Follow-up colonoscopy after abnormal stool-based colorectal cancer screening (e.g., fecal immunochemical test (FIT)) results in early detection of colorectal cancer (CRC), prevention of CRC, and reduction in CRC mortality. FIT is a commonly utilized screening test that can be performed at home, is inexpensive, scalable, and often adopted in health systems where colonoscopy resources are scarce. Despite evidence that timely colonoscopy is necessary after an abnormal FIT result, completion of colonoscopy occurs in less than 50% of patients at 6 months and varies significantly by clinic and health systems. In addition to understanding the meaning of an abnormal FIT, three care transitions must occur smoothly for the patient: colonoscopy referral, scheduling, and attendance. However, multilevel factors influence missed follow-up, and multilevel solutions are needed along the care continuum to address clinic-, provider-, and patient-level factors that impair or delay colonoscopy completion.
IMProving Adherence to Colonoscopy through Teams and Technology (IMPACTT), proposes to close gaps and reduce disparities in CRC screening by improving the completion of diagnostic colonoscopy following abnormal FIT in vulnerable populations using a multilevel approach consisting of interventions at the clinic-, provider- and patient-level. The specific aims are 1) to evaluate the effect of a clinic-level intervention targeting primary care providers and staff to adopt "best practices" to support colonoscopy completion in patients with abnormal FIT results, 2) to determine the effect of a patient-level technology intervention with enhanced instructions and navigation for patients with abnormal FIT to complete a diagnostic colonoscopy, and 3) to explore the multilevel implementation factors contributing to intervention outcomes using mixed methods.
