Coverage of sixty core veterinary medical journals by ten indexing and abstracting tools.

Ten indexing and abstracting reference sources were examined for their coverage of 60 core veterinary medical journals. The costs of the indexes also were compared. Coverage of the 60 core veterinary journals ranged from 8 of 60 journals by Current Contents--Life Sciences to 57 of 60 by Index Veterinarius. Based on yearly costs, format, and coverage of the 60 core veterinary journals, Small Animal Practice and the 2 editions of Veterinary Reference Service were determined to be the most useful for private practitioners. The Index Veterinarius gives the most complete coverage of the core veterinary journals for veterinary research workers who have access to a library.

Journal article overlap among Index Medicus, Science Citation Index, Biological Abstracts, and Chemical Abstracts.

Journal article overlap is defined as the same journal article being indexed by two or more services. Using journal references from seventy dissertations written in the preclinical sciences, the extent of journal article overlap among Index Medicus, Science Citation Index, Biological Abstracts, and Chemical Abstracts was examined. Of the 7,969 journal references cited, 92% were indexed by at least two of these services; 591 articles were covered by only one of the services, and 55 articles were not indexed. A discussion of the advantages and costs of journal article overlap is presented.

The evaluation of published indexes and abstract journals: criteria and possible procedures.

This paper describes possible criteria by which the effectiveness of a published index may be evaluated and suggest procedures that might be used to conduct an evaluation of a published index. The procedures were developed for the National Library of Medicine and relate specifically to the recurring bibliographies produced by MEDLARS in various specialized areas of biomedicine. The methods described should, however, be applicable to other printed indexes and abstract journals. Factors affecting the performance of a published index are also discussed and some research projects relevant to the evaluation of published indexes are reviewed.

CHEMFILE: an in-house information system for the chemical indexing of Abstracts on Health Effects of Environmental Pollutants (HEEP).

The inclusion of a Chemical Abstracts Service (CAS) Registry Number index in HEEP has led to the need for a special database designed to link substance names with their appropriate CAS chemical compound Registry Numbers. Begun in 1968 as a tape record with batch mode updates and few record modification capabilities, the information system, which we call CHEMFILE, has evolved to its current form of disk storage with on-line access for file maintenance.

Interventions for preventing falls in the elderly.

BACKGROUND: Fractures in the elderly often result from a simple fall. OBJECTIVES: To assess the effects of programmes designed to reduce the incidence of falls in community dwelling, institutionalised, or hospitalised elderly people. SEARCH STRATEGY: We searched MEDLINE, EMBASE, CINAHL, PsycLIT, Social Science Citation Index, Dissertation Abstracts, Index to UK Theses, the Cochrane Register of Controlled Trials, and bibliographies of identified studies. We contacted known workers in the field. Trials were also obtained from the Cochrane Musculoskeletal Injuries Group trials register. Date of the most recent search: May 1997. SELECTION CRITERIA: Randomised trials of interventions designed to minimise the effect of, or prevent exposure to, any putative risk factor for falling in elderly individuals living in the community, in institutional care, or in hospital. The main outcomes of interest were number of fallers or falls, or the number sustaining a fall resulting in injury. Trials that focused on intermediate outcomes such as improved balance or did not report fall outcomes, were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers selected trials for inclusion. For each included trial, quality assessment and data extraction was carried out independently by two reviewers. Results of trials of similar design were pooled. MAIN RESULTS: Eighteen trials and one pre-planned meta-analysis were included. The analysis of four trials which studied the effect of exercise alone did not establish protection against falling (Peto odds ratio 1.05; 95% confidence interval 0.74 to 1.48). Based on one trial, there was no evidence to support exercise in conjunction with health education classes (Peto odds ratio 1.72; 95% confidence interval 0.78 to 3.75), or of health education classes alone (Peto odds ratio 1.25; 95% confidence interval 0.51 to 3.03) for the prevention of falls. However, significant protection against falling was apparent from interventions which targeted multiple, identified, risk factors in individual patients (Peto odds ratio 0.77; 95% confidence interval 0. 64 to 0.91), and from interventions which focused on behavioural interventions targeting environmental hazards plus other risk factors (Peto odds ratio 0.81; 95% confidence interval 0.71 to 0.93). REVIEWER'S CONCLUSIONS: Health care purchasers and providers contemplating fall prevention programmes should consider health screening of at risk elderly people, followed by interventions which are targeted at both intrinsic and environmental risk factors of individual patients. There is inadequate evidence for the effectiveness of single interventions such as exercise alone or health education classes for the prevention of falls.

Alternative sources of drug information: indexing and abstracting systems.

The proliferation of information and literature in medicine, therapy, and pharmacy practice in general has created a need for a centralized source of indexing that enables individuals to efficiently locate this type of literature. An excellent example of this type of system would be Index Medicus. But Index Medicus is voluminous and all-encompassing in its coverage. The need for fast, convenient access to publications in specialty areas has led to decentralized specialty indexing and abstracting systems that deal with a particular area of medicine, therapy, or pharmacy practice. This article deals with these specialty systems and encourages their investigation and use when searching the literature.
