Durability of FIT Screening After Cessation of a Screening Outreach Intervention

INTRODUCTION: Organized outreach to increase CRC screening using mailed FIT tests has been shown to be effective, but durable changes to screening behavior after cessation of screening is not known. METHODS: In this study, after cessation of funding for an organized cancer screening outreach program, we evaluated whether adherence to screening remained elevated. Patients aged 50–75 years eligible for CRC screening from eight safety net clinics were randomly assigned to outreach intervention vs usual care alone in 2016 to 2018; the primary outcome analyzed was the difference in the cumulative proportion of completed FIT screening between study assignments 1 year after study cessation. RESULTS: Despite higher rates of FIT screening for patients who were randomly assigned to the outreach intervention, FIT completion was not significantly different between the group that received the outreach services versus the usual care group (28.3% vs 29.8%, p = 0.158). CONCLUSION: Outreach campaigns and their activities must be sustained to maintain improved rates of screening participation.
