Patient-Provider Communication and Colorectal Cancer Screening Completion Using Multi-target Stool DNA Testing

Abstract

AbstractColorectal cancer (CRC) screening continues to be underutilized in the USA despite the availability of multiple effective, guideline-recommended screening options. Provider recommendation has been consistently shown to improve screening completion. Understanding how patient-provider communication influences CRC screening can inform interventions to improve screening completion. We developed a behavioral theory-informed survey to identify patient-provider communication factors associated with multi-target stool DNA (mt-sDNA) screening completion. The survey was administered by RTI International between 03/2022 and 06/2022 to a sample of US adults ages 45–75 who received a valid order for mt-sDNA screening with a shipping date between 5/2021 and 9/2021. Respondents completed an electronic or paper survey. Multivariable logistic regression was used to identify patient-provider communication factors associated with mt-sDNA test completion. A total of 2973 participants completed the survey (response rate, 21.7%) and 81.6% of them (n = 2427) reported having had a conversation with provider about mt-sDNA testing before the test was ordered. Having a conversation with the provider about the test, including discussions about costs, the need for follow-up testing and test instructions were associated with higher odds of test completion and being “very likely” to use the test in the future. Lack of discussion about advantages and disadvantages of available CRC screening options and lack of patient involvement in CRC screening decision-making were associated with reduced odds of test completion and likelihood of future use. Healthcare providers play a key role in patient adherence to CRC screening and must be appropriately prepared and resourced to educate and to engage patients in shared decision-making about CRC screening.
