To explore the focus and trends in real-world studies in Chinese through knowledge mapping method, databases CNKI, VIP, Wanfang and Sinomed were retrieved, with 1 757 relevant articles published before September 30rd, 2020 finally included, whose bibliographical records were imported into NoteExpress to avoid duplication and check relativity. VOSviewer, a bibliometric analysis tool, was used to analyze their development. It was found that real-world studies have mainly taken shape after 2010, in which traditional Chinese medicine research plays an important role. China Journal of Chinese Material Medica was the leading journal with 120 papers, the China Academy of Chinese Medical Sciences the most contribution institution with 338 papers, and Xie Yanming from the institution the most contribution author with 250 papers. This study helps clinicians and researchers in better understanding the evolution of real-world research over more than two decades in China.
In recent years, the concept of population medicine has emerged as a research field that has important implications for healthcare practice and policy decision-making. It specifically aims to improve overall health of patient populations and safety, quality and efficiency of healthcare system. This paper descried the background, definition and characteristics of population medicine, discussed relationship between population medicine and population health and evidence-based medicine. It also introduced Department of Population Medicine at Harvard Medical School as a world-class model in the field of population medicine, discussed the needs and potential strategies for developing population medicine research in China, and briefly outlined the current development of population medicine in China.
ObjectiveTo construct the comprehensive evaluation indicator system of Chinese patent medicines for ischemic stroke, to determine the weight of indicators, and to provide references for the comprehensive evaluation of the efficacy, safety, and economy of Chinese patent medicines.MethodsTwo rounds of expert consultation by Delphi method were applied to establish the comprehensive evaluation indicator system of Chinese patent medicines for ischemic stroke, and the weight of each indicator was determined by the analytic hierarchy process method.ResultsQuestionnaire recovery rates of 2 rounds were 92.59% and 96.00%, the expert authority coefficient was greater than 0.7, and the coordination coefficients of experts in the total index were 0.224 and 0.370 (P<0.001). A three-level comprehensive evaluation indicator system for Chinese patent medicines for ischemic stroke was established and the three first-level indicators included efficacy, safety, and economy. And there were 15 second-level indicators, and 33 third-level indicators. Through the analytic hierarchy process method, the weights of each first-level indicator were 0.626 4, 0.301 2, and 0.072 4, respectively.ConclusionThe comprehensive evaluation indicator system contains efficacy, safety and economy, and provides a basis for a comprehensive evaluation of Chinese patent medicines for ischemic stroke. The indicator system is of great significance for the design of outcomes for clinical trials of ischemic stroke, the conduction of systematic reviews, and the development of clinical practice guidelines for ischemic stroke patients when selecting study outcomes.
