Abstract

This trial tested a multicomponent intervention to increase colorectal cancer (CRC) screening among underserved patients. Participants were randomized to: (1) physician + patient intervention, (2) physician-only intervention, or (3) usual care (UC). Study outcomes included patient knowledge, physician recommendation of CRC screening, and screening completion via colonoscopy or stool tests. Among 538 participants, those exposed to the physician + patient intervention had significantly increased knowledge over patients in physician-only (p=.0008) or UC arms (p=.0003). However, there were no statistically significant differences in completion of CRC screening, with 10%, 20%, and 16% of UC, physician-only, and physician + patient participants screened, respectively. In UC, all completed screenings were colonoscopy, whereas in the physician-only and physician + patient arms, 39% and 46% of completed tests were via stool test, respectively. The multicomponent intervention did not increase overall CRC screening, yet results underscore the need to provide patients options for completing CRC screening.
