Sharing and communicating health care information: summary and recommendations.
Sharing and communicating information is a fundamental task in modern medicine. The health care system of the western world is based on teamwork of professionals who participate in the care of patients. Exchange of information (not just data) requires the communicating parties to agree on a communication channel, an exchange protocol, and a common language. The language includes an alphabet, words, phrases, and symbols that express and assign meaning, understood by all. The most common forms of communication are the spoken word and the paper-based patient record. Computers and communication systems improve the sharing of health care information by overcoming the limitations imposed by the dimensions of time and location. However, natural language is still too complex and too ambiguous for current computing devices to handle the complex interactions between health care professional and patients. A simpler 'language' is needed that uses domain specific vocabularies (and/or codes), well-defined exchange protocols for data, information, knowledge, and, in the future, perhaps even wisdom. This simpler 'language' is expected to handle most of the routine information exchange but not eliminate natural language. It is essential that health care information systems preserve and incorporate natural language expressions and integrate them with structured vocabularies. Today, agreeing on standard data exchange protocols and domain specific vocabularies and codes is our greatest challenge. However, standards alone are not sufficient. Acceptance of the standards by the health care professionals, verifications in clinical environments, and implementation agreements by the medical informatics industry are essential. The group on 'Sharing and Communication of Health Care Information' addressed the issues raised above and unanimously recommends a number of steps that will improve the sharing of information. In addition, specific recommendations are offered to governments, health care institutions, and to developers of health care information systems.

Reorganization of the information technology program at a United States medical school: is there a lesson for academic medical informatics in Japan?
Reorganization of the information technology program at Baylor College of Medicine commenced with the goal of obtaining a client-focused organization instead of a classically departmental structure. Legacy organizations independently established by request or serendipity had gaps and overlaps in services and could no longer respond to new issues, such as integration of several hospitals, resource sharing of health care delivery, administration of a shared library, and an academic informatics program. The renewal of the information technology program has led to departments of Telecommunications, Enterprise Services, Client Services, and Medical Informatics, and has also allowed cross-departmental projects led by a technology architect. In contrast with that of Baylor, the approach of the Yamaguchi University School of Medicine in Japan may be construed as economic efficiency at the cost of client services. Effective client services by friendly and efficient staff groups is the most important factor for an academic information technology program, if the goal is to reorganize in anticipation of future challenges to the medical center.

Integrating non-proprietary workstations into proprietary systems.
'Clinical workstations', increasingly described as pivotal components of information systems for patient care, can be characterized as providing several major functions: access to data, presentation of data, computation (including medical decision logic), entry of data, and combinations of the above, integrated appropriately for various clinical situations. Because workstation technology is developing rapidly on many fronts and the demands on health-care organizations are growing, it is increasingly unlikely that any single total-system solution can effectively meet the needs. This paper discusses some of the issues pertinent to the integration of non-proprietary workstations with proprietary hospital systems. The approach of a particular vendor, the role of a meta-database, user interface design standards, and some problems consequent to the new technologies are discussed.

From multimodality digital imaging to multimedia patient record.
The constant improvement in computer power and performance nowadays offers convenient and efficient means of manipulating images, graphics, and movies on off-the-shelf workstations. With this improvement the trend toward integration of multimodality clinical documents from patient records comes naturally. Images and graphs are certainly the most important part of the complementary information that must accompany the text and numerical data. It is, however, possible to include sounds and voice messages together with all the other modalities. In medicine that could certainly help conveying hart murmur or sounds, but could also offer a convenient way of including vocal messages and comments. These new possibilities will certainly change the way physicians use workstations for direct communication. The computer industry will soon offer means of interactive communication between remote users through computer workstations. That alone will open a completely new era in cooperative computing and remote consultation scenarios in medicine. More than the technology itself, a complete change in behavior and work habits can be expected in the medical community.

Administrators' and health services researchers' requirements for workstations.
This paper offers a view of requirements for workstations, based on work currently going forward in the UK, some of which involves collaboration with partners in other European countries. In the UK, as elsewhere, interest in this subject has been lively for many years. The paper draws only on current and planned work, and does not attempt an historical resume. The status of the centrally-funded programme of work under the heading 'Integrated Clinical Workstation' (ICWS) is described. The project has put together a statement of user requirements. A Consensus Conference was held on 9 November 1992 at which an invited panel of clinicians, informaticians and suppliers met to discuss the way forward. A number of key areas and concerns were highlighted at this conference, of which the first was that the whole exercise needs to be clinically driven. The paper gives a brief account of projects in the UK and Europe which are beginning to address some of the requirements outlined above. The common thread through all these projects is a recognition that clinical workstation requirements have to be met by methods which cater to a wide variety of changing needs and approaches. No single static design will be sufficient.

Design of a clinical event monitor.
The issues and implementation of a clinical event monitor are described. An event monitor generates messages for providers, patients, and organizations based on clinical events and patient data. For example, an order for a medication might trigger the generation of a warning about a drug interaction. A model based on the active database literature has as its main components an event (which triggers a rule to fire), a condition (which tests whether an action ought to be performed), and an action (often the generation of a message). The details of implementing such a monitor are described, using as an example the Columbia-Presbyterian Medical Center clinical event monitor, which is based on the Arden Syntax for Medical Logic Modules.

An architecture for a health care provider's workstation.
This paper presents an architecture for a health care provider's workstation designed to assist health care providers in performing their daily activities. The design is based on the concept of a clinician's associate which acts as an intelligent intermediary between the provider and a diverse collection of clinical, administrative, and educational information sources. The architecture is designed to be hardware platform independent, to work across different I/O capabilities, and to be open, allowing specialized applications to be easily integrated with the system and their functionality delivered through a common user environment.

The role of the UMLS in 'storing' and 'sharing' across systems.
We will argue that 'sharing', 're-use', 're-purposing', and 'addition' of health care information is difficult, intrinsically; that the best way to overcome the difficulty is to start doing it, as soon as possible, and that the UMLS Knowledge Sources provide the best place to start. We recommend that the UMLS be used as a default source of biomedical concept names and relationships, as a comprehensive, data-based, 'reference model', and as an example of a large, ecumenical, evolving, continuously updated source of re-usable health care information.

Computers in the ICU: panacea or plague?
The introduction of the intensive care unit (ICU) in the 1960s with its demands for management of large volumes of patient data drove the initial introduction of computers into the ICU. Since the mid-1960s computer systems for the ICU have evolved into the highly sophisticated bedside workstations commercially available today. Despite all of the technologic advances in computers, their application in ICUs in the United States continues to spread very slowly. One of the largest problems is justifying the cost of systems primarily designed to automate data charting and generation of care plans. Although the existing commercial systems do an excellent job, few conclusive studies prove that these systems have a favorable cost-to-benefit ratio. Research systems have demonstrated that if one extends these systems to incorporate a fully integrated database, decision-support tools, automation of data acquisition, and more sophisticated display and user-interface technology, then these ICU computer systems can have a significant impact on improving the quality and reducing the costs of patient care. For computers to be embraced in the ICU environment, commercial systems of the future must move beyond merely gathering and displaying information. They must help the clinician at the bedside assimilate the vast array of ICU data and help him to make more effective decisions.

Health professional workstations and their integration in a hospital information system: the pragmatic approach MEDIAS.
Within the daily workload at a ward there is a considerable amount of information processing. It is the task of a systematic management of hospital information systems to provide health professionals with the right information in the right place at the right time. This paper deals with the consequences for the management of hospital information systems if health professional workstations are introduced as a means for this information logistic and with the experiences gained in the Heidelberg University Hospital. Health professional workstations are formally defined in the context of a three level graph-based model of hospital information systems. It is found that health professional workstations have communication needs not only on the physical level of computer systems in the hospital information system but also on the logical tool level, which is the level of application systems. On this level communication servers or brokers are of considerable importance. In Heidelberg there are about 200 health professional workstations (MEDIAS) in routine use.

Building a data foundation for tomorrow's healthcare information management systems.
Accurate, timely data are a necessary foundation for an effective healthcare information management system. Today's systems do not achieve their potential because they lack this essential ingredient. Technology can reduce the problem by making the data entry task easier, but a complete solution will require new strategies for system implementation and use. Functions must be implemented in a sequence that allows the initial functions to establish a data foundation for subsequent functions. Each atomic data item must be collected separately, with a consistent definition. Data capture strategies must permit data to be collected once, at the source. Finally, the data must be used, reused, and corrected by all members of the healthcare team.

IAIMS and sharing.
The Integrated Academic Information Management System (IAIMS) concept is about sharing resources and information, and about improving the decision-making ability of health care professionals by integrating information. At Columbia-Presbyterian Medical Center, the IAIMS project has established an information architecture based on common, shared computing and networking resources. The institutional computing culture has been changed with increased sharing of information and, consequently, improved quality of information. Several classes of information in the areas of clinical, scholarly, administrative, basic research, and core resources have been identified for better understanding of information responsibility. Technical problems such as heterogeneity on workstation platforms and lack of universal syntactic and semantic standards for health care information exchange still impede inter-institutional sharing of information.

BioSYNTHESIS: access to a knowledge network of health sciences databases.
Users of the IAIMS Knowledge Network at the Georgetown University Medical Center have access to multiple in-house and external databases from a single point of entry through BioSYNTHESIS. The IAIMS project has developed a rich environment of biomedical information resources that represent a medical decision support system for campus physicians and students. The BioSYNTHESIS system is an information navigator that provides transparent access to a Knowledge Network of over a dozen databases. These multiple health sciences databases consist of bibliographic, informational, diagnostic, and research systems which reside on diverse computers such as DEC VAXs, SUN 490, AT&T 3B2s, Macintoshes, IBM PC/PS2s and the AT&T ISN and SYTEK network systems. Ethernet and TCP/IP protocols are used in the network architecture. BioSYNTHESIS also provides network links to the other campus libraries and to external institutions. As additional knowledge resources and technological advances have become available. BioSYNTHESIS has evolved from a two phase to a three phase program. Major components of the system including recent achievements and future plans are described.

Global information infrastructure.
The High Performance Computing and Communications Program (HPCC) is a multiagency federal initiative under the leadership of the White House Office of Science and Technology Policy, established by the High Performance Computing Act of 1991. It has been assigned a critical role in supporting the international collaboration essential to science and to health care. Goals of the HPCC are to extend USA leadership in high performance computing and networking technologies; to improve technology transfer for economic competitiveness, education, and national security; and to provide a key part of the foundation for the National Information Infrastructure. The first component of the National Institutes of Health to participate in the HPCC, the National Library of Medicine (NLM), recently issued a solicitation for proposals to address a range of issues, from privacy to 'testbed' networks, 'virtual reality,' and more. These efforts will build upon the NLM's extensive outreach program and other initiatives, including the Unified Medical Language System (UMLS), MEDLARS, and Grateful Med. New Internet search tools are emerging, such as Gopher and 'Knowbots'. Medicine will succeed in developing future intelligent agents to assist in utilizing computer networks. Our ability to serve patients is so often restricted by lack of information and knowledge at the time and place of medical decision-making. The new technologies, properly employed, will also greatly enhance our ability to serve the patient.
