Transmission of clinical information based on HL7 CDA standard

Abstract

At present, the phenomenon of electronic medical institutions is becoming more and more popular. In order to provide or get better medical services, the demand for exchange and sharing of clinical information is also increasing. However, due to the heterogeneity of the medical system, the problem of data format is not uniform, which has seriously hindered the delivery of clinical information, so that the patient's clinical information can not be fully utilized. In this paper, we apply the information model of HL7 CDA standard to package clinical information documents, use XML language to achieve a simple CDA document and its format output. At the same time, through the JDBC and XML parser to achieve the automatic generation and analysis of CDA documents. By encapsulating the CDA document in the HL7 message, the transmission of clinical information is realized.
