Objective To review the literature written in English on hospital performance research and provide theoretical and practical references for research in the field of hospital performance in China. Methods Literature related to hospital performance published from 1972 to 2022 in the Web of Science Core Collection was retrieved. Microsoft Excel 2021 was used to analyze the annual publication volume of English literature in the field of hospital performance. CiteSpace 6.1.R6 software was used for co-occurrence analysis of countries/regions, institutions and authors, research hotspots and frontiers. Results A total of 1447 articles were ultimately included. The analysis of annual publication volume showed that the overall publication volume in the field of hospital performance was on the rise. The co-occurrence analysis of countries/regions indicated that the United States had the highest output of academic papers (548), followed by the United Kingdom and China (120 and 89 respectively). The most productive institution was Harvard University in the United States, and the most productive scholar was Harlan M. Krumholz from the Yale University School of Medicine in the United States. The most frequently occurring keyword was “care”. The clustering analysis of keywords revealed that the keywords in the field of hospital performance research were clustered into 12 categories. The top 5 keywords with the highest burst intensity included “acute myocardial infarction” “indicator” “US hospital” “predictor” and “administrative data”. Keywords such as “public hospital” “financial performance” “performance measurement” “framework” and “organizational performance” began to emerge in 2020 and had continued to the present. Conclusions The research hotspot in the field of hospital performance has shifted from focusing on individual performance to organizational performance. There is still a lot of room for research in this field in China, and the exploration of hospital performance evaluation and management models may continue to be research hotspots in this field in the future.
Objective To explore the research trends of traditional Chinese exercise in the rehabilitation of chronic obstructive pulmonary disease (COPD). Methods The Web of Science core collection database was searched to collect literature on traditional Chinese exercise for COPD rehabilitation published from 2004 to 2023. VOSviewer was used for bibliometric analysis of publication year, author, publication institution and country, citation and co-citation information. Results A total of 125 publications were included. No relevant publication was published from 2004 to 2008. Since 2009, the overall number of publications had shown a fluctuating upward trend, with no publications in 2012. From 2019 to 2023, the number of publications on related topics remained at a high level. Reached maximum publication volume in 2020. The annual citation frequency also showed a fluctuating increase, reaching its peak in 2022. Based on comprehensive analysis, Peter M. Wayne and Wu Weibing were the authors with high productivity, high citation, and frequent collaborations. The country with the highest number of publications was China, and the highest institution was Shanghai University of Sport. Initially, the keywords focused on rehabilitation, exercise testing, aerobic exercise, resistance exercise, and respiratory muscle strength. As the times progressed, the focus shifted to lung function, exercise tolerance, and mental health. The current trends included self-management and telemedicine. Conclusions Traditional Chinese exercises have been widely applied in the clinical practice of COPD rehabilitation, showing an upward trend.

Objective To discover the similarities and differences between CBM and MEDLINE databases in the field of post-earthquake health issue research characteristics in order to provide references and aids to the scientific research administration, professional education and training, research subjects selection and project finance support. Methods CBM and MEDLINE databases (from January 1987 to December 2009) were systematically searched to obtain literature about post-earthquake health issues. Those studies were classified and compared by the characteristics of research objects, health issues, research periods, and types of study design. Results A total of 701 literature from CBM and 387 from MEDLINE were included. MEDLINE database provided more studies focusing on victims of natural calamities with specific age description than CBM (Plt;0.05). Research peak of CBM database centralized in the period of three months after earthquake (n=645, 92%), while MEDLINE was three years after the earthquake (n=191, 87.2%). Studies from both databases similarly focused on physical trauma and psychiatric/psychological issues (two types of health issues in total: CBM: n=727, 86.1%; MEDLINE: n=358, 83.4%). Investigations from CBM were primarily designed for retrospective and descriptive research (n=439, 62.6%), cross-sectional investigations (n=146, 20.8%) and case report (n=86, 12.3%) while MEDLINE focalized on cross-sectional investigations (n=177, 45.7%) and retrospective and descriptive research (n=146, 37.7%). Conclusion Compared to MEDLINE, studies from CBM database are relatively weak in the post-earthquake health issues of population with specific age characters, long-term health issues, levels of evidence and types of research design. The possible reasons are insufficient attention to the post-earthquake health issues, inadequate preparation for the research or limited knowledge about research methods.

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.

Objective To provide some theoretical reference and practical guidance for the medical risk management and early warning of private medical institutions, and to improve the service level and social reputation of private medical institutions. Methods China National Knowledge Infrastructure, Wanfang, VIP, and Web of Science database were searched for literature on medical risk management of private medical institutions published from the dates of establishment of databases to July 31, 2023. CiteSpace software was used for analysis. The aspects of literature number, literature source, author-institution cooperation, keyword co-occurrence, keyword clustering and burst were analyzed. Results A total of 2 635 literature were detected. Among them, there were 1446 articles in Chinese and 1189 articles in English. Although domestic research started late, it covered a wide range of disciplines and research fields. The Chinese literature showed a growth trend in the medium term, but the growth trend was slower than that of foreign literature. At the same time, the cooperation network of foreign authors and institutions was closer than that of domestic ones, and the overall development was relatively insufficient. There were differences between domestic and foreign research hotspots in terms of disciplines and research contents. Conclusions It is necessary to strengthen the theoretical and practical research on medical risk management of private medical institutions, and accelerate the construction of risk management and early warning models suitable for the characteristics of private medical institutions in China. In the future, the emerging research fields such as moral hazard, emergency and internal control need to be deepened and expanded.
Objective To investigate the current status of esophageal cancer surgery-related researches using bibliometric methodologies and identify the trend and hotspots. Methods The Chinese and English literature was collected from Web of Science and CNKI from inception of each database to April 1, 2022. VOSviewer 1.6.18 and CiteSpace 6.1 were applied to cluster the authors, institutions, and keywords. For social network and time series analysis, Excel, GraphPad, and R 4.0.3 were used to visualize the literature on esophageal cancer surgery. Results Finally, 19 566 English literature and 19 872 Chinese literature was included. The results demonstrated that the annual publishing of both Chinese and English literature increased over time, with English literature increasing rapidly and Chinese literature maintaining an average number of above 1 000 per year from 2011 to 2019. Researches were predominantly centered in Europe, the United States, Japan, South Korea, and China. China's researches in the field of surgical treatment in esophageal cancer lacked international collaboration, which began later than East Asian countries such as Japan and South Korea and had less influence. From the keyword perspective, previous researches on surgical treatment of esophageal cancer mostly focused on surgical techniques, complications, and comprehensive perioperative therapy. Both Chinese and English literature showed that the prevalence of keywords such as minimally invasive surgery, comprehensive treatment, and clinical trials increased dramatically during the recent years, indicating that these fields may represent the future directions and research trends. Conclusion Compared to East Asia countries, such as Japan and South Korea, Chinese esophageal cancer surgery-related researches are relatively lacking. The research direction and field are similar to those in developed countries such as the United States and Europe. Future attention may be focused on minimally invasive treatment, comprehensive treatment, and clinical trials associated with surgical treatment of esophageal cancer.
