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

Traditionally, clippings of newspaper articles, pictures from magazines, pamphlets, charts, graphs, posters, proceedings, or copies thereof, and other miscellaneous information sources have been stored in vertical files in libraries. The practice of creating and maintaining vertical files is extremely time consuming. In a medical library, in particular, old information about diagnosis, treatment, and prognosis can quickly become incorrect, misleading, and possibly harmful. Adequately tending to the vertical files can require a librarian to create a balancing act between properly maintaining vertical files and meeting the needs of the users in other areas of the library. The maintenance of vertical files is, by nature, highly consumptive of paper and space consuming. A reasonable alternative to the traditional vertical files is the World-Wide Web. Search engines exist for locating specific information, and bookmarks and/or links which point users to particularly useful sites can be set in search software. Some methods for searching are discussed, and a variety of World-Wide Web information sources are offered. 相似文献

Journal searching in non-MEDLINE resources on Internet Web sites 总被引:1,自引:0,他引:1
Lingle VA 《Medical reference services quarterly》1997,16(3):27-43
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

One of the highest priorities in today's hospitals is the provision of quality care to patients. The medical librarian has an increased responsibility to furnish quality information to the medical staff. Traditional methods of reference service continue to work well, but it is increasingly important for librarians to become more directly involved in hospital quality assurance (QA) activities. Occurrence screening is one system of QA where the librarian can make a difference. 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
