Beyond the superhighway: exploiting the Internet with medical informatics.

As in other areas of society, the Internet and the World Wide Web are becoming important topics in medical informatics. This is evident from the recent American Medical Informatics Association's 1996 Annual Fall Symposium, where the theme was "Beyond the Superhighway: Exploiting the Internet with Medical Informatics." Of the over 330 papers and abstracts published in the Proceedings, one third dealt with the Internet and/or the Web. In some cases, system developers demonstrated how this technology can do old tasks in new ways. In other cases, researchers described new tasks that are now possible with this technology. Still others examined this technology to show how it can be evaluated and improved. This paper summarizes their accomplishments.

[Informatics support to medical diagnosis. General information obtained from a first structured contact with the patient].

BACKGROUND: The methods and characteristics of clinical data gathered at the initial steps of development of a computerized system to aid medical diagnosis are reported. The objectives of the study were as follows: to describe the overall method and to set a framework for developing an intellectual model of the medical diagnosis procedure. MATERIAL AND METHODS: A structured medical interview and physical examination using an informatic program on PC compatible portable computers were completed in a sample 1,238 patients attending the outpatient clinics of our institution. Data obtained were compared with information in the patient's medical record taking as reference pattern the record of physicians in charge of the patients. Diagnosis were codified according to WHO International Classification of Diseases (ICD-9-CM). RESULTS: The distribution of symptoms and signs corresponding to the different organs and systems was analyzed. Each subdivision afforded a range of 1.3 to 3.9 abnormal findings per patient. A total of 3,571 diagnoses were codified for the whole group 1,238 patients with a mean (standard deviation) of 3 (2) diagnoses per patient (range 0-12). The distribution of diagnostic groups varied depending on the consideration of the main diagnosis or the concomitant diagnoses that defined the patient's clinical context. The most frequent main diagnoses included tumors, cardiovascular diseases, gastrointestinal disorders, and genitourinary tract diseases. CONCLUSIONS: As shown by results obtained in a sample of 1,238 patients, there is a very complex situation in clinical practice due to the simultaneous occurrence of several clinical patterns. This finding should be taken into account when developing clinical decision making support systems. The use of a structured medical interview or a structured and standard medical visit may be an adequate tool to clarify this matter and to contribute to standardization of clinical concepts and situations.

Where does informatics fit in health care organizations?

Why is medical informatics important to health care leaders? As an emerging science, informatics focuses on applying computing and communication technology to decision making for clinicians and managers. It enhances the understanding of how information and communication systems can impact the work health care managers must accomplish. As the cost of technology for digital information management continues to decline, organizations and individuals will look for ways to offset the human costs of managing and conveying information. The way of the paper medical record is being replaced by the less expensive and more efficient digital information systems. Leaders of health care organizations need to look for every opportunity to deploy networks and computers to reduce the labor costs of data collection, storage, retrieval, and analysis.

Medical informatics: an emerging medical discipline. Council on Scientific Affairs and Council on Long Range Planning and Development of the American Medical Association.

The use of computer technology in medicine is no longer the domain of only a few "gadget" happy high-tech aficionados. The rapid pace of medical progress and the increasing demands on physicians' time mandate that mechanisms be developed to deliver the tools of contemporary information management directly into the hands of all practicing physicians. It is with this intent that the Council on Long-range Planning and Development and the Council on Scientific Affairs of the American Medical Association have developed an informational report on Medical Informatics. The technology for producing information about medicine and patients is well into the information age. However, the technology for managing this information has not kept up, at least to the extent of being available in medical facilities where it is needed. Most users of medical information, physicians included, have not crossed the threshold into the electronic/computer era of information acquisition, distribution, and assimilation. The continuing development of the physician as computer user will create a more efficient work environment for the physician while at the same time improving patient care.

Informatics in radiology (infoRAD): A complete continuous-availability PACS archive server.

The operational reliability of the picture archiving and communication system (PACS) server in a filmless hospital environment is always a major concern because server failure could cripple the entire PACS operation. A simple, low-cost, continuous-availability (CA) PACS archive server was designed and developed. The server makes use of a triple modular redundancy (TMR) system with a simple majority voting logic that automatically identifies a faulty module and removes it from service. The remaining two modules continue normal operation with no adverse effects on data flow or system performance. In addition, the server is integrated with two external mass storage devices for short- and long-term storage. Evaluation and testing of the server were conducted with laboratory experiments in which hardware failures were simulated to observe recovery time and the resumption of normal data flow. The server provides maximum uptime (99.999%) for end users while ensuring the transactional integrity of all clinical PACS data. Hardware failure has only minimal impact on performance, with no interruption of clinical data flow or loss of data. As hospital PACS become more widespread, the need for CA PACS solutions will increase. A TMR CA PACS archive server can reliably help achieve CA in this setting.

Participatory design of a text message scheduling system to support young people with diabetes.

Effective self-management of diabetes requires considerable behavioural change and continuous support from health professionals, which can be expensive. Information technology has the potential to offer cost-effective patient support, but internet use mostly relies on the active seeking of information. Text messaging offers an ideal channel for delivering 'push' support and facilitating reciprocal communication between patient and health professional. This paper describes a participatory design methodology to develop a text message scheduling system for supporting young people with diabetes. The project illustrates how this familiar design approach can be used in a short-term project to deliver a successful medical application. Close working between clinician and software developer led to successive user-informed iterations as the clinician became more aware of the system's potential and identified barriers. The result was a reliable, functional, acceptable and usable system that was effectively implemented in its intended setting.

Navigation in medical Internet image databases.

The world wide web (WWW) changes common ideas of database access. Hypertext Markup Language allows the simultaneous presentation of information from different sources such as static pages, results of queries from) databases or dynamically generated pages. 'Therefore, the metaphor of the WWW itself as a database was proposed by Mendelzon and Nlilo in 1998. Against this background the techniques of navigation within WWW-databases and the semantic types of their queries has e been analysed. Forty eight image repositories of different types and content, but all concerning medical essence, have been found by search-engines. Many different techniques are offered to enable navigation ranging from simple HTML-link-lists to complex applets. The applets in particular promise an improvement for navigation. Within the meta-information for querying, only ACR- and UMLS-encoding were found, but not standardized vocabularies like ICD10 or Terminologia Anatomica. UMLS especially shows that a well defined thesaurus can improve navigation. However, of the analysed databases only the UMLS 'metathesaurus' is currently implemented without providing additional navigation support based on the UMLS 'semantic network'. Including the information about relationships between the concepts of the metathesaurus or using the UMLS semantic network could provide a much easier navigation within a network of concepts pointing to multimedia files stored somewhere in the WWW.

Collaboration between unlikely disciplines in the creation of a conceptual framework for nurse-computer interactions.

A unique conceptual framework for the study of nurse-computer interaction was created through the collaboration of two researchers in seemingly diverse fields: nursing informatics and developmental psychology. The framework depicts nurses and computers interacting in a system of mutual influences, exchanging information during a particular task, and proceeding on a developmental trajectory. The conceptual framework can help guide research within nursing informatics and help build a cohesive body of knowledge for the future.

Information management & decision support systems in the intensive care unit.

Management of the vast array and sheer volume of clinical data generated during the care of the critically ill patient is a formidable task. Not only must the data be acquired accurately, but it must be retrievable readily and in an interpretable form. Such characteristics are essential features, but the mere uncritical compilation of biomedical data barely takes advantage of the enormous computing power that is available at the bedside. A complete medical informatics package can assist the caregiver with clinical decision making, suggest or even carry out changes in management, and provide continuous, always vigilant surveillance for both dangerous alterations in physiology or ill-advised orders. For optimal implementation, knowledge of the origin, synthesis, and utility of clinical information is essential. A successful implementation using the skills of physicians, nurses, biomedical engineers, computer scientists, and hospital administrators must be collaborative. The characteristics of a clinical information system were defined recently by the Institute of Medicine of the National Academy of Sciences (Table 1). However, even the ideal system, implemented and administered by a harmonious and committed team, will not ensure clinical acceptance. The issue of accessibility can become paramount. If the system is not responsive to the needs of the occasional user, a great deal of expensive hardware will not be used to its full capability.

Assessment of the level of the actual and desirable levels of computer literacy, usage and expected knowledge of undergraduate students of nursing.

The aim of the study was to determine the perceptions of students entering nursing at the bachelors level, of their actual and desirable knowledge about computers and their applications relevant to nursing and health care. Within the health care system the use of computerized systems is increasing rapidly. In Australia, the NSW Health Department's Information Management Resource Consortium pilot project--to introduce the First Data Hospital Information System into NSW public hospitals--is a significant example of this trend. While the importance of computerized systems is fairly well recognized for the areas of management and research, they are becoming increasingly significant in the delivery of clinical care and quality assurance. It is important that nurses during their undergraduate education develop the computer literacy and awareness that will allow them access to the both the information and its management. To achieve this effectively it is essential to determine both the entry knowledge of students and what skills and knowledge are essential and desirable for their future roles as nurses. The research undertaken replicated an American study [2] and used their validated questionnaire. Both pre-registration(n=20) and post-registration (n=24) undergraduate students responded to a 21 item questionnaire. The issues addressed related to computer literacy, usage, and knowledge of clinical applications. Both groups desired more "hands on" experience and knowledge in the nurse's role in developing applications and using computers to help care for patients. These results were consistent with the Parks et. al. study. The significance of comparing actual and desirable levels of computer knowledge and awareness is in assisting educators to shape curriculum and course content to more effectively meet the educational needs of these groups in terms of Health Informatics.
