At present, China's medical informatization construction is being promoted throughout the country with the strong support of the government and the promotion of capital. However, in practice, it faces many problems such as insufficient investment in hospital funds, lack of unified standards, lack of necessary technical talents and technical support. The former Ministry of Health had required hospitals at all levels to use information technology for 3 to 5% of total income each year, but up to 48% of hospitals accounted for less than 0.5% of total hospital revenue in information technology. According to a survey, lack of financial support is an important obstacle to the hospital's informatization construction. In addition, due to the lack of uniform standards, a large number of “information islands” are formed between different medical institutions, between hospitals, and between different business systems, resulting in the inability to share resources. Even the hospital's clinical management information system (CIS) image archiving and transmission system (PACS), radiology information system (RIS), inspection information system (LIS), pathological information system (PIS), surgical information system (ORIS), etc. Integration and integration between multiple subsystems is also urgently needed.

In order to achieve the interconnection of medical information, the following five issues need to be resolved.

The first is the establishment and unification of design standards.

As early as 1977, the United States identified the M (MATLAB) language as the standard language for medical industry programming, which is the third national standard language in the United States. Due to the complexity and particularity of the data relationship in the medical industry, once the M language was established, it was quickly used in the medical industry on a large scale. Thanks to the establishment of standards, the medical informationization construction in the United States was achieved today. Development achievements. In contrast, China's medical information software in terms of language standards, C / S (Client / Server, client / server) and B / S (Browser / Server, browser / server) both structures are used, and The interconnection of these two structures is more complicated from the perspective of the prior art. Perhaps with the maturity and popularity of the html5 technology, the two can be interoperable. But for hospitals, spending will increase dramatically. In addition, from the perspective of input cost, B/S structure software generally has only initial one-time input cost and low maintenance cost. For large hospitals, it is beneficial to control software projects and avoid IT black holes, while C/S structure software. The difference is that with the continuous expansion of the scope of application, investment will continue, and the vast majority of medical information companies in China use C/S structure software.

Second, the third-party independent review body is missing.

For example, HIMSS (Healthcare Information and Management Systems Society) is an independent, non-profit NGO (Non-Governmental Organization). The domestic medical informatization system still lacks a fair and trustworthy third-party independent organization. At present, only the Hospital Management Research Institute of the Ministry of Health evaluates the hospital electronic medical record system. However, due to many reasons such as the system, the results of the review are not recognized by many medical institutions. This is precisely the confirmation of Wang Shan, the president of Peking University People's Hospital, that “the hospital is looking for an evaluation system that is recognized internationally in the information construction, which really helps the hospital's informationization.”
