Using the best-available medical evidence in the context of patient values and preferences to support clinical decision-making is an essential clinical tool: Evidence-Based Medicine (EBM).
Psychiatry residents at Duke learn basic principles of EBM during scheduled didactic sessions in the early part of training. We cover critical appraisal of different research designs and articles with a specific focus on how to interpret the results and apply it to patient practice.
If you are not a resident at Duke, here is a short version. This is a self paced tutorial  that will guide you through the steps of EBM. This program was developed by the Medical Center Library at Duke University and the Health Sciences Library at the University of North Carolina at Chapel Hill.
For those who are interested in learning to teach EBM and taking it back to your own institution, this workshop might be of interest:
Teaching and Leading EBM:  A Workshop for Teachers and Champions of Evidence-Based Medicine. This is an an innovative 4-day workshop designed to help clinical leaders and educators enhance their EBM skills.
There are several other opportunities - EBM resource links at Duke Medical Library  - to learn and practice EBM in other departments at Duke.
Once you have been introduced to the basics, you might want more information on how to appraise the evidence from specific types of studies.

Meade, and Deborah J. Cook.
