Meta-manager: a requirements analysis. (25/7649)

The digital imaging network-picture-archiving and communications system (DIN-PACS) will be implemented in ten sites within the Great Plains Regional Medical Command (GPRMC). This network of PACS and teleradiology technology over a shared T1 network has opened the door for round the clock radiology coverage of all sites. However, the concept of a virtual radiology environment poses new issues for military medicine. A new workflow management system must be developed. This workflow management system will allow us to efficiently resolve these issues including quality of care, availability, severe capitation, and quality of the workforce. The design process of this management system must employ existing technology, operate over various telecommunication networks and protocols, be independent of platform operating systems, be flexible and scaleable, and involve the end user at the outset in the design process for which it is developed. Using the unified modeling language (UML), the specifications for this new business management system were created in concert between the University of Arizona and the GPRMC. These specifications detail a management system operating through a common object request brokered architecture (CORBA) environment. In this presentation, we characterize the Meta-Manager management system including aspects of intelligence, interfacility routing, fail-safe operations, and expected improvements in patient care and efficiency.  (+info)

Developing a framework for worldwide image communication. (26/7649)

The increasing mobility of the population and frequent changes in healthcare coverage, in both the government and private sectors, require integration of medical records not only longitudinally, but also across a variety of healthcare providers. Early in 1998, the federal government decided to solve this problem by constructing a framework for access to medical records by all of the government's health care facilities, called the Government Computer-Based Patient Record (GCPR). The government consortium chose a proposal by Litton PRC, a partnership of 11 companies with complementary areas of expertise. The framework is based on open systems, which use publicly available standards, and includes a Master Patient Information Locator that allows access to medical information from remote facilities, based on creating a unique identifier for each and every individual patient. PRC will use the Digital Imaging and Communications in Medicine (DICOM) imaging standard for radiology, supplemented by Health Level Seven (HL7).  (+info)

Integrated radiology information system, picture archiving and communications system, and teleradiology--workflow-driven and future-proof. (27/7649)

The proliferation of integrated radiology information system/picture archiving and communication system (RIS/PACS) and teleradiology has been slow because of two concerns: usability and economic return. A major dissatisfaction on the usability issue is that contemporary systems are not intelligent enough to support the logical workflow of radiologists. We propose to better understand the algorithms underlying the radiologists' reading process, and then embed this intelligence into the software program so that radiologists can interact with the system with less conscious effort. Regarding economic return issues, people are looking for insurance against obsolescence in order to protect their investments. We propose to future-proof a system by sticking to the following principles: compliance to industry standards, commercial off-the-shelf (COTS) components, and modularity. An integrated RIS/PACS and teleradiology system designed to be workflow-driven and future-proof is being developed at Texas Tech University Health Sciences Center.  (+info)

Interactive web-based radiology teaching file. (28/7649)

This multimedia radiology teaching file was developed for medical students, residents, physicians, and researchers to present teaching components related to clinical studies. Patient studies are used to create teaching cases, user can also create lecture series and custom presentations (catalogs) by linking related text and images. The user is able to make and preserve his/her own notes related to reviewed information. From the computer workstation, the user can perform search our case library by American College of Radiology (ACR) codes, keywords, modalities, or text. Results are presented in custom pages and include text lists, thumbnails lists, rescaled images, and full-size images. Text can be easily printed in custom format or exported to an ASCI file. To preserve the privacy of the student, access to our database is granted to the web browser by log-in panel. Image and text can be imported from Digital Imaging and Communications in Medicine (DICOM)-compatible devices or entered by using web forms. In conclusion, we developed a multifunctional interactive teaching environment accessible for multiplatform internet users.  (+info)

Evaluating a picture archiving and communications system workstation. (29/7649)

An efficient environment for picture archiving and communications systems (PACS) in the radiology department and throughout a medical practice requires good hardware, good software, and integration of the information sources that exist in a radiology department and institution. This tutorial will describe some of the considerations in evaluating a PACS workstation, with a view to the hardware requirements, user interface designs, and integration with the information systems.  (+info)

Use of bar code readers and programmable keypads to improve the speed and accuracy of manual data entry in the clinical microbiology laboratory: experience of two laboratories. (30/7649)

AIM: To assess the effect of the use of bar code readers and programmable keypads for entry of specimen details and results in two microbiology laboratories. METHODS: The solutions selected in each laboratory are described. The benefits resulting from the implementation were measured in two ways. The speed of data entry and error reduction were measured by observation. A questionnaire was completed by users of bar codes. RESULTS: There were savings in time and in reduced data entry errors. Average time to enter a report by keyboard was 21.1 s v 14.1 s for bar coded results entry. There were no observed errors with the bar code readers but 55 errors with keystroke entries. The laboratory staff of all grades found the system fast, easy to use, and less stressful than conventional keyboard entry. CONCLUSIONS: Indirect time savings should accrue from the observed reduction in incorrectly entered data. Any microbiology laboratory seeking to improve the accuracy and efficiency of data entry into their laboratory information systems should consider the adoption of this technology which can be readily interfaced to existing terminals.  (+info)

Computing for the next millennium. (31/7649)

Computer technology has changed our lives, even that of physicians. In a few years time, a physician can expect to have a new tool by the bedside: a hand-held computer small enough to put into a pocket and powerful enough for all everyday activities, including highly specialized and sophisticated activities such as prevention of adverse drug reactions. The Croatian Academic and Research Network (CARNet) was crucial in bringing the benefits of the information technology to the Croatian scientists. At the Split University School of Medicine, we started the Virtual Medical School project, which now also includes the Mostar University School of Medicine in neighboring Bosnia and Herzegovina. Virtual Medical School aims to promote free dissemination of medical knowledge by creating medical education network as a gateway to the Internet for health care professionals.  (+info)

Making sense of the electronic resource marketplace: trends in health-related electronic resources. (32/7649)

Changes in the practice of medicine and technological developments offer librarians unprecedented opportunities to select and organize electronic resources, use the Web to deliver content throughout the organization, and improve knowledge at the point of need. The confusing array of available products, access routes, and pricing plans makes it difficult to anticipate the needs of users, identify the top resources, budget effectively, make sound collection management decisions, and organize the resources effectively and seamlessly. The electronic resource marketplace requires much vigilance, considerable patience, and continuous evaluation. There are several strategies that librarians can employ to stay ahead of the electronic resource curve, including taking advantage of free trials from publishers; marketing free trials and involving users in evaluating new products; watching and testing products marketed to the clientele; agreeing to beta test new products and services; working with aggregators or republishers; joining vendor advisory boards; benchmarking institutional resources against five to eight competitors; and forming or joining a consortium for group negotiating and purchasing. This article provides a brief snapshot of leading biomedical resources; showcases several libraries that have excelled in identifying, acquiring, and organizing electronic resources; and discusses strategies and trends of potential interest to biomedical librarians, especially those working in hospital settings.  (+info)
