Patient-Centered Anticoagulation Self-Monitoring in Minority Patients

"Patient Self-Monitoring (intervention): entails 3 education sessions of 90-120 minutes each (week 0, week 2, week 4): 2 provided on site in clinic and 1 in the patient's home, during which, self-testing competency and barriers and facilitators to self-monitoring will be evaluated. Subjects will follow with weekly (or sooner, if clinically indicated) in-home self-monitoring and follow-up weekly phone calls over 6 months by clinical pharmacists to guide warfarin dosing and reinforce key educational messages.~Anticoagulation Clinic (control): subjects will have their INR tested in clinic monthly (or more frequently if clinically indicated) via the Coaguchek® point-of-care device (which is the standard of care in the Anticoagulation Clinic) and receive dosing instructions and standardized education related to warfarin by a clinical pharmacist who provides care in the Anticoagulation Clinic."
