China's digital medical construction has just begun, has built the hospital information system, mostly close to the general sense of enterprise and public institutions management information system, and the most important feature of digital health care, is to account for 80% of the total amount of information in the hospital's business information technology of the clinical information, and medical image archiving and communication system (PACS) to be the core technical support, so that the digital health care has great medical value. In this way, digitalized healthcare has great medical value. However, for a long time, people's awareness of digital health care is not enough, coupled with the technical limitations of the real-time process, hindering the extent of its implementation in China. The country's existing 16,000 medical institutions digitization system of less than 1/3 of the hospital scale, the real complete even less.
Survey studies have concluded that standardization is an important factor hindering the current development of digital health care in China. In the current operation of the HIS product non-standardized communication interface problem is serious, developers and hospitals in the construction of HIS without reference to the appropriate international standards (HL7), focusing only on a single PACS and the success of HIS operation, but not for the later PACS and HIS to leave open interfaces, resulting in the current system is very difficult to later systems to connect to the system, and the interconnection between these systems itself is very difficult. The interconnection between these systems is difficult. The lack of standards for hospital business processes and the lack of standards for *** enjoyment of data have resulted in a large number of low-level duplication of HIS development, making it difficult to transplant and promote, and making it difficult to *** enjoyment of data, which are potentially harmful to the further development of digital healthcare.
