Summary of Organ Transplant Dilemmas in the UK for Medical Interviews

1. There are around 8,000 people in the UK actively waiting for an organ transplant – the highest number on record (as of March 2025) – ranging from hearts to corneas, with thousands more temporarily suspended from the list.
2. Scotland, England, Wales, and Northern Ireland all currently operate on an opt-out organ donation system, though this is controversial
3. People are waitlisted for organs based on various metrics, including factors that may affect their long-term health (eg continuing to drink while waiting for a liver transplant will almost always lead a patient to be deprioritised)
4. Other key ethical dilemmas include whether or not we should allow people to sell their organs, and what other restrictions should be placed on transplant donors and recipients

Organ Donation Ethical Issues: Key Ethical and Social Dilemmas in the UK

How do organ transplants work in the UK?

When someone dies, some of their organs may be viable to be harvested. This depends on factors such as the biochemical, morphological, and functional viability of the organs. Many donors will have some organs that are viable for transplant and some that are not.

Organs are then viable for different amounts of time depending on what they are - for instance, a heart is viable for 4-6 hours whilst a kidney is viable for 24-36. During this time, they are matched to a prospective recipient on a national waiting list. This is also influenced by factors such as proximity and the capacity to actually carry out the procedure in time, as well as whether the patient is a match for the organ.

After the surgery, there is generally a long recovery period. This is because of various factors. Organ transplant surgeries tend to be long, with the potential for many complications. Additionally, after their surgery, a patient must take immunosuppressant medication to reduce the risk of organ rejection. However, this increases the risk of severe and possibly fatal response to infection.

Even once a patient has received a transplanted organ, there is still a high risk of premature death.

Should we have an opt-in or opt-out organ donation system in the UK?

What is Max and Keira's Law (deemed consent)?

England's opt-out system is widely known as Max and Keira's Law, named after Keira Ball, whose organs were donated after a fatal car accident, and Max Johnson, the boy who received her heart. Under this law, adults are treated as having agreed to donate their organs after death unless they have recorded a decision to opt out or fall into an excluded group. This default is sometimes called 'deemed consent'.

Opt-out now applies across all four UK nations: Wales adopted it first in December 2015, followed by England (Max and Keira’s Law) in May 2020, Scotland in March 2021 and Northern Ireland in June 2023. Even under deemed consent, families are still consulted, and donation will not usually go ahead against their strong objection.

An opt-in organ donation system is one where, if a person has not declared a preference before their death, it is assumed that they do not want to be an organ donor. They have to opt-in to avoid the default.

An opt-out system is the opposite - if the deceased has not registered a preference, their organs are still donated. They have to opt out of this system. Their next of kin, however, can generally opt-out on their behalf after their death.

The UK currently operates on an opt-out system. Arguments in favour of this include:

• Numbers: More organs would be donated, helping to address the ongoing shortage. Hundreds of people still die each year in the UK while waiting for a transplant, and the active waiting list reached a record high of around 8,000 in 2025.
• Prioritisation: When considering whether to prioritise those waiting for organs or deceased people who have not expressed a preference, it is possible to argue that we should prioritise those who have a chance to live for longer.
• Normalisation: An opt-out system would make organ donation seem more normal, encouraging more people to donate upon their death and choose not to opt-out.

Arguments in favour of an opt-in system include:

• Autonomy: It is possible that some people would not know about the system, so would end up having their organs donated against their wishes because they never had the chance to express a preference otherwise.
• Respect: It is possible to argue that we should prioritise the dignity of the dead, particularly because some religions state that the body must remain intact after death.
• Alternatives: Some people argue that we could instead encourage more people to sign up and opt-in to donate their organs, which would also help to solve the problem.

Should people be allowed to sell their organs in the UK?

Another important ethical debate is whether or not we should allow the sale of organs by living donors.

Some arguments in favour of legalising selling organs include:

• This would ensure that more organs are available
• It would discourage people from turning to the black market to sell their organs, which is dangerous and discourages people from seeking help for complications

Some arguments against legalising organ sales include:

• It is possible that, even if organs were sold to the NHS and allocated fairly, people in need may feel pressured to sell their organs for money
• It could be considered to be inherently unethical to sell organs as they are a part of someone’s body

What is living organ donation?

Living organ donation refers to the donation of a whole or partial organ from a living person to another person in need of a transplant. This type of donation is typically reserved for organs that can regenerate, such as the liver, kidney, and lung.

Living organ donation is a critical source of organs for transplantation, as the demand for organs far exceeds the number of organs available from deceased donors.

In addition, living organ donation can offer a number of advantages over deceased donation, such as the ability to plan the transplant surgery in advance, and the potential for better outcomes due to the quality of the donor organ.

However, living donation also carries some risks, both for the donor and the recipient, and careful screening and evaluation are essential to ensure the safety of both individuals involved.

How are donor organs allocated and who gets priority?

In the UK, various factors affect the extent to which someone can be prioritised for transplant receipt. It is important to note that these are factors that affect the extent to which the organ is likely to help that individual and last for an extended period of time. These include:

• Clinical necessity: Other treatment options should be exhausted before transplant is considered, given the scarcity of organs.
• Survival chances: Patients with significant other comorbidities, who may not survive surgery or survive for long after surgery, may be deprioritised.
• Support system: Patients should demonstrate that they have a support system that can help them through the long recovery process
• Risk factor exposure: It is important that patients show they can avoid relevant risk factors (eg abstaining from alcohol if they are receiving a liver transplant following a diagnosis of alcoholic liver disease) - this ensures that the transplanted organ is not likely to be damaged

Patients should not be prioritised or deprioritised for transplant based on the cause of their need for transplant unless that also affects any of the above four factors. For instance, someone should not be inherently deprioritised for a liver transplant because they were an alcoholic but may be deprioritised if they have shown that they are unable to stop drinking.

Pros and Cons of Organ Donation: Top Tips for Interview Questions

You could get questions about any of the above topics, or organ transplants more generally, in your medical school interviews. Some top tips to consider are:

1. Show off your understanding of the law and how it may change in the future
2. Give examples, either hypothetical or from the news/media/etc, to illustrate your points.
3. Recognise that issues surrounding organ transplant ethics are complex. Always consider all sides of an argument, and approach the discussion with respect. A good test for this is to imagine that someone affected by the issue is in the room with you.

Medicine Interview Questions and Answers on Organ Donation

Q: Should the UK have an opt-in or opt-out organ donation system?

A: This is a very complex issue, with plenty of arguments on both sides. Overall, I support the current opt-out system that exists in the UK.

There is a significant deficit in the supply of organs, and hundreds of people die every year waiting for a transplant. An opt-out system enables us to reach donors who otherwise may never have thought about donating, or were neutral on the topic and never signed up. This can add plenty of years to people’s lives, and save families from a lot of suffering. Even more, people would die while awaiting an organ without this system.

I understand that some may disagree with this if they are concerned about co-opting donors who would not consent to this. However, I think that there are ways of mitigating this. First, family members can opt out on behalf of the deceased. Secondly, we could advertise this system in places like doctors’ offices, schools, and on the census which all citizens are legally required to complete.

Whilst this may not allow us to reach everyone, it means that we should at least be very close. This, in my view, is worth it to help stop the significant organ deficit in the UK from getting worse. Therefore, I support the opt-out system.

Q: Is it right that alcoholic patients are deprioritised for liver transplants?

Ultimately, the prioritisation of patients for organs is a complex series of decisions and there are multiple factors that influence the answer to this question.

We must recognise that alcoholism is a form of addiction - which is a disease, not a choice, and tied to various genetic and socioeconomic factors. Therefore, we should not make these decisions in any way that assigns a moral judgement on people who are addicts.

However, it is also important to ensure that transplanted organs are allocated effectively, to provide the greatest possible benefit. Therefore, if a patient is still drinking and likely to damage the transplanted organ, it is right to allocate the liver to someone else.

Ultimately, recovering alcoholics should not be deprioritised for organ transplants and, to the best of my knowledge, currently are not. However, people who continue to drink should be deprioritised.
