The clinical audit cycle explained
The clinical audit cycle is the loop of setting standards, measuring practice against them, making changes and measuring again; HQIP describes it in four stages (planning, measuring performance, implementing change and sustaining improvement), and it only closes when you have evidence the change worked.
Stage by stage
HQIP's 2020 guide names the stages as preparation and planning, measuring performance, implementing change, and sustaining improvement. The first and last stages both mention repeated cycles, because the end of one round is the planning for the next.
In planning you choose the topic and the evidence-based standards, agree the aim and objectives, and design the method and data collection tool. In measuring you collect the data and compare it with the standards. In implementing change you turn the gaps into numbered recommendations and a SMART action plan. In sustaining improvement you collect evidence that the plan made a difference.
Why it is a spiral, not a circle
NICE's Principles for best practice in clinical audit (2002) describes the process as a cycle or spiral: each round aims for a higher level of quality than the last. That is why repeat data collection matters. It shows whether practice moved, and by how much.
NICE's book also says collecting data a second time after changes is central to assessing and keeping improvements, and that the same sampling, collection and analysis methods should be used so the two rounds can be compared.
When does the cycle close?
HQIP is explicit that the audit cycle is not complete until evidence has been obtained that the action plan improved quality. Evidence is usually a repeat data collection, but HQIP's reporting guide also accepts a summary of repeated plan-do-study-act cycles or annotated time-series data such as process control charts.
The stakeholder group decides whether the audit needs repeating and when, and whether ongoing monitoring would work better than a formal re-audit.
What the cycle is not
- Not a one-off snapshot: a single round with no follow-up measurement leaves the loop open.
- Not research: audit measures against an existing standard and does not allocate people to interventions.
- Not a blame exercise: the aim is to improve care against the standard, not to rank individuals.
Where Oriel fits
Oriel keeps each stage of the loop on record. The approved plan, the evidence for each case, who decided each finding and the signed-off report are all kept, with an append-only action log. An audit can be saved as a versioned pack, a schedule or a workflow and run again over a new period, so the second round reads the same systems with the same rules.
Schedules can notify people when compliance falls below a level you set. Oriel is a pilot shown on synthetic data and is not a medical device.
Questions
How many stages are in the clinical audit cycle?
HQIP's 2020 guide describes four: preparation and planning, measuring performance, implementing change, and sustaining improvement.
Is a run chart enough to close the loop?
HQIP's reporting guide accepts annotated time-series data such as process control charts, as well as a second round of data collection, as evidence of impact.

Oriel is a working prototype shown on a fictional demo hospital with synthetic data only. It is not a medical device and is not for clinical use. It drafts and flags for people to decide; it does not diagnose or change clinical records. A clinical safety case and information-governance approval come before any use with real patient data.
