Resumo: |
In today’s world, information systems are increasingly necessary for organizations to continue to provide their services with quality. These systems have become increasingly heterogeneous and complex. Executing them in an integrated manner with other systems has become a prerequisite. Due to the existence of legacy systems with stored data that needs to be maintained, the integration between systems is impaired. This situation is aggravated when it comes to health information systems because there are specific laws that require that data need to kept for decades. One well-known health information system is the Electronic Health Record (EHR). The EHR system is the electronic record of the patient’s health consisting of information coming from di erent systems. These systems are often developed by di erent companies and use di erent technologies. With this in mind, the use of a Service-Oriented Architecture (SOA) becomes very useful, since it is a solution capable of integrating heterogeneous structures using specific standards such as web services. However, designing SOA-based systems is not a trivial task. A robust and well-defined architecture is crucial to the success of applications based on SOA paradigm. Therefore, this study aimed to present a software architecture for the development of an EHR system based on SOA considering interoperability between legacy systems. Thus, a set of research methods were applied. Initially, a literature review was conducted in order to find relevant papers that could help in the development of applications in healthcare. This review was bounded on the studies related to EHR systems. The review of these studies aimed to first build a base of knowledge about problems, di culties and challenges regarding the implementation of EHR systems. The analysis of the literature showed that there was a deficiency in precisely defining a specific architecture for the development of EHR systems.The architecture is used a case study in order to test the applicability of the same. The object of this study was the University Hospital of the Federal University of Sergipe where it was developed an EHR system prototype. The architecture proposed in this work was of fundamental importance to the development of the EHR system prototype. The proposed architecture has enabled communication between the EHR system prototype and applications that mimicked the Legacies systems. Among the limitations of the case study, that were not possible to be used to the real legacy systems to the achievement of architecture tests. Applications were created that simulated real systems. However, these simulations did not a ect the result of the study which showed how to satisfactorily creating a software architecture based on SOA for building an EHR system considering interoperability between legacy system. |
