Project Objectives: Lowering blood pressure in hypertensive patients unequivocally decreases the incidence of stroke and cardiovascular events and is highly cost-effective. The majority of patients with blood pressure above the treatment target do not have their anti-hypertensive medications appropriately intensified at clinician visits. A reduced frequency of treatment intensification is alternatively termed 'clinical inertia'. Our preliminary results show that clinicians' knowledge of hypertension management guidelines is limited, and few clinicians report following the guidelines consistently. We propose to conduct a randomized controlled trial involving PCPs in VISN 1 to determine whether ISE can (1) increase knowledge of the appropriate treatment of hypertensive patients, (2) reduce clinical inertia in hypertension management, and (3) improve the blood pressure control in hypertensive patients.
