IHE cross-enterprise document sharing for imaging: interoperability testing software.
TL;DR: A software is described that is used to test systems that are involved in sharing medical images within the EHR to test the Cross Enterprise Document Sharing for imaging (XDS-I) integration profile.
Abstract: With the deployments of Electronic Health Records (EHR), interoperability testing in healthcare is becoming crucial. EHR enables access to prior diagnostic information in order to assist in health decisions. It is a virtual system that results from the cooperation of several heterogeneous distributed systems. Interoperability between peers is therefore essential. Achieving interoperability requires various types of testing. Implementations need to be tested using software that simulates communication partners, and that provides test data and test plans. In this paper we describe a software that is used to test systems that are involved in sharing medical images within the EHR. Our software is used as part of the Integrating the Healthcare Enterprise (IHE) testing process to test the Cross Enterprise Document Sharing for imaging (XDS-I) integration profile. We describe its architecture and functionalities; we also expose the challenges encountered and discuss the elected design solutions. EHR is being deployed in several countries. The EHR infrastructure will be continuously evolving to embrace advances in the information technology domain. Our software is built on a web framework to allow for an easy evolution with web technology. The testing software is publicly available; it can be used by system implementers to test their implementations. It can also be used by site integrators to verify and test the interoperability of systems, or by developers to understand specifications ambiguities, or to resolve implementations difficulties.

TL;DR: This Digital Imaging And Communications In Medicine tends to be the representative book in this website.
Abstract: Spend your few moment to read a book even only few pages. Reading book is not obligation and force for everybody. When you don't want to read, you can get punishment from the publisher. Read a book becomes a choice of your different characteristics. Many people with reading habit will always be enjoyable to read, or on the contrary. For some reasons, this Digital Imaging And Communications In Medicine tends to be the representative book in this website.

TL;DR: A toolkit to support federating multiple image data resources such that clients can interact with them as if they are stored in a centralized PACS, and makes it easy to use existing DICOM client applications for data access.
Abstract: Collaborations in biomedical research and clinical studies require that data, software, and computational resources be shared between geographically distant institutions. In radiology, there is a related issue of sharing remote DICOM data over the Internet. This paper focuses on the problem of federating multiple image data resources such that clients can interact with them as if they are stored in a centralized PACS. We present a toolkit, called VirtualPACS, to support this functionality. Using the toolkit, users can perform standard DICOM operations (query, retrieve, and submit) across distributed image databases. The key features of the toolkit are: (1) VirtualPACS makes it easy to use existing DICOM client applications for data access; (2) it can easily be incorporated into an imaging workflow as a DICOM source; (3) using VirtualPACS, heterogeneous collections of DICOM sources are exposed to clients through a uniform interface and common data model; and (4) DICOM image databases without DICOM messaging can be accessed.

TL;DR: This study proposed a design of an integrated cloud-based e-medical record which uses ICD-10 and HL7, which is based on integrated model of patient medical record information system using health care standard information format for data exchange.
Abstract: This study conducted a research on the implementation of cloud computing in health care organizations, focused on integrated model of patient medical record information system using health care standard information format for data exchange. Health care organizations use variety of IT applications and infrastructures which always need to be updated as a result of rapid growth in health care services. The diversification on how health care organizations maintaining their operations, especially on maintaining patient's medical information resulted the difficulty of accessing patient's data. This study then proposed a design of an integrated cloud-based e-medical record which uses ICD-10 and HL7.

TL;DR: Interoperability impediments in healthcare are analyzed by first defining them and providing concrete healthcare examples, followed by discussion of how specifications can be defined and how verification can be conducted to eliminate those impediments and ensure interoperability in healthcare.
Abstract: Interoperability is a requirement for the successful deployment of Electronic Health Records (EHR). EHR improves the quality of healthcare by enabling access to all relevant information at the diagnostic decision moment, regardless of location. It is a system that results from the cooperation of several heterogeneous distributed subsystems that need to successfully exchange information relative to a specific healthcare process. This paper analyzes interoperability impediments in healthcare by first defining them and providing concrete healthcare examples, followed by discussion of how specifications can be defined and how verification can be conducted to eliminate those impediments and ensure interoperability in healthcare. This paper also analyzes how Integrating the Healthcare Enterprise (IHE) has been successful in enabling interoperability, and identifies some neglected aspects that need attention.

TL;DR: A complete test execution framework for HL7-based systems that provides high-level constructs allowing dynamic set up of test scenarios involving all the layers in the interoperability stack, and the computer-interpretable test description language developed offers a configurable system with pluggable adaptors.
Abstract: Health Level Seven (HL7) is a prominent messaging standard in the eHealth domain, and with HL7 v2, it addresses only the messaging layer. However, HL7 implementations also deal with the other layers of interoperability, namely the business process layer and the communication layer. This need is addressed in HL7 v3 by providing a number of normative transport specification profiles. Furthermore, there are storyboards describing HL7 v3 message choreographies between specific roles in specific events. Having alternative transport protocols and descriptive message choreographies introduces great flexibility in implementing HL7 standards, yet, this brings in the need for test frameworks that can accommodate different protocols and permit the dynamic definition of test scenarios. In this paper, we describe a complete test execution framework for HL7-based systems that provides high-level constructs allowing dynamic set up of test scenarios involving all the layers in the interoperability stack. The computer-interpretable test description language developed offers a configurable system with pluggable adaptors. The Web-based GUIs make it possible to test systems over the Web anytime, anywhere, and with any party willing to do so.

TL;DR: An actor-based testing framework is discussed in detail and an architecture that extends this framework to support testing of integrated healthcare systems using multiple messaging and document data exchange standards is presented.
Abstract: Correct data exchange is critical for ensuring reliable healthcare systems. Standards based systems are the foundation for achieving this goal. However, standards alone are not enough to ensure this promise; conformance and interoperability testing are essential. We present and compare conformance testing strategies for a widely used healthcare clinical data exchange messaging standard. We discuss in detail an actor-based testing framework and give insight on the approach used in developing the framework. We present an architecture that extends this framework to support testing of integrated healthcare systems using multiple messaging and document data exchange standards.
