Description:Help on this term

The percentage of people who returned a valid National Bowel Cancer Screening Program (NBCSP) screening test and received a positive screening result (warranting further assessment) in a defined 12-month period

Rationale:Help on this term

The positive screening test rate determines the cancer diagnostic assessment workload and lesion detection rate. It is important that the accepted positivity range is reviewed, revised if necessary, and defensible.

Monitoring this is useful for program planning and quality assurance. Further, monitoring the positivity rate by various stratifications may reveal emerging positive or negative trends that need to be investigated and rectified if necessary.

As a measure of program performance, the screening positivity is presented for a defined 12-month period. To ensure the latest screening results are being monitored, this indicator counts all tests analysed in the defined period, not tests from those invited in the defined period; therefore, the cohort monitored is different from that in the participation indicator.
