Development and pilot trial of a web-based job placement information network.

The purpose of this project was to develop and pilot a web-based job placement information network aiming at enhancing the work trial and job placement opportunities of people with disabilities (PWD). Efficient uses of information technology in vocational rehabilitation were suggested to help improve PWD employment opportunities and thus enable them to contribute as responsible citizens to the society. In this preliminary study, a web-based employer network was so developed to explore Hong Kong employers' needs and intentions in employing PWD. The results indicated that Hong Kong employers generally agreed to arrange work trials for PWD whose work abilities match job requirements. They also expressed that they would offer permanent job placements to those PWD who showed satisfactory performance in work trials. The present study evidenced that using an information network could expedite communications between employers and job placement services, and thus job placement service outcomes. It is hoped that a job placement databank could thus be developed through accumulating responses from potential employers.

Formation of an information network in a self-pulsating multimode laser.

We investigated self-induced pulsations in a globally-coupled microchip multimode solid-state laser operating on a Lambda transition. A variety of dynamic states, featuring locking of pulsation frequencies, multidimensional quasiperiodic, and chaotic pulsations, induced by nonlinear modal interactions were observed depending on the number of oscillating modes. The underlying modal interplay was characterized in terms of the dynamic statistical quantity of information circulations. Mode grouping and information sender-receiver-mediator relationships established among mode groups, i.e., "information networks," were identified. Observed dynamic states were reproduced by numerical simulation of a model equation and each dynamic state was shown to create its own information network.

Adoption of security and confidentiality features in an operational community health information network: the Comox Valley experience--case example.

Since 1993, a budding community health information network (CHIN) has been in operation in the Comox Valley in Canada. A general hospital and three multi-doctor clinics are linked electronically. The clinics operate without paper charts using a comprehensive clinic information system. The link is provided by RSALink, a commercial message exchange service, based on Health Link, a system developed at the University of Victoria (McDaniel et al., Can. Med. Inform. 1 (1994) 40-41; McDaniel, Dissertation, University of Victoria, Canada, 1994). Health Link is a highly adaptable message exchange service with rich functionality. Despite this, the system is used exclusively to receive laboratory results transmitted by the hospital's laboratory system (RSAStat). The results are deposited in the patient data base of a commercial clinic information system (CliniCare). This case is instructive because the users' selection of services available through Health Link allows us to observe the preferences in this informational sophisticated environment. Laboratory data transmission is appreciated as highly beneficial. The reliability, security and ample privacy protection and authentication features of Health Link, in contrast, are used in a black box mode and are not consciously exploited. This is consistent with our experience of the use of other systems which have operated for a substantial time, essentially without serious protection features. Our experience suggests that security and confidentiality features are exploited only to the extent that they do not require additional effort or conscientious intervention. This puts the system provider in the difficult position of either offering interactive systems that nobody will use, or providing automated features that nobody is aware of and that are therefore not used to full advantage--if at all.

Health information networks: enabling care management in IDSs.

To be successful, IDSs require streamlined, information integration across the continuum of care. Having this capability enables IDSs to manage care and costs efficiently, provide physicians with enterprisewide access to eligibility information, and respond to the communication and quality demands of patients. For most IDSs, the quickest and most cost-effective way to achieve overall information-system integration is to implement a health information network (HIN) based on Internet technologies. A HIN enables IDS providers and staff to access requisite administrative and clinical information from throughout the enterprise using a Web browser.

HYGEIAnet: the integrated regional health information network of Crete.

The healthcare environment is currently changing and the health sector is being transformed to meet new challenges and to benefit from new opportunities. Priorities for the 21st century ought to be set based on emerging dominant trends in healthcare, including the shift towards shared or integrated care, in which an individual's healthcare is the responsibility of a team of professionals across all levels of the healthcare system hierarchy. In addition to the requirement for efficient and secure access to the Integrated Electronic Health Record (I-EHR) of a citizen, this necessitates the development and deployment of Regional Health Information Networks (RHINs), synchronous and asynchronous collaboration services, and novel eHealth and mHealth services, facilitated by intelligent sensors, monitoring devices, hand-held or wearable technologies, the Internet and wireless broadband communications. These further require the adoption of an open Reference Architecture and the creation of a scalable Health Information Infrastructure (HII).This paper discusses the challenges encountered in developing and deploying HYGEIAnet, the Regional Health Information Network of Crete, as well as relevant benefits for citizens and health professionals. Furthermore, HYGEIAnet systems and services are presented, with emphasis on the development of the HII and the implementation of the I-EHR service for providing secure, role-based access to validated content by authorized and authenticated users.

Occupational rubber glove allergy: results of the Information Network of Departments of Dermatology (IVDK), 1995-2001.

About 21% of the patients with occupational contact dermatitis registered in the Information Network of Departments of Dermatology (IVDK) in the years 1995-2001 were patch tested due to suspected rubber glove allergy. We analysed reaction frequencies to thiurams, dithiocarbamates, mercaptobenzothiazole (MBT) and its derivatives, thioureas, and 1,3-diphenylguanidine (1,3-DPG). Thiurams were by far the most frequent rubber allergens in these patients (16.2% positive reactions, age- and sex-standardized), and the reaction frequency showed a decline from 20.9% in 1997 to 12.8% in 2000. However, this trend was not statistically significant, and was followed by an increase to 16.5% in 2001. All other rubber allergens showed no time trend at all. Although, according to manufacturers' information, the use of dithiocarbamates and MBT derivatives in rubber glove production increased in recent years, these allergens elicited positive reactions in only about 3% of the patients tested, and showed no increasing trend. Thioureas and 1,3-DPG are not widely used in rubber glove production, and play only a minor role in rubber glove contact allergy. Most of the positive reactions to 1,3-DPG are probably false-positive, irritant reactions.

An open, component-based information infrastructure for integrated health information networks.

A fundamental requirement for achieving continuity of care is the seamless sharing of multimedia clinical information. Different technological approaches can be adopted for enabling the communication and sharing of health record segments. In the context of the emerging global information society, the creation of and access to the integrated electronic health record (I-EHR) of a citizen has been assigned high priority in many countries. This requirement is complementary to an overall requirement for the creation of a health information infrastructure (HII) to support the provision of a variety of health telematics and e-health services. In developing a regional or national HII, the components or building blocks that make up the overall information system ought to be defined and an appropriate component architecture specified. This paper discusses current international priorities and trends in developing the HII. It presents technological challenges and alternative approaches towards the creation of an I-EHR, being the aggregation of health data created during all interactions of an individual with the healthcare system. It also presents results from an ongoing Research and Development (R&D) effort towards the implementation of the HII in HYGEIAnet, the regional health information network of Crete, Greece, using a component-based software engineering approach. Critical design decisions and related trade-offs, involved in the process of component specification and development, are also discussed and the current state of development of an I-EHR service is presented. Finally, Human Computer Interaction (HCI) and security issues, which are important for the deployment and use of any I-EHR service, are considered.

Tufts academic health information network: concept and scenario.

Tufts University School of Medicine's new health sciences education building, the Arthur M. Sackler Center for Health Communications, will house a modern medical library and computer center, classrooms, auditoria, and media facilities. The building will also serve as the center for an information and communication network linking the medical school and adjacent New England Medical Center, Tufts' primary teaching hospital, with Tufts Associated Teaching Hospitals throughout New England. Ultimately, the Tufts network will join other gateway networks, information resource facilities, health care institutions, and medical schools throughout the world. The center and the network are intended to facilitate and improve the education of health professionals, the delivery of health care to patients, the conduct of research, and the implementation of administrative management approaches that should provide more efficient utilization of resources and save dollars. A model and scenario show how health care delivery and health care education are integrated through better use of information transfer technologies by health information specialists, practitioners, and educators.

Design of a patient-centered, multi-institutional healthcare information network using peer-to-peer communication in a highly distributed architecture.

OBJECTIVE: to design a community healthcare information network for all 450,000 citizen in the State of Geneva, Switzerland, connecting public and private healthcare professionals. Requirements include the decentralized storage of information at the source of its production, the creation of a virtual patient record at the time of the consultation, the control by the patient of the access rights to the information, and the interoperability with other similar networks at the national and european level. METHODS: a participative approach and real-world pilot projects are used to design, test and validate key components of the network, including its technical architecture and the strategy for the management of access rights by the patients. RESULTS: a distributed architecture using peer-to-peer communication of information mediators can implement the various requirements while limiting to an absolute minimum the amount of centralized information. Access control can be managed by the patient with the help of a medical information mediator, the physician of trust.

Information network topologies for enhanced local adaptive management.

We examined the principal effects of different information network topologies for local adaptive management of natural resources. We used computerized agents with adaptive decision algorithms with the following three fundamental constraints: (1) Complete understanding of the processes maintaining the natural resource can never be achieved, (2) agents can only learn by experimentation and information sharing, and (3) memory is limited. The agents were given the task to manage a system that had two states: one that provided high utility returns (desired) and one that provided low returns (undesired). In addition, the threshold between the states was close to the optimal return of the desired state. We found that networks of low to moderate link densities significantly increased the resilience of the utility returns. Networks of high link densities contributed to highly synchronized behavior among the agents, which caused occasional large-scale ecological crises between periods of stable and high utility returns. A constructed network involving a small set of experimenting agents was capable of combining high utility returns with high resilience, conforming to theories underlying the concept of adaptive comanagement. We conclude that (1) the ability to manage for resilience (i.e., to stay clear of the threshold leading to the undesired state as well as the ability to re-enter the desired state following a collapse) resides in the network structure and (2) in a coupled social-ecological system, the system-wide state transition occurs not because the ecological system flips into the undesired state, but because managers lose their capacity to reorganize back to the desired state.
