Health Information Exchange Based on Cloud Computing System

Abstract

Successful publication of the eHealth registry helps improve patient safety and quality of care, but this requires a prerequisite for the interoperability of health information exchange in different hospitals. The clinical documentation structure (CDA) developed by HL7 is a fundamental standard in the document to ensure interoperability, and the deployment of such documentation is essential for interoperability. Unfortunately, hospitals are reluctant to adopt the interoperable HIS system due to the cost of their deployment, with the exception of a few countries. A problem arises even when more hospitals start using the CDA document format because the data scattered in different documents is difficult to administer. In this document, half of the CDA service and the integration of our CDA creation documents are based on cloud computing, which allows hospitals to create CDA documents conveniently without the need to purchase special software. The CDA document integration system integrates multiple CDA documents per patient into a single CDA document and clinicians and patients can examine the clinical data in chronological order. Our system supports the generation and documentation of CDA documents in cloud computing and the service is provided in the open API. Therefore, developers who use different platforms can use the system system to improve interoperability.
