Why this matters for your practice
The PDSA cycle is the practical engine behind continuous quality improvement. It gives a practice a repeatable way to make a change, see whether it actually worked, and only then roll it out. For accreditation, that structure is gold, because it produces exactly the documented evidence assessors want: a plan, an action, a measured result, and a decision. A practice that runs improvement work as PDSA cycles rarely struggles to evidence its CQI obligation.
It also reduces risk, because changes are tested small before being adopted across the whole practice.
The four steps
- Plan: decide what you are going to change and what you expect to happen. Set a clear aim and how you will measure it.
- Do: make the change on a small scale and collect data on what happened.
- Study: compare the result against what you expected. Did it work? What did you learn?
- Act: decide whether to adopt, adapt, or abandon the change, then start the next cycle.
The power is in the loop: most improvements take several cycles before they are ready to embed.
A simple example
A practice wants to improve recall of overdue cervical screening. Plan: test sending an SMS recall to one month's cohort. Do: send the messages and record responses. Study: measure how many booked compared with the usual letter. Act: if SMS performed better, adopt it across all recalls and begin a new cycle on a related gap.
How it fits with accreditation
A PDSA cycle is one of the recognised continuous quality improvement activities, alongside clinical audits and significant event analyses. Documenting the four steps, with dates and a measured outcome, turns an everyday improvement into accreditation evidence.
Common mistakes
- Skipping Study, so there is no measurement and no proof it worked.
- Going big too early, rolling out a change before testing it small.
- One cycle only, when most improvements need several.
- No documentation, leaving nothing to show at the survey.
Frequently Asked Questions
What is a PDSA cycle?
A PDSA cycle is a four-step quality improvement method (Plan, Do, Study, Act) for testing a change on a small scale, measuring the result, and deciding whether to adopt it. It is the methodology RACGP assessors most readily recognise for continuous quality improvement.
What are the four steps of PDSA?
The four steps are Plan (decide the change and how to measure it), Do (make the change on a small scale and collect data), Study (compare the result with what you expected), and Act (adopt, adapt, or abandon the change and begin the next cycle).
How is PDSA used for RACGP accreditation?
A documented PDSA cycle is a recognised continuous quality improvement activity. Recording the plan, the action, the measured result, and the decision provides the evidence of a completed improvement cycle that assessors look for.
