EXPEDIT: Trial of Direct Home Delivery of Colorectal Cancer Screening Kit Without Pre-ordering
Study Details
Study Description
Brief Summary
The effect of mailing FIT with the invitation on participation and colonoscopy rates will be evaluated in a randomized controlled trial conducted in the Centre-Val de Loire (CVL) region, involving 64,000 people from the population eligible for colorectal cancer population-based organised screening program (CRC-PBOSP).
In the "C" control group, invitations, test delivery and reminders will be carried out in accordance with the CRC-PBOSP rules at the time of the study.
Intervention group "B" will evaluate two experimental modes of invitation with direct home mailing of the test:
-
Method "B1": invitation with test sent to home without prior information letter
-
Method "B2": information letter followed by invitation with test sent home, designed to optimize participation by first-time subjects (aged 50-51) invited to the CRC-PBOSP for the first time.
Ancillary studies will focus 1/ on acceptability of this intervention (qualitative study on a few general practitioners, gastroenterologists and invitees), 2/ on social and geographical inequalities of participation on a subsample of individuals included in EXPEDIT study using ecological indices (EDI, SCALE).

Other: Control "C" Usual care : Screening test (Fecal immunochemical test - FIT) delivery and reminders will be carried out in accordance with the Colorectal cancer population-based organised screening program (CRC-PBOSP) specifications at the time of the study. This arm is suitable for both the first screening round in 50-51 years old population, and for the subsequent screening rounds. |
Other: CRC screening invitation not including the screening test.
The invitation to CRC-PBOSP will only contain informations on how to get the screening test.
|
Experimental: Intervention "B1" FIT mailed at home within the CRC screening invitation without prior information letter. This arm is suitable for both the first screening round in 50-51 years old population, and for the subsequent screening rounds. |
Other: Mailing of FIT with invitation
The invitation to CRC-PBOSP will contain the CRC screening test.
|
Experimental: Intervention "B2" FIT mailed at home within the CRC screening invitation with prior information letter. This arm is suitable for the first screening round in 50-51 years old population only. |
Other: Mailing of FIT with invitation
The invitation to CRC-PBOSP will contain the CRC screening test.
Other: Information letter before invitation
An information letter will be sent to future invitees a few weeks before the invitation, to announce the mailing of the CRC screening kit.
