Objective To observing about how effect is the education prescription using by the medical students, looking into whether the manner can attach the students attention and improve on the retrieval ability for them. Methods Choosing one of the cases come from PubMed and drawing out a clinical question. Asking total 100 students to search literature and write search strategy, search results and the reason about the results by chosen (similar to appraisal evidence), and their self-evaluation of this process. Results Of the 100 students, 96 (96%) searched PubMed/MEDLINE, and 79 (79%) searched second research database, 28 (28%) searched Science Citation Index (Web of Science), 38 (38%) chosen one of ten articles according with the articles chosen by the overseas doctors. We found no students weren’t interesting in the education prescription, but 65 (65%) didn’t think the education prescription be easy achieved, at the same time they mentioned that the retrieval problems were solved or profited came from the practice. Conclusions Filling education prescription can attract students attention and induct them to learn the basic concept of EBM, and to practice how to searching evidence and the feedback of students can help improve on teaching work.
With the rapid development of evidence-based medicine during the past two decades, evidence andevidence-based methods were not only used in the field of health care, but also applied to other non-medical fields. Asystematic literature search and a comparative study were conducted to investigate the definition of evidence. We also putforward our own definition of evidence: Evidence is the information from the systematic review process. We also discussedthe development of evidence-based paradigm and hope this will act as a reference for other subjects and industries.
Gout is caused by abnormal metabolism of purine. Its most common symptom attack of intense pain and swelling in the joints. Attacks of gout can according to the alteration if it is in acute interval periods. How can we get the optimal effect? The development of methodology has provided much convincing evidence for us to choose the most appropriate treatment.
Objective To explore the characteristics of articles related to Evidence-based Nursing (EBN) and to identify the problems and difficulties encountered by clinical nurses when they were engaged in evidence-based practice in China.Methods We searched for articles published in 6 nursing journals in China from 2000 to early 2006, and classified, investigated and analyzed the retrieved articles. Results Research on EBN has been changing from explaining theories and methods to applying research results in nursing practice. Among articles on clinical application, 90.9% did not describe the methods and search strategy used; 63.6% did not specify the sources of the evidence applied in practice; 93.9% did not describe the methodological quality of the evidence; only 6.1% used the results of systematic reviews or randomized trials to guide clinical practice; and 72.7% did not use effective evaluation methods to identify the nursing outcomes after applying evidences in clinical practice. Conclusions The quality of EBN related articles needs to improve further. Nurses should learn more about the knowledge and skills associated with EBN so as to improve the quality of nursing practice and of academic articles on EBN
The steps of searching evidence were introduced. How to select computer retrieval systems and searching engines were discussed including evidence retrieval systems and other medical information retrieval systems, bibliography systems and full-text systems, metasearch engine systems and single search engine systems, as well as the engines for evaluating information and the general medical search engines.
Objective To evaluate and select essential medicine for chronic obstructive pulmonary diseases (COPD) using evidence-based methods based on the burden of disease. Methods By means of the approaches, criteria, and workflow set up in the second article of this series, we referred to the recommendations of evidence-based or authority guidelines from inside and outside China, collected relevant evidence from domestic clinical studies, and recommended essential medicine based on evidence-based evaluation. Data were analyzed by Review Manager (RevMan) 5.1 and GRADE profiler 3.6 to evaluate quality of evidence. Results (1) Nine guidelines were included (eight foreign guidelines, one domestic guideline; seven based on evidence, two based on expert consensus). (2) A result of one domestic RCT (n=72, high quality) indicated that tiotropium could significantly improve pulmonary function of severe COPD patient complicated with respiratory failure and increase their quality of life (SGRQ score: MD=–10.8%, 95%CI –12.2% to –9.4%). A result of one RCT (n=156, moderate quality) with 3-month follow-up indicated that tiotropium could significantly improve the proportion of measured value to expected value of FEV1 in patients with mild and moderate COPD in stationary phase (MD=10.3%, 95%CI 8.1% to 12.5%). A result of two RCTs (n=160, low quality) indicated that compound ipratropium bromide had efficiencies of 84.2% to 87.5% for moderate and severe COPD. A result of one RCT (n=60, moderate quality) indicated that salmeterol/fluticasone (inhalation) was superior to placebo for improving mild and moderate COPD in stationary phase. A result of one RCT (n=725, moderate quality) indicated that tiotropium combined with salmeterol/fluticasone for COPD in stationary phase was superior to tiotropium alone. A result of one RCT (n=110, low quality) indicated that nebulized budesonide inhalation had an efficiency of 86.8% for acute exacerbation of COPD (AECOPD) and an incidence of 7.9% as to adverse reaction that mainly included laryngo-pharyngeal irritation. (3) Imipenem, meropenem, cefoperazone/ sulbactam and ceftazidime were effective for COPD with low drug resistance rates in treating COPD caused by non-ICU pathogens (less than 8%). Conclusion (1) We offer a b recommendation for tiotropium, ipratropium, salbutamol, formoterol, salmeterol and theophylline used in the treatment of COPD in stationary and exacerbation phases, a b recommendation for streptococcus pneumoniae and influenza vaccines in preventing the deterioration of COPD, a b recommendation for inhaled corticosteroids (ICS) used in the treatment of COPD in stationary phase and a b recommendation for corticosteroids (for oral use) for AECOPD. (2) We offer a b recommendation for cefoperazone/sulbactam, imipenem and meropenem used in the treatment of moderate and severe AECOPD. (3) We offer a weak recommendation for ceftazidime, ciprofloxacin, lavofloxacin, moxifloxacin, amoxicillin amp; clavulanate potassium, amoxicillin, azithromycin, clarithromycin and doxycycline as first-line and second-line antibiotics for mild and moderate AECOPD, and a weak recommendation for compound sulfamethoxazole, cefatriaxone, cefotaxime and cefuroxime used in the treatment of severe and extremely severe COPD, mucolytic agents used in the treatment of stable COPD with difficult expectoration. (4) We make a recommendation against antibiotics, expectorants and corticosteroids (for oral use) as routine use in stationary phase of COPD.
