Impact · Method
How we measure
Six metrics, each with a definition and a stated limit.
The metrics
Definitions matter more than values
| Metric | Definition | Limit |
|---|---|---|
| Coverage | Screened as a proportion of the roll | Absence is not refusal; we record them separately |
| Findings rate | Coded findings per hundred screened, by category | A screening cohort is not a population sample |
| Referrals raised | Referrals generated per hundred screened | Depends on clinical threshold, which varies |
| Referrals closed | Referrals with a confirmed outcome | Unknown outcomes are reported as unknown, not assumed |
| Card issue | Cards personalised and handed over | Issued is not the same as retained |
| Repeat participation | Beneficiaries returning in a later cycle | Only meaningful from the second cycle onwards |

Coverage
Why the denominator is reported, not just the count
The number we watch most
The gap between raised and closed
This is the honest measure
Any programme can raise referrals. The proportion that reach a confirmed outcome is what distinguishes a health service from a screening exercise, and it is the number we report first.
