Interventions for family members caring for an elder with dementia.

This chapter reviews 73 published and unpublished research reports of interventions for family members caring for an elder with dementia by nurse researchers and researchers from other disciplines. Reports were identified through searches of MEDLINE, CINAHL, Social Science Index, PsycINFO, ERIC, Social Work Abstracts, American Association of Retired Persons database, CRISP index of the National Institutes of Health, Cochrane Center database, and Dissertation Abstracts using the following search terms: caregiver, caregiving, dementia, Alzheimer's, intervention study, evaluation study, experimental, and quasi-experimental design. Additional keywords were used to narrow or expand the search as necessary. All nursing research was included in the review and nonnursing research was included if published between 1991 and 2001. Studies were included if they used a design that included a treatment and control group or a one-group, pretest-posttest design (ex post facto designs were included if they used a comparison group). Key findings show that approximately 32% of the study outcomes (e.g., burden, depression, knowledge) were changed after intervention in the desired direction. In addition, several problematic issues were identified including small, diverse samples; lack of intervention specificity; diversity in the length, duration, and intensity of the intervention strategies; and problematic outcome measures.

Active index for content-based medical image retrieval.

This paper introduces the active index for content-based medical image retrieval. The dynamic nature of the active index is its most important characteristic. With an active index, we can effectively and efficiently handle smart images that respond to accessing, probing and other actions. The main applications of the active index are to prefetch image and multimedia data, and to facilitate similarity retrieval. The experimental active index system is described.

Mapping the literature of nurse practitioners.

OBJECTIVES: This study was designed to identify core journals for the nurse practitioner specialty and to determine the extent of their indexing in bibliographic databases. METHODS: As part of a larger project for mapping the literature of nursing, this study followed a common methodology based on citation analysis. Four journals designated by nurse practitioners as sources for their practice information were selected. All cited references were analyzed to determine format types and publication years. Bradford's Law of Scattering was applied to identify core journals. Nine bibliographic databases were searched to estimate the index coverage of the core titles. RESULTS: The findings indicate that nurse practitioners rely primarily on journals (72.0%) followed by books (20.4%) for their professional knowledge. The majority of the identified core journals belong to non-nursing disciplines. This is reflected in the indexing coverage results: PubMed/MEDLINE more comprehensively indexes the core titles than CINAHL does. CONCLUSION: Nurse practitioners, as primary care providers, consult medical as well as nursing sources for their information. The implications of the citation analysis findings are significant for collection development librarians and indexing services.

The biomedical information explosion: from the index-catalogue to MEDLARS.

This study demonstrates the growth of medical periodical literature by means of the increase of titles indexed in the Index-Catalogue and in Index Medicus, with reference to other biomedical-related titles not covered in these publications. Stress is laid on the fact that information outside the biomedical area is needed by the researcher. Problems of information retrieval, with the specific needs of the user in mind, are discussed, together with the particular problems of indexing which this specificity raises.

What the Index Medicus indexes, and why.

The main criterion for selecting journals for indexing in Index Medicus, and thereby largely in MEDLARS, is quality. Subject scope varies with the voiced needs of the biomedical community. The Index aims to cover the best journals in all relevant subject fields, but the percentage of journals on a subject indexed depends on the quality of each journal. Country and language coverage depends on quality, even in the case of the best journals of each, although American biases may affect such selection. While a number of guidelines exist for identifying quality journals, information necessary to apply them confidently is often difficult to obtain. The National Library of Medicine is advised by an Ad Hoc Panel on the Selection of Journals for Index Medicus, composed both of NLM officers and extramural members. Criticism has been voiced that too many titles are indexed, compared with titles actually used, but no meaningful statistics of use exist which can identify titles which should be excluded from indexing. Continuing suggestions from users regarding titles indexed would benefit everyone.

INVERTED INDEXING ON EDGE-NOTCHED CARDS.

Edge-notched cards in an inverted system of indexing may be used satisfactorily to analyze research data which concern a small series of individuals but a large number of highly variable characteristics in a short-term research project.
