Evidence based practice
The most efficient sources are those resources that contain pre-appraised summaries of individual studies, or syntheses of all available studies, on focused clinical topics. They may also include an assessment of the current state of the evidence in an area of clinical interest.
The lowest evidence resources are those that are completely unappraised, these are mostly the large number of individual primary studies. Each of these studies must be personally critically appraised for its applicability to a specific clinical scenario.
