Impact of end-user search training on pharmacy students: a four-year follow-up study.

The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program.

An evaluation method of computer usability based on human-to-computer information transmission model.

This paper proposes a new evaluation and prediction method for computer usability. This method is based on our two previously proposed information transmission measures created from a human-to-computer information transmission model. The model has three information transmission levels: the device, software, and task content levels. Two measures, called the device independent information measure (DI) and the computer independent information measure (CI), defined on the software and task content levels respectively, are given as the amount of information transmitted. Two information transmission rates are defined as DI/T and CI/T, where T is the task completion time: the device independent information transmission rate (RDI), and the computer independent information transmission rate (RCI). The method utilizes the RDI and RCI rates to evaluate relatively the usability of software and device operations on different computer systems. Experiments using three different systems, in this case a graphical information input task, confirm that the method offers an efficient way of determining computer usability.

Telework as an employment option for people with disabilities.

This feasibility study, based on intensive casework, examined the potential of home-based teleworking arrangements for people with severe physical disabilities. Eleven teleworking arrangements, each involving a unique combination of work, working conditions and worker characteristics, were set up in different parts of Ireland and monitored over periods ranging from 6 to 18 months. Eight were still operational at the end of the project and, with one exception, were set to continue as longer-term arrangements. Outcomes from this action-research project suggest that teleworking is a feasible form of employment for such persons--provided care is taken over selection of workers, identification of work that is suited to the telework format and management of telework units by employers. They also suggest that teleworking arrangements can be quite flexible, ranging from examples in which work is performed mainly from home to those which combine home-based activity with varying degrees of conventional office-based activity. It is concluded that telework will create new opportunities for people with severe disabilities, as well as enabling others who become disabled during employment to retain their jobs. However, it is important that workers are appropriately trained in the use of computers and advanced telecommunications and, in many cases, home-delivered training is required.

[Changes in the rate and accuracy of information processing in the computer training of middle-grade pupils].

The computer enters more and more quickly the new school. Therefore an important problem is the influence of computer training on the velocity and accuracy of information processing. For this purpose were examined 28 school-children from VI-VII class, participating in computer training, computer plays and traditional lesion. This activity was carried out in the computer study of the Pioneer Palace, Sofia. An electronic determinator with test programme, containing preliminary arranged succession of 50 visual stimulants on red, blue, green, yellow and white colours, at vas used at 1,2 s. speed. The changes in the correct, delayed and wrong reactions were traced. The results as a whole point out, that the computer training, on the one hand, has no unfavourable effect on the velocity and accuracy of information processing, and on the other hand--forms positive psychoemotional adjustment to work.

A software system for interactive and quantitative visualization of multidimensional biomedical images.

A comprehensive software system called ANALYZE has been developed which permits detailed investigation and evaluation of 3-D biomedical images. The software can be used with any 2-D or 3-D imaging modality, including x-ray computed tomography, radionuclide emission tomography, ultrasound tomography, magnetic resonance imaging and both light and electron microscopy. The package is unique in its synergistic integration of fully interactive modules for direct display, manipulation and measurement of multidimensional image data. Several original algorithms are included which improve image display efficiency and quality. One of the most versatile and powerful algorithms is interactive volume rendering, which is optimized to be fast without compromising image quality. An important advantage of this technique is to display 3-D images directly from the original data and to provide on-the-fly combinations of selected image transformations and/or volume set operations (union, intersection, difference, etc.). The inclusion of a variety of interactive editing and quantitative mensuration tools significantly extends the usefulness of the software. Any curvilinear path or region-of-interest can be manually specified and/or automatically segmented for numerical determination and statistical analyses of distances, areas, volumes, shapes, densities and textures. ANALYZE is written entirely in "C" and runs on several standard UNIX workstations. It is being used in a variety of applications by over 40 institutions around the world, and has been licensed by Mayo to several imaging companies. The software architecture permits systematic enhancements and upgrades which has fostered development of a readily expandable package. ANALYZE comprises a powerful "visualization workshop" for rapid prototyping of specific application packages, including applications to interactive surgery simulation and radiation treatment planning. ANALYZE offers the potential to accurately and reproducibly examine, from images, the structure and function of any cell, tissue, limb, organ or organ system of the body, much like a surgeon or pathologist might do in real life, but entirely non-invasively, without pain or destruction of tissue. These capabilities promise exciting new insights into the basic processes of life, and major advances in health care delivery through improved diagnosis and treatment of disease.

[Changes in the rate and accuracy of information processing in the computer training of upper-grade pupils].

The basic activity of the student during the "computer training process" is the introduction and processing of information. In the dialogue regime of work, between student and computer, the velocity and accuracy of the information processing take important place. In this aspect, special attention is given to the changes in the indicated indices during the computer lesson, computer plays and the traditional training. Studies are carried out on 30 students from classes X and XI, educated in vocational school "V. Levski", the town of Pravets. For the purpose is used electron determinator with test programme, containing consecutively exposure to 50 visual stimulators in red, blue, green, yellow and white colours at 1,2 s/speed. The results as a whole show that the most favourable results concerning the computer plays, very likely could be explained with the diversion effect and the positive motivation adjustment to the activity performed. By means of dispersion analysis is established, that only the type of activity has an essential effect on the velocity and accuracy of the information processing.

[Computers and education needs].

The purpose of this study was to identify nurses' computer training needs. A 20-statement questionnaire was circulated to 30 nurses. From the 26 responses received, a profile was created of the target group (nurses working in a teaching hospital), with a view to determining their current and desired level of knowledge. A number of diverse training needs were revealed through the study. The most interesting aspects, from the nurses' point of view, were those related to clinical practice and education. Figure one illustrates the low level of current knowledge of computer science. Figure two, however, demonstrates the high level of interest on the part of respondents (desired level) in becoming more computer literate and their wish to use computers in a wide range of applications, including teaching, health care delivery, clinical decision making and in-service training. Figure three highlights the training needs identified under each statement. The establishment of an information system in a teaching hospital setting is not dealt with in this article. This will be the subject of a second article, to appear next month. A number of teaching variables are described here, including the instructor, the learner, the training process itself, content, media and budgetary constraints. The outline of a training program will be proposed in a third and final article.

A study to enhance clinical end-user MEDLINE search skills: design and baseline findings.

OBJECTIVE: To determine if a preceptor and timely, individualized feedback improves the performance of physicians in searching MEDLINE using GRATEFUL MED in clinical settings. DESIGN: Randomized controlled trial. SETTING: A 300 bed primary to tertiary care teaching hospital. Computers were installed in wards and clinics of 6 major clinical services, and the emergency room, intensive care and neonatal intensive care units. SUBJECTS: All physicians and physicians-in-training from the departments of Medicine, Family Medicine, Surgery, Psychiatry, Pediatrics, and Obstetrics and Gynecology were included if they made patient care decisions for at least 8 weeks during the study period. INTERVENTION: All participants were given a 1-hour training class and 1 hour of individualized searching with 1 of the 2 study librarians. After training, participants were randomized to a control group who received no further intervention or to an intervention group in which each person chose a clinical preceptor experienced in MEDLINE searching and received individualized feedback by a study librarian on their first 10 searches, indicating search quality and providing suggestions for improvement. Feedback was mailed the first week day after the search was done. MAIN MEASURES: Baseline characteristics by study group, department and level of training, study participation rates, and searching rates. MAIN RESULTS: 308 of 392 eligible physicians joined the study. Participation was almost 80% with some variation by department and level of training. Excellent balance in the baseline characteristics was achieved for the 2 groups, as well as for the number who did first searches. Intervention group participants searched MEDLINE more often than did controls (3.5 searches per month vs 2.5 per month for controls, P = 0.046). The recall and precision for first searches for both groups was significantly less than that of librarians. The analysis of study data will be completed by September 1991. CONCLUSIONS: Clinicians are willing to do self-service searching of MEDLINE in clinical settings but their precision and recall are less than a trained librarian at baseline. Search skills enhancements are needed and the effect of feedback and preceptors is being tested. SOURCE OF FUNDING: U.S. National Library of Medicine and Ontario Ministry of Health.

Cognitive representations, control, and understanding of complex systems: a field study focusing on components of users' mental models and expert/novice differences.

Users' mental models of systems are frequently asserted to be important in their interactions with those systems. Although there are few explicit definitions of mental models in the literature, mental models are assumed to be important and researchers have seemed to accept and understand the concept intuitively. In our research, we have extracted three themes from the definitions of mental models including: (1) the relations among features or components of a system; (2) the capability of the mental model to aid in the control of the system; and (3) the capability of the mental model to enhance the user's understanding of the system. The relationships among the components of users' mental models, including procedural and declarative knowledge, perceptions of the use of system features, and the relations among the similarity of use of system features, were investigated in a field study. Trained and untrained novice users of a new business phone system rated the similarity of use of nine standard features on the phone. These ratings were used to derive cognitive representations of the relations among the system features. Users' ratings of features on univariate scales about the use of the features and scores obtained on a test of procedural knowledge were related to these representations. The two novice groups' mental models were similar except for the perception of one feature; it was more accurately depicted in the trained users' representation than those who did not attend a training programme. Two types of experts' similarity of use ratings were evaluated to determine an 'appropriate' representation of the use of the system features; this was then compared to the novices'. This comparison suggested that there were deficiencies in the mental models of novices. Designing training programmes and instructional aids for systems using the discrepancies between novices' and experts' mental models are discussed.

End-user participation in the needs assessment for a clinical information system.

The successful introduction of a new information system requires technological and behavioral changes. Intended users of the new system should participate in defining goals for the system, examining alternatives for achieving these goals, and selecting from these alternatives. Broad-based end-user involvement is especially useful during the needs assessment (goal definition) phase, both to identify the diverse expectations of the end-user community and to develop a sense of system ownership by these users. System planners can stimulate active end-user involvement by inviting each constituent user group (for example, each hospital department) to assume responsibility for specifying its objectives for the new system. The collection of all groups' objectives defines the organization's expectations of a new system, provides a means for comparing systems, and aids in predicting the overall acceptance of any proposed system. Each constituent group's list of objectives likewise provides a measure of anticipated acceptance for that group.
