Objectives: Map of Medicine is an evidence‐based online clinical knowledge resource. Procured at significant cost by healthcare providers in the UK, Sweden and Denmark, it is important to establish the beneficial impact that investment has had on healthcare practise and, ultimately, on patient outcomes. The objective of this study is to review the evidence for the impact of the Map of Medicine on clinical practice. Methods: A systematic review of peer‐reviewed and grey literature was conducted. Nine healthcare databases, Google Scholar and Google were searched for articles containing the terms ‘map of medicine’. Results: The search identified 133 articles. Eleven of the articles identified met the inclusion criteria. The main finding of the study is the paucity of evidence available on the impact of the Map of Medicine and the variable quality of that which does exist. There are some encouraging early indications for the Map of Medicine as a tool within service redesign, leading to an increase in appropriate referrals to secondary care, decreased patient waiting times and considerable cost savings. Conclusion: Further research with study designs that can generate high quality evidence for the impact of Map of Medicine is essential in order to support policy decisions. 相似文献

Between Desires and Beliefs: Young Children's Action Predictions 总被引:2,自引:0,他引:2
Karen Bartsch 《Child development》1996,67(4):1671-1685
1 view of children's developing understanding of mind contends that children adopt a succession of naive psychological theories, moving from a desirefocused theory to a mature theory that attributes a greater role to beliefs. Between these, a transition theory, in which desires are primary but beliefs play an auxiliary role, is characteristic. Novel predictions arising from this view were tested in 2 experiments utilizing within participants designs. Preschool children ( N s = 20 and 24) were asked to predict the actions of story characters who believed a desired object to be in one of two containers (which were shown to actually contain the desired object, nothing, or a different object). In both experiments, children's predictions accorded with belief significantly more when objects of the type desired were in both containers than when containers held nothing or other sorts of objects, supporting a transition theory interpretation over competing interpretations. 相似文献

Many libraries have sought the best approach to allocating the collections budget. “History plus increment” is the standard for many libraries in the allocation of any new dollars to collections budgets. Other libraries have identified factors that help make the process of disbursing new money more objective including counts of faculty and students, literature size and costs, and program changes on campus.The Library of the University of Illinois at Urbana-Champaign is striving toward a more open and understandable allocation process that uses an allocation formula, professional judgment of its librarians, and input from campus faculty and administration. Through this process, we work to achieve balance between formula and professional judgment, between decisions made outside the Library and within the Library, between competing disciplines and old and emerging fields for budget dollars. 相似文献
