The Committee of Clinical Practice Guidelines of the Korean Diabetes Association revised and updated the ‘3rd Clinical Practice Guidelines’ at the end of 2010. In these guidelines, the committee recommends active screening of high risk individuals for early detection and added HbA1c level as a diagnostic criterion of type 2 diabetes to produce a more practical approach based on clinical studies performed in Korea. Furthermore, committee members emphasize that integrated patient education for self-management is an essential part of patient care. The drug treatment algorithm was also updated based on the degree of hyperglycemia and patient characteristics.
