Successfully improving the health and function of patients are the common goals of physicians and patients. Modern medicine progresses rapidly, with various medical technologies, equipment and drugs being developed. In addition, coexistence of newly developed and old medical options, physicians having their own or preferred treatment techniques and strategies, and medical conditions as well as medical systems are also different. Therefore, a new method is needed for doctor-patient communication. Such a system has to take into account of human rights concepts, evidence-based medical data, while considering feasibility, optimal timing, patient preferences and expectations, related legal responsibilities, insurance payment and satisfaction, etc. Before medical treatment, both health providers and patients need to fully communicate and negotiate the appropriate medical options, i.e., shared decision-making, SDM. Since its introduction, SDM has become widely accepted. However, medical systems and insurance systems are different among countries. When health providers explain to patients about treatment options and risks, a big gap may exist between evidence-based data and expert clinical treatment guidelines. Furthermore, even though the advance of medicine is rapid, an innovative medical option needs to be verified after a period of time before evidence-based results can be assessed. Therefore, during the communication between doctors and patients, it is inevitable that there is a possibility of suboptimal understanding. These aforementioned factors may be an obstacle to the implementation of ＂sharing decision-making＂. Furthermore, many uncertainties of disease itself and unexpected situations arising during the course of treatment may cause the necessary change of original treatment plan. Treatment of major or emergency diseases are mostly explained and recommended by doctors who also violate the autonomy of patients and fail to meet the substantive requirements of ＂sharing decision-making＂. These factors have become the major challenges in the implementation of ＂sharing decision-making＂. This article discusses the relevant myths and provides some suggestion of solutions, thus help promoting ＂sharing decision-making＂.
