In this paper, we develop an electronic health record (EHR) exchange system based on HL7/CDA standard by using web services. The clinical document architecture (CDA) provides a medical document standard which be used for medical information exchange. The CDA adopts XML to clearly define complete medical objects which include texts, images, voices and other multimedia medical record information. In this research, we leverage the technology of distributed object to make EHR exchange system more general and extensive. We also introduce the technology of web services to make HTTP protocol more efficient in a distributed environment and improve the restriction and defect of current closed medical information system. |
