Increasing Uptake of Colorectal Cancer Screening in Ontario
A study testing FOBT kit and Mailed invitation in people with Colorectal Disorders, run by Sunnybrook Health Sciences Centre at 1 site in Canada.
Trial summary
The investigators hope to determine whether the addition of an FOBT kit and educational materials to a second mailed invitation compared to a second mailed invitation alone increases use of appropriate screening tests (FOBT for average risk or colonoscopy if increased risk) by eligible persons within 6 months of the… Read more about this study

About this study
The investigators hope to determine whether the addition of an FOBT kit and educational materials to a second mailed invitation compared to a second mailed invitation alone increases use of appropriate screening tests (FOBT for average risk or colonoscopy if increased risk) by eligible persons within 6 months of the second mailing in: (1)Non-responders to an initial mailed CRC screening invitation from their family physician and, (2)Those who responded to the initial mailed CRC screening invitation and are due for repeat screening (i.e., "recall" patients). In addition, the investigators will also explore the impact of the investigators intervention in likely under-screened groups such as those living in more remote areas of the province and those with low socio-economic status as well as assessing the cost-effectiveness of this strategy.

What is being measured
The primary outcome is the main question the study is designed to answer.
Uptake of appropriate CRC screening
The primary outcome will be the uptake of appropriate screening (FOBT testing or if there is a positive family history, of colonoscopy) within 6 months of the mailing as determined by from OHIP and CCO data.
Measured: Within 6 months of the mailing
Secondary outcomes (1)
Uptake of lower gastrointestinal investigations
The secondary outcome will be the uptake of lower gastrointestinal investigations (colonoscopy for an indication other than family history or colonoscopy done outside of CIRT, flexible sigmoidoscopy, barium enema) within 12 months, respectively, of the mailing as determined by the administrative data (CIRT, OHIP procedure or radiology code).
Measured: Within 12 months of the mailing

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The investigators hope to determine whether the addition of an FOBT kit and educational materials to a second mailed invitation compared to a second mailed invitation alone increases use of appropriate screening tests (FOBT for average risk or colonoscopy if increased risk) by eligible persons within 6 months of the second mailing in: (1)Non-responders to an initial mailed CRC screening invitation from their family physician and, (2)Those who responded to the initial mailed CRC screening invitation and are due for repeat screening (i.e., "recall" patients). In addition, the investigators will also explore the impact of the investigators intervention in likely under-screened groups such as those living in more remote areas of the province and those with low socio-economic status as well as assessing the cost-effectiveness of this strategy.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Uptake of appropriate CRC screening (time frame: Within 6 months of the mailing). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01629004, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Dec 2014; AzTrials last refreshed its copy on 8 Nov 2026.
