The Centre for Evidence Based Medicine http://www.cebm.net/ in Oxford is a great resource, with EBM tools, youtube channel packed with useful films, a reading list to with all the basics, and much more (I particularly love “evidence based medicine and baking“…)

It’s blog is great too – read the post on “5 tips to jumpstart your evidence based practice“ – always difficult when you’re pressed for time.
