Diabetes educators give patients with diabetes the knowledge, skills and tools they need to manage their diabetes. Also, they can help these patients avoid many of the complications associated with the disease. The diabetes education team is involved not only in coordinating the ongoing care of patients, but also in educating and counseling patients on medication and management of illness. This systematic review suggests the benefit of diabetes education on glycemic control and health outcome when compared with usual care. Additional studies are needed to delineate these findings further. (J Korean Diabetes 2013;14:194-198)
