This report covers activity from 1 April 2022 to 31 March 2023 inclusive.

  • As of 31 March 2023, screening coverage was 68.2% across Wales, and exceeded 66% in all Health Board regions. This figure combines the proportion of 25-49 year olds screened in the previous 3.5 years, and the proportion of 50-64 year olds screened in the previous 5.5 years. This is known as ‘age-appropriate’ coverage.
  • In 2022-23 228,143 individuals aged 25-64 were invited for screening.
  • 170,892 individuals were screened in 2022-23, (including those with inadequate results). This number includes individuals who were screened during the year 2022-23 and does not reflect all the individuals that were invited in that year.
  • Laboratories examined 173,494 samples from Welsh residents in 2022-23.
  • In 0.3% of tests the final result was ‘inadequate’. ‘Inadequate’ means that the sample quality was insufficient for producing either a HPV or cytology result, as appropriate’
  • The Positive Predictive Value (PPV) correlates high grade cytology with high-grade histology. For 2021-22, the PPV for Wales is 83.9%.
  • 9,185 new patients were seen at colposcopy clinics in Wales in 2022-23, 67.7% having been directly referred by Cervical Screening Wales and 32.3% for clinical reasons, e.g. symptoms or an abnormal appearing cervix.
