Preferred language spoken at home

Australians who preferred to speak a language other than English at home had a lower participation rate than those who preferred to speak English. They experienced the same screening positivity rate; however, those with a positive screening result had a lower follow-up diagnostic assessment rate and longer median time between a positive screen and an assessment (Table 4.4).

  1. Participation rates by preferred language spoken at home were estimated using 2021 Census proportions (see Table A4.1 and Appendix C for more information).
  2. Data for this indicator are not available.

Notes:

  1. The participation indicator PI 1 is reported against the period 2023–2024 with follow-up to June 2025. The screening indicator PI 2 is reported against the period 2024. The assessment indicators PIs 3 and 4 are reported against the period 2024 with follow-up to 31 December 2025. Incidence and mortality data are not currently available for reporting by preferred language spoken at home.
  2. Indicators PI 3–9 rely on information being reported to the NCSR (ACSQHC 2020). As this NBCSP form return is not mandated by the NBCSP, there may be incomplete form return and incomplete data. However, Participant follow-up function (PFUF) data are now used to supplement missing colonoscopy form data and MBS claims.
  3. PI 5a (adenoma detection rate), PI 5b (PPV of diagnostic assessment for detecting adenoma), PI 6a (bowel cancer detection rate), PI 6b (PPV of diagnostic assessment for detecting bowel cancer), PI 7 (interval cancer rate), and PI 8 (cancer clinico-pathological stage distribution) are not reported due to data incompleteness or unavailability.
