Objective To evaluate the quality of Chinese literatures on the methodology of D-dimer diagnostic test. Method We searched CNKI (1994 to 2006) and CBM (1978 to 2006) for articles involving the diagnostic tests of D-dimer for coagulation disorders. Result A total of 63 relevant articles were retrieved and 7 were included in our review. Only one of these provided useful data on two two table for the evaluation of diagnostic accuracy. Conclusions Few studies on the diagnostic tests of D-dimer have been performed and publ ished in China, all of poor quality. Further studies should focus on clinical diagnostic sensitivity and specificity, so as to provide more valuable information for readers.
Based on previous evidence-based researches and teaching experience, our team conducted literature and book review, and summarized 4 requirements, 1) effect measure calculation and conversion, 2) registration of evidence-based research, 3) evidence-based research database and 4) quality evaluation tools and reporting guidelines. We developed an online platform of evidence-based medicine research helper using the front-end and back-end technology, which can be accessed using www.ebm-helper.cn. Currently, the online tool has included 46 scenarios for effect measure calculation and conversion, introduction of 7 evidence-based research registration platforms, 26 commonly used databases for evidence-based research and 29 quality evaluation tools and reporting guidelines. This online tool can help researchers to solve specific problems encountered in different stages of evidence-based medicine research. Promoting the application of this platform in evidence-based medicine will help researchers to use the tool scientifically and improve research efficiency.
Objective To evaluate the current situation of the design of the randomized controlled trials (RCTs) in Clinical Anesthesiology, Chinese Journal of Anesthesiology and Chinese Journal of Pain Medicine from 1999 to September in 2003. Method The clinical therapeutic studies in the three journals from 1999 to September of 2003 were hand searched over page by page to identify strictly the randomized controlled trials according to Chinese Cochrane Center hand search guideline. Results 412, 378 and 142 papers of the three journals were published, among which, there were 237, 221 and 68 papers of RCT. Conclusions Although the quality of RCT in the three journals has been increased significantly year by year, but there still exist some problems. The quality of RCT papers needs more improvement to guarantee RCT to be more precise as it demands.
Objective To investigate patients in gynecological endocrinology clinic with the following three pieces of information: how did they provide their symptom information, how did they understand diagnostic and therapeutic information, and what was their attitude towards the visit, and to get to know about the situation and problems in doctor-patient communication, so as to aim directly at improving the efficiency of diagnosis and treatment. Methods A total of 403 patients, who visited Prof. HAN Zi-yan’s clinic in the hospital from April to August 2010, were evaluated using self-edited Assessment on Doctor-patient Communication in Gynecological Endocrinology Outpatient Clinic. Results a) As to the situation of patients providing symptom information as well as understanding diagnostic and therapeutic information, when doctor asked, only 29% (118/403) of patients could narrate their treatment history clearly, and 38% (152/403) could tell their examination history exactly. After doctors’ explanation, only 21% (86/403) understood their examination results correctly, and 27% (108/403) understood management and therapeutic advice. The result of correlation analysis showed the accuracy of patients in providing disease information and accepting diagnostic and therapeutic information was higher in patients aged from 21 to 40 rather than those younger than 20, in patients well- educated rather than those with little education at the primary school, and in patients who were also engaged in medical work, All differences were significant (all Plt;0.05); and b) As to patients’ attitude towards visit, 55% (222/403) of patients hoped to get more attention from doctor, and 37.5% (151/403) overly expected the visit. Conclusion In the professor’s gynecological endocrinology outpatient clinic, many patients can’t clearly provide their treatment and examination history, neither understand exam situation and therapeutic advice at that visit, which are influenced by their age, education and occupation. In addition, psychological needs of patients should be concerned, too
ObjectiveTo evaluate the quality of randomized controlled trials (RCTs) of Chinese medicine (TCM) formulated granules published in core journals in China. MethodsComputerized searches were conducted in CNKI, VIP, WanFang Data and CBM databases. The publicly published RCTs of TCM formulated granules were collected, with sources from Peking University Core, CSSCI and EI. The following information was extracted: including title, the first author, the journals name, type of disease, year of publication, and source of drug. The included studies were evaluated using the CONSORT extension for CHM formulas (CONSORT-CHM formulas 2017), which included 25 items from title, abstract and keywords, introduction, research methods, steps, results, discussion, and other information. ResultsA total of 125 papers were included, which mainly included digestive system diseases (n=25), respiratory system diseases (n=17), and circulatory system diseases (n=17). The results showed that the overall reporting quality of RCTs of TCM formulated granules was poor. After the publication of the CONSORT-CHM formulas 2017, the reporting quality of RCTs of TCM formulated granules had no significant changes, while some items were still reported with poor quality. For example, 42.2% of RCTs did not adequately report how to generate allocation sequence, 93.3% of RCTs did not adequately report allocation concealment, and 62.2% of RCTs did not adequately report how to solve the missing data. ConclusionThe quality of RCTs reports on TCM formula granules published in Chinese journals still needs to be improved. It is recommended that researchers, journals and reviewers attach importance to the application of CONSORT-CHM formula throughout the whole process of paper writing. In the future, more scientific and detailed requirements should be put forward for trial design and reporting standards in line with the characteristics of clinical trials of TCM formula granules.
Objective To evaluate the methodological and reporting qualities of randomize controlled trials involving MTC (microwave tissue coagulation) therapy for cervical erosion. Methods Through computer and handsearch, randomized controlled trials (RCTs) and/or quasi-randomized controlled trials (quasi-RCTs) were collected. The methodological quality of the included studies was assessed using quality assessment criteria of Cochrane systematic review guideline, and the reporting quality was assessed using the CONSORT (Consolidated Standards of Reporting Trials) checklist.Results Eleven clinical controlled trials (CCTs) were included. Three were RCTs and eight were quasi-RCTs. The methodological and reporting qualitiy of the included studies was generally low (10 trials ranked Level C, and the maximum CONSORT score was only 17).Conclusions The quality of the CCTs involving microwave therapy for cervical erosion is generally low with a high risk of biases. And the reporting of these trials is also incomplete. Therefore, more randomized controlled trials of high quality are required to provide reliable evidence.
Objective To evaluate the quality of undergraduate medical education so as to provide useful and effective feedback information for medical schools and to extend GMER (Global Minimum Essential Requirements in Medical Education) standard. Methods Through questionnaires, 205 resident doctors self-evaluated their abilities or qualities based on GMER standard. The unconditioned logistic regression model was used for data analysis. Results Graduates from undergraduate medical programs mastered the abilities or qualities required in 4 GMER domains i.e. “professional values, attitudes, behaviors and ethics”, “clinical skills”, “communication skills”, and “scientific foundation of medicine”. But the abilities or qualities required in “information management”, “population health and health systems” as well as “critical thinking and research” domains have not been obtained. The main factors that affected the evaluation results were corresponding training to the essentials, learner’s attitude, teaching models and teaching hours. Conclusion Educational sectors should adjust curriculum design so as to help medical students master the abilities required in the 3 domains stated above. Medical schools should conduct some educational research to formulate the most beneficial teaching methods, and import advanced ones to raise the quality of medical education in China.
Large Language Models (LLMs) are highly sophisticated deep learning models pre-trained on massive datasets, with ChatGPT representing a prominent application of LLMs in the field of generative models. Since the release of ChatGPT at the end of 2022, generative chatbots have become widely employed across various medical disciplines. As a crucial discipline guiding clinical practices, the usage of generative chatbots like ChatGPT in Evidence-Based Medicine (EBM) is gradually increasing. However, the potential, challenges, and intricacies of their application in the domain of EBM remain unclear. This paper aims to explore and discuss the prospects, challenges, and considerations associated with the application of ChatGPT in the field of EBM through a review of relevant literature. The discussion spans four aspects: evidence generation, synthesis, assessment, dissemination, and implementation, providing researchers with insights into the latest developments and future research suggestions.
National Center for Medical Service Administration of National Health and Family Planning Commission of China was established at the beginning of 2015. It is mainly in charge of developing and managing standards of medical technology and organizing their implementation, and giving technical guidance and consulting for evaluation of medical institutions. The foundation of the center fills in the blank of lacking central administrative department of the guideline development and evaluation. This paper introduces the definition and the function of clinical practice guideline, and analyzes the current situation, problems and challenges of domestic guidelines, and proposes some potential suggestions on improving the quality of Chinese guidelines from national level for promoting the standardization, scientification and transparency of clinical practice guidelines in China.
ObjectiveTo evaluate the quality of protocols and reports on the core outcome set of traditional Chinese medicine (COS-TCM), and to provide some evidence for COS-TCM developers to carry out studies and improve the reporting quality and methodological quality during their studies. MethodsLiterature databases in Chinese and English were searched to collect COS-TCM protocols or study reports from inception to April 18, 2023. The Core Outcome Set-STAndards for Reporting (COS-STAR), Core Outcome Set-STAndards for Development (COS-STAD), and Core Outcome Set-STAndardised Protocol Items (COS-STAP) were used to evaluate their reporting and methodological quality. Additionally, the consistency of studies with both published protocols and results was evaluated. ResultsA total of 14 protocols and 14 reports (involving 23 COS-TCM studies) were included. The evaluation of COS-TCM protocols according to the COS-STAP found that the reporting rates of "Stakeholders" (71.4%) and "Missing data" (42.9%) were relatively low. For the reports of COS-TCM, the evaluation based on the COS-STAD found that the reporting rates of "the population (s) covered by the COS" (35.7%) and "care was taken to avoid ambiguity of language used in the list of outcomes" (28.6%) were relatively low. Based on the COS-STAR, the items with low reporting rates were "Protocol Deviation" (7.1%), "Participants" (21.4%), and "Conflicts of interest" (28.6%). Additionally, the consistency evaluation found that there were inconsistencies between protocols and their results, such as the types of research included in the systematic review, the methods of qualitative research, the way of holding consensus meetings, scoring methods, etc. Moreover, only one study reported protocol deviation and reasons for change. ConclusionCOS-TCM studies need to improve their methodological quality and report transparency. When developing COS-TCM, we should pay attention to the characteristics of TCM while basing on international standards. The quality evaluation guidelines and standards of reporting for COS-TCM study need to be developed in the future.
