A thoughtful answer weighs convenience and access against the real value of continuity.

  • “What do patients gain and lose when care moves closer to home?”
  • “Why does seeing the same GP actually matter?”

Access & Prevention

Obesity, weight-loss drugs & public health

New weight-loss drugs have made obesity policy a hot topic — mixing science, money and personal responsibility.

What you need to know

Obesity raises the risk of type 2 diabetes, heart disease and some cancers. New GLP-1 medicines (such as semaglutide — Wegovy and Ozempic) cause significant weight loss and are in huge demand, but they are expensive and may need to be taken long-term. Alongside them sit public health measures: the sugar levy, junk-food advertising rules and smoking policy.

The debate

Points in favour of funding

  • Treating obesity prevents costly disease later (beneficence)
  • Obesity has strong biological and environmental drivers, not just “willpower”

Points against

  • Cost: funding for all who’d benefit is enormous (justice)
  • Drugs may need to be lifelong; is that sustainable?
  • Risk of medicalising obesity instead of fixing the causes
In the interview

This is really a resource-allocation question. Weigh the good the drugs do against their cost and fairness, and bring in prevention versus treatment.

  • “Should the NHS fund weight-loss drugs for everyone who could benefit?”
  • “Whose responsibility is obesity — the individual’s or the state’s?”

Science & Technology

AI & digital health

The fastest-moving topic in medicine — and a rich one for ethics.

What you need to know

AI is already helping with diagnosis (for example, reading scans), triage and admin (ambient voice tools that write up notes), while the NHS App widens digital access. The promise is speed, consistency and earlier detection. The questions are about accuracy, bias, consent, data privacy and — crucially — accountability: who is responsible when AI gets it wrong?

The debate

The promise

  • Fast, consistent, available around the clock
  • Frees clinicians to spend time with patients
  • Could widen access and catch disease earlier

The risks

  • Bias if trained on unrepresentative data (justice)
  • Over-reliance and loss of clinical skill
  • Privacy, consent, and the gap in accountability
In the interview

The strongest line: AI is a tool that supports clinicians, not a replacement — the doctor stays accountable, and bias and consent must be managed.

  • “Would you trust an AI second opinion — and who is accountable if it’s wrong?”
  • “Could AI make health inequalities better or worse?”

Science & Technology

Genomics & gene editing

We can now read a person’s whole genetic code in a day — and even rewrite parts of it. Huge promise, and some of the hardest ethics in medicine.

What you need to know

Your genome is your complete set of genes. Reading it (sequencing) has become fast and cheap — Genomics England ran the 100,000 Genomes Project. CRISPR is a tool that edits DNA like a molecular “find and replace”.

The key distinction to grasp: somatic editing changes a patient’s own cells — it helps them and is not inherited (like Casgevy, the approved sickle cell therapy). Germline editing changes an embryo, egg or sperm, so the change is in every cell and passed to all future generations — as in the condemned He Jiankui “edited babies” case.

The debate

The promise

  • Could cure devastating genetic diseases, not just manage them
  • Personalised treatment with fewer side effects
  • Prevention — acting before illness develops

The concerns

  • Germline edits are permanent and heritable — future people can’t consent
  • The slide from treatment to enhancement (“designer babies”)
  • Cost and access could widen inequality; genetic data privacy
In the interview

Lead with the somatic vs germline distinction — it’s the key that unlocks the whole debate. Then weigh both sides and stay comfortable with the grey areas.

  • “Should we edit the genes of embryos to prevent disease?”
  • “Where is the line between treating disease and enhancement?”
