Improving access to knowledge-based health sciences information: early results from a statewide collaborative effort.

Access to biomedical literature has been shown to reduce the patient's length of stay and thus reduce the cost of the hospital visit. Unfortunately, access to the most current information, at the time and place of need, requires a substantial commitment of resources in the form of staff expertise, computer hardware and software, and user training. The cost of these resources may be prohibitively high for all but the largest institutions. The Arizona Health Information Network (AZHIN) brings together librarians, information systems specialists, and health care professionals from hospitals throughout the state in an effort to share resources and expertise. By reducing the cost of access, AZHIN has increased the availability of health-related information across the state. Progress in AZHIN's first two years is described.

Communicating science-based food and nutrition information.

Science evolves. Ongoing research, review and debate generate novel ideas and provide new insights to current scientific understanding. However, science is frequently reported to the public without context, which creates confusion. One study seemingly contradicts another, leaving consumers to doubt both scientific experts and science. This paper highlights quantitative and qualitative data to illustrate consumer confusion, frustration and apathy toward nutrition science and health information. Further, this paper shows how science communications and health advice can be tailored for specific audiences and, importantly, how scientists themselves can help the media understand and position research to minimize consumer confusion.

The scope and direction of health informatics.

Health Informatics (HI) is a dynamic discipline based on the medical sciences, information sciences, and cognitive sciences. Its domain can broadly be defined as medical information management. The purpose of this paper is to provide an overview of this domain, discuss the current "state of the art," and indicate the likely growth areas for health informatics. The sources of information used in this paper are selected publications from the literature of Health Informatics, HI 5300: Introduction to Health Informatics, which is a course from the Department of Health Informatics at the University of Texas Houston Health Sciences Center, and the author's personal experience in practicing telemedicine and implementing an electronic medical record at the NASA-Johnson Space Center. The conclusion is that the direction of Health Informatics is in the direction of data management, transfer, and representation via electronic medical records and the Internet.

A primer on aspects of cognition for medical informatics.

As a multidisciplinary field, medical informatics draws on a range of disciplines, such as computer science, information science, and the social and cognitive sciences. The cognitive sciences can provide important insights into the nature of the processes involved in human- computer interaction and help improve the design of medical information systems by providing insight into the roles that knowledge, memory, and strategies play in a variety of cognitive activities. In this paper, the authors survey literature on aspects of medical cognition and provide a set of claims that they consider to be important in medical informatics.

Medical informatics as a market for IS/IT.

Medical informatics is "the application of information science and information technology to the theoretical and practical problems of biomedical research, clinical practice, and medical education." A key difference between the two streams lies in their perspectives of "What Is Important in MI to Me?" MI may be seen as the marketplace where biomedicine consumes products and services provided by information science and information technology.

Humans, information and science.

The use of information forms the basis of nursing policies, standards and professional codes of conduct. Although used intuitively, nurses must now also grapple empirically with information needs often defined by others, and with the technology used to capture and process it. Even the briefest contemplation of 'information' reveals a truly pervasive concept. Information is ubiquitous. In order to care effectively in the so-called 'information age' health care professionals need to understand information. This paper is a small contribution to that effort, attempting to conjoin the disparate fields of health and the information sciences; and the basic sciences upon which they are based. This paper explores how definitions of information formulated in computing and communication theory relate to health and other aspects of human experience. The strategy adopted to achieve this is threefold. First, there is the vexed question of defining data, information and knowledge. Second, I consider how communication--that essential nursing activity--relates to information, meaning and the messages people seek to convey to each other. Thirdly, clinical situations are described in an information-oriented manner, using the concepts of 'redundancy' and 'entropy'. The conclusion provides an historical perspective.

The structure of medical informatics journal literature.

OBJECTIVE: Medical informatics is an emergent interdisciplinary field described as drawing upon and contributing to both the health sciences and information sciences. The authors elucidate the disciplinary nature and internal structure of the field. DESIGN: To better understand the field's disciplinary nature, the authors examine the intercitation relationships of its journal literature. To determine its internal structure, they examined its journal cocitation patterns. MEASUREMENTS: The authors used data from the Science Citation Index (SCI) and Social Science Citation Index (SSCI) to perform intercitation studies among productive journal titles, and software routines from SPSS to perform multivariate data analyses on cocitation data for proposed core journals. RESULTS: Intercitation network analysis suggests that a core literature exists, one mark of a separate discipline. Multivariate analyses of cocitation data suggest that major focus areas within the field include biomedical engineering, biomedical computing, decision support, and education. The interpretable dimensions of multidimensional scaling maps differed for the SCI and SSCI data sets. Strong links to information science literature were not found. CONCLUSION: The authors saw indications of a core literature and of several major research fronts. The field appears to be viewed differently by authors writing in journals indexed by SCI from those writing in journals indexed by SSCI, with more emphasis placed on computers and engineering versus decision making by the former and more emphasis on theory versus application (clinical practice) by the latter.
