The ultimate goal of health care providers in treating chronic diseases such as diabetes is to prevent complications by providing symptom relief and delaying disease exacerbation rather than curing the disease. For this, lifestyle habits such as eating habits, smoking, drinking, and exercise should be improved and drug therapy should be continuously implemented. For patient management and treatment, medication adherence affects disease progression, and long-term outcomes. Therefore, poor medication adherence will lead to exacerbation of the disease; as a result, the incidence of complications increases and medical costs increase. Although the first diagnosis of diabetes is important, it is more important to continue to care for and manage patients, so we are looking for ways to improve patient medication adherence.
