The long-term goal of this research is to improve health outcomes in patients on chronic oral anticoagulationtherapy. My primary aim is to determine the impact on INR control resulting from the integration ofinformation on patient health literacy and numeracy, health knowledge and health beliefs regarding warfarintherapy into the clinical information provided to the pharmacist. The central hypothesis of this research isthat by expanding the clinical information available to incorporate information pertaining to patients' healthliteracy and numeracy, health knowledge and health beliefs, clinicians will be able to tailor educationalinterventions and decision-making to best fit the patients' needs. To test the central hypothesis, theproposed study will address the following three aims: (1) To determine if patient health knowledge, healthbeliefs, and health literacy and numeracy of warfarin therapy, when integrated into pharmacists' clinicalinformation, will impact patients INR control. (2) To determine if patient health knowledge, health beliefs, andhealth literacy and numeracy of warfarin, when integrated into pharmacists' clinical information, will impactpatient's knowledge of oral anticoagulation therapy. (3) To determine the cost implications resulting from theadditional process of collecting, analyzing and incorporating information on patient health knowledge, healthbeliefs, and health literacy and numeracy regarding warfarin therapy.
