Full-text and bibliographic database searching in the health sciences: an exploratory study comparing CCML and MEDLINE.

An exploratory study to investigate perceived differences between searching full-text databases and bibliographic databases was undertaken. BRS's full-text database, Comprehensive Core Medical Library (CCML), and BRS's current MEDLINE file (MESH) were compared. Identical literature search topics were run in the two databases and the results evaluated regarding currency of search results, success in answering specific questions, uniqueness of information retrieved, and relevancy of retrieval. Additionally, connect time and costs were noted to aid in determining the feasibility of offering full-text database searching as a service for which the authors' institution would charge.

Accessing the literature on outcome studies in group psychotherapy: the sensitivity and precision of Medline and PsycINFO bibliographic database searching.

BACKGROUND: Bibliographic databases such as Medline and PsycINFO are major sources of initial information for systematic reviews. This study investigates the adequacy of Medline and PsycINFO in retrieving articles describing outcome studies of group-based psychological treatments. METHOD: Ten journals publishing a high number of group psychotherapy articles were hand searched for the publication years 1993 and 1994. They were then searched using narrow and broad strategies developed for each database. RESULTS: The sensitivities (number of relevant articles identified by each search divided by the total number of known relevant articles identified by all searches) of narrow and broad Medline searches were 28% and 67% respectively. Precision (the number of relevant articles identified by a search divided by the number of both relevant and irrelevant articles identified by the search) was 91% and 35% for narrow and broad searches respectively. The sensitivities of narrow and broad PsycINFO searches were 8% and 47% respectively. Precision was 30% for the narrow search and 36% for the broad search. The hand search identified 94% of all known articles. CONCLUSIONS: PsycINFO performed more poorly than Medline. Although it was possible to identify 67% of outcome studies using Medline, the low precision of the necessary search strategies would make it uneconomical in practice. Abstracts of papers not identified by either search strategy were examined for possible reasons for this failure. For Medline this was generally due to the terms used to identify group psychotherapy. For PsycINFO it appears that the indexing system does not allow the easy identification of outcome studies.

Evaluation of drug interaction document citation in nine on-line bibliographic databases.

OBJECTIVE: To compare nine on-line bibliographic databases to obtain bibliographic references on specific drug interactions. DESIGN: Seven bibliographic databases were selected for their ability to provide information concerning drug interactions: EMBASE, MEDLINE, TOXLINE, BIOSIS, Chemical Abstracts (CAS), PHARMLINE, and International Pharmaceutical Abstracts (IPA). Two French on-line bibliographic databases (i.e., PASCAL, BIBLIOGRAPHIF) were also tested to compare them with the other international databases. Twenty drug interactions were selected randomly using the journal Reactions Weekly 1993. MAIN OUTCOMES MEASURES: The total number of references, the number of potentially relevant references, the number of case report references, the number of unique references in the total number of references, and the number of unique references between potentially relevant references were analyzed by using the Friedman two-way ANOVA by ranks. For each database, relevance and relative recall were calculated. RESULTS: For the total number of references, EMBASE was significantly more comprehensive then all other databases (p < 0.05). EMBASE had a significantly greater number of potentially relevant references than IPA, PHARMLINE, CAS, and BIBLIOGRAPHIF (p < 0.05). For the total number of case report references, only one significant difference, between EMBASE and BIBLIOGRAPHIF (p < 0.05), was observed. MEDLINE and TOXLINE had the lowest cost per potentially relevant reference. CONCLUSIONS: To obtain bibliographic references on drug interactions, the first step should be to search MEDLINE or TOXLINE; the second step, for completeness, should be to search EMBASE.

Searching for information on toxicological data of chemical substances in selected bibliographic databases--selection of essential databases for toxicological researches.

By using information from printed and online database guides, 18 online bibliographic databases (BD), which cover literature on toxicology were selected from 5 hosts. A search for literature containing information on three selected chemicals was carried out with each of the databases, and the number of documents relevant to toxicology found in them was compared by computer-assisted analysis. Some databases yielded very little information pertinent to toxicology, while others provided a considerable amount. In addition, the databases contained numerous duplicates (references common to more than one database). Most of the relevant documents could be obtained using only 8 of the 18 BDs selected. These databases are: Biosis Previews (BIOSIS), Chemical Abstracts (CA), Chemical Safety Newsbase (CSNB), Excerpta Medica (EMBASE), National Institute for Occupational Safety and Health (NIOSH), Scisearch, Toxicology Information Online (TOXLINE) and the former Toxicology Literature (TOXLIT).

Testing the Database of International Rehabilitation Research: using rehabilitation researchers to determine the usability of a bibliographic database.

OBJECTIVES: This study tested the usability of the Database of International Rehabilitation Research, a bibliographic database developed by the Center for International Rehabilitation Research Information and Exchange (CIRRIE). METHODS: Potential users, i.e., rehabilitation researchers, were asked to participate in a usability study. Test questions were designed to represent common tasks performed in a bibliographic database. Participants were asked to think aloud during the test so that both their actions and comments could be recorded. RESULTS: This study identified common problems that participants had while searching the database and aspects of the database that needed improvement. CONCLUSIONS: Usability testing proved to be an effective method for evaluating database effectiveness and user satisfaction. The method used provided valuable information about how the database searchers approached their searches as well as how they performed them.

Searching bibliographic databases effectively.

The ability to search bibliographic databases effectively is now an essential skill for anyone undertaking research in health. This article discusses the way in which databases are constructed and some of the important steps in planning and carrying out a search. Consideration is given to some of the advantages and limitations of searching using both thesaurus and natural language (textword) terms. A selected list of databases in health and medicine is included.

Creating local bibliographic databases: new tools for evidence-based health care.

The Internet has created new opportunities for librarians to present literature search results to clinicians. In order to take full advantage of these opportunities, libraries need to create locally maintained bibliographic databases. A simple method of creating a local bibliographic database and publishing it on the Web is described. The method uses off-the-shelf software and requires minimal programming. A hedge search strategy for outcome studies of clinical process interventions is created, and Ovid is used to search MEDLINE. The search results are saved and imported into EndNote libraries. The citations are modified, exported to a Microsoft Access database, and published on the Web. Clinicians can use a Web browser to search the database. The bibliographic database contains 13,803 MEDLINE citations of outcome studies. Most searches take between four and ten seconds and retrieve between ten and 100 citations. The entire cost of the software is under $900. Locally maintained bibliographic databases can be created easily and inexpensively. They significantly extend the evidence-based health care services that libraries can offer to clinicians.

Review of Papyrus bibliographic database software.

Papyrus is an inexpensive bibliographic database which provides some features not found in other similar packages. Its flexibility in handling references of many types and formats, its capacity for integration with manuscripts prepared with word processors, its capacity for importing references from national databases and its ability to perform microcosmic literature searches are attractive features. Because Papyrus has tackled a complex task, mastery of the intricacies of the program may present a substantial challenge to novice computer users. Although the manipulation of an existing customized bibliographic database would seem to be attractive for any researcher or author who prepares manuscripts for publication, the optimal use of the program also requires an extensive commitment of time and labor for the initial entry of all pertinent references into the database. While this could be accomplished gradually in conjunction with the preparation of individual manuscripts, the creation of a complete file of references could require hundreds of hours of labor. Individual authors, as well as larger research groups, should be prepared for this type of commitment before acquiring the Papyrus system.

Comparison and evaluation of nine bibliographic databases concerning adverse drug reactions.

Few evaluations and statistical comparisons of bibliographic databases have been published. As a drug information center, we were particularly interested in databases providing references on adverse drug reactions (ADRs). Ten drugs were randomly chosen from the 2000 files at our center. Nine databases were selected according to the high frequency of references concerning ADRs: eight online systems (MEDLINE, BIOSIS, TOXLINE, Iowa Drug Information System, PASCAL, EMBASE, PHARMLINE, and International Pharmaceutical Abstracts [IPA]), and one Compact Disk Read Only Memory (CD-ROM) system (Core MEDLINE). The total number of references, the number of references from 1987 to 1989, and the number of relevant references from 1987 to 1989 were analyzed using the Friedman two-way ANOVA by ranks. The overlap between databases for only one drug, carboplatin, and the quality:cost ratio were also studied. Considering the total number of references, TOXLINE and EMBASE were significantly superior to IPA, PHARMLINE, PASCAL, and Core MEDLINE. For the period 1987-1989, EMBASE was significantly superior to PASCAL, IPA, PHARMLINE, and Core MEDLINE with regard to total number of references, and significantly superior to PASCAL, Core MEDLINE, and IPA with regard to relevance. MEDLINE, TOXLINE, and EMBASE had the best quality:cost ratio. EMBASE had the slightest overlap of references, with 53 percent of the unique references on carboplatin. This comparative evaluation showed that the ability of bibliographic databases to provide information on ADRs is dependent on both the size and the quality of each database.

Searching for information on chemical substances in selected biomedical bibliographic databases.

A method was developed which allows effective searching for information on chemical substances in databases. Several searches for chemicals in bibliographic databases were carried out to analyse the method of indexing chemical names. The recall rates of documents were compared to evaluate information resources as well as searching strategies. Recall rates of documents searched with the CAS Nos. were compared to those searched with substance name. It turned out that searching for substances is most specific and fastest with CAS Nos. They should always be used whenever possible. However, this is not sufficient in many BDs, making an additional search using chemical names necessary. Specific search options that have to be considered for each database are reported.
