ABSTRACT

Background: Intravenous thrombolysis with fibrinolytic drugs such as alteplase is not implemented widely in any country although the treatment is both effective and cost-effective in selected patients within a 3-h window after acute ischaemic stroke. The purpose of the present study was to describe the organisational barriers to delivery of thrombolysis for acute ischaemic stroke with special regard to the Danish healthcare system.

Method: Systematic and unsystematic searches of medical, economic and grey literature on organisational barriers to thrombolysis treatment were performed in Cochrane, PubMed, EMBASE, Cinahl, Econlit, NHS EED, SvedMed+ and the Health Technology Assessment (HTA) database. The search periods were 1996-2006.

Findings: Three main types of literature on organisational barriers were found: medical literature including HTA reports on barriers related to the 3-h window, economic literature on barriers related to the lack of capacity to provide the treatment on a 24-h basis, and grey literature/policy papers on standards and demands to the hospitals and healthcare systems who implements the treatment.

Conclusion: Information on organisational barriers can be extracted from different types of literature (medical, economic and grey literature/policy papers), but organisational barriers are most often not the primary study objective in the relevant literature. This review showed a broad spectrum of possible organisational barriers to the delivery of thrombolysis treatment of acute ischaemic stroke.  相似文献

Objectives. To design and implement a cardiovascular pharmacotherapy elective course to enhance pharmacy students’ ability to evaluate medical literature and apply clinical evidence.Design. In weekly class sessions, students were provided an overview of the important literature supporting therapeutic guidelines for the management of major cardiovascular diseases. Students worked in groups to complete outside-of-class assignments involving a patient case and then discussed the case in class. During the semester, each student also independently completed a literature search on an assigned topic, summarized the studies found in table format, and presented 1 of the studies to the class.Assessment. Students’ grades on weekly patient case assignments steadily increased over the semester. Also, the average grade on the final examination was higher than the grade on the midterm take-home examination. On the course evaluation, students rated the course favorably in terms of improvement of confidence in evaluating the primary literature and applying it to practice.Conclusion. Completion of the cardiovascular pharmacotherapy elective increased pharmacy students’ level of confidence in evaluating literature and applying clinical evidence in making patient care decisions.  相似文献

Although striking ethnic differences in pharmacologic responses to various medications have been documented in the general medical literature, there is a paucity of such information in the psychopharmacologic literature. Recent work has provided a number of studies that illustrate interesting inter-ethnic pharmacogenetic, pharmacokinetic, and pharmacodynamic differences. In general, however, such studies have reported inconsistent findings relative to dose response relationships with various psychotropics. Results of our literature review, with a particular focus on black Americans, suggest that the lack of consistency in these investigations is largely attributable to various methodological and design problems. Prominent among these problems are: diagnostic misclassification, treatment of various ethnic groups in a homogeneous undifferentiated manner, lack of appropriate control for age and gender, and minimal consideration for chronicity of illness. As a result, though there exist some interesting data suggesting inter-ethnic genetic and kinetic differences, the extant literature on black Americans and other ethnic groups should be evaluated with some caution. The purpose of this article is to provide a systematic review of the existing psychopharmacologic literature on the black American population.  相似文献

An awareness of how and where to search the education literature, and how to appraise it is essential to be a teacher scholar (an academic who takes a scholarly approach to teaching), to develop high quality education research, and to perform the scholarship of teaching and learning. Most pharmacy faculty scholars do not receive training in searching the education literature. Thus, a framework for searching the education literature is needed. The framework presented here on where and how to search for evidence in the education literature, referred to as the WHEEL for teaching, is meant to serve as a guide for faculty members in conducting comprehensive and exhaustive literature searches for the publication of scholarship of teaching and learning projects, educational research, or approaching one''s teaching in a scholarly manner. Key resources to search and methods for searching the education literature are listed and described.  相似文献

《文心雕龙.时序》是一篇专门论述文学发展与时代演变关系的论文。在这篇文章里,作者认为政治教化与时代风气、学术风气、统治者的态度都可以对文学发展的方向、内容、风格产生一定影响。刘勰生活在南朝宋、齐、梁时期,其时代风气、统治者对文学的态度都恰好印证了他的观点。当时的文坛追求新奇、绮丽浮夸的风气盛行,虽然刘勰对这种文风极为不满,并力图创作《文心雕龙》来矫正这一流弊,但从作者实际创作情况来看,却难以摆脱其影响。  相似文献
