The main progress of evidence-based medicine over the traditional clinical medicine model is the increased emphasis on the use of information technology.

Evidence-based medicine (EBM), meaning "evidence-based medicine", also known as empirical medicine, and also translated as evidence-based medicine in Hong Kong and Taiwan, is an approach to medical diagnosis and treatment that emphasizes the optimization of decision-making through the application of well-designed and executed research (evidence). It emphasizes the application of well-designed and executed research (evidence) to optimize decision-making.

There are important differences between EBM and traditional medicine. Conventional medicine is based on personal experience, with physicians handling patients based on their own practical experience, guidance from senior physicians, and scattered studies in textbooks and medical journals. The result is that some truly effective therapies remain unadopted in the clinic for long periods of time because they are not known to the public; some actually ineffective or even harmful therapies are used for long periods of time, widely, because it is inferred theoretically that they may be effective.

The practice of evidence-based medicine emphasizes both personal clinical experience and the use of the best available research base. An excellent clinician should have a wealth of clinical experience and be able to rely on the best available scientific evidence to guide clinical practice, both are indispensable. This best available scientific basis mainly refers to the clinical research basis. Basic theory or animal testing is used as a reference in the absence of clinical research, because the human body is much more complex than animals and has many influencing factors.

Evidence-based medical treatment research basis according to the quality and reliability can be roughly divided into the following five levels (the reliability of the decreasing order):

1, level 1: in accordance with the specific treatment of a particular type of disease collection of all the quality of the reliable randomized controlled trials made after the systematic evaluation or Meta-analysis.

2. Level II: Results of individual randomized controlled trials with adequate sample size.

3. Level III: Studies with a control group but not grouped by randomization.

4. Level IV: A series of case observations without controls, which are less reliable than the two above.

5. Level V: expert opinion. In the absence of these gold standards, other levels of evidence may be used as a reference point but it should be made clear that their reliability decreases accordingly, and that they should be used as soon as possible when higher levels of evidence become available at a later date.
