2015 Colorectal Cancer Screening Health Indicator Report

Purpose of the Health Indicator Report

The purpose of this Health Indicator Report is to provide information about the percentage of screen-eligible adults in Halton Region who were up to date with colorectal cancer screening.

Background

Regular screening can help to detect colorectal cancer early, when it is more treatable. Cancer Care Ontario recommends that people at average risk be screened with a fecal occult blood test (FOBT) every two years from ages 50-74, followed by a colonoscopy if there are abnormal FOBT results. Screen-eligible individuals are considered up to date if they have had a FOBT in the last two years, or a colonoscopy in the last ten years, or a flexible sigmoidoscopy in the last five years.

This Health Indicator Report uses administrative data from Cancer Care Ontario. For more information on cancer in Halton Region, please see the 2008-2012 Halton Region Cancer Incidence and Mortality Report.

Key Findings

Trends Over Time

  • 63% of Halton screen-eligible adults and 59% of Ontario screen-eligible adults were up to date with colorectal screening in 2013. This difference was statistically significant.
  • In both Halton and Ontario, the percentage up to date with screening gradually improved from 2009 to 2013. This increase was statistically significant.

Sex

  • In 2013, screen-eligible females in Halton were more likely than screen-eligible males to be up to date with colorectal cancer screening. This difference was statistically significant.

Age

  • In 2013, the likelihood of being up to date with colorectal cancer screening increased among Halton adults as age increased. Halton screen-eligible adults aged 65-69 and 70-74 were more likely than adults of all younger age groups to be up to date with colorectal screening. These differences were statistically significant.

Municipality

  • In 2013, the percentage of screen-eligible adults who were up to date with colorectal screening was higher in Oakville compared to all other Halton municipalities, and higher in Burlington and Halton Hills compared to Milton. These differences were statistically significant.

Income

  • In 2013, the percentage of screen-eligible adults who were up to date with colorectal screening increased as neighbourhood income increased. These differences were statistically significant when comparing residents of the lowest-income neighbourhoods to residents of the highest-income neighbourhoods.
