Chronic diseases have become a major public health problem that endangers health. The development of information technology in the field of medical applications has brought new opportunities for the management of chronic diseases，and at the same time，the state has released policies and various localities actively explored to promote the development of chronic disease informatization. Cloud computing，big data and visualization technology，Internet of Things and mobile Internet，artificial intelligence and other information means are widely used in various places to strengthen chronic disease management by helping convenient diagnosis and treatment of diseases，disease monitoring and early warning，efficient pharmaceutical services，smart home medical services，patients self-management，regulatory assessment and evaluation，information exchange and sharing，and the whole process of health services. Informatization has improved the grass-roots governance capabilities of chronic diseases，the grass-roots service capabilities of chronic diseases，the convenience of chronic disease management services，the compliance and satisfaction of chronic disease patients，and reduced the economic burden of chronic disease patients. However，there are still problems such as insufficient interconnection and interoperability of information related to chronic diseases，lack of simultaneous reform among medical services，medical insurance and drug supply，insufficient application of data mining，and imperfect financing guarantee mechanism. Therefore，we should accelerate the mutual sharing of chronic disease data，strengthen the wordination between medical service，medical insurance and drug supply，accelerate the development and use of chronic disease data，rely on informatization to build chronic disease characteristic specialties，and improve the information input mechanism of chronic disease management，so as to further provide strong support for chronic disease management.
