Objective To investigate how many hospitals can perform vitrectomy and its relationship to economic development in China.Methods Bibliometric data of retina-vitreous literatures were searched from the China National Knowledge Infrastructure (CNKI) academic databases. We used pars plana vitrectomy (PPV) as a keyword and defined address as mainland China, limited years to 1993 -2009. From those data we analyzed which hospital performed PPV. We also communicated with some hospitals by phone, email to confirm if they were performing PPV. Gross domestic product (GDP), population data and economic development ranking were extracted from the China Statistical Yearbook 2009 (National Bureau of Statistics of China). PPV carry-out rate, PPV-hospital shares and their relationships with the GDP in each regional municipality were analyzed.Results All together this study retrieved 4632 articles meet our requirements. There were 340 hospitals carrying out PPV in mainland China, located in 22 provinces, five autonomous regions and four metropolitan municipalities. The top five provinces with higher PPV carryout rate were Shandong (93,75%), Zhejiang (90,00%), Hebei province (90.00%), Jiangsu (83.33%) and Guangdong (75.00%). There was significant difference in per capita share of PPVhospitals between different cities (chi;2=181,153，P=0,000) and in the PPV carry-out rate between different cities (chi;2=749.217，P=0.000). There were 210 private eye hospitals in China,62 hospitals (18.23%) of them could perform PPV included 39 hospitals located in regionallevel cities. The coefficient correlation between PPV and GDP of different provinces was 0.842 (P=0.000). Conclusions Vitrectomy is widely performed in mainland China, but geographical distribution of PPV-performing hospitals is uneven. PPV performance is closely related with regional economic development,and private hospitals play certain roles in promoting the application of vitrectomy.

ObjectiveTo explore the current status of nursing researches about catheter-related infections in recent 5 years in China, and provide reference for further research.MethodsThe China National Knowledge Infrastructure database and Wangfang database were selected to search for literature about catheter-related infections published in recent 5 years in 10 nursing journals of Statistic Source, with the terms of " catheter-related bloodstream infection” or " ventilator-associated pneumonia” or " catheter-related urinary tract infection”. Statistical analysis was conducted.ResultsA total of 216 papers were included. The number of papers was not increased year by year. In terms of the object of study, the studies on ventilator-associated pneumonia were the most, accounting for 71.3%. Only 36.5% of the studies had accurate diagnostic criteria. In terms of the type of study, experimental studies were the most (109 articles). The content was concentrated on the best practice intervention studies (149 articles). The data collection methods gave priority to active surveillance/screening, including 113 articles.ConclusionsThe present focused attention is not enough to the researches about catheter-related infections in nursing field, and rigorous design is lacking in published studies. There are only a few nursing studies about catheter-related infections with high quality and high level of evidence. The quantity and quality of nursing researches about catheter-related infections still need to be improved. Nurses should pay more attention to the control and prevention of catheter-related infections, and should improve their research capacity.
ObjectiveTo analyze the application status of Kanban management in medical service management at home and abroad and to provide a reference for lean medical management practice in China.MethodsUsing the bibliometric method, in China National Knowledge Infrastructure, Wanfang Database, CQVIP Journal Database, Springer Link, Embase and PubMed, we used “Kanban” and “Kanban management” as Chinese search terms, “Kanban system” and “two-bin system” as English search terms to search for literature published from 2009 to 2019. The number of articles published, institutions, authors, citation frequencies, key words, Kanban usage, and improved areas where Kanban was applied in were statistically described and analyzed.ResultsA total of 219 articles were retrieved. Of the 14 articles included in the study, 12 articles were published from 2015 to 2019, 8 articles were published by hospitals, and 9 articles were cited more than or equal to 3 times. The key words were basically the combinations of Kanban and related topics in the field of medical service management, such as quality control and improvement, ward service, high-quality care and process evaluation; 11 articles used Kanban alone. Kanban was used in medicine supply chain management, ward bed management, and material inventory management abroad; and was used in medicine management, emergency room patient management, medical staff performance management, operating room equipment management, and high-quality medical service management in China.ConclusionsKanban as a lean management method was introduced into the domestic medical field late, and the current research development is not balanced. Asa visual management tool, Kanban needs to be extended in the medical field. As a lean improvement tool, Kanban has positive significance in improving medical quality and patient satisfaction. It is suggested that researchers should not be limited to the existing applied research, and can study the application of Kanban in different medical service fields in combination with different lean management tools according to the actual situation of the hospital.

Objective To analyze the research status and development trend of evidence-based social sciences, and to explore the synergistic relationship among branches of various fields. Methods A comprehensive search for research related to evidence-based social sciences published between the establishment of the database and September 2022 was conducted on the Web of Science, China Science Citation Database (CSCD), and Chinese Social Sciences Citation Index (CSSCI). The VOSviewer software was used to analyze the author and keywords and to perform the visualization. Results A total of 6 969 papers were included, 195 of which were in Chinese. The first paper, published in 1995, was on evidence-based management. The number of papers published on evidence-based social science research presented a trend of increasing continuously. The country with the most papers published was the United States; the institution outside China with the most papers published was McMaster University; and the institution in China with the most papers published was Sichuan University. The analysis of keywords showed that evidence-based policy, evidence-based practice, evidence-based management, and evidence-based decision-making appeared more frequently; research questions focused on evidence-based health policy development, application of big data in the context of COVID-19, evidence of climate change-induced disease, and real world research. Conclusion All the fields of evidence-based social sciences are closely related to each other in terms of research content and methods, and it presents a multi-level and multi-field crossover with evidence-based medicine. However, evidence-based social sciences in China are still in their infancy. Therefore, it is necessary to improve the methodological system of evidence-based social sciences, enrich the research content of social sciences, speed up the filling of evidence gaps in various fields, and promote the improvement and sustainable development of evidence-based social sciences.
