[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.

The pharmacy computer system at the New England Medical Center.

The pharmacy computer system developed and implemented at the New England Medical Center (NEMC) is described. The system was developed to improve the department's fiscal performance and operations. It operates on NEMC's large mainframe system and has the following components-order entry, unit dose/patient profile, i.v. admixture, and financial/management. The system was designed to interface with the admissions and census system and use the pharmacy department's drug data file. It accepts medication orders from pharmacy satellites and then processes the orders according to the requirements for the i.v. admixture or unit dose procedures. Financial data are collected as a routine part of all medication order processing. The system allows for the entry of multiple medication orders on one cathode ray tube (CRT) screen, thus facilitating order entry. The use of programmed system defaults is described. Order entry, dose selection, and patient profiles are displayed on a CRT. An active order list is printed once daily at midnight to serve as a back-up for the system. The computer system has had a positive impact on the department's operational, clinical, and management functions. Future enhancements of the NEMC system are discussed.

Star tech.

The mission? To sensibly go where many have gone before--into the realm of information technology, where applications often outnumber sound business reasons to use them. If you've never been, don't believe everything you hear. Mainframes may be useful after all, and even widespread technologies don't hold all the answers.

Design of clinical database management systems and associated software to facilitate medical statistical research.

Clinical databases are growing rapidly. The clinical database is heavily used for medical research in many settings. This paper discusses design features for medical databases that facilitate their use for research. The database management system should allow complex data structures, have a syntax-facilitating collection of longitudinal data, interface with major statistical software packages, allow an extensive data dictionary, conveniently merge files, facilitate archival documentation, have an associated data entry system that allows complex logical checking, and have coordinated mainframe and microcomputer software.

HYLAS: program for generating H curves (abstract three-dimensional representations of long DNA sequences).

The computer program HYLAS generates from a standard DNA letter sequence a three-dimensional space curve (H curve) which embodies the entire information content of the original nucleotide sequence. The program can display H curves either as two-dimensional (front and side view) projections or as stereo-pair images. The curves can be marked at specific nucleotide locations, annotated, rotated for observation from any viewing angle, and manipulated for convenient side-by-side comparisons. Unlike the cumbersome letter sequences, H curves can be drastically condensed in size without losing their ability to reflect the global nucleotide-distribution pattern of the entire DNA sequence. Often, biologically important loci can be visually identified on the H curves. HYLAS is written in FORTRAN with separate mainframe (IBM-VM/CMS) and microcomputer (MS-DOS) versions. It uses the Tektronix-TCS library of graphic subroutines.

Selecting a labor information system. What to ask, what to avoid.

Payroll expenses may account for over half of all of a hospital's expenses. Manual time card processing requires an abundance of staff time and can often result in costly errors. To alleviate this problem, many healthcare facilities are implementing computerized labor information systems. To minimize the risk of selecting the wrong system, hospital administrators should ask the following questions before committing to any computerized labor information system: Is the software designed for hospital use and easily adaptable to each hospital's unique policies? How flexible is the software's reporting system? Does it include automatic scheduling that creates generic schedules? Does the system have the capability of securing time and attendance records and documenting the audit trail? Does the system include an accurate and reliable badge reader? What type of hardware is best for the particular hospital--microcomputer, minicomputer, or mainframe? Finally, to guarantee successful software installation, the vendor should have extensive experience and documentation in the system's implementation.

Financial modelling on microcomputers.

The financial modelling packages for microcomputers can be considered as falling into one of three categories:- visual spread sheets, micro base structured models and structured models which are compatible across, and allow communications between, micros and mainframes. This paper describes the three types of package, discusses the pros and cons of each, and offers a guide to system selection.

Development and deployment of a web-based physician order entry system.

The computer-based Physician Order Entry System (POES) has been employed in many clinical institutes in Taiwan. Most of the POES systems are developed in the two-tier client-server architecture, and a large portion of the systems are constructed on a mainframe or even a single PC. The exponential growth of the Internet has had a tremendous impact on our society in recent years. In consideration of the future user interface and system architecture, we have developed a three-tier web-based Physician Order Entry System and successfully deployed it in the Wang-Fang Hospital in Taipei. The system is the first POES based on three-tier and World Wide Web (WWW) in Taiwan. The system provides the Subjective, Objective, Assessment, and Plan (SOAP) structure for the physician to enter subject, object, diagnoses, medicine dosage, treatment and laboratory test request, and prints out the prescription and necessary document. The doctor can also retrieve the patient's medical record on the system. One of the special characteristics of the system is its personalized design. The doctor can define their own diagnosis, medicine and treatment database and any combination of these to facilitate their clinical work. The system has been reviewed since February 1999. The result shows that the clinical procedure has become more efficient, and the chances of omission have been reduced. The system is very stable and the Open Database Connectivity (ODBC) database access did not show any delay in the network. Since we have incorporated many new web-programming techniques, the progress of the techniques will improve the system performance in the future.

[Signal detection by analog/digital conversion using personal computers. III: Examples from general practice and organizational aspects].

Technical and organisational aspects of the setup of an analog/digital conversion are discussed in the light of two clinical reference installations. The first example deals with a closed loop regulation system used to control a cardio-surgical intervention. This setup works with repeated turns of acquisition and evaluation. The second example describes a comprehensive haemodynamic beat-by-beat analysis, involving data acquisition from FM-coded tape, preprocessing on the PC, file transfer to a mainframe and a detailed statistical and graphical evaluation within the package SAS. Special attention is given to certain technical issues and to criteria of performance. Finally, setup procedures are suggested which may help in the avoidance of certain insufficiencies which are likely to occur in a first attempt to establish A/D conversion within clinical research projects.

A microcomputer-based relational database for an academic department of human genetics.

Recent advances in microcomputer technology have made it possible for academic departments to establish their own discrete databases. This is in keeping with the modern tendency towards distributed processing on smaller systems as opposed to depending on large shared remote centralized mainframes. A database that had been implemented on a mainframe for the Department of Human Genetics of the University of Cape Town has been successfully transferred to a microcomputer system, resulting in a redesigned relational system with several significant advantages. These include faster data capture, enhanced consistency, greater computer awareness, improved economy and increased confidentiality.

Evaluating cost center productivity.

The monthly and yearly productivity summaries were developed and applied to a computer spreadsheet to aid the nurse manager in better understanding and communicating budget issues for diverse ambulatory care departments. A computerized spreadsheet using a commercially available personal computer program, such as Lotus, Quattro Pro, or Excel, can be used to more quickly and accurately track and summarize monthly budget reports. The data can be entered into the spreadsheet either manually or imported by query from the financial mainframe system. Contact your agency's finance or information department for information on how to accomplish this. Periodically acuity and resources should be measured and compared with quality monitors to maintain standards. For the past 10 years, our facility has successfully used this tool to make more informed decisions by identifying trouble spots early, and taking corrective action to avoid crisis management.

Implementation of the totally integrated hospital information system (Humane) in Osaka University Hospital.

On September 1, 1993, in the new Osaka University Hospital, we implemented a new hospital information system named "HUMANE" (Human oriented Universal Medical Assessment system by Network Environment). We had planned to organize a more effective and efficient medical care system in the new hospital and improve the medical services to patients. To succeed in constructing a totally integrated hospital information system, the original data must be entered. Most of it would be entered by doctors who are not accustomed to the operation of a computer system, thus the production of a good man-machine interface is indispensable. For this reason, we adopted a micro-medium-main frame link system for the system configuration. The interface program and the copy of the master data about each subsystem are located on the microframe. Although, all patient data is stored on the mainframe, most of the active patients' data is delivered to the mediumframe before the data is requested. This system design makes it possible to shorten the response time and to use a comfortable user interface. On the basis of this system configuration, we made subsystems that support hospital management, for example, an ordering system, a reporting system, a reservation system, a supporting system for hospitalization, a nurse supporting system, and so on. These systems promote automation control in each central service division; pharmacy, radiology, laboratory for clinical investigation and accounting section, resulting in man-power being saved. At the same time, medical service to patients is improved, because waiting time is shortened and redundant examinations or prescription are avoided.
