Abstract
Electronic – information, this conception is in vogue recently, and many hospitals adhere this trend to switch their material to digital information. This raises their efficiency substantially. Because frameworks of information system in every hospital are different, exchange of data between hospitals, clinical documents is very difficult. This is a waste of patients time and precious medical resources indirectly. Thus, many countries are striving for developing electronic medical record standard.
In light of the need of medical record exchange, we used the HL7/CDA standard to develop our system. CDA is a standard adopted by HL7 that specifies the structure and semantics of clinical documents for the purpose of exchange. The documents are coded in XML and can include multimedia data (like image, sound…).
Information system in hospital is very huge, so it is difficult to change the entire old system for the purpose of exchanging medical record. By cooperating with the E.C.K.(En Chu Kong) Hospital, we design an exchange system parallel to the hospital information system and is responsible for the exchange. By using the Web Service, the proposed system can access with the mother system and obtain up to date circulation of medical data. Besides text, the exchange system provides the medical image so that doctors can obtain more information on patients' condition. Clinical test is conducted for 30 patients and find it is workable.
