Medical Student Perspectives: Evidence-Based Medicine Resources for Medical Students

Physicians have been practicing based on “evidence” for many decades. However, traditionally due to multitude of reasons, including limited availability of sound clinical research and limited access to available data, they heavily relied on anecdotal evidence, which was primarily derived from their clinical experience, the recommendations of their colleagues and the writings of the “authorities” in their field. Over the past two decades, with the advances in technology, in particular the advent of the electronic age, the ability to disseminate more objective evidence has greatly increased and there has been a shift toward relying more on such evidence over the anecdotal approaches of the past.

The term “Evidence-Based Medicine” (EBM) with its modern meaning was first coined by Dr. Gordon Guyatt and his team in a 1992 publication in the Journal of the American Medical Association(JAMA). Later EBM was defined by Dr. David Sackett as “the conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient.”

Since its formal introduction, EBM has gradually become the standard for the practice of medicine. As future physicians, we will be practicing in an environment that requires detailed knowledge and regular practice of EBM. However, not all studies meet the threshold for integration into daily clinical practice and require careful evaluation by the reader. Given the rigorous curriculum of medical school and the vast number of studies that are published on a daily basis, it is impossible to critically evaluate each and every study to extract relevant data. Therefore, it is important to identify reliable resources that provide high-quality evidence for various clinical needs. The following list identifies a number of these resources, which at the time of this publication are free to medical students. It must be noted that this is not a comprehensive list of all available resources, and some of the following sites may require registration for free membership prior to use.
