Brief Summary

Less than half of all positive fecal immunochemical testing (FIT)s are followed-up by colonoscopy, thus limiting the full potential of colorectal cancer (CRC) screening to reduce mortality. Given the need for coordination in order to achieve high rates of follow-up, multilevel approaches are needed. Such approaches could be particularly beneficial in communities and populations that experience cancer disparities and have fewer specialty providers, but most data focuses on large systems or urban areas. The academic-community health system collaboration is uniquely poised to address this research and service gap. The persistent poverty and health disparities in rural Southern Illinois set the stage for truly impactful research. The investigators' approach will serve as a model for multilevel interventions in rural settings, inform future work addressing other health disparities, and fill a gap in rigorous trials of CRC screening follow-up in rural areas.

    Completion of follow-up (estimated to be 44 months)

Study Arms (1)

Primary Care Clinics

EXPERIMENTAL

* Southern Illinois Healthcare System will contact the site management and ask for participation in the study * Eligible providers and staff will be identified by clinic management. The research coordinator will work with the clinic to schedule a virtual site visit(s). The study team will interview providers and staff at the beginning and/or end of each active intervention period to assess knowledge and attitudes about CRC screening and follow-up processes, the Consolidated Framework for Implementation Research (CFIR) constructs such as role clarity within the clinical team, and satisfaction with the intervention and implementation. Post-implementation surveys will also ask about work-arounds and adaptations of the intervention tools and perceived efficacy.

Other: Colorectal Cancer Toolkit

Interventions

The intervention toolkit will include patient education materials and supportive materials for providers. Tracking systems and supports will be jointly developed with participating clinic and providers, in order to maximize their existing systems and develop processes that meet their needs and preferences, and training will be offered to help providers/teams efficiently use the tracking system and clinic resources. The study team will provide technical assistance and support through email, phone and zoom to support the clinic in their implementation process.
