In promoting the "Internet plus contract service", it is proposed to build or improve the family doctor service and management information system based on the regional national health information platform to provide residents with online services such as contract signing, health consultation, chronic disease follow-up and two-way referral. The service behavior recorded by information system is an important index to evaluate the service performance of family doctors. Strengthen the exchange and sharing of regional health information, open up the data channel between family doctor service and management information system, medical institution diagnosis and treatment system and basic public health system, and actively promote the application of new technologies such as artificial intelligence.
