What should be noted in learning evidence-based medicine?

Problems to be noted in learning evidence-based medicine:

(1) Pay attention to the dialectical relationship between evidence-based medicine and traditional medicine: Although traditional medicine is mainly based on the practical experience and intuition of medical personnel to diagnose and treat patients, and the evaluation of the diagnosis, treatment, and prognosis of the patients is based on the basis of the clinical experience of the non-buy-in test and the understanding of the mechanism of the disease, but the traditional medicine also emphasizes on evidence, only that there is no strict regulation on the acquisition, analysis, organization, application, and evaluation of the effect of the evidence. However, traditional medicine is also concerned with evidence, only that there are no strict regulations on the acquisition, analysis and organization, application and evaluation of the effect of evidence. Evidence-based medicine requires systematic and comprehensive rules for information retrieval, analysis and organization, application and effect evaluation, but evidence-based medicine cannot replace the historical experience of traditional medicine in clinical skills, clinical experience and collection and analysis of clinical data, etc. The evidence obtained must be combined with the clinical data and information to make judgments and make careful decisions on whether to use it for specific patients. Therefore, evidence-based medicine does not contradict traditional medicine, but provides more scientific and improved clinical data and information. Modern medicine emphasizes the organic combination of the two.

(2) Correctly view the relationship between evidence-based medicine and randomized controlled trials: Although randomized controlled trials are the best research method in evidence-based medicine literature search and evidence evaluation, evidence-based medicine is not just the results of a randomized controlled trial as the basis for diagnosis and treatment, but in accordance with the problem to be solved, under strict design conditions, comprehensively collect evidence, according to the evaluation criteria for the Its score, if the design of the randomized controlled trial is reasonable and scientific, but also according to the specific circumstances of the patient to decide on the use of its results or not.

(3) Note the limitations of evidence-based medicine: ① Although evidence-based medicine will greatly improve the quality and efficiency of health care services, it is not able to solve all problems related to human health, such as the social environment, natural environment and genetic factors. ② Establishing an effective system for generating, summarizing, disseminating and utilizing medical evidence will cost a certain amount of resources, and therefore, to a certain extent, it will rather increase healthcare costs in a short period of time. ③ It creates difficulties for the implementation of evidence-based medicine due to the influence of various factors. ④Medical decision-making is a very complex issue, and in a situation of limited resources, decision-makers have to make certain concessions when they have to take into account the interests of individuals and society, and in the face of economic and ethical issues of principle.
