Evidence Based Medicine (EBM)
Evidence Based Medicine is an approach to forming medical knowledge, based on systematic and unbiased methods of appraising scientific evidence. It addresses the problems of medical practice based on tradition and personal opinion, and has gained wide acceptance over recent years.
It is outside the bounds of this website to provide a comprehensive review of the principles and practice of EBM. However, some information can be gleaned from the other pages and papers listed on the site.
An excellent introduction to practical EBM is provided by David Sackett's book "Evidence Based Medicine: how to practice and teach EBM" (ISBN 0443062404). See the Evidence Based Medicine links page for some excellent websites about EBM.
