This article discusses HIV infection in terms of the risk manager's information needs in the health care environment. The malpractice problem, increasing workman's compensation suits, the greater role of the ombudsman, implementation of the National Practitioner Data Bank, and the Joint Commission on Accreditation of Health Care Organizations' (JCAHO) emphasis on clinical excellence are conditions which have given greater importance to the risk manager's position. Included in this article are hedges to retrieve various components of risk management and a select bibliography from AIDSLINE.  相似文献

This study explores faculty deposits in institutional repositories (IR) within selected disciplines and identifies the diverse navigational paths to IR sites from library Web site homepages. The statistical relationship between the development of an IR and the presence of a Web site dedicated to the reform of traditional scholarly communication is also explored. The implications for the development of institutional repositories are highlighted.  相似文献

The purpose of the study was to identify the pattern of publication about women and AIDS in scientific journals. Bradford zones were identified in each of six databases. The study determined that journal scatter for this subset of AIDS literature differed from the scatter in the general literature; further, the information indexed in the six electronic sources demonstrated little overlap. Consequently, key journal and newsletter titles identified by this study should form the core of any collection focusing on women and AIDS. The assurance of quality patient care management demands that librarians consult multiple resources for information retrieval that can assist health care providers, patients, and caregivers to enhance quality of life as well as to provide optimum care.  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
