The purpose of this paper is to explore the strategy of future Korean medicine(KM) clinical research through the study on the proposals for KM clinical research worldwide. In this study, the papers published in English through Pubmed were investigated mainly. Among them, we analyzed the methodological proposals from the clinical research papers that were published in the KM related fields. Various proposals for improving the problems in KM clinical studies are as follows. First, KM clinical research should be designed based on understanding for the theory, backgrounds, paradigms and worldviews of KM. In addition, considering the model validity, KM clinical research model should include the diagnosis, interventions and outcomes measurement methods reflecting the characteristics and real practice in KM. The internal validity and external validity should be also taken into account. One of the most important thing is to identify the contents about various and complex "real practice" in KM. A prospective observational study was suitable for the purpose of this study. Finally, we suggested a few improvement directions for RCTs studies in KM. First, we would be able to improve the quality and the internal validity in KM clinical research using the checklists of CONSORT(Consolidated Standards for Reporting Trials) Statement and STRICTA(Standards for Reporting Interventions in Clinical Trials of Acupuncture). Second, we could use various clinical research methods and the modified research of RCTs such as PCT(pragmatic clinical trial) to reflect the characteristics of actual KM practice. Consequently, we would be able to improve the external validity. Third, the KM diagnosis and outcomes measurement methods should be developed based on an actual KM practice and it should reflect a real practice. The "pattern identification(辨證)" is the core to KM diagnosis. But in order to be applied to the clinical research, the pattern identification(辨證) should be objectified and standardized. Future KM clinical research model should reflect the characteristics and a real practice in KM. In addition, it should include the advantage of rigorous RCTs research. Specially, the diagnosis, interventions and outcomes measurement methods in KM clinical research should reflect this view.
