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.

Automation of the patient history--evaluation of ergonomic aspects.

In this study it was investigated in quantitative terms how patient reactions were on automated history-taking. The study is part of a comprehensive project, in which also physicians participated in the validation of such computerized medical records. In total 99 patients, visiting the outpatient clinic of Internal Medicine for the first time, took part in this in-depth study, in which they could express themselves via an interactive and modified terminal and keyboard. The questionnaire that was used in the system contains 28 different screens. Patient complaints are entered together with data on frequency, severity, onset, and duration. The patient may indicate his physical complaints on a stylized picture of the human body. Of the 99 patients, 67 answered the full questionnaire, and another 16 the main part. On the average, 66 min were needed. Younger patients do complete the history in a significantly shorter time than older patients, resulting in relatively more completed histories for the younger group. Quick patients answered on the average 3.5 questions per minute, the slow patients only 2.5. This was strongly correlated with patient familiarization, that has also been investigated: patients who had a quick familiarization were able to finish within 50 min. Patients who needed no help at all in using the system had even answering rates of 3.9/min.

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.

The effects of analogical training models and age on problem-solving in a new domain.

Young and middle-aged adults learned a microcomputer drawing package either with or without an analogical model of the package. Following training, problem-solving flexibility was assessed. Although no age differences were obtained following no-model training, middle-aged subjects performed worse than young subjects following model-based training. These results support the hypothesis that model-based training encourages elaboration and abstraction processes, and that older adults are less likely or less able to engage in such processing.

Evolution of an end-user training program.

The University of Illinois at Chicago Library of the Health Sciences has taught end-user classes on the MEDLARS system since early 1985. Registration, class composition, and, most importantly, class organization evolved continuously during the first year of operation. Several feedback mechanisms were used. An examination of the past training and specialization of participants helped to determine teaching examples and pace; a more varied group of participants necessitated a broader range of examples and increased explanations. Participant evaluation forms and oral comments helped define scheduling, agenda, and the need for additional equipment and practice time. Further evaluation will center on the searching done by the program's alumni.

Drug information skills for pharmacy students: curriculum integration.

For pharmacy students to provide optimal and complete pharmaceutical care, it is vital that they develop drug information skills. At the University of Southern California, the School of Pharmacy and the Norris Medical Library have established an interactive educational program. Library programs support an increasingly complex progression of information retrieval, evaluation, organization, application, and communication. Librarians are systematically involved in all four years of coursework for the doctor of pharmacy degree. Training and experience in computer literacy and online database searching are included in the library components. Description of the educational program covers its beginning a decade ago, current status, and future in an environment of rapidly advancing technology.

[Problems of the training of medical personnel in computer technology].

The author discusses the article by Gavrilenko A. F. et al (Soviet Public Health, 1987, N 10, p. 9-12) and tackles the problems of training medical staff in computer science and computing machinery. In is proposed to direct the curriculum at job control, fundamentals of economics, mathematics, algorithmics, programming. The proposal to pay special attention to medical automated management systems, primarily used in medico-sanitary units of industrial enterprises, is argued.

Computer use and education in radiology residency programs.

Computers play an increasingly important role in radiology education and research. We surveyed all U.S. residency programs to assess computer availability, education, and use by residents. Out of 210 questionnaires sent, 132 were returned (63% response). Areas of inquiry included computer equipment and software as well as resident use of facilities. Opinions were also solicited concerning the importance of computer literacy and education. Sixty-nine percent of the respondents have computer facilities (61% within the department). Predominant uses include scientific papers, slides/audiovisual presentations and resume preparation. Popular software includes word processing, spreadsheets, databases and graphics. Of those training programs with computers, 85% provided computer education, and most (70%) felt computer training was very important. Forty-seven percent expected their residents to have at least passing acquaintance with computers. However, in 60% of programs with computers, the computers are used by less than half the residents. Of those programs without a computer, 61% provided no computer training, and only 44% felt computer education was very important. A sizable minority of radiology residency programs are still without computer facilities. Those programs that have computers tend to place a greater emphasis on computer education and literacy for radiology residents. However, even in programs that have computers, it seems they are often underutilized by residents.

[The effect of training with computer equipment on the visual analyzer of 1st-grade pupils].

Examination are carried out on 64 school children Ist class from school "104", town of Sofia where computer training on mathematics and mother tongue is introduced in the frames of pedagogic experiment. The studies are performed parallelly at traditional and computer lessons, realized in two variants (with one and two school hours daily). In order to establish the functional status of the visual analyzer during computer training the following methods are used: studying the distance of the nearest point for clear vision (punctum proximum), stability of clear vision, threshold of the electric eye sensitivity, critical frequency of fusing of the light flickerings. A full preliminary ophthalmological examination is made by "Vision test", as well as chronometric control of each student to establish the real time of work with computers. Taken into consideration are also the data for illumination of the working places in the computer studies and class rooms where the traditional school hours are held. The analysis of the data received shows that the computer training (1 and 2 computer lessons daily) with schoolchildren, Ist class, has no unfavourable effect on the functional status of the visual analyzer in the limits of study hours up to 25 minutes.

Implementing an integrated clinical information system.

The authors examine the vital role nursing professionals have played in the successful implementation of a sophisticated computer system at a regional medical center in the midwest. From preselection analysis through training and implementation, nurses have assumed primary responsibility for managing the multifaceted adaptation and installation of a comprehensive array of patient care functions. This experience can serve as an invaluable example of the relationship between information management, patient management, cost management, and quality enhancement in the hospital setting.
