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.

Managing and displaying different time granularities of clinical information.

We approach the need of representing by powerful graphical user-interface the granularity of the temporal clinical information. In this work we present some contributions, to suitably display such temporal clinical information. The graphical representation relies on a temporal clinical data model able to manage data having different granularities.

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.

Electronic patient records for homecare nursing.

Electronic patient records have been the subject of research by academic and business organizations for at least 25 years. Despite a notable lack of progress, the time for broad acceptance of the concept may well be near. Important driving forces include 1) the external pressures being placed on the health care industry to lower costs and to provide standardized care with measures of outcome; and 2) new computer and communications technologies that can support the evolving "continuum of care," including the needs of even the most highly mobile clinicians. Home care nurses are ideal candidates to be early adapters of electronic patient records because of the high degree of mobility in their profession, their front-line role in the new health care system, their lack of a support structure at the point of care, and the excessive nursing time spent on documentation. Successful systems will be based on consideration of the clinician's working environment and computer skills, the interaction between the patient and the clinician, and the need for a record capable of supporting the sophisticated requirements of managed care.

Evaluation of an interactive computer video tutorial on malignant melanoma.

We evaluated medical student reaction to a computer-assisted interactive tutorial on malignant melanoma, a pigmented skin cancer. The tutorial was programmed for use with IBM Infowindow Touchscreen systems which integrate full-color video images from laser videodisc with text and graphics from a personal computer. Second-year medical students at the Medical College of Virginia responded to a questionnaire and rated both the content and the process of learning with this method more highly than presentation of similar content from textbooks.

A multiprocessor architecture for medical image compression in a PACS environment.

We present a new multiprocessor architecture for medical image compression using digital signal processors. The system has been designed to be used in a NuBus-based workstation and to apply different image compression algorithms to medical images. The system has been tested with a full-frame cosine transform and bit allocation table on several imaging modalities ranging from ultrasound to magnetic resonance imaging. Results show that image quality is acceptable when the allocation tables are calculated for each specific image modality. Implementation of algorithms such as wavelet transforms and vector quantization which respond to the characteristics of each type of image is in progress.

Mediated realism and the representation of a health care controversy.

Psychologists have recently identified "situated cognition" as an important issue for educators across disciplines. Accordingly, instructional technologists have been working on ways to make classroom materials more true-to-life and affectively engaging. In this article I review a study designed to investigate the ways in which differing realism conditions (delivered through interactive video) influenced users' understanding of the issue of euthanasia and the case of Dax Cowart. Based on the study's findings, I raise the issue of a possible trade-off between traditional values of objectivity and authenticity.

Computer interaction: catheters.

A computer interaction session conducted during the 14th Annual Peritoneal Dialysis Conference in Orlando, Florida, on January 24, 1994, revealed the preferences and practices of 650-690 respondents voting on questions related to peritoneal catheters. Compared to the surveys conducted in 1987 and 1989, the most striking change was an increase in the use of catheters with the bent intramural segment, particularly the Swan neck catheter, and an increase in the use of catheters with the coiled intraperitoneal segment. The Tenckhoff catheter continued to be the most popular, although its use was decreasing. The remaining catheters were used in small numbers. The vast majority of nephrologists remain convinced of the superiority of double cuff catheters over single cuff ones, and the use of the former continued to exceed 70%. Essentially no change occurred in the method of catheter placement; surgical dissection (72.7%) remained the most popular implantation method. Surgeons were primarily responsible for catheter implantations (87.4% of votes). The use of prophylactic antibiotics prior to catheter implantation seems to be increasing. The majority of respondents did not consider a Staphylococcus aureus nasal carrier status as important in the development of catheter-related infections, as indicated by the small number of centers where routine culture of nares was performed. The majority of institutions delayed ambulatory peritoneal dialysis after catheter implantation, but ambulatory peritoneal dialysis was started in some centers (5.7% of votes) in the immediate postimplantation period.
