Increasing Uptake of Colorectal Cancer Screening in Ontario

Not Applicable

Completed

• Conditions: Colorectal Disorders

• Registration Number: NCT01629004
• Lead Sponsor: Sunnybrook Health Sciences Centre

Brief 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 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.

Primary Outcome Measures

Name	Time	Method
Uptake of appropriate CRC screening	Within 6 months of the mailing	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.

Secondary Outcome Measures

Name	Time	Method
Uptake of lower gastrointestinal investigations	Within 12 months of the mailing	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).
