CHDC: Common Hospital Data Connector for exchanging medical information

With the advance of technology, smart healthcare is emerging, and the amount of medical data is exploding. Currently, these large-scale medical data is scattered and stored in a variety of institutions. The data format is also different. These make medical data exchange difficult. Although there are many attempts to integrate EMR systems into a standardized structure, a high rate of EMR adoption in Korea using a standardized model such as HL7 RIM (Reference Information Model), attempts to replace systems that are already in use have largely failed due to a variety of causes, including time, cost and implementation manpower, and so on. In this paper, we propose a Common Hospital Data Connector model that has a way to integrate medical data without replacing the systems. This model defines what data should be extracted from the system with a variety of interfaces. These data profiles are based on statutory document and are able to be accepted in other medical institution. To ensure interoperability, the document is based on the international standard of Fast Healthcare Interoperability Resources and can be created in the form of a statutory document that can be printed. We applied this model to the hospital and verified that it can be used in actual services.
