Improving access to the international coverage of reports of controlled trials in electronic databases: a search of the Australasian Medical Index

Introduction: Locating reports of trials from journals not indexed in the major databases presents difficulties to systematic reviewers, and may be a factor in improving the reliability of the reviews. Objectives: To identify and make available reports of controlled trials from the Australasian Medical Index (AMI). To measure the quality of indexing of trials in AMI. Methods: Using a highly sensitive search strategy consisting of methodology indexing and free‐text terms, records from AMI were read for reports of controlled trials. Trials meeting the criteria were submitted for inclusion in The Cochrane Controlled Trials Register (CCTR) and assessed for the quality of their indexing. Results: 3621 records were downloaded, of which 512 were identified as reports of controlled trials (317 RCTs; 195 CCTs) and submitted to CCTR. The precision of methodology indexing terms was 60%, but sensitivity just 18%. The quality of indexing of trials was generally poor with only 50 tagged with the RCT/CCT publication type term. 453 reports (88%) were not previously available in CCTR. Conclusions: The large proportion of trials found to be unique to the AMI database increases the pool of studies available to systematic reviewers, and helps ensure CCTR remains the most comprehensive source of trials.     

A comparison of journal coverage in Psychological Abstracts and the primary health sciences indexes: implications for cooperative serials acquisition and retention

An overlap study was performed to identify important psychology journals that are also of interest to biomedical scientists and health care practitioners. The journal lists of Index Medicus, Hospital Literature Index, Cumulative Index to Nursing and Allied Health Literature, and International Nursing Index were compared with the journal list of Psychological Abstracts. A total of 357 Psychological Abstracts titles were also in one or more of the health sciences indexes. A core list of forty-five titles covered by all of the indexes is presented in the Appendix. Results of the study are discussed vis-à-vis cooperative serials acquisition and retention efforts.

Bibliography of Bioethics and Index Medicus: comparison of coverage, publication delay, and ease of recall for journal articles on bioethics

Citations selected from the bibliographies of recent texts, a specialized subject bibliography, and review articles were checked in both Cumulated Index Medicus (IM) and the Bibliography of Bioethics (BB) to compare coverage, publication delay, probable causes of indexing and retrieval failure, and the ease with which relevant citations were retrieved. The study also attempted to determine whether BB included appropriate articles from the MEDLINE database in a timely and systematic manner. While 98% of the IM citations appeared within a year of publication, 79% of the BB citations appeared two to three years after their publication dates. The average citation appeared twice as frequently in IM as in BB.

Quality of abstracts in articles submitted to a scholarly journal: A mixed methods case study of the journal Research in the Schools

The present formatting and content of abstracts in educational research might be one barrier preventing wider dissemination and use of such research. Structured abstracts, with specific formatting and content requirements, might help researchers disseminate their work more effectively and efficiently. The purpose of this study was to investigate 2 years of abstracts of empirical research articles submitted to Research in the Schools and to determine the extent to which the abstracts were underdeveloped, thereby suggesting the need for structured abstracts. Of the 74 articles reviewed, 35 (44.3%) contained an underdeveloped abstract. Articles with underdeveloped abstracts were approximately twice as likely to be rejected than were articles with developed abstracts. Finally, 34.3% of the articles contained information in the abstract (e.g., purpose statement, sample size, findings) that was inconsistent with information provided elsewhere in the article.
