Evidence-based medicine (better known as EBM) is defined as "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients." [1].
Evidence-Based Health Care extends the application of the principles of EBM to all professions associated with health care, including purchasing and management [2].
Practicing clinicians usually cite the lack of time for reading newer textbooks or journals. However, the emergence of new types of evidence can change the way doctors treat patients. Unfortuantely the recent scientific evidence gathered through well controlled clinical trials usually do not reach the busy clinicians in real time. Another potential problem lies in the fact that there may be numerous trials on similar interventions and outcomes but they are not systematically reviewed or meta-analyzed.
An essential adjunct to the practice of evidence-based medicine (EBM) is medical informatics (MI) which focuses on creating tools to access and apply the best evidence for making decisions about patient care [Sackett et al, 2000].
Before practicing EBM, informaticians (or informationists) must be familiar with medical journals, literature databases, medical textbooks, practice guidelines, and the growing number of other dedicated evidence-based resources, like the Cochrane Database of Systematic Reviews and Clinical Evidence [Mendelson and Carino 2005].
Similarly, for practicing medical informatics properly, it is essential to have an understanding of EBM, including the ability to phrase an answerable question, locate and retrieve the best evidence, and critically appraise and apply it [Hersh 2002, Shearer et al., 2001].
