Reminder Modality for CRC Screening

Reminders for FIT (Fecal Immunochemical Test) Kits Via Different Modalities: a Randomized Controlled Trial

This is a randomized controlled trial that will evaluate the effectiveness of different reminder modalities for a population-based mailed FIT program at the VA Puget Sound among average risk Veterans who are due for annual colorectal cancer (CRC) screening.

This is a prospective, randomized controlled trial that will evaluate the effectiveness of two different reminder modalities in improving adherence to annual CRC screening.

Veterans eligible for enrollment into the trial will be randomized in a 1:1:1 allocation using permuted block randomization (with random block sizes of 3 and 6) to the following interventions:

1. Control arm: No reminder

   a. Intervention Type: No intervention

2. Arm 2: Automated phone reminder

   a. Intervention Type: Standard reminder via phone (audiocare)

3. Arm 3: Text reminder a. Intervention Type: Standard reminder via text (VEText)

Randomization will be stratified within arms by prior screening status (prior screener vs. never screener)

Eligible participants are automatically enrolled in this project. We are unable to enroll participants upon request.

Inclusion Criteria:

• Veterans assigned to a primary care provider at the VA Puget Sound as of January 1, 2021

Exclusion Criteria:
