Multimedia in nursing and patient education.

Multimedia education or computer-based instruction is currently being used in both patient and nursing education for staff development, continuing education, general health information, and informed consent. It can be used to teach content, skills, and concepts, as well as to simulate situations. Multimedia may be incorporated as a part of other hospital systems to provide individualized patient education by using actual patient data. Multimedia as an instructional strategy has some definite advantages and disadvantages that can affect integration and use. It will be used more and more in the health care environment to provide consistent, accurate information to nurses and patients.

The virtual anatomy practical: a stereoscopic 3D interactive multimedia computer examination program.

Continuing advances in computer visualization and interface technologies have enabled development of "virtual reality" programs that allow users to perceive and to interact with objects in artificial three-dimensional environments. Such technologies were used to create an image database and program for administering a practical examination in human gross anatomy. Stereoscopic image pairs of prepared laboratory dissections were digitized from multiple views of the thorax, abdomen, pelvic region, and upper and lower extremities. For each view, the stereo pairs were interlaced into a single, field-sequential stereoscopic picture using an image processing program. The resulting color-corrected, interlaced image files were organized in a database stored on a large-capacity hard disk. Selected views were provided with structural identification pointers and letters (A and B). For each view, appropriate two-part examination questions were spoken by a human narrator, digitally recorded, and saved as universal audio format files on the archival hard disk. Images and digital narration were organized in an interactive multimedia program created with a high-level multimedia authoring system. At run-time, 24-bit color 3D images were displayed on a large-screen computer monitor and observed through liquid crystal shutter goggles. A 90-second interval timer and tone were provided to give student users a time limit for each question comparable to that of a conventional practical examination. Users could control the program and select regional "subexams" using a mouse and cursor to point-and-click on screen-level control words ("buttons").

Development of multimedia learning modules for teaching human anatomy: application to osteology and functional anatomy.

Computer-assisted learning (CAL) is growing quickly within academic programs. Although the anatomical commercial packages that are available for this learning have attractive advantages, they also have drawbacks: they are frequently not in the local language of the students, they do not perfectly answer the needs of the local academic program, and their cost is frequently more than students can afford. This study describes a relatively inexpensive method to create CAL tutorials, whose content can be fully customized to local academic needs in terms of both program and language. The study describes its use in creating multimedia learning modules (MLMs) about Osteology and joint kinematics. The pedagogical content in these modules was collected from objective experiments to give students the opportunity to access new scientific knowledge during their education. It can be replaced, as desired, by almost any content due to the flexibility of the production method. Each MLM consists of two complementary subelements: a multimedia theoretical lecture and a three-dimensional interactive laboratory. Such MLMs are in use at both the University of Brussels (ULB) and the National University of Rwanda (NUR). The development of this work was part of the VAKHUM project, and the pedagogical validation is currently being performed as part of the MULTIMOD project.

BETR North America: a regionally segmented multimedia contaminant fate model for North America.

We present the Berkeley-Trent North American contaminant fate model (BETR North America), a regionally segmented multimedia contaminant fate model based on the fugacity concept. The model is built on a framework that links contaminant fate models of individual regions, and is generally applicable to large, spatially heterogeneous areas. The North American environment is modeled as 24 ecological regions, within each region contaminant fate is described using a 7 compartment multimedia fugacity model including a vertically segmented atmosphere, freshwater, freshwater sediment, soil, coastal water and vegetation compartments. Inter-regional transport of contaminants in the atmosphere, freshwater and coastal water is described using a database of hydrological and meteorological data compiled with Geographical Information Systems (GIS) techniques. Steady-state and dynamic solutions to the 168 mass balance equations that make up the linked model for North America are discussed, and an illustrative case study of toxaphene transport from the southern United States to the Great Lakes Basin is presented. Regionally segmented models such as BETR North America can provide a critical link between evaluative models of long-range transport potential and contaminant concentrations observed in remote regions. The continent-scale mass balance calculated by the model provides a sound basis for evaluating long-range transport potential of organic pollutants, and formulation of continent-scale management and regulatory strategies for chemicals.

A multimedia database system for thermal ablation therapy of brain tumors.

A prototype multimedia medical database is described for supporting thermal ablation therapy of brain tumors. Its design is motivated by the major need to manage and access multimedia information on the progress and reaction of tumors to various therapy protocols. The database links images to patient data in a way that permits the use to view and query medical information using alphanumeric, temporal, and feature-based predicates. Visualization programs permit the user to view or annotate the query results in various ways. These results support the wide variety of data types and presentation methods required by neuroradiologists to manage thermal ablation therapy data. The database satisfactorily meets the requirements defined by thermal ablation therapy. A similar approach is being undertaken for supporting different therapies of other types of tumors, thus showing the generality of our approach.

[Multimedia preoperative patient information].

Due to heavy workloads and shortage of staff, doctors often find it difficult to explain operations to their patients with the legally required detail and timing (in Germany, 24 h preop). This is however mandatory for obtaining informed consent. We developed a computer program that generates films explaining 24 common orthopedic operations and blood transfusion. They explain the operation, early postoperative phase, and benefits and risks to the patient. At our clinic, this program is used in daily routine and precedes the actual doctor-patient conversation for informed consent. We asked 300 patients about their satisfaction with the newly developed program. The multimedia presentation gives the patient more time, enough detail and clarity, and the chance to repeat parts of the film. For the doctor, it saves time. The time gap required in Germany between explanation and operation is thus easily adhered to. In case of legal problems, the film can be used for evidence. The use of this multimedia presentation to help in getting informed consent is improving workflow considerably.

A multimedia psychosocial support program for couples receiving infertility treatment: a feasibility study.

OBJECTIVE: To develop and test the feasibility of a theory-driven, psychosocial support CD-ROM prototype for couples in infertility treatment. DESIGN: Focus group meetings with reproductive health experts, semistructured interviews with infertility patients, and content analysis of an infertility message board to determine content domains of the CD-ROM. Usability and acceptance testing of prototype CD-ROM based on predetermined feasibility criteria. SETTING: Private offices and fertility centers. PATIENT(S): Expert panel of 5 reproductive health specialists; interviews with 62 individuals with infertility (35 women, 27 men); feasibility study with 12 patients and 12 experts in reproductive medicine and infertility support. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Product usability/acceptance test. RESULT(S): Participant feedback and content analysis informed the development of a prototype patient education CD-ROM that uses audio, video, interactive tasks, and personalized feedback. Over 80% of participants successfully completed usability tasks, and over 90% rated prototype satisfaction as "good" to "excellent." Some areas were noted for improvement in navigation and refinement in delivery of instructions. Results strongly indicate an interest in an infertility multimedia support tool. CONCLUSION(S): Multimedia methods may serve as an effective, innovative psychosocial intervention for infertility patients and overcome barriers of limited local access to educational and support services.

Developing a multimedia model of chemical dynamics in an urban area.

A multimedia model has been developed to account for the movement of semi-volatile organic compounds (SOCs) in an urban environment. The model, based on a Level III fugacity model of D. Mackay (Multimedia Environmental Models: The Fugacity Approach, Lewis Publishers, Boca Raton, FL, 1991), consists of six compartments: air, surface water, sediment, soil, vegetation, and an organic film that coats impervious surfaces. The latter is a newly identified compartment into which gas-phase SOCs partition and particle-phase SOCs are believed to be efficiently captured (M.L. Diamond, S.E. Gingrich, K. Fertuck, B.E. McCarry, G.A. Stern, B. Billeck, B. Grift, D. Brooker, T.D. Yager, Environ. Sci. Technol., 34 (2000a), 2900-2908). The model, parameterized for downtown Toronto, Ontario, Canada, and run with an illustrative emission rate for selected polycyclic aromatic hydrocarbons and homologues of polychlorinated dibenzodioxins, indicates that the film achieves the highest concentrations among media but that soils are the greatest sink for all but the least hydrophobic chemicals. The film "reflects" the more volatile chemicals into air, facilitates removal to surface waters by wash-off, and provides a surface on which photolytic degradation can occur. As such, the film is a transient sink that increases chemical mobility in urban areas by increasing air concentrations and the cycling of these compounds between air and urban surfaces and increasing water concentrations. Vegetation also accumulates SOCs, a portion of which is transferred to soil that reduces chemical mobility.

Fugacity superposition: a new approach to dynamic multimedia fate modeling.

The fugacities, concentrations, or inventories of pollutants in environmental compartments as determined by multimedia environmental fate models of the Mackay type can be superimposed on each other. This is true for both steady-state (level III) and dynamic (level IV) models. Any problem in multimedia fate models with linear, time-invariant transfer and transformation coefficients can be solved through a superposition of a set of n independent solutions to a set of coupled, homogeneous first-order differential equations, where n is the number of compartments in the model. For initial condition problems in dynamic models, the initial inventories can be separated, e.g. by a compartment. The solution is obtained by adding the single-compartment solutions. For time-varying emissions, a convolution integral is used to superimpose solutions. The advantage of this approach is that the differential equations have to be solved only once. No numeric integration is required. Alternatively, the dynamic model can be simplified to algebraic equations using the Laplace transform. For time-varying emissions, the Laplace transform of the model equations is simply multiplied with the Laplace transform of the emission profile. It is also shown that the time-integrated inventories of the initial conditions problems are the same as the inventories in the steady-state problem. This implies that important properties of pollutants such as potential dose, persistence, and characteristic travel distance can be derived from the steady state.

CARDIOMEDIA: a communicable multimedia medical record on Intranet and digital optical memory card.

As part of French health reform, French physicians were computerised by the end of 1998. A specific Intranet network will be used to communicate medical data between the health professionals. The objectives of the CARDIOMEDIA project were to develop and evaluate the feasibility of a coronary multimedia data record stored on an optical card and communicable on Intranet within the hospital. Patients treated by angioplasty at the University Hospital of Rennes participated in the experiment. In general, patients are treated in the University Hospital and are followed up by another health care provider closer to their home. The patient leaves the University Hospital with his card, which is directly available elsewhere for emergency or for consultation. This approach is assumed to reduce the number of examinations and to offer a better patient follow-up. The CARDIOMEDIA card is a specialised record including various data types: text, images, image sequences of coronarography and ECG signals. For this purpose an optical card with its large memory is very convenient. We used the DICOM format for image exchange and management. It is combined with CARDIOMEDIA specific compressing software. For the multimedia record the HTML format and web Intranet method are chosen. This provides an intuitive interface which can combine various data types and helper applications like a DICOM image viewer.

Computerized, interactive, multimedia cognitive-behavioural program for anxiety and depression in general practice.

BACKGROUND: Cognitive-behavioural therapy (CBT) brings about significant clinical improvement in anxiety and depression, but therapists are in short supply. We report the first phase of a randomized controlled trial of an interactive multimedia program of cognitive-behavioural techniques, Beating the Blues (BtB), in the treatment of patients in general practice with anxiety, depression or mixed anxiety/depression. METHOD: One hundred and sixty-seven adults suffering from anxiety and/or depression and not receiving any form of psychological treatment or counselling were randomly allocated to receive, with or without medication, BtB or treatment as usual (TAU). Measures were taken on five occasions: prior to treatment, 2 months later, and at 1, 3 and 6 months follow-up using the Beck Depression Inventory, Beck Anxiety Inventory and Work and Social Adjustment Scale. RESULTS: Patients who received BtB showed significantly greater improvement in depression and anxiety compared to TAU by the end of treatment (2 months) and to 6 months follow-up. Symptom reduction was paralleled by improvement in work and social adjustment. There were no interactions of BtB with concomitant pharmacotherapy or duration of illness, but evidence, on the Beck Anxiety Inventory only, of interaction with primary care practice. Importantly, there was no interaction between the effects of BtB and baseline severity of depression, from which we conclude that the effects of the computer program are independent of starting level of depression. CONCLUSIONS: These results demonstrate that computerized interactive multimedia cognitive-behavioural techniques under minimal clinical supervision can bring about improvements in depression and anxiety, as well as in work and social adjustment, with and without pharmacotherapy and in patients with pre-treatment illness of durations greater or less than 6 months. Thus, our results indicate that wider dissemination of cognitive-behavioural techniques is possible for patients suffering from anxiety and/or depression.

Limitations of multimedia models for use in environmental decision making.

The United States currently is engaged in a complex, multi-billion dollar effort to cleanup a legacy of both privately- and federally-owned hazardous waste sites. Decisions regarding the best approach for remediation of these sites often are based on the analysis of potential risks to human health and the environment. A cornerstone of such analysis is the frequent use of computerized multimedia environmental transport models, to evaluate the large quantities of information necessary to understand the present and future implications of contamination at a site. One barrier to wide-spread use of this analytical procedure is the view that results obtained using computer models are highly dependent on user input, and therefore, subject to manipulation. It is widely recognized that for decisions to be both credible and implementable, the public must have confidence in both the scientific basis for judgments involved and the decision processes employed (NRC, 1983). Our purpose in this article is to overview the difficulties associated with application of multimedia models to real world problems and the contribution these models can make to technically sound estimates of exposure and risk.

Concept and realization of a multimedia program for veterinary physiology.

A multimedia program, a non-linear system which supplements the traditional, linear way of learning (e.g. with a text book), was developed. Non-linear systems allow the direct use of information in a free sequence. A problem of these systems is the danger that the reader becomes lost in detail. Therefore, a program was constructed which tries to combine the properties of linear and non-linear teaching systems. Student groups were continuously involved during all stages of the project. The program is organized in several levels. These are: (1) choice of chapters; (2) table of contents of one chapter; (3) summary; (4) text and (5) pictures, animations, simulations and video sequences. The program can be used in different ways. In the linear mode, the reader selects via action words different levels of the program. The user can read either only on the level of the summaries or on detailed information (text, pictures, simulations and videos). In the non-linear mode the user jumps via menu items or buttons to selected pictures, simulations or a searched term. In this way, more than 3500 screen pages are integrated into a multimedia program for veterinary physiology. The program is written in TOOLBOOK, and can be used on a personal computer with Windows 95 or higher.

Multimedia education in headache: the European Neurological Network.

The European Neurological Network is a European Economic Community supported project. The purpose of the project was to develop a multimedia educational tool for general practitioners in order to improve their management of sleep disorders, epilepsy and headache. The project involves approximately one hundred engineers and physicians from Belgium, Denmark, England, Finland, France, Germany, Italy, Portugal and Spain. This paper concerns the multimedia educational tool on headache. The system consists of five different modules, i.e. classification, clinical data, headache tutorial, diagnostic headache diary and nomenclature. It is possible to move between the modules both vertically and horizontally. The headache classification of the International Headache Society is provided in full text as a work of reference. This classification is used world wide and has been adopted by International Classification of Diseases 10 Neurological Adaptation (ICD-10 NA) and the World Health Organisation. The clinical data concentrate on migraine and tension-type headache, the two most common headache disorders, but data on familial hemiplegic migraine, cluster headache, drug-induced headache and secondary headaches are also available. The headache tutorial consists of case records that the user can test their diagnostic abilities on. The diagnostic headache diary is an expert system on headache diagnostics. It can be filled in during a consultation in order to provide the headache diagnosis or it can be printed and used by the headache patient to record headache attacks and medicine consumption. The nomenclature module provides an explanation of words and expressions used in the system.
