A Patient Portal-Based Commitment Device to Improve Adherence with Screening for Colorectal Cancer: a Retrospective Observational Study.

Background: Despite significant investment in colorectal cancer (CRC) screening, 40% of US adults are not up-to-date. Commitment devices, which are psychologically tailored approaches to enforce health goals, may be an effective method to increase CRC screening.

Objective: Compare the effectiveness of a commitment device (patient self-ordering fecal immunochemical test (FIT) kits) to standard CRC screening outreach.
