What is the difference between a clinical audit and a quality improvement project? When might you choose one over the other?
- This question tests a distinction that many candidates conflate.
- Audit measures practice against a standard; quality improvement (QI) aims to change practice through iterative testing of interventions.
- Interviewers want to see that you understand both methodologies, that you know when each is appropriate, and that you can explain the practical difference.

How to approach this Shared interview question
This quality improvement question is common in NHS interviews because it reveals how you think under interview pressure, not just what facts you can recall. Use "What is the difference between a clinical audit and a quality improvement project?" as the anchor for a concise answer with a clear opening, a clinical or professional structure, and a reflective close.
What the panel is testing
A strong quality-improvement answer uses method as well as enthusiasm. Be clear about the problem, baseline measurement, intervention, re-measurement, and how the change was made sustainable. For shared NHS interview questions, keep the answer portable across roles. Use one relevant example, explain your reasoning, and make the link to safe patient care explicit.
- Separate audit, QI, research, and clinical governance clearly so the panel can follow your reasoning.
- Use a real cycle: baseline, intervention, re-measurement, learning, and sustainability.
- Link the project back to patient safety, service reliability, or measurable outcomes.
How to structure your answer
For a quality improvement prompt, aim for a short opening sentence, then two or three evidence-led points, then a final reflection. If you use STAR, keep the result and reflection as strong as the situation. If it is a clinical scenario, say what you would do now, what you would do next, and how you would keep the patient safe while help is coming.
- Open by naming the main issue in the question.
- Give a structured response rather than a memorised script.
- End with escalation, documentation, learning, or follow-up.
Common mistakes to avoid
The weakest answers usually stay too vague, ignore the specific role, or miss the safety issue hidden in the question. Do not use this page to memorise a perfect paragraph. Use it to rehearse the shape of a safe answer, then adapt it to your own experience and the post you are applying for.
