Development of a model of information security requirements for enterprise-wide medical information systems.

Information security methods developed within the narrow frameworks of operating system design, specific database models, and military security methods all concentrate on representation of the objects of access control, rather than on the information needs of the subjects. This approach does not adequately support the needs of the varied users of medical information systems, who must have access to information in support of multiple organizational roles. A new conceptual approach to access control in medical settings based on user requirements is discussed.

The rabies information system--a model for a common information system in human and veterinary medicine.

An information system is described in the field of rabies, which realizes the integration of information streams from human medicine as well as from veterinary medicine by help of computers. This rabies information system is based on a homogeneous and coordinated system of surveillance in connection with prophylaxis and control of rabies. It includes a modification of the case record, suggested by the WHO-Expert-Committee on Rabies. The aims of this rabies information system are: to make obvious the epizootiological situation with formation and change of foci, to show the epidemiological importance of special animals and to recognize the epidemiological situation. All this has to be fulfilled in an integrated system. Furthermore optimal treatment is guaranteed by express diagnostics and earliest possible special treatment of high-risk groups by the co-operation of human and veterinary medicine. The rabies information system was generally introduced in the GDR in 1970. It has proved to be practicable and effective especially by standardization of diagnostics, recording exposure of the patient, his treatment and partly automated evaluations of situation records and documentation of efficiency.

Making the transition from information systems of the 1970s to medical information systems of the 1990s: the role of the physician's workstation.

Many hospitals today have implemented widely disparate information systems on mainframe and mini-computer hardware. The advent of network technology in hospitals has made it possible to access information in these systems. Unfortunately, the user interfaces to applications on these systems are unique and difficult to learn, which makes them unsuitable for use by clinical services. In this paper we describe the development of a Physician's Workstation which integrates information from multiple existing information systems and discuss how the workstation makes it possible to move from the departmental systems of the present to the computer-based medical record system of the future.

Why spend the money? Justification of laboratory information systems.

Laboratory information systems (LISs) represent a major budget expense. Justification of their acquisition can be conducted through several methods. Work flow, work load, LIS experience, organization, and markets vary among laboratories; thus, each laboratory faces different challenges in determining if LIS acquisition can be justified on a sound business basis.

Network system: the integrated picture archiving and communication system with the hospital information system.

We describe the outline of Hokkaido University picture archiving and communication system (HU-PACS) and its network functions. HU-PACS processes 0.5 Gbytes of images daily through 10 acquisition devices. Functional integration of hospital information system (HIS) and PACS has been implemented. The HU-PACS can access common data base with HIS. Multi-image data-base systems provide fast throughput of image retrieval. The system is composed of 4 modules: (1) 2 image data-base systems (IDS), (2) 1 image management system (IMS), (3) image display terminals (IDT), and (4) 8 image acquisition nodes interfaced to 10 modalities and 1 film scanner. These 4 modules are connected by branch and loop type local area networks (LAN). HU-PACS has functions other than basic PACS functions. Images in optical disk library (ODL) are loaded onto magnetic disks (MD) in advance according to patient booking information, the images expected to be viewed are transferred to the local storage automatically, and the desired images can be pre-downloaded into local storage by instruction through HIS terminals.

Integration of a stand-alone expert system with a hospital information system.

A stand-alone PC expert system for evaluating the appropriateness of inpatient admissions has been integrated with an existing hospital information system. The expert system supports preadmission screening for appropriateness of inpatient admissions. The HIS provides extensive clinical data in a coded electronic form, permitting high-level decision support. The integrated system was developed for a 20 week randomized clinical trial to evaluate the effects of preadmission screening on inappropriate inpatient admissions. Three factors of the integration are considered: programmatic integration of the expert system, seamless presentation of mixed platform applications, and integration of coded data from the stand-alone application into the HIS data structure.

[Automated microbiological information system].

The microbiological information system ISM gives the possibility to collect data of patients and findings on punch strips, to transmit the findings to the senders and to store and evaluate the data according to medical points of view and for the purpose of performance statistics. The essential elements of the system are demonstrated and the basic principles of the data processing apparatus type R300 are described. Here the author particularly enters the calculator-internal testing processes for elimination of codation and punching errors. Finally the further development of the information system provided is briefly sketched. The advantages of the use of electronic data processing result from 1. the simplificstion and unification of the information relations, 2. the reduction of writing work, 3. the centralised transmission of findings, 4. the increased security of data and 5. the possibility of mathematico-statistical evaluations of the stored data material. According to its basic conception the information system ISM may be used universally and it is possible to enlarge it.

An environmental and energy information system.

The Environmental Information System Office (EISO) at Oak Ridge National Laboratory (ORNL) provides information support for researchers and administrators involved with energy and environmental policy and progress. Multiple EISO activities for various governmental agencies have resulted in establishment of compatible data bases concerned with energy environmental information, methods for effectively developing these, development and computer display of numerical daya summaries, and reports evaluating published information. Direction is provided by continuing dialogue between users and information system staff.

A computerized cancer information system.

Cancer information was made available via a computer to patients visiting the University of Connecticut Dental Clinics. The computer program was menu driven. An option allowed users to leave messages for the system owners. The computer program generated a log of usage, user comments and items chosen. The user could choose from the following topics: (1) general information on cancer; (2) diet, nutrition and cancer; (3) smoking; (4) the environment, occupations and cancer; and (5) physical checkups. An option to leave a message for the system operators was the option chosen least. Analysis of the usage log shows that the system was used substantially while people were waiting in the clinic and that at least three or four individuals used the system every clinic day. Such information systems can provide important information to the public. The novelty of the system and the lack of supervision did not deter public use.

NCTR computer systems designed for toxicologic experimentation. IV. Experiment information system.

The Experiment Information System (EIS) is a computerized data collection, maintenance, and reporting system for specified information values collected during the lifespan of animals assigned to toxicologic investigations at NCTR. The system records and/or controls experimental variables, which might ultimately affect the results, through the operation and integration of the Diet Preparation Subsystem (DPS), the Environmental Monitoring Subsystem (EMS), the Microbiology Subsystem (MBS), and the Chemistry Data Subsystem (CDS). The fifth component of the EIS, the Experimental Data Collection Subsystem (EDCS), is responsible for handling all data generated by, or attributed to, the animals from assignment until death or removal. Through integration of these five subsystems, the history of an animal while on study is recorded and stored for later recall. In addition, "routine" and "special" reports are made available through the system software which enables stringent control of the experiment by the Principal Investigator, Animal Husbandry, and NCTR Management.

NCTR computer systems designed for toxicologic experimentation. III. Breeding information system.

The Breeding Information System (BIS) facilitates management control of the breeding colony operation at the National Center for Toxicological Research (NCTR). Although this automated data handling system was initially intended to support Animal Husbandry the system's basic design, flexibility or reporting, data manipulation capabilities, and integration with other NCTR data collection systems provides BIS with capabilities that have application to other groups including the Plans and Programs and most scientific areas. This description of the System is in terms of its potential value to these diverse user groups.
