The role of the information specialist in the systematic review process: a health information case study.

There is an increasing body of literature on the information specialist's role in supporting evidence-based health care. In particular, the information component in systematic reviews has received considerable attention in recent years. Information professionals have evolved from simply acting as 'evidence locators' and 'resource providers' to being quality literature filterers, critical appraisers, educators, disseminators, and even change managers. This paper describes ten possible roles for information professionals in the systematic review process, using a case study of a review of the health information needs of visually impaired people carried out by the Centre for Health Information Management Research (CHIMR) at the University of Sheffield. This health information review was undertaken entirely by a team of information professionals. The ten roles identified are: project leader, project manager, literature searcher, reference manager, document supplier, critical appraiser, data extractor, data synthesiser, report writer and disseminator. This review has also identified an eleventh possible role for information professionals; that of primary researcher. Finally, the implications for evidence-based health care and evidence-based health informatics are discussed.
