Since the term "evidence-based medicine (EBM)" was proposed and published firstly in JAMA by a Canadian scholar in 1992, a worldwide campaign of evidence-based practice has been undertaken which has benefited governments, doctors and the public. It has not only brought innovation to the global health industry, but been applied to many other related fields and industries. As a result, EBM was appraised by JAMA as one of the most powerful theories of the 20th century.
