A New Enhance Secure System For Quality Services In Health Information System On Cloud.

Abstract

Maintenance of Electronic Health Record helps improve patient safety and quality of care, but to do that we need the operation of interoperability between Health Information Exchange at different hospitals. The Clinical Document Architecture (CDA) established by HL7 is a core document standard to ensure such interoperability. Unfortunately, hospitals refuses to adopt interoperable HIS due to its deployment cost. More problems arise when all hospitals start using the CDA document format because the data scattered in many documents are difficult to manage. In this paper, we describe our CDA document generation and integration which is an Open API service based on cloud computing, through which hospitals are enabled to conveniently generate CDA documents without having to purchase 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.
