IHE提供了一整套用于解决医疗信息系统间互操作问题的解决方案,且通过IHE测试活动验证厂商的系统是否正确实现IHE技术框架.经IHE测试实践发现,多个厂商的医疗信息系统间基于中文的互操作存在一定困难.本文通过分析IHE所依赖的DICOM和HL7两项标准中的相关要求,发现二者对中文编码字符集的规定不一致,而IHE技术框架中又没有相关的补充规定, 这是导致中文互操作存在问题的主要原因;再通过对比DICOM与HL7的中文字符编码规定,建议采用两个标准均支持的编码字符集GB 18030-2000和 ISO-IR-192作为IHE的中文编码字符集,并将其作为中文本地化扩展增补入IHE技术框架. 相似文献

We are in the midst of major changes in our discipline. New technologies and regulations, are poised to fundamentally change the way that pathologists interact with and utilize data. Nowhere is this more apparent than in the realm of anatomic pathology (AP) quality assurance (QA). QA efforts in the AP laboratory today are often limited by the batched assembly line-like nature of the workflow and data trapped within rigid laboratory information systems (LIS). Middleware with progressive business intelligence platforms have helped close this gap by automatically extracting LIS data, and making it easier to manipulate and combine with data from other information systems. Employing informatics tools such as tracking systems in the AP lab minimizes human involvement in repetitive processes which in turn drives down errors, standardizes processes and drives workflow. Scanning barcodes directly inputs data into the LIS which is available for real-time QA monitoring. The use of synoptic reporting, computerized provider order entry (CPOE), and newer technologies such as whole slide imaging also help improve quality in AP. This article reviews current issues and future trends related to AP initiatives in the preanalytic, analytic, and postanalytic phases of laboratory testing. Special emphasis is placed on new technologies that are poised to disrupt the practice of AP in the near future. 相似文献

The demands for information retrieval, processing, and synthesis placed on all providers of health care have increased dramatically in the last several decades. Although systems have been developed to capture charge-related data in support of cost reimbursement, there has been a conspicuous lack of attention paid to information tools to directly enhance the delivery of patient care. The termination of cost reimbursement, together with an increasing recognition of the problems inherent in current manual record-keeping systems, is creating a significant new focus on medical information. This change in focus requires a shift in systems orientation away from financial and departmentally centered systems and toward patient-centered approaches. There is thus increasing recognition of the need for a physician-level medical information specialist to serve as an institution's chief information officer, assuming responsibility for the collection, manipulation, and availability of all patient care-related data. By virtue of training, typical experience, hospital presence, and a noncompetitive position with the hospital's medical staff, the pathologist is uniquely suited for this position. To effectively perform this role, a variety of new specialized data management tools are becoming available. Integrated information systems, patient care management by exception, decision support tools, and, in the future, "artificial intelligence" assists can all be expected to become staples of pathology practice, especially impacting those pathologists who choose to be responsive to the new practice milieu of medical information science. 相似文献

In Japan, the application of LAS/LIS was started in some hospitals in the 1970's. Thereafter, these systems rapidly developed, becoming established in new national medical university hospitals in the late 1970's, referring to the system introduced in the central laboratory of each hospital. Currently, the LAS/LIS application system is employed in the central laboratory. In addition, this system provides diagnostic information based on laboratory data, responds to various questions regarding clinical examinations, develops strategies for controlling hospital infection using the infection control system, and provides information on the appropriate use of antimicrobial agents. In the future, this system may become even more useful. In this study, we reviewed the current status and issues of the mutual utilization of medical information among medical institutions to achieve further advances. 相似文献

Recently, the digital imaging and communications in medicine (DICOM) standard introduced rules for the encoding, transmission,
and storage of the imaging diagnostic report. This medical document can be stored and communicated with the images in picture
archiving and communication system (PACS). It is a structured document that contains text with links to other data such as
images, waveforms, and spatial or temporal coordinates. Its structure, along with its wide use of coded information, enables
the semantic understanding of the data that is essential for the Electronic Healthcare Record deployment. In this article,
we present DICOM Structured Report (SR) and discuss its benefits. We show how SR enables efficient radiology workflow, improves
patient care, optimizes reimbursement, and enhances the radiology ergonomic working conditions. As structured input significantly
alters the interpretation process, understanding all its benefits is necessary to support the change.

Medical knowledge has been increasing and diversifying on a worldwide scale, while specialization of physicians has been extended vigorously. The knowledge has extended beyond the memory of human beings, there by causing the deterioration of service, called "Knowledge crisis". To tackle this problem, the electronic medical textbook(EMT) has been conceived and set up as a medical knowledge base for physician to optimize their specialties and activities in clinical practice. The doctors' diagnostic process is to be mentioned as the solution of backward problem, to speculate problem such as disease by the information observed from symptoms and findings. The EMT is more powerful tool for diagnosis than experiences or textbook that will aid for specifying the name of disease by arranging and combining information. Meanwhile, laboratory information systems are widely introduced. However, there are few systems which allow interpretation of the findings obtained. With this in mind, we have improved the utility of the EMT by enhancing its function with laboratory information follow-up, thesaurus back-up, Japanese language support, and on-line access. It made use of these experiences, we compiled an clinical laboratory handbook "Kensa Koujien", and developed retrieval system. 相似文献

The current curriculum reform is directed toward improvement of students' ability of clinical practice in primary care, and a substantial system of bedside learning is being extensively explored. Introduction of clinical clerkship necessarily forces qualitative changes in the teaching of basic medical sciences. A large number of Japanese medical schools is now attempting to establish a new educational system that makes it possible to change from "didactic education" by lectures and laboratory studies to "self learning education" by means of tutorials and other systems. In this context, Japanese anatomists are urgently requested to develop new and effective clinically oriented educational systems in teaching gross anatomy as a shift from the traditional teaching as a science of morphology. Evaluation of faculty staff's teaching achievement is about to start in many medical schools. Research activities can be evaluated quantitatively. In contrast, measurement of educational activities of faculty staff is very difficult, and all medical schools are devoted to construct effective and liable systems. Anatomy faculty is obliged to devote more time than that of other disciplines in education-related activities such as cadaver collection and associated business. How to evaluate adequately these invisible activities is an issue to be solved before the introduction of a self assessment system. Successful solutions to these issues are critical for production of future anatomists. 相似文献

The Japanese health insurance system has been praised because of the comprehensive coverage of medical costs. The long lifespan of Japanese, the longest in the world, however, because economic conditions are getting worse and medical costs are increasing with the increase of aged people in Japan, the health insurance system is under pressure. The Japanese government is going to start to reduce costs of medical care by applying a system like the DRG/PPS system in the USA, called Diagnosis Procedure Combination(DPC), next year in university hospitals. Under the DPC system, laboratory tests will be non-profit. We have to change the management style of clinical laboratories to cut costs for tests and labor as much as possible, choose tests selectively, respond rapidly to clinical needs, and utilize information technology efficiently for processing of laboratory data. Therefore, corresponding to changes in the medical care system, laboratory medicine has been changing. Commercial clinical laboratories are expanding their pressure in hospitals, and in-hospital laboratories are having a very hard time coping with the pressure. Since laboratory medicine is an essential part of clinical practice, we do not have to be antagonistic. 相似文献

The Digital Imaging and Communications in Medicine (DICOM) is the standard for encoding and communicating medical imaging information. It is used in radiology as well as in many other imaging domains such as ophthalmology, dentistry, and pathology. DICOM information objects are used to encode medical images or information about the images. Their usage outside of the imaging department is increasing, especially with the sharing of medical images within Electronic Health Record systems. However, learning DICOM is long and difficult because it defines and uses many specific abstract concepts that relate to each other. In this paper, we present an approach, based on problem solving, for teaching DICOM as part of a graduate course on healthcare information. The proposed approach allows students with diversified background and no software development experience to grasp a large breadth of knowledge in a very short time. 相似文献

Digital imaging and electronic patient records in pathology using an integrated department information system with PACS 总被引:1,自引:0,他引:1
Picture archiving and communication systems have been widely used in radiology thus far. Owing to the progress made in digital photo technology, their use in medicine opens up further opportunities. In the field of pathology, digital imaging offers new possiblities for the documentation of macroscopic and microscopic findings. Digital imaging has the advantage that the data is permanently and readily available, independent of conventional archives. In the past, PACS was a separate entity. Meanwhile, however, PACS has been integrated in DIS, the department information system, which was also run separately in former times. The combination of these two systems makes the administration of patient data, findings and images easier. Moreover, thanks to the introduction of special communication standards, a data exchange between different department information systems and hospital information systems (HIS) is possible. This provides the basis for a communication platform in medicine, constituting an electronic patient record (EPR) that permits an interdisciplinary treatment of patients by providing data of findings and images from clinics treating the same patient. As the pathologic diagnosis represents a central and often therapy-determining component, it is of utmost importance to add pathologic diagnoses to the EPR. Furthermore, the pathologist's work is considerably facilitated when he is able to retrieve additional data from the patient file. In this article, we describe our experience gained with the combined PACS and DIS systems recently installed at the Department of Pathology, University of Magdeburg. Moreover, we evaluate the current situation and future prospects for PACS in pathology. 相似文献

The ISO/IEEE 11073 standard for Personal Health Devices (X73PHD) aims to ensure interoperability between Personal Health Devices and aggregators—e.g. health appliances, routers—in ambulatory setups. The Integrating the Healthcare Enterprise (IHE) initiative promotes the coordinated use of different standards in healthcare systems (e.g. Personal/Electronic Health Records, alert managers, Clinical Decision Support Systems) by defining profiles intended for medical use cases. X73PHD provides a robust syntactic model and a comprehensive terminology, but it places limited emphasis on security and on interoperability with IHE-compliant systems and frameworks. However, the implementation of eHealth/mHealth applications in environments such as health and fitness monitoring, independent living and disease management (i.e. the X73PHD domains) increasingly requires features such as secure connections to mobile aggregators—e.g. smartphones, tablets—, the sharing of devices among different users with privacy, and interoperability with certain IHE-compliant healthcare systems. This work proposes a comprehensive IHE-based X73PHD extension consisting of additive layers adapted to different eHealth/mHealth applications, after having analyzed the features of X73PHD (especially its built-in security), IHE profiles related with these applications and other research works. Both the new features proposed for each layer and the procedures to support them have been carefully chosen to minimize the impact on X73PHD, on its architecture (in terms of delays and overhead) and on its framework. Such implications are thoroughly analyzed in this paper. As a result, an extended model of X73PHD is proposed, preserving its essential features while extending them with added value. 相似文献

Responding to the challenge for efficient and high quality health care, the shared care paradigm must be established in health. In that context, information systems such as electronic patient records (EPR) have to meet this paradigm supporting communication and interoperation between the health care establishments (HCE) and health professionals (HP) involved. Due to the sensitivity of personal medical information, this co-operation must be provided in a trustworthy way. To enable different views of HCE and HP ranging from management, doctors, nurses up to systems administrators and IT professionals, a set of models for analysis, design and implementation of secure distributed EPR has been developed and introduced. The approach is based on the popular UML methodology and the component paradigm for open, interoperable systems. Easy to use tool kits deal with both application security services and communication security services but also with the security infrastructure needed. Regarding the requirements for distributed multi-user EPRs, modelling and implementation of policy agreements, authorisation and access control are especially considered. Current developments for a security infrastructure in health care based on cryptographic algorithms as health professional cards (HPC), security services employing digital signatures, and health-related TTP services are discussed. CEN and ISO initiatives for health informatics standards in the context of secure and communicable EPR are especially mentioned. 相似文献

The use of a Laboratory Information System (LIS) and Laboratory Automation System (LAS) are clearly superior to manual results in terms of completeness and legibility. As the current clinical information system (CIS) in Gifu University Hospital consists of a complete electronic medical record system, the clinical laboratory was re-engineered to simplify workflow, pay attention to quality assurance, and decrease various costs by an intelligent laboratory management system. We named the new system Gifu Premiotic Intelligent Laboratory System (GPILS). Further advances will concentrate on the cost-effective use of LIS, and the potential use of GPILS in our laboratories will be discussed. In addition, because one of our clinical laboratories currently provides various useful clinical laboratory-oriented information to physicians and patients, we have developed new tools named the "Reference Data Base (RefDB)". In the near future, several different types of computer technology for various clinical laboratory information will lead to the development of highly specific platforms for LIS corresponding to a complete electronic medical record system. 相似文献

The aim of the study was to determine structural modules of laboratory information system (LIS) for the application of new biomedical and information technologies by utilizing current organizational trends. The method used included definition of structural modules according to significant LIS properties, e.g., a large number of data, automation of analyses and rapid exchange of information, and according to the process of information establishment the collection, organization, selection, synthesis and distribution. Thus, outdated distributed software at the Clinical Institute of Laboratory Diagnosis has now been replaced by modular organization. Modules have been developed for the following: data input, online operation of laboratory instruments, preparation of results, compilation of medical documentation on quality assurance based on the application of quality standards, management of finances, and for point of care testing. The method of re-engineering as well as adherence to EN and ISO quality standards were utilized in planning the development of LIS based on the application of new information technologies and in shaping business processes. The application of re-engineering in LIS development results in quality improvement, reduces the cost and time necessary for performance of procedures, and improves relations in organizational structure. 相似文献
