ABSTRACT
Objective@#To comb the thread and trend of critical care fields in China for nearly 15 years, analyze research frontiers, demonstrate research evolution paths, provide reference for researchers and clinicians to carry out related work.@*Methods@#Using CiteSpace software and CNKI database to retrieve research literature about critical care from 2004 to 2018 in China for visual analysis.@*Results@#A total of 3 049 valid articles were retrieved. The research frontiers were mainly about emergency and critical nursing, nursing quality management, intensive care, clinical teaching quality and ICU nurses. Research trends from critical care, critically ill patients, disease condition change, to quality control, family members, nursing skills, basic nursing, now gradually turned to humanized care, nursing strategies, sustainable human care concepts, evolution map showed that emerging trend was more active.@*Conclusions@#In last 15 years, research fields of critical care in China have evolved actively, exploring research frontiers, focus on important topics such as evidence-based nursing,humanistic care nursing concept, intensive care information system, and cluster management strategy, extending and deepening professional development of critical care.
ABSTRACT
Objective To analyze the development trend of global and domestic major disaster medical rescue, pre-dict the development trend of key technologies in major disaster medical rescue, and put forward suggestions for the distribution of resources and technical training model in domestic major disaster medical rescue by investigating and comparing the researches in domestic major disaster medical rescue. Methods Data of disaster medical rescue were analyzed using the scientific knowledge mapping analysis tools ( TDA and VOSVIEWER) with the Web of Science Database-covered titles of papers on disaster medical rescue in 1995-2017 as the study objects. Results A total of 1333 titles of papers on disaster medical rescue were retrieved from the Web of Science Database, from which 89 high frequency co-occurrence key words in 7 major categories were selected. Conclusion The research on crush syndrome, posttraumatic stress syndrome, fracture, spinal cord injury, rehabilitation, casualty classification, and field hospital is advantageous over that on telemedicine, communication, pediatrics, personal identification and education in domestic major disaster medical rescue. Disaster rescue system should be established, research on disaster rescue concept, techniques and equipments should be deepened, and training model of emergency medical rescue should be expanded in our country.
ABSTRACT
After a description of the concept of research frontier, advantages and disadvantages of qualitative and quantitative research frontier analysis methods, application of qualitative and quantitative research frontier analysis methods and existed problems, it was pointed out that the automatic detection method of heterogeneous data source text mining was a trend for the research frontier identification methods.
ABSTRACT
Objective To analyze the history and present situation of international medical device with visualization softwareto provide references for medical device development in China.Methods CiteSpace visualization software was used to explore international literatures related to medical device from the aspects of yearly quantity,research direction,research organization,quoted literature and etc from 2005 to 2014.Results Medical device drew increasing attention from corresponding researchers,whose development depended on international cooperation.Medical device related closely to engineering and medicine,and had to paid attention to informatization and clinical requirements.Conclusion CiteSpace software is of great value for the study on medical device.
ABSTRACT
Objective To study the intellectual base and research frontiers detected in journals of general medicine and internal medicine by biclustering. Methods The intellectual base and research frontiers in journals of general medicine and internal medicine with a high IF were detected by biclustering analysis of their data using gCLUTO. Results The research frontiers detected in recent journals of general medicine and internal medicine showed that the combination of clinical epidemiology and EBM with clinical medicine was more and more concerned by clinicians. Conclusion Biclustering can detect the intellectual base and research frontiers in journals of general medicine and internal medicine, and can thus be popularized in assessing the development of subjects in different fields.
ABSTRACT
Papers on electronic health record ( EHR) were retrieved from CNKI core journals database and CNKI patents full-text database.The papers on HER and patent literature were comparatively analyzed by co-words clus-tering analysis, which showed that technologies used in community health service, remote medical treatment, HL7 and XML are the promise technologies used in EHR.
ABSTRACT
A co-word matrix was constructed with PubMed-covered papers on breast cancer-related enzyme from 2009 to 2011 and from 2012 to 2014 as its data source.The papers were double clustered by gCULTO to generate class groups and identify the breast cancer-related enzyme research frontiers and the evolution of different class groups.
ABSTRACT
Objective To analyze the course of development of chronic fatigue syndrome ( CFS) and its research hotspots and frontiers .Methods We retrieved 3723 CFS-related papers published in the Web of Science databases between 2000 and 2014, and obtained a series of mapping knowledge domains with the help of the CiteSpace Ⅲ.Results By visually analyzing the network of international cooperation , mainstream academic communities , development trends and research hotspots in the field of CFS ,the classical literature was quickly decided on and reviewed so that research frontier and development trends were accurately defined .Conclusion Our analysis shows that the academic communities in the field of CFS are mainly located in the United States ,England and other Western countries .Research hotspots shifted from case characters to influence factors ,mechanisms and therapeutic methods .Currently,research frontiers are the etiological theory of pathogen infection and the pathophysiological mechanisms of similar chronic diseases .
