Recent studies demonstrated that successful chronic disease management requires a coordinated effort that includes health care providers who follow recent clinical guidelines in their everyday practice, educated patients who are adherent to their prescribed treatment plans, and comprehensive patient-provider communication. Studies employing telecommunication technologies have been successful in affecting the major components of chronic disease care, including physician practice patterns, patient adherence to therapy, and patient-provider communication. These studies were focused mainly on an improvement of a single component of the clinical care process. To date there have been no studies evaluating a coordinated approach that concurrently employs all of these components in an integrated framework linked to primary care. In this study researchers propose to evaluate a multi-component telemanagement system providing integrated support to both clinicians and patients in implementing hypertension treatment guidelines according to the JNC 7 Report.
