Three educational interventions for the control of essential hypertension in ambulatory patients were based on analyses of the educational needs of patients and providers. The educational program increased reported compliance with medication, improved the proportion of patients losing weight, and improved appointment keeping. Most important, there was a favorable effect on blood pressure (BP) control. The proportion of patients with BP under control in the group assigned to all three interventions increased by 28% (from 38% to 66%), while the proportion in the control group receiving standard medical therapy with no educational interventions remained unchanged at 42%.
