There are now five classic steps for analysis of diagnostic and therapeutic medical decision-making policies: (1) formulate a clear clinical question based on a particular patient’s problem; (2) search the literature for relevant clinical articles; (3) evaluate the evidence for its validity and usefulness; (4) implement useful findings into clinical practice; (5) audit the validity of the process. The clinician must have the necessary skills to appraise critically the information retrieved. Rather than focusing on the discussion and conclusion sections of articles, the reader should concentrate on the review of the methods and results sections to formulate an opinion regarding the strength of evidence presented in the paper. The process is intellectually demanding and difficult to achieve. This particular step in the validation of evidence implies that each clinician must be methodologically and statistically sound, an “expert,” capable of analyzing the method used in that particular publication to achieve the published result.
