The aim of this paper was to evaluate reporting and methodological quality of systematic reviews or meta‐analyses in the nursing field in China. Over the last decade, evidence‐based nursing has been gradually known and accepted by nurses in China, and the number of systematic reviews or meta‐analyses of nursing flied has steadily increased, but the quality of these reviews is unsatisfactory. The Chinese Journal Full‐Text Database, the Chinese Biomedicine Literature Database and the Wanfang Database were searched for systematic reviews or meta‐analyses in the nursing field, from inception through December 2011. The Preferred Reporting Items of Systematic Reviews and Meta‐analyses and the Assessment of Multiple Systematic Reviews checklists were used to assess reporting characteristics and methodological quality, respectively. A total of 63 systematic reviews or meta‐analyses were identified. The deficiencies of methodological quality were mainly in literature searches, heterogeneity handling, recognition and assessment of publication bias. In addition, the deficiencies of reporting characteristics were reflected in incomplete reporting of literature search, quality assessment, risk of bias and results. Focusing on improving the quality of reporting and methodological quality of systematic reviews or meta‐analyses in the nursing field in China is urgently needed.  相似文献

To evaluate the epidemiological characteristics, reporting characteristics, and methodological quality of systematic reviews in the traditional Chinese medicine nursing field published in Chinese journals. The number of systematic reviews in the traditional Chinese medicine nursing field has increased, but their epidemiology, quality, and reporting characteristics have not been assessed completely. We generated an overview of reviews using a narrative approach. Four Chinese databases were searched for systematic reviews from inception to December 2015. The Preferred Reporting Items of Systematic Reviews and Meta‐analyses and the Assessment of Multiple Systematic Reviews checklists were adopted to evaluate reporting and methodological quality, respectively. A total of 73 eligible systematic reviews, published from 2005 to 2015, were included. The deficiencies in reporting characteristics mainly lay in the lack of structured abstract or protocol, incomplete reporting of search strategies, study selection, and risk of bias. The deficiencies in methodological quality were reflected in the lack of a priori design and conflict of interest, incomplete literature searches, and assessment of publication bias. The quality of the evaluated reviews was unsatisfactory; attention should be paid to the improvement of reporting and methodological quality in the conduct of systematic reviews.  相似文献

The importance of systematic reviews (SRs) of nursing interventions' impact on practice makes their methodological quality and reporting characteristics especially important as it directly influence their utility for clinicians, patients and policy makers.The study aims to assess the methodological quality and reporting characteristics of SRs of nursing interventions in Chinese nursing journals. Three Chinese databases were searched for SRs of nursing interventions from inception to October 2011. The assessment of multiple systematic reviews (AMSTAR) and Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) statements were used to assess methodological quality and reporting characteristics. Seventy‐four SRs were included. The proportion of SRs complying with AMSTAR checklist items ranged from 0% to 82.4%. No SRs reported an ‘a priori’ design or conflict of interest. Only four items were found to be reported in more than 50% of the SRs: a list of included and excluded studies, the scientific quality of included studies, the appropriate use of methods to combine findings, and formulating conclusions appropriately. The majority of SRs of nursing interventions in China had major methodological and reporting flaws that limited their value to guide decisions. Chinese authors and journals should adopt and keep up with the AMSTAR and PRISMA statements to improve the quality of SRs in this field.  相似文献

Abstract Background: Systematic reviews (SRs) of acupuncture have become increasingly popular in China in recent years and have been published in large numbers. This review provides the first examination of epidemiological characteristics of these SRs as well as compliance with the PRISMA and AMSTAR guidelines. Objectives: The study objectives were to examine epidemiological and reporting characteristics as well as methodological quality of SRs of acupuncture published in Chinese journals. Methods: Four (4) Chinese databases were searched (CBM, CSJD, CJFD, and Wanfang Database) for SRs of Traditional Chinese Medicine, from January 1978 through to December 2010. Data were extracted into Excel spreadsheets. The PRISMA and AMSTAR checklists were used to assess reporting characteristics and methodological quality, respectively. Results: A total of 88 SRs were identified; none of the reviews had been updated. Less than one third (27.3%) were written by clinicians and one third (35.2%) were reported in specialty journals. The impact factor of 53.4% of the journals published was 0. Information retrieval was not comprehensive in more than half (59.1%) of the reviews. Less than half (36.4%) reported assessing for publication bias. Though 97.7% of the reviews used the term "systematic review" or "meta-analysis" in the title, no reviews reported a protocol and none were updated even after they had been published after 2 or more years. Conclusions: Although many SRs of acupuncture interventions have been published in Chinese journals, the reporting quality is troubling. Thus, the most urgent strategy is to focus on increasing the standard of SRs of acupuncture interventions, rather than continuing to publish them in great quantity.  相似文献

BackgroundThe Buyang Huanwu Decoction (BYHWD) originated from Wang Qingren’s “Yi Lin Gai Cuo”. It has the effect of tonifying qi and activating blood circulation and dredging collaterals which is recommended for the treatment of Ischemic stroke in China. In recent years, there have been many systematic reviews of Ischemic stroke treated by BYHWD assessing the efficacy of BYHWD in the treatment of Ischemic stroke in the acute, convalescent and sequelae stages. Because of the different methods of analysis, the quality and quality of the evidence obtained in these systematic reviews is different, so a systematic re-evaluation was needed to comprehensively evaluate the strength of these studies.MethodsSystematic reviews and meta-analyses of Ischemic stroke treated by BYHWD were identified through the Web of Science, PubMed, CNKI, Weipu, and Wanfang databases. The included studies were selected for literature screening, methodological quality evaluation, and evidence level evaluation by two investigators. The methodological quality was evaluated by the 2020 PRISMA guidelines, Assessing the Methodological Quality of Systematic Reviews (AMSTAR) scale, and the evidence quality was evaluated by the GRADE criteria.ResultsOverall, 12 studies involving 28,594 patients between 2006–2021 were included in this analysis. The methodological quality evaluation based on 2020 PRISMA guidelines results showed that there were many weaknesses in registration and protocol, support, competing interests, competing interests and availability of data, code and other materials. The AMSTAR scale evaluation results showed that the 12 studies were very low quality. The results of the GRADE criteria evaluation showed that the quality of the evidence was scattered, with mainly low-quality evidence.ConclusionThe methodological quality of systematic reviews and meta-analyses of BYHWD in treating Ischemic stroke was generally poor, and the quality of evidence was generally low.  相似文献

CONTEXT: Good systematic reviews/meta-analyses are important sources of information for clinicians, patients, government officials, and other decision makers. Now, there is an increasing number of systematic reviews/meta-analysis of Traditional Chinese Medicine (TCM). Thus, it is necessary to assess the quality of these reviews. OBJECTIVE: To assess the methodology and reporting quality of systematic reviews/meta-analyses of TCM published in paper-based journals in China. METHODS: A comprehensive search of the literature was performed to identify the maximum possible number of reviews on the prevention and cure researches in TCM. Two assessors (Junhua and Hongcai) independently extracted data and put them into a Microsoft Access database for analysis. Two assessment tools were used: (1) the Oxman-Guyatt Overview Quality Assessment Questionnaire (OQAQ); and (2) the Quality of Reporting of Meta analysis (QUOROM). RESULTS: One hundred and seven papers (107) were identified: 71 reviews called "systematic reviews" and 36 called "meta-analyses." More than half of all the reviews had methodological and reporting flaws that could have influenced the reviews' validity. The deficiencies were mainly in literature searches, characteristics of included and excluded studies reported, primary trials' quality assessment, and data merging. CONCLUSIONS: The methodology and reporting quality are poor in both systematic reviews and meta-analysis reviews of TCM published in paper-based journals in China. We should respect the need for high-quality of systematic reviews and meta-analyses, and do these according to specification.  相似文献
