Background. The life-saving benefits of colorectal cancer (CRC) screening can be maximized only if screening is completed at recommended intervals. The fecal immunochemical test (FIT), an inexpensive stool-based test recommended yearly, is the primary screening modality in many Federally Qualified Health Centers (FQHCs) and remains underutilized. To inform system interventions, we sought to identify patient perspectives on factors that influence the likelihood of repeated FIT screening over time in a large FQHC. Methods. Between September 2022 and March 2023, we conducted semi-structured interviews with patients who were due for FIT screening and completed at least one prior FIT test at a large FQHC that serves a primarily Latino population in Los Angeles County. Our interview guide explored patients’ perceived barriers and facilitators to repeat FIT over time and experiences with FIT clinic processes of care. Audio-recorded interviews were conducted in patients’ preferred language (English or Spanish), transcribed, and translated. Transcripts were coded using ATLAS.ti, and themes were summarized. Results. Among 17 interview participants, the majority were female (82%), Latino (94%), and Spanish-speaking (88%). The median age was 57 years (range 52-70), and 41% had an 8th grade education or less. Interviews revealed that patient, family, and provider/system factors influenced receipt of sequential rounds of annual FIT CRC screening. At the patient level, perceived importance of disease prevention and early detection on the part of patients facilitated proactive engagement in regular screening. Additionally, many patients thought the process of FIT completion and return was easy, although some patients did express low confidence in stool sample collection and time and work constraints impeding in-person FIT return. Another recurrent theme was motivation from family, both direct support (assistance with FIT completion and transportation to clinic) and indirect motivation (an intrinsic desire to stay healthy for family). At the provider/system level, language discordance hindered communication with providers, and in-language FIT instructions and availability of bilingual staff to translate were identified as facilitators. Patient suggestions to improve FIT completion included client text and letter reminders when due for CRC screening; print education that underscores the purpose of screening; and appointment consolidation for cancer and other preventive care screenings. Conclusion. Interventions to improve regular FIT-based CRC screening may benefit from emphasizing the importance of early detection; improving patient knowledge and confidence in how to perform stool sample collection; family support; and language-concordant staff and resources for multi-lingual and medically underserved populations.
