ABSTRACT
In this study, using the HL7 protocol, we developed patient management system gateway which is composed of 2 parts; message transferring-receiving and sentcncc generating-parsing part. To make the gateway more transplantable, it was developed on the PC operated with Windows OS. To make the gateway more productive, it was developed with Visual Basic 6.0. The database was built into MS SQL. Server which is most optimized on MS Windows NT system environment. This gateway system has the advantage of easy data-exchange capability between the patient management systems of medical facility and the messages transferred can he managed systematically and he transplanted easily into PC base hospital information system.

In this study, we developed an order communication system (OCS) gateway, which observe the protocol of HL7 standard and is operated on PC. In the aspect of architecture, the OCS gateway consists of three modules, which are message transmission/reception, data processing, and security. In the aspect of user interface, the OCS gateway consists of two main screens, which are order data management and message transmission. The main function of the OCS gateway is to convert the order records such as pharmacy, observation and diagnostic study, radiology, other diagnostic study, and treatment to a message, which observe the protocol that presented by HL7 standard, and transmit the message to other OCS gateway. To enforce the security of this gateway, we applied a hybrid security method using both Rivest-Shamir-Adleman (RSA) and Data Encryption Standard (DES). With the developed OCS gateway, different OCS systems in the inside and outside of the country can exchange their order data effectively and safely. Because it is developed for PC base Windows operating system, this gateway is more transplantable to the existing hospital information system (HIS) which is constructed on PC.
