RESUMEN
Evidence-based medicine,which can be told from its name,is a new medical model based on evidence.The methodology of the research and thinking pattern of evidence-based medicine is philosophical,thus could be entirely applied to the fields of natural sciences,social sciences,and noetic sciences.The concept of best evidence in evidence-based medicine makes it necessary for us to take a second consideration for the function of medical experts.Its behavioral pattern which shows an overall care for patients from spiritual aspects to material aspects,from hospitalized period to a whole lifetime,from the clinical treatment to post-discharge living quality has truly sublimated ethical care to a new era.
