Actual (reported)This study will compare patient adherence to different colorectal cancer (CRC) screening tests to identify the most cost-effective strategy to decrease mortality from CRC. We hypothesize that different types of tests will have different adherence rates, that these rates will alter the cost-effectiveness analysis, and that we can identify patient variables associated with non-adherence to specific CRC screening strategies.

Actual (reported)Adherence to colorectal cancer (CRC) screening, defined as completion of the screening strategy (the subject agrees to pursue/scheduled by the primary care provider).
Initial adherence measured at one year following enrollment. We have secured additional study funding that will allow us to extend the follow-up period for two more years, so we will measure programmatic adherence to CRC screening strategy over a 3-year period.

Preventive Intention: Of those who agree to colonoscopy or FOBT, the proportion of patients who have colonoscopy scheduled or take home FOBT cards.

Preventive Behavior: Of the subjects with a positive FOBT result, determine the proportion adhering to the follow-up colonoscopy.
