Abstract

Evidence-Based Medicine (EBM) is a method that uses best evidences in decision-making of clinical practice for certain patient in his/her special situation, regarding reliability and efficacy of evidences. EBM needs clinical skills, information retrieval expertise (i.e. PICO search strategy), appraisal and critical thinking, and applying findings to reduce risks and improve care processes.
So EBM users continue Evidence-Based Practice captured in 5A (Ask, Acquire, Appraise, Apply and Assess) to create a Critically Appraisal Topic (CAT) (2, 5). They use some tools like Journal Club in Appraise of quality (5). Other way of Quality control of evidences is to classify them in three or four Levels(1) to determine the Best Evidence. These levels ranked by the type of evident studies. For example Systematic review is base stone of EBM,(4) Randomized Control Trials (RCTs), Clinical Trials, etc. are other useful types.
Most famous pioneers of EBM are Avicenna in his book The Canon of Medicine in the 11th century(3,6) and A. Cochrane, D. Sackett, and G. Guyatt in the 20th century(1). Nowadays
some websites and databases like Cochrane.org, Cochrane Library, TRIP Database, and BMJ.com(1) made available EBM documents.

You gave nice ideas here. I done a research on the issue and learn most peoples will agree with your blog. Certainly, these practices are unfair; but they say that most of their rules are only to apply to people who overdraw.
