Brief Summary

Complete and timely colonoscopy after an abnormal stool-based colorectal cancer screening test results in early detection, cancer prevention, and reduction in mortality, but follow-up in safety-net health systems occurs in less than 50% at 6 months. The proposal will implement multi-level approach consisting of a stepped-wedge clinic-level intervention of team-based best practices co-developed with primary and specialty care, a patient-level technology intervention to provide enhanced instructions and navigation to complete diagnostic colonoscopy, and a mixed methods evaluation to explore multi-level factors contributing to intervention outcomes. Developing a solution to this high-risk and diverse population has the potential to translate to other health systems, support patient self-management, and address other patient conditions.

Outcome Measures

Primary Outcomes (1)

  • Colonoscopy completion

    Wait time for routine colonoscopy is often less than 6 weeks and less than 2 weeks if one is willing to take an afternoon appointment. Completion of colonoscopy will be captured by extracting pertinent colonoscopy elements

    6 months after abnormal FIT result

Secondary Outcomes (3)

  • Quality of bowel preparation

    At time of colonoscopy procedure

  • Referred to GI for colonoscopy

    6 weeks after abnormal FIT result

  • Scheduled by GI for colonoscopy

    8 weeks after GI referral
