Supercomputers open window of opportunity for nursing.
A window of opportunity was opened for nurse researchers with the High Performance Computing and Communications (HPCC) initiative in President Bush's 1992 fiscal-year budget. Nursing research moved into the high-performance computing environment through the University of Nevada Las Vegas/Cray Project for Nursing and Health Data Research (PNHDR). USing the CRAY YMP 2/216 supercomputer, the PNHDR established the validity of a supercomputer platform for nursing research. In addition, the research has identified a paradigm shift in statistical analysis, delineated actual and potential barriers to nursing research in a supercomputing environment, conceptualized a new branch of nursing science called Nurmetrics, and discovered new avenue for nursing research utilizing supercomputing tools.

Forecasting the need for physicians in the United States: the Health Resources and Services Administration's physician requirements model.
OBJECTIVE: The Health Resources and Services Administration's Bureau of Health Professions developed a demographic utilization-based model of physician specialty requirements to explore the consequences of a broad range of scenarios pertaining to the nation's health care delivery system on need for physicians. DATA SOURCE/STUDY SETTING: The model uses selected data primarily from the National Center for Health Statistics, the American Medical Association, and the U.S. Bureau of Census. Forecasts are national estimates. STUDY DESIGN: Current (1989) utilization rates for ambulatory and inpatient medical specialty services were obtained for the population according to age, gender, race/ethnicity, and insurance status. These rates are used to estimate specialty-specific total service utilization expressed in patient care minutes for future populations and converted to physician requirements by applying per-physician productivity estimates. DATA COLLECTION/EXTRACTION METHODS: Secondary data were analyzed and put into matrixes for use in the mainframe computer-based model. Several missing data points, e.g., for HMO-enrolled populations, were extrapolated from available data by the project's contractor. PRINCIPAL FINDINGS: The authors contend that the Bureau's demographic utilization model represents improvements over other data-driven methodologies that rely on staffing ratios and similar supply-determined bases for estimating requirements. The model's distinct utility rests in offering national-level physician specialty requirements forecasts.

Remote quantitation server for quality assurance in DNA ploidy analysis.
OBJECTIVE: To remotely test a stepwise framework of quality control measures, developed according to the 1997 European Society of Analytical Cellular Pathology consensus on diagnostic DNA image cytometry, in two series of measurements by means of the quantitation server EUROQUANT. STUDY DESIGN: In each of these series, 104 fine needle aspiration biopsies, imprints from breast cancer specimens and 28 rat liver imprints were measured twice at two different cytometry workstations. Further measurements on special rat liver specimens for evaluation of the stability of the machinery and of the preparation process were done at both workstations. Afterwards the measurement data from both machines were transferred to the quantitation server and analyzed automatically. Beside the classical DNA histograms, a set of further evaluations was performed to detect optical errors as well as inhomogeneities in the measurements. Running values for mean integrated optical density values, mean corrective factors and mean coefficients of variations of corrective factors were computed to control the stability of the entire methodology over time. RESULTS: The study demonstrated the preconditions and outcome of server-based quality control in DNA ploidy analysis. The results show that such a remote analysis is feasible and comparable to local DNA ploidy analysis. It is also demonstrated how quality control tests reflect the process performance of ploidy analysis at its different levels. CONCLUSION: Quality control must be an inherent part of the daily routine to allow a reliable diagnostic interpretation and ensure steadily high product quality.

Renewing information infrastructure at Hospital das Clínicas.
In this paper we describe the process of renewing the Informatics infrastructure of Sao Paulo University Medical School Hospital, a very complex environment. Our proposal consists of a change in the paradigm of Informatics and the use of Information Technology in the hospital. That change aims at making information available to the hospital, its managers, health care workers and patients. The paradigm change is reflected in every aspect of the new infrastructure: human resources, methods, and organizational structure, as we intend to demonstrate in this paper. This process is expected to be concluded by the end of this year, yielding benefits regarding costs, efficiency, and better patient care.

High performance computing for the human genome project.
Human Genome Analysis and Image Processing are part of the 'Grand Challenges' in High Performance Computing. The traditional mainframe has become insufficient for these applications in Biocomputing. New scalable parallel processor systems enter the marketplace with superior price/performance. The evaluation process of such a system by an application-oriented benchmark test suite is described. The system is integrated in the client/server structure of the Deutsches Krebsforschungszentrum where 'rightsizing' will eliminate the mainframe completely in the near future.

The use of personal computers in hospital infection control.
The storage, retrieval and analysis of hospital infection data is best performed by using computers. Many laboratory mainframe systems have infection control modules and there are some commercial programs for personal computers (PCs). An alternative is to use business and statistical PC software. Because of their large customer base these programs are reliable and easy to use yet extremely sophisticated and flexible, and they can be easily customized for use in infection control. Many combinations of software and hardware are available but the ones described here have been used successfully for several years at the Prince of Wales Hospital in Hong Kong.

Integrating the university medical center. Phase one: providing an information backbone.
UCLA School of Medicine represents a diverse computing community where the creation of each individual network has been driven by applications, price/performance and functionality. Indeed, the ability to connect to other computers has had no bearing on selection. Yet, there exists a need to seamlessly connect the individual networks to other minicomputers, mainframes and remote computers. We have created a school wide backbone network that will enable an individual from a single workstation to access a wide variety of services residing on any number of machines.

MediNet: Singapore's nationwide medical network.
MediNet is Singapore's nationwide computer network for the medical and health care community. This paper presents the case for MediNet and discusses the five high-priority applications which would be implemented by 1993. These 5 pilot applications focus on the processing of claims in hospital bills, electronic procurement of medical and surgical supplies, the transmission of notifications to government agencies, a national patient master index and access to local and foreign databases. MediNet will be able to link the computer systems of all participants in the healthcare delivery system. These include the Ministry of Health, Central Provident Fund (CPF) Board, government, restructured and private hospitals and general practice clinics. By connecting their computers (personal computers, minicomputers and mainframes) to MediNet, these organisations will be able to communicate, exchange data and access common applications on the network.

High-tech breakthrough DNA scanner for reading sequence and detecting gene mutation. A powerful 1 lb, 20 micron resolution, 16-bit personal scanner (PS) that scans 17" x 14" X-ray film in 48 s, with laser, UV and white light sources.
The 17" x 14" X-ray film, gels, and blots are widely used in DNA research. However, DNA laser scanners are costly and unaffordable for the majority of surveyed biotech scientists who need it. The high-tech breakthrough analytical personal scanner (PS) presented in this report is an inexpensive 1 lb hand-held scanner priced at 2-4% of the bulky and costly 30-95 lb conventional laser scanners. This PS scanner is affordable from an operation budget and biotechnologists, who originate most science breakthroughs, can acquire it to enhance their speed, accuracy, and productivity. Compared to conventional laser scanners that are currently available only through hard-to-get capital-equipment budgets, the new PS scanner offers improved spatial resolution of 20 microns, higher speed (scan up to 17" x 14" molecular X-ray film in 48 s), 1-32,768 gray levels (16-bits), student routines, versatility, and, most important, affordability. Its programs image the film, read DNA sequences automatically, and detect gene mutation. In parallel to the wide laboratory use of PC computers instead of mainframes, this PS scanner might become an integral part of a PC-PS powerful and cost-effective system where the PS performs the digital imaging and the PC acts on the data.

Computer applications in nursing continuing education.
Until recently, computers have been synonymous with mysterious, large mainframes requiring the services of computer wizards such as programmers and system analysts. The evolution of microcomputers and the availability of commercial (off the shelf) software programs has changed this concept and has put computer capabilities and benefits within the reach of any continuing education administrator. Implementing an automated information system demands the knowledge of the administrative process, an understanding of computer devices and the software that makes them work, and training skills, particularly those related to change theory. Armed with this knowledge, one can convert a manual information system to an electronic system using a fairly inexpensive microcomputer, commercial software programs, and existing personnel.
