Among the various complications of diabetes mellitus, DKD is considered as a major threat and is one of the manifestations of diabetic microangiopathy. it is one of the main causes of death for patients with T2DM.~Albuminuria is the earliest manifestation of DKD, which is mostly asymptomatic at the early stage, if the albuminuria is poorly controlled, it may develop into clinical DKD. Therefore, it is very important to improve the patients' awareness of DKD, regularly screen early kidney diseases and use drugs rationally.~In order to promote the standardization of diagnosis and treatment of patients with DKD, improve the knowledge and screening rate of patients with DKD, help the formation of health literacy, healthy behavior and lifestyle, the investigators planned the study.~STUDY OBJECTIVES:~To understand the epidemiological disease burden of DKD in China, and to investigate the prevalence rate, awareness rate and screening rate of DKD;~To understand the treatment status of patients with DKD in China;~To provide real-world data on the efficacy and safety of SGLT2i in the treatment of DKD in China;
This is a large-scale, multi-center, observational study. It is planned to establish a large database of 10,000 patients with type 2 diabetes mellitus to investigate the prevalence, awareness and screening rates of diabetes kidney disease (DKD), and provide real-world data on the efficacy and safety of sodium glucose cotransporter 2 inhibitors (SGLT2i) in patients with type 2 diabetes mellitus (T2DM).
