Project Overview +

DATES (Decision Aid to Technologically Enhance Shared Decision Making) is an interactive decision aid website for colorectal cancer, designed to be used prior to a clinic visit to clarify each patient's preferences and promote shared decision-making. The website uses a unique interactive Preference Elicitation Tool, which helps patients determine the colorectal cancer screening test option that best matches their preferences.

Aims +

Aim 1. To measure the impact of ColoWeb (CW) on patient uptake of colorectal cancer screening (CRCS).

Hypothesis 1: Patients in the Intervention Arm will have higher rates of CRCS adherence at the 6 month follow-up than those in the Control Arm.

Aim 2. To evaluate the impact of CW on patient determinants, patient preference, and patient intention before the patient-physician encounter.

Hypothesis 1: Patients in the Intervention Arm will show greater improvement from baseline in patient determinants (knowledge, attitude, subjective norm, perceived self-efficacy) compared to the Control Arm after the web intervention and before the patient-physician encounter.

Hypothesis 2: Patients in the Intervention Arm will be more likely to have a preference for a particular CRCS test option than those in the Control Arm after the web intervention and before the patient-physician encounter.

Hypothesis 3: Patients in the Intervention Arm will have higher intention to undergo CRCS than those in the Control Arm after the web intervention and before the patient-physician encounter.

Aim 3. To evaluate the impact of CW on shared decision-making, concordance, and patient intention during and after the patient-physician encounter.

Hypothesis 1: Patients in the Intervention Arm will experience a higher level of shared decision-making than those in the Control Arm.

Hypothesis 2: Higher rates of concordance will be reached between the patient's preferred CRCS test and the physician's recommended CRCS test in the Intervention Arm than those in the Control Arm.

Hypothesis 3: Patient's intention to undergo CRCS after the patient-physician encounter will be predicted by the study arm, degree of shared decision making, concordance, and interaction between shared decision making and concordance.

Participants +

Participants are under age 50, scheduled for a doctor visit, do not have a current colorectal cancer screening, and have no history of colorectal cancer.

Intervention +

This project tests an updated version of ColoWeb that is highly innovative. The new website incorporates interactive patient preference clarification and risk assessment that provide real-time information to the patient and the physician during the clinic visit, making ColoWeb more applicable to real-world primary care practices.

A 2-armed randomized control trial compares the Intervention Arm using ColoWeb to the Control Arm using a non-interactive control website, Standard Web, in 10 primary care practices in Metro Detroit with a large African American population.
