An object-oriented tool for the generation and management of multimedia patient folders.

Computer-based patient folders are evolving from the simple reproduction of traditional paper documents toward active tools, able to support the whole diagnostic and therapeutic process. The advent of multimediality has given emphasys to the idea of computerized folder, i.e. a collection of heterogeneous kinds of documents pertaining different media. In this paper we present a tool implementing generation and management of multimedia patient folders showing its architecture and functionalities and the innovative interaction paradigms adopted. The tool realized allows medical users to choose the concepts desired in their target application and generates a customized patient folder management system by means of a friendly interface and without the need of a programming language. The system automatically created can be effectively employed for reporting and storing clinical cases.

Medical data capture and display: the importance of clinicians' workstation design.

The Department of Veterans Affairs is developing, testing and evaluating the benefits of physicians' workstations as an aid to medical data capture in an outpatient clinic setting. The physician's workstation uses a graphical user interface to aid the clinician in recording encounter data. Various input devices including keyboard, mouse, pen, voice, barcode reader, and tablet are available on the workstations, and user preferences will be examined. Access to general services such as electronic mail and reference databases is also available. The workstation provides a wide variety of patient specific data from the hospital information system, including image data. The single data collection process by the clinician will also provide data for the cost recovery process.

Multimedia clinical simulation based on patient records: authoring, user interface, pedagogy.

As an alternative to available computer-based clinical simulations that mimic patient encounters, we developed a clinical case simulation that more closely resembles the patient record. Our system, implemented in a Macintosh program called Short Rounds, features rapid and customized case authoring by editing a structured text file, a dynamic user interface that presents a case-specific screen layout, and a pedagogical model that is suitable for teaching third-year medical students. We believe this approach allows faculty members to create multimedia case simulations in shorter periods of time than in available clinical simulations.

A cooperative model for integration in a cardiology outpatient clinic.

With the increasing amount of digitally stored patient information, such as images and findings, the possibility and need arise for a system which is able to both store and display this information in a structured, user-friendly way. In the common situation where different information systems are used within one department, this means that the various information systems have to be integrated. However, integration requires more complex management of data, processes and windows. This management can be handled by a Workspace Manager, which controls inter-application tasks, and interaction with the user. Furthermore, this Workspace Manager supports the user with the definition of complex tasks such as collecting problem-related patient information from the various remote systems. In an outpatient clinic for cardiology this architecture is used to achieve cooperative integration of an open Computer Patient Record with a range of information-specific services.

The development of a client application for the collaborative social and medical services system.

This paper describes the design and implementation of a client application for the Baylor College of Medicine Teen Health Clinics. The application is the front end to the Collaborative Social and Medical Services System (CSMSS) under development by Baylor's Medical Informatics and Computing Research Program [8]. The application provides distributed access to an underlying object oriented database system. A process driven and patient centered design will provide staff members with a complete set of services, including forms for data entry and viewing, query, and access management to facilitate efficient and effective delivery of services. Role-specific interfaces will be supplied for clerks, nurses, nurse practitioners, physicians, and social workers. The client application is being designed using object oriented methodologies and technologies with the C++ programming language, and will operate within a Microsoft Windows operating environment utilizing Object Linking and Embedding for application interoperability.

Automated medical knowledge acquisition: a study of consistency.

Knowledge bases are more representative of the population of medical experts if they are constructed by a group of individuals, rather than one practitioner. However, one runs into problems with consistency when information is elicited from a group without a consistent format and terminology. This study examines the consistency of relatively unconstrained computer-elicited medical knowledge using the computer program, KSSO. The results of this study show that the group of ten general internists were somewhat consistent in the diagnoses they listed for a patient presenting with chest pain. They were much less consistent in the findings they listed to differentiate between the diagnoses they had listed. The mean number of subjects listing each diagnosis was 3.3 +/- 2.7 while the mean for findings was 2.0 +/- 1.5. The implications of these data are discussed.

Towards effective implementation of a pediatric asthma guideline: integration of decision support and clinical workflow support.

Successful local implementation of national guideline recommendations requires attention to factors that promote clinician compliance. Design of a computerized system is described that will implement recommendations from a recently published guideline for outpatient management of childhood asthma exacerbations. Logical analysis of the guideline shows that it is incomplete and contains several ambiguities that must be addressed before the guideline can be operationalized. Once the user-audience is defined guideline decision points are examined and a structured data entry system is devised. Support of clinicians' workflow is provided by an integrated capability for encounter documentation, dosage calculation, and prescription-writing. A pen-based, graphical interface represents an appropriate platform for implementation of the system because of its ease of use and portability.

Indexing guidelines: applications in use of pulmonary artery catheters and pressure ulcer prevention.

In a busy clinical environment, access to knowledge must be rapid and specific to the clinical query at hand. This requires indices which support easy navigation within a knowledge source. We have developed a computer-based tool for trouble-shooting pulmonary artery waveforms using a graphical index. Preliminary results of domain knowledge tests for a group of clinicians exposed to the system (N = 33) show a mean improvement on a 30-point test of 5.33 (p < 0.001) compared to a control group (N = 19) improvement of 0.47 (p = 0.61). Survey of the experimental group (N = 25) showed 84% (p = 0.001) found the system easy to use. We discuss lessons learned in indexing this domain area to computer-based indexing of guidelines for pressure ulcer prevention.

Interface for the documentation and compilation of a library of computer models in physiology.

A software interface for the documentation and compilation of a library of computer models in physiology was developed. The interface is an interactive program built within a word processing template in order to provide ease and flexibility of documentation. A model editor within the interface directs the model builder as to standardized requirements for incorporating models into the library and provides the user with an index to the levels of documentation. The interface and accompanying library are intended to facilitate model development, preservation and distribution and will be available for public use.

The role of object representation in the design of the intelligent radiology workstation.

The paper describes the design of the Intelligent Radiology Workstation (IRW) that is intended to handle heterogeneous radiologic data (text, image, video) and radiologic knowledge in such a way that it is easy to store, access, use, and repurpose. An object-based structure is used to combine the relational database, hybrid knowledge base, and hypermedia within a common framework. Functions such as data entry and retrieval, browsing, and intelligent processing of data are available in the single environment. IRW open architecture allows radiologic digital resources to be used for clinical practice, diagnosis support, education, and research.

Monitor-driven data visualization: SmartDisplay.

Exhaustive display of all available clinical data, particular in data-rich environments like the intensive care unit, can easily overwhelm the ability of clinicians to comprehend the clinical status and evolution of their patients and may reduce their ability to detect pathological trends in a reliable and timely manner. SmartDisplay is a system we have designed that restricts the data sets displayed to time-lines of those parameters that are relevant to the patient context and to the particular care provider. The relevance criteria are provided by monitoring programs which may range in complexity from simple threshold alarms to full-fledged diagnostic engines. SmartDisplay can specify which parameters to display and the time intervals during which they should be displayed.

Visualization and analysis of co-occurrence and cross-tabulation data in medical research.

Analyzing raw data can be prohibitively time consuming. A variety of graphical techniques have been developed to address this problem. Although graphical analysis can provide a simple yet comprehensive overview of a large dataset, often these techniques fail to capture the essence of data trends. In addition, the ability to easily query any component of the data subset frequently remains burdensome. In this paper, we present a general method to address these issues for cross-tabulation tables and provide examples of their use in medical research.

Nurses' experiences of a post-RN course by computer mediated conferencing: friendly users.

Students who had completed a post-RN university nursing course by computer mediated conferencing participated in a qualitative study examining their experience with this mode of delivery of distance education. All seven students reported that great difficulties with the technology at the beginning of the course caused them extreme frustration. However, despite the lack of user-friendliness of the technology, the students participated actively, functioned as a group, developed strong personal ties, and mastered the required content via the computer. These multiple-role women appreciated the ability to participate in discussion without the requirement of being at a specific place at a particular time. Having overcome the initial difficulties with the technology, all the students were enthusiastic about the method and would sign up for another computer mediated course.
