Part 1 • See the questions

The Medibuddy 2027 Combined Infection Training ST4 Question Bank

The interview has three stations with five questions and takes around 45 minutes, so you have a limited window to deliver the high-scoring answers you need to do well. That means every point has to land, and knowing how to structure each answer is essential. That's why each of our 40-plus scenarios comes with a model answer, written by candidates who scored highly in the 2026 Combined Infection Training ST4 interview, so you know exactly how to approach every question the interviewers throw your way.
What's inside

What's included in the Combined Infection Training ST4 Question Bank

There's nothing worse than getting to the interview and being handed a scenario you've never seen before. The panel can draw on clinical, registrar, presentation, suitability and ethical themes across the three stations, so the safest approach is to revise across all of them. We provide scenarios for every part of the interview, including the common ones and the more unusual cases that have come up before, so you don't get caught out.

Clinical Scenarios

Infection and general medical cases where you play the registrar, each with a worked answer showing how to structure your response.

Medical Registrar Suitability

Managing a ward and a multidisciplinary team, discharge planning and the acute take, with model answers that show you're ready to work as a medical registrar.

Presentation & Suitability

The three-minute presentation on a recent development, and questions on your motivation for the infection specialties, with guidance and model answers.

Ethics, Professionalism & Governance

Unprepared ethical and professional questions, with structured model answers so you can reason through them clearly on the day.
Reflecting the ST4 structure
The ST4 interview has the addition of a Medical Registrar Suitability station, opening with a one-minute overview of your acute take experience. Our scenarios are built around this, alongside the clinical, presentation, suitability and ethical themes.
Try it

Try an example Combined Infection Training ST4 question

This is an example from the Medical Registrar Suitability station, which explores how you manage a ward and a multidisciplinary team, including safe discharge planning.

The panel works through a series of questions about running the team and getting patients home safely.

How would you approach them?

Question
What do you need to safely discharge a patient home, and which teams would you liaise with?
Example answer
The patient must first be medically fit, meaning they are likely to keep improving or hold steady without needing inpatient medical intervention, though some care can continue at home.
  • Home-based options: outpatient IV antibiotics, district nursing, ambulatory care review or intermittent return for outpatient therapies.
  • Function: physiotherapy and occupational therapy to assess ongoing needs and home modifications, especially after a long or ITU stay.
  • Feeding: speech and language therapy if swallowing is a concern, and dietetics for nutrition.
  • Medications and logistics: the ward pharmacist to reconcile and document discharge medications, and the ward clerk or discharge coordinator for transport, identified early.
Throughout, I would keep the patient and their next of kin updated on the likely discharge date.
Question
A patient is the main carer for their partner and is admitted acutely. What concerns would you have?
Example answer
My concern is the safety of their dependent while they are in hospital.
  • At admission, assess the level of care they normally provide and how it will be covered, whether through temporary family arrangements or formal carers, to prevent a second admission of the dependent.
  • At discharge, make sure they are genuinely able to resume their caring role, or that ongoing care is in place until they are well enough to do so.
Question
An unwell patient will remain on your ward over the weekend. How do you ensure appropriate review?
Example answer
It depends on the weekend cover arrangements, but I would make sure the patient is seen appropriately.
  • Use the formal weekend handover, verbal or digital, explaining the background, what I expect over the weekend, how senior the reviewer should be and specifically why they need review.
  • An SBAR handover is an effective way to structure this.
  • If they are notably unwell, involve critical care outreach if available, to support early escalation.
Question
How do you effectively estimate a patient's length of stay?
Example answer
I would avoid giving guarantees, as every course differs.
  • Offer a typical estimate for their condition, with the caveat that individual recovery varies.
  • Where there are specific rate-limiting factors, such as awaited investigations or interventions, I would explain these.
  • If I am uncertain, I would say so, and offer to ask the consultant for a more specific answer.
Question
How do you ensure good handover to primary care, and whose responsibility is it?
Example answer
Effective handover matters, so the patient is not left to remember their whole admission themselves.
  • A good discharge summary explains the purpose and duration of the stay, the relevant investigations and results, and any future plans for outpatient management.
  • It is the whole team's responsibility to ensure quality, which as a registrar includes training junior colleagues and periodically reviewing what is produced.
  • Writing a running discharge plan on the daily ward round, added to on senior reviews, makes summaries easier and captures follow-up accurately.
Question
How do you balance your medical knowledge with the patient's beliefs in shared decision-making?
Example answer
I would give the patient the benefit of my knowledge and balanced information, then honour their autonomy.
  • Their priorities may differ from mine, and autonomy means their informed choice takes precedence.
  • I would still be full and frank about the benefits, risks and any reasons I might not recommend a course of action.
  • Shared decision-making is an ethical necessity, and it also makes patients more likely to adhere to a plan they have genuinely chosen.

That's one scenario. There are over 40 more.

How we keep our Question Banks up to date

The Combined Infection Training ST4 interview changes from year to year, and the biggest fear for any candidate is getting to interview day and realising you've revised with a question bank that's totally outdated.

That's why we review and update every Question Bank twice a year, so you know you're revising with scenarios that are likely to come up. We do this in April after the previous year's interviews, and again in the autumn when the new recruitment guidance is published.

For 2027, this process kept the Question Bank aligned with the ST4 three-station format, including the Medical Registrar Suitability station, so you always practise with the format the panel is using now.
Updated for 2027 Interviews
Part 2 • Practise them live

The only interview resource where you can practise live with other candidates from across the country

Our Combined Infection Training ST4 Question Bank tells you exactly how to answer real interview scenarios. But how you practise with them will determine how many marks you score. Simply reading answers off a screen won't prepare you for the intense scrutiny you'll face in the interview. And only practising with the same few colleagues or friends limits the amount of feedback you'll get. Medibuddy gives you unique access to Combined Infection Training ST4 candidates across the country, so you can learn from a variety of perspectives and hear a far wider range of feedback than your own circle could ever give you.

Study Groups
When you prepare in isolation, you're relying on your own interpretation of the interview process, which is one of the quickest ways to get found out on the day. Study Groups connect you with other doctors across the country who are also applying to Combined Infection Training ST4, so you can engage and network with people preparing for the same interview as you. Everyone brings different experience from different hospitals and deaneries, meaning you won't ever miss out on the key bits of information that could swing the interview in your favour.
Live MocksBeta
Candidates who don't take part in mocks often struggle to adapt to the pressure of the interview. Your knowledge might be correct, but without convincing delivery the interviewers will score you poorly. The best way to improve your delivery is to take part in as many live mocks as possible, which is why we haven't put a cap on how many you can do. We also know how difficult it can be to organise mocks with other people, so all you have to do is join the waiting room and we'll match you with a different Combined Infection Training ST4 candidate each time. Take turns as both the interviewer and candidate on real Question Bank scenarios, so you can see exactly how other candidates perform in real time, while refining your own interview technique.
Peer FeedbackBeta
Preparing alone means you won't know how you're coming across during the interview. And preparing with the same few candidates means you'll miss opportunities to improve, which is why it's so important to get as many opinions as possible on your performance. With Medibuddy, you can record a mock and submit it for feedback from other candidates on the platform, so you receive a wider range of feedback and refine your answers with each person you practise with. Reviewing other people's mocks is just as valuable, as it shows you how strong candidates handle the same scenarios, which is one of the fastest ways to improve.

Our model answers are structured against those criteria, so you know exactly what a strong, well-organised answer looks like at each station.
Get ready

How to prepare for the Combined Infection Training ST4 interview

Start with the Question Bank

Work through over 40 scenarios across all three stations, each with a worked answer from a candidate who scored well in the 2026 interview. Start by reading how a strong answer is formed, then think about how you'd deliver it.

Talk the hard ones through in Study Groups

Study Groups are your biggest opportunity to network and connect with other candidates sitting the same interview as you. Everyone on the platform is in the same boat, so don't be scared to get involved and ask questions. Someone in your study group might just help you work through a scenario you've been struggling with.

Rehearse out loud in Live Mocks

Live mocks are where you begin to put everything you've learned into practice, and we know from experience that those who practise with a wide range of candidates usually do the best. Organise mocks with people from one of your study groups, or get matched with a random Combined Infection Training ST4 candidate, then take turns as interviewer and candidate using real scenarios until answering out loud under pressure feels normal.

Get reviewed with Peer Feedback before the day

Once you've recorded a mock, you can have other community members review it. This lets you see how you come across to other people, and gives you time to refine your delivery as you revise, rather than being caught out on the day. Reviewing other people's mocks is just as crucial, as you see how other candidates navigate the same scenarios.
