Objective We searched the Cochrane Library（Issue 3, 2005 ）to identity evidence related to palliative treatment. We found that Opioids are effective for the palliation of breathlessness in terminal illness. Oral Morphine and hydromorphone is effective for cancer pain. Radiotherapy and Bisphosphonates can relief pain secondary to bone metastases. Corticosteroids can resolve malignant bowel obstruction in advanced gynaecological and gastrointestinal cancer.
Testing Treatments is a book to help the public understand how to validate the efficacy of testing treatments and the possible bias and error in clinical trial, as well as to call for help to promote good study thus to improve the quality of health care. No matter for the first or the second edition, this book is very popular around the world, and its second edition has been translated into more than ten languages. To help the readers understand the content of the book, we established a website (www.testingtreatments.org) and other sibling sites in different languages. The website not only provided the full-texts to download, but also collected various popular science resources (videos, audios and cartoons) to help the readers assimilate more knowledge. The editors of all the different language websites have established an TTi Editorial Alliance to share experience and provide each other with mutual support, thus to promote health professionals, patients and public around the world to use reliable research to inform their health decisions.
Objective To explore the effect of applying evidence-based medicine theory to quality management in long-term-system clinical medicine teaching. Methods We introduced the concept of evidence-based quality management system of clinical medicine to the delivery of teaching with Internet-based teaching quality real time supervision system as the core. A special quality scale was used to assess the teaching quality of teachers and the results were analyzed by SPSS 10.0 using u test. Results The system stored 853 280 pieces of data from the years 2001 to 2003. Up to 96.4% (275/285) of the evaluated topics scored over 85 points. Whether the teachers had overseas experience or not and whether their ages were over 45 or not had no significant influence on the teaching quality (P ＞0.05), but their degrees had influence on the teaching quality (P ＜0.05). Conclusion In long-term-system clinical medicine teaching quality management, we should apply the concept and approach of EBM to our practice so that we can ensure that the teaching quality of long-term-system clinical medicine will improve steadily.
Literature bias, which can reduce the validity of a systematic review, comes mainly from the fact that all the related studies can not be collected without exception. The following three types of literature bias are most common. (1) Publication bias. The reason is that some studies can not get published, or the publication has been delayed. (2) Literature retrieval bias. This bias is the result that not all published studies are retrieved during the course of systematic review. (3) Literature inclusion bias. While an improper literature selection strategy is adopted, some useful studies are kicked out by error, leading to such bias. A funnel plot (Y-axis is rumple size, X-axis effect) is usually useful to assess literature bias in a systematic review.
Evidencebased medicine (EBM) is different fromtraditional medicine in that the practice of EBM comes from evidence and experience of the doctors. The objective evidence plays a key role in clinical practice. During the clinical teaching process, the following steps should be taken: firstly, the students should find a problem in their clinical practice; then, theyshould search for the evidence with the help of their teachers, evaluate the evidence, apply the evidence to the clinical practice, and solve the problem; finally, they should evaluate the effectiveness. An introduction of the principles and methods of EBM to the clinical practice can greatly improve the students’ ability to analyze and solve a clinical problem.
Objective To investigate the cognitive attitudes of evidence-based medicine (EBM) and barriers to applying EBM in clinical practice in medical postgraduates. Methods One thousand and one hundred and thirtyseven medical postgraduates selecting the EBM courses were surveyed by questionnaires.SPSS11.5 software was used for statistical analysis. Results Medical postgraduates acquired the knowledge of EBM through classroom and seminar. Medical postgraduates though that EBM could guide clinical research and improve operational lever and sever patient. More and more postgraduates will to take part in relevant training of EBM. The barriers to using EBM in clinical practice included lack of EBM knowledge, searching and accessing evidence, having influences from clinical experience and authorities, uncertainties about the effectiveness of evidence. Conclusions EBM education has transformed from dissemination and popularization stage to application stage. We should strengthen the training of clinical evidence-based practice.by evidence-based medical education.
