The burden of diabetes on the health care system mandates efforts to more optimally treat those with the disease and to prevent its development in those at risk. Early and intensive intervention in patients with diabetes reduces the risk of microvascular and macrovascular complications and disease progression. Current challenges in diabetes management include: (1) optimizing the use of currently available therapies to ensure adequate glycemic, blood pressure, and lipid control and to reduce complications; (2) educating patients on diabetes self-management; (3) improving patient adherence to lifestyle and pharmacologic interventions; (4) reducing barriers to the early use of insulin; and (5) improving the delivery of health care to people with chronic conditions.
