Clinical inertia now is the main cause for long-term poor of blood glucose control in T2DM, and leads to an increased risk of diabetes-related complications, and can bring heavy social and economic burdens. The various stages of diabetes treatment and the clinicians, nursing staff, patients themselves, medical system and social environment involved in the treatment process can all become factors that affect clinical inertia. Taking effective measures to overcome diabetes-related clinical inertia is an important part of improving the long-term prognosis of patients. It is of great significance to improve patients treatment compliance, the overall rate of reaching the standard of blood glucose, and prevent the occurrence and development of diabetes complications. This requires the joint efforts of many parties.
