Objective To investigate the health technology assessment reports, analyze publication characteristics and report quality, and explore hot topics in health technology assessment. Methods Web of Science and CNKI databases were searched to collect complete health technology assessment reports from inception to January 2023. SPSS 26.0 software was used to analyze the publication journals, countries, number of authors, assessment types and assessment contents of the assessment reports. The report quality was assessed based on International Network of Agencies for Health Technology Assessment (INAHTA) report criteria (2007 edition). VOSviewer 1.6.11 was used to analyze keywords clustering. Results A total of 216 papers were included, with 158 published by Chinese authors, and a rapid growth trend in the number of reports over past four years. The rate of reports on health technology social adaptability assessment was only 17.13%. Among the Chinese reports, 25 were general health technology assessments, 35 were rapid assessments, and 3 were mini assessments. Among the English reports, 4 were rapid assessments, and 54 were regular healthcare technology assessments. For the 14 items in the INAHTA reporting criteria, the reporting rates were high for the brief summary (98.61%), problem description (94.91%), and results discussion entries (97.69%). However, the reporting rates were low for criteria such as personnel responsibilities, conflict of interest statements, and peer review statements, at 31.94%, 19.44%, and 3.24% respectively. English literature generally exhibited higher report quality. Conclusion In recent years, the volume of health technology assessment reports in China has been increasing, with developments in assessment types and application fields. However, there are also problems with standardization of reporting.
Rapid development is undergoing in the field of rehabilitation robots, and more countries (regions) are participating in international cooperation and becoming academic contributors. Here in this study, the bibliometric method is used to determine the dynamics and developments of international cooperation in China. The publication data are indexed in Web of Science with search term of rehabilitation robot from 2000 to 2019. Compared with other countries (regions), publication with international co-authors and institutes participating in international cooperation are studied by assessment of indicators such as the cooperation degree, cooperation frequency, and the frequency of citations. The results show that in the past two decades, international scientific cooperation has shown a positive tendency in China, and participating in international collaboration could improve China’s impact on the global rehabilitation robot. The United States, England and Japan are the top three countries in number of cooperation with China. Our findings provide valuable information for researchers to better understand China’s international scientific collaboration in rehabilitation robot.

Objective To analyze the research status of immunonutrition in China based on Chinese databases, and to provide a reference for clinical practice and future research. Methods Literatures about the application of immunonutrition in nutrition support were searched in China National Knowledge Infrastructure, SinoMed, Chongqing VIP and Wanfang databases using bibliometrics methods. The retrieval time was up to August 2022, and the document characteristics such as the number of publications, the institutions and the citation frequency and other features were analyzed. Results A total of 725 literatures were included, with the highest number of literatures issued in 2015 and 2020, both 62. The areas with the most published literatures were Jiangsu (10.6%) and Guangdong (8.4%). The institutions with the most published literatures were General Hospital of Eastern Theater Command (4.8%) and West China Hospital of Sichuan University (3.9%). There were 78 dissertations and 647 journal articles in total. The most published journal was Parenteral & Enteral Nutrition (6.5%). The top three citations were all reviews. The degree of cooperation was 2.7, and the co-authorship rate was 70.1%. A total of 121 articles reported the supporting funds and projects. The research types included 499 original studies (68.8%) and 226 secondary studies (31.2%). The analysis of the subjects showed that immunonutrition was mostly applied to gastrointestinal diseases, especially gastrointestinal cancer patients, accounting for 42.5%. Nutritional support was divided into enteral nutrition and parenteral nutrition. Enteral nutrition was adopted in most literatures, accounting for 88.4%. Conclusions The research content of immunonutrition in Chinese database in China is relatively simple. Most of them focus on the comparison between immunonutrition and general nutrition support. The selection of immune nutrients and the application of immunonutrition in critically ill patients such as sepsis need further research.
Objective To explore the global research status and trends of continuous renal replacement therapy (CRRT) based on knowledge visualization analysis. Methods Based on the Web of Science Core Collection, studies reporting CRRT research that were published between June 2014 and June 2023 were retrieved and collected after manual review. VOSviewer and CiteSpace softwares were used for bibliometric visualization analysis, including publication trends, geographical distribution characteristics, journal distribution characteristics, author contributions, citations, funding source characteristics, and keyword clustering. Results A total of 2708 papers were analyzed, with an increasing trend in the number of articles and citation frequency from 2015 to 2021. The United States was the most prolific country and France was the most influential country. The University of Pittsburgh in the United States had the highest number of publications among research institutions and showed higher motivation for inter-institutional collaboration. The University of Queensland in the Australia had the highest average citation frequency. Professor Rinaldo Bellomo of Australia was the most productive author and Professor Jeffrey Lipman was the most influential. Jason A. Roberts, Jeffrey Lipman and Claudio Ronco were the three authors who had the highest number of collaborations with other authors. Keyword cluster analysis showed that the prognosis of CRRT for renal disease was the focus of research, with hotspots of research being antibiotics, citrate accumulation, plasma replacement, lactate clearance, acute respiratory distress syndrome, and coronavirus disease 2019. Coupling analysis of the literature showed that exploring the indications for CRRT and optimizing treatment prescription were at the forefront of research. Conclusions The present study of CRRT has generally shown an upward trend in the last decade. The management and efficacy of CRRT remains a hot topic of research. Exploring the indications for CRRT and optimizing treatment prescriptions may be a popular research direction and trend in the future.
ObjectiveTo investigate the hotspots from researches on imaging of pancreatic neuroendocrine tumor in recent five years. MethodsThe bibliographies from research literatures on imaging of pancreatic neuroendocrine tumor from 2010 to 2015 in PubMed database were downloaded. The Bicomb 2.0 bibliographies analysis software was used to count high-frequency of Mesh major topics (MJMEs). SPSS 22.0 statistical software was applied for clustering analysis with MJMEs, then to get the topic hotspots. ResultsA total of 357 literatures were screened out during the years of 2010-2015. The MJMEs which frequency > 13 were 28. Taken the 28 MJMEs into clustering analysis, then three research hotspots were clustered. ConclusionResearches on imaging of the pancreatic neuroendocrine tumor in recent five years are mainly in terms of imaging techniques, a comparative study of pathology and endoscopic ultrasonography-fine needle aspiration, imaging and disease treatment.
为了解我国南方地区肺栓塞的现状,通过检索中国医院数字图书馆近9年(1999年～2008年)南方地区正式发表的与肺栓塞和深静脉血栓有关的论文共1288篇,进行了统计分析,发现:1、中国南方地区肺栓塞的发现数量逐年增加,且增幅明显;2、诊断水准达到一定程度的部分南方医院,诊断治疗肺栓塞的数量明显高于其他医院,并不比中国北方同类医院低;3、肺栓塞的漏诊、误诊现象依然普遍存在,提高认知和诊治水准仍然是今后工作的方向。
