FarFetch--an Internet-based sequence entry server.

This communication is to announce the availability of a network server for biological sequence database entries which will allow scientists to fetch entries in a desired format directly into their file store. This server will use TCP/IP protocols allowing any user with an Internet connection to participate. FarFetch will allow users to obtain sequence entries in a directly usable form as opposed to conventional e-mail based sequence retrievers. This server also differs from Gopher and WAIS servers in that the sequence entry is written into the user's file store in a format that is immediately usable. Clients for the OpenVMS, Unix and Macintosh operating systems have been written and are available via anonymous ftp. Development of MS-DOS and Windows clients is planned. There will be no usage fees associated with the server.

Design of a computer-assisted programme supporting the selection and clinical management of patients referred for liver transplantation.

The paper describes the knowledge-base of the expert system OLT 1, developed to support medical decision-making in patients referred for liver transplantation. The paper goes through the real clinical problems, and describes both structural (organization of the domain knowledge) and functional aspects (reasoning algorithm and strategies for clinical decision). According to the programme, patients referred to Liver Transplant Centres may be enrolled and ranked in the waiting list, included in a stand-by list for treatment and re-evaluation, or discharged. All decisions are made on the basis of well-assessed and objective criteria.

Interactive video instruction increases efficiency in cognitive learning in a baccalaureate nursing education program.

An interactive videodisc instruction module on therapeutic communication in nursing was evaluated to assess its impact on learning and retention. A pre-test, post-test, re-test, control group design was used on two comparison groups. Results showed that the intervention group met therapeutic communication course objectives more efficiently than the control group. Although all 65 student study participants met therapeutic communication course objectives equally well and at a high level by the end of the semester, the intervention group had achieved these objectives at a higher level than the control group within the first month of the semester. The results support the use of computer assisted instruction, and more specifically, interactive videodisc instruction for teaching therapeutic communication skills and permitting an increase in the student-faculty ratio, with no loss in quality.

[A UNIX-based electronic data processing system for routine use in a trauma surgery department].

A computer program for a UNIX workstation has been developed to support routine activities in a surgical department. A relational database contains reports on operations, medical letters and further data imported from independent computer subsystems outside the department. Data are accessible at 15 terminals and PCs through a simple and intuitive user interface with a mouse. The patient record is organized in a hypertext fashion and permits direct access to the various types of documents in a consistent manner. The implementation is currently used to manage information on 40,000 patients and has proved valuable in daily routine over a 2-year period.

Performance characteristics of a multimedia system for clinical data management.

This study describes a multimedia, computer-based system developed to record and retrieve clinical images, associated dictated commentaries, and textual and numeric data from patients with cancer or hematologic diseases. Objective performance was analyzed by (1) success rate for data input and retrieval, (2) speed of image retrieval, and (3) quality of stored images. During a 1-year period, 587 diagnostic images were recorded with dictated or typed summaries of pertinent clinical information. Subsequent retrieval of stored data was performed three times (n = 1761) with 100% reliability. The average time for retrieval of random images was 6.4 seconds (SD = 1.7 seconds), including operator time. Image quality was scored by a four-point scale: the average score was 3.58 (SD = 0.5), and all images displayed sufficient quality to represent a wide range of diagnoses. These data demonstrate that multimedia computer technologies can enhance the organization and management of clinical images needed for medical education, clinical trials, and daily care of patients with cancer and hematologic diseases.

[PACS-2000].

Digital radiology and picture archiving and communication systems (PACS) with filmless reporting at electronic workstations are a great challenge for radiology. There are the possibilities of improving the quality of diagnosis, of working more efficiently and of achieving economic savings, but on the other hand the position of radiology within the hospital may be put at risk. The technical means for the implementation of PACS are largely available. Wide acceptance in the market depends inter alia on the availability of open systems with standardized interfaces.

[Architecture and organization of PACS workstations: a critical overview].

The development and implementation of a workstation capable of handling medical images and data from different imaging modalities require a particular user-interface design so that it is easily accessible by clinical and non-computer-oriented users. Appropriate management of medical images from different imaging modalities is the first step toward the integration of multimedia information in a coherent computerized medical record. It is also the most challenging part because the amount of data obtained in the form of images is much greater than the text, graphic or sound elements. The proportion of clinical investigations based on imaging modalities is also constantly increasing. The goal of this paper is to review some important design concepts of imaging workstations and to explore the needs and requirements of medical image display and manipulation.

[Station of interpretation].

Revisualization or image processing stations are constantly improving, but they have not yet been designed to replace the x-ray display unit for the interpretation of films. An improvement of the integration of these stations within the hospital computer system and functional enrichment must be achieved in order to prepare for the "digital" era. Although this prospect is not for the immediate future, it is important to develop tomorrow's tools with a minimum of intelligence to facilitate their acceptance.

Virtual reality: applications in medicine and psychiatry.

Virtual reality (VR) is a coined description of a new computer-based technology that allows the user to enter a 3-D artificial world. Inside this world, the user can look around, move around and interact within computer worlds. The user can fly, visit exotic lands, play with molecules, "enter" cardiac chambers and watch blood swirl or do simulated surgery. The possibilities are staggering and it is important that physicians become literate in this visual experience. In this article I will introduce the technology in the field, discuss some medical applications already in use, and speculate on some potential uses in my field of interest: psychiatry.

Does an integrated medical workstation really help clinicians?--A formal user evaluation.

A formal user evaluation of an integrated medical workstation for support of clinical data analysis is described. Twenty-six users participated in an assessment study that consisted of a self-instruction course, followed by an experiment in which six clinical data analysis problems had to be solved, and the assessment was concluded with an evaluation form. To facilitate an objective and quantitative assessment, the time spent to the course and to the problems, as well as completeness, correctness, number of solving attempts and persistence were measured. Not all problems were solved by all participants. From an analysis of the measurements, the following conclusions were drawn. (1) Clinicians correctly solved about 69% of all problems tackled. However, they skipped 33% of the problems. (2) Non-clinicians correctly solved 87% of the tackled problems and skipped only 10%. (3) The performance of users not experienced in clinical data analysis was raised to the level of those with clinical data analysis experience. (4) An inventory which can be used to direct future developments was made of the errors of interaction. This assessment study has contributed to gaining insight into the conceptual problems and practical bottlenecks clinicians have with clinical data analysis.

Developing a general practice medical workstation: the integration aspect.

ISAAC (Integrated System Architecture for Advanced Primary Care) is a project aiming at developing information technology and telematic support in the specific field of General Practice--and more broadly in the Primary Health Care sector--within the health care systems of different European Countries. The project aims at improving the work of the General Practitioners through the development of a useful and usable medical workstation for day-to-day patient care. Moreover ISAAC has the goal of prototyping an integration architecture for the improvement of the communications between the ISAAC workstation and heterogeneous application environments, namely other components of the health care system. This paper deals with a general description of the design along with a discussion of the adopted approach to fulfill the integration requirements.
