The MISTER B Trial

MISTER B was a preclinical, telephone-based patient navigation intervention designed to encourage colorectal cancer (CRC) screening among older Black men. Participants were 50 years of age or older, were not up-to-date on CRC screening, had uncontrolled high blood pressure, and had a working telephone. Participants were randomized into three groups: 1) patient navigation by a community health worker for CRC screening; 2) motivational interviewing for blood pressure (BP) control by a trained counselor; or 3) both interventions. CRC screening was assessed at 6-month follow-up. Participants in the navigation interventions were significantly more likely to be screened for CRC than those in the motivational interviewing only group.
