Brief Summary

The heavy disease burden is mainly due to diabetic complications. Diabetes is a major risk factor for cardiovascular disease (CVD) and chronic kidney disease (CKD).China has been the largest absolute disease burden of diabetes in the world recently1. Diabetic patients with established CVD or CKD are bringing growing pressure upon our nation's healthcare expenditure1. However, the characteristic profile of Chinese diabetic patients who has CVD, CKD or at high risk of CVD remains unclear thus is in urgent need for in-depth investigation.In current China, however, the information regarding diabetes or non-diabetes patients who also had other comorbid conditions (e.g. established CV diseases, CKD or at high risk for such problem), is limited; the patient characteristics, treatment patterns and economic burden may not be fully understood.Therefore, based on TianJin regional database, the investigators will describe the demographic, clinical characteristics, treatment, and economic burden of disease of Chinese diabetic/non-diabetic patients with/without established CV disease, CKD, or at high CV risk including hypertension and hyperlipidaemia. And the investigators believe that the resulting findings will inform a comprehensive group of evidence users to achieve better healthcare for diabetes patients with established or at high risk of CVD or CKD.
