Mobile Health Support

for Colorectal Cancer Screening

This study assesses the effectiveness of colorectal cancer (CRC) screening intervention, mobile Patient Technology for Health (mPATH™-Cloud), compared to usual care among subjects who are overdue for CRC screening according to recommendations of the United States Preventive Services Taskforce (USPSTF). The trial randomly selects and enrolls 1,000 eligible subjects served by one federally qualified health center (FQHC) in North Carolina. Subjects are randomized to two study arms, Usual Care (Arm 1) or Mobile Health Decision Support (Arm 2). Usual care consists of a visit-based screening recommendation to complete a stool test (e.g., FOBT, FIT, Cologuard) or referral to a screening colonoscopy. Subjects randomized to the Mobile Health Decision Support (Arm 2) are sent a message by text or US mail, depending on their preferred communication mode as indicated in the electronic health record (EHR), to visit the mPATH™-Cloud website. Subjects who engage with mPATH™-Cloud are invited to answer brief questions to confirm their eligibility and then view a short decision aid video designed to help people choose the CRC screening test (FIT or colonoscopy) that they would like to receive. After watching the video, subjects can choose a CRC screening test. Their primary care provider at the FQHC orders the appropriate test and, where indicated, refers the subjects to a colonoscopy. Subjects who request FIT screening and subjects who do not select any test receive a FIT mailed to their home address. The primary outcome of interest is CRC screening completion within 6 months after randomization as assessed by EHR chart review. A completed screening is any of the following: colonoscopy completion (regardless of indication); 2) at least one FIT test with a normal result; or diagnostic colonoscopy following an abnormal FIT result. We hypothesize that we will observe a higher CRC screening completion rate in the Mobile Health Decision Support intervention arm (Arm 2). This study includes up to three annual rounds of screening eligibility assessment and outreach. Repeated intervention rounds allow us to evaluate whether the intervention can improve adherence to USPSTF recommendations over time. During the 3-year intervention phase, Arm 1 receives usual care only.
