Systems for Care of Hypertension in the United States

Control of hypertension in recent clinical trials varies from 48% to 65%. However, in community care of hypertension in the United States, estimates of control of hypertension are far lower. The United States has no single system of care; however, several care systems can be identified for comparison, such as the Department of Veterans Affairs, managed care organizations, and the Indian Health Service. This review compares control of hypertension in certain centers in these systems with that achieved in clinical trials and in the community at large. Certain components of care systems are assessed for their contribution to the control of hypertension. The author concludes that for community control of hypertension to approach that achieved in clinical trials, the use of physician extenders, together with reduced or minimal cost of medication, improved education of providers with feedback, and computerization of management systems will be needed. In addition, specific interventions targeted to medically underserved groups will be required.
