Australian Health Performance Framework: PI 2.1.3a–Cancer screening rates, National Bowel Cancer Screening Program participation rate, 2020
Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||AHPF PI 2.1.3a–National Bowel Cancer Screening Program participation rate, 2020|
|Synonymous names:||NBCSP participation rate|
|Registration status:||Health, Standard 13/10/2021|
The proportion of people invited to screen through the National Bowel Cancer Screening Program (NBCSP) in a 24-month period who returned a completed screening test within the defined 24-month period or the following 6 months.
The participation rate is a key indicator that measures the proportion of those invited who participate in the NBCSP. Without participation, the NBCSP cannot achieve early detection. The program should therefore monitor participation to ensure acceptability, equity and uptake with the aim that reductions in incidence, morbidity and mortality can be achieved.
Participation is the number of people screened, not the number of tests completed, and is divided by the number of people invited.
The indicator reporting period is 24 months due to the rescreening interval and results in a 'rolling' rate, i.e. a particular year would be included in 2 annual reports. This is consistent with other cancer screening program reporting.
National Health and Medical Research Council (NHMRC) guidelines recommend a 2-yearly screening interval for colorectal cancer screening in Australia (ACN 2017), and a rollout of this is currently underway. Accordingly, this participation indicator counts participation activity over a 24-month period and uses a 6-month follow-up period to ensure those invited have had time to respond.
Although it would be ideal to adjust for people who do not screen because they participate in other forms of screening or surveillance, this is not currently possible due to restrictions in the data available. However, people who opt out or defer from the NBCSP without completing the test will not be counted.

Collection and usage attributes
|Population group age from:|
|Population group age to:|
Excludes people who were screened outside the National Bowel Cancer Screening Program. People who opt out or defer from the NBCSP without completing the test are also excluded.
Analysis by Primary Health Network (PHN), remoteness and Socio-economic Indexes for Areas (SEIFA) Index of Relative Socio-economic Disadvantage (IRSD) is based on Statistical Area Level 1 (SA1) or postcode of residential address at the time of screening.
The target population list is compiled from those who were registered as an Australian citizen or migrant in the Medicare enrolment file, or were registered with a Department of Veteran's Affairs gold card. Due to the phased roll-out of the NBCSP, target age groups vary between years:
100 × (Numerator ÷ Denominator)
The number of target-age people invited to screen through the NBCSP in a 24-month period who returned a completed screening test within the defined 24 month period or the following 6 months.
|Numerator data elements:|
The number of target-age people invited in a defined 24-month period, excluding those who either opted out or deferred without completing a screening test.
People who opt out or defer are excluded from the denominator as they may be already participating in other forms of screening or surveillance due to non-asymptomatic reasons. Therefore, the denominator is closer to a true population screening scenario.
|Denominator data elements:|
2014–2015 to 2017–2018—Nationally, by:
2014–2015 to 2017–2018—State and territory.
2014–2015 to 2017–2018—Primary Health Network (PHN).
Disaggregations by socio-economic status use the 2011 version of SEIFA for 2014–2015, 2015–2016 and 2016–2017, and the 2016 version of SEIFA for 2017–2018.
Data are presented as numbers of participants and participation rates (percentage).
Some disaggregation may result in numbers too small for publication.
