Objective/Hypothesis: Our hypothesis is that offering annual colorectal cancer screening with fecal occult blood tests to eligible adults aged 50 and over during annual nurse-run influenza vaccination clinics will result in increased colorectal cancer screening rates, reaching populations that have been under-screened in the past. Our overall objective is to develop, implement, test, and disseminate this intervention using an annual fecal immunochemical test for occult blood (FIT) at Kaiser Permanente (KP) Northern California.
