The research of health information integration is one of the hot topics in health information systems. Plenty of heterogeneous legacy systems exist in hospitals now due to many reasons. This leads to new problems that the communication among these systems is very difficult. It becomes a challenge for achieving a total-integrated health information system solution. To solve this problem, this paper proposes a health information integration platform based on Service-Oriented Architecture and Web services. An integrated client, which employs the data redirection techniques in operating systems and is called the universal health-information integration component, is developed. A real case study is used to show the design and implementation details as well as the valid integration among the heterogeneous system we have obtained.
