Colon Cancer Screening
Conditions
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.
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.

Study design
Intervention model description
This is a stepped wedge trial where clusters of sites sequentially enter the intervention. Independent samples of patients are enrolled within a cluster at each set interval of time thus, it is analyzed as a repeated cross-sectional study.
Eligibility
Inclusion criteria
for Primary Care Clinic Sites * Physician Hospital Organization (PHO) affiliated with Southern Illinois Healthcare
Exclusion criteria
for Primary Care Clinic Sites * Not a part of the PHO Inclusion Criteria for Physicians and Staff at Primary Care Clinic Sites * Employment at the relevant clinic at the time of the study
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Referrals for Colonoscopies After Positive Fecal Immunochemical Test | Within 60 days after receipt of positive FIT/FOBT | * Patients between 07/01/2021 - 12/31/2024 that had a fecal immunochemical test (FIT)/fecal occult blood test (FOBT) test performed with a positive result and had an ambulatory referral to Gastroenterology within 60 days of getting the results from the lab test. * Separate data for the Arms cannot be provided, as referrals were not able to be obtained from registry data due to unanticipated registry provider changes prior to study start \& major delays \& staff shortages due to COVID shutdowns, which prevented the collection of colonoscopy referrals. The referral data was obtained from the hospital sites that used EPIC but could not be differentiated by arms. Data for the remaining outcome measures was able to be differentiated by arm as the data came from the registry versus EPIC. |

Participant flow
Pre-assignment details
A total of 52 primary care clinics participated in the study. 39 primary care clinics only provided control data. 13 primary care clinics provided control data and participated in the intervention (4 clinics in Step Wedge 1 and 9 clinics in Step Wedge 2). Participants were counted only once during the study (when data was first collected) and did not overlap between period years.
