The focus in healthcare has been changed from isolated procedures in a single healthcare institution to the patient-oriented care process spreading over institutional boundaries. So interest shifts from hospital information systems (HIS) to regional health information systems (rHIS). More than with HIS an rHIS needs systematic information management. We present the 3LGM/sup 2/ meta-model and the corresponding 3LGM/sup 2/ tool to support information managers in health care regions. Every sequence of enterprise function, i.e. an information process, needs certain communication paths between those application components supporting the functions. The search for appropriate communication paths within a rHIS model is interpreted as all-pairs shortest-paths problem which is solved using the Floyd- Warshall algorithm. Method and tool has been applied successfully in the setting of the SAXTELEMED project in Saxony, Germany.

Ubiquity has been a key element to modern medical diagnosis system to improve medical service's efficiency and convenience on both medical personals and patients sides. Mobile agents and SIP technology make this anticipation possible. This paper proposes an approach to a ubiquitous medical diagnosis assistant system based on SIP, mobile agents and policy driven technology. First we describe mobile agent and SIP technology, and how they can integrate together at diagnosis assistant system. Second, we present a conceptual model for this medical diagnosis assistant system. Finally, a typical application scenario on diabetes management is described.

This paper sets out a solution for providing physicians and nurses with access to a number of health care information systems whilst mobile in two clinical settings. Firstly supporting physicians whilst mobile within a hospital, and secondly whilst external to the hospital environment. This provides physicians with ubiquitous mobility in clinical healthcare. We first present results of our mobile health care solution that provided hospital professionals with access to patient data using a personal digital assistant (PDA) over a wireless local area network. We then extend our experiences of the eHospital solution together with several other projects that combine the use of a PDA over a GSM/CDMA mobile network for real-time access to information systems. By extending our experiences, we present our proven reference architecture for a secure enterprise mobile healthcare solution for hospital physicians and nurses. The solution furnishes access to several medical information systems whilst supporting a capability to roam within and outside the hospital environment. We accomplish this with seamless roaming between the 802.11 and GSM/CDMA mobile networks.

An escalating global interest in traditional Chinese acupuncture (TCA) demands easy use and reuse of the medical knowledge associated with TCA points, which in turn require appropriate knowledge representation of TCA. A proper knowledge representation generally involves enumeration of conceptual symbols and arrangement of these symbols into some meaningful structure. This study uses the unified medical language system (UMLS) as the source of conceptual symbols and proposes a terminology model as the structure to arrange terms. The purpose is to systematically capture and represent appropriate TCA knowledge in practice. The initial terminology model is refined in an iterative process. The resulting terminology model captures and represents key aspects of TCA knowledge through properly designed model attributes and relations.

Countries across this world are taking many and varied approaches to incorporating information and communications technologies into their health care systems. Accordingly, a great deal can be learned from each other, despite notable differences in such widely variable factors as geography, population density, culture, and nature of health care provision. This paper discusses differences and similarities in health information challenges in China and Canada, focuses on the electronic health record as the core component of the health infostructure, briefly highlights Canadian activities to date and concludes with considerations around potential key learnings for China.

PARADIGMA is a pilot project which aims to develop and demonstrate an Internet based reference framework to share scientific resources and findings in the treatment of major diseases. PARADIGMA defines and disseminates a common methodology and optimised protocols (clinical pathways) to support service functions directed to patients and individuals on matters like prevention, post-hospitalisation support and awareness.

There is increasing worldwide awareness that bionics and artificial intelligence will play an important role in microbial analysis. An intelligent data-warehouse system consisting of an odour generation mechanism, rapid volatile delivery and recovery system, and a classifier system based on neural networks and genetic algorithms have been applied as part of a microbial analysis. The microbiological warehouse environment has, also adopted the concept of fusion of multiple classifiers dedicated to specific feature parameters. The experimental results confirm the soundness of the presented methods.

It is generally accepted that digitized hospital is of great significance in reducing medical errors, improving the quality of medical care and service, and lowering the costs. In recent years, most of the 17 thousands hospitals in China have made arduous and continuous efforts in establishing hospital information systems, however, the outcome is not promising, even in the developed countries, the result of their practice in such efforts is not satisfied. In this paper, we proposed a new method for establishment of digital hospital, with emphasis on the integration of the regional health resources, such as human resources, advanced information technologies, funds, experiences, project management, etc. This approach consists of three main points, first, sharing the regional human resources and standardization of the professional requirements and technical design; second, adopting the "first experimentation and then promotion" strategy and efficiently utilizing public health resources; third, researching and exploring the advanced methods of project management of the health information system and sharing positive as well as negative experiences. We believed these suggestions among others are useful for efficient establishment of digital hospital in the future.

Personalized information retrieval and access is critical to applications in the medical and healthcare domain where the accuracy of the retrieved information and obtaining it in a time critical situation are extremely important. Existing personalized information retrieval and access approaches in the medical and healthcare domain have improved in the last decade, but the centralized system design principle is impeding their ability to be flexible and adaptive to changing demands. These demands arise from the environment in which the approaches are used and from changing user requirements. In this paper we present our preliminary ideas regarding a new component-based design philosophy for personalized information retrieval and access services. We believe this paper offers a new way of thinking about the retrieval of time critical, personalized information from medical information systems.

Vancomycin can induce potent adverse side effects if drug concentration is not controlled within a narrow safety range. Therefore, therapeutic drug monitoring (TDM) is followed to adjust dose and help monitor treatment effects. Because TDM are not helpful in patients taking vancomycin for the first time, it's usage has a limitation to ensure medication safety. This study aimed at using decision tree induction to predict outcomes of vancomycin. Research results demonstrate that the asymmetric distribution among classes in the TDM data would result in prediction deviation. An ideal model with good prediction efficacy could be established by adjusting the ratio among outcome classes through "over-sampling for expanding minority data". The prediction model would be helpful in controlling the positive and negative effects of vancomycin treatment, improving care at the patient level and improving costs at the social level. Some interesting decision rules derived from the decision tree were analyzed its clinical meanings. Precious prescription knowledge is thus extracted and accumulated.
