Virtual Reality and Cognitive Assessment and Rehabilitation: The State of the Art
Authors: Rizzo Albert A.  , Buckwalter J. Galen
Published: February 2025

VR offers the potential to develop human testing and training environments that allow for the precise control of complex stimulus presentations in which human cognitive and functional performance can be accurately assessed and rehabilitated. However, basic feasibility issues need to be addressed in order for this technology to be reasonably and efficiently applied to the neuropsychological assessment (NA) and cognitive rehabilitation (CR) of persons with acquired brain injury and neurological disorders. This chapter will provide an introduction to the basic concepts of neuropsychological assessment and cognitive rehabilitation along with rationales for virtual reality's applicability in these complimentary fields. We review the relevant literature regarding theoretical and pragmatic issues for these applications, and provide a description of our ongoing work developing a mental rotation/spatial skills cognitive assessment and training system. References are provided in each section for further reading in each area reviewed.
Virtual Reality for the Treatment of Autism
Authors: Strickland Dorothy
Published: February 2025

Autism is a mental disorder which has received attention in several unrelated studies using virtual reality. One of the first attempts was to diagnose children with special needs at Tokyo University using a sandbox playing technique. Although operating the computer controls proved to be too difficult for the individuals with autism in the Tokyo study, research at the University of Nottingham, UK, is successful in using VR as a learning aid for children with a variety of disorders including autism. Both centers used flat screen computer systems with virtual scenes.

Authors: Privighitorita Ruxandra  , Sobottka Hans-Gerald  , Lordieck Wolfgang
Published: February 2025

Organization of hospital information systems that are currently in use is characterized by a multitude of simple, unfortunately less integrated components. For the integration of the already available as well as new components into a hospital information system, the “Comitee European de Normalisation” (CEN) proposed a basic “Conceptual Architectural Framework”. Based on the CEN proposal, in this paper we present first results of a case study in order to investigate the usability of the Distributed Healthcare Environment (DHE), as a standard architecture for hospital information systems. Another aim of this case study was to design an Order Entry and Result Reporting System and implement it by using DHE.
Improving Nursing Documentation to Include Outcomes of Care in Computerized Information Systems
Authors: McCormick K.A.
Published: February 2025

Oftentimes when models of information systems are developed, outcomes are either left out or described as an end product of treatment alone. However, in research demonstrating outcomes,evaluating whether outcomes are achieved can best be accomplished when the outcomes are integrated into the entire care process. This paper describes a model for nursing to consider when integrating outcomes during several components of nursing care delivery, and several nursing domains for achieving outcome of care.
Computer Literacy: Expected Learning Outcomes in Nursing Studies and the Reality
Authors: Saranto K.  , Leino-Kilpi H.
Published: February 2025

Information technology has been taught as part of nursing curricula for several years. With computer literacy now a basic requirement in clinical nursing practice, it is important to look more seriously at the standards and methods of teaching information technology at nursing colleges. In this study the objectives of teaching information technology and the content of information technology studies were evaluated by nurse educators (n=162) and by an expert panel (n=15). Nurse educators and the expert panel had more or less identical views on what those objectives should be. The quality and outcomes of information technology teaching in nurse education have never been measured in Finland before. In order to find out the consumers' point of view, student nurses were asked to assess their knowledge and skills in computer use. The student nurses (n=373) felt that they had a reasonable command of the theoretical knowledge in information technology. However, their keyboard skills were confined to the use of word processors.

Authors: Narita Y.  , Satou R.  , Takahashi H.  , Miura K.  , Takemoto Y.
Published: February 2025

We began to explore the subject of nursing information systems nine years ago. Since then, we have advocated a system that is intended to be used by nurses for their own purposes. We have developed an easy database management system (Native Data Base Management System, called NDBS hereafter) that is feasible to operate in the nursing situation. We also have developed an educational training system for information technology, which is appropriate for nursing students as well as for experienced nurses. Both systems have helped to greatly improve nursing services. In fact, nurses have already created several beneficial databases which are tailored to their nursing needs.

Nursing process documentation -Effects on Workload and Quality when using a Computer Program and a Key Word Model for Nursing Documentation
Authors: Sahlstedt S.  , Adolfsson H.  , Ehnfors M.  , Källström B.
Published: February 2025

In 1993 the federation of County Councils commissioned Spri to carry out a broadly based study aimed at investigating individualised patient care as described in the notes kept at various care units using computers to support documentation of the nursing process. The wards involved in the study represented various disciplines such as surgery, obstetrics, internal medicine, geriatrics and psychiatry. During the study period certain measures designed to improve the documentation were implemented i.e. a special computer program and structured nursing documentation following the VIPS-model. Interviews with staff at the units confirm that the introduction of computers, in combination with the structure of the VIPS-model and training in nursing documentation, has made changes possible to working procedures and brought greater goal orientation to the activity of care. The overall examination of the nursing entries in the patients' notes showed that the language has improved. The entries were to a greater extent expressed clearly and distinctly.

Authors: Kanai-Pak M.  , Hosoi R.  , Arai C.  , Ishii Y.  , Seki M.  , Kikuchi Y.  , Kabasawa K.  , Sato K.
Published: February 2025

In order to enhance students' active thinking, faculty members at International University of Health and Welfare developed the CAT (Computer Assisted Thinking) program. The CAT program is different from CAI (Computer Assisted Instruction), which mainly asks users to choose correct answers. Instead, the CAT program asks users to type in short sentences. There are two functions in the CAT program: one is to keep the students' action log each time they use the program and the other is to serve as medical dictionary. An analysis of the action log revealed that the students demonstrated little skill in inferential thinking. Their observations were very concrete. In order to help the students to develop their abstract thinking skills, we need to review our curriculum.
Data Mining: A Strategy for Knowledge Development and Structure In Nursing Practice
Authors: Eriksen L.R.  , Turley J.P.  , Denton D.  , Manning S.
Published: February 2025

Data mining is an emerging technique used more widely by the business world than the world of nursing and health care. However, this strategy can be helpful for improving the quality of decision making by clinicians and health care administrators. This paper addresses the concepts and techniques of data mining that could be useful for practicing nurses as well as nurse administrators. Data mining can be an important tool for the development of nursing knowledge and knowledge structures. An example of the use of the technique in an inpatient setting is provided and insights from the process are discussed.
Health-Related Outcomes Management: Moving Forward Standing Still
Authors: Shamian J.S.  , Nagle L.M.  , Catt M.A.
Published: February 2025

In response to increasing economic and political pressures, administrators and other health-care professionals have become increasingly concerned with health-related outcomes management. The categories of outcomes in health care have been identified within administrative, economic, and clinical realms. Great emphasis has been placed in the literature on the importance of measuring and using outcome data for decision making. Despite this emphasis, little progress has been made in either the science or the art of outcomes management. Furthermore, integrating the art and science into systematic processes for outcomes management has been done with limited success. This paper focuses on the state of outcome concepts, measurement, collection, and evaluation. Strategies will be offered to move the conceptualization and operationalization of outcomes management forward.

Authors: Snijders Mariëlle C.L.  , Bouten Carlijn V.C.  , van Putten Anton F.P.  , van Bronswijk Johanna E.M.H.
Published: February 2025

In patients with Chronic Obstructive Pulmonary Disease (COPD), daily physical functioning as quantified by energy expenditure, is limited by decreased ventilatory capacity and increased basal metabolic rate in relation to their physical capacity. Starting from the Dutch Health-Care situation, a measurement interpretation model is presented to quantify individual potential for independent living from energy expenditure, aerobic capacity and lung function. The interpretation model concerns only simple routine measurements. After further validation, this model will be used in predicting the clinical effects of environmental improvements.

The medical record is central to the management of patients. For people with a chronic disease which are treated by several physicians their many records, held at different locations, often pose a problem. Electronic patient records have been discussed for a long time. ByMedCard, a project funded by the Bavarian government in the framework of the ‘Bavaria Online’ programme and within the European Telematics project DIABCARD, implements an electronic patient record including chip card functionality. This article describes the set-up of the pilot test, the specification and implementation of the system and of the patient record and the envisaged security scheme. It demonstrates how the advantages of a portable medical record can be combined with other technologies.
Security Infrastructure of an Oncological Network Using Health Professional Cards
Authors: Blobel B.  , Pharow P.
Published: February 2025

Implementing the shared care paradigm, Health Care Establishments (HCE) communicate and co-operate also across institutional and organisational borders. The need for shared care, the corresponding communication and co-operation of underlying health information systems, the sensitivity of personal medical data, threats and solutions for data security are considered in the context of cancer patients' care. But there is also a data security need from the health professionals' (HP) point of view. The appropriate solution for provision of the required level of data security based on cryptographic algorithms is the implementation of a security infrastructure using health professional cards (HPC) and corresponding Trusted Third Party (TTP) services. In the framework of the regional Clinical Cancer Register Magdeburg/Saxony-Anhalt, both the organisational and technological requirements and the appropriate implementation of HPC and TTP services providing communication security are demonstrated in detail. Step by step development and implementation of application security are discussed.

Authors: Rousu Jon S.  , Kohls Paul E.  , Kall Bruce  , Kelly Patrick J.
Published: February 2025

The term “frameless image-guided surgery” has become as well-known to surgeons as computerized tomography or operating room microscope over the past several years. The technoloies behind this new surgery option include robotic arms, infra-red camera arrays (1D and 2D), ultrasound, robotic microscopes and magnetic field digitizers. The authors have shown the magnetic field technology incorporated in the Regulus Navigator to be a viable, accurate surgeon's tool by first integrating a conventional framed device and magnetic field frameless device, then advancing to the frameless device alone.

The Virtual Instrumentation (VI) Laboratory Facilitates Customized On-Site Ergonomic Analysis of Minimally Invasive Surgery
Authors: Smith Warren D.  , Forkey Denise L.  , Berguer Ramon
Published: February 2025

Ergonomic studies are needed to understand and improve the visual and physical interface that minimally invasive surgery methods interpose between the surgeon and the operating field. We used the Virtual Instrumentation (VI) Laboratory of the Biomedical Engineering Program at California State University, Sacramento to develop a portable ergonomic analysis system to compare the physical workloads imposed on the surgeon by tradition open and laparoscopic surgery techniques. We used the system at a national surgery conference to measure electromyogram (EMG) activity from thumb and forearm muscles of volunteer subjects as they performed simulated surgical tasks using open and laparoscopic techniques. We found that EMG activity was significantly greater for the laparoscopic than for the open surgery technique, suggesting that the laparoscopic technique was more physically demanding. The portable ergonomic analysis VI system was quick to set up and convenient to use. We are using the rapid prototyping and modular design capabilities of the VI Lab to develop additional ergonomic analysis VI systems.
A Non-Intrusive Display Technique for Providing Real-Time Data Within a Surgeons Critical Area of Interest
Authors: Parsons James  , Rolland Jannick P.
Published: February 2025

Modern surgeons have at their disposal a vast array of advanced technological data dissemination devices. The ring of high resolution monitors circling the typical operating area to display pre-operative and real-time patient data is esteemly supportive. The drawback, however. is that such displays require the surgeons to frequently shift their head and gaze away from the principle field of interest. We describe a new display technique that provides surgeons with a lightweight, wearable display surface that permits localization of medical data of main interest near the field of operation with minimal head and gaze movements.
DEVELOPMENT OF THE FORCE-FEEDBACK MODEL FOR AN EPIDURAL NEEDLE INSERTION SIMULATOR
Authors: Hiemenz Leslie  , Stredney Don  , Schmalbrock Petra
Published: February 2025

The Ohio Supercomputer Center and the Department of Anesthesiology at the OSU Medical Center have developed a computer-based simulation system for use in training anesthesiology residents in the technique of placing a needle for an epidural block. Although the simulator has been well regarded, the fidelity of the haptic feedback is limited because it is based on subjective expert-user evaluation and not on objective model-based or data based empirical methods. Only a single degree of freedom for force-feedback is required. However, the simulation must be able to accurately portray the force required to puncture each layer of tissue in order to feel realistic.
Virtual Jaw: A 3D Simulation for Computer Assisted Surgery and Education
Authors: Weingärtner Tim  , Haßfeld Stefan  , Dillmann Rüdiger
Published: February 2025

The jaw is one of the most complex joints in the human body. Its sliding and gliding movements are difficult to understand. Therefore, up to now there exist only mechanical simulations. But there is a strong need for a computer model of the jaw - the virtual jaw - to support physicians and surgeons in diagnoses and preoperative planning. During the preoperative planning of craniofacial operations for example, individual patient data has to be examined and the the operation has to be simulated. In the education of physicians such a simulation system gives a much better understanding of the anatomy and functionality of the jaw than static images in text books do. The paper presents a 3D simulation of the human mastication apparatus which can be used for the preoperative planning of craniofacial surgeries as well as the education of dentists and surgeons. It consists of three interacting components: A kinematic model which defines the constraints of the articulation, a model for the mastication muscles and a 3D graphical interface.

Web-based Segmentation and Display of Three-dimensional Radiologic Image Data
Authors: Silverstein Jonathan  , Rubenstein Jason  , Millman Alan  , Panko Walter
Published: February 2025

In many clinical circumstances, viewing sequential radiological image data as three-dimensional models is proving beneficial. However, designing customized computer-generated radiological models is beyond the scope of most physicians, due to specialized hardware and software requirements. We have created a simple method for Internet users to remotely construct and locally display three-dimensional radiological models using only a standard web browser. Rapid model construction is achieved by distributing the hardware intensive steps to a remote server. Once created, the model is automatically displayed on the requesting browser and is accessible to multiple geographically distributed users. Implementation of our server software on large scale systems could be of great service to the worldwide medical community.

The Information Needs of Health Agency Board Members: A Health Information System Challenge
Authors: Lynn Zelmer A.C.  , Zelmer Amy E.
Published: February 2025

Most hospitals and health agencies in developed countries, whether in the private or public sector, have ‘advisory committees’ or ‘boards ofmanagement’. Members of these bodies have significant responsibilities for the management of their organisations, but usually serve on these bodies on a part-time and voluntary basis. They may or may not have specific expertise in health care or management but are often selected because they are representative of parts of the community, are members of relevant organisations (medical bodies or, perhaps, staff unions) or belong to the correct political party.

A Signal Analysis Method for Retinal Image Velocity Computation of Vestibular-Ocular Reflex Eye Movement Investigations
Authors: Juhola Martti
Published: February 2025

The vestibulo-ocular reflex preserves clear vision when the subject's head is moving rapidly. These eye movements are measured in order to investigate equilibrium diseases and disorders in otoneurology. The retinal image velocity is calculated to be a difference signal between the head movement velocity and the eye movement velocity. The eye movement position signal as well as the head movement position signal of the subject are concurrently measured when the subject is asked to move his head according to a stimulus and his gaze is fixated to a target. Eye movements are electro-oculographically recorded and head movements with a potentiometer. Tests performed to both patients of an equilibrium laboratory and normals exemplify that the method is applicable to indicate some otoneurological diseases.
Information Overload: Opportunities and Challenges for the GP's Desktop
Authors: Noone Joe  , Warren James  , Brittain Michael
Published: February 2025

Recent developments in health data networks, the health sector and information systems, have created an overload of information available to the General Practitioner. The implementation of viable Health Data Networks within hospitals and subsequent connection to the GP's desktop PC enables increased access to patient records, decision-support and communication with experts around the world. To address the high usage of expensive health services and lengthy waiting lists health services around the world are embracing programs such as Community, Coordinated, Shared and Managed care. This focus on coordination of care and increased emphasis on evidenced-based medicine is greatly enhanced through the advent of viable health data networks. Other resources such as databases best-practice guidelines, the web, email, telemedicine and a range of commercial programs that provide further services has created an overload of resources available to the GP. Current human-computer interface guidelines are not adequate for prescribing design solutions to deal with the information overload facing GPs. The challenge for the near future is to present the vast array of information sources to the GP in an acceptable and useable information system interface. Part of the solution may revolve around the development of standards for Electronic Health Record systems for GPs, as is being done currently in Australia; but we suspect that less mainstream interface technologies will be required to exploit the wealth of available healthcare information.

Published: February 2025

In order to determine whether a super high definition (SHD) image running at a series of 2048 resolution x 2048 line x 60 frame/sec was capable of telemedicine, we established a filing system for medical images and two experiments for transmission of high quality images were performed. All images of various types, produced from one case of ischemic heart disease were digitized and registered into the filing system. Images consisted of plain chest x-ray, electrocardiogram, ultrasound cardiogram, cardiac scintigram, coronary angiogram, left ventriculogram and so on. All images were animated and totaled a number of 243. We prepared a graphic user interface (GUI) for image retrieval based on the medical events and modalities. Twenty one cardiac specialists evaluated quality of the SHD images to be somewhat poor compared to the original pictures but sufficient for making diagnoses, and effective as a tool for teaching and case study purposes. The system capability of simultaneously displaying several animated images was especially deemed effective in grasping comprehension of diagnosis. Efficient input methods and creating capacity of filing all produced images are future issue. Using B-ISDN network, the SHD file was prefetched to the servers at Kyoto University Hospital andBBCC (Bradband ISDN Businness chance & Culture Creation) laboratory as an telemedicine experiment. Simultaneous video conference system, the control of image retrieval and pointing function made the teleconfernce successful in terms of high quality of medical images, quick response time and interactive data exchange.

In this paper we present a class of time series distance measures based on the difference of their cepstral transformations. We emphasise the convenience of the proposed distance measure in the cases when the time series can be treated as output of a linear system driven with a quasi-periodic stochastic signals. In order to illustrate the cepstral time series distance measure we applied them in cluster and multidimensional scaling analysis of daily hormonal secretion fluctuation series taken from a group of patients before and after surgery.
Population Size and Quality in Genetics-Based Rule Learning from Medical Data
Authors: Laurikkala Jorma  , Juhola Martti
Published: February 2025

Population size and quality are parameters which control the performance of genetic algorithms. We researched these parameters in a genetic-based machine learning system Galactica which was used to discover the differential diagnostic rules for female urinary incontinence from case data. The performance of the system was measured with on-line and off-line criteria. Surprisingly, randomly generated small populations (30 and 70 rules) did not promote the best on-line performance as earlier results suggested. Probable explanation is the lack of diversity in initial populations. The seeding of population with positive learning examples was used to obtain more divergent populations. As expected, the seeding increased the on-line performance of small populations. The results are mainly in accord with the earlier results indicating that large randomly generated populations (150 rules) lead to the better off-line performance. Again, the seeding of small populations was successful producing even the better off-line performance than a large population. In conclusion, the seeding allowed the small populations to converge to good rules in relatively short period of time.

Published: February 2025

The University Medical Information Network (UMIN), established in 1989, is a network service organization for national university hospitals in Japan. It has provided various medical information services to medical professionals, including database, electronic mail, and news services. Although its initial network was constructed as a closed network using Nl protocol, it now adopts TCP/IP protocol and is open to other medical professionals via the Internet. The next UMIN network system is planned to be constructed as a secure virtual closed network on the Internet, using cipher technology, and to provide secure information services to national university hospitals via the closed network, and to other medical professionals via the Internet. User friendly interface and flexible system development were made possible by adopting TCP/IP, and the number of users dramatically increased accordingly. However, the database, software design, and human organizations developed in the Nl era have now proven to be ofgreat value, and contribute to todayis flourishing state of the UMIN.

Published: February 2025

Compositionality is the ability of a Vocabulary System to record non-atomic strings. In this manuscript we define the types of composition, which can occur. We will then propose methods for both server based and client-based composition. We will differentiate the terms Pre-Coordination, Post-Coordination, and User-Directed Coordination. A simple grammar for the recording of terms with concept level identification will be presented, with examples from the Unified Medical Language System's (UMLS) Metathesaurus. We present an implementation of a Window's NT™based client application and a remote Internet Based Vocabulary Server, which makes use of this method of compositionality. Finally we will suggest a research agenda which we believe is necessary to move forward toward a more complete understanding of compositionality. This work has the promise of paving the way toward a robust and complete Problem List Entry Tool.
Vision of an ‘automated’ hospital information system
Authors: Balkányi László  , Lakner Géza
Published: February 2025

This paper tries to describe a coherent vision of a possible next generation of HIS that rethinks how and what for computing is used in hospitals. Current systems, organized mainly around the ‘database’ and the ‘communication’ paradigm help the data processing to a great extent. At the same time they cannot be accepted as ‘automated’ systems, as handling of information is done mostly by end- users, i e. by human actors. Emerging methods enabling automated information handling are the following: integrated handling of different media, seamless communication among different systems, alternative input-output devices, tools for pro-active information handling These technologies should be grouped to two main branches: technical advances in data handling and theoretical advances in knowledge handling. The advances in knowledge handling are really important: tools based on that can take over routine information handling tasks from human end users. To discuss automation in HIS it is useful to understand the process of information handling in general within the hospital. A suggested multidimensional information space, where information objects are gathered mainly along two axes, the ‘patient axis’ and the ‘management’ axis might be of help. Combinations of selected dimensions resulted in a space of an estimated 2294082 possible information handling situation types in an earlier publication. Automation of information handling tasks can be derived from this model. The authors suggest to automate certain tasks done usually by active actors of the information handling situation space. Software agents working ‘on their own’ are known entities in HIS systems. Two components are needed for automation:
OOMM - Object-Oriented Matrix Modelling: an Instrument for the Integration of the Brasilia Regional Health Information System
Authors: Cammarota Márcio  , Huppes Vilson  , Gaia Sérgio  , Degoulet Patrice
Published: February 2025

The development of Health Information Systems is widely determined by the establishment of the underlying information models. An Object-Oriented Matrix Model (OOMM) is described which target is to facilitate the integration of the overall health system. The model is based on information modules named micro-databases that are structured in a three-dimensional network: planning, health structures and information systems. The modelling tool has been developed as a layer on top of a relational database system. A visual browser facilitates the development and maintenance of the information model. The modelling approach has been applied to the Brasilia University Hospital since 1991. The extension of the modelling approach to the Brasilia regional health system is considered.
Why Good Hospitals Get Bad Computing
Authors: Bleich Howard L.
Published: February 2025

American Hospitals spend a lot of money for computing, but physicians and nurses are dissatisfied with the computing that they receive. No one is at fault. Rather, each person, acting in his or her best interest, unwittingly conspires to produce the unfavorable result. Until hospitals make major and fundamental changes in the way they purchase and manage computing, they will continue to spend large sums without commensurate return.

Reality and subjective perception of the reality are two different issues. The factors that influence the reality have to be taken into account to understand that environment changes require re-training on reality perception.
Information system for clinical resource management in a regional setting
Authors: Lehtonen Olli-Pekka  , Räihä Ismo  , Wilson Kenneth
Published: February 2025

The Hospital District of Varsinais-Suomi consists of five hospitals for non-psychiatric diseases to deliver specialised health care for the population of 440000 inhabitants in South-western Finland. We have applied an open regional information system to aid clinical resource management in such a complex expert organisation. The main areas of application have been assessment of inpatient care usage in different communities and in different diagnosis-related-groups (DRG), measurement of length of hospital stay in different DRGs and comparison of DRG unit weight costs of different hospitals. The open structure of the data base and its distribution to all parties of health care professionals has resulted in mutual decisions on structural changes and increased cost containment activities.
Health and Nursing Informatics Education
Authors: Mantas John
Published: February 2025

In Europe, coordinated activities in healthcare informatics education started in the late 1980's with the establishment of European Courses in Health Telematics. At the same time the European Commission foresaw the need for spreading the knowledge of IT in the Healthcare Sector. Therefore the EC, since then, have supported the initiatives that aim to create awareness, stimulate diffusion, educate and train the users (healthcare professionals) in the application of Information Technology to the Healthcare Sector. Such initiatives are the NIGHTINGALE project, which is an essential project in the planning and implementation of strategy in training the Nursing profession in using and applying healthcare information systems, the IT EDUCTRA project, which is a very practical project in the field of the education and training of the Healthcare Professionals in Information Technologies, and the ERASMUS Master's Course, which is aiming at giving those working, or intending to work in the health service and related activities a broad, advanced postgraduate education in Health Informatics.
Convincing Cases: Important Component of User Acceptance
