Brief Summary
-----------------
The China Alliance for Type 1 Diabetes (CAT1D) is committed to exploring and implementing the model of graded diagnosis and treatment of type 1 diabetes and comprehensive management of outpatient service, carrying out a series of educational activities for patients, and cooperating in the development of multi-center prospective clinical research on type 1 diabetes.

Detailed Description
-----------------
Through the CAT1D, expand the cohort construction of type 1 diabetes patients and first-level relatives in China, establish the electronic information database of type 1 diabetes, and lay a foundation for obtaining the research data of type 1 diabetes in China. observe and study the occurrence and development rules of acute and chronic complications of type 1 diabetes in China, analyze the influencing factors, and provide intervention means for reducing acute complications and preventing chronic complications. Through the established management platform and structured education system, verify and promote the comprehensive management mode based on structured education, and build a standard treatment plan and process based on evidence-based science and suitable for Chinese people and medical background. By using mobile health (mHealth) and Artificial Intelligence (AI) technologies, a new mode of intelligent structured education is established, which provides a new way to explore the individualized education management mode and improve the outcome of chronic diseases through modern technology.
