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 problem arises 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. Key Words: Electronic Health Record, health information exchange, HL7, CDA, cloud computing, SaaS
1.INTRODUCTION The health information that consists health of the patient, health care provided to that patient as well as the reaction of the patient to the provided healthcare can be stored as electronic health information in the form of longitudinal collection, thus forming an Electronic Health Record (EHR) [1]. Therefore, the implementation of HIE system is made to ensure Š 2017, IRJET

successful maintenance of EHR [2]. But there is also a problem of incompatibility between systems and also there are different characteristics involved in HIS [3], [4]. Thus, there is a need to standardize the health information exchange between hospitals ensuring interoperability over health information. Therefore, the core of guaranteeing interoperability is to standardize the clinical document. The major standard for clinical documents is CDA which was established by Health Level Seven (HL7). CDA is the core document standard, an XML document which holds the structure and semantics of clinical documents for health information exchange. The first version of CDA was released on 2001 and it's second version was released on 2005. Many countries have done many successful projects adopting CDA [7], [8], [9]. To improve semantic interoperability, many active works are done based on openEHR and CEN3606 [10], [11]. More HIE system has to support CDA to establish confidence in interoperable Health Information Exchange. Moreover, the structure of CDA is too complex and the correct CDA Document production is difficult without the good understanding of the CDA standard and enough experience with it. Also, the HIS development platforms for hospitals differ so greatly in such a way that generation of CDA documents in every hospital invariably requires a separate CDA generation system. In addition to that, hospitals refuses to adopt a new system unless it is perfectly necessary for delivery of care. As a result, except for only few handful countries like New Zealand or Australia, the adoption rate of EHR is too low [12]. To promote EHR adoption among hospitals, the USA government had implemented an incentive program called the Meaningful Use Program [13]. ISO 9001:2008 Certified Journal
