Medical affective computing: medical informatics meets affective computing.

"The need to cope with a changing and partly unpredictable world makes it very likely that any intelligent system with multiple motives and limited powers will have emotions." [1] From advisory systems that understand emotional attitudes toward medical outcomes, to wearable computers that compensate for communication disability, to computer simulations of emotions and their disorders, the research agendas of medical informatics and affective computing--how and why to create computers that detect, convey, and even have emotions--increasingly overlap. Some psychiatric and neurological researchers state their theories in terms of actual or hypothetical computer programs. Adaptive intelligent systems will increasingly rely on emotions to compensate for their own conflicting goals and limited resources--emotional reactions about which psychiatrists and neurologists have special insights. DEP2 (Depression Emulation Program 2) is a computer simulation of adaptive depression--learning from explainable patterns of failure in autobiographical memory--that simulates many depressive behaviors. In the terminology of fault-tolerant computing, adaptive depression involves fault detection (triggered by failure), fault location (strategic retreat and failure diagnosis), and fault recovery (return to on-line operation). DEP2 relies on subsystems whose structures and behaviors are based on popular hypotheses about left and right brain hemispheric function during depression and emotion. DEP2 and its predecessors, DEP and DEPlanner, are relevant to psychiatric and neurological informatics, and to the design of adaptive autonomous robots and software agents.

Applied medical informatics and computing skills of students, residents, and faculty.

BACKGROUND AND OBJECTIVES: Little is known regarding the applied medical informatics and computing skills of family practice residents and faculty, yet such information is critical when planning a medical informatics curriculum. We conducted a survey at our institution to collect this information. METHODS: An applied medical informatics and computing skills survey was administered to 93 first-year medical students, 42 family practice residents, and 14 family medicine faculty. Responses were compared between groups before and after stratification by age and gender. RESULTS: A total of 92% of students, 100% of residents, and 79% of faculty responded. Faculty had the highest rate of computer ownership (91%), followed by students (86%) and family practice residents (79%). Students and interns had the highest overall confidence using computers, followed by faculty and then senior residents. Faculty, students, and junior residents were significantly more confident than senior residents in their ability to perform several specific tasks, such as conducting a MEDLINE search. Residents perceived lack of money and time as barriers to improving their skills. CONCLUSIONS: Current senior residents may require remedial training to graduate with the computer skills specified in curricular guidelines. While upcoming medical students and interns will demand more advanced training, faculty may not have the skills to provide it.

Recommendations for responsible monitoring and regulation of clinical software systems. American Medical Informatics Association, Computer-based Patient Record Institute, Medical Library Association, Association of Academic Health Science Libraries, American Health Information Management Association, American Nurses Association.

In mid-1996, the FDA called for discussions on regulation of clinical software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology has developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. Organizations assisting in development of recommendations, or endorsing the consortium position include the American Medical Informatics Association, the Computer-based Patient Record Institute, the Medical Library Association, the Association of Academic Health Sciences Libraries, the American Health Information Management Association, the American Nurses Association, the Center for Healthcare Information Management, and the American College of Physicians. The consortium proposes four categories of clinical system risks and four classes of measured monitoring and regulatory actions that can be applied strategically based on the level of risk in a given setting. The consortium recommends local oversight of clinical software systems, and adoption by healthcare information system developers of a code of good business practices. Budgetary and other constraints limit the type and number of systems that the FDA can regulate effectively. FDA regulation should exempt most clinical software systems and focus on those systems posing highest clinical risk, with limited opportunities for competent human intervention.

Multimedia in the radiology environment: current concept.

Multimedia has different meanings according to its context. Here, multimedia in the radiology environment is defined as the integration of multiple radiology and medical information systems to facilitate the practice of radiology. These information systems include the hospital information system, radiology information system, picture archiving and communication systems, voice reporting, library information systems, and electronic mail and file systems. The concept of multimedia within the context of integration of these database systems will be presented. An example is given on how to access these information systems by a radiologist's desktop personal computer.

The questions of medical informatics.

Each science is identified with the questions it raises with respect to its object of study. This paper discussed the formulation of the basic questions of medical informatics. From a historical point of view, it first dealt with the problems of medical computing. Thereby, three classical questions arose: How can existing computers and information technologies assist in medical activities? Which components of the mathematical apparatus of informatics can be used for solving medical problems, and how and what activities of a physician are subject to algoritmization? The present time raises a new circle of questions centered around the basic one: How is the information system of the human organism structured and how does it function? This question and others form the basis of a new trend in medical informatics.

Concept graphics: a language for medical knowledge.

This paper makes a case for Concept Graphics, a novel form of medical knowledge representation. Concept Graphics are assemblies of icons each of which has a precise meaning. Individual icons are metaphors of the object or process they represent. Concept Graphics are analogs of pathological situations, their symptoms, signs and other relevant components necessary for a diagnosis. We propose three principal areas of application for Concept Graphics: medical education, medical records management and research based on medical records. Our earlier work in medical education showed a clear advantage in using Concept Graphics in parallel with text of equivalent information content, over text alone. A Concept Graphics based intelligent tutoring systems (ITS) is being developed. In the area of medical records management we are developing a system for the rapid identification of relevant records based on rapid visual screening. The Concept Graphics based system can reveal properties common to specific groups of records. As such the graphics are a research tool.

Designing web services in health information systems: from process to application level.

Service-oriented architectures (SOAs) and web service technologies have been proposed to respond to some central interoperability challenges of heterogeneous health information systems (HIS). We propose a model which we are using to define services and solutions for healthcare applications from the requirements in the healthcare processes. Focusing on the transition from the process level of the model to the application level, we also present some central design considerations, which can be used to guide the design of service-based interoperability. We illustrate these aspects with examples from our current work from the service-enabled HIS.

Computerized physiologic monitoring.

Computers can offer significant enhancement to the monitoring of the critically ill. Their value is derived from improved vigilance, better charting, and an opportunity to assess practitioner compliance with unit protocols. However, their true value can only be attained when they are integrated into a total information system.

[IT safety in medical networks--current problems and approach to solutions].

Designers and users of medical networks have to face strong requirements for data protection and security. Professional discretion and data protection laws allow the transfer of or access to patient data only in a therapeutic context. These data should also be protected from the network provider. Patients should be safe from any harm by faulty data or buggy procedures. On the other hand the security of the most used software products gets worse and worse. The use of the internet endangers more and more the integrity of the user's computer. The security requirements can be met only through strict care in planning, building, and configuring the infrastructure. Some concrete recommendations and guiding principles can immediately be realized. If these recommendations are followed, the internet can be of immense value for health care.

Addressing information security training and awareness within the European healthcare community.

This paper discusses the need to promote information security issues within modern healthcare establishments and the consequent need for appropriate training and awareness initiatives. Security is an area of extreme significance in healthcare information systems but, whilst the need is generally recognised, many personnel are not familiar with even basic concepts and procedures. As such, adequate promotion of security through training and awareness initiatives is viewed as a vital first step. The paper highlights a series of basic factors that healthcare establishments (HCEs) should consider in setting up a training and awareness framework. The discussion then examines a number of ways in which relevant information may be disseminated to staff, including security guidelines, training seminars and world-wide web based services. The paper is largely based upon work that is currently being conducted as part of the Health Telematics ISHTAR (Implementing Secure Healthcare Telematics Applications in euRope) project.

Experiences with a new security standard for healthcare information systems.

This article describes the results of the implementation and demonstration of the Standard CEN ENV 12924 (Security Categorisation and Protection of Health Care Information Systems), that was performed as part of the ISIS/MEDSEC project of the EU. The categorisation scheme given in the standard was followed through for almost all information systems or sub-systems in the Leiden University Medical Centre. The status of the security measures was evaluated for ten systems; further implementation plans were then drawn up for these systems, and partly effectuated. Findings are reported, both on the present security level, and on the applicability of the standard (which in general was found to be very positive). In the course of this work, use was made of a database support tool, developed in an earlier EU project (SEISMED).
