Decision Aid to Technologically Enhance Shared Decision Making

This two-armed randomized controlled trial (300 patients/arm) will compare Colorectal Web
(CW), the interactive DA, to a non-interactive control website in ten practices in Metro
Detroit. Patients will be adults aged 50 years and over, not current on CRCS. In the clinic
before the patient-physician encounter, participants will complete a Patient Baseline
Survey. They will be randomized to CW or the control website. Data will be collected after
the patient reviews the respective website (Post-Intervention Survey), during the
patient-physician encounter (digital audio recording), and after it (Post-Encounter Survey).
Chart audit will be performed six months after the encounter to determine whether the
patient underwent CRCS.
