Distributed Electronic Health Record System Based On Middleware

With the rapid development of information technology, traditional health care is evolving to a more digital and electronic stage. The Electronic Health Record (EHR) is a patient’s basic information and health care related information conforming to the standard. It is not only able to provide useful information to medical workers, but also exchange resources with other information systems. However, with the growing complexity of electronic health record data sources, it becomes a significant challenge to set up a structure which allows different types of data sharing and exchanging in multi-platform applications. It is even more important to discover a method to support a large number of users from different application platforms in relation to sharing and exchanging data at the same time.In this paper, we have proposed a distributed electronic health record system based on middleware to address the problem. Both permanent and real-time data should pass through the middleware provided by the system, and will be transformed into standard format for storage. Multi-thread and distributed server group design will allow the system to be more flexible and scalable, and will be able to provide services to users concurrently.The system creates a standard data format for data transferring and storage. All raw data collected from different kinds of sensor systems will be formatted by means of an application programming interface (API) or software development kit (SDK) system provided before up-loading to the system. Encryption methods are also implemented to ensure data security and privacy protection.
