NCT06444542

Brief Summary

There are significant barriers to colorectal cancer screening within underserved populations due to the cost, accessibility, and acceptability of screening methods. Patient-friendly approaches that minimize stress and discomfort for the patient are needed to enhance screening compliance and achieve an early diagnosis. The primary aim of this study is to examine whether the availability of a blood-based screening option, which can be done at the point of service and is familiar to patients, will improve patient compliance to recommended CRC screening

Outcome Measures

Primary Outcomes (1)

  • Patient preference for a blood-based screening option

    We will ask participants the following survey question: "Will you prefer to use the blood-based screening test for future colorectal cancer screening?" Response options range from 0 to 10 where 0 is "not at all" and 10 is "very much". We will split the response options at the median and categorize the measure into a "yes/no" response.
