The implementation of the national strategy to actively respond to the aging population is a requirement of the report of the 20th National Congress of the Communist Party of China. In this regard, the Ministry of Civil Affairs, the Central Political and Legal Commission, the Central Civilization Office and other 10 departments jointly issued the Guiding Opinions on Carrying out Visiting Care Services for the Elderly with Special Difficulties, proposing to establish and improve the visiting care service mechanism for the elderly living alone, empty nest, left behind, disabled, severely disabled, and special family planning families through more than three years of efforts, and further enhance the sense of gain, happiness sense of security. It can be said that the elderly with special difficulties are the vulnerable group among the elderly, and most of them are faced with such problems as poor physical condition, limited or lost mobility, difficulty in seeking medical care, and no accompanying and comfort. To help solve the difficulties of the elderly with special difficulties in providing for the elderly at home, and to strengthen the functions of providing for the elderly to cover the bottom line and protect the basic is to build a safe levee for the bottom line of people's livelihood. At present, the service supply for the elderly with special difficulties in China has some problems, such as low degree of refinement, outstanding formalization of service, lack of demand management awareness, etc., which is difficult to reflect the demand preference of the elderly with special difficulties. In addition, the service level between different regions is uneven, service supply is insufficient and surplus, and service efficiency and quality are low. To implement the national strategy of actively responding to the aging population, we need to use technology to enable the elderly with special difficulties to visit care services, timely understand their needs for food, clothing, housing, medical treatment, social security benefits, life care, rehabilitation care, etc., timely identify, effectively prevent, and safely resolve the security risks of the elderly with special difficulties at home, so that they can live in peace, tranquility, and comfort. Use informatization to improve the data element system, and establish and improve the normalized and long-term visiting care service mechanism. The population information, health information, service information, consumption information and other data element systems of the elderly with special difficulties cannot establish a unified big data center due to the division and protection of departments, which hinders the effective connection between service supply and demand. Therefore, it is necessary to establish a sound national basic database for the elderly with special difficulties, and coordinate the information of civil affairs, public security, streets, communities, medical institutions, insurance institutions and other departments. In the existing health elderly care service system, a complete database of the elderly with special difficulties has been established based on the national elderly care service information system of the "Golden People Project" and the thorough investigation of the elderly with special difficulties at the community level. In the database, the elderly with special difficulties are classified and refined according to their personal conditions, and their life and medical needs are dynamically obtained and analyzed. On this basis, relying on the elderly care information system to link elderly care institutions, hospital systems, community services and other support systems, provide sophisticated, comprehensive, real-time and dynamic visit care service support for the elderly with special difficulties, and explore the formation of a normalized and long-term mechanism. Empower the needs of the elderly with special difficulties by leveraging big data, and give consideration to diversified and personalized visiting care services. The service system for the elderly with special difficulties is difficult to achieve the connection between supply and demand, and the medical insurance service for seriously ill and seriously ill people is difficult to meet the actual needs of the elderly with economic difficulties and chronic diseases for a long time. As a result, the life care and medical treatment for the disabled elderly have been a problem to be solved. With the development of Internet of Things, big data, artificial intelligence and other technologies
