Objective To assess the effectiveness and safety of one kind of ACEI—Ramipril, for providing proofs for clinical implement and we also tried to explore the practical method of evidence-based drug assessment. Method By using the methods and principles of systematic review (SR), and health technology assessment (HTA), we searched Medline and Cochrane Library, together with related materials provided by pharmaceutics and collected all the published clinical research reports on Ramipril. Based on principles of SR and HTA, we assessed all the included reports comprehensively. Results We totally collected 214 articles about Ramipril, in which there were 18 articles meeting the inclusion criteria and 31 139 patients were enrolled in these studies. The research contents include: hypertension, diabetes mellitus, heart failure, myocardial infarction, nephropathy and secondary prevention for cardio-cerebral vascular disease. Conclusion According to our clinical evidence assessment, Ramipril is an effective, safe and easy to take drug and is worthy to spread.
Evidence and its quality are of the key issues in evidence-based medicine. The Cochrane Library is an electronic publication, updated quarterly every year in CD-Rom and internet format, designed to provide high quality evidence to inform people receiving care, and those responsible for treating, teaching, research and administration at all levels. This paper aims to help readers how to access its information as well.
In this paper, we introduce meaning and purpose of confidence interval (CI) in evidence-based medicine, For example, RRR ,ARR ,NNT. It s referance for user and doer of EBM in China.
Medical ethics must be considered for protecting the fights and interests of patients in clinical trials. Now the fights of the subjects are more and more emphasised, but there are some problems. It is evidence-based medicine (EBM) and emphasis of evidence that need the high-quality clinical trials, yet it violates the principle of ethics in some degree. It will be helpful for the administrators to supervise the clinical trials on drugs well from the point of ethical views.
The randomized controlled trial is the best evidence in the evidence-based medicine. The cardiovascular disease internal department is the typical example of the evidence-based medicine. A serial large-scale randomized controlled trials provided the evidence and improved clinical treatment level. For normal development of a large-scale randomized controlled trials need to enhance the standard management.
目的 为避免选择和发表偏倚,系统评价者应采用多种查询技术,并尽力获得未发表的研究.本文试图探讨,英特网检索对鉴定未发表和正在进行的临床试验是否有用.研究设计 利用七个Cochrane系统评价的查询策略回顾性地在英特网上检索未纳入的随机对照试验.方法 检索策略 以普通检索式"研究方法学 NEAR干预措施NERA 条件"、用AltaVista在英特网上搜索.测量指标包括搜索时间、英特网搜索已发表研究的回溯率、精确度(已发表和未发表的随机临床试验链接的网页比例)、英特网检索到的未纳入的未发表和正在进行的研究数.结果 用21小时查询了429个网页,找到14个链接到未发表的、正在进行的或最近完成的试验,至少有9个与4篇系统评价相关.英特网检索已发表研究文献的回溯率在0～43.6%,其链接已发表和未发表研究的精确度在0～20.2%.结论 未发表尤其是正在进行的试验的信息可在英特网上找到.潜在的问题是如何评价未经同行评审的电子出版物的质量.急需更强的搜索工具.建议用"Open Trial Initiative"定义英特网发表试验的语法,以加强试验登记的共同操作性.因此,专门的搜索引擎可找到更多有关正在进行和已完成的临床试验信息.
Evidence-based Chinese medicine is a relatively new discipline which applies the concepts and methods of evidence-based medicine (EBM) to the clinical research and practice of Chinese medicine. It is not only a branch of EBM but also a natural product of the development of Chinese medicine. This paper introduces the theoretical concepts of evidence-based Chinese medicine and reviews the process of its development. It then elucidates the main characteristics of evidence-based Chinese medicine, emphasizes its holistic approach, prescription-syndrome relationship, and its human-centered approach. Research contents and status quo are also summarized to point out the challenges of the production and application of evidence. Finally, we innovatively indicate further research directions on combining individual-based research with population-based research and developing narrative EBM.
Surgery is an accepted standard in the treatment of adenocarcinoma of esophagogastric junction (AEG), but the efficacy of surgery alone for locally advanced AEG is limited. In-depth studies concerning combined therapy for AEG have been carried out worldwide, including neoadjuvant chemotherapy (nCT), neoadjuvant chemoradiotherapy (nCRT), perioperative chemotherapy (pCT), postoperative chemoradiotherapy, etc. Significantly, the contribution of nCRT and pCT to improving the prognosis of locally advanced AEG patients has been shed light on. Compared with that, multimodality treatment for AEG patients is not well established in China. An attempt was thus made to take an overview of the evidence-based research advance regarding integrated therapy of AEG.
Evidence serves as the driving force shifting medical practice from empirical medicine towards evidence-based medicine. In the current era of information explosion, it is challenging for clinical surgeons to extract evidence from the vast pool of primary research literature to address clinical issues. Literature reviews, as a form of synthesized evidence, are particularly crucial for precise and efficient evidence utilization. A new form of review within the framework of evidence-based medicine, systematic reviews, also has widespread application in the surgical domain. With the development of methodological approaches in evidence-based medicine, the types of systematic reviews continue to diversify. This paper outlines and summarizes the common types and methodologies of systematic reviews in the surgical field, aiming to provide a clear framework for surgical practitioners to select evidence for both confirming and innovating clinical practices in specific clinical challenges.
