Key message:

Evidence-Based Medicine in a nutshell from first principles to medical statistics in the course of one free article. You can read the article in full for free here.

Who is the article for?

This article by Dr Dean Hess was originally published in the journal ‘Respiratory Care’ in 2004. Hess assumes very little prior knowledge, starting by defining the basic principles of Evidence-Based Medicine (EBM) and building form there one step at a time. It is full of clinical examples of how EBM can be put into practice. This article is particularly helpful for students of healthcare professions, for whom the clinical examples are most relevant, but could be understood by an educated lay audience.

I am very busy, how long will it take me to read?

The article is nine fact-packed pages. It took me about 15 minutes to read (and I am a slow reader) and you’ll struggle to find a textbook as concise and which builds to a high level so rapidly. Plus it’s freely available online.

What does it cover?


This is a free, practical, clinically useful summary of EBM which takes you from first principles to interpreting medical statistics in 15 minutes.
