Searching bibliographic databases effectively

HEALTH POLICY AND PLANNING 1998年第3期13卷 339-342页

作者： Eyers, JE Univ London London Sch Hyg & Trop Med London WC1E 7HT England

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.

The quality and impact of MEDLINE searches performed by end users.

Health libraries review 1995年第3期12卷 191-200页

作者： McKibbon, K.A. Walker-Dilks, C.J. Department of Clinical Epidemiology and Biostatistics Faculty of Health Sciences McMaster University Hamilton Ontario Canada

Evidence suggests that MEDLINE is becoming an important clinical tool that can improve the care and health of patients. Efforts to improve the quality and impact of end-user searching are needed and ongoing. End users are completing many MEDLINE searches. They appreciate and value training along with feedback on their searching techniques. Practice, is however, the biggest single factor in improving the quality of searching. Key roles for the library in end-user searching include, providing the most effective MEDLINE access possible to the maximum number of users, and providing training that includes feedback and practice opportunities. System-wide advances in structured abstracts, indexing, system design, informatics research and the literature itself will make searching easier and more effective in the future. More important than the quality of search results per se is the impact that end-user searches have on patient care and patient outcomes. Growing evidence shows that both patient care and patient outcomes are improved by end-user searches.

Managing patient demographics.

Journal for healthcare quality : official publication of the National Association for Healthcare Quality 1994年第1期16卷 18-21;quiz21,48页

作者： Baumstein, C. Block, S. Whitworth, J. Kenmore Center of Harvard Community Health Plan Boston MA

The Harvard Community Health Plan commissioned a cross-functional project team to improve the accuracy of the members' data base because inaccurate patient phone numbers and addresses were a major obstacle for clinicians seeking to provide high-quality service to patients. Accurate demographic information is essential to enable clinicians to contact patients quickly regarding lab results or follow-up care. The team members applied a quality improvement problem-solving methodology that required them to focus on the few vital problems and to test problems using data analysis. As a result, the team saw firsthand that staff members were not to blame for the inaccurate demographic information;the problem was in the automated system that obtains, updates, and maintains the records.

Designing a search strategy to identify and retrieve articles on evidence-based health care using MEDLINE.

引用

Health libraries review 1997年第1期14.0卷 33-42页

作者： Harrison, J. School of Health and Related Research (ScHARR) University of Sheffield United Kingdom

The practice of evidence-based health care requires that information on methodology be identified from databases such as MEDLINE. Up until this year there have been no designated medical subject headings (MeSH) for evidence-based health care. 'EVIDENCE-BASED MEDICINE' appears as a MeSH term from 1997. The absence of designated MeSH for this concept prior to 1997 provides a challenge to the searcher. This paper describes the creation of a MEDLINE search strategy to retrieve articles on the methods of evidence-based health care published prior to the introduction of the new term, where an optimal combination of free-text and MeSH terms is required to identify relevant material. The study examines both free-text and subject heading searching and attempts an optimal balance of sensitivity and specificity. It begins by examining separate free-text and subject heading searches. Sensitivity of the subject heading search was 33% and specificity 80%, while the free-text search produced a sensitivity of 50% and a specificity of 67%. The final strategy, combining both approaches, was more successful with sensitivity reaching between 82 and 90% and specificity 83%. It is therefore possible to devise a search strategy to retrieve articles on the methods of evidence-based health care with relatively successful rates of sensitivity and specificity. The limitations of MEDLINE, however, necessitate the use of additional approaches in identifying articles on the methods of evidence-based health care.

Quality assurance in health sciences literature searching: applying the ISO 9000 quality standard.

引用

Health libraries review 1995年第3期12卷 173-189页

作者： Cullen, R. Mason, D. Department of Library and Information Studies Victoria University Wellington New Zealand

Medicine is a literature-based discipline. Ensuring that the literature review which precedes a significant piece of medical research has met predetermined standards is essential. A list of items reviewed carries no guarantees that all appropriate items have been included in the survey of the literature, or that appropriate sources have been efficiently searched. This would be a matter for concern in any discipline. In medicine it is a matter of life and death. Quality assurance procedures that offer guarantees of the standards built into the process, rather than quality control which measures only outputs, can provide the necessary reassurance. The ISO 9000 quality standard offers a much needed quality assurance process. A methodology for applying the ISO 9000 standard to the task of searching the medical literature is outlined in this paper. A new role for medical librarians in promoting a rigorous methodology in the literature review equal to that of the research it supports is defined.

Criteria for evaluating alternative MEDLINE search engines

引用

Medical Reference Services Quarterly 1998年第3期17卷 1-12页

作者： Jacobs, Maggie Edwards, Alice Graves, Rebecca S. Johnson, E. Diane J. Otto Lottes Health Sciences Library University of Missouri-Columbia Columbia MO 65212 United States

With so many options available for searching MEDLINE on the World Wide Web or as a component of an online service, evaluation criteria are suggested as a means of assisting librarians in determining the positive and negative aspects of alternative MEDLINE sites. A set of searches was utilized to systematically compare MEDLINE sites. Sites evaluated included Avicenna, America Online, HealthGate, PubMed, Medscape, and Physicians’ Online. Some features used to evaluate these sites were: default fields;operators (default);access to MeSH;subheadings;stop words protected in MeSH;truncation;and stemming. This article will describe the group process used to arrive at the evaluation criteria, as well as some general conclusions which will help librarians in directing their users to a particular MEDLINE site. © 1998 by The Haworth Press, Inc.

Who's been using my CD-ROM? Results of a study on the value of CD-ROM searching to users in a teaching hospital library.

引用

Health libraries review 1995年第1期12卷 39-52页

作者： Dyer, H. Buckle, P. formerly of: Department of Information and Library Studies Loughborough University Loughborough Leicestershire LE11 3TU

cd-rom systems are heavily used in medical libraries, but literature on the topic reports that searching is of poor quality. There is increasing concern over doctors' legal liability for their patients and the role of the literature search in keeping doctors informed. Will poor searching impact on the quality of information retrieved? This small-scale study was a pilot for a larger investigation which has been sponsored by the British Library. Findings indicate that, while searching is inelegant, it is not necessarily ineffective, although it would appear that medical practitioners would find training in the use of cd-rom systems cost-effective.

Teaching information literacy skills: an evaluation

引用

NURSE EDUCATION TODAY 2000年第6期20卷 485-489页

作者： Wallace, MC Storten, A Crookes, PA Univ Wollongong Dept Nursing Wollongong NSW 2522 Australia

This paper describes an evaluation of a curriculum-integrated information literacy programme in an undergraduate nursing course. The aim of the programme was to provide students with an awareness of the discipline's literature and the skills to locate and retrieve the literature. A multidimensional process for determining nursing students' development was utilised in the evaluation of the programme. Pre- and post-programme questionnaires were distributed to a cohort of students who undertook the programme. A cohort of more senior students who had not undertaken the information literacy programme was utilised as a comparison group. Questionnaire results were analysed using a range of inferential statistics. This paper will focus on two main findings related to objective measures of information literacy skills. These include pre-programme/post-programme change in student performance and differences in student performance between those who undertook the programme and those who did not. The programme demonstrated its effectiveness in developing information literacy skills, however the challenge remains for both academics and students to ensure that these skills are consolidated and extended for effective life-long learning.

Using evaluation research methods to improve quality.

引用

Health libraries review 1995年第3期12卷 159-172页

作者： Marshall, J.G. Faculty of Information Studies University of Toronto Canada

The idea of evaluation, or the measurement of a person, a service or a programme against some type of yardstick, has been around for a long time. In everyday language, the term evaluation is used to refer to everything from employee performance appraisal, to informal opinions about whether a particular service appears to be working well, to carefully planned and executed programmes of evaluation. In the past, librarians have tended to rely on their own professional judgement as a primary means of informal evaluation, and as long as the librarian was considered competent by others in the organization, this method seemed to work reasonably well. In the rapidly changing fiscal climate of the 1990s, greater demands for accountability are altering the standards of evaluation, and informal methods based on professional judgement are less and less likely to be seen as adequate. Formal evaluation is becoming even more important as management strategies, such as total quality management (TQM) and continuous quality improvement (CQI), are adopted--strategies that rely on gathering and using data for measuring service quality. Although programme jargon such as TQM and CQI may change in the future, it is likely that the evaluation process inherent in these approaches will continue to be an important management tool for deciding on the allocation of scarce resources.
