As a new discipline, the cardiac surgery has a great development in the modern age, but still faces many problems and disputes. The emergence of the evidence-based medicine(EBM),which emphasizes the best evidence, and combines the doctor’s clinical experience to make the best judgment, gives the development of the cardiac surgery a new thinking . Four systematic reviews published in The Cochrane Library (Issue 3, 2004) have interprated the importance of EBM on how to resolve the actual problems in different field of the cardiac surgery.
We summarized and analyzed the researches of the workshop on Evidence-Based Medicine for Medical Editors which was recently held concerning its teachers, training method, trainee distribution and recent progress. We hope to provide a new approach to improving the level of medical editors and clinical trials.
Objective To investigate baseline data of the current status of patients in China, and thus to develop strategies to get patients involved in evidence-based medicine (EBM). Method 300 questionnaires with 17 questions were distributed to the in-patients in West China Hospital, Sichuan University. Statistical software such as SPASS 10. 0 was applied to analyze all the data. Results No patients had ever heard of EBM. Most patients did not know much information about their diseases, but had a b desire to learn from their doctors. Most of them would like to be involved in the treatment decision-making and hoped that their doctors would care about their preference. The cost and the effectiveness of the treatment were the most important issues that patient concerned about. Conclusions The dissemination of health information is very limited for patients and the accessibility of effective health information depends much on the direct communication with their doctors. Promoting patient involved in EBM is fairly a hard and long way to go based on the actual reality of the country.
Objective To establish the Chinese Evidence-Based Medicine/Cochrane Centre Database of Clinical Trials and Diagnostic Tests to provide reliable scientific data for clinical practice, teaching, research and systematic reviewers and submit the results of randomised controlled trials (RCTs) and controlled clinical trials (CCTs) to The Cochrane Collaboration. Methods Data were collected by handsearching and electronic searching based on the criterion of the Collaboration and clinical epidemiology. Results Up to December 2003, there were 16 652 RCTs /CCTs and 3 786 DT included in the database. A total of 4 966 RCTs and CCTs were submitted to the Collaboration. Nineteen specialized databases were set up. Conclusions The first phase of the Chinese Evidence-Based Medicine/Cochrane Centre Database of Clinical Trials and Diagnostic Tests has been completed. The database has provided advice for contributiors both at home and abroad.
ObjectiveTo investigate the effect of evidence-based nursing course in undergraduate nursing students' critical thinking ability. MethodsA prospective cohort study design was performed in students from two nursing undergraduate classes, who elected evidence-based nursing course as an observation group and students lacked of the course as a control group. The Chinese Version of Critical Thinking Disposition Inventory (CTDI-CV) was used to test critical thinking ability at the beginning and the end of the semester. The scores of CTDI-CV and rank of scores were compared between the two groups using t test and rank sum test. ResultsA total of 88 students were included, of which 41 students were in the observation group and 47 students were in the control group. Compared to the control group, the observation group demonstrated significantly more improvement in the total scores (MD=22.29, 95%CI 13.477 to 31.114), the search for truth (MD=2.81, 95%CI 0.211 to 5.410), open-minded (MD=3.37, 95%CI 1.280 to 5.471), analysis capabilities (MD=3.41, 95%CI 1.351 to 5.481), systematicity (MD=3.39, 95%CI 1.447 to 5.336), confidence critical thinking (MD=2.83, 95%CI 0.512 to 5.152), curiosity (MD=4.53, 95%CI 2.273 to 6.786) and cognitive maturity (MD=1.93, 95%CI -0.502 to 4.377). The level of total scores, the search for truth, analysis capabilities, systematicty, confidence critical thinking, and curiosity in the observation group were significantly improved. ConclusionEvidence-based nursing course learning can improve the undergraduate nursing students' critical thinking skill.
Objective Evidence-based medicine was used to make an individualized treatment plan for newly diagnosed prostatic hyperplasia in an elderly patient. Methods After clinical problems were discovered, evidence was collected from CBM, CNKI, The Cochrane Library, PubMed, EMBASE, ScienceDirect, Springer, and ProQuest databases according to our predefined search strategy. The search was done through 2008. The internal and external validity of the evidence was assessed. The evidence, combined with the patient value, was applied to the patient. Results A total of 39 systematic reviews involving 137 randomized controlled trials were identified. A rational treatment plan was made upon a critical evaluation of the data. After one year follow-up, the treatment protocol was proven correct. Conclusion The treatment efficacy in newly diagnosed prostatic hyperplasia in the elderly has been improved by determining an individualized treatment protocol according to evidence-based methods.
Objective To formulate an evidence-based treatment plan for a child patient with Asymptomatic Wolff-Parkinson-White (WPW) Syndrome. Methods Based on the clinical problems whether the patients with asymptomatic WPW syndrome need prevent catheter ablation or not, we used “asymptomatic WPW syndrome” as the keywords and searched The Cochrane Library (Issue 3, 2007), MEDLINE (1981 to 2007), ACP Journal Club (1991 to 2007), BMJ Clinical Evidence (1999 to 2007) and NGC (1998 to 2007) for systematic reviews, randomized controlled trials (RCTs), controlled clinical trials and treatment guidelines. The methodological quality of the included studies was assessed to identify the current best evidence. Results Two RCTs were retrieved in MEDLINE. The results showed arrhythmic events increased significantly in the high-risk control group than those in the ablation group, and in the patients with multi-pathways than those with only one pathway. Based on the current evidence, integrated with clinical expertise and the patients’ values, the patients underwent electrophysiologic test and the result showed the dominance pathway in the right side and the concealed accessory pathway in the left side. Then prevent catheter ablation was performed, and no cardiovascular complications occurred in the following 12 months, which confirmed that the plan was proved optimal. Conclusion The findings of this study should reassure physicians and parents alike that in the children with the WPW syndrome who are at high risk for arrhythmias, ablation is an appropriate option.
Onehealth, an evidence-based decision-making software, is based on the United Nations' epidemiological reference modules to predict the effect of health services. Onehealth is a large database. The software is using activitybased costing, simulating investment costs of health system and changes of mortality in different coverage levels. By the cost of inputs/avoid deaths, it could quantify the cost of health services effectiveness and provide an intuitive basis for the rational allocation of health resources. This study introduces the relevant concepts, model structures and applications of Onehealth. We took the study of child nutrition interventions in Sudan for example and to present Onehealth tool's operating. As a new auxiliary and evidence-based decision-making software with scientific and rigorous theoretical approach, Onehealth has practical significance on the national or regional macro decision-making.
