A successful implementation of an electronic health record can enhance patient safety and the standard of care, but interoperability across hospitals' HIE systems is a need. The spread of this document format is essential for interoperability, and the Clinical Document Architecture (CDA) created by HL7 is a fundamental document standard to assure such compatibility. Sadly, hospitals are hesitant to embrace interoperable HIS because of its adoption costs, with the exception of a small number of nations. As all hospitals switch to the CDA document format, further issues appear since it is challenging to handle the data spread throughout so many papers. In this article, we discuss our cloud-based Open API service for CDA document production and integration, which enables hospitals to quickly produce CDA documents without having to buy software. Our CDA document integration system integrates multiple CDA documents per patient into a single CDA and physicians and patients can browse the clinical data in chronological order. Our system of CDA document generation and integration is based on cloud computing and the service is offered through Open API. Developers using different platforms thus can use our system to enhance interoperability.
