What is evidence-based medicine?

It advocates combining the personal clinical practice and experience of clinicians with objective scientific evidence to provide the most correct diagnosis, the safest and most effective treatment and the most accurate prognosis estimation for each specific patient. Evidence-based medicine is different from traditional medicine. Traditional medicine is based on empirical medicine, that is, treating patients according to non-experimental clinical experience, clinical data and basic knowledge of diseases. Evidence-based medicine does not want to replace clinical skills, clinical experience, clinical data and medical expertise, but only emphasizes that any medical decision should be based on the best scientific evidence. In recent years, with the rapid development of evidence-based medicine, network resources are becoming more and more abundant. Cochrane Library, founded by Cochrane Collaboration Network, has become an important database for obtaining evidence-based medical resources, and its high-quality systematic review is regarded as the best source of scientific evidence. With the rapid development of computer, modern communication technology and biomedical informatics, many well-known biomedical databases, such as MEDLINE, EMBASE, BIOSIS, SCI and China Biomedical Database, have changed from CD-ROM to network, enabling medical professionals to conduct comprehensive and unbiased literature search on the Internet, and then obtain abstracts about a specific clinical problem, but the contents of abstracts can not fully meet the information needs of evidence-based medical system evaluation. At present, the emergence of a large number of online journals has prompted information service organizations and publishers to provide integrated services from keyword query to abstract to original text, providing medical professionals with the opportunity to obtain original texts directly online, including the famous full-text database OVID which provides evidence-based medical resources and the largest full-text database in China, China Journal Network. In addition, with the rise of evidence-based medicine, its website is becoming more and more perfect, covering almost all aspects of evidence-based medicine: systematic review database, clinical practice guide database, evidence-based medicine journals, meta-analysis software, evidence-based medicine teaching resources and navigation, Meta-. Many of these resources are free, and some have become important websites for clinicians to access evidence-based medicine resources.
