Patient Preferences for Colorectal Cancer Screening Tests in Light of Lowering the Screening Age to 45 Years

BACKGROUND & AIMS: In 2021, the US Preventive Services Task Force lowered the colorectal cancer (CRC) screening age to 45 years. We used conjoint analysis, a method that assesses complex decision making, to update our understanding on people's CRC screening test preferences in the context of new guidelines.METHODS: We conducted a conjoint analysis survey among unscreened individuals & DDAG;40 years at average risk for CRC to determine the relative importance of screening test attributes in their decision making (eg, modality, effectiveness at reducing CRC risk, bowel prep). We also performed simulations to estimate the proportion of people who would prefer each US Multi-Society Task Force (MSTF) on CRC-recommended test. The analyses were stratified among those aged 40-49 years (newly or soon-to-be eligible for screening) and & DDAG;50 years (have been eligible).RESULTS: Overall, 1000 participants completed the conjoint analysis (40-49 years, n = 456; & DDAG;50 years, n = 544). When considering all 5 US MSTF-recommended tests, there were differences in test preferences between age groups (P = .019), and the most preferred test was a fecal immunochemical test (FIT)-fecal DNA every 3 years: 40-49 years, 34.6%; Z50 years, 37.3%. When considering only the US MSTF tier 1 tests, most 40-to 49-(68.9%) and Z50-year-olds (77.4%; P [ .004) preferred an annual FIT over a colonoscopy every 10 years.CONCLUSIONS: Our findings suggest that more than one-third of people may want to do a FIT-fecal DNA every 3 years for their CRC screening. When only considering US MSTF tier 1 tests, three-fourths of people may prefer an annual FIT over colonoscopy. Further research examining CRC screening test preferences among broader populations is warranted to inform and enhance screening programs.
