MEDLARS: A computerized biomedical bibliographic storage and retrieval system operated by the NATIONAL LIBRARY OF MEDICINE. MEDLARS stands for Medical Literature Analysis and Retrieval System, which was first introduced in 1964 and evolved into an online system in 1971 called MEDLINE (MEDLARS Online). As other online databases were developed, MEDLARS became the name of the entire NLM information system while MEDLINE became the name of the premier database. MEDLARS was used to produce the former printed Cumulated Index Medicus, and the printed monthly Index Medicus, until that publication ceased in December 2004.National Library of Medicine (U.S.): An agency of the NATIONAL INSTITUTES OF HEALTH concerned with overall planning, promoting, and administering programs pertaining to advancement of medical and related sciences.

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.  (+info)

Efficacy of metformin in the treatment of NIDDM. Meta-analysis. (2/117)

OBJECTIVE: The results differ concerning randomized controlled trials of the effects of metformin on blood glucose regulation and body weight. To get a systematic overview, a meta-analysis of the efficacy of metformin was performed by comparing metformin with placebo and sulfonylurea. RESEARCH DESIGN AND METHODS: All randomized controlled trials published since 1957 were selected by searching the Current List of Medical Literature, Cumulated Index Medicus, Medline, and Embase, Meta-analysis was performed calculating weighted mean difference (WMD) of fasting blood glucose, glycosylated hemoglobin, and body weight. RESULTS: Nine randomized controlled trials comparing metformin with placebo and ten comparing metformin with sulfonylurea were identified. The WMD between metformin and placebo after treatment for fasting blood glucose was -2.0 mmol/l (95% CI -2.4 to -1.7) and for glycosylated hemoglobin -0.9% (95% CI -1.1 to -0.7). Body weight WMD was not significant after treatment. Sulfonylurea and metformin lowered blood glucose and glycosylated hemoglobin equally, while there was a significant WMD of body weight (-2.9 kg [95% CI -4.4 to -1.1]) because of a 1.7-kg mean increase after sulfonylurea and a 1.2-kg mean decrease after metformin. CONCLUSIONS: Metformin lowers blood glucose and glycosylated hemoglobin significantly, compared with placebo. Metformin and sulfonylurea have an equal effect on fasting blood glucose and glycosylated hemoglobin, but the body weight is significantly lower after metformin compared with sulfonylurea treatment because of an increase in body weight after sulfonylurea treatment.  (+info)

Which literature retrieval method is most effective for GPs? (3/117)

BACKGROUND: Evidence-based medicine requires new skills of physicians, including literature searching. OBJECTIVE: To determine which literature retrieving method is most effective for GPs: the printed Index Medicus; Medline through Grateful Med; or Medline on CD-ROM. METHODS: The design was a randomized comparative study. In a continuing medical education course, three groups of health care professionals (87 GPs and 16 other health care professionals) used one of the literature retrieval methods to retrieve citations on four search topics related to general practice. For the analysis in pairs, we used the search results of the 75 participants who completed all four assignments. As outcome measures, we used precision, recall and an overall search quality score; we also had a post-course questionnaire on personal characteristics, experience with computers, handling medical literature and satisfaction with course instruction and search results. RESULTS: The recall and overall search quality scores in the Index Medicus groups (n = 32) were higher (P = <0.001) than those in the CD-ROM groups (n = 31). In addition, the search quality scores in the Grateful Med groups (n = 12) were higher (P < 0.003) than those in the CD-ROM groups. There were no differences in precision. CONCLUSION: In the period 1994-1997, the printed Index Medicus was the most effective literature retrieval method for GPs. For inexperienced GPs, there is a need for training in electronic literature retrieval methods.  (+info)

The evolution of rural outreach from Package Library to Grateful Med: introduction to the symposium. (4/117)

Outreach is now a prevailing activity in health sciences libraries. As an introduction to a series of papers on current library outreach to rural communities, this paper traces the evolution of such activities by proponents in health sciences libraries from 1924 to 1992. Definitions of rural and outreach are followed by a consideration of the expanding audience groups. The evolution in approaches covers the package library and enhancements in extension service, library development, circuit librarianship, and self-service arrangements made possible by such programs as the Georgia Interactive Network (GaIN) and Grateful Med.  (+info)

The use of information technology in improving medical performance. Part III. Patient-support tools. (5/117)

Despite the proliferation of computer-based resources for patients, usefulness has been limited to date. Already, 17,000 biomedical Internet sites exist, and patients are increasingly finding support and knowledge on the Internet, but the accuracy of the information found is highly variable and difficult for patients to assess. Patients have also found value in electronic communication with physicians, although relatively few physicians routinely use email to communicate with patients on a regular basis. Nonetheless, patient-focused information technologies potentially will have profound effects on medical care. With advancing sophistication of technology, patients will increasingly be able to compare and choose doctors using the Internet and to access information that allows them to monitor and regulate the quality of their own care. Further, technologies will likely be developed to allow patients to increasingly manage their own care -- whether they are patients with chronic illnesses such as diabetes or congestive heart failure who use customized software to adjust drug dosages and other treatments or patients with such common illnesses as headache or gastrointestinal infection who access self-management programs that may even write prescriptions for them. Thoughtful analysis and policy development will be critical for ensuring that the benefits are maximized and potential harm minimized. Specific areas include assessing the effects on outcomes and the characteristics of patients and technologies that succeed with self-management, and developing policies regarding liability for Web-based medical transactions and the privacy of information provided to physicians by email and via interactive Web sites.  (+info)

A rural virtual health sciences library project: research findings with implications for next generation library services. (6/117)

PURPOSE: The Shared Hospital Electronic Library of Southern Indiana (SHELSI) research project was designed to determine whether access to a virtual health sciences library and training in its use would support medical decision making in rural southern Indiana and achieve the same level of impact seen by targeted information services provided by health sciences librarians in urban hospitals. METHODS: Based on the results of a needs assessment, a virtual medical library was created; various levels of training were provided. Virtual library users were asked to complete a Likert-type survey, which included questions on intent of use and impact of use. At the conclusion of the project period, structured interviews were conducted. RESULTS: Impact of the virtual health sciences library showed a strong correlation with the impact of information provided by health sciences librarians. Both interventions resulted in avoidance of adverse health events. Data collected from the structured interviews confirmed the perceived value of the virtual library. CONCLUSION: While librarians continue to hold a strong position in supporting information access for health care providers, their roles in the information age must begin to move away from providing information toward selecting and organizing knowledge resources and instruction in their use.  (+info)

A quantitative ranking of Canada's research output of original human studies for the decade 1989 to 1998. (7/117)

BACKGROUND: Since 1987 research articles have been catalogued with the author's affiliation address in the 40 databases of the Medical Literature Analysis and Retrieval System (MEDLARS) of the National Library of Medicine, Bethesda, Md. The present study was conducted to examine the Canadian entries in MEDLARS to interpret past and future trends and to combine the MEDLARS demographic data with data from other sources to rank Canadian research output of human studies both nationally and internationally. METHODS: The PubMed Web site of the National Library of Medicine was used to count medical articles archived in MEDLARS and published from Jan. 1, 1989, through Dec. 31, 1998. The articles attributed to Canadian authors were compared by country, province, city, medical school, hospital, article type, journal and medical specialty. RESULTS: During the study period Canadian authors contributed on average 3% (standard deviation [SD] 0.2%) of the worldwide MEDLARS content each year, which translated to a mean of 11,067 (SD 1037) articles per year; 49% were human studies, of which 13% were clinical or controlled trials, and 55% involved people aged 18 years or less. In total, 68% of the articles were by authors affiliated with Canadian medical schools; those affiliated with the University of Toronto accounted for the greatest number (8604), whereas authors affiliated with McGill University had the greatest rate of annual increase in the quantity published (8%). Over one-third (38%) of the articles appeared in Canadian journals. When counted by specialty, 17% of the articles were by authors with clinical specialties, 5% by those with surgical specialties and 3% by those with laboratory specialties. INTERPRETATION: The annual rate of increase in research output for Canada was more than 3 times higher than that seen world wide. Canada is now ranked seventh among countries contributing human studies to MEDLARS. The increase indicates that Canada's medical schools are productive, competitive in making contributions to medical science and are supporting Canadian journals.  (+info)

Medical subject headings used to search the biomedical literature. (8/117)

The National Library of Medicine's MEDLINE (MEDLARS Online) database was the first database to be searched nationwide via value-added telecommunication networks. Now available on the World Wide Web free of charge from the National Library of Medicine and from many other sources, it is the world's most heavily used medical database. MEDLINE is unique in that each reference to the medical literature is indexed under a controlled vocabulary called Medical Subject Headings (MeSH). These headings are the keys that unlock the medical literature. MeSH multiplies the usefulness of the MEDLINE database and makes it possible to search the medical literature as we do today. This paper commemorates the 40th anniversary of the introduction of MeSH and salutes some of the farsighted persons who conceived and developed the MEDLINE database.  (+info)
