| Number of AK diagnosed during RS FBSE | Total | |||
|---|---|---|---|---|
| 1–3 AK | 4–9 AK | ≥ 10 AK | ||
| AK detection in skin screening, n | 724 | 328 | 270 | 1322 |
| No routine care based prior AK diagnosis, n (%) | 556 (77) | 226 (69) | 136 (50) | 918 (69) |
| Previous routine care based AK diagnosis, n (%) | 168 (23) | 102 (31) | 134 (50) | 404 (31) |
| Diagnosis by GP, n (%) | 68 (40) | 45 (44) | 40 (30) | 153 (38) |
| Diagnosis by dermatologist,a n (%) | 60 (36) | 30 (29) | 48 (36) | 138 (34) |
| Diagnosis by both GP and dermatologist, n (%) | 40 (24) | 27 (26) | 46 (34) | 113 (28) |
FBSE, full‐body skin examination; GP, general practitioner. aAs derived from GP records. If dermatologist correspondence does not state AK, diagnosis is classified as AK according to the differential diagnosis of the GP.
