The Bottom Line
- A QI project follows the <strong>PDSA cycle</strong>: Plan → Do → Study → Act.
- The minimum viable QI project can be designed in <strong>one weekend</strong> and executed over 4–8 weeks alongside clinical work.
- What matters for appraisal: <strong>clear aim, measurable outcome, evidence of change, and documented reflection</strong>.
Quality improvement is now a required component of most UK medical appraisals and specialty training portfolios. Many doctors dread QI because they imagine a 6-month research project. In reality, the best QI projects are small, focused, and directly relevant to your daily clinical work. The PDSA (Plan-Do-Study-Act) cycle gives you a framework that is both rigorous and practical.
1
Step 1 — Pick a problem you see every week
The best QI projects start with frustration: a process that wastes time, a common error you keep seeing, or a gap in care that patients experience. Examples: incomplete discharge summaries, delayed referrals for a specific pathway, inconsistent safety-netting documentation, or poor compliance with a prescribing guideline. If you care about the problem, the project will sustain itself.

Step 2 — Write a SMART aim statement
Your aim should be: Specific (what exactly will improve?), Measurable (what metric will you track?), Achievable (can you influence this?), Relevant (does it matter clinically?), Time-bound (over what period?). Example: 'Increase the proportion of discharge summaries completed within 24 hours from 60% to 85% over 6 weeks.'

Step 3 — PLAN: design the intervention
What single change will you test? Keep it small — one change per PDSA cycle. Examples: a checklist, a template, a reminder system, a brief training session, or a process redesign. Define: what you will do, who is involved, when you will measure, and what data you will collect.

Step 4 — DO: implement and collect data
Run the intervention for a defined period (2–6 weeks). Collect your outcome data consistently. Keep a brief log of what happened — including any unexpected barriers or adaptations. You do not need a massive dataset; 20–50 data points is often sufficient for a practice-level QI project.

Step 5 — STUDY: analyse what happened
Compare your outcome data to your baseline. Did the metric improve? By how much? What worked and what didn't? Were there unintended consequences? A simple before/after comparison with a chart or table is usually sufficient. You do not need statistical testing for most QI projects.

Step 6 — ACT: decide what to do next
Three options: (1) Adopt — the change worked, make it permanent. (2) Adapt — the change partly worked, modify and run another PDSA cycle. (3) Abandon — the change didn't work, try a different intervention. Document your decision and the reasoning. This is the 'closing the loop' that appraisers want to see.

Step 7 — Document for portfolio/appraisal
Write up: aim, baseline data, intervention, results, reflection, and next steps. Include at least one chart showing the change. Add a reflection paragraph covering: what you learned about improvement methodology, what you would do differently, and how this informs your future practice. Total write-up: 1–2 pages.
QI vs Clinical Audit — what's the difference?
Clinical audit measures practice against a defined standard (are we meeting the guideline?). QI goes further — it tests an intervention to improve practice. Both are valuable for appraisal, but QI demonstrates that you can drive change, not just measure compliance. If you have time for only one, a QI project with a PDSA cycle is more impressive than a simple audit.
Scope creep kills QI projects
The most common failure mode: starting with 'improve patient experience across the department' instead of 'reduce waiting time for triage by 10 minutes'. Keep the scope tiny. One metric. One intervention. One PDSA cycle. You can always do more cycles later. A completed small project is infinitely better than an abandoned ambitious one.
