The evolution of the IAIMS: lessons for the next decade.

The Integrated Academic (Advanced) Information Management System (IAIMS) initiative emerged in the early 1980s to respond to trends in biomedical information, transfer and access, and to identify the implications for health sciences libraries. Three recurrent themes have emerged as being essential to the creation of IAIMs: changing the paradigm; redirecting expenditures to build reuseable infrastructure; and working across cultural boundaries. An IAIMS penetrates an organization in four stages: from creating awareness; through development of foundation infrastructure; through integration as an extra effort; to integration as a byproduct of organizational structure and information architecture. Extension of the IAIMS to support a regional area is a natural fifth stage that reapplies the processes of the first four stages and re-uses the infrastructure that has been built within the cooperating organizations. Area IAIMSs have the potential to transform biomedicine by enabling new paradigms for manpower development and publication of information.

Major issues in user interface design for health professional workstations: summary and recommendations.

Lack of good user interfaces has been a major impediment to the acceptance and routine use of health-care professional workstations. Health-care providers, and the environment in which they practice, place strenuous demands on the interface. User interfaces must be designed with greater consideration of the requirements, cognitive capabilities, and limitations of the end-user. The challenge of gaining better acceptance and achieving widespread use of clinical information systems will be accentuated as the variety and complexity of multi-media presentation increases. Better understanding of issues related to cognitive processes involved in human-computer interactions is needed in order to design interfaces that are more intuitive and more acceptable to health-care professionals. Critical areas which deserve immediate attention include: improvement of pen-based technology, development of knowledge-based techniques that support contextual presentation, and development of new strategies and metrics to evaluate user interfaces. Only with deliberate attention to the user interface, can we improve the ways in which information technology contributes to the efficiency and effectiveness of health-care providers.

Active X based standards for healthcare integration.

With cost pressures brought to the forefront by the growth of managed care, the integration of healthcare information systems is more important than ever. Providers of healthcare information are under increasing pressure to provide timely information to end users in a cost effective manner. Organizations have had to decide between the strong functionality that a multi-vendor 'best of breed' architecture provides and the strong integration provided by a single-vendor solution. As connectivity between systems increased, these interfaces were migrated to work across serial and eventually, network, connections. In addition, the content of the information became standardized through efforts like HL7 and ANSI X12 and Edifact. Although content-based standards go a long way towards facilitating interoperability, there is also quite a bit of work required to connect two systems even when they both adhere to the standard. A key to accomplishing this goal is increasing the connectivity between disparate systems in the healthcare environment. Microsoft is working with healthcare organizations and independent software vendors to bring Microsoft's powerful enterprise object technology, ActiveX, to the healthcare industry. Whilst object orientation has been heralded as the 'next big thing' in computer applications development, Microsoft believe that, in fact, component software is the technology which will provide the greatest benefit to end users.

[RIS modality interfaces. From proprietary solutions to DICOM worklist management].

Radiologic information systems (RIS) and picture archiving and communication systems (PACS) are becoming increasingly widespread. This leads to new demands on the integration of the individual, formerly independent information systems (RIS, modalities, PACS). Possible ways of integrating individual systems are introduced. Besides the detailed description of different realizations of system communication, its role in the PACS at the university hospital in Freiburg is explained. The integration of different information systems still requires the use of proprietary interfaces. An appropriate integration generally has been realized in Freiburg. In the near future DICOM basic worklist management will standardize system integration and render an interdepartmental workflow concept possible. Even though an available communication standard exists, not all problems in the RIS-modality interface are solved. Different data models in the various RI systems and modalities demand certain degrees of freedom in the standard. Thus a satisfactory workflow cannot be guaranteed even when all involved systems conform with the standard.

Medical data and knowledge management by integrated medical workstations: summary and recommendations.

The health care professional workstation will function as an interface between the user and the patient data as well as an interface pertinent medical knowledge. Appropriate knowledge focus will require the workstation to recognize the concepts and structure of patient data, and understand the scope and access methods of knowledge sources. Issues are organized around five major themes: (i) structure, (ii) reliability and validation, (iii) views, (iv) location, and (v) ethical and legal. Conventional database representations can effectively address data structure and format variations that will inevitably persist in local data stores. The reliability of data and the validation of knowledge are critical issues that may determine the ultimate utility of clinical workstations. Alternative views of patient information and knowledge sources represent the true power of an intelligent data portal, represented by a well-designed clinical workstation. Both data and knowledge are optimally represented in decentralized information networks, although the confidentiality and ownership of this information must be respected. Evolutionary progress toward consistent representations of knowledge and patient data will be facilitated by the establishment of self-documentation standards for the developers of data encoding systems and knowledge sources, perhaps extended from the preliminary model afforded by the Unified Medical Language System (UMLS).

[Telemedicine stroke department network. Introduction of a telemedicine pilot project for integrated stroke management in South Bavaria and analysis of its efficiency].

More than 100 stroke units have been established in Germany. In rural areas, however, acute stroke care needs to be improved. In order to advance clinical stroke therapy, two specialized stroke centers founded a telemedicine network (TEMPiS) among 12 community hospitals in eastern Bavaria. Each network hospital established specialized stroke wards where qualified teams manage acute stroke patients. Twenty-four hours daily, physicians in local hospitals are able to contact the stroke centers via videoconferencing including transmission of digital DICOM data. To study the efficacy of this network, a controlled trial will be performed. Five TEMPiS-network hospitals will be matched with five other hospitals equal in size, catchment area, and diagnostic techniques. For about 1 year, all consecutive stroke cases in the matched study hospitals will be prospectively recorded in a database. Neurological deficits will be quantified on the National Institute of Health Stroke Scale within 24 h after stroke onset. Mortality and institutional care as a combined primary endpoint will be assessed after 3 and 12 months. Furthermore, functional outcome according to the modified Rankin scale, Barthel score, and quality of life will be assessed using a standard telephone interview. Data acquisition started in July 2003, and final results are expected in 2005.

Knowledge integration: insight through the E-portal.

Data become information when they can be summarized and organized into logical patterns; information becomes knowledge when it can be manipulated for actionable decision making; knowledge becomes insight when contextually relevant and temporarily appropriate. This article describes how information technology can now be used to provide clinicians with access to both insight and information that is context- and event-sensitive. Collaboration between the American College of Physicians, medical knowledge experts, Oregon Health Sciences University (OHSU), and shared medical systems for framework and infrastructure combine to create the ideal environment of complementary and synergistic competencies. This article describes the research that is under way at OHSU to determine how to deploy medical knowledge derived from these sources and integrate it into the clinical workflow; it also examines a vision of how medical knowledge can be integrated in the future.

Digital image management and communication in medicine.

With the rapid development of digital imaging modalities in medicine, there is an increasing need for an efficient management and archival of medical images in digital form. Picture Archiving and Communication Systems (PACS) are becoming an essential component of medical imaging equipment, allowing for medical images to be accessed and stored directly in digital form. This paper describes a hospital-wide PACS currently under development at the University Hospital of Geneva, based on an open architecture, regrouping equipment from different vendors in a distributed topology. The image archival is organized in multiple locations geographically distributed in the hospital. The PACS database is fully integrated with the concurrent Radiology Information System (RIS) and Hospital Information System (HIS). A standard image storage format called the PAPYRUS format was developed for the storage of medical images from a variety of imaging modalities. To provide a more uniform user interface on a variety of different workstations, a common platform for image display and manipulation called OSIRIS was developed.

Clinical workstations: identifying clinical requirements and understanding clinical information.

A preliminary exploration of the problem of defining and meeting users' needs, this paper draws the bulk of its content from experiences in the PEN&PAD project in the UK. This program has been researching and developing prototype clinical workstations for direct use in patient care by health care professionals, chiefly doctors. Focusing more on general issues rather than the specific functional requirements embodied in the PEN&PAD prototypes, the paper begins with a brief summary of the goals of PEN&PAD and then outlines the three main axes of the work: user-centred design, medical concept and medical record models, and user interfaces and architectures. The remainder of the paper then concentrates on the first of these topics--working with users to define functional requirements.

Integration of a handheld based anaesthesia rounding system into an anaesthesia information management system.

BACKGROUND: At the University Hospital Giessen, an anesthesia information management system (AIMS) is used for online record keeping of perioperative patient care, but preoperative anaesthesia assessments were still being recorded on paper and subsequently entered into the AIMS. Personal digital assistants (PDAs) seem to be useful instruments to establish a seamless digital anesthesiological documentation. OBJECTIVES: We decided to implement a solution for direct integration of data gathered during the preoperative assessment into the existing data management infrastructure. Parallel to the development of the system, we surveyed the future users to match their wishes and needs as far as possible. SYSTEM DESCRIPTION: A C program embedding the preoperative AIMS' data fields was developed. Data alignment with the Hospital information system (HIS) is controlled by a Java desktop software. The anaesthesiologist completes the available fields at the patient's bedside following the same algorithm and integrity check as the PC version. STATUS REPORT: Overall, 68% of the surveyed physicians supported the implementation of the system. The PDA solution has been available since May 2002. Data replication into the handheld and integration of mobile collected data into the AIMS generally work without problems. The HIS interconnection software converts the PDA file into the AIMS format for further processing. DISCUSSION: The preoperative anaesthetic assessment is a standardised task well suitable for conversion to an electronic data storage medium. Changing from redundant data entry in the OR to direct electronic recording at the patient's bedside seems simply logical. Handheld computers are inexpensive, flexible gadgets to realize this.

[Modern network technologies for data communication in the hospital].

Modern network technologies provide the basic infrastructure for information and communication systems in the hospital today. The goal to build up a universal network infrastructure which meets the broadly varied requirements. Analysis of data communication in the hospital and the evaluation of established network technologies, as well as new developments, leads to the switching concept as the suitable solution. Two technologies play the major role in building enterprise networks: the Ethernet family, based on frame switching, and ATM, based on cell switching. Orientation on established standards is the key to free system choice and grants interoperability between systems from different manufacturers. However, the network design must meet the application and system architecture of the information technology in order to achieve successful mapping of the involved communication profiles. This means scaling of the bandwidth as needed, suitable segmenting of the network and resilient links. In a further step, policy-based networking takes advantages of prioritizing critical applications and therefore reduces interdependencies across the network.

Workstation network system which enables international exchange of characters and images at the University of Tokyo Hospital.

The circumstances when physicians want to exchange information are analyzed and the necessary requirements for workstations are discussed. Although there are many requirements, it will not be necessary to incorporate every requirement onto a single workstation. In the international setting, the capability of handling non-alphabetic characters is also important. The requirements for image display should be classified for those physicians who make their diagnosis primarily on the basis of images and those who use images as additional diagnostic information. On the basis of these discussions, the system of the University of Tokyo Hospital, which is now being implemented, is described. The system will be a network of approximately 300 workstations with one mainframe computer.

Remote connection to the Kyushu University Medical Center LAN using digital and analog telephone lines.

SOHO (Small Office/Home Office) has recently become popular, as it makes working at home possible. Computers or Local Area Networks(LAN) connected to the office network from home are necessary for the implementation of this concept. Kyushu University has begun a service connecting home computers to the campus LAN for researchers, staff and students of the Faculty of Medicine. We have two different telephone connection methods. One connects the campus LAN and the home computer LAN using routers through the Integrated Services Digital Network (ISDN). The other connects computers at home to the workstation in the university, using modems and the PPP (Point to Point Protocol) through a public telephone analog line. This paper outlines our university SOHO connection system and discusses the merits and demerits of using telephone line connections.

Information technology for detecting medication errors and adverse drug events.

It is estimated that over three-quarters of a million people are injured or die in hospitals each year from adverse drug events (ADEs). The majority of medical errors result from poorly designed healthcare systems rather than from negligence on the part of healthcare providers. In general, healthcare systems rely on voluntary reporting, which seriously underestimates the number of medication errors and ADEs by as much as 90%. This paper reviews the causes and impact of medication errors and ADEs. It also reports studies that have used information technology (IT) to detect and prevent medication errors and ADEs. Significant reduction of medication errors and ADEs requires systemic implementation of IT, improvements in the reporting of errors, and integration of the components of the healthcare systems' information systems. At the present time, most healthcare systems should be able to use IT to detect and prevent ADEs.

Full-text document storage and retrieval in a clinical information system.

The overall design of the CIS at CPMC is heavily influenced by the decision support component. The type of automated decision support being implemented dictates the need for highly structured or coded data. The value of decision support systems has been well documented. The current reliance on free-text documents is natural and a rewarding first step to a more valuable mix of coded and free text. While the health care provider might find the textual comments of the various reports extremely useful, the capability of an automated system to vigilantly review every data element for trends and anomalies is becoming invaluable in today's ever more complex health care delivery environment. Other approaches such as optical imaging systems would facilitate human decision support, but do not supply data in a format that can be processed by automated decision support systems. The developers of the CIS at CPMC believe that data are most valuable when available for both human and automated decision support.
