Abstract

Purpose: To understand patient experiences and persistent barriers to colorectal cancer (CRC) screening amid centralized outreach at urban family medicine practices.

Approach: Following a pragmatic trial assessing mailed fecal immunochemical test (FIT) outreach, we invited a subset of participants to complete a semi-structured qualitative interview and structured questionnaire.

Setting: Single urban academic healthcare system.

Participants: Sixty patients who were eligible and overdue for CRC screening at the time of trial enrollment.

Method: Using Andersen's Behavioral Model, we developed an interview guide to systematically assess factors shaping screening decisions and FIT uptake. Close-ended responses were analyzed using descriptive statistics. Qualitative data were analyzed using the constant comparative method.

Results: Most participants (82%) self-reported that they had ever completed any modality of CRC screening, and nearly half (43%) completed the mailed FIT during the trial. Most patients (60%) preferred FIT to colonoscopy due to its private, convenient, and non-invasive nature; however, persistent barriers related to screening beliefs including fear of test results and cancer treatment still prevented some patients from completing any form of CRC screening.

Conclusions: Mailed FIT can overcome many structural barriers to CRC screening, yet clear communication and follow-up amid centralized outreach are essential. For some patients, tailored outreach or navigation to address screening-related fears or other screening beliefs may be needed to ensure timely completion of CRC screening.
