The health sciences librarian as Internet navigator and interpreter.

Over the past several years, thousands of networked information resources have become available to individuals and institutions with access to the Internet. Unfortunately, the dizzying array of computing and networking environments often frustrates end users' attempts to navigate the Internet. Librarians have begun to take responsibility not only for instructing users in the use of basic network tools such as file transfer, remote log-in, and electronic mail, but also for answering questions concerning network access and even information system design. The authors show how, by continuing to adapt to this new and volatile environment, health sciences librarians find themselves playing increasingly important roles in shaping the information policies and practices of their institutions. To illustrate these new roles, the authors review the experiences of health sciences librarians at the University of California, Los Angeles, and the University of California, San Diego. These institutions have varying and complex networking environments, and their biomedical libraries have taken lead roles in clarifying and interpreting their particular Internet features.

Managing secure computer systems and networks.

No computer system or computer network can today be operated without the necessary security measures to secure and protect the electronic assets stored, processed and transmitted using such systems and networks. Very often the effort in managing such security and protection measures are totally underestimated. This paper provides an overview of the security management needed to secure and protect a typical IT system and network. Special reference is made to this management effort in healthcare systems, and the role of the information security officer is also highlighted.

Evolving community health information networks.

A community health information network (CHIN) provides technology-based information services to help maintain optimal health for all the residents of a community. Defining features of a CHIN are that its services are available to all stakeholders and that competitors collaborate to share information. The initial impetus for a CHIN is usually to facilitate paying for health care or to share clinical records. Complex legal, organizational, funding, and control issues confront CHIN initiators, and reliable models do not exist today. During development, issues of program focus and technology selection arise, followed by concerns about information privacy and the CHIN's role in quality of care. Once basic capabilities are implemented, a mature CHIN can offer extensive cost-recovering health-related services to providers, related agencies, and consumers. Developments are underway that eventually will allow a CHIN to support a fully integrated longitudinal health record. A national network of mature CHINs would offer health care professionals further collaborative possibilities that could change the shape of future health care.

Information technology, Part 3. The technology hierarchy.

The era of the networked society--and medical care depending on networked intelligence--is dawning. Physicians need to plan for office practice information systems in common, with an eye to conveying data electronically between all the locations of care and all the providers involved in caring for defined populations of people. The shared database will become the most important asset of the collection of providers who make up the delivery system that creates it. This will be accomplished by layering technology on local and wide-area networks of group practices, hospitals, health plans, and payers and developing standards that make data accessible in the same format to all users, no matter where they are.

[Cost effectiveness and patient benefit of digital image management systems for radiology].

In many countries today, politicians are faced with the difficulty of having to reduce the overproportional increase in the cost of healthcare. In this context the contribution of medical technology to costs in the total spent are nearly always overestimated and its potential for savings underestimated. Based on international studies, investment and subsequent running costs for large, high-tech systems for diagnosis and therapy will be shown to account for only about 1% of the total cost of healthcare. Impressive examples of the application of computed tomography, magnetic resonance tomography and digital angiography deliver statistics regarding valid patient benefits and efficiency of modern diagnostic imaging systems. Studies about related therapeutic possibilities of angioplasty and extra-corporal lithotripsy demonstrate the overall economic advantages of modern medical technology. Arising from the positive results due to the use of such equipment, the additional cost savings potential to be expected by networking these digital modalities with one another, as well as with other information and communications technology systems, will be analysed. The results will be assessed and compared to experience gained from routine clinical operation of such integrated systems. 72% of the total turnover of the Medical Engineering Group of Siemens AG for diagnostic imaging modalities in 1991/1992 arose from digital imaging modalities, and this percentage is expected to continue to increase. This paper will concentrate on these modern digital methods.

Molecular dynamics simulation on a network of workstations using a machine-independent parallel programming language.

Molecular dynamics simulations investigate local and global motion in molecules. Several parallel computing approaches have been taken to attack the most computationally expensive phase of molecular simulations, the evaluation of long range interactions. This paper develops a straightforward but effective algorithm for molecular dynamics simulations using the machine-independent parallel programming language, Linda. The algorithm was run both on a shared memory parallel computer and on a network of high performance Unix workstations. Performance benchmarks were performed on both systems using two proteins. This algorithm offers a portable cost-effective alternative for molecular dynamics simulations. In view of the increasing numbers of networked workstations, this approach could help make molecular dynamics simulations more easily accessible to the research community.

A high-speed network for cardiac image review.

A high-speed fiber-based network for the transmission and display of digitized full-motion cardiac images has been developed. Based on Asynchronous Transfer Mode (ATM), the network is scaleable, meaning that the same software and hardware is used for a small local area network or for a large multi-institutional network. The system can handle uncompressed digital angiographic images, considered to be at the "high-end" of the bandwidth requirements. Along with the networking, a general-purpose multi-modality review station has been implemented without specialized hardware. This station can store a full injection sequence in "loop RAM" in a 512 x 512 format, then interpolate to 1024 x 1024 while displaying at 30 frames per second. The network and review stations connect to a central file server that uses a virtual file system to make a large high-speed RAID storage disk and associated off-line storage tapes and cartridges all appear as a single large file system to the software. In addition to supporting archival storage and review, the system can also digitize live video using high-speed Direct Memory Access (DMA) from the frame grabber to present uncompressed data to the network. Fully functional prototypes have provided the proof of concept, with full deployment in the institution planned as the next stage.

The CD-ROM experience at Loma Linda: the issues of training, logistics, and creative financing.

Since the end of 1987, the Medical Center and University libraries at Loma Linda have progressed from stand-alone CD-ROM-based workstations for access to MEDLINE to networked CD-ROM access to a variety of databases. T.O.M.M.I. (Total Online Medical Material Integration) is a CD-ROM-based wide area network linking the Loma Linda University Medical Center, Loma Linda University, and other entities in Loma Linda, California. T.O.M.M.I., a microcomputer-based system, represents the implementation of IAIMS at Loma Linda. In addition to discussing the issue of "downsizing" campus-wide information networks, this article focuses on the issues of training, handling of logistical problems, and the use of creative financing.

[Long-term experience with a PACS subsystem].

Our experiences with a PACS-Subsystem have shown, that it would be more usefull and less expensive, first to install digital archiving systems in single areas. After a certain time of errorfree working the subsstems should be integrated into a superior information system. Fast data networks and userfriendly viewing stations are a basic requirement. Common standards of archiving, independent of the manufacturer, should be considered.

Overview of an architectural approach to the development of the Johns Hopkins Hospital distributed clinical information system.

The Johns Hopkins Hospital has initiated an ambitious program to apply modern technologies to the development of a new, comprehensive clinical information system. Since many components of a system exist and since the JHH management is decentralized, a distributed, networked system is being built. To properly accomplish this task an architectural basis for strategic systems planning was developed. This paper reviews briefly the layered architectural approach.

Implementing network security guidelines in health care information systems.

A Health Care Establishment (HCE) is an establishment where medical services are rendered. These services are provided by the health care personnel. The infrastructure of a HCE may include Information Technology (IT) equipment that stores and processes HC information. The spread of distributed information technology in HCEs have necessitated the implementation of Network Security in Health Care Information System (HCISs), to assure confidentiality, integrity and availability of HC information being transmitted across HC networks. This paper presents a road map in implementing Network Security guidelines for the provision of Network Security in HCEs, work carried out within the Secure Environment for Information Systems in Medicine (SEISMED) project under the Advanced Informatics in Medicine (AIM) programme.

Information technology and the clinical curriculum: some predictions and their implications for the class of 2003.

Information technology, medical knowledge, and medical practice are on a collision course. The consequences of the impact will change the way physicians work, the way medical knowledge is processed, packaged, and distributed, and the way patients obtain medical care and information. Today's educators need to design an information technology curriculum to prepare students for this emerging world of practice. Computer labs, based on today's complex and unreliable desktop systems, are not the answer. What is needed by students who entered medical school in 1997-98 is an informatics curriculum that is based on the real-world requirements of 2003 and beyond. The authors draw upon academic studies and their own clinical and industry experiences to outline some predictable elements of what lies ahead. Their predictions--ubiquitous, simple network computing and "power tools" for managing medical knowledge--have implications for how schools cover such educational topics as patient confidentiality, systems thinking and error management, and knowledge resource evaluation.
