Decider Guider - Primary Care


This study aims to increase the number of insured, primary care patients who complete a colorectal cancer (CRC) screening. This study integrates an innovative preference elicitation methodology, conjoint analysis, into a decision tool to help primary care patients clarify their preferences for CRC screening tests. The two sites participating in this study also allow for a more racially/ethnically diverse audience than other Decider Guider studies.


Aim 1. To evaluate the effectiveness of a preference-tailored intervention vs. standard information delivered via computer for increasing patient adherence to CRC screening guidelines in a randomized controlled trial in two racially/ethnically diverse geographic locations.

Aim 2. To 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. To conduct a cost effectiveness analysis of a preference-tailored strategy for increasing CRC screening utilization within a primary care setting.


The study will recruit 325 people per site: 1) members of the Health Alliance Plan (HAP) within Henry Ford Health System (HFHS) in Detroit, MI, and 2) members of the San Francisco Community Health Network (SFCHN) affiliated with San Francisco General Hospital in California.
