Chronic Care Model has been designed to address this need. This study aimed to explore the lived experiences of the diabetes team and diabetic patients regarding the health care system after redesigning delivery system and supporting self-management based on the Chronic Care Model in Iran. <strong>Methods</strong>: Research was conducted with a qualitative descriptive approach in one of the Isfahan city clinics in 2018. The participants were diabetes team (composed of diabetes physician, nurse, assistant nurse and dean of the clinic) and 17 type- 2 diabetic patients who were selected through purposive sampling. Data collection was performed through semi-structured interviews and then were analyzed using content analysis with an inductive approach. <strong>Results</strong>: The findings of this study were composed of the following two main categories: (1) educational function change, including the sub-categories of evidence-based nurse education and patients’ demand to ongoing participation in the training classes; and (2) treatment and care method upgrade, including the sub-categories of nurse’s role change in a team approach, continuity in cares and upgrading patients’ self-care behaviors. <strong>Conclusions</strong>: Delivery system redesign and diabetes self-management support based on Chronic Care Model changed organizational structure and performance of the diabetes care system. It also reformed the structure of treatment providers from a vertical and hierarchical form to a team arrangement. Nurse’s educational function became evidence-based and patients’ self-care behaviors upgraded.http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2678http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2678/717718519
