Qualitative Outcomes of Colorectal Cancer Screening Outreach Using Patient Navigation to Follow-Up Colonoscopy in Rural Primary Care Practices.

Background/Objectives: Despite its effectiveness, colorectal cancer (CRC) screening rates are suboptimal in the United States. Navigating patients towards complete CRC screening can be effective in addressing barriers. However, to date, much research on patient navigation has occurred in urban settings or large health systems, thereby missing some populations that could benefit the most. Methods: We report on a patient navigation program delivered by clinic staff during a large pragmatic study to improve CRC screening in rural Medicaid populations. We use qualitative and implementation data from interviews, contract logs, and tracking systems to explore the context, barriers, and facilitators of patient navigation, as well as feasibility and acceptability for rural primary care clinic partners. Results: A total of 35 patients were eligible for navigation following an abnormal FIT (n = 26, 74%) or due to higher CRC risk (n = 9, 24%); only 8 of the 14 intervention clinics (57%) had any eligible patients. Of the 26 patients who needed navigation following an abnormal FIT, 13 patients (50%) received navigation, and 3 (23%) completed a colonoscopy; all 9 of the higher-risk patients received navigation, but none completed colonoscopy. Several barriers impacted adherence to the navigation protocol, such as staffing disruptions, limited colonoscopy availability, patient mistrust, and data tracking limitations. Our findings also highlight implementation facilitators, including protocol adaptations and cross-team collaborations for low-volume settings. Conclusions: Future models to increase patient navigation in rural settings could include more centralized system-level interventions that build on relationships between clinics and colonoscopy providers or payers and leverage quality improvement best practices.
