During long-term electrocardiogram (ECG) monitoring, various types of noise inevitably become mixed with the signal, potentially hindering doctors' ability to accurately assess and interpret patient data. Therefore, evaluating the quality of ECG signals before conducting analysis and diagnosis is crucial. This paper addresses the limitations of existing ECG signal quality assessment methods, particularly their insufficient focus on the 12-lead multi-scale correlation. We propose a novel ECG signal quality assessment method that integrates a convolutional neural network (CNN) with a squeeze and excitation residual network (SE-ResNet). This approach not only captures both local and global features of ECG time series but also emphasizes the spatial correlation among ECG signals. Testing on a public dataset demonstrated that our method achieved an accuracy of 99.5%, sensitivity of 98.5%, and specificity of 99.6%. Compared with other methods, our technique significantly enhances the accuracy of ECG signal quality assessment by leveraging inter-lead correlation information, which is expected to advance the development of intelligent ECG monitoring and diagnostic technology.
ObjectivesTo assess the methodological quality of Chinese clinical practice guidelines (CPGs) for diagnosis and management of atrial fibrillation, and to provide methodological advice for developing and updating CPGs for atrial fibrillation in future. MethodsCBM, CNKI, WanFang Data and VIP databases were electronically searched to collect filter relevant CPGs from inception to Feburary, 2018. Two reviewers independently screened literature, extracted data and evaluated the quality of eligible CPGs by using the appraisal of guidelines for research and evaluation (AGREE Ⅱ) instrument. ResultsA total of 10 CPGs were included. The standardized mean scores for AGREE Ⅱ were: 54.17% for scope and purpose, 18.89% for stakeholder involvement, 15.89% for rigor of development, 66.39% for clarity and presentation, 34.9% for applicability, and 0 for editorial independence. ConclusionsThe quality of Chinese CPGs for atrial fibrillation is low. More efforts should be made to enhance the quality of CPGs for atrial fibrillation using methodological rigorous frameworks and strengthen guideline reporting.
ObjectiveTo comprehensively collect quality assessment tools of systematic review/meta-analysis (SR/MA) of randomized controlled trials (RCTs), and compare the differences of numbers and contents of items, in order to provide references for optimizing and using these quality assessment tools. MethodsWe searched PubMed and EMbase databases up to December 31th, 2013 for quality assessment tools of SR/MA of RCTs. EndNote X3 software was used for screening literature and Excel 2010 software was used for data extraction. A descriptive analysis was performed. ResultsA total of 61 studies including 32 quality assessment tools were included. Among them, 30 tools were for methodological quality and 2 tools for reporting quality. These tools were developed by different medical universities or colleges, research institutes, national health institutes, and some famous epidemiologists and methodologists from 1984 to 2007. Among the 32 tools, 4 tools were scales, while 28 were checklists. The numbers of items of these tools ranged from 5 to 101, among them, 9 tools had more than 20 items. ConclusionThere are many quality assessment tools for SR/MA, but none of them is generally acknowledged. The quality, contents of items, and applicability of these tools are different, and some of them are too long to use. In practice and decision-making, most of the tools have the problems of low relevance and applicability. How to regularly use these tools to guide the research, practice and decision-making of SR/MA is still needed to be further researched.

This article reviews the historical development and current status of CPG evaluation tools, examining their diversity, complexity, application challenges, and inconsistencies in evaluation outcomes. A thorough discussion is provided on the strengths and weaknesses of existing evaluation tools, along with proposed future developmental directions. It is recommended that future efforts prioritize the creation of more streamlined tool designs, foster enhanced international collaboration strategies, and incorporate artificial intelligence technologies. These initiatives aim to improve both the efficiency and accuracy of evaluative processes while facilitating advancements in healthcare practices towards elevated quality standards.
ObjectivesTo investigate the current situation of clinical practice guidelines (CPGs) of gastric cancer in China, and to assess the quality of these CPGs, so as to provide reference for developing the CPGs of gastric cancer normatively in the future.MethodsCNKI, WanFang Data, CBM and VIP databases were electronically searched to collect the CPGs of gastric cancer in China from inception to January 31st, 2018. Four reviewers independently screened literature, extracted data and assessed the quality of these CPGs using the Appraisal of Guidelines for Research and Evaluation Ⅱ(AGREE Ⅱ).ResultsA total of 12 guidelines published from 2007 to 2017 were included. Only 1 guideline was evidence-based guideline. The average scores of guidelines in six domains of AGREE Ⅱ were 83.3%, 42.2%, 16.3%, 80.2%, 37.3% and 0% respectively.ConclusionsThe overall quality of included CPGs is insufficient. There is a lack of evidence-based guidelines in China. More attention should be paid to rigor of development and applicability during the development of CPGs in the future, and a timely upgrade is also required.
Objective To systematically review indicators and methods of quality assessment for primary health care, to provide empirical evidence for quality improvement in this area. Methods We electronically searched databases including Proquest Dissertations and Theses, ISI Web of Knowledge, PubMed, EMbase, IDEAS, Jstor, SSRN, Popline and The Cochrane Library (Issue 4, 2014) and network resources on World Bank, World Health Organization and Google from inception to April 2014. Empirical studies about quality assessment of primary care system, organization and personnel were collected. Data was extracted using pre-designed form for qualitative analysis and description. Results A total of 59 studies were included. The quality assessment for primary health care in practice was mainly from four dimensions: (1) emphasize on the implementation of such basic characteristics of primary health care as first contact, coordination, comprehensiveness and continuous; (2) focus on the evaluation of primary care contents, such as basic medical care, preventive care, chronic diseases, etc.; (3) based on the structure, process and outcome quality proposed by Donabedian; (4) emphasize on patients’ perceived quality. Seven relevant tools were widely used in the process of quality assessment in practice. Conclusion The majority of included studies were from developed countries while such empirical studies lacked in developing countries. Included studies varied in the connotation and angel of the primary health care quality, among which, the GPAS (General Practice Assessment Survey) used for evaluating pati ent perceived quality and PCAT (Primary Care Assessment Tools) used for evaluating the basic characteristics of primary care were widely used.
Objective To evaluate the methodological and reporting quality of clinical guidelines and consensus for adult AIDS. Methods Databases including PubMed, EMbase, Web of Science, CBM, WanFang Data and CNKI were electronically searched and major guideline websites such as GIN, NICE, NGC and Yimaitong were also searched to collect guidelines and consensus for adult AIDS from inception to December 2021. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. Four reviewers evaluated the methodological and reporting quality of the included guidelines and consensus by using AGREE Ⅱ and RIGHT, respectively. Results A total of 17 adult AIDS guidelines and consensus were included. The average scores of AGREE Ⅱ in various domains were 59.48% for scope and purpose, 37.17% for stakeholder involvement, 30.76% for rigor of development, 74.75% for clarity of presentation, 35.54% for applicability, and 50.49% for editorial independence. The items with the highest reporting rate among the RIGHT evaluation items were 1a, 1b and 1c (100.00%), followed by 3 and 4 (94.12%), 13a and 13b (88.24%), 7b and 11a (76.47%), and 5 (64.71%), and the remaining items were all reported below 60%. Results of subgroup analysis showed that the clarity of presentation, applicability and editorial independence of the guidelines for adult AIDS expressed in AGREE Ⅱ and the average score of RIGHT were higher than those of the consensuses for adult AIDS; the average scores of guidelines and consensuses based on evidence-based medicine in five domains of AGREE Ⅱ (scope and purpose, stakeholder involvement, rigor of development, clarity of presentation and applicability) and RIGHT were higher than those based on expert opinions or reviews. The foreign guidelines and consensus had higher average scores in the six domains of AGREE Ⅱ and the RIGHT score than the domestic guidelines. Conclusion The methodological quality and reporting quality of the published clinical guidelines and consensuses for adult AIDS is low; in particular, there is a certain gap between the national and international guidelines and consensuses. It is suggested that future guideline developers should refer to international standards, such as AGREE Ⅱ and RIGHT, formulate high-quality guidelines and promote their application to better regulate the diagnosis and treatment of adult AIDS.
