Microcomputer-assisted transmission of disaster data by cellular telephone.

Voice communication of information during disasters is often inadequate. In particular, simultaneous transmission by multiple callers on the same frequency can result in blocked transmissions and miscommunications. In contrast, nonvoice transmission of data requires less time than does voice communication of the same data, and may be more accurate. We conducted a pilot study to test the feasibility of a microcomputer assisted communication (MAC) network linking the disaster scene and the command hospital. The radio chosen to transmit data from the field disaster site to the command hospital was a cellular telephone connected to the microcomputer by modem. Typed communications between the microcomputer operators enabled dialogue between the disaster site and the hospitals. A computer program using commercially available software (Symphony by Lotus, Inc.) was written to allow for data entry, data transmission, and reports. Patient data, including age, sex, severity of injury, identification number, major injuries, and hospital destination were successfully transmitted from the disaster site command post to the command hospital. This pilot test demonstrated the potential applicability of MAC for facilitating transmission of patient data during a disaster.

Automated continuing education and patient education.

This article discusses the use of a computer network to provide instruction for health care providers and patients and provides examples of screens from the educational modules developed for the project. The continuing nursing education and patient education modules were developed as a portion of the components for KARENET (Kellogg Affiliated Remote Environments Network), linking rural Morton, Texas, and the Health Sciences Center at Lubbock, Texas. Both health care providers and patient participants are benefiting from knowledge provided by the methodology of CAI/CMI provided by the network.

Simulation of patient flow in a picture archival and communications system network.

As hospital radiology departments expand their use of digitally formatted imaging devices, these machines will be connected in local area networks called Picture Archival and Communications Systems (PACS). The purpose of this paper is to demonstrate the use of computer simulation to analyze the process of patients using a PACS. The flexibility of using simulation on a proposed PACS is shown, starting with the description of a basic model. Different machine networks are run and the results compared. Simulation modeling provides a valuable tool to hospital and department administrators in detecting possible problem areas which may occur with proposed PACS configurations under assumed patient loads.

NeuroSIG: the computer network of the Congress of Neurological Surgeons.

A sophisticated computer network has been developed specifically for use by the Congress of Neurological Surgeons. This network provides a variety of communication and information features. These include public and private message transmission, teleconferencing, numerous data libraries, programs that may be downloaded and executed on the user's own computer, high resolution color graphics image transmission, an extensive neurosurgical database, and extensive on-line "help" features. The system can be accessed using almost any personal computer and a telephone modem.

[Informatics in the School of Medicine of the University of Chile. II. The school network and access to data bases].

Projects on informatics at the School of Medicine of the University of Chile are being brought about in accordance with both its institutional goals and present trends in technology. Prominent among the latter are the widespread distribution of autonomous processing power represented by low-cost computers and the ease of communication at local and worldwide levels. Our main project has been the design and start of a computer network that integrates the School's Departments and the geographically dispersed teaching hospitals. The principal services provided by the network are local and international electronic mail, access to data bases, and emulation of mainframe terminals (eg, to run remotely a mainframe's statistics software). Automated bibliographic search has been made available both through remote access to Medline data base and through local usage of compact disc (CD-ROM) versions. Since our network is open, it should become a forceful mean of assisting and integrating the biomedical community throughout the country.

Hospital-wide distribution of nuclear medicine studies through a broadband digital network.

Nuclear medicine provides a good environment for the evaluation of picture archiving and communication systems (PACS) because of the relatively small quantity of digital data that are generated, leading to reduced requirements for storage, display, and transmission compared with those found in radiology. The PACS in nuclear medicine is characterized by use of a single computer as a central storage, display, and analysis node. Images are acquired with use of small, low-cost computers attached to each camera. This network configuration offers advantages of convenience, but with great reliance on a single computer. A campus-wide picture network is under development at Washington University employing broadband cable television technology supplemented by baseband Ethernet (Digital Equipment Corp, Maynard, MA) components. All areas of diagnostic radiology and nuclear medicine are connected via a PACS testbed project. A radiology information system, supporting over 250 terminals, provides digital tracking of patients and report generation and retrieval. A new image workstation is under development in conjunction with Digital Equipment Corp. This system will permit display in multiple windows of report information and images from various modalities. A lung scan demonstration project is now beginning that is designed to test the value of a PACS in nuclear medicine. Digitally acquired chest radiographs will be displayed on an image workstation in nuclear medicine along with digital ventilation and perfusion lung scans. It is hoped that time-consuming logistic bottlenecks now encountered in lung scan interpretation will be reduced.

Analog-to-digital clinical data collection on networked workstations with graphic user interface.

An innovative respiratory examination system has been developed that combines physiological response measurement, real-time graphic displays, user-driven operating sequences, and networked file archiving and review into a scientific research and clinical diagnosis tool. This newly constructed computer network is being used to enhance the research center's ability to perform patient pulmonary function examinations. Respiratory data are simultaneously acquired and graphically presented during patient breathing maneuvers and rapidly transformed into graphic and numeric reports, suitable for statistical analysis or database access. The environment consists of the hardware (Macintosh computer, MacADIOS converters, analog amplifiers), the software (HyperCard v2.0, HyperTalk, XCMDs), and the network (AppleTalk, fileservers, printers) as building blocks for data acquisition, analysis, editing, and storage. System operation modules include: Calibration, Examination, Reports, On-line Help Library, Graphic/Data Editing, and Network Storage.
