How to use this guide

You don't need to memorise every detail of every NHS issue. That's not what the assessors are looking for. They want to see that you can talk about a handful of current healthcare challenges with genuine understanding and thoughtful analysis. Pick 3 to 4 topics from this list, know them well, and be able to discuss the key arguments on both sides. That's far more impressive than having a surface level awareness of 15 things.

For each topic below, I've included what it is, why it matters, and an example interview question to practise with. If you want a detailed framework for structuring these answers, read our ethics guide since the same approach works for NHS knowledge questions.

1

NHS workforce crisis and staffing shortages

The NHS has a vacancy rate of around 6.9%, with hundreds of thousands of unfilled posts across doctors, nurses, and allied health professionals. The government's Long Term Workforce Plan aims to double medical school places to 15,000 by 2031, but training a doctor takes at least 5 years, so the effects won't be immediate. In the meantime, staff burnout is a serious issue. Junior doctors went on multiple rounds of strike action in 2023 and 2024 over pay that had fallen by over 26% in real terms since 2008. The strikes have been resolved for now, but the underlying tensions around pay, working conditions, and career progression remain.

Why it matters: Staffing drives everything. Waiting times, patient safety, staff morale, service availability. If there aren't enough doctors and nurses, everything else breaks down. As a future doctor, this is the system you're entering. Having an opinion on how to fix it shows maturity.

"What do you think is the biggest challenge facing the NHS right now, and what would you do about it?"

NHS waiting lists and the elective care backlog

As of 2025, around 7.4 million people were on the NHS waiting list for planned treatments like hip replacements, cataract surgery, and diagnostic tests. This number surged after COVID when elective procedures were paused, and while it's come down from the 2023 peak, it's still far above pre-pandemic levels. The NHS hasn't met the 18 week treatment target since 2016. The government is investing in surgical hubs (dedicated centres for planned operations, separated from emergency admissions) and Community Diagnostic Centres to try to bring the backlog down.

Why it matters: People waiting months or years for treatment experience worsening pain, declining mental health, inability to work, and sometimes their condition becomes harder or more expensive to treat. This isn't an abstract policy issue. It's real people's lives on hold.

"How would you explain to a patient why they've been waiting 18 months for a hip replacement?"

The assisted dying debate

In late 2024, MPs voted to progress the Terminally Ill Adults (End of Life) Bill, which would legalise assisted dying for terminally ill adults in England and Wales under strict safeguards. This is one of the most debated ethical topics in medicine right now. Supporters argue it's about patient autonomy and compassionate end of life care. Opponents worry about vulnerable people feeling pressured, the impact on the doctor-patient relationship, and whether palliative care should be improved first. The BMA (British Medical Association) has shifted from opposing assisted dying to adopting a neutral position, reflecting how divided the medical profession itself is.

Why it matters: This directly tests your ability to discuss a complex ethical issue with nuance. There's no "right" answer. The assessor wants to see that you can engage with both sides genuinely and reach a reasoned position.

"What are the arguments for and against legalising assisted dying?"
4

AI and technology in healthcare

Artificial intelligence is already being used in the NHS for tasks like analysing medical images, triaging patients, and predicting which patients are at risk of deterioration. AI can read certain types of scans faster and more accurately than humans in some studies. But there are significant concerns around data privacy, algorithmic bias (AI systems can perform worse for certain demographics if the training data isn't representative), accountability (who is responsible if an AI misses something?), and the risk of depersonalising care.

Why it matters: Technology will reshape medicine during your career. Showing that you understand both the promise and the risks makes you sound like someone who's thinking about the future of the profession, not just trying to get into medical school. The key nuance: AI should augment doctors, not replace them. The human relationship between a doctor and patient is something technology can't replicate.

"Do you think AI will ever replace doctors?"
5

Mental health and the NHS

Mental health services are chronically underfunded relative to physical health services, despite the NHS's stated commitment to "parity of esteem" between the two. Waiting times for talking therapies, CAMHS (Child and Adolescent Mental Health Services), and crisis services are often extremely long. The government has pledged additional investment, including 24/7 support through NHS 111 and more mental health specialist ambulances, but demand continues to outstrip supply. The post-pandemic rise in anxiety, depression, and eating disorders among young people has been particularly sharp.

Why it matters: Regardless of what speciality you end up in, you will encounter patients with mental health issues. A cardiologist, a GP, a surgeon. Mental health doesn't stay in its own lane. Understanding why services are stretched and what's being done about it shows that you see healthcare as a whole system, not just the speciality you happen to find interesting.

"Why do you think there's such a gap between physical and mental health provision in the NHS?"
6

Antibiotic resistance

Antibiotic resistance is sometimes called one of the biggest threats to modern medicine. Bacteria are evolving to resist the antibiotics we use to treat them, and the development of new antibiotics isn't keeping pace. MRSA is the most well known example, but the problem is far wider. The WHO has warned that without action, routine operations could become life threatening because we won't be able to prevent or treat infections. The UK has taken steps including the world's first "subscription model" for antibiotics, where the NHS pays a fixed annual fee for access to new drugs regardless of how much they're used, to incentivise pharmaceutical companies to develop them.

Why it matters: This is a great topic to discuss because it connects science, public health, ethics, and global cooperation. It shows you can think beyond individual patients to population level challenges. The key tension: how do you balance access to antibiotics for patients who need them now against preserving effectiveness for the future?

"What can be done to tackle antibiotic resistance?"

How to discuss these in an interview

When you're asked about an NHS topic, the assessor isn't testing whether you can recite facts. They're testing whether you can think critically about a real world issue. The best answers follow a simple structure: briefly explain the issue (show you understand it), explain why it matters for patients and healthcare workers, discuss what's being done or could be done about it, and acknowledge the complexity or trade offs involved.

Don't try to propose a grand solution to NHS funding in 5 minutes. That's not what they want. They want to see that you're engaged, informed, and capable of thinking about these issues like someone who will one day work within this system. The same principles that apply to ethics questions apply here: identify the issue, explore the perspectives, and reach a thoughtful conclusion.

Pro Tip

Pick your 3 strongest topics from this list and practise answering questions about them out loud. Set a 3 minute timer. If you can explain the issue, discuss the key arguments, and give a thoughtful conclusion in 3 minutes, you're in great shape. If you're running to 5 or 6 minutes, you're going into too much detail. Be concise.

Staying up to date

NHS hot topics change. New issues emerge, old ones evolve. The topics in this article are current as of early 2026, but if your interview is later in the year, it's worth checking for any major developments. The easiest way to stay informed is to read the BBC Health section once a week and follow NHS news on social media. You don't need to be obsessive. 10 minutes a week of casual reading will keep you ahead of 90% of candidates.

For the full picture on interview preparation, make sure you've also read our complete MMI preparation guide, our 7 common mistakes article, and our "why medicine?" guide. Together with this NHS knowledge, those four articles cover everything you need to know.

The point of knowing about the NHS isn't to sound impressive. It's to show that you're genuinely interested in the system you're asking to join. That curiosity is what separates applicants who want to be doctors from applicants who want to have been doctors.
