Evidence-based medicine is an evidence-based medical practice method, which aims to make the best medical decision by evaluating the latest clinical research evidence and combining the professional experience of doctors and the values of patients. Its core is to systematically collect, evaluate and apply the latest research evidence to support doctors to make more accurate, reliable and effective diagnosis and treatment decisions in clinical practice.

The methods of evidence-based medicine include:

Ask clear clinical questions: Doctors need to ask clear clinical questions in order to find the latest research evidence.

Collect the latest research evidence: doctors need to find the latest clinical research to get the latest treatment methods and techniques.

Evaluate the quality of evidence: doctors need to evaluate the collected evidence to determine its quality and reliability.

Applied evidence: Doctors need to make the best treatment plan according to the evaluated evidence, combined with their own professional experience and patients' values.

The purpose of evidence-based medicine is to improve medical quality, reduce medical errors and improve patient satisfaction. It has become the core of modern medical practice and is widely used in clinical practice, medical education and medical research.
