Notes on the data: Screening programs - Bowel screening

Total males/ females/ persons who participated in the National Bowel Cancer Screening Program (NBCSP), 2016 and 2017

 

Policy context:  Colorectal cancer (CRC), also known as bowel cancer, is one of the commonest forms of cancer in Australia, with around 80 Australians dying each week from the disease. Bowel cancer can be treated successfully if detected in its early stages, but currently fewer than 40 per cent of bowel cancers are detected early. Screening has been shown in randomised trials to reduce the incidence of and mortality from CRC [1] [2].

Since 2006, the Australian Government has initiated a limited CRC screening program,which aims to reduce the incidence and death from bowel cancer, by using a one-time immunochemical faecal occult blood test (FOBT) for people aged 50, 55 and 65 years. The second phase of the National Bowel Cancer Screening Program (NBCSP) commenced on 1 July 2008 and offered testing to people turning 50 years of age between January 2008 and December 2010, and those turning 55 or 65 between July 2008 and December 2010. With ongoing funding, the program expanded to include those turning 60 years of age from 2013 and those turning 70 years of age from 2015. In 2017-18 the program introduced biennial screening which upon full implementation (by 2020) will be offered to all Australians aged between 50 and 74 years, as per the recommendations by the National Health and Medical Research Council for two-yearly screening [3]. About 5.5 million NBCSP screening tests have been completed since the program’s commencement in 2006, with about 280,000 participants having a diagnostic assessment to follow up a positive screening result [4].

In addition to the NBCSP, a variety of FOBT kits are available in Australia to screen for bowel cancer either available over the counter from pharmacies, through medical practitioners, or through other programs such as BowelScreen Australia, an education and screening initiative run by The Pharmacy Guild of Australia, and BowelCare, a community service project of various Rotary clubs and districts. The data contained within this report only represent participation within the NBCSP implemented by the Australian Government in partnership with the state and territory governments, not the other mentioned programs operating within the community.

Notes:  Where there are fewer than six events (invitees, participants) in an area, the data is suppressed to protect confidentiality. In addition, the current NBCSP data is presented over two calendar years - 2016 and 2017, hence it is not comparable with the previous release for 2014/15 (one financial year).
