Decider Guider - VA


Colorectal cancer (CRC) is the third most prevalent cancer in the U.S. Dept. of Veteran Affairs (VA) and the second most costly cancer. This study aims to increase the number of VA patients who complete a CRC screening. It integrates an innovative and flexible preference elicitation methodology, conjoint analysis, into a decision tool to help VA patients clarify their preferences for characteristics of CRC screening tests.


Aim 1. Evaluate the effectiveness of a preference-tailored intervention vs. standard information delivered via computer for increasing VA patients' adherence to CRC screening guidelines in a randomized controlled trial.

Aim 2. Assess the impact of the intervention on patient perceptions of informed decision making, knowledge about CRC screening, decisional conflict and satisfaction, and intention to get screened 3 days after a primary care visit.

Aim 3. Conduct a cost effectiveness analysis of a preference-based strategy for increasing CRC screening use across the VA.


Five hundred people who are part of either the Ann Arbor or Pittsburgh VA health care systems, 50-79 years of age, have never been screened for CRC, or are out of date for CRC screening, have no personal history of CRC or colon polyps, and have no family history of CRC.
