Benchmarking is a quality improvement tool that is increasingly being applied to the health care field and to the libraries within that field. Using mostly resources assessible at no charge through the Internet, a collection of information was compiled on benchmarking and its applications. Sources could be identified in several formats including books, journals and articles, multi-media materials, and organizations.  相似文献

Before planning for provision of Consumer Health Information Services, the librarian and administration must anticipate the problems encountered in sharing funds, personnel, space, and materials with an existing medical or patient education library. Establishing new space within or outside the hospital, or participating in community projects which meet consumer health information needs, are important considerations for planners. This article sets forth the place of some CHI services in the hospital setting, and how they relate to other library services. Differences between hospital library support for Patient Education and for Consumer Health Information services are discussed.  相似文献

Journal searching in non-MEDLINE resources on Internet Web sites   总被引:1,自引:0,他引:1  
Internet access to the medical journal literature is absorbing the attention of all relevant parties, i.e., publishers, journal vendors, librarians, commercial providers, government agencies, and end users. Journal content on the Web sites spans the range from advertising and ordering information for the print version, to table of contents and abstracts, to downloadable full text and graphics of articles. The searching parameters for systems other than MEDLINE also differ extensively with a wide variety of features and resulting retrieval. This discussion reviews a selection of providers of medical information (particularly the journal literature) on the Internet, making a comparison of what is available on Web sites and how it can be searched.  相似文献

In order to assess the current status of MEDLINE training provided by schools of library science, a survey was conducted of those schools having an educational identification code issued by the National Library of Medicine. Information was gathered on such variables as the instructors' background and preparation, the course objectives and content, and the amount of on-line experience provided to students in each of eleven programs. An evaluation of these measures indicates that more opportunities to gain experience in using MEDLINE should be initiated by library schools and that current efforts should be continued and expanded. Specific recommendations for accomplishing these goals are outlined; they are addressed to health sciences librarians, library school educators, the Medical Library Association, and the National Library of Medicine.  相似文献
