Description:Help on this term

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.

Rationale:Help on this term

The participation rate is a key indicator that measures the proportion of those invited who participate in the program. 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 two annual reports. This is consistent with other cancer screening program reporting.

National Health and Medical Research Council (NHMRC) guidelines recommend a two-yearly screening interval for colorectal cancer screening in Australia (ACN 2017), and a rollout for 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 off or suspend from the Program without completing the test will not be counted.

Denominator:Help on this term

The number of people invited in a defined 24-month period, excluding those who either opted off or suspended without completing a screening test.

People who opt off or suspend 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.
