Abstract

Many sources of evidence exist between the anecdotal experience of expert clinicians and quality studies that are done at individual institutions. This chapter deals primarily with published sources of evidence, such as journal articles and books. When faced with a journal article or textbook chapter, the informaticist must be able to critically analyze the presented information to assess its value.
