an open component based Information Infrastructure for integrated health Information networks
International Journal of Medical Informatics, 2002Co-Authors: Manolis Tsiknakis, Dimitrios G Katehakis, Stelios C OrphanoudakisAbstract: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.

an open component based Information Infrastructure to support integrated regional healthcare networks
Studies in health technology and informatics, 2001Co-Authors: Dimitrios G Katehakis, Manolis Tsiknakis, Stavros Kostomanolakis, Stelios C OrphanoudakisAbstract:A fundamental requirement for achieving continuity of care is the seamless sharing of multi-clinical Information. Several different technological approaches can be followed to enable the sharing of health record segments. In all cases interoperability between systems is a prerequisite and this requires presently a major technological challenge. Interoperability can be achieved either through messages or through a more advanced approach based on a federation of autonomous systems. Message based integration is centered mainly on the exchange of HL7 and DICOM messages for achieving the functional integration of clinical Information systems (CIS) at institutional or regional level. The federated approach is principally used for facilitating the virtual view of the Integrated Electronic Health Record (I-EHR), without having to replicate unnecessary Information. Within the context of HYGEIAnet, which is the regional health telematics network of Crete, both approaches have been utilized for providing end users with seamless access to clinical Information. Both are based on an open architecture, which provides the framework for the reuse of standardized common components and public interfaces. This work presents the experiences related to the implementation of "messaging" and "federating" in HYGEIAnet, which are used complementary to each other. A comparison of the two parallel approaches, together with their strengths and weaknesses is described, and evaluation is given from the technological as well as the end users' perspective. Emphasis is given on the technological challenges in developing open, component-based Information Infrastructure to support integrated service delivery.

Information Infrastructure for an integrated healthcare services network
IEEE International Conference on Information Technology and Applications in Biomedicine, 2000Co-Authors: Manolis Tsiknakis, Dimitrios G Katehakis, Stelios C OrphanoudakisAbstract:The growing demand for more efficient and effective healthcare services, coupled with an implicit requirement for supporting citizen mobility and continuity of care, is currently setting the stage for the exploitation of Information and communications technologies, also known as Information society technologies, in the healthcare sector. The current vision comprises affordable access to healthcare resources and services for all citizens, thus making medical expertise a shared resource wherever and whenever needed. Important areas in which Information society technologies are likely to have a significant impact include those of pre-hospital health emergencies, remote monitoring of patients with chronic conditions and medical collaboration through sharing of health-related Information resources. Accessibility to these and other media-rich, user-oriented services, in the context of the emerging global Information society, will be supported by a healthcare Information Infrastructure (HII) which can achieve effective horizontal integration of networked Information sources.

innovation of in on Infrastructures articulating the role of architecture in Information Infrastructure evolution
Journal of the Association for Information Systems, 2014Co-Authors: Miria Grisot, Ole Hanseth, Anne Asmyr ThorsengAbstract:In this paper, we address the question: “which conditions enable successful Information Infrastructure innovation?”. Information Infrastructures are characterized by nonlinear evolutionary dynamics. Based on a case study that examines the design, development, and initial use of a web-based solution for patient-hospital communication at a Norwegian hospital over a ten-year period, we trace the evolution of a new II. This longitudinal analysis takes installed base cultivation as its conceptual basis. Specifically, we draw on three aspects of a cultivation strategy: growth process, user mobilization, and learning to cultivate. The analysis shows how the solution started as a bottom-up initiative of a small and motivated team at the hospital IT department, and how it grew gradually in a flexible and evolutionary way. Our findings support the argument that successful Infrastructure innovations are based on a cultivation strategy addressing specific users’ needs, usefulness, and evolutionary growth. We make three key contributions to Information Infrastructure research. First, we expose the role architecture plays in the growth of IIs. Second, we provide insights about cultivating IIs, especially in their bootstrap phase. Third, we identify three different but interrelated types of innovation—in, of, on Infrastructure—that articulate the critical role of IIs architecture in enabling successful innovation.

inscribing behaviour in Information Infrastructure standards
Accounting Management and Information Technologies, 1997Co-Authors: Ole Hanseth, Eric MonteiroAbstract:Abstract This paper focuses on the processes producing the standards which make up the technical back-bone of an Information Infrastructure. These standards are neither ready-made nor neutral. They are currently being developed, and they ‘inscribe’ behaviour in complex and non-transparent ways. We explore how this takes place, identifying by whom, where and how inscriptions are made. Our principal aim is to uncover the socio-technical complexity of establishing an Information Infrastructure, a complexity which so far has been severely underestimated by those involved. By studying the process of aligning and linking one inscription to other inscriptions, we also hope to learn more about the strength of inscriptions, that is, the degree to which an inscription actually succeeds in enforcing a desired behaviour. The empirical basis of our analysis is a case-study of standardization processes of health Information Infrastructure from Norway.

developing Information Infrastructure the tension between standardization and flexibility
Science Technology & Human Values, 1996Co-Authors: Ole Hanseth, Eric Monteiro, Morten HatlingAbstract:This article explores the tension between standardization and flexibility in Information Infrastructure (II). Just like other large technical systems, the geographically dispersed yet highly interconnected II becomes increasingly resistant to change. Still, II design must anticipate and prepare for changes, even substantial ones, if Infrastructure is to survive. An II contains a huge number of components that alternate between standardization and change throughout their lifetimes. These components are interdependent: when one is changed, others have to remain stable, and vice versa. The article examines theoretical concepts for frammg these aspects of an II. The empirical underpinning of the article is a study of two existing embryonic manifestations of II.

social shaping of Information Infrastructure on being specific about the technology
arXiv: Computers and Society, 1996Co-Authors: Eric Monteiro, Ole HansethAbstract:In this paper, we discuss conceptualizations of the relationship between IT and organizational issues. To move beyond an “IT enables/constrains” position, we argue that it is necessary to take the specifics of an Information system (IS) more seriously. A theoretical framework called actor-network theory from social studies of science and technology is presented as promising in this regard. With respect to new organizational forms, the class of ISs which needs closer scrutiny is Information Infrastructures (INIs). They have characteristics which distinguish them from other ISs, namely the role and pattern of diffusion of standards. These standards are neither ready-made nor neutral: they inscribe organizational behavior deeply within their “technical” details. Diffusion and adoption of standards depart from other kinds of ISs by requiring the coordination of the surrounding actors, institutional arrangements and work practices.

integrating a perceptual Information Infrastructure with robotic avatars a framework for tele existence
Intelligent Robots and Systems, 1999Co-Authors: Hiroshi Ishiguro, Mohan M. TrivediAbstract:Describes an infrastructural framework to support interactivity among entities that are not residing in the same physical environment. In such an environment, mobile robots supported by a perceptual Information Infrastructure gather Information and communicate with people in a distant place instead of the users. This is one of the possible and promising applications of robots based on the current technologies of robotics, multimedia and computer networks. The paper describes the overall architecture and main system components. We discuss experimental studies where underlying concepts and algorithms are evaluated.

distributed vision system a perceptual Information Infrastructure for robot navigation
International Joint Conference on Artificial Intelligence, 1997Co-Authors: Hiroshi IshiguroAbstract:This paper proposes a Distributed Vision System as a Perceptual Information Infrastructure for robot navigation in a dynamically changing world. The distributed vision system, consisting of vision agents connected with a computer network, monitors the environment, maintains the environment models, and actively provides various Information for the robots by organizing communication between the vision agents. In addition to conceptual discussions and fundamental issues, this paper provides a prototype of the distributed vision system for navigating mobile robots.

A secure decentralized data-centric Information Infrastructure for smart grid
IEEE Communications Magazine, 2010Co-Authors: Young Jin Kim, Marina Thottan, Vladimir Kolesnikov, Wonsuck LeeAbstract:In recent years the power grid has been undergoing transformative changes due to the greater penetration of renewable energy sources and increased focus on power demand shaping. These innovative transformations on the grid require a flexible IP-based communication grid that is reliable and secure. In this article we describe an IPbased decentralized and data-centric Information Infrastructure that can reliably, securely, and cost-effectively support the operation and innovative applications of the next generation grid. The proposed Infrastructure differs from a typical distributed system since it addresses the specific requirements of power applications such as security, distributed data sources, latency sensitive data transactions and real time event updates. The work presented here paves the way for a future data-centric power network Infrastructure.
