MEDLINE and PsycLIT on CD-ROM:

A survey of users of PsycLIT and MEDLINE on CDROM was performed at an academic medical library. The questionnaire was designed to gather information about the user population, satisfaction of the users, the assistance needed to use the systems, and the type of searches being performed. The majority of users were graduate students in the schools of medicine, nursing, and pharmacy. In general, users were satisfied with the performance of the systems. Assistance from a librarian, printed documentation, or another patron was required by 85% of users, and they were generally satisfied with this assistance. Most searches were performed to obtain information on a subject. The results were remarkably similar for both databases.     

CD-ROM MEDLINE Training

Most medical school libraries are attempting to provide some form of training for the CD-ROM MEDLINE user, according to this survey conducted in 1989. User guides and vendor produced tutorials are helpful but are not usually a major aspect of the training. The training sessions vary considerably in length as well as number of attendees, with individualized training being the most widespread. Few facilities offer advanced classes. A core list of training topics has been identified. Evaluation of the training has been done in only a small percentage of the libraries.     

Teaching end users the CD Plus MEDLINE menu mode in thirty minutes

Guidance through the CD Plus menu mode is warranted and has proved worthwhile. The Stowe Library's Information Services Department offers instruction once per week; the session usually lasts thirty minutes but may run longer if the attendees are particularly astute or enthusiastic. Individuals or classes may also request instruction at times that are better suited to their schedules. Librarians who search CD Plus on a daily basis will undoubtedly become facile with the direct searching mode. New end users will probably enjoy more success by using the menu mode. The menu mode does not provide documentation; therefore, a modified text of this article including the illustrations might be considered an adequate print manual for the menus. However, many of the system capabilities cannot be used unless they are taught by an experienced operator. Such a basic but necessary introduction requires approximately one-half hour. The pace will be brisk, and time for extraneous experimentation is unlikely. A successful instruction session is a result of preparation rather than improvisation. If the specific interests of the clientele in attendance are known in advance, a reworking of the examples would be appropriate. Although no formal evaluation of this instruction technique has been made, most attendees express an appreciation and understanding of the system's capabilities by the end of the session. Tangible feedback comes from seeing an end user who had participated in instruction return to the workstation on an ongoing basis to search the database successfully.

Evaluating CD-ROM versions of the MEDLINE database: a checklist

The emergence of CD-ROM (compact disc/read-only memory) versions of the MEDLINE database requires experienced MEDLINE searchers to examine assumptions about searching MEDLINE, since some expectations may not be fulfilled by this new technology. When applied to a particular CD-ROM MEDLINE product, the evaluation procedure involves testing assumptions concerning database contents; mechanics of searching; display, print, and download capabilities; and user-friendly features. The extent to which a CD-ROM product preserves and exploits important MEDLINE strengths should be assessed, e.g., the MeSH controlled vocabulary, the designation of major and minor MeSH emphasis, and the use of subheadings. Search software characteristics that affect ease of searching and quality of results also need to be examined, e.g., the ability to truncate search terms and the order of precedence in which Boolean operators are evaluated. A checklist to assist in the evaluation process is presented, including search examples for use in testing search functions.     

An evaluation of CD-ROM MEDLINE use in Thailand

An analysis of requests for CD-ROM MEDLINE* searches from June to December 1987 at the Medical Library, Chulalongkorn University, was performed. Requests were received from eighty-two places, in Bangkok and the provinces; 97.8% were from government organizations. MEDLINE on CD-ROM was available from 1982 to date. Most users requested searches covering the previous five or six years. Users were surveyed regarding the service: just over 87% found the service user-friendly. In addition, users suggested that the library conduct search training programs, and more than half of the users noted that a single work station could not meet the search load.     

CD-ROM MEDLINE use and users: information transfer in the clinical setting

Effective delivery of biomedical information to health professionals depends on the availability of systems that are compatible with the information-seeking patterns of health professionals. MEDLINE is a major source of biomedical information, but has been available primarily through libraries via telecommunications networks. The recent availability of MEDLINE on CD-ROM has made it possible to provide MEDLINE directly to clinicians without the associated problems of telecommunications and online use charges. The MEDLINE on CD-ROM Evaluation Forum sponsored by the National Library of Medicine reported on clinicians' use of CD-ROM MEDLINE at seven different clinical settings. This article summarizes the findings from these sites and places them in the context of current understanding of information-seeking behaviors of health professionals. Key issues in the design and development of information technologies in the clinical setting are also articulated.

The effect of CD-ROM MEDLINE on online end-user and mediated searching: a follow-up study

Indiana University School of Medicine Library (IUSML) has traditionally been a high volume searching institution. The dramatic effect of CD-ROM on online end-user searching and the negligible effect on mediated searching was reported in an earlier study. This follow-up study reveals that the proportion of mediated searching has been drastically reduced from 94% in 1986/87 to 39% as of November 1989. Mediated searches are declining in absolute numbers as well. End-user searching, by contrast, has increased by 54% percent over the previous year. A related trend is the increased use of CD-ROM by the librarian as an alternative to mediated online searching. These trends are expected to continue as IUSML expands its CD-ROM operation to include other databases. As mediated searching declines, the librarian's role will increasingly include end-user training.     

Testing the new technology: MEDLINE on CD-ROM in an academic health sciences library.

The UCLA Biomedical Library tested a six-month portion of the MEDLINE database on compact disc to determine its potential application in a large, university health sciences library environment. Patron response to the system, previous search experience, and actual search strategies were recorded. Although the overwhelming user response was positive in spite of little previous experience with online searching, results show underutilization of the system because of both software and hardware problems. The implications of this test underline the important role libraries must take in guaranteeing that new reference tools like CD-ROM be made genuinely user-friendly.     

The effect of CD-ROM MEDLINE on online end user and mediated searching.

Since 1970, Indiana University School of Medicine Library (IUSML) has traditionally been a high volume online searching institution. The library recently implemented an end user searching program which includes MEDLINE on CD-ROM. The effect of CD-ROM on online end user and mediated searching is discussed. Comparative statistics are provided by category of search service. CD-ROM has had a dramatic lowering effect on online end user searching and has had little effect on mediated searching. IUSML's experience with CD-ROM technology has been a positive one. Trained end users have become IUSML's greatest asset.     

A study comparing centralized CD-ROM and decentralized intranet access to MEDLINE

OBJECTIVE: The purpose of this study was to evaluate the efficacy of a decentralized intranet access in each medical department as opposed to centralized unique MEDLINE access in the medical library. DESIGN: A two-phase questionnaire to evaluate MEDLINE use was given to junior and senior physicians at Rouen University Hospital (RUH). Phase I (August-October 1996) corresponded to a time period when centralized access was the only means of access available and phase II (August-October 1997) to a time period following the introduction of decentralized intranet access. RESULTS: A total of 168 physicians filled out at least one phase of the questionnaire, among whom 123 (73%) filled out both phases. Use of MEDLINE significantly increased in 1997 (average of 10.2+/-1.1 searches in three months) versus 1996 (average of 4.9+/-0.7 searches in three months, P<0.0001). The aim of searches changed, becoming significantly more care oriented in phase II (P<0.0001). The number of searches performed by the physicians alone increased (P<0.0001) and searches performed by the librarian decreased (P<0.0001) in phase II. The method of searches also changed, as searches by author (P< 0.0001), by journal (P = 0.0042), and by free word (P = 0.0027) increased in phase II. Knowledge of the following concepts of MEDLINE significantly increased: explosion (P<0.0001), scope note (P<0.0001), Abridged Index Medicus (AIM) journals (P<0.0001), Medical Subject Headings (MeSH) qualifier (P<0.0001), and focus (P<0.0001). CONCLUSION: A decentralized intranet access to MEDLINE increased the number of searches and knowledge of this bibliographic database. MEDLINE intranet access modified the purpose and the methods of searching.
