Visualization studies on evidence‐based medicine domain knowledge (Series 1): Mapping of evidence‐based medicine research subjects

Abstract

Objective To use visualization methods to illustrate and compare major subjects, domains, and developments in evidence-based medicine (EBM) in recent years. Method We analyzed MeSH terms and keywords in EBM articles in the MED-LINE and CNKI databases, and developed subject charts, research field relationship charts, and strategy coordination charts using word co-occurrence, PFNET algorithms, and visualization methods. Result Rapid developments and growth are taking place in EBM in China and around the world. Studies on humans comprised 94.4% of the EBM studies that we identified, while animal studies accounted for 2.6% (three quarters of these animal studies were on primates). The six countries with the largest number of EBM articles and the eight host nations for the 108 journals with the most EBM publications were from high-income countries. In China, 31 provinces, municipalities, and autonomous regions have published EBM articles, although most of these publications come from the more highly-developed areas of the country. The investigation of word co-occurrence showed that EBM articles outside of China involve seven main fields: "Therapy", "Methods", "Standards", "Research", "Education", "Nursing" and "Organization and Administration". Five of these fields ("Therapy", "Nursing", "Research", "Education" and "Management") were common to China but the top seven fields for this country included "Traditional Chinese Medicine (TCM)" and "Information resources"; and did not include "Methods" and "Standards". Furthermore, studies on "Nursing" and "Research" were not as advanced in China as in other countries. Conclusion There are similarities between China and the rest of the world in several areas in the EBM literature but also some important differences. Throughout the world, the most resource-rich regions o organizations tend to have the most welldeveloped EBM. These regions and organizations are pdocuing more evidence and conducting more methodology research than the less resourced regions and organizations. There is an urgent need for these regions and organizations to strengthen their use of evidence, to learn more about the philosophy that underpins EBM, and to improve accessibility to, and use of, evidence in choices about health care.JEBM 4 (2011) 73-84 c 2011 Blackwell Publishing

Challenges and a response strategy for the development of nursing in China: a descriptive and quantitative analysis

“…This is evident in the difference in the relative strength of nursing in evidence‐based medicine between China and other countries (67.1 vs. 18,365.8; ref. ). It has been suggested that nursing studies in China are greatly lacking compared with other countries, both in terms of their breadth and depth.…”

Visualizing the history of evidence‐based medicine: A bibliometric analysis

“…In clinical practice, EBM has been introduced into evidence‐based TCM, evidenced‐based nursing, evidence‐based quality management, and other domains. Studies on evidence‐based nursing account for a large proportion, but most are less creative with shallow research depth compared with relevant studies abroad (Shen et al., ). Furthermore, evidence‐based management in China requires further exploitation and development as it is still in its early stages.…”

Clinical research activity in periodontal medicine: a systematic mapping of trial registers

“…We used the 2015 Medical Subject Headings (MeSH ® ), from the U.S. National Library of Medicine, as already done in other mapping research (Shen et al. , Komenda et al. ).…”

“…We used the 2015 Medical Subject Headings (MeSH Ò ), from the U.S. National Library of Medicine, as already done in other mapping research (Shen et al 2011, Komenda et al 2015 As the same MeSH terms are often found in several sub-branches, we drew up a simplified, tailored thesaurus to avoid redundancy in the mapping process (the one exception being for kidney diseases, where no distinction could be made between male and female disorders). We also considered the [Phenomena and Processes -G] branch, because it contained some possible relevant health conditions, such as pregnancy or menopause.…”
