Introduction/Objectives: Despite compelling evidence of clinical and economic benefits, adherence to colorectal cancer (CRC) screening remains low. Increasing public awareness through various outreach methods may improve screening uptake. The objective of this study was to evaluate the uptake of non-invasive multi-target stool DNA (mt-sDNA) by different outreach methods in an average-risk employer population. Methods: This retrospective observational study included CRC screening-eligible individuals aged ≥50 years insured by the Metropolitan Nashville Public Schools (MNPS) employee healthcare plan. The study intervention arms included population-based outreach and office visit-based interaction. The mt-sDNA completion rate (proportion of individuals who return the mt-sDNA kit after consenting to have it shipped to their home), proportion of patients who performed follow-up colonoscopy after a positive test, and time to follow-up colonoscopy were assessed. Results: A total of 167 mt-sDNA kits were shipped to eligible participants (aged 50-64 years) in the population-based outreach arm. In the office visit-based interaction arm, a total of 132 mt-sDNA kits were shipped to eligible participants (aged ≥50 years). The mt-sDNA completion rate was significantly higher for office visit-based interaction as compared to population-based outreach (76.8% vs 53.5%; P < .001) among those aged 50 to 64 years. While all patients aged 50 to 64 years with a positive mt-sDNA result received a follow-up colonoscopy in both arms, the median time to follow-up colonoscopy was shorter among the population-based outreach (55 vs 136 days; P < .05). Conclusions: Office visit-based interaction was associated with a higher mt-sDNA completion rate as compared to the population-based outreach among average-risk, CRC screening-eligible individuals aged 50 to 64 years old.
