80% hospitals in China have implemented management information systems. The core of medical and health informatization construction is to realize information sharing between patients and medical institutions, between hospital departments, between hospitals and communities, and between medical insurance departments and health administrative departments. Therefore, experts believe that the current tasks of China's medical and health information construction mainly include promoting the construction of hospital information network, actively developing telemedicine for cities and remote areas, forming a unified national medical information network, introducing feasible medical insurance transfer and connection schemes as soon as possible, realizing cross-regional settlement of medical treatment in different places, and promoting the construction of regional health information platforms.
