Background: Although several guideline-recommended colorectal cancer (CRC) screening modalities have been shown to reduce CRC incidence and mortality, adherence remains below U.S. public health goals. Patient navigation services have been shown to improve CRC screening completion. Patient navigation services, including outbound phone, text, and e-mail reminders, and inbound phone support (>200 languages) are included with all mt-sDNA test (Cologuard) orders. A website and financial assistance (upon request and qualification) are also available for patients. We developed a survey, informed by behavioral theory, to identify psychosocial and communication factors associated with completion of mt-sDNA screening including questions to evaluate awareness and use of navigation services. Methods: Adults aged 45-75 years, with a US postal address, who received a valid order for mt-sDNA screening between 5/21-9/21 were eligible for sampling. RTI administered the survey between 3/22-6/22. Participants had the option to complete electronic- or paper-based surveys. We conducted crosstabulation with Chi Square to assess whether awareness and use of navigation services was significantly associated with (a) test completion within 6 months of the order date and (b) likelihood of future mt-sDNA use. Results: 2,973 participants completed the survey (RR= 21.7%; 65.15% by web and 34.85% by paper). Responders and non-responders did not differ significantly by age or sex. For each navigation service, awareness was significantly higher among those who completed the mt-sDNA test compared to those did not. Across all services, awareness was significantly higher among respondents reporting they were ‘very likely’ to complete mt-sDNA if recommended by a healthcare provider in the future than all other responses combined. A significantly higher proportion of completers (vs. non-completers) reported receiving the email reminder, using the Cologuard website, and using the English language inbound phone support. A significantly higher proportion of those “very likely” to complete mt-sDNA screening in the future reported receiving the email reminder, using the Cologuard website, and using the English language inbound phone support. Conclusions: Awareness and use of patient navigation services was associated with higher completion of the mt-sDNA test and with greater likelihood of future mt-sDNA test use. Patient navigation services comprised of evidence-based strategies, such as reminders, support patient adherence to CRC screening.
