The basic concept of evidence-based medicine proposes to make health-related decisions based on a synthesis of internal and external evidence. Internal evidence is composed of knowledge acquired through formal education and training, general experience accumulated from daily practice, and specific experience gained from an individual clinician — patient relationship. External evidence is accessible information from research. It is the explicit use of valid external evidence for example, randomized controlled trials, combined with the prevailing internal evidence that defines a clinical decision as evidence-based.
