An Approach To Transmit And Transact HL7 Documents In Network

Objective: Nowadays, sharing and exchanging medical information be an insistent demand. Yet domestic have not a standard to follow. HL7, an accepted by international medical environment electronic information exchange standard, is a good choice. However, it also has some different with our situation that needs localization when it applied. In addition, most HIS is lacking of the ability to exchange and transact the medical message in Internet. The method that implement exchange of the HL7 documents where not change the frame of current system, has important practical sense. Whereas we have researched the method how to transmit and transact the HL7 documents.Methods: The research used the laboratory information as research object to design a demo of HL7 documents transmit and transact system. The system implements HL7 localization rebuilding includes HL7 setting, corresponding, and conversion of laboratory information. In addition, it parses and constructs HL7 documents through a gateway. We programmed the demo by Visual Basic; used HTTP as transmit protocol; applied SOAP to achieve remote procedure call.Conclusions: The run of system indicates that gateway mode is a doable and convenient technique to introduce HL7 to HIS. Test also show that system can transmit HL7 documents that encoded by standard encoding rules and XML encoding rules in network normally. It is easily to implement network exchange of medical information. In addition, the system achieves HL7 localization rebuilding of laboratory information. Applied this research into fact, can fulfill the need of medical information sharing today. So can say, the research has practicable value.
