The Specific Aims of the proposed project are to: Aim 1: Develop a patient-reported, EHR-integrated, personalized risk assessment module to provide tailored disease risk and risk reduction information for four common diseases (breast cancer, colorectal cancer, coronary heart disease, and type II diabetes) for the patient and his/ her PCP. Aim 2: Measure the reach and effectiveness of this integrated risk assessment module by conducting a cluster randomized controlled trial (RCT) of adult primary care patients in the Brigham and Women's Primary Care Practice-Based Research Network. Aim 3: Evaluate facilitators and barriers to the adoption and implementation of this integrated risk assessment module.
