Decision Aid to Technologically Enhance Shared Decision Making (DATES)

This study has been completed.

Physicians face a challenge in promoting colorectal cancer screening (CRCS) in the face of multiple competing demands. A decision aid (DA) that clarifies patient preferences and improves decision quality could aid shared decision making (SDM) and be effective at increasing CRCS rates. However, exactly how such DA improves SDM is not clear. This 4-year R01 study funded by the National Cancer Institute seeks to provide detailed understanding of how an interactive DA affects patient-physician communication and SDM, and ultimately CRCS adherence.

Condition Intervention
Colorectal Cancer Behavioral: Colorectal Web

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Prevention
Official Title: Decision Aid to Technologically Enhance Shared Decision Making

Primary Outcome Measures:
  • Number of Participants Reporting Preferred Screening Type as Reported by Chart Audits [ Time Frame: 6 months following intervention a chart audit will be conducted to determine if CRCS was completed. ]
    Chart audits were conducted 6 months after the participant's study visit to determine if screening had occurred and if the type of screen was the same as the participant's preferred type of screening.

Enrollment: 570
Study Start Date: May 2012
Study Completion Date: April 2015
Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Control
Same information is presented in the control website as is found in the intervention website, but no interactive component: preferences and risk assessment.
Active Comparator: Intervention with Colorectal Website
Intervention website includes an interactive component including preferences and risk assessment.
Behavioral: Colorectal Web
The intervention arm will allow participants on Colorectal Web to manipulate their preferences for CRCS

Detailed Description:
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.
