Diabetes is a long-term chronic disease. The patients need to correct "knowledge and action" lifestyle in order to achieve effective blood glucose control. Upon the general control of diabetic patients in Taiwan, however, glycosylated hemoglobin (HbA1c) is not satisfactory. One of the important reasons is the low rate of insulin injection. For the use of insulin, the patient has many misconception. The patients in the clinic need to spend a lot of time to explain and description, but the results are not necessarily good. So we hope that in this part of the health education activities through organized groups Videos to assist doctors and patients as a bridge of communication, to enhance diabetes doctor thus contributing to glycemic control results.
