Design And Implementation Of A SOA-based Hospital Information Integration Platform

With the development of hospital information construction, the demands for informationintegration and business connectivity become increasingly urgent. Application integration isthe only way to realize the integration of hospital information. And it’s difficult to apply thetraditional application mode to achieve information integration and business connectivity. Infact, an independent manufacturer or company can’t finfish the systematic hospitalinformation integration which can be done with the cooperation among the hospital, thesoftware integration company and the application subsystem manufacturer. The hospitaldoesn’t lead in the systematic information integration and is unwilling to contact severalapplication subsystem manufacturers which is not convenient for the maintenance andreplacement of the subsystems in the future. However, the traditional private contact modebetween the hospital and the application subsystem manufacturers is generalized by moresoftware integration companies. This kind of contact mode can’t keep pace with thedevelopment of hospital informatization in the future. So how to join up these applicationsubsystems to a relatively stable platform in order to realize the data connectivity among thesubsystems becomes a must in the hospital work. If continuously running according to theprevious contact mode, the security, reliability and stability of the hospital information systemwill greatly reduce. Meanwhile, the maintenance cost of the hospital information system willincrease year by year.And if each application message subsystem of the hospital supports this mode, they canmake data switching with other platforms as well as information sharing with their relevantapplication message subsystems. The construction of the hospital information integrationplatform provides the standard and plan for the hospital informatization, also a sharing andutilizing platform for the hospital internal information sharing. Based on the informationintegration platform, the synchron in each clinical application subsystem’s data dictionary canbe achieved. And the department information, user information or patient information will allbe in the coordination through joining in the information integration platform. In addition, itdeals with out-of-sync problems in several information systems and builds up a moreadvanced business application which can make it possible for doctors to provide patients the full information service supports based on clinical sciences. Especially in the circumstancethat exchanging data with the operating departments of the social insurance, commercialinsurance, health authorities(regional health data center), the public health community,healthfile and etc., such a stable,security halfpace for information sharing among variousdepartments is in need.To sum up, in order to adapt the informatization of the hospital to its development aswell as solving the problem, the most fundamental and efficient way is to build up aInformation integration platform.
